How to detect Scroll position of a webpage using jQuery's .scrollTop()

The .scrollTop() function in jQuery allows you to get the current vertical position of the scroll bar for the first element in the set of matched elements or set the vertical position of the scroll bar for every matched element. 
 
You can extract the scroll position of a certain page or element using the <a href="http://api.jquery.com/scrollTop/" rel="nofollow" target="_blank">jQuery's .scrollTop() method</a>. 
 
 
<pre class="brush: java">$(window).scroll(function (event) {
 var scroll = $(window).scrollTop();
 // Do something
});</pre>
 
You can also determined the percentage and alert the user that he has scrolled certain amount within the document. 
<pre class="brush: java">$(document).scroll(function(e){
 
 // get the scroll value and the document height
 var scrollVal = $(window).scrollTop();
 var docHeight = $(document).height();
 
 // calculate the percentage when the user scrolls down the page
 var percentage = (scrollVal / docHeight) * 100;
 
 if(percentage > 50) {
 // call the function called alertUser
 alertUser(percentage);
 }
 
 function alertUser(scrollPercentage) { 
 // alerts the user that he has scrolled certain amount within the document
 alert("You have scrolled down at " + scrollPercentage + " of this page");
 }
 
});</pre>

VB.Net Print PDF Document

12:27 AM OmelSoft 1

Portable Document Format (PDF) is a file format used to present documents in a manner independent of application software, hardware, and operating systems. Each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, graphics, and other information needed to display it. 
 
In some applications, web or desktop there are several options where you can convert or Print a PDF version of a form or document you're reading. So, the question is how is it done and is it possible to create your own PDF document from scratch? We'll you're still lucky as I am.

Formatting Date and Time VB.NET

10:07 PM OmelSoft 1

The Date literal must be enclosed within number signs (#date#) and specify the date value in the format M/d/yyyy like #09/06/2014#. Else, the way how your code is interpreted may vary depending on the locale in which your application is deployed. 
 
With this requirement the meaning of your code should never change whether if it has a different date and time format settings. For example, you hard-coded a Date literal of #9/6/2014# which means September 6, 2014. That will compile 9/6/2014 as you want mm/dd/yyyy. However, if you deploy application in several locales using dd/mm/yyyy date format, your hard-coded literal would compile to June 9, 2014. For other locales using yyyy/mm/dd, the literal would be invalid causing compilation error. 
 
To convert a Date literal to the format of your locale or to a custom format, use the Format function of String class, specifying either a predefined or user-defined date format. 
 
<h2>
Predefined Date/Time Formats</h2>
The following table identifies the predefined date and time format names. These may be used by name as the style argument for the Format function: 
<table cellpadding="0" cellspacing="0"> <tbody>
<tr> <th>Format Name </th> <th>Description </th> </tr>
<tr> <td>General Date, or G </td> <td>Displays a date and/or time. For example, 3/12/2008 11:07:31 AM. Date display is determined by your application's current culture value. </td> </tr>
<tr> <td>Long Date, Medium Date, or D </td> <td>Displays a date according to your current culture's long date format. For example, Wednesday, March 12, 2008. </td> </tr>
<tr> <td>Short Date, or d </td> <td>Displays a date using your current culture's short date format. For example, 3/12/2008. The d character displays the day in a user-defined date format. </td> </tr>
<tr> <td>Long Time, Medium Time, or T </td> <td>Displays a time using your current culture's long time format; typically includes hours, minutes, seconds. For example, 11:07:31 AM. </td> </tr>
<tr> <td>Short Time or t </td> <td>Displays a time using your current culture's short time format. For example, 11:07 AM. The t character displays AM or PM values for locales that use a 12-hour clock in a user-defined time format. </td> </tr>
<tr> <td>f </td> <td>Displays the long date and short time according to your current culture's format. For example, Wednesday, March 12, 2008 11:07 AM. </td> </tr>
<tr> <td>F </td> <td>Displays the long date and long time according to your current culture's format. For example, Wednesday, March 12, 2008 11:07:31 AM. </td> </tr>
<tr> <td>g </td> <td>Displays the short date and short time according to your current culture's format. For example, 3/12/2008 11:07 AM. </td> </tr>
<tr> <td>M, m </td> <td>Displays the month and the day of a date. For example, March 12. The M character displays the month in a user-defined date format. The m character displays the minutes in a user-defined time format. </td> </tr>
<tr> <td>R, r </td> <td>Formats the date according to the <a href="http://msdn.microsoft.com/en-us/library/system.globalization.datetimeformatinfo.rfc1123pattern.aspx"> RFC1123Pattern</a> property. For example, Wed, 12 Mar 2008 11:07:31 GMT. The formatted date does not adjust the value of the date and time. You must adjust the Date/Time value to GMT before calling the Format function. </td> </tr>
<tr> <td>s </td> <td>Formats the date and time as a sortable index. For example, 2008-03-12T11:07:31. The s character displays the seconds in a user-defined time format. </td> </tr>
<tr> <td>u </td> <td>Formats the date and time as a GMT sortable index. For example, 2008-03-12 11:07:31Z. </td> </tr>
<tr> <td>U </td> <td>Formats the date and time with the long date and long time as GMT. For example, Wednesday, March 12, 2008 6:07:31 PM. </td> </tr>
<tr> <td>Y, y </td> <td>Formats the date as the year and month. For example, March, 2008. The Y and y characters display the year in a user-defined date format. </td> </tr>
</tbody> </table>
 
<h2>

<table cellpadding="0" cellspacing="0"> <tbody>
<tr><th>Character </th> <th>Description </th> </tr>
<tr> <td>(:) </td> <td>Time separator. In some locales, other characters may be used to represent the time separator. The time separator separates hours, minutes, and seconds when time values are formatted. The actual character that is used as the time separator in formatted output is determined by your application's current culture value. </td> </tr>
<tr> <td>(/) </td> <td>Date separator. In some locales, other characters may be used to represent the date separator. The date separator separates the day, month, and year when date values are formatted. The actual character that is used as the date separator in formatted output is determined by your application's current culture. </td> </tr>
<tr> <td>(%) </td> <td>Used to indicate that the following character should be read as a single-letter format without regard to any trailing letters. Also used to indicate that a single-letter format is read as a user-defined format. See what follows for additional details. </td> </tr>

VB.NET's DateTime structure represents an instant in time which is commonly expressed as a particular date and time of the day. It's a part of your daily life while creating your applications which makes it easy for you to manipulate system's date and time. In this article I'll be showing you the commonly used properties and methods and example usage of the Date and Time in VB.Net. Use the Date data type to contain date values, time values, or date and time values. The default value of Date is 0:00:00 (midnight) on January 1, 0001. You can get the current date and time from the DateAndTime class. <h2>DateTime Properties</h2>The table below shows some of the commonly used properties of the DateTime Structure: <table

Using Named Ranges in Microsoft Excel

12:19 AM OmelSoft 0

Named Ranges in Excel enable you to give one, or a group of cells a name other than the default B4 for a single cell, or B2:E20 for a range of cells. So that you can refer to them in formulas using that name. <div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh06uGkSJiDjEkLowyCcjAHY6jQY4WXTWrTaGY8kgpxuc81T9jgywX-7QngTbGR0hSC-o5YclSKKEaUCH02Cz_-QH0-KHzOI79pnusRVXHVaOhQYwbUZXLHBzW-FCzHXR0yFZ5FQCv3aFJh/s1600/Named+Range+Example.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="146" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh06uGkSJiDjEkLowyCcjAHY6jQY4WXTWrTaGY8kgpxuc81T9jgywX-7QngTbGR0hSC-o5YclSKKEaUCH02Cz_-QH0-KHzOI79pnusRVXHVaOhQYwbUZXLHBzW-FCzHXR0yFZ5FQCv3aFJh/s1600/Named+Range+Example.png" width="320" /></a></div> You can view the complete tutorial here <a href="http://excel-name-ranges.blogspot.com/2014/03/excel-2007-named-range-rules.html" target="_blank">How to Use Named Ranges in Microsoft Excel </a>. When using Named Ranges there are also set of rules which you need to know like the scope where you can use the specified named range. If it's within only a single worksheet or the entire workbook. Check this out <a href="http://excel-name-ranges.blogspot.com/2014/03/excel-2007-named-range-rules.html" target="_blank">Named Range Rules</a> and be totally aware of the do's and don'ts when using this functions. Managing Your Named Ranges There'll come a time when you want to edit or delete a Named Range. To do this access the Name Manager on the Formulas tab of the ribbon. The Name Manager Dialog box will open. <div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhdL-t-vDb3OoGSP28mbJX53I8dEhYb_qfK0c9KBU-VRNDRwzH5tnFQ6cJfO3Cnv8jz7roTMB_XXGTc3nUNNg7qIWjdLfVjHkBMeAg90WUQvE1PDOfy_A0upqP6D6vAF5ID6dMa_fRQqRPs/s1600/Name+Manager.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="76" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhdL-t-vDb3OoGSP28mbJX53I8dEhYb_qfK0c9KBU-VRNDRwzH5tnFQ6cJfO3Cnv8jz7roTMB_XXGTc3nUNNg7qIWjdLfVjHkBMeAg90WUQvE1PDOfy_A0upqP6D6vAF5ID6dMa_fRQqRPs/s1600/Name+Manager.png" width="320" /></a></div><div class="separator" style="clear: both; text-align: center;"> </div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi42HKWte4RD6Fk9GxpdIRGgBpY3V13Vyq-uNQkow1r21I7nZE5t4df-Xox7s9ojRgXuty8meAH1ixf1oYSlrCxo-Nhd8f8ljRCs3WPoynYoIEbdKSWlo6Eqx8D7MyKs-GqqrNFLkWMHAGw/s1600/Name+Manager+Window.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="241" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi42HKWte4RD6Fk9GxpdIRGgBpY3V13Vyq-uNQkow1r21I7nZE5t4df-Xox7s9ojRgXuty8meAH1ixf1oYSlrCxo-Nhd8f8ljRCs3WPoynYoIEbdKSWlo6Eqx8D7MyKs-GqqrNFLkWMHAGw/s1600/Name+Manager+Window.png" width="320" /></a></div> From here you can Edit and Delete your Named Ranges, or even create new ones. Remember, once you delete a name you cannot undo that action. Different uses for Named Ranges in Excel: 1) Formula References: Simplify the creation and retrospective interpretation of formulas by using Named Ranges in your formulas 2) Multiple Print Areas on one worksheet; Selecting non-contiguous print areas is quick and easy using Named Ranges. Note: Excel 2007 onward allows you to set multiple print areas on the Page Layout Tab of the Ribbon under Print Area. 3) Reduce worksheet clutter with Named Constants. Sounds complicated but it's not. A Named Constant is just a fancy name given to values you might use repeatedly in your formulas. For example, let's say you're planning to have a year-end inventory sale and wanted to give a 10% discount on selected products, you could give the value "10%" a name like "Discount" and then you could: <ul><li>Write your formulas like this =C1-(C1*Discount). This is more intuitive when you come to review the spreadsheet later, or for anyone else reviewing it.</li><li>Update the value globally by editing it once in the Name Manager. This will then automatically update the formulas.</li><li>Reduce clutter on your spreadsheet. Often a helper cell is set up with this key figure in to achieve these benefits, but if you've got many of these key figures your spreadsheets can become crowded.</li></ul> To create a Named Constant See--<a href="http://excel-name-ranges.blogspot.com/2014/03/how-to-setup-named-constant-in-excel.html" target="_blank">How to Setup a Named Constant in Microsoft Excel</a>.

Change/Remove the Password of a Password-Protected VBA Project in Microsoft Excel

7:28 AM OmelSoft 0

Some Excel VBA developers are protecting their codes and modules with password in order not to let others view the content of their project. It's okay to open these files if you really knew the purpose of the project. But, what if you're in a company having bundles of confidential information that you're not allowed to divulge to any other parties and the Macro runs Malicious Codes to obtain such information. Or in worst cases, can also be used to spread viruses over the network you're connected with. One day, you might have received an email from a friend with an excel file attachment containing macros in it. And you are told to open it because He/She has a data that needs to show to you. And when you open it, suddenly you're system got compromised. So if you have the basic understanding with the programming language (VBA), then you might want to know what are the codes and applications are running when you open the excel file. But that doesn't end there! <div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiLKgEcFqbByekEUe-1Mw9pwxK5nbV_ZHAJxYgh86qdZ_Pga1klHHyFltIvoPySx-4VIrrDWzGIn8FGRG6lPSXBZMQxJCmd6Nexa0_uP4MSa5S1nIcZ4Hk1mrgunQmveN9rvK_X_4FgAMC1/s1600/VBAProject+Password.png" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" height="135" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiLKgEcFqbByekEUe-1Mw9pwxK5nbV_ZHAJxYgh86qdZ_Pga1klHHyFltIvoPySx-4VIrrDWzGIn8FGRG6lPSXBZMQxJCmd6Nexa0_uP4MSa5S1nIcZ4Hk1mrgunQmveN9rvK_X_4FgAMC1/s320/VBAProject+Password.png" width="320" /></a></div>When you try to open and view the VBA Project it prompts you to input a password in which you don't have an idea unless if He/She gave it to you. And if you're good at guessing then guess the PASSWORD! We'll, I guess that's not a good idea. But the good news, is that you can set the VBA Project's Password to a password of your own. <input name="IL_IN_TAG" type="hidden" value="1" /> Changing/Removing the Password: So what do you need? 1.) You need to create a new Excel File with a known VBA Project Password.      a. Open Microsoft Excel, Press Alt+F11 to open the Microsoft Visual Basic window.      b. Set the VBA Project Password to '1234'. See <a href="http://tutorpinoy.blogspot.com/2014/01/how-to-set-password-on-your-excel-vba.html" target="_blank">How to Set Password on Excel VBA Project</a>.      c. Save the file as "password.xls" on your desktop or to location you can easily access.      d. Close the file. 2.) You will need any HEX Editor. You can download a free and portable HEX Editor <a href="http://www.pendriveapps.com/goto/HxD_Portable_Hex_Editor/695/2" rel="nofollow" target="_blank">here</a>.      a. After Downloading, extract the compressed package and open the<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhzPmZORjIRzQ5m3_vYeYmXigsChkLtmdQE_jeJ-yt_8z8EWem0pTRhHeqzX3h7_db0W4yElnGnL9j9comYQAzjnj5hyqt7aM-gpPvb06MeQRqAZXpheRFPPabxrwKeV6CwivuoAohEFW_z/s1600/HxD.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em; text-align: center;"><img alt="HxD.exe" border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhzPmZORjIRzQ5m3_vYeYmXigsChkLtmdQE_jeJ-yt_8z8EWem0pTRhHeqzX3h7_db0W4yElnGnL9j9comYQAzjnj5hyqt7aM-gpPvb06MeQRqAZXpheRFPPabxrwKeV6CwivuoAohEFW_z/s1600/HxD.png" title="HxD" /></a> on the output folder.      b. Browse the Excel File that you want to change/remove the password and the Excel file you've just created with a known password.      c. Drag and Drop the files on the HEX Editor's Window. As you can see below. <div class="separator" style="clear: both; text-align: center;"></div><div class="separator" style="clear: both; text-align: center;"></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhrjYbxyk2OLhVgI-6-jSsd9AV6C8yv_DZ55t_XT1w47QEV3ixauHEMdpGOClHsMMZ0Fubyqj5jIj1wolx5zpvPI3JY3dIWWgsH0WelljmjqJ_ICraz-yveTg74V6gw6dT-dLsBvsEjHq8k/s1600/HxD+Files+Opened.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img alt="HEX Editor" border="0" height="158" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhrjYbxyk2OLhVgI-6-jSsd9AV6C8yv_DZ55t_XT1w47QEV3ixauHEMdpGOClHsMMZ0Fubyqj5jIj1wolx5zpvPI3JY3dIWWgsH0WelljmjqJ_ICraz-yveTg74V6gw6dT-dLsBvsEjHq8k/s400/HxD+Files+Opened.png" title="HEX Editor" width="400" /></a></div><div class="separator" style="clear: both; text-align: center;"> </div>     d. Now on the HEX Editor's Window, Select the password.xls tab.      e. Press Ctrl+F, type "cmg" without the "" then press enter. CMG will now be highlighted.      f. Now, Select CMG and DPB values as you can see below and Press Ctrl+C to copy. <div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi_5_FOA8feTnQckJ-KszD2gcq63dGIF1_wrQuB5goxmyY7KHSEKxlL25ScU66WX7wbxDHP1QPjij6JTFxuW8_C2Lvw8LnD3tpYVdGHuFao0HMSToZU7-JT-NA1OtjkkW710HqTyzYDhymT/s1600/CMG+Found.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="85" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi_5_FOA8feTnQckJ-KszD2gcq63dGIF1_wrQuB5goxmyY7KHSEKxlL25ScU66WX7wbxDHP1QPjij6JTFxuW8_C2Lvw8LnD3tpYVdGHuFao0HMSToZU7-JT-NA1OtjkkW710HqTyzYDhymT/s400/CMG+Found.png" width="400" /></a></div>         g. Next, select the PasswordProtectedVBAProject.xls tab and repeat steps e & f.      h. Now that you've selected the CMG and DPB values of the Password Protect VBA Project. Press Ctrl+V to paste the ANSI data from the password.xls file.      i. Save the PasswordProtectedVBAProject.xls and close the HEX Editor Window. You can finally open the VBA Project! When you open the Password-Protected VBA Project, you'll now be able to open and view the modules and codes using the password '1234'. And then you found out that the macro is only saying "HELLO WORLD!" =:)
