I'm creating a search form using an asp:button control with the urlpostback set to a results page. The problem is, the asp:button uses Visual Basic and the search results from Google require Javascript.
Is there a way to take the data from an asp: textbox in VB and then send it to another page that uses Javascript and use the data?

I'm using Visual Studio 2010 and my software will be a Windows Forms Application.
I know it's possible to retrieve URL source codes, slice and dice them either through VB.NET or RegEx but that only applies to text/code that are in plain text like HTML code. But how do you extract code from JavaScript that in the downloaded source code doesn't display the data inside the variables, but instead the actual variables?
Below I have an example code of JavaScript variables inside a downloaded .HTML source code that, when the webpage is loaded, displays the information/data contained inside these variables in the web browser. But the data itself isn't "downloaded" or stored in the source code.
So my question is: How do you extract/retrieve the data from within those JavaScript variables?
<td>
<div class="showUserText">
<div class="outerRatingBody" style="display:none;" >
[Code]....
Is it possible through VB.NET to get what ever is inside those variables?

I'm making a presentation program. It's a bit like PowerPoint, but less complicated and for a different purpose.
All files used in the presentation (like images, texts and sounds) should be put into a single 'file-package'. This package should later be opened by my program, which should be able to use the files from the package. (Just like PowerPoint creates a single file with all images and sounds included, which can be loaded in PowerPoint on a different computer.)
Actual compression for the file is not really needed. It could be sort of like a tar-file.

I want to have a backup feature which takes about 7 txt files and compresses/packs them into one file. Then if required at a later stage I can unpack all 7 files from the packed file. I do not need any compression as such just to make one file from 7, then 7 from from that one, if you understand what I mean. I have read there are some native libraries in .NET Framework 2.0 called DeflateStream and GZipStream. Can these be used?

So right now it all looks pretty with ... <button type="submit" runat="server" name="subscribe" id="Button1" class="link-button" onserverclick="saveListing"> Until it is time to validate the data before calling saveListing function codebehind (in VB .Net). How can true/false be return so that when true saveListing will be called, otherwise not?

How can i encrypt or decrypt only a part of a file? I try, and i keep getting an error message that says that the stream might be corrupt. By the way, it is ok to convert the text to a byte array using the system.text.encoding.ascii.getbytes() right? The reason i want to encrypt/compress only a part of a file is because i don't want to encrypt or compress the file header. That way the program can gather info about whether the file is compressed or encrypted.

I have a program I made in vb.net express 2008 that used java.utils.zip to compress my work files to a Zip archive that I ran occassionaly to have a backup. I worked fine, but with net framework 4 and vb.net 2010 it doesn't work. So I modified it to use sharpziplib and it works fine if all files on the filter list in the folder are closed, but if I have a file open in OpenOffice writer, my program can't access it and won't create the zip file. The file that usually stays open all the time is my TODO list, that is updated several times a day , so usually gets printed, and updated( adding or deleting entries), without closing it.

I'd like to use WinRAR's dll file to compress files in vb.net.Is there any way this can be done? The only one I found was using the unrar.dll to uncompress files. Also, I'd like to know how to implement WinZIP's dlls to compress files as the zipfldr.dll does not achieve very high levels of compression and encryption.

I have a web application using VB ASP.NET 3.5 that along with many things allows users to upload documents into a directory on the web server. I would like to know how I can zip a folder on a webserver and download it to the client machine via a submit button.Currently, I have the files displayed as URLs so that the users can right-click and "Save Target As." But I think just having everything zipped in one file would make it alot easier for the users.

I wonder if you can help. I have an intranet with about 2000 photos on it. A lot of these photos were not compressed when uploaded so can be upwards of 4 or 5MB in size.
Is there a script/tool I can run to go through the directory one image by one and automatically and compress each images to say 100k or percentage of the current file size, then save and close the file with the same name?
