HELP! Error, cannot run and cannot install!!

I've written a program which "read data" from the school server. There is a webbrowser control in the program, which read a HTML page from the server, and the VB will find the information from the HTML document. I used

Code:

---

instr(WebBrowser1.DocumentText, information)

---

This works fine on my computer, which is:
- Vista x64
- built in IE7
- VS 2008 (with .Net Framework 3.5)

However, the program doesn't work on my friend's computer, which is a XP machine. The program can be run, but the function doesn't work. There IS such a string within the same HTML document, but no reaction triggered by the "instr" statement. Is it the problem that ".documenttext" works only on IE7, but not IE6?

Another problem is that, is it all program written by VS2008 (.Net Framework 3.5) cannot be run on .Net Framework 2.x installed machine?

Thanks for answering my questions!!

Hi all

I've put make a tester (a webbrowser control only with instr function) with VS2005. While it runs, an error shows up

Code:

---

System.io.filenotfoundexception

---

I search it on the Internet, and I think it should be a bug. I've tried to include the mshtml.dll with the project for installation, but this doesn't help. (I meet the problem even though my machine has VS2005!) I cannot find any solution from MS. The program works fine on my VS2008 installed laptop, and this may mean the bug doesn't exist in .Net framework 3.5... Maybe I should force the users to install 3.5, as this should be the only way to "solve" the problem...

Well your developing on a 64 bit syste, so you should be using 64 bit 3.5 framework. This may be causing teh issue when going to the XP system which is 32 bit.

I've tried to use x86 computer to write a tester with webbrowser and instr function. This doesn't work either!

i am trying to use axwebbrowser, this works in my xp, but doesn't work in my vista and my friend's xp! strange...

Well, i'm not sure, but I think that Virtual PC runs as a x32 environment regardless of whether the hardware is x64. So when you leave the Virtual PC and try to run your program within a native x64 environment like Vista x64, it's causing errors. Not many things run at x64 yet. If you want them to, I do think that you can actually specify that you're coding for x64 within VS2008, but again, not sure.
