Guide me to clear these bugs

[sudhavelvizhi]

I am new to VC++. I am working in Vista with VC++ 2008(professional-trial version)

I hav to create a front end for C program using buttons and all. It has to read the contents of text files. I got one example program from the following link,
http://support.microsoft.com/kb/307398

For this program i got the following error,
1>c:\kb307398\kb307398\Form1.h(22) : error C2059: syntax error : 'public'
1>c:\kb307398\kb307398\Form1.h(22) : error C2059: syntax error : 'public'
1>c:\kb307398\kb307398\Form1.h(23) : error C2143: syntax error : missing ';' before '{'
1>c:\kb307398\kb307398\Form1.h(23) : error C2447: '{' : missing function header (old-style formal list?)
1>.\KB307398.cpp(9) : error C2065: 'array' : undeclared identifier
1>.\KB307398.cpp(9) : error C2275: 'System::String' : illegal use of this type as an expression
1>.\KB307398.cpp(9) : error C2059: syntax error : '>'
1>.\KB307398.cpp(10) : error C2143: syntax error : missing ';' before '{'
1>.\KB307398.cpp(10) : error C2447: '{' : missing function header (old-style formal list?)

I hav verified even the braces match in Form1.h.

Post the EXACT code you're trying to compile.

That is C++/CLI code you are trying to compile, not C++.

I cleared those bugs...
Thank u for ur help.
I hav one more doubt.
Is it possible to call an .exe file from a button click.

[cilu]

Yes. Use CreateProcess() to create a new process.

And next time, please use CODE tags.

[sudhavelvizhi]

I tried some codes using createprocess().
But i'm getting lot of errors.
Can u giv me still some indepth idea abt this.
What is code tag? Where to use it?I dont know abt it.
