PInvoke

[Saksida Bojan]

How does .NET handles a winapi that doesn't exsist on current OS, for example: If it was proggramed on Windows 7 64bit and then attempted to use on Windows XP 32 bit? API IsWow64Process does exsist in 64 bit OS, but does it exsist in 32bit version? edit: Re-edited question

P/Invoke problems are signaled through exceptions, see here[^] for some details. So you may choose to use some try-catch construct. :)

Thank you, as other question does IsWow64Process exsist in 32 bit Windows?

I don't know. Read the documentation. Google. Try it. :)

Then you get an exception "EntryPointNotFoundException" -> Function doesn't exists. IsWow64Process is also in Win32. See this: http://msdn.microsoft.com/en-us/library/ms684139%28VS.85%29.aspx[^]
