I figured out why it doesn't work in visual studio c++. Here is the correct code I used to fix my error C2143:
#include "Wave.h" /* This header file has the CWave class in it */
CWave *wave1;
int main()
{
wave1.Load(_T("C:...\Music.wav"));
wave1.Play();
Sleep(100000);
}

Is that the working directory of your application ? Make sure this is the case. I'm not a C# expert but I suppose you can find that in the project options.

yes i put it in working dir

you need to put the mangled name for the function.
[DllImport("/*put the path of the dll*/")]
public static extern int Add/*mangled function name instead of Add*/(int a, int b);
You need to google first, if you have "It's urgent please" mentioned in your question.

Are you talking about any Source Code Management tools ?
Please go through these sites and rephrase the question ...

This article[^] has what you need - a class to read the version resource of a module.

Hi
I want to use a C++ program as a part of a project in C#
and I know how can I do this when the program is Managed CPP
But I want to know how can I include my Standard Cpp code in a C# project
and I use Visual Studio 2008 and I want to know is there any template for creating
a standard CPP project apart from the "Empty Project"?
I appreciate your answers
thank you

You cannot directly use native C++ code in C#.
You can create a native C++ DLL and then do DLL interop from C#.

Thank you
It would be better if you told me how to do that
and again thank you

Hi,
I'll recommend that you write everything in managed code, or everything in native language as much as possible. If you mix them both, you don't get the best of both worlds, but in most cases, you get the worst of both worlds. Like the other person said, you cannot directly use C++ code in a managed application. Try converting that to managed C++. Keep COM interop as the last option (there are several articles on CP and msdn, if you decide to, just do a search).

i have used CMFCOutlookbar in my project, and i have added some tabs to it.
every thing works fine except to set the color for the tabs.
i am using SetTabBkColor(int itab, COLORREF clr) function.
but the color is not getting applied at all.
is that i am missing something?
code snippet:
CMFCOutlookbarTabCtrl * pTabCtrl = (CMFCOutlookbarTabCtrl * ) m_wndOutlookbar.GetUnderlyingWindow();
if(pTabCtrl)
{
pTabCtrl->SetTabBkColor(0, RGB(100, 100, 100));
}
although the function returns success, the color is not visible for the tabs.
suggestions are welcome
thanks
