Re: How to trace the VC++.dll code from VC++.exe

Hi all,

I have a vc++.dll with each function defined as

extern "C" WINAPI EXPORT test(int i)
{

}

I have to write a vc++.exe to to call this function.

so i have written a VC++.exe(dialog based) as below:

//declare a callback function for the test API in .dll
typedef int (CALLBACK* LPFNMLTPLY)(int);

Added a button test in a dialog and when u click it it executes the
following code

void CDynamicLoadDlg::Ontest()
{
   UpdateData();
    CHAR szTemp [100]; // for storing error code & message
   HINSTANCE hClcltr=LoadLibrary("nameofdll.dll"); //Loading dll into
calling processaddress
   LPFNMLTPLY lpfnMuliply; // see top of file for its defination
   if (hClcltr) //If DefExported.dll loded
   {
       lpfnMuliply = (LPFNMLTPLY)GetProcAddress(hClcltr,"test");
       if (lpfnMuliply) //If Multiply functin found and get its address
       {
           m_ParOne=1;
           m_Rslt=lpfnMuliply(m_ParOne);
           UpdateData(FALSE);
       }
       else
       {
           wsprintf (szTemp, "GetProcAddress failed. \nError code: %d",
               GetLastError());
           MessageBox(szTemp); //Show why GetProcAddress failed?
       }
       FreeLibrary( hClcltr );
   }
   else
   {
       wsprintf (szTemp, "LoadLibrary failed. \nError code: %d",
           GetLastError());
       MessageBox(szTemp); //Show why LoadLibrary failed?
   }
}

I am able to call the .dll function but the problem is i am not able
to trace the .dll code.Is my vc++.exe is correct.

Can anyone tell me what settings i have to do so that i can trace the
vc++.dll code
