FIX: C1001: msc1.cpp, Line 581, Prototype Missing Semicolon

The information in this article applies to:

• The Microsoft C/C++ Compiler (CL.EXE), included with:

      - Microsoft Visual C++ for Windows, version 1.0
  

SYMPTOMS

An attempt to compile the source code below fails and the C/C++ compiler generates following messages:

   error C2085: 'hInst' : not in formal parameter list

   error C2061: syntax error : identifier 'HWAVEIN'

   fatal error C1001: internal compiler error
     (compiler file 'msc1.cpp', line 581)

RESOLUTION

To eliminate the C1001 internal compiler error, first correct the other errors in the code. To do so, terminate the MakeInstanceActive() function prototype with a semicolon (;).

STATUS

Microsoft has confirmed this to be a problem in the products listed at the beginning of this article. This problem was corrected in C/C++ compiler version 8.0c, included with Visual C++ for Windows, version 1.5.

MORE INFORMATION

The errors above occur because a semicolon is missing from the MakeInstanceActive() prototype. This error causes other errors later in the file.

Sample Code

/*
 * Compile options needed: none
 */

#include <windows.h>

HANDLE hInst; HWAVEIN ghWaveIn = NULL;

WORD    gwWantToClose = FALSE;

int PASCAL WinMain(HANDLE hInstance,
                   HANDLE hPrevInstance,
                   LPSTR  lpCmdLine,
                   int    nCmdShow)
{
   MSG msg;

   if (hPrevInstance)
      {
      MakeInstanceActive("TestClass");
      return FALSE;
      }

   if (!hPrevInstance & !InitApplication(hInstance))
      return (FALSE);

   if (!InitInstance(hInstance, nCmdShow))
      return (FALSE);

   while (GetMessage(&msg, NULL, NULL, NULL))
      {
      TranslateMessage(&msg);
      DispatchMessage(&msg);
      }

   return (msg.wParam);
