FIX: Launching COM Server with Long File Name Returns 0x80080005 (179690)


The information in this article applies to:

  • The Microsoft Active Template Library (ATL) 2.1, when used with:
    • Microsoft Visual C++, 32-bit Enterprise Edition 5.0
    • Microsoft Visual C++, 32-bit Professional Edition 5.0
  • Microsoft Windows NT Server 4.0
  • Microsoft Windows NT Workstation 4.0

SYMPTOMS

A COM local server fails to start, accompanied by the error "Server Execution Failed" (error number 0x80080005 or -2146959355), if it is registered in a directory with a long file name that contains a space and a similar directory name exists at the same level.

If the server is registered with a short file name, this problem does not occur. This is not a problem for inproc servers. All ATL local servers are registered with long file names.

CAUSE

This problem is caused by the fact that unquoted long file names containing spaces are ambiguous to CreateProcess (which is called by CoCreateInstance/ CoGetClassObject). Refer to the CreateProcess documentation for more information.

RESOLUTION

This problem can be fixed by overriding the registration functions in the CComModule derived class and adding code to use the short file name in registration instead of the long file name. MFC uses short file names for registration.

  1. Change CExeModule definition in StdAfx.h as follows: 
          class CExeModule : public CComModule
      {
      public:
         LONG Unlock();
         DWORD dwThreadID;

      #ifdef _ATL_STATIC_REGISTRY
      // Statically linking to Registry component.

         HRESULT WINAPI UpdateRegistryFromResourceS(UINT nResID,
            BOOL bRegister, struct _ATL_REGMAP_ENTRY* pMapEntries = NULL);
         HRESULT WINAPI UpdateRegistryFromResourceS(LPCTSTR lpszRes,
            BOOL bRegister, struct _ATL_REGMAP_ENTRY* pMapEntries = NULL);

      #else

         HRESULT WINAPI UpdateRegistryFromResourceD(LPCTSTR lpszRes,
            BOOL bRegister, struct _ATL_REGMAP_ENTRY* pMapEntries = NULL);
         HRESULT WINAPI UpdateRegistryFromResourceD(UINT nResID,
            BOOL bRegister, struct _ATL_REGMAP_ENTRY* pMapEntries = NULL);

      #endif
      };
  2. Add the following code to <ProjectName>.cpp after the #includes: 
          #ifdef _ATL_STATIC_REGISTRY
      #include <statreg.h>
      #endif
  3. Add the following code to <ProjectName>.cpp before _tWinMain(): 
          #ifdef _ATL_STATIC_REGISTRY
      // Statically linking to Registry component.

      HRESULT WINAPI CExeModule::UpdateRegistryFromResourceS(UINT nResID,
         BOOL bRegister, struct _ATL_REGMAP_ENTRY* pMapEntries)
      {
         USES_CONVERSION;
         CRegObject ro;
         TCHAR szModule[_MAX_PATH];
         GetModuleFileName(_Module.GetModuleInstance(), szModule,
            _MAX_PATH);

         TCHAR szModuleShort[_MAX_PATH];
         // Convert to short file name.
         if (::GetShortPathName(szModule, szModuleShort, _MAX_PATH))
         {
            lstrcpy(szModule, szModuleShort);
         }

         LPOLESTR pszModule = T2OLE(szModule);
         ro.AddReplacement(OLESTR("Module"), pszModule);
         if (NULL != pMapEntries)
         {
            while (NULL != pMapEntries->szKey)
            {
               _ASSERTE(NULL != pMapEntries->szData);
               ro.AddReplacement(pMapEntries->szKey, pMapEntries->szData);

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This problem was corrected in Visual C++ version 6.0 for Windows.

MORE INFORMATION

Steps to Reproduce Behavior

  1. Create two directories, C:\Program Files and C:\Program.
  2. Copy an ATL local server to C:\Program Files.
  3. Register the server.
  4. Attempt to start the server from a client application. Note that the server does not start and CoCreateInstance returns error 0x80080005.
  5. Copy and register the local server in the directory C:\Program.
  6. Attempt to start the server from a client application. Note that the server starts. No errors are returned.
NOTE: Surrounding the long file name in the registry with quotation marks does not solve this problem.
