hi!

I' have a little problem.
I have made a isapi that returns wap pages.  Tis application reads a ini
file that is usually allocated in c:\winnt.
I have to add a new function to the application so it has to write in that
ini file,  but the usser of the internet information server don't have the
rights to write in that folder.  So I decided to put the ini file in the
same path of the dll, but I can't figure the way to get the path of the dll.
All I get is the path of  dllhost.exe.  (Application->ExeName)

I found an example in delphi, but i can't translate it to C++ Builder
because I don't know what is "hInstance"

var
  szFileName: array[0..MAX_PATH] of Char;
  DirStr : string;
begin
  GetModuleFileName(hInstance, szFileName, MAX_PATH);
  DirStr := ExtractFilePath(szFileName);


Ca you help me?

Call GetModuleFileName() using the HINSTANCE passed to the DLL's
DllEntryPoint() function.

You are not specifying the proper HINSTANCE when calling
GetModuleFileName().

That works....  but I don't know how to pass that information to the
Unit2.cpp

USEFORM("Unit2.cpp", PageProducerPage1); /* TWebAppPageModule: File Type */
char dllpath[1000];
//--------------------------------------------------------------------------
-
#define Application Webbroker::Application

#pragma link "isapiapp.obj"
#pragma link "isapithreadpool.obj"
#pragma link "webbroker.obj"
#pragma link "webinit.obj"
//--------------------------------------------------------------------------
-
int WINAPI DllEntryPoint(HINSTANCE hinst, unsigned long reason, void*)
{
  try
  {
    GetModuleFileName(hinst,dllpath,1000);

    if (reason == DLL_PROCESS_ATTACH) {
      CoInitFlags = COINIT_MULTITHREADED;
      Application->Initialize();
      Application->Run();
    }
  }
  catch (Exception &exception)
  {
  }
  return 1;
}

One way it to simply declare dllpath as 'extern' in Unit2, ie:

    --- MyDll.cpp ---

    char dllpath[MAX_PATH+1];

    int WINAPI DllEntryPoint(HINSTANCE hinst, unsigned long reason, void*)
    {
        if( reason == DLL_PROCESS_ATTACH ) {
            GetModuleFileName(hinst, dllpath, MAX_PATH);
            //...
        }
    }


    --- Unit2.cpp ---

    extern char dllpath[];

    // use dllpath as needed...
