Hello,

I have a VS project that has the Configuration type set to Makefile and
basically calls a ToolApp (EXE) I wrote that goes through the project's
sources and calls the compiler/linker, etc.  It all works well when I have
the solution/project opened in VS .NET 2003 IDE, but I would like to make
builds at night, so I call from the command line:

devenv.exe "C:\myproject.sln" /build "Debug" /project "myproject"

My ToolApp gets called correctly, but looks like I'm not able to get a
pointer to DTE anymore (needed to get the solution, project and collection of
files in the project), is there any way to get this when devenv.exe is called
from the command line as above?  This is what I've tried:

hr = CLSIDFromProgID(OLESTR("VisualStudio.DTE"), &clsid);
if (SUCCEEDED(hr))
{
   hr = GetActiveObject(clsid, NULL, &pUnknown);
  // hr is -2147221021 when ran on the command line
   if (SUCCEEDED(hr))
   {       //I don't get in here if ran from the command line
         pUnknown->QueryInterface(__uuidof(EnvDTE::_DTE), (LPVOID*)&gDTE);
...

Please don't tell me I have to parse the .vcproj to get the settings, and
project files...   :-)

thanks in advance
