Hi,
I try to make DLLs for DB pro, and first, I trained on TESTCOMMANDS, but there is an error when the code is compiled :

Error
Could not find function '?PrintText@@YAXPAD@Z' in 0:dbprocore.dll

This appears in a dialog box.

I use Code::Blocks to create the DLL, and I import the TESTCOMMANDS example, using the option "Import Visual C++ Project".

The code is the same between CB project and VC project, I really don't understand the problem...

is the string table correct?

Science, Mathematics, and Physics do not lie - only people do.

Which compiler are you actually using? They all mangle the function names in slightly different ways, so as CR suggests, your string table may not be right.

I've kept exactly the code which is with the DB documents, including the string table :

I use MINGW32 to compile the DLL.

thats the problem - as the example uses the ms compiler

you will need to get the decorated function name from the dll, by either using depends(google for it) or by opening it in notepad and finding the name

Quote: "uses the ms compiler"

The Visual C++ Toolkit 2003 doesn't have the files needed, and Visual C++ Express 2005 detects an error when the code is compiled...

Is there another free MS compiler ?

Multiples errors now,
First, it was an error about the miss of windows.h file.

I add it with all other headers link to it, and now, there is 8 errors, about unknown pragma(pop) - the poppack.h is in the compiler...

I don't really understand where is the problem.

I added to VCE all win32 headers it needed, but no .lib/.a file, I suppose the problem is linked to this.

Is there someone who knows how to solve this problem ?

You need to download and install the latest platform SDK for the VC2005 compiler. An older one just won't cut it.
