Ehab,

Have you checked for a sitex.dll file ? It should be there. And it has to be executed from an EXE. You can't run a DLL by itself.

How can I call DLL from EXE directly ?

Ehab,

Please review samples\TestDLLP.prg

Yes you can. A DLL is considered an executable file by Windows.

Enrico,

Yes, of course, but you can't double click on a DLL and execute it, or type its name, press enter and execute it. Neither you can use WinExec() to run it.

It has to be invoked using LoadLibrary().

Normally yes, because a DLL is not write to be self-executing. But if you rename an EXE to DLL then you still can execute it.

Enrico,

> But if you rename an EXE to DLL then you still can execute it.

Thats because EXEs and DLLs have different headers and their startup codes are different. Windows recognizes the EXE even if you rename it.

Another major difference between them, as explained in Charles Petzold "Programming Windows" book, is that a DLL uses the DATA segment of the EXE that calls the DLL, thats why a DLL can attend multiple EXEs simultaneously.

Ops, you are right. I can rename the EXE with any extension and it is still executable.

as to finalize the conversation which batch should I use to create EXE application I use rdd server in it in new FHW June2006 ?
