DLL-problems!!!

[vbAlex]

hi

i created a dll with one function. i compiled this dll and created a normal exe project and wanted to test the dll.
i declared the dll and wrote some code.
but when i want to call the function in the dll, vb says, i wasn't able to find the point in the dll.
this is the first time, i work with dlls.
please help me!!!

It depends. If you created this DLL in VB then this DLL is an ActiveX DLL. So you have to add a reference to this DLL by going to Project-->References....

If you created this DLL in C/C++ or Delphi as static DLL then you have to declare this dll like:

Private [Public] Declare Function YourFunctionName Lib "YourDLLName" (ByVal YourParameter As YourDataType) As Long

thanx, do i have to create the reference on the other (default exe) project???

No, basically, when you're creating a new project and want to use your DLL, then you would set a reference to that DLL (put a check mark on the DLL you've created in the reference List). Then you would declare a variable as your DLL's class.

Dim oMyVariable As New YourDLL.YourClass


Then you would use the function that you've created:

Call oMyVariable.MyFunction(YourParameter)

THen, you compile your EXE. And when you give this EXE to the user, you would have to give him/her this DLL as well. But the best way is to create a Setup for your program. VB5 has Setup Wizard (VB6 Package and Deployment Wizard) which will include all needed files for your aplication.
