Help registering a dll

[William Cruz]

Using: "regsvr32 expcg.dll" I get this error message: "expcg.dll was
loaded, but the DllRegisterServer entry point was not found. the file
can not be registered."

That means that the DLL is not not an ActiveX DLL...

If you're trying to register a .NET assembly for use with COM use regasm.exe
instead

I'm wanting to use my DLL app in VBA for AutoCAD.

What steps do I need to take to make my DLL an ActiveX.

First you must decide if you want to create:

- A .NET assembly Dll: in this case the Dll can be registered for COM
Interop using regasm.exe. See COM Interop in the MSDN docs. For example:

Exposing .NET Framework Components to COM
http://msdn2.microsoft.com/en-us/library/zsfww439(VS.80).aspx

- A native ActiveX dll: in this case you can´t use a .NET language but you
can still use VS.NET to create a Visual C++ DLL, or use VB6, etc.

You can just save the dll in the same folder where your application
exists. This would help, if your dll is not a activex dll.

I have done the first of your suggestions. I registered the DLL using
regasm.com in this manner: “regasm expcg.dll /tlb:expcg.tlb”. I then
went into VBA for AutoCAD and went to “add reference” and then “expcg”
to add as a reference, this all works fine. I then declare it this way:
“Dim Calcs As New ExpCG.ExpCG_Calcs” This also goes as planned. Now when
I try to use it, I get an error. I try to use it this by setting a value
withing the dll “Calcs.UnitWeight = 144” and I get this error.

Run-time error ‘-2147024894 (80070002)’:
The system cannot find the file specified.


Before using regasm.exe, I copied the dll file from the project
directory into the Windows\system32\ directory.

Hi,

Try registering the DLL with the codebase flag:

regasm.exe /codebase expgc.dll etc
