I have to access a function in a dll using the macro script. I tried using the 'LibFunc' to get that function in the dll, but it return a message 'Unable to load the dll'. I tried usiong the below given code snippet

LibLoad>C:\Program Files\DM\dm_1.dll,hIE
If>hIE=0
MessageModal>Could not load dm_1.dll, make sure it is in the path or edit the LibLoad line.
Goto>end_script
else
MessageModal>Loaded
LibFunc>hIE,getSequenceID,r
MessageModal>%r%
LibFree>hIE
EndIf
Label>end_script

The 'getSequenceID' is a method in the dll.Please help

Then it is hard for me to comment.

Which version of Macro Scheduler are you using? Is the path correct? What was used to create the DLL? Are you able to load it from other languages, e.g. C++ or VB?

The LoadLibrary function is used by Macro Scheduler to load the DLL. The MSDN documentation may give you some clues:

If you want me to take a look, you will need to send me the DLL.

The path of the dll seems to be right and we are using Macro scheduler 11.1. The dll we are calling is created in vb.net 2003.

We are having a class within the dll and the function resides within the class. So could you please help us how to access the functions in the class from Macro Scheduler.(The dll is created in vb.net).

Sounds like you have created a COM component, not a regular DLL.

LibLoad is for regular C style DLLs. If you can load your DLL with LoadLibrary in any other language then you can load it with Macro Scheduler.

I don't even know if you can create regular DLLs with VB.NET. If you have created a COM component then you might be able to use it with VBScript using CreateObject.

Really without seeing your code I can only guess.

Hi rraghul,

Would you be allowed to create a sample dll using the same technique?

Marcus may be able to provide a solution using the sample instead of your real code.
