Pryabu

Hi, Im using LoadLibrary function to load a dll.To call a function,we will use GetProcAddress.But how to assign a value to a variable in that dll. Can anyone pls help me? Thanks,

Maybe this would help:

#pragma data_seg (".commondata")
extern /*type-name*/ /*variable-name*/ = /* value */
#pragma data_seg ()

For more information, look here[^].

The documentation[^] says:

GetProcAddress Function

Retrieves the address of an exported function or variable from the specified dynamic-link library (DLL). ...

So you probnably can access exported variables the same way as functions.

Why don't you define an accessor function in the DLL? :)

The dll is given by some vendor. Just im using that one. I cant define functions in dll.

OK. As side note, it is really strange that the vendor exposes a DLL's variable. :)
