Hi,

Can anyone help me to call a VC++ dll function which has "memory space address" as an argument using vb.net?

VC++ code
---------
<code>
EXTERN_C void FAR PASCAL EXPORT CreateGUID(BSTR* bstrGUID,short ID)
{
CString strGUID;
AfxBSTR2CString(&strGUID, *bstrGUID);
ACNCreateNewGUID(strGUID,ID);
*bstrGUID = strGUID.GetBuffer() ;
}
</code>

The dll name is "GUIDdll". Please share me the vb.net code snippet like "Public declare function CreateGUID lib "GUIDDll.dll".... to me?

Thanks,
Sivakumar.M.

Solution 2

C#

[DllImport("GUIDDll.dll")]
public static extern void CreateGUID(String bstrGUID,Uint ID);

Bstr can be replace with string Bstr is a pointer to a array of character (which is equivalent to string).

The above mentioned is a C# code can be used with some modification in Vb.net too

Hope this helps :)

Solution 1

Couldn't you just use the Guid.newGuid[^] method, the .NET Framework gently hands you?

Sorry...our clients are using the above vc++ dll to create the GUID in some different way. Our tool will only accept the GUID, creates by this vc++ dll only. That's why i am asking how to pass the values to this fucntion.
