Hi there, I am trying to pass an array of data from a DLL written in C/C++, how can I do that? The size of the array is not fixed. Thanks You.

What version of VB? VB 4.0 and 5.0 uses OLE's SAFEARRAY.

Passing Array of data from DLL to VB
Check out the file called VB4DLL.TXT on the VB cd in the directory VB. It tells you the correct types for VB arrays. It shoulds be the same on the VB5 CD, but I don't have it so I can't verifiy. A great source for writting DLL's for VB, is any of the Daniel Appleman's Programers Guide to API. It shows you how to recieve all types of VB data, except VB string arrays. Hope that helps.
