Hello,
First, I created a storage file using StgCreateDocfile() then added some files in it. Then i tried to open this storage file using

MIDL
hr = StgOpenStorageEx(L"E:\\Storage.stg",STGM_READ|STGM_SHARE_DENY_WRITE,STGFMT_DOCFILE,0, NULL, 0,IID_IStorage,(void**)&pStorage);


which worked fine when i did it win32 console application.

But when i tried it add the same code in Windows form application project, adding a c++ class to project and then my code to that class, it generate a runtime error
VB
1>Recovery.obj : error LNK2020: unresolved token (0A000017) IID_IStorage
1>Recovery.obj : error LNK2001: unresolved external symbol IID_IStorage


whats the problem with IID_IStorage in newly created class.

Do i need to do something with Linker properties in project setting?

It seems you are missing a lib file. Try adding Uuid.lib to your linker libraries.

As you mentioned , i have added Uuid.lib in Properties->linker->Input->additional dependencies..
But i didnt worked....
I think you may need to include Objidl.h in your source code as described here[^] in MSDN.

Objidl.h is already added... i wont be getting this error if i would have missed to include Objidl.h...
My problem is :- my code worked fine in windows console application project, but in windows form application as project type, i created a c++ class and added same code in it..but seems to have some problem for IID_IStorage parameter in "StgOpenStorageEx()" function which is leading to LNK 2020 and 2001 error..
