If you get error code 87 (witch is ERROR_INVALID_PARAMETER) when calling GetLastError(), this meen that you pass some invalid argument to this function.

No. Memory allocated by GlobalAlloc is not visible to other process. If you want to share memory across process, i sugest that you use memory mapped files. Also, MSDN state that GlobalAlloc is not the preferred way to allocate memory. Try the heap memory function instead (HeapAlloc, HeapFree, ect,ect).

Try... HANDLE LoadImage( HINSTANCE hinst, // handle to instance LPCTSTR lpszName, // image to load UINT uType, // image type int cxDesired, // desired width int cyDesired, // desired height UINT fuLoad // load options ); and set the hinst to NULL and lpszName to the filname you load,uType to IMAGE_BITMAP, fuLoad to LR_LOADFROMFILE. For other parameter and options look it up in MSDN. On success attach it (cast from HANDLE to HBITMAP).

I assume you working in MFC. Her Loadbitmap is declared as follow... BOOL LoadBitmap( LPCTSTR lpszResourceName ); BOOL LoadBitmap( UINT nIDResource ); Both tis function asume a resource ID. This resource ID can be a textvalue or UINT value. To load a bitmap from a file you can just call Win32 LoadBitmap API function (or LoadImage). On success then you attach it to the the CBitamp object.

Try.. BOOL HttpQueryInfo( HINTERNET hRequest, DWORD dwInfoLevel, LPVOID lpvBuffer, LPDWORD lpdwBufferLength, LPDWORD lpdwIndex ); and set dwInfoLevel to HTTP_QUERY_RAW_HEADERS or HTTP_QUERY_RAW_HEADERS_CRLF. You can se more on this function in MSDN

Is there somone that can help me with tip that describe how to get the foldername where a file was dropped to shell. I know how to drop a file to shell, but in my case i just want the name of targetfolder where file was dropped. The application that i develope (if i know the target folder) initiate a download from a SQLServer that download file(es) to targetfolder.
