SQL varbinary to bmp

Hi!!

I want to read image from SQL Server

I used these functions,but the picture is not displayed.

hstmt= DBActivateSQL (hdbc,"SELECT * FROM TABLE WHERE IMAGE_ID=30");
fromDBBits = malloc (BitsSize);

DBBindColBinary (hstmt, 4, BitsSize, fromDBBits,&bitsStatus); 

DBFetchNext(hstmt);     

NewBitmapEx (7776, 24,2592 ,1944, 0,fromDBBits,NULL,NULL,&bm );
SetCtrlBitmap (panelHandle,PANEL_PICTURE,0,bm);

please help me, thank you.
