GetDDB method (Main Control)
Visual Basic example
Visual C++ 4.0 example
Visual J++ example
Syntax OLE_HANDLE GetDDB (OLE_HANDLE hDC);
Overview: Refer to Copying and Creating Bitmaps.
Remarks
Converts a LEAD Technologies bitmap into a Windows device dependent bitmap (DDB). When this method is completed, there are two copies of the bitmap in memory: the DDB and the original LEAD bitmap. Freeing one will not affect the other.
Ordinarily, you would need a DDB only if you are using Windows C DLL functions. Nevertheless, for simplicity, the examples in this documentation get and set a DDB without using the C DLL.
