SendMessage

[hersh]

Hi,

I'm trying to use the SendMessage for sending memory stream. I did some code, but not working. Here's my code

                stream.Seek(0, SeekOrigin.Begin);
                
                int dataSize = Convert.ToInt32(stream.Length);
                byte[] byteArray = new byte[dataSize];
                int count = stream.Read(byteArray, 0, 20);
                
                while(count < stream.Length)
                {
                    byteArray[count++] = Convert.ToByte(stream.ReadByte());
                }

                IntPtr ptrData = Marshal.AllocCoTaskMem(dataSize);
                Marshal.Copy(byteArray, 0, ptrData, dataSize);

                CopyDataStruct cds = new CopyDataStruct
                { 
                  cbData = dataSize,
                  dwData = (IntPtr)1,
                  lpData = ptrData
                };
                   
                SendMessage(hWnd, WM_COPYDATA, 0, cds);

Thanks

Seems to be quite a bit of info on the internet. Try searching for "SendMessage WM_COPYDATA in C#".
