I send the file in parts. Then I join them again. But i doesn't work. I
think I did it too simple
here is my code:
BYTE tBuffer[100];
TJPEGImage *tjp = new TJPEGImage();
TMemoryStream* tpms = new TMemoryStream();
//--------------------------------------------------------------------------
-
void __fastcall TfMain::wmImagenClick(TObject *Sender)
{
BYTE Buffer[100];
int pos = 0;
OpenPictureDialog->FileName = GraphicFileMask(__classid(TJPEGImage));
if (OpenPictureDialog->Execute())
{
TJPEGImage *jp = new TJPEGImage();
TMemoryStream* pms = new TMemoryStream();
jp->LoadFromFile(OpenPictureDialog->FileName);
jp->SaveToStream(pms);
while(pos < pms->Size - 100)
{
pms->Seek(pos, soFromBeginning);
pms->ReadBuffer(Buffer, 100);
ClientSocket->Socket->SendBuf(Buffer, 100);
pos += 100;
}
pms->Seek(pos, soFromBeginning);
pms->ReadBuffer(Buffer, pms->Size - pos);
ClientSocket->Socket->SendBuf(Buffer, pms->Size - pos);
}
}
//--------------------------------------------------------------------------
-
void __fastcall TfMain::ServerSocketClientRead(TObject *Sender,
TCustomWinSocket *Socket)
{
int total = Socket->ReceiveLength(), recived, newpacketsize;
recived = tpms->Size;
if(total - recived > 100)
newpacketsize = 100;
else
newpacketsize = total - recived;
Socket->ReceiveBuf(tBuffer, newpacketsize);
tpms->WriteBuffer(tBuffer, newpacketsize);
if(tpms->Size == total)
{
tjp->LoadFromStream(tpms);
PaintBox->Canvas->Draw(0,0,tjp);
}
}
//--------------------------------------------------------------------------
