各位大大你們好!!
我目前是做ccd擷取畫面，但我現在想要利用mdi的方式去把畫面顯示再另一個視窗上面(只用一個form可以顯示畫面了)，
請問要怎麼寫，我寫的方式有錯，可以跟我提供意見!!!!
以下是我的程式碼 (p.s.我算是剛完這個，拜託)
//第一段 Form1
//---------------------------------------------------------------
void __fastcall TForm1::OnFormPaint(TObject *Sender)
{
TForm2 *Form2;
// Protection
if (m_pCurrent==NULL) return;
// Get DC of the window
HDC hDevice = GetDC (Handle);
// Display picture
SetDIBitsToDevice (hDevice, i, j, m_SizeX, m_SizeY,
0, 0, 0, m_SizeY,
m_pCurrent, m_pBitmapInfo, DIB_RGB_COLORS);
// Release DC
ReleaseDC(Handle,hDevice);
// Display channel info on status bar
// Retrieve the channel state
McGetParamInt (m_Channel, MC_ChannelState, &m_ChannelState);
// Retrieve the frame rate
double frameRate_Hz;
McGetParamFloat(m_Channel, MC_PerSecond_Fr, &frameRate_Hz);
// Display frame rate and channel state
StatusBar1->SimpleText = m_StatusBarText.sprintf("Frame Rate: %.2f, Channel State: %s", frameRate_Hz,
(m_ChannelState == MC_ChannelState_ACTIVE? "ACTIVE" : "NOT ACTIVE"));
}
//---------------------------------------------------------------------------
void WINAPI GlobalCallback (PMCSIGNALINFO SigInfo)
{
TForm2 *Form2;
if (SigInfo && SigInfo->Context)
{
TForm1* pTForm1 = (TForm1*) SigInfo->Context ;
pTForm1->Callback (SigInfo);
}
}
//---------------------------------------------------------------------------
void TForm1::Callback(PMCSIGNALINFO SigInfo)
{
TForm2 *Form2;
if (SigInfo->Signal == MC_SIG_SURFACE_PROCESSING)
{
// Update "current" surface address pointer
McGetParamInt (SigInfo->SignalInfo, MC_SurfaceAddr, (PINT32) &m_pCurrent);
// Post screen refresh message
RECT recpict ;
recpict.left =0;
recpict.top =0;
recpict.right = m_SizeX-1;
recpict.bottom = m_SizeY -1;
InvalidateRect(Handle,&recpict,false);
}
else if (SigInfo->Signal == MC_SIG_SURFACE_PROCESSING)
{
// Insert your failure handling code here.
}
}
//第二段 Form2
//------------------------------------------------------------
// Post screen refresh message
RECT recpict ;
recpict.left =0;
recpict.top =0;
recpict.right = m_SizeX-1;
recpict.bottom = m_SizeY -1;
InvalidateRect(Handle,&recpict,false);
}
else if (SigInfo->Signal == MC_SIG_SURFACE_PROCESSING)
{
// Insert your failure handling code here.
}
}
