How to display CStatic
-
I have an MFC application (VS 2003 Std). There is a dialog window with CStaticText. For example: CStatic lblRecno; I want to change the colour of the CStaticText. I am using the OnCtlColor function: HBRUSH DlgBackup::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) { HBRUSH hbr = NULL; /* if(pWnd->GetDlgCtrlID() == IDC_STATIC_LP) or */ if( nCtlColor == CTLCOLOR_STATIC ) { pDC->SetTextColor(clBlack); pDC->SetBkMode(TRANSPARENT); hbr = (HBRUSH) GetStockObject( NULL_BRUSH ); } else { hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor); } return hbr; } To this place is OK. Now I am changeing the lblRecno value in the while loop: int lp = 0; CString newTxt = ""; while(...) { ++lp; bewTxt.Format("%d", lp); lblRecno.SetWindowText(newTxt); } But the new value lblRecno is displaying in the place of the previous value, an so on. I think I should to use the WM_ERASEBKGND, but I don't know how to do it. Can you help me. Regards mwgomez Poland

What you want actually to show the static text one after another. If you just place a while loop you can see that last value only. Try with a timer updating the window text in regular intervals say 1 sec Rinu Raj
No it doesn't work. Please try it. I don't create CStatic it my sorce code, it is on the dialog window. I am setting the new Value by lblRecno.SetWindowText(...) I am setting the CStatic colour by OnCtlColor(...) and the TIMER void CDemoDlg::OnTimer(UINT nIDEvent) { lblLP.Invalidate(); CDialog::OnTimer(nIDEvent); } Regards mwgomez

inside the timer do void CDemoDlg::OnTimer(UINT nIDEvent) { static int lp = 0; CString newTxt = ""; ++lp; newTxt.Format("%d", lp); lblRecno.SetWindowText(newTxt); } then Start the timer in the initdialog Rinu Raj
I think there is steel something wrong. Please look at my source code. My dialog window is MOkno.h public: CStatic lblRecno; // for displaying recno CButton btnStart; // button Start int iLicznik; // increment variable CString newTxt; // new value of the text = iLicznik as a Text MOkno.cpp: BOOL MOkno::OnInitDialog() { CDialog::OnInitDialog(); // TODO: SetTimer(ID_TIMER1, 1000, NULL); // my Timer is running every 1 s return TRUE; } HBRUSH MOkno::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) { HBRUSH hbr; if(nCtlColor == CTLCOLOR_STATIC ) { pDC->SetBkMode(TRANSPARENT); pDC->SetTextColor(clBlue); hbr = (HBRUSH) GetStockObject( NULL_BRUSH ); } else { hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor); } return hbr; } void MOkno::OnClose() { KillTimer(ID_TIMER1); CDialog::OnClose(); } On the dialog window tehre is a Start button. When user click on the button: void MOkno::OnBnClickedButtonStart() { iLicznik = 0; newTxt = ""; // suppose: It is a database, and I am reading records // and display the current recno number for(iLicznik = 1; iLicznik <= 1000; iLicznik++) { newTxt.Format("%d", iLicznik); } } void MOkno::OnTimer(UINT nIDEvent) { CDialog::OnTimer(nIDEvent); lblRecno.SetWindowText(newTxt); } Regards mwgomez

There are some problems in your code You may modify code like this void MOkno::OnBnClickedButtonStart() { SetTimer( ...) // Set the timer here not in the oninitdialog } void MOkno::OnTimer(UINT nIDEvent) { static int i =0; newTxt.Format( "%d", ++i ); lblRecno.SetWindowText(csTex); CDialog::OnTimer(nIDEvent); } Rinu Raj

Your code is doing exactly what it is supposed to do. Paint-related messages are low priority so they do not get handled if other, high-priority messages are in the queue. This is why you do not see the
lblRecnocontrol being updated until the end. Lose the timer stuff and try:void MOkno::OnBnClickedButtonStart()
{
for(int iLicznik = 1; iLicznik <= 1000; iLicznik++)
{
CString newTxt;
newTxt.Format("%d", iLicznik);
lblRecno.SetWindowText(newTxt);
}
}I just tried this (using 10000) and it worked fine.

Of course. What are you expecting it to do? :confused:
