The MFC class library providesCwnd::OnctlcolorFunction. This member function is called when the child window of the working framework is re-painted.Wm_ctlcolorMessage response function. prototype of this function:Afx_msg hbrush onctlcolor (CDC * PDC, cwnd* Pwnd, uint nctlcolor ); ParametersNctlcolor Used to specify the control type, which can be:.

Recently, when I made a checkbox transparent, I encountered a cbutton re-painting. There were many posts on the Internet about this problem and there were many implementation methods. Here we will only talk about some problems and solutions I have encountered in actual operations. 1. When the wm_ctlcolor is reloaded in the form to achieve transparency, in some systems that use the XP style, the checkbox has a dark background color and does not really achieve the transparency effect, the specific

Rewrite function onctlcolor () // Change the button colorHbrush cdialogdrawdlg: onctlcolor (CDC * PDC, cwnd * pwnd, uint nctlcolor){Hbrush HBr = cdialog: onctlcolor (PDC, pwnd, nctlcolor );//If (pwnd-> getdlgctrlid () = idok | pwnd-> getdlgctrlid () = idcancel){PDC-> settextcolor (RGB (, 0, 0); // you can specify the te

LoadBitmap (IDB_BITMAP_TEMPBK); M_brushbk.createpatternbrush (bmp); M_brushbk.createsolidbrush (RGB (0,255,0)); Use solid color as background Bmp. DeleteObject (); 3. Return background brush in OnCtlColor function Hbrush Cxxxxxdlg::onctlcolor (

Here are three ways to implement the default background color for changing dialog boxes: (1) You can set the background color of the update dialog box in Clotteryapp::initinstance () Call SetDialogBkColor (RGB (160,32,240)) That is, you can change the background color Note that the color drawn here is for all dialog boxes in the program SetDialogBkColor (RGB (0,0,255), RGB (255,0,0)); Previous RGB is the background color, the latter RGB is the text colors (2) You can also clotteryd

The MFC Class Library provides the Cwnd::onctlcolor function, which is called when the child window of the working frame is redrawn. Therefore, you can overload the response function of the wm_ctlcolor message. The prototype of this function:afx_msg hbrush OnCtlColor (CDC *pdc,cwnd *pwnd,uint nCtlColor);The parameter nctlcolor is used to specify the type of control, which can be:. ctlcolor_btn Button controls. ctlcolor_dlg dialog box. Ctlcolor_ edit box. ctlcolor_listbox List control. ctlcolor_m

Overrider onctlcolor for wm_ctlcolor for your dialog like following to Set background and text color: E.g. Hbrush cmydlg: onctlcolor (CDC * PDC, cwnd * pwnd, uint nctlcolor){Hbrush HBr = cdialog: onctlcolor (PDC, pwnd, nctlcolor );If (pwnd-> m_hwnd = getdlgitem (idc_text)-> m_hwnd) // use static ID of your static text Control{PDC-> setbkcolor (RGB (255, 0, 0); // red backgroundPDC> settextcolor (RGB (255,255,255); // white textReturn

discarded, what is it instead?The WM_CTLCOLOR message is used to complete setting the background and font color for controls such as edit, STATIC, button,Automatic generation of the OnCtlColor () function using the Class wizardThis function sets the desired color and then returns a brush handle to redraw the control background color. The onctlcolor () function handles the control's background color by capturing the corresponding control message. Common types of such messages are:ctlcolor_dlg di

As far as I know. Apex 4.x is not provided with an editable interactive reporting component. This needs to be implemented manually.In fact, this is not very complicated, just a few simple steps.1. Create a interactive report based on the wizard. Query statements can be as follows. Select Apex_item.hidden (1,e.id) | | E.name as Staff, Apex_item.select_list_from_lov (p_idx=>2,p_value=>e.department_id,p_lov=> ' lov_department ') as department from employee E; The key here
