Practical, remember.1, find the appropriate bitmap on the Internet, and add bitmap resources, such as named Idb_back1;2, insert the dialog box, first drag and drop the control;3. Add two variables, bitmap variables and brush variables in the dialog class:CBitmap M_bmback;CBrush M_brback;This is declared as a class member in order to avoid the case where the local variable is destroyed after the function has finished running.4. Load bitmap resources and bit drawing brushes in OnInitDialog:...M_bm

Label:As far as I know, Apex 4.x does not provide an editable interactive reporting component. This requires our manual implementation. In fact, this is not very complicated, just a few simple steps.1. Create a interactive report according to the wizard. The query statement can be as follows.

. Setbkmode is used to adjust the bkcolor ing mode. The default value is opaque. This mode uses the current text background color (set by setbkcolor) when you draw text on the control interface, if setbkcolor is not used, the background color of the entire control is set by default. This background color is specified when a subwindow is created, rather than the image brush returned by onctlcolor.) Click it again and then draw the text. Another ing mode is transparent.

In a dialog box-based program, a task is to change the background of the edit box control. What should I do? The implementation idea is as follows. When the child control is to be drawn, wm_ctlcolor will be sent to the parent class (the main window here) Message. In the parent class (here is the main window), the response wm_ctlcolor is sent based on the message. The specific code is as follows: CBrush m_brush; m_brush.CreateSolidBrush(RGB(0, 0, 255)); HBRUSH CMy112Dlg::OnCtlColor(CDC* pDC, C
