}按照MSDN的要求,先在Dialog Box上画一个edit,然后设置其变量为Control 并且为CYellowEdit类型令问: ON_WM_CTLCOLOR_REFLECT() 干吗的?附MSDN的示例To try the example that creates a reusable control
Create a new dialog box in an existing application. For more information, see the dialog editor topic. You must have an application in which to develop the reusable control. If you don't have an existing application to use, create a dialog-based application using AppWizard. With your project loaded into Visual C++, use ClassWizard to create a new class called CYellowEdit based on CEdit.Add three member variables to your CYellowEdit class. The first two will be COLORREF variables to hold the text color and the background color. The third will be a CBrush object that will hold the brush for painting the background. The CBrush object allows you to create the brush once, merely referencing it after that, and to destroy the brush automatically when the CYellowEdit control is destroyed.Initialize the member variables by writing the constructor as follows: Copy Code
CYellowEdit::CYellowEdit()
{
m_clrText = RGB( 0, 0, 0 );
m_clrBkgnd = RGB( 255, 255, 0 );
m_brBkgnd.CreateSolidBrush( m_clrBkgnd );
}
Using ClassWizard, add a handler for the reflected WM_CTLCOLOR message to your CYellowEdit class. Note that the equal sign in front of the message name in the list of messages you can handle indicates that the message is reflected. This is described in Defining a Message Handler for a Reflected Message. ClassWizard adds the following message-map macro and skeleton function for you: Copy Code
ON_WM_CTLCOLOR_REFLECT()// Note: other code will be in between....HBRUSH CYellowEdit::CtlColor(CDC* pDC, UINT nCtlColor)
{
// TODO: Change any attributes of the DC here
// TODO: Return a non-NULL brush if the
// parent's handler should not be called
return NULL;
}
Replace the body of the function with the following code. The code specifies the text color, the text background color, and the background color for rest of the control. Copy Code
pDC->SetTextColor( m_clrText ); // text
pDC->SetBkColor( m_clrBkgnd ); // text bkgnd
return m_brBkgnd; // ctl bkgnd
Create an edit control in your dialog box, then attach it to a member variable by double-clicking the edit control while holding a control key down. In the Add Member Variable dialog box, finish the variable name and choose "Control" for the category, then "CYellowEdit" for the variable type. Don't forget to set the tab order in the dialog box. Also, be sure to include the header file for the CYellowEdit control in your dialog box's header file.Build and run your application. The edit control will have a yellow background.感激不尽啦~~~~~~~~~~~~~~~~~~~~~~~~~~~ 只剩20分了
