更新:

我正在尝试像这样设置文本颜色.

I'm trying to set the text color like this.

SendMessage(hEdit, EM_SETSEL, start_pos, end_pos); //select text for coloring

        CHARFORMAT cf;
        memset( &cf, 0, sizeof cf );
        cf.cbSize = sizeof cf;
        cf.dwMask = CFM_COLOR;
        cf.crTextColor = RGB(255,0,0);
        SendMessage( hEdit , EM_SETCHARFORMAT, SCF_SELECTION, (LPARAM) &cf);

        SendMessage(hEdit, EM_SETSEL, -1, 0 ); //deselect text
        cf.crTextColor = RGB(0,0,0); //reset colour
        SendMessage( hEdit , EM_SETCHARFORMAT, SCF_SELECTION, (LPARAM) &cf); //set colour

推荐答案

你的问题很不清楚.疯狂尝试:当您分配 Text 属性时，您会丢失所有格式.请务必改用 AppendText().并将 SelectionColor 和 SelectionBackColor 属性设置回为任何文本着色后的状态，以便新输入的文本获得首选的默认颜色.

Your question is quite unclear. Wild stab at it: you lose all formatting when you assign the Text property. Be sure to use AppendText() instead. And to set the SelectionColor and SelectionBackColor properties back to what it was after colorizing any text so that newly entered text gets the preferred default colors.
