    Common Font Dialog Box

    I have a function that displays the change font dialog box. It changes the font but not the font color interestingly MSDN tells you exactly how to do it but it doesn't work.

    Here is the MSDN link.

    http://msdn.microsoft.com/library/de...boxlibrary.asp

    Here is my code.

    font.h
    Code:
    #ifndef FONT_H
    #define FONT_H
    
    class CFont
    {
    	public:
    	    
    	    CFont();
    	    ~CFont();
    	    
    	    bool Change(HWND hParentWindow, HDC hDC, int iEditControlID);
    	    
    	    HFONT g_hFont;
    	    	    
    	private:
    	    
    	    CHOOSEFONT m_cf;
    	    
    	    LOGFONT m_lf;
    	    
    	    HFONT m_hFontPrevious;
    	    
    	    COLORREF m_rgbCurrent, m_rgbPrevious;    
    };
    
    #endif // FONT_H
    font.cpp
    Code:
    #include <windows.h>
    #include "font.h"
    
    CFont::CFont()
    {
    	
    }
    
    CFont::~CFont()
    {
    	
    }
    
    bool CFont::Change(HWND hParentWindow, HDC hDC, int iEditControlID)
    {
    	ZeroMemory(&m_cf, sizeof(m_cf));
    	
    	hDC = GetDC(hParentWindow);
    		
    	m_cf.lStructSize = sizeof(m_cf);
    	m_cf.hwndOwner = hParentWindow;
    	m_cf.lpLogFont = &m_lf;
    	m_cf.rgbColors = m_rgbCurrent;
    	m_cf.Flags = CF_SCREENFONTS | CF_EFFECTS;
    	
    	if(!ChooseFont(&m_cf))
    	{       
    		return false;        
    	}
    	
    	g_hFont = CreateFontIndirect(m_cf.lpLogFont);		
    		
    	m_hFontPrevious = (HFONT)SelectObject(hDC, g_hFont);	
    	
    	m_rgbCurrent = m_cf.rgbColors;
    	   
    	m_rgbPrevious = SetTextColor(hDC, m_rgbCurrent);	 	 
    	
    	SendDlgItemMessage(hParentWindow, iEditControlID, 
                           WM_SETFONT, (WPARAM)g_hFont, MAKELPARAM(TRUE, 0));	
    			
    	return true && g_hFont;
    }

    The font and colour are separate properties. WM_SETFONT will set the control font but you'll need to use SetTextColor to change the colour. Assuming iEditControlID is for an edit control then handle the WM_CTLCOLOREDIT (WM_CTLCOLORSTATIC for read-only edits) message and set it there. If the id is not for an edit control then you'll need to use the relevant WM_CTLCOLOR* message.

    SetTextColor() only changes the color when your are using a DC draw function like TextOut(). If you just want to change the color of static text, then handle WM_CTLCOLORSTATIC as Ken suggested.

    I'm sorta lost this is what I did and nothing happened.

    Code:
    SendMessage(hParentWindow, WM_CTLCOLOREDIT, (WPARAM)hDC, iEditControlID);
    The edit control is created as follows.

    Code:
    bool CEditControl::Create(DWORD dwStyleEx, DWORD dwStyle, int iX, int iY, 
                              int iWidth, int iHeight, HWND hParentWindow, 
                              HINSTANCE hInstance)
    {	    
    	g_hEdit = CreateWindowEx(
    	          dwStyleEx,
    	          "EDIT",
    	          NULL,
    	          dwStyle,
    	          iX,
    	          iY,
    	          iWidth,
    	          iHeight,
    	          hParentWindow,
    	          (HMENU)g_iEditControlID,
    	          hInstance,
    	          NULL
    	          );
    
         if(!g_hEdit)
         {
         	MessageBox(hParentWindow, "Can't create edit control!", "Error!",
         	           MB_ICONEXCLAMATION | MB_OK);
         	return false;
         }    
    	          
    	SendMessage(g_hEdit, WM_SETFONT, 
    	            (WPARAM)GetStockObject(DEFAULT_GUI_FONT),
    	            MAKELPARAM(TRUE, 0));
    	            
    	return true && g_hEdit && g_iEditControlID;                    
    }
    Here is the call to Font.Change
    Code:
    Font.Change(hwnd, g_hDC, EditControl.g_iEditControlID);

    The WM_CTLCOLOR* messages for controls are notifications to the parent window so you need to handle those messages, not send them. To change the text colour to, for example, red use SetTextColor as I have previously described:
    Code:
    case WM_CTLCOLOREDIT:
      {
      HDC hdc=(HDC)wParam;
      
      SetTextColor(hdc,RGB(200,0,0));
      return (LRESULT)GetStockObject(WHITE_BRUSH);
      }

    Well I got it to work now thanks. The only problem is when I handle the WM_CTLCOLOREDIT message my program ignores my manifest file.
    How can I get it to use the Windows XP visual styles now?
