CRichEdit control Hyperlink color change not working

Harsh Shankar 0

I have derived a class from CRichEdit and the control contains multiple hyperlinks. While every thing works as expected, customer wants to change the color of the hyperlinks to red. I tried many things, yet the hyperlink still shows in blue color. Here is the code that fails:

for (int nLstCnt = 0; nLstCnt < nListCount; nLstCnt++)
{
    MESSAGELIST& objMsgList = m_arrMessageList[nLstCnt];
    SetSel(objMsgList.nStartPos + 1, objMsgList.nStartPos + objMsgList.strFormatString.GetLength() - 1);
    CHARFORMAT2 cf;
    memset(&cf, 0, sizeof(CHARFORMAT2));
    cf.cbSize = sizeof(CHARFORMAT2);
    cf.dwMask = CFM_LINK | CFM_COLOR;
    cf.dwEffects = CFE_LINK;
    cf.crTextColor = RGB(0xFF, 0x00, 0x00);
    SetSelectionCharFormat(cf);
}

It feels like if I use CFM_LINK, CFM_COLOR does not work. Do I am missing something? Any help will be appreciated.

Hi, is your problem solved?
The solution provided by Castorix31 worked for me.

It works for me with CFE_UNDERLINE (also bUnderlineColor for just the line color) :

Can you please share the code block. FYI, I need it to be hyperlink also since I need to do some action with the click on the link.

In fact, CFE_UNDERLINE is not needed, it depends on the order of messages.

I don't use MFC, so I tested in C++/Win32, but it is the same code.

This test adds a text "Test Link" with a link in orange to www.microsoft.com :

{
				WCHAR wsText[] = TEXT("Test Link");
				WCHAR wsTextLink[260] = TEXT("");
				wsprintf(wsTextLink, TEXT("{\\rtf1 {\\field{\\*\\fldinst{HYPERLINK \"www.microsoft.com\"}}{\\fldrslt{\\cf1\\ul %s}}}}"), wsText);

				CHARFORMAT2 cf2;
				ZeroMemory(&cf2, sizeof(cf2));
				cf2.cbSize = sizeof(cf2);
				cf2.dwMask = CFM_COLOR | CFM_LINK | CFM_BACKCOLOR ;
				cf2.dwEffects = CFE_LINK;
				cf2.crTextColor = RGB(255, 128, 0);
				cf2.crBackColor = RGB(255, 255, 255);				

				CHARRANGE cr;
				SendMessage(hWndRichEdit, EM_EXGETSEL, 0, (LPARAM)&cr);					
				SendMessage(hWndRichEdit, EM_REPLACESEL, (WPARAM)FALSE, (LPARAM)wsTextLink);
				int nRet = SendMessage(hWndRichEdit, EM_SETCHARFORMAT, (WPARAM)SCF_SELECTION, (LPARAM)&cf2);					
				cr.cpMin = cr.cpMin + (lstrlen(wsText) - 1);
				cr.cpMax = cr.cpMin;
				SendMessage(hWndRichEdit, EM_EXSETSEL, 0, (LPARAM)&cr);  	
}
