Color specific text in Edit Box

Use the following code to selectively colour text contained within a RichEdit control.


void changetextcolor(HWND hwnd,char *str,COLORREF col)
{
int lResult;
FINDTEXTEX fte; // This structure contains information about text to search for
CHARFORMAT cf; // This structure contains information about character formatting

// Set the range where to search
fte.chrg.cpMin=0; // Character position index immediately preceding the first character in the range
fte.chrg.cpMax=-1; // Character position immediately following the last character in the range

do
{
fte.lpstrText=str; // Pointer to the null-terminated string to find
// lResult=SendMessage(hwnd,(UINT)EM_FINDTEXTEX,(WPARAM)FR_DOWN,(LPARAM)&fte); // Find it
lResult=SendMessage(hwnd,(UINT)EM_FINDTEXTEX,(WPARAM)1,(LPARAM)&fte); // Find it
if(lResult!=-1) // There are more matches
{
// Set selection
if(SendMessage(hwnd,(UINT)EM_EXSETSEL,(WPARAM)0,(LPARAM)&fte.chrgText)) // Success
{
cf.cbSize=sizeof(cf);
cf.dwMask=CFM_COLOR;
cf.crTextColor=col;
SendMessage(hwnd,EM_SETCHARFORMAT,SCF_SELECTION,(LPARAM)&cf);
}
fte.chrg.cpMin=fte.chrgText.cpMax; // Set start to find more matches
}
}
while(lResult!=-1); // There are more matches
}

That's correct, a 5.
