See more:

I have a source file called RoundBtn.cpp with its header file RoundBtn.h

these two files are responsable for coloring the entier buttons on my Dialog. What i need to do is to give one of my button a special color. Some of the code for coloring all buttons is given below.

void RoundBtn::DrawItem(LPDRAWITEMSTRUCT lp)
{
	CRect rc = lp->rcItem;
	CDC dc;
	dc.Attach(lp->hDC);
	dc.SetBkMode(TRANSPARENT);
	CBrush br;
	br.CreateStockObject(NULL_BRUSH);
	dc.SelectObject(&br);
	if (is_pressed) // when the button is pressed
	{
		CPen pen(PS_SOLID, 2, RGB(0,0,0));
		dc.SelectObject(&pen);
		CBrush *pBrush=new CBrush(RGB(220,100,220));
		dc.SelectObject(pBrush);
		dc.RoundRect(0, 0, rc.Width(), rc.Height(), rc.Height()/1, rc.Height()/1);  // Round the Buttons 
		dc.SetTextColor(RGB(0, 0, 0));

What I have tried:

What sould i change on my main file or what sould i call on my main file to color the button. the button ID Adress is

IDM_APPLY

and its function is

void CVCDlg::Apply1()
{

OnButtonApplyrange(); 

}

Solution 1

The color used to construct the *pBrush is the one that needs to be adjusted. You could make a color variable (COLORREF) a member of the RoundBtn class and set it to 220,100,220 in the class constructor. Then add a method to set the color member and you can have each button be a different color if you wanted to.

I added this to my RoundBtn.cpp file

void RoundBtn::SetColor(COLORREF text, COLORREF bkgnd)
{
m_TextColor = text;
m_BkgndColor = bkgnd;

if(m_hWnd != NULL)
Invalidate();
}

then I added this to my RoundBth.h

COLORREF m_TextColor;
COLORREF m_BkgndColor;

and this

void SetColor(COLORREF text, COLORREF bkgnd);

then i added this to my main file

Loadbt1.SetColor(RGB(255,255,255),RGB(255,255,255));

where Loadbt1 is the button that i want to color

it shows no error but it still does not work

You forgot some changes in DrawItem - instead of using RGB(220,100,220) :

CBrush *pBrush=new CBrush( m_BkgndColor );

and change the SetTextColor call also to :

dc.SetTextColor( m_TextColor );

BTW, white is probably not the best color to use for both the text and the background.
