Change color of static/edit using: SetTextColor and SetBkMode

[r0n]

I noticed when using "DT_SetTextColor" the dialog is refreshed completely thus giving that short redraw effect (at least in my dialog).

My dialog is a folder browser using a listbox, certain filetypes get colored differently (rtf = purple, txt=black, doc=blue ,....)
The problem is that every time a file-item is clicked within the listbox the whole dialog refreshes (you can see the dialog refresh itself, it's very fast but still noticeable)

I cloned the items within "DT_SetTextColor" and then disabled the last line:
if(IsWindowVisible(hDlg)) InvalidateRect hDlg 0 1

And then it all worked without the refresh effect.

But for now I wanted know how to use "SetTextColor and SetBkMode" in the below example.
Using "SetTextColor and SetBkMode" I could then decide how to do the refresh if it's still needed.
Probably this should work also then: RedrawWindow(###CONTROL_ID### 0 0 RDW_INVALIDATE)

What I have below doesn't work but any example of how to do it is greatly appreciated.
(I have a way of doing this with the background color, there are examples of that ,but I can't get the textcolor method working...)

(The editfield and static needs to change color on buttonpress.)

Function change_txt_color_on_buttonpress

This seems to work but is it possible to preserve the transparency of the static control?

for the static control don't return t_hbrush
instead use

Code:

Copy      Help

ret GetStockObject(NULL_BRUSH)

i edited your code a little removed unneeded parts

Thanks!!!

[Kevin]

after taking another look at this 

these lines can be eliminated
__GdiHandle- t_hbrush
int backcolor_at_start=0xffffff
,t_hbrush=CreateSolidBrush(backcolor_at_start)

and instead use 

Code:

Copy      Help

ret GetStockObject(DC_BRUSH)

for the edit control
