hi

i can change color with


HWND dh = FindWindow("ProgMan",0);
dh=GetWindow(dh,GW_CHILD);
dh=GetWindow(dh,GW_CHILD);
ListView_SetTextBkColor(dh, CLR_NONE); // icon background to transparent
ListView_SetTextColor (dh, RGB(0,255,0)); // icon text color to rgb()
ListView_RedrawItems (dh, 0, ListView_GetItemCount(dh) - 1); // redraw all icons


everything works fine, but icon background and text color gets back to normal when i refresh desktop(F5), is there a way to change it permanent. Any registry entry where that color is stored?
my program closes itself when it gets the job done, so i cant monitor for desktop refresh and change color then.

Are you sure that only that "Refresh" command will restore original color?
Anyway, with a help from Spy++ you can see that refresh sends WM_USER+3152 message to the list view.
Now you "only" need to somehow hook into that list's window proc and monitor that message :)
But if you can hook into it - you might also hook into its parent and handle the custom draw messages.
But why would you want to change that color?

How are you setting the icons? Are you using an imagelist? If so, are you using ILC_MASK with ILC_COLOR32 or ILC_COLOR24?

my wallpaper changes every few hours, and i want black icon font color on light wallpaper and
white font on dark one ^^ ofc. drop shadow is disabled

second thoughts: i will probably stick with drop shadow for now(su.x hard on white background), cause i never played with hooks and dont have much time now

Oops. For some reason I thought you were dealing with a ListCtrl. I must have confused this with another thread. Sorry.
