Hi all

Hi Hiroaki

Yes, I'm coding in C#. The 'OpenThemeData' is succeeded and gives me a
correct theme handler that i use nice with any theme-specific functions.
Also GetThemeSysColo r is working correctly.
Below is my declaration:

[DllImport("uxth eme.dll", CharSet=CharSet .Auto)]
private static extern int GetThemeColor(i nt hTheme,int Part,int State,int
iColorID,ref int ColorRef);

PS: I tried to pass WINDOW as control part with different states and color
with no successful result.
As a result I am receiving always error "element not found".
PS1: If you know any correct template when this call succeeded please post
it here.

Thank you
Yuri

The api looks correct. What are you passing for the iColorID? e.g. For the
border color, you'd use 3801.

Hi Andrew

Thanks for reply. Sure, i use constants from <tmschema.h>.
But nothing works yet. Amazing :)

PS: below is my prosedure:
---------------------------
internal static Color GetThemeColor(C ontrolPart part, ControlState state,
int iColorID)
{
int result;
int theme ;
// Check to make sure the current system supports themes
if (!SupportsTheme s)
throw (new PlatformNotSupp ortedException( "This system does not support the
use of themes."));
// Get the active Windows XP theme for the specified type of control
Themes.ControlC lass cp= ControlPartClas ses[(int)part];
string s= ControlClassNam es[(int)cp];
theme = OpenThemeData(H andleTemp, s); // "WINDOWS"
if (theme == 0)
throw (new NullReferenceEx ception("No active Windows XP Theme could be
detected."));
int ColorRef= new Int32();
result= GetThemeColor(t heme, (int) part, (int) state, iColorID, ref
ColorRef);
Color cr= Color.White;
if(ColorRef!=0)
cr=ColorTransla tor.FromWin32(C olorRef);

result = CloseThemeData( theme);
if (result != 0)
throw (new InvalidOperatio nException("The call to CloseThemeData failed with
an error code of " + result.ToString () + "."));
return cr;
}

Hi yuri

[DllImport("uxth eme.dll", CharSet=CharSet .Auto)]

It's seems correct, but would you try this?

private static extern int OpenThemeData (System.IntPtr hwnd,
[In,MarshalAs(Un managedType.LPW Str)] string pszClassList);

Actually now that I look at it, I think you should remove the CharSet from
the api declaration - that is exported as GetThemeColor and not
GetThemeColorA/GetThemeColorW.

BTW, why do you assume that if the colorref is 0 that it is white -
shouldn't it be black?

Hi Hiroaki

It's solved. The problem was not in procedure.
The real reason that not each color defined has an equal real color stated
in theme metric.
As the result most calls returns error code and I by mistake assumed it as
trouble with procedure. In fact a several colors is stated only for such
complicated object as a windows so if we ask color e.g. EDGESHADOWCOLOR and
a couple of others then it works :-)

Thanks for your assistance so much.
Thanks
