Question

I am trying to get the current Windows theme name in C# but it has turned out to be a little tougher than expected. I have a code sample from MSDN:

public void Test() {     StringBuilder themeFileName = new StringBuilder(0x200);     GetCurrentThemeName(themeFileName, themeFileName.Capacity, null, 0, null, 0);     string fileName = Path.GetFileName(VisualStyleInformation.ThemeFilename);     if (string.Equals('aero.msstyles', fileName, StringComparison.OrdinalIgnoreCase))     {         // user is using aero theme     } }  [DllImport('uxtheme.dll', CharSet = CharSet.Auto)] public static extern int GetCurrentThemeName(StringBuilder pszThemeFileName, int        dwMaxNameChars, StringBuilder pszColorBuff, int dwMaxColorChars,     StringBuilder pszSizeBuff, int cchMaxSizeChars); 

GetCurrentTheme() does not modify the StringBuilder. I also tried looking at the
System.Windows.Forms.VisualStyles.VisualStyleInformation class, but it is full of empty values. Anyone know how to do this? I must be missing something easy, but I haven’t found anything yet that works.

Answer 1

That article on CodeProject describes how to get ‘the current visual style information’ (search for that string in the article).

It contains sample code how to do that.
