I found another bit of simple code that worked in Beta 2 but not in rc1


c#

public partial class Window1 : System.Windows.Window
{
public Window1()
{
InitializeComponent();
Image im = new Image();
String filePath = @"c:\Program Files\Icons\sketch.JPG";
im.Source = (ImageSource)((new
ImageSourceConverter()).ConvertFromString(filePath));
MyGrid.Children.Add(im);
}
}



Whereas before this worked OK, it now causes Win32 Exception, but not when
the code above actually runs. It is specifically when the Image (or
something containing it) is first made visible and it gets rendered.

Any suggestions anyone ?

I can't seem to reproduce that. It doesn't raise an exception for me.

I guess your installation must be different to mine then.

Maybe mine's not "clean"...

Are there any known issues with installing rc1 after previous versions ? I
did a control panels uninstall of all the WinFX components from Beta 2, then
installed 3.0 from scratch.

When I drill right down with debugger I end up with a write to unauthorised
memory somewhere in a DLL called something like WindowsCodecs.

Any suggestions as to where to look ?

Thanks to Doug's hint that it was my installation at fault, I found and fixed
the problem.

My WIC (Windows Imaging Component) files and somehow ended up as the wrong
version with all the CTP's I'd had installed.

Found Robert A. Wlodarczyk's Blog (MSFT) with the fix outlined.
http://blogs.msdn.com/rwlodarc/archi...25/607131.aspx

(It refers to beta 2 but the same fix works for 3.0 rc1).

All working again.
