Windows 7 TextureBrush..ctor() error

Question

I have a .NET 2.0 app that runs just fine on XP and Vista, but on Windows 7 RC (x64) it crashes with the following error:

Exception Information

---

Exception Type: System.OutOfMemoryException Message: Out of memory. Data: System.Collections.ListDictionaryInternal TargetSite: Void .ctor(System.Drawing.Image, System.Drawing.Drawing2D.WrapMode) HelpLink: NULL Source: System.Drawing

StackTrace Information

at System.Drawing.TextureBrush..ctor(Image image, WrapMode wrapMode) at System.Windows.Forms.ControlPaint.DrawBackgroundImage(Graphics g, Image backgroundImage, Color backColor, ImageLayout backgroundImageLayout, Rectangle bounds, Rectangle clipRect, Point scrollOffset, RightToLeft rightToLeft) at System.Windows.Forms.Control.PaintBackground(PaintEventArgs e, Rectangle rectangle, Color backColor, Point scrollOffset) at System.Windows.Forms.Control.PaintBackground(PaintEventArgs e, Rectangle rectangle) at System.Windows.Forms.Control.OnPaintBackground(PaintEventArgs pevent) at System.Windows.Forms.ScrollableControl.OnPaintBackground(PaintEventArgs e) at System.Windows.Forms.Control.PaintWithErrorHandling(PaintEventArgs e, Int16 layer, Boolean disposeEventArgs) at System.Windows.Forms.Control.WmPaint(Message& m) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ScrollableControl.WndProc(Message& m)

Any ideas about why this is happening, or how I might program around it? It's just painting a standard winform with no special background.

UPDATE: I've found that this is only an issue when the BackgroundImageLayout = ImageLayout.Tile, which is also the default. Set it to Zoom or Center, and the issue dissapears. That's pretty unsatisfactory though, because I need it to tile.

I had a similar problem. In my case I had disposed of my MemoryStream I loaded the image from.

//The following throws and OutOfMemoryException at the TextureBrush.ctor():

    /*someBytes and g declared somewhere up here*/
    Bitmap myBmp = null;
    using(MemoryStream ms = new MemoryStream(someBytes))
       myBmp = new Bitmap(ms);

    if(myBmp != null) //that's right it's not null.
       using(TextureBrush tb = new TextureBrush(myBmp)) //OutOfMemoryException thrown
          g.FillRectangle(tb,0,0,50,50);

//This code does not throw the same error:

    /*someBytes and g declared somewhere up here*/
        MemoryStream ms = new MemoryStream(someBytes);
        Bitmap myBmp = new Bitmap(ms);

        if(myBmp != null)
           using(TextureBrush tb = new TextureBrush(myBmp))
              g.FillRectangle(tb,0,0,50,50);

Turns out the solution to this had to do with the PNG file itself used for the background. I just opened it with Paint.NET and resaved it, then put it back in the project and it worked.

Not sure what changed, but it resolved the problem.
