Hi there

I seem te be having a problem when placing images on the clipboard. It only seems to be a problem when the code is executed on a Virtual PC and I suspect it has something to do with graphics memory, but I am not sure, and I was hoping that perhaps someone will know of a better way to accomplish this.

Here is some info on the app. We have an avalon design canvas on which all kinds of objects are placed. Later on the user can then select an area of this design canvas and "grab" a bitmap image of the selection. This bitmap image is placed on the clipboard from where it can be pasted into other applications as normal images.

Here is the code that takes, as input, a FrameworkElement, makes a bitmap out of it an returns the sub-selection inside it as a bitmap image:

public static System.Drawing.Bitmap GetWin32BitmapFromUIElement(System.Windows.FrameworkElement element, System.Windows.Rect regionInsideElement)

MemoryStream fs = new MemoryStream();

System.Windows.Media.Imaging.RenderTargetBitmap bmp = element.ActualHeight > 0
new RenderTargetBitmap((int)element.ActualWidth, (int)element.ActualHeight, 1 / 96, 1 / 96, System.Windows.Media.PixelFormats.Pbgra32) :
new RenderTargetBitmap((int)element.Width, (int)element.Height, 1 / 96, 1 / 96, System.Windows.Media.PixelFormats.Pbgra32);

PngBitmapEncoder encoder = new PngBitmapEncoder();

encoder.Frames.Add(BitmapFrame.Create(bmp));

System.Drawing.Image img = System.Drawing.Image.FromStream(fs);

System.Drawing.Bitmap final = new System.Drawing.Bitmap((int)regionInsideElement.Width-1, (int)regionInsideElement.Height-1);

System.Drawing.Graphics g = System.Drawing.Graphics.FromImage(final);

g.DrawImage(img, new System.Drawing.RectangleF(0, 0, (float)regionInsideElement.Width, (float)regionInsideElement.Height), new System.Drawing.RectangleF((float)regionInsideElement.Left, (float)regionInsideElement.Top, (float)regionInsideElement.Width, (float)regionInsideElement.Height), System.Drawing.GraphicsUnit.Pixel);

return final;

}

After this, the resulting Bitmap object is placed on the clipboard:

System.Windows.Forms.Clipboard.Clear();

System.Drawing.Bitmap bmp = Utilities.GetWin32BitmapFromUIElement(this as FrameworkElement, areaToGrab);

System.Windows.Forms.Clipboard.SetImage(bmp);

bmp = null;

It is this code that causes the "Requested Clipboard Operation did not succeed" error on Virtual PCs.

Any ideas

Hi ,

Dear Friend,

I have e report file and an aspx file.

I have a textbox created inside the report file, and I want to send the value of this textbox from the aspx page. How can I do it

And how can I format a field in EURO

Thanks!!

I serialized my model doing something like this:

SerializationResult sr = new SerializationResult();

UseCaseSampleSerializationHelper.Instance.SaveModelAndDiagram(sr, obj1.ModelRoot, @"C:\TEMP\MODEL.XML", obj2.Diagram, @"c:\temp\model.diagram");

This work fine,  after i want to deserialized the model and show it on one designer, but i haven’t any file ".diagram" on the solution explorer, only I have the model load on the store:

SerializationResult sr = new SerializationResult();

UseCaseModel result=null;

Store store = new Store();

Type[] modelTypes = new Type[] {

typeof(Microsoft.VisualStudio.Modeling.Diagrams.CoreDesignSurfaceDomainModel),

typeof(Microsoft.Example.UseCases.UseCaseSampleDomainModel)

UseCaseSampleDiagram d=null;

using (Transaction t = store.TransactionManager.BeginTransaction("Reading diagram")) {

result = UseCaseSampleSerializationHelper.Instance.LoadModelAndDiagram(store, @"C:\TEMP\MODEL.XML", @"c:\temp\model.diagram", null,null);

How can i do for create a Document and show it

Thanks.
