If you're using CrystalReportViewer object to show the report, try wiring CrystalReportViewer.Error and CrystalReportViewer.HandleException events. They should give you more info what goes wrong.

The need to optimize rises from a bad design

Are you sure that a new path is being sent to the method? If you attempt to ovewrite the open file you can get this message. If a new path is being set, check that your program has write permissions on it.

Try not disposing of anything, and see if it works. I have had problems closing streams in a similar scenario. If it works, try wrapping the disposable objects in using blocks instead (which strangely seemed to work in my case).

Does the error occur on the Save() call?

You must copy all the dlls that are in the same folder as the executable.

foreach (Node ndSource in treeSource.Nodes)

    newNode.Text = ndSource.Text;
    -- copy all required properties like the text property above --
    ChildNodes(ndSource, newNode);
    treeDestination.Nodes.Add(newNode);
}

private void ChildNodes(Node ParentNode, Node newParent)
{
    foreach (Node ndChild in ParentNode.Nodes)

        Node newNode = new Node();
        newNode.Text = ndChild.Text;

A node can't exist in two treevies at once. Each node has to be cloned first so some sort of loop is inevitable. Two code snippets below. The first does what you want but with a loop. The second moves the nodes rather than copies but no loop required.

// Copies the nodes
if (treeView1.Nodes.Count > 0)
{
    TreeNodeCollection treeNodes = treeView1.Nodes;
    TreeNode[] nodearray = new TreeNode[treeNodes.Count];
    for (int i = 0; i < nodearray.Length; i++)
    {
        nodearray[i] = (TreeNode)treeNodes[i].Clone();
    }
    treeView2.Nodes.AddRange(nodearray);
}

//Moves the nodes
if (treeView1.Nodes.Count > 0)
{
    TreeNodeCollection treeNodes = treeView1.Nodes;
    TreeNode[] nodearray = new TreeNode[treeNodes.Count];
    treeNodes.CopyTo(nodearray, 0);
    //Clear the original tree as nodes can't exist in both
    treeView1.Nodes.Clear();
    treeView2.Nodes.AddRange(nodearray);
}

how to monitor WCF/web services traffic?

Hello everyone,

I want to monitor the WCF/web services communication between client and server to serve better debugging purpose.

Any tools? I could use sniffer, but not quite friendly to show SOAP message format.

thanks in advance,
George

With .NET 2.0 you could use a feature in WSE3 that was tracing SOAP traffic between server and client. Myself, I use a third party program called HttpAnalyzer which served me well.

Thanks blackjack2150,

1.

To use WSE3, I think it is an SDK, and we need to write code, correct (i.e. not a ready to use tool)?

2.

I made some study for HttpAnalyzer, looks like a sniffer tool for Http traffic, similar to Microsoft Fiddler2? Smile | :)

George

Smart device screen resolution

Hi there,

I have written a c# application (VS2005) for a windows CE 5.0 device (Psion 8515) with a screen/res
of 6.4", 640 x 480.
I had to make chunky controls on the forms for the tractor drivers to be able to touch screen easaly without using a stylus.
I now need to load the same application on a much smaller Pocket PC (Psion workabout
Display 3.5" Resolution: 240 x 320) without having to redesign all the forms, buttons etc...
The application runs fine on the Workabout but does not automatically resize the forms and controls.
I end up with a scrolling screen.
Never did that before, does anyone have a solution, direction to take?
Very much appreciated
Thanks
Scalpa

I want to insert an image in the header of the WORD document through C#. The word document initially gets created through code only. When I try to access "oWordApplic.Selection.HeaderFooter", it shows "null". Not sure how to create a HeaderFooter object and insert an image into it.

private Word.ApplicationClass oWordApplic;
oWordApplic = new Word.ApplicationClass();
