If rewritten properly this method is tail-recursive and thus ipso facto iterative (by nature).

I don't completely understand your answer. Yes, I want my browser to auto-complete the username and password boxes. chrome can do this. when logging in to a site, protected with form authentication. chrome will suggest you to save the credentials that you have used to authenticate. The next time when you visit the site, both fields are filled in automatically by the browser. << Nearly all men can stand adversity, but if you want to test a man's character, give him power. >>

No, unfortunately, static classes must derive from Object and nothing else, and neither interfaces or abstract classes can be static anyway. It's hard to comment on your design without seeing the whole thing, but I would suggest that yes, to have static classes representing business entities is a bit of a strange design. Again, it's hard to suggest alternatives without seeing everything you are trying to do, but a pretty standard way is to have a bunch of business objects that define your business entities, these can then be created 1 for each entity and store all the values, and can possibly inherit from a base entity object.

I want the tree not to be selected, not expanded. so when the tree is displayed, a postback is generated, as if the user clicked on the node itself to select it. << Nearly all men can stand adversity, but if you want to test a man's character, give him power. >>

hello, Thanks for your answer. found some other http://forums.asp.net/p/945319/1145830.aspx[^] only cookie ASP.NET_SessionId needs to be replaced. for the moment, can't get this to work correctly... << Nearly all men can stand adversity, but if you want to test a man's character, give him power. >>

NikoTanghe wrote: Process.start() simply returns, no program is launched, no exception is thrown... what is wrong here ? The problem is you don't understand how services work. Services run under their own desktop, NOT the users desktop that you can see. The Process.Start() code worked. The application was launched. All you have to do is open TaskManager and click on the Processes tab to see that. You have to configure your service to interact with the users desktop. Click Start/Run, then type SERVICES.MSC and hit enter. Find your service in the list and double-click it. Click on the LogOn tab and find the little check box that says something like "Allow server to interact with desktop" and enable it. Now, YOU HAVE A MUCH BIGGER PROBLEM. Services run all the time, even when noone is logged into the machine. So, with no user desktop to show an app, you're service will still launch the applications, but noone will ever see them because there is no user desktop! Just logging into the machine will NOT automatically show you the launched applications either. They will be running, but on the services desktop only. There is no way to transfer the application between desktops. In order for the logged in user to see them, the applications would have to be killed and restarted. Notice, in the .NET Framework's Service classes, that you don't get any "User logged on" events...

No. Perhaps you can base64 encode the data? led mike

For accessing a .net component from palin c++(unmanaged)you have to use CCW com callable wrapper. For this, if the .net component is already written in such a way that it be used for generating the ccw, directly use it. or else write a managed c++/c# wrapper which is compliant with requirements fo a CCW. then use the ccw from plain c++ cheers...milton kb

Agreed. Please call DataRow.Delete() instead.

You could hack the change by creating your own derived class from TabControl and just monitor the SelectedIndexChanged event. The following code will prevent a user from selecting the third tab in the MyTabControl class. using System; using System.Windows.Forms; namespace WindowsApplication1 { public class MyTabControl : TabControl { private int lastSelectedIndex = 0; public MyTabControl() : base() { lastSelectedIndex = this.SelectedIndex; this.SelectedIndexChanged += new EventHandler( SelectedIndexChanged ); } private void SelectedIndexChanged( object sender, EventArgs e ) { // Prevent someone from choosing TabPage number 3. if( this.SelectedIndex == 2 ) { this.SelectedIndex = lastSelectedIndex; } else { lastSelectedIndex = this.SelectedIndex; } } } } "we must lose precision to make significant statements about complex systems." -deKorvin on uncertainty

I am indeed using the com object internally. The object is created and used within a single webmethod. I am accessing the com object by using a com interop (created by add reference...) Why am I getting this AccessDenied error? Is it somehow possible to access the registry and the file system from within a webservice?

making a usercontrol of the panel would make sense, I'll try this one. There nothing much to see on the panel to edit a product: About 10 databound text boxes and 2 editable datagrids are on the panel Kurt, thanks for you advice.

Override CreateParams in your derivative class and set the CreateParams.ClassName. If this is not an existing Window class, you'll need to P/Invoke RegisterClassEx and call it prior to creating any instances of your new control class. See http://pinvoke.net/default.aspx/user32.RegisterClassEx[^] for more information. This posting is provided "AS IS" with no warranties, and confers no rights.

Override the WndProc message of your main form and evaluate the Message.Msg property. Example: protected override void WndProc(ref Message m) { if (m.Msg == 0x001C) { // Caught the WM_ACTIVATEAPP message } base.WndProc(m); } www.troschuetz.de
