• Visual C# Problems with function ?

  Hi There is a problem I am facing at the moment. I have a base class called A; I have 2 classes that inherits from it . B and C. I have a method with 3 overloads . 1 for A ,1 for B and 1 for C. public void DoSomeWork(A a){} .... On calling the method It goes to the proper one by its parameter. Now, My problem is that I am using a factory to get the proper Object for a specific case and I then assign it in an A object (base class). I then want to send it to the method and expects it to go to the proper one but it goes to the one with A no matter the type returned. I always get "in A1" //Base class A1 a2 = new A2 (); //Call the proper function DoSomeWork(a1); public void DoSomeWork( A1 a ...Show All

• Visual Basic 2003 > 2005 Upgrade problem

  I have an application written in VB.Net '03 that worked fine until I attempted an upgrade. I have most of the bugs ironed out, but one I can't find a solution to: My buttons light up on MouseHover, and "unlight" on MouseLeave. This is true of all buttons, including the "exit" button. The problem is, after I click the "exit" button, the Windows Form Designer Generated Code "dispose" sub triggers the MouseLeave event, which generates an "ArgumentOutOfRange Exception because the collection the "unlit" Exit Button image is stored in is no longer available. Yikes! This didn't happen in '03 -- how do I sidestep it in '05 Is there a way to say "If the last button clicked was NOT & ...Show All

• SQL Server error when connect to sqlserver from another machine

  hi .. i install sqlserver and make app with vb6 using ADO to connect to the database and successfully i put that application on another pc on the network when i open it it says "can't login computername\guest" !! any help thanks in advance. It's hard to describe "domain controller" and related stuff in short words. I recommend you find some documents related to Windows Networks to read. Are you sure your client is running under the user account you created and you used that account to login to the server It means you may need to login the client Windows system and run your client app under that account. If you user Administrator or even logon the computer without a user/password, it won't work. ...Show All

• Visual Studio Team System WebTest recording stops working when using FileUpload control

  I was making some web tests about uploading files. I noticed that after uploading the file the recording stopped. This is the results I have managed to find out so far. As far as I can tell, the problem has to do with the FileUpload web control. As soon as the FileUpload control is hidden (MultiView, panel etc) the recording stops. If the control is hidden when you get to the page the recording will work until the FileUpload control has been displayed and once again hidden. In order to reproduce this. I made a page containing one MultiView with Two views. One button in each view and one on outside the multiview and one FileUpload placed in view2. The button in view1 just changes view to display view2 The button in view2 just ch ...Show All

• Software Development for Windows Vista Adding a service after workflow starts

  Is it possible to add the tracking or persistence service after the workflow has already started running How would you do this I believe all I need to do is get the running workflow instance and then do AddService, but that might need to be done prior to the workflow starting. Thanks! No, Persistence and Tracking services can only be to the WorkflowRuntime when it is not started. For more information take a look at the Remarks section of the AddService method found here . ...Show All

• Visual Basic Problems accessing remote registry

  Hi, I'm new to VB .NET (though I had been fairly familiar with VB 3.0 years ago). I'm trying to write a quick app to make a change to a remote registry and I can't seem to find much info on this that is consistent with how my VS .NET behaves. I've seen people making reference to code such as... regKey = RegistryKey.OpenRemoteBaseKey(RegistryHive.LocalMachine, pc).OpenSubKey(subkey) But it seems that making a call directly to "RegistryKey.Open...." is not recognized. I have to start with "Microsoft.Win32....". Perhaps a setting that I have wrong or something Or maybe I'm missing something from my project I keep getting an error stating that Win32 is not declared, but I find no reference to that error anywh ...Show All
