• Visual Studio Express Editions WeatherTracker Web Service

  Hi All, Been working my way through the book "Visual basic 2005 Express Edition: Build a Program Now!" (available as a download once registered). I've reached the last chapter where it references the Web Service for http://www.esje.com/WeatherService/Service.asmx however, this does not seem to be 'live'. Also, the service appears to be US based and I was hoping that someone can point me in the direction of another similar service which I can att ...Show All

• Windows Forms If I don't close stream, will it cause memory leak when I want to display many images?

  From MSDN, I was told that a stream couldn't be close during image lifecycle. So I can't launch stream.Close(), if I don't close stream, will it cause memory leak when I want to display many images public override void Display(ResourceData myResourceData) { MemoryStream stream=new MemoryStream(); try { byte[] myCotent=myResourceData.content; stream.Write(myCotent,0,myCotent.Length); stream.Position=0; PictureBox1.Image=Image.FromStream(strea ...Show All

• Windows Forms Better design-time support for custom objects in collections

  I think one of the biggest weaknesses in the WinForms (and ASP.NET, for that matter) design-time story is the lack of support for adding your own custom objects to designed collections. For instance, I once wrote a MenuItem class that could be  ...Show All

• Visual Studio Team System Team System Builds and dropping an MSI

  Hi, I just started using Team System this week, and I've been able to muddle along fairly well, but I've just discovered something that to me is a real show stopper. And based on the searches that I have done in Google and in these forums, I'm beginning to think there is something fundamental I missing based on the small number of responses to this problem. My problem is that the team system build does not build the Setup projects ...Show All

• .NET Development Storing ConnectionString in app.config

  Hi, I'm sure I'm missing something really obvious here, but I can't see it!!  I have a Data Access Layer project (DLL) which contains a typed dataset (just containing stored procedures - no DataTables).  This is fine, and does what I want  except the connection string is stored in the Project Settings. My problem with that is the DAL is used from different WinForm projects which may require a different connection string (tw ...Show All

• Visual Basic How to instance a class in the current project

  Hey NG So, the subject says everything - I think. I have a MDI-Application. In one of my ChildForms I have some UserControls. By changing the CheckedEvent of a RadioButton(in the Form), my class enables or disables all TextBoxes of the UserControls. - Therefor I use ReadOnly Property to access the status. But I do need the status also in the UserControls. I don't want to check the RadioButton - I don't think that is the correct way.  - Beca ...Show All

• Visual Basic Validating within a User Class

  I need to populate a container with an indeterminate number of label/textbox pairs for input. Since it is indeterminate at design time, I thought I'd create a user class with both a label and at text box in a pair so I could create them at run time and populate the labels appropriately from a data file. I need to validate each text box for numeric value. Then, I need to use that value to build up a subtotal on the form...sort of like this: ...Show All

• Windows Forms ContainerControl inside another ContainerControl

  <.NETFramework> I am facing problems using a ContainerControl inside another ContainerControl. The child ContainerControl is not getting on the design surface probably. I'm not being able to drop any control (e.g a Button) on the inner ContainerControl. It is dropping the control (Button) on the outer ContainerControl instead. I know there is something like EnableDesignMode in Framewrok 2.0. But I cannot find it in Framewrok 1.1. I w ...Show All
