• santosh.kulkarni TextBox Input Validation

  Greetings: I'm trying to get a textbox to only accept the input of numbers, ".", and the back key. I modeled this on the example in the MSDN help files, which is close to what I want and works just fine, but this tweak doesn't work. No input is accepted. The debugger will display that e.KeyCode is "NumPad5{101}", for example, but the debugger slides right over the first Case where I'd expect it to be accepted. Any other key gets the same result. What's missing here Private Sub txtExp_KeyDown( ByVal sender As Object , ByVal e As System.Windows.Forms.KeyEventArgs) _ Handles txtExp.KeyDown Select Case e.KeyCode Case e.KeyCode >= Keys.NumPad0 And e.KeyCode <= Keys.NumPad9 ...Show All

• gafferuk Error Message that I can't resolve...

  I am fairly new to writing in VB and in reality it is actually my first true language that I am trying to learn. I am currently writing a small application for where I work that will be used internally by only a couple of people. The purpose of this project is to record and maintain records for troubleshooting calls. This is in essence a CYA (cover your *ss) ploy that also helps us maintain with compliance rules. So essentially what I did was create a small program that would refernce back to a database out on one of our servers. This was supposed to be something that I assumed would be very easy, and at first it did seem to be working properly. Now I have run into a problem that I do not have a solution for. The following is the error I g ...Show All

• bchu How to install an assembly in GAC

  Hi, All dot net experts, The assembly is CrystalDecisions.CrystalReports.Engine version 10.2.3600.0. When I run my OneTouch deployment of my vs2005 win app converted from vs2003, I got this error saying "Unable to install or run the app. The app requires that assembly Crystalxxx be installed in the GAC first."

Check out this explanation: http://weblogs.asp.net/alex_papadimoulis/archive/2004/06/17/158295.aspx A module in VB terms is like a class with all members / methods defined as shared. So if you where to define a class with all methods/members defined as shared it would be the same. I would assume you are talking about this module rather than a netmodule which is something completely different. ...Show All

• polymorphicx Questions about Entry point in VS2005's winform

  In vs2003,every form has a constructor that invoke the methed InitializeComponent to initialize the form,but in vs2005 there is not a visible constructor that invoke that method.How does initialization of form work There is some confusion in here, and I'll try to clarify it. VB and C# are different with regards to how they call InitializeComponent. C# uses an explicit constructor with an explicit call inside the hidden FormX.Designer.cs file. For VB, there is no explicit constructor inside the hidden FormX.Desiger.vb file. Because of this difference, the VB compiler will automatically generate the call to InitializeComponent inside the synthetic constructor for the Form. If the user adds explici ...Show All
