• Bloom326984 Newbie help with collections VB.NET

  Hi all, I Hope this is the right forum. I'm new to the .Net world... taking my first class and just getting my feet wet. Overwhelmed might be an understatement... Having said that, I'm trying to set up a simple collection (as a vb.net console application) that simply receives a few names from the user, puts them into a collection and then displays that collection. I'm having trouble adding the user input to the collection. Can you show me what I'm doing wrong Thanks, John I get this error: Error 1 Argument not specified for parameter 'value' of 'Public Overridable Sub Add(key As Object, value As Object)'.

• hlj16 2005 Windows Service calling VB 6.0 Program with UI?

  Well, back to what I was working on yesterday. I finally have my Windows Service (tiny little program) that, onStart, will check to see if another program is running and, if not, will launch that program. Right now I have it launching Internet Explorer. I **HOPE** that this is an easy problem (something a newbie like me could understand). When I start my service, it will launch the application (if it's not already running). However, I can't see the application. I've used Notepad and I've used Internet Explorer. When the service starts it writes to my little log file saying it was started at such and such a time. However, you will not see the Notepad or IE window open up. If you go into Task Manager, then you'll see iexplore.exe or notepad. ...Show All

• Theoblob Creating Dynamic Link Library

  Hi all, I'm used creating Windows Applications in VB2005, but now I need to create a DLL for use in a little project of mine but I don't have any experience creating them in vb2005. I did watch a code of a vb6 dll but that didn't really help me. Maybe someone can give me a quick start. Like what type of project I should use, maybe some initial code etc. Thank you in advance. In VB2005, you can create a "class library." This will package your VB classes, modules, and methods into an assembly which is stored in a DLL file. Creating a "class library project" will give you a good starting point. Ok. So far it seemed to work. Only, when I set the dll as r ...Show All

• vannielou how2 show "access key" underlined on button

  I've added access keys to buttons on forms written in VB2003. Now, when migrating to VB2005 I see that the access keys still work but the key is not underlined in the form's button.

• Koray Samsun what is wrong with this?

  dim y_m as double dim y as integer y_m = 6.09 For i = 1 To 12 y_m = y_m + 0.01 y = y_m If y_m = CDbl(y + 0.12) Then y_m = y + 1 End If Next When y_m is 6.12 the if statement doesn't catch that fact!!! The CDbl() function doesn't seem to help. It doesn't work whether or not I have the conversion function. Single precision is even worse because adding 0.01 several times gets you not 6.10 and 6.11 but something crazy like 6.110002.

• Raoshan Tabbed Browser - How to add new tabs?

  Hey, I'm trying to create a simple web browser that supports tabbed browsing. (That is, using to tabs to open multiple windows without launching the program multiple times.) I have everything except the actual tab part complete. I need to know how to add a tab and assign a web browser to it. I can get it to add the tab but assignning the browser as a child is beyond my knowledge. If at all possible a full example of a tabbed browser would be most effective for not only completing the task but also for me to learn how to do it. It that is not available any help would be just as highly appreciated. I am using a TabControl and a WebBrowser for controls and both seem to work correctly. Other than that there a ...Show All

• DanMeyers C# typeof -> VB equivalent?

  I got a library written in C# that has a class that exposes a method similar to this: class Test { ... public void DoSomething(object value, Type type) { ... } ... } If I would call it in C#, I would e.g. call: new Test().DoSomething(myValue, typeof(string)); What is the equivalent of the "typeof(string)" expression in VB I googled and found a lot about some VB syntax to compare types with "Typeof something is SomeType", but what is the VB keyword for getting the Type (class instance) from a type keyword like 'String' No, that is not what I was looking for, what you are writing there would be the equivalent of if (this.TextBox1 is TextBox) { ... } what I was looking ...Show All
