I need to assign code to a button, that when clicked on, validates an ISBN code, and displays a message that it is either Valid or Invalid. I basically need help transforming code used in a console application that will now be used in a windows form application, so no more writeline stuff, now message boxes. [code]

I'm looking forward to reading and adding more to the community here. I've created a text based rpg. Next semester we are learning Visual Basic. I'm on winter break and I would like to get a head start on my learning. I've been working on creating some forms and message boxes. What is throwing me off, is that I have a good feel for doing coding so that I get functionality the will produce effects in a console. Coding the forms is a bit confusing for me. Is this something that others have run into? Is their some good primers for VB? I don't have my text books yet.
View 10 RepliesI'm running into some strange exceptions coming from a few workstations that are running one of our Windows Forms Applications. The application is written for .NET Framework 2.0 and coded in VB.NET. We've re-imaged the machines a couple of time but not matter what we do, the same problem occurs. We are not seeing this problem with any other machines besides these two. Below is the exception message and the Stack Trace. Can anyone provide any insight as to why this may be happening?

I have some friends who are 'old-school' VB6 database developers and I was telling them about .NET and its features, specifically ADO.NET. In our conversation, they brought up the following reasons why they would rather stick with ADO than move to ADO.NET: The Dataset is disconnected (What if power fails?)
The same amount of code still has to be written The new options of Dataset, BindingSource and TableAdapter seem confusing the same code is written programatically access the Database, all that changes is how that command is laid out. Why ADO.NET is 'better' than ADO with regards to data access when it comes to Windows Forms applications. What does ADO.NET provide that ADO does not? What does it do better than ADO? I'd like examples that do not involve LINQ.

View 4 RepliesI may be the only person still automating excel this way and I am looking at doing it in ways that better handle COM objects and such, but for now I just importMicrosoft.Office.Interop.Excel and go for it. Something that gave me a lot of grief at first was hanging excel.exe processes, but there are tons of resources online for fixing that. At this point I am pretty confident in my abilities to handle it.One thing I did notice and was wondering about is how does closing a windows forms application interact with excel.exe running in the background and likely more specifically the garbage collector. I have written quite a few excel automation projects and noticed that after I run my program .exe and it has completed there is an excel.exe process that hangs on until I close the pop up window from the windows forms application. Why is that happening?
View 1 RepliesI need to get a button to enter the applications subfolder and randomly select 1 file to be played in the windows media player COM which i have put in the form. I have tried creating a shuffling playlist but i cant get it to stop after one file is played (it just goes on shuffeling to another file, and i really do not want a playlist). I manage to create a batch file to be started to randomly pick a file in that folder, but when i do this the file is being played in the systems default player..

I have a program running in many machines in a network. The program reads a Sql database, and there's a table showing one table in a DataGridView in each computer from the same DB stored on the server. The same table in all the computers. What I want to do is, every time one computer changes something in the table, to update every table in all the computers.
Every program writes an entry in the database to know that they are connected to the DB. So any program can know who the other computers are.
How can all the computers know that there was a change in the table? (the idea is the get the changes quickly)

The problem:Sometimes message boxes in a console app close after clicking the ok button on one before all the messages are displayed. It is just supposed to display one message box after another. Same code as above, A message box in a console app will sometimes minimize to the taskbar before displaying all the messages after the OK button is clicked on The same code as the above 2 problem but in a Windows form app will display all of the message boxes, But.sometimes won't show the form at the end like it should.
The bugs I know happen when I run the programs from VB itself, don't know about the EXE outside of VB.I know it isn't my code because others have tried it and had no problems.What can I try to fix it?EDIT: Code for the one with the button and form:Public Class Form1

I am working on moving applications from Windows 2000 to new server Windows 2003 R2(64 Bit). I noticed that there are some VB programs and config files for those programs have been placed in Windows 2000 Registry. Some other applications are using them from different servers.Why do we use registry here? How can i move these to registry in windows 2003? Can I just move these or do I have to write VB programs to place them in 2003 registry?
View 1 RepliesI am doing an application where a person can enter a string in a text box. The application reverses it. That all works fine.
I am trying to set up an if statement where if nothing is entered in the box and Submit is clicked, a message box pops up and tells you that the box can't be empty. The message box pops up fine but when the user clicks on ok to close the box, another blank box pops up. How do I get rid of the blank message box?

okay so I have a simple code to generate card picks and store them in numbers except no two cards can be the same so my checkIf functions checks it against the current list. Also no four a values can be the same since there are only 4 cards of the same type in a standard deck.
