I need to stop the execution of a program in VB.net. Within a repeating structure the program checks whether a variable is true or false. When the variable is false I need to stop the program execution. I do not want to close the program but simply stop it. One way I found was raising an exception, but I would not want to display the error message to the user. What is the best way to do it ?
Do
If myvariable=false then
throw new exception... 'Silent exception

I have an assignment to make a multiplication table using loops. The idea is to make this: If the user enters 3 this is the result he gets:
0 1 2 3
1 1 2 3
2 2 4 6
3 3 6 9
if the user enters 5, this is te result:
0 1 2 3 4 5
1 1 2 3 4 5
2 2 4 6 8 10
3 3 6 9 12 15
4 4 8 12 16 20
5 5 10 15 20 25

It works exactly as I need. But It looks really confusing, mostly because the array length is checked twice. There must be a clearer way to write it, but I can't think of one. the order that each statement is executed is crucial. i.e. Stuff 1 has priority over stuff 2, which has priority over stuff 3.
Say you press and hold down a letter on your keyboard. The first letter gets added, there is a delay and then it repeats quickly on screen. Is it possible to skip this delay and go straight to the repeating part? I realize this might not be a visual basic question as much as a windows question, but if there is some way of toggleing it through my program, or using a workaround, i would like to hear the alternatives ^^ Setting the windows setting to fastest still has a small delay and others users would still experience it on other computers.

The goal is simple... generate a set of random numbers with a certain range (e.g., 1-6, 5-10) with no repeats. I tried using a system with arrays where everytime a number has been generated, its marked as "used" and then the program is required to generate a new number. But it doesn't work!

I'm getting a bit more fluent in VB.Net, but am still a bit green around the edges in certain aspects. I'm creating custom controls, and am starting to rely heavily on AddHandlers to manage them.Until recently, I didn't realize that you can add multiple event handlers for the same control and same address
[code]...
The above code would create 10,000 copies of the same event, and if I would click on combobutton1, the event would fire 10,000 times. I only need to fire the event once, but sometimes my code is a bit circular, and there may be an instance where two or more addhandlers are designated for a given control and address. Is there a way to have a loop on my custom dispose event where it would look something like:

Or better yet, remove all events from a control(On a side note, is there any way in the debug mode to see all the active events attached to a control?)

this website seems great and this is my first post. Sorry if this has already been answered but I have been searching for a long time. I have a program with a list view in details mode. I have it load column settings (visibility, display index, width, etc.) when the form is opened and save them when closed. There are many columns...about ten so far...like folder, file, size, etc. Is there a way to access variable names from the values of other variables?
