VS 2008 Skip Over Green Arrow Exceptions?
Jul 15, 2009
I'm using VS 2008 and .NET 3.5. I'm in one of my programs and when I run the program to test it, I keep getting these errors... 'Exception occurred' And the line is highlighted green and there's a green arrow on the side line (where you can enter breakpoints). When the code stops at these exceptions, I can hit continue and the code still runs just fine even though there were a ton of exceptions. Now, I'm wondering if there is a way that I can skip over these or have them not show up because I know the files that this is happening have not been changed in several weeks and I've tested this program beginning of this week and it was working fine... no exceptions or anything. I'm not sure what would've changed. The only thing I did was install the newest versions of Telerik Rad Controls. That should have nothing to do with the exceptions I'm getting.why i'm getting these now all of a sudden or how I can just skip over these without having to hit continue after each time?

I am trying to get the green label box to show the correct coordinate after the box is scaled. The red box always shows the true coordinate of the mouse in the picturebox. So for example - after you click on [Scale x4], the 32x32 picturebox will be 128x128. The red box will now show from 0-127 x and y. I would like the green box to show 0-3 x and 0-3 y. Does anyone know how to do this? The code is ready to run, just cut and paste. [code]

I've just skipped around a few inbuilt VB classes' methods which throws exception. of all that i've came across, methods may throw multiple exceptions but ALL of them are exclusive, meaning there is no way 2 exceptions will ever occur simultaneously, yea and i was trying to make my class throw 2 exceptions simultaneously, hence this question, must all exceptions be exclusive?

i have an app that pings all IP's on my network and then adds all alive hosts to a list, then my WMI query runs for all of them ips and gets some information. it all works fine except for when it gets to printers and switches/routers which obviously dont support WMI. Is there some way i can check if a device supports WMI and skip the query if it does not?

So I found this little morpg. The game is fun but really repetitive. I would like to simplify some of the tasks in the game. I do not know how to start this project. How can I recored arrow keys and then tell the computer to enter the arrow keys? One of the objectives in the game is to run around a farm 2x and scare away any wolfs. So the commands would be "arrow key up" for 30sec and then "arrow key right" for 4 sec and repeat. I have worked with robots in real life for some time. We would fill arrays with such instructions. One of the most fun things to program! But I have no idea how to do this in VB.

I have a problem detecting whether one of the arrow keys is pressed, all the other keys seem to be detected apart from the arrow keys??? I have set key preview to True........ It detects the arrrow keys BUT ONLY if I have NO other controls on the form??? example..
Me.Text = e.keycode
It works, but then if I add a button for example, it stops.

I need to be able to move it up with the up arrow key, down with the down arrow key, left with the left arrow key, and right with the right arrow key.I know my "Player" works by the way:
Private Sub PlayerPic_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PlayerPic.Click
MsgBox("test")

I'm encountering some rather strange behavior in the VB2008 IDE regarding exceptions. I tried to explain what I need as best I can in the title, but I'm not sure there's a succinct way to describe it.I'm not the best programmer in the world to say the least, so sometimes I do things that generate exceptions when I try to run them (This is why we test things continually, right?). Typically, in addition to the Exception Assistant popping up and giving a suggestion, the IDE highlights the code that caused the Exception in the Code Window.
Well, today I went back to a project I had been working on after putting it on hold for awhile, and while the Exception Assistant still pops up when there's an exception, the IDE doesn't auto-scroll and highlight the offending code anymore. I have no idea why it does this, nor do I know how to fix it. Resetting settings from the Import and Export Settings Wizard didn't fix the problem, and neither did trying to reinstall VB2008. Is there some setting, obvious or otherwise, that would cause this?

When I run my VB application (as far as I know any application) within Visual Studio I get a bunch of exceptions listed in the Immediate Window. They seem to refer to system files, not the files I generate. They also keep generating as the program processes data. Here is a sample.
Quote:
A first chance exception of type 'System.ArgumentOutOfRangeException' occurred in mscorlib.dll
A first chance exception of type 'System.ArgumentException' occurred in Microsoft.VisualBasic.dll
[Code].....
Any thoughts as to what this is and whether it is a problem. The applications seem to run fine.

I have made a really simple program launcher for my home theater pc that allows me to launch 6 programs, open/close the optical drive and shutdown.I don't have a mouse or a keyboard normally hooked up. I can navigate the buttons with the up and down arrows fine, but only in the tab index order. Is there a way to allow the left/right arrows to focus on the buttons to the side? Here is a screen shot of my application to hopefully give a better idea of what I'm asking. (eg. Can I hit the right arrow from my first button and focus on the Open button?)

I have a group of radio buttons inside a groupbox and I don't want the user to be able to move the focus away from a button by using the arrow keys. I've tried the following keydown event, but it never gets fired:
Private Sub rbCode_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles rbCode.KeyDown
' If an arrow key is pressed, maintain focus on this radio button
If e.KeyCode = Keys.Left Or e.KeyCode = Keys.Right Or e.KeyCode = Keys.Up Or e.KeyCode = Keys.Down Then

Is there a way I can catch and handle two different exceptions within the same exception type? For example:
Try
' My code
Catch ex As System.Net.WebException
End Try
I have 2 different exceptions that are System.Net.WebException. I want to handle them different ways. Problem is the catch block above catches them both. Is there a way I can determine if which of the two it is and handle them differently?

I have already incorporated DirectX into a program and set the owner to a picturebox which so far works great, but all it does is set the place/dimensions of the directx window to the picturebox... it doesn't actually USE the picturebox for the video so if i pause the video or set a timeframe I can't use the picturebox frame/image to pull information from. So what I want to do is when i pause the video at a certain frame I want to be able to actually take a snapshot and populate the picturebox with that image and then be able to save/manipulate it like a normal picture. I have read some examples and coding on screen snapshots using DirectX.3D, but not audiovideo. Not sure if its the same or what. I know normally you would start out with CODE, but in this case I have NO IDEA exactly where or how to start it.. I tried Bitmap options with the screen area/location, etc... but was getting errors and exceptions..

So I've made this control that inherits from the treeview control and basically loads objects from active directory into a treeview (url...).All working fine, but as this is the first custom control I have made that I have intended for other people to use, I'm not quite sure how I should approach error handling.I mean, obviously I shouldnt do something like show any exceptions in a messagebox because that might not be what the person that is using the control wants to happen. So do I just write out exception messages to the debug window? Do I swallow exceptions (guessing not)? Do I just totally ignore them so that they are thrown in the user's project?

i created a Class library (.dll) and loaded it as reference into a main project. In the code for the class i've handled exceptions using try..catch subs, however when debugging the main project exceptions that are handled in the DLL still get thrown! (the class ".vb" file gets loaded into the debugger and the line of the exception shows up)
Up till now i've found it useful that when an unhandled error occurs in the imported reference, it shows up in the main project with tracing back to the referenced class. But i dont want the exceptions that are handled in the reference class to be thrown when debugging the main project!
As you can see the exception thrown was handled with try...catch this class exception.vb belongs to the project that created the class library (.DLL that i referenced). i didnt even load the project that built the reference so it amazes me that it could find the coding class to begin with.

In the following function I get the green squiqly line warning at the end of the function that when you hover the mouse over it, it reads: "Function 'AllQuotesDal' doesn't return a value on all code paths. A null reference exception could occur at run time when the result is used.". I've tried and tried to make it correct and safe but it won't compile the way I've tried playing around with the variable 'reader'. It seems to need to be the way I have it but I want that warning to go away.
Code:
Public Function AllQuotesDal() As OleDb.OleDbDataReader
Try
Dim connection As OleDb.OleDbConnection = NewConnection()
