I brought this up with VS 2008, and nothing anyone told me worked. No matter what settings I tried, or how many times I slammed the computer against the table, VS would still break on all errors rather than just unhandled errors. Perfectly maddening. I'm having the same problem with VS 2010. But, this time I can't find a setting that at least lets me pretend that it's supposed to work.

View 13 RepliesI can't figure out how to get VS to break only on unhandled errors. I've tried this checking the "User-unhandled" box and unchecking the "Thrown" box for "Common Language Run-time Exceptions" and I've tried checking both boxes, and I've tried checking only the "Thrown" box, and I've tried unchecking both boxes.VS either completely ignores all run-time exceptions or breaks on both handled and unhandled run-time exceptions. Is my VS 2008 IDE broken or am I missing something?

View 2 RepliesSo when i build or click debug on my program. No errors come up and its smooth. So i decide to publish my programme. However. I come up with a bunch of errors during the publishing.
Here they are:Error 1 Cannot publish because a project failed to build. 1 1 Simple CALC

-new Dell laptop without a Break key.
-VB6 and VS2008 IDEs use Ctrl+Break to pause execution for debugging.
-I need a way to map another key combination to trigger a Ctrl+Break
My setup may make this easier or harder but to be clear I am running Kubuntu 9.10 (latest stable) and WinXP in a VirtualBox VM. Obviously all VB6/VS2008 dev is taking place in the virtual machine.So maybe it's possible to have the linux host send through Ctrl+Break based on a key mapping, or maybe it's possible to remap directly in WinXP. I'd settle for any solution as atm I need to use the XP On-Screen keyboard to send a Ctrl+Break.
everytime i try the space then underscore + enter it doesnt work and it lights up red edit - like for example this is a comment:'you must add such and such to this variable and then you must declare it' say i have that for a comment and i want to break the comment after variable. when i do this 'you must add such and such to this variable
View 2 RepliesI have a Datatable with one column of the table being 'PartNum(product part number)'. I used EntriesTable.DefaultView.Sort = "PartNum ASC" to sort the whole Table, with respect to the information in this column. Now I'm just trying to further sort the table by grouping rows that have same info under that column together and do something to each of such groups. but I'm kinda stuck here.
I'm thinking of creating some sub-DataTables out of the original one and have these sub-tables to hold those rows with same info under "PartNum". Does anyone have ideas how to do that? maybe with DataReader or DataView ,

I am getting these constant annoying errors in Visual Basic .NET 2010 Express. I'm pretty sure I'm not the only one, but these errors are always relating to images and resources The Type 'Global.ExampleProject.My.Resources.Resources' has no property named 'example.png'I am pretty sure these are bug, due to the fact that I get these errors after a while in most of my projects - it's absolutely annoying! Most solutions include removing the resources (commenting them out of the form designer code) and re-importing them... But then the problem comes back again after the project has been loaded a few times!
Microsoft suggest this is rather a user-related issue rather than a bug due to the fact that they can't reproduce the error.I'm still sticking to the belief of this being a bug - anyone get this error alot of the time?This is not the only bug I get - sometimes VB stops working when I try to build my projects!

In addition, you must run Visual Studio in the context of an administrator account. I have never worked on anything like this before and for right now I would just like to look at the code. I Googled and found this: You can enable these features in the Add/Remove Programs control panel. In there you wiull find a link off on the left labeled something like 'Turn Windows features on or off'. Click that and you'll get a UI for managing the IIS features that are installed.
I looked there and don't have a clue what I should check. I'm on Windows 7. What should my approach be? I don't want to just clicking things in the IIS configuration console. The attachment is what I see.

I have developed a windows forms application in vb.net 4 which connects to a MSSQL database. I have used the built-in tools to add the data source, data connection and data set. (Data->add new data source-> etc.) The application is installed on staff laptops which may or may not have network connectivity and may or may not be able to access the server on which the database is held. Obviously this is causing unhandled errors when the program starts and tries to make a connection to the database. (using windows credentials) Does anyone know where in the code the connection is made so I can go in and add some error handling? Or any settings I can change to get visual studio to handle the errors nicely?

View 7 RepliesI have a .net application that uses customerrors web.config module to display meaningful messages for errors. It works without any issues for 500 errors/exceptions caused by non-ajax and ajax components (updatepanel). However, in a scenario where updatepanel's asynchronous request times out, there is no error raised at all. I was able to see the timeout in firebug and come up with a solution that would at least display the error message as an alert and then redirect the user to the 500 error page using javascript but it's not quite doing what the rest of the application does in case of an unhandled errors like these. I basically just want everything to go through "LogEvent" mechanism so based on the severity of the error, it does the necessary work.This 500 error page doesn't have anything in the Server.GetLastError() for these timeout scenarios. Is this an expected behaviour? Can it be changed so I do have access to these timeouts in Server.GetLastError() OR maybe just run this error through "LogEvent" mechanism? Is there a better/more graceful way to handle this issue?
Below is my code to give you an idea, not exactly what I have in my application but pretty close.

I've written my own program to assist other engineers with their work at my company. Some people have been able to install the program with no problems, others can't seem to get it installed and I'm having trouble figuring out why. They install .Net Framework 4 as this is the Target framework that was setup in the file, although I don't think I fully utilize all the features yet and not sure when I will. I will post the portion of the log that contains the error. If anyone decode some of this so I can track down the problem. I'm not sure if downgrading the necessary version of .Net would work or not, but didn't want to be changing that unless there was a good reason too.
