Everything was working just fine...then one time running the debugger and I'm given a 401.2 error from IIS Express 7.5. I created a new project and tested - worked fine. I ensured the web.config and other project settings where identical - still getting the error in the original project!

I am working in vb express 2008. I got some sample code from the site www.vbhelper.com and tried to implement it as it is. Debugging of the code gave following errors:Error 1 'Protected Overrides Sub Dispose(disposing As Boolean)' has multiple definitions with identical signatures.

Why does my VB.Net Project disappear instead of giving an error message?This only started happening recently, but when debugging with Visual Studios instead of getting errors, the program just closes as though the stop button was pressed. This doesn't happen for all error types but it consistently happens if there is some sort of casting error. This is an overly simplified example, but the lines below would cause a program to vanish as soon as they run. Dim i As Integer i = "A" One other interesting part of this is that if that was in a try catch block the error would be caught instead of closing the program.I'm in an office setting so I've been able to test a number of configurations and have found that this problem only affects Windows XP PCs, but not Windows 7. And it consistently happens with Visual Studios 2010 Professional and Ultimate, Visual Studios 2008. Besides that we apparently we all need Windows 7.
View 1 RepliesI have a windows 7 computer with vb 2008 express on it. it works really well, except only one thing. when I try to debug an application ( usually windows forms), it produces a run-time error saying: Error while trying to run project; unable to start debugging.
View 2 RepliesI am working with visual studio 2008, developing a simple windows form app. in VB. but a very weird situation has presented itself (at least I think its weird).When I try F5 or any other way to start the debugger I get this message:"Error while trying to run project: Unable to start debugging.The debugger cannot connect to the remote computer. This may bebecause the remote computer does not exist or a firewall may be preventing communication to the remote computer. Please see Helpfor assistance."Needless to say, Help is Helpless.The weird thing about it is that this only appears if my computer is not connected to the home network and only in VB. When I try to debug on any other language it works fine, or if I connect to the network then VB debugs fine. I do not think I am using a remote debugger.

I'm using visual studio express 2008, I wrote my code for a project and then when I tried to debug it I got a few errors but one main one that says this. Visual Studio cannot start debugging because the debug target "".exe is missing Please build the project and retry, or set the output path and assembly names appropriately to point at the correct location of the target assembly. Since this is my first time debugging a program with this particular instance of the program, I am in shock. Does anyone know how to fix this issue?

When I try to debug my program, it sometimes catches the first breakpoint, but as I step into each step, it just skips and runs the program. Is there some kind of setting that I can make in vb 2008 express that will allow me to see my code step-by-step?

However, when I try to access a crystal report it gives the exception below. This user is able to access the report from its network location in windows explorer so I assume the act of asking Crystal to copy it locally is causing a problem?
Therefore, can anyone advise where the local copy will be created and/or how I can control this.

I'm testing my Visual Basic .net application by running it in Visual Studio express.Sometimes it runs OK, but other times I get an exception (details below, if useful). I'm not sure why I get the exception as the particular part of the application that I am testing re-uses code that works OK for other features.
What should I check, what would give me a hint as to the root cause. Things I tried so far are: Rewriting some of the code to be more robust. The outcome of this was that this approach was getting out of control - I was correcting everything. I made changes such asing alternative libraries (e.g. replacing CInt with convertTo etc). Some lazy declarations, but it occurred to me that there was no problem with these with the code before my changes. And every change I seemed to solve uncovered yet another problem, another different exception So I thought something must be fundamentally wrong with my installation, and a search found discussion group posts from people experiencing something similar. The suggested remedy would be to re-install the .net framework. So I did that and the problems still occured.
Any thoughts on approach to get to the root of the problem? I'm not asking for a solution but some fresh ideas would be very welcome.

First of all, please feel free to skip this entirely if you can understand the questions below.I'm still very fresh new to .NET, but an elder monkey on bad old ASP in regular VB.I just got into a company with some legacy .NET VB files and now I have a couple of huge projects, with over 50mb of files and about 1gb the whole project and debugging them haven't been easy. I've read through w3schools tutorial and did many google researchs to get to this point in which I just can't make this work. And unlike in another very similar question I don't think this is a simple issue.
I don't know if those projects are MVC or regular Web Application, but I was told to use "Other Project Types > Visual Studio Solution > Blank Solution" and then "Add Existing Web Site" to that. With no further instructions or orientation, I see they all have DLLs and makes me believe they are not MVC.
Anyway, whichever this or many other ways I've tried to add the files into Visual Studio, I could never use the Debug properly with one of them. One works fine enough, I can at least see it running locally very alike from the webserver. But the other gives me many random errors and warnings to "compile" the debug and run on Visual Studio's own server (I think it's called "ASP.NET Development Server"). Some errors shouldn't even exist like "The file XXX doesn't exist" while I can easily verify it does exist!
I don't really expect to have much help here, but I still hope to find some. Sorry if this is too much.What options do I have to debug a big Visual Studio project that already works online in a server that have debugging and even error options turned off?How can I know how to properly "import" an existing project into Visual Studio to begin with?Is this a homework question?(new) Given I have 3 places to sync many files (local, shared production network and live) what's the best approach to work on and debug existing errors? Out of the box thinking is always welcome (converting project, not using Visual Studio, older version, whatever)

View 5 RepliesIf I put this piece of code in a new fresh vb.net form, add a button and two labels and start debug I get execution time of about 11.5s.If I put the same piece of code in a new form in an old project upgraded from an earlier version of vb.net, start debug I get an execution time of 7.5s.So I do exactly the same in the two projects but get different execution times.
What do I have to do with the fresh new project to get the same execution time ?I am not interested in improving the code to be able to calculate primes faster. I just want to know what is the significant difference between an old upgraded project and a new fresh one. I am using windows 7 64bit on a 2,4 Ghz Intel quadcore.
