I have a solution with two projects. The main project connects to the second project via a reference, and the reference path is local to my machine. It looks like it references the .exe file.So when I publish the main project (ClickOnce), i get the following error:
Application validation did not succeed. Unable to continue.In the log file, under Error Details, it says
System.Deployment.Application.InvalidDeploymentException (RefDefValidation)
- Reference in the manifest does not match the identity of the download assembly Project2.exe
- Source: System.Deployment
How can I include this second project? Should I publish it, then reference the published files? What do i reference? The .application file?Is there a way to just include this second project, so when I do publish the main project, the second one just goes along with it?
I publish my project normally to a folder in my computer. When I run the setup the following message appears:
"application validation did not succeed. unable to continue"
I am using a SQL Server database in my project, I don't know if it has anything to do with that..
I am installing an app I built in VB, and am getting the error "Application validation did not succeed. Unable to continue." I have successfully built and installed this app previously. What I think caused the issue is I attached the .mdf file I have referenced in my application to my SQL Server. I then detached the database in SQL Server, opened my VB app and re-built the app. When I tried to install the app, I received the error. Attached are the details of the error message.

When I do the try/catch method in my vb.net project I will try the code I want and when it can't do it, i make a message box right after the catch method. The thing is that it will show the message box, and then another message from the program itself. Like for example, I have here a MySQLException, and when i click ok on the message box, it will show another one right after showing the exception itself. How would I be able to get rid of this so the user doesn't have to see this, and the program can continue.
View 2 RepliesI was thinking I could make a console application that would have a FileSystemWatcher - watching for a .BAT file being created in a folder - and when it sees that file it does a PROCESS.START on it. But I'm seeing that a console app doesn't continue running.
Imports System.IO
Module awcWatcher

The service returns ValidationFault as it should, but instead of having the error message and tag which I've defined, it uses some generic values. Is this a bug or am I doing something wrong?

View 2 RepliesWhen using VB.Net (2008) and paused in debugging, Edit-And-Continue is a great time-saver. However if you change any module/class-level information (variable, sub/function signature, etc), you get the error message like this:
"unable to apply this change while debugging"
While I can understand the technical challenge to making this work (and why it would be hard), it leaves me in a tight spot with just a few options:
1) Restart and recompile and get the program back to the same state
2) Continue debugging without making the change, and risk forgetting
3) Type up a reminder note to make the change All of which are annoying.Now I know that option '4) Just actually make the change' may not be possible. but does anybody know how to enable the following 'technically easy' possibility?
4) Let me change the code, get it flagged with the purple squiggly underline, so I can save it, but just ignore the change until recompile
I have checked the Tools|options|debug|edit and continue, nothing appears to let me do this.

View 7 RepliesI have developed an application in VB.net 2008 having SQL Server 2000 as back end. I am running the application with MSDE 2000 on Windows XP. Now I have switched to Windows 7 from XP. I am unable to run the application on Windows 7 as it is not connecting to database.Can somebody help me to to run the application through MSDE 2000 without upgrading it to SQL EXPRESS 2008 on Windows 7. What I feel is that it could be caused by the Authentication Mode of MSDE 2000 in Windows 7.
View 3 RepliesI have a unique situation in that I've developed a VB.NET application for AutoCAD. The way this works, you build your project into a dll and utilize AutoCAD API references when designing the project. From AutoCAD, a "Netload" command will load your dll into it's namespace to run. AutoCAD then essentially takes ownership of your application from here on out. The application is ran using a command defined in a method's attribute:
<CommandMethod("CommandNameForApp")>Public Sub MyCommand()
'Code Here
End Sub
Due to the heavy load of processing loops as it evaluates AutoCAD drawing data, processes this data, and generates many, many Excel reports, I've added a boolean property called Cancelled to my Progress class. When the user cancel's the process, this is seen by the process and further evaluation is ended and everything is cleaned up nicely. In order for this to work though, I have to implement Application.DoEvents. Without it, the Cancel feature will not work at all. With it, now instead of allowing the application to stay loaded, the Command method is fully closed.I have added a go-to point and simply verify that the application isn't closing because of a user-cancellation event. Here's what it looks like now:
<CommandMethod("WireShop")> Public Sub WireShopApplication()
'Initialize Configuration File Data
'Initializes ValidBlocks, MarginDistance, WindowDistance, and HelpFileName Properties
If ConfigurationFileInitialization() = False Then Exit Sub
[code].....
In my opinion, this seems a little hokey. However, I'm not that familiar with exactly what Application.DoEvents is doing in the background to understand how to "head it off at the pass".

I have a datagridview on a form which is populated with data from our backend database. A few of my users are experiencing a problem when they select all the cells in the datagridview and try to copy and paste the contents into something such as Excel.
The error is: Requested Clipboard operation did not succeed.
Having searched for information on this error it appears that if a process has the clipboard already open (such as office) this will cause the exception being thrown (which is a system.runtime.interopservices.externalexception), usually when the code calls the clipboard.settext method (which I do not). However my form and its code does not even contain anything to do with clipboard manipulation, copy and paste or anything remotely to do with using the clipboard so I am unsure as how I can actually catch this exception and just report back to the user?

Now i could do this in a series of 10 if then statements im sure but using a structure theirs got to be an easier way.
