I have a VB.Net WPF application with Option Explicit and Option Strict compile options set to OFF!
However, whenever I change build configuration from Release to Debug, or vice versa, my error list fills with hundreds of errors related to Option Explicit/Strict being 'ON'.
I have to go back into project properties/compile and change the options (which still display as 'OFF' mind you), back to OFF again... (i.e. I click the drop-down and re-click the OFF option).
Why? I have to do this so many times a day! It is not exclusive to just a single app, but with all the apps I write.
Do note:... this does not happen every single time, but it does happen at least 75% of the time.
FYI.. in-case this is of any relevance: My solution is on a Network Drive/Share, and I use Windows 7.

Im developing a system using vb2022 its almost done but today the changes I made doesn't reflect on run time.
For example I added a button but when I run the program the button will not show.
Same as the code, i can write code but it doesnt reflect on run time
Plus im trying to change the startup form into form 2 (initial is form 1) but it doesn't reflect.
What should I do? I didn't change anything I just opened the file and write code. But suddenly this happened.
Most likely your build is failing and VS is automatically running the old output. When that happens, VS will prompt you whether to run the old output or not by default, but many people tell VS not to prompt them again without actually reading the dialogue. Use the Build menu to build your project/solution and pay attention to the Output and Error List windows to see whether it failed or not.
It may be that the compilation is succeeding but VS simply can't overwrite the output files because they are locked, which does happen sometimes. In that case, just delete the entire obj and bin folders from your project folder. You may need to close VS to do so. The next time you build, new output will be created and run.
If this happens regularly then you should probably repair VS and, if it continues after that, reinstall.
I have a form with a button which opens a new form to add a new record to a table.
In Access on my PC (full version), everything works.
When I try to run it on a server with Access Runtime, I get an error saying something like:
this application has stopped working due to a runtime-error. The
application will now be closed
(I have the Dutch version, so I hope this comes close to the English dialog box message).
I debugged the VBA, but that doesn't seem to be the problem.
It has worked before:
Private Sub Knop62_Click()
DoCmd.OpenForm "Machines Toevoegen", , , , acFormAdd, _
acDialog, OpenArgs:=Me.Installaties_Id
End Sub
Well any un-handled error in the runtime will spit out the error message, and then as you experienced exit the application.
there are a good number of ways to approach this:
Improve error handling - make sure you don't encounter any un-handled error. I find this can be a LOT of work.
Another way? Compile your application down to a accDE. When you use a accDE, not only does the runtime ignore errors, not only does it NOT shut down?
It also means that all of your local and global variables are NEVER re-set. so global vars, and even global reocrdsets or anything else will retain their values, and do so even with errors. As a result:
Your application runs like a un-stoppable fright train.
Your local and even global variables retain their values. This allows use of application wide settings and variables that never re-set. And no re-sets ever occur even for un-handled errors. They remain intact for the given session (since the time the application was launched).
So, I would try running your application as a accDE on that server. It will not only become vastly more reliable, but it will also not shutdown on un-expected errors and even better it will retain the value of variables even when having encountered errors.
So it looks like you have some un-handed error. You can go on a treasure hunt to find this error, or just try a accDE in the meantime, and perhaps in the new years you might eventually track down the error or issue. But until then, just compile your application as a accDE.
To compile:
First, from VBA editor (just hit ctrl-g). And from the menu bar choose debug->compile. You MUST ensure that no compile errors exist before the next step.
If above compiles, then from UI (main ribbon), go file->Save and publish
From that panel, choose Make ACCDE.
Access will compile your application into a "access executable". Now try running this application with a accDE file extension on the other computer.
I have a desktop Windows Forms application I built.
As we try out improvements to the program, I make the changes on a test version of the application, which connects to a test copy of the Microsoft SQL database on the back end.
Basically, to start out, I just copied the program to a different directory, re-named the assembly, created a different PublicTokenKey and used that.
The problem is when I try to run a the test copy and the live copy at the same time. It pretty clearly thinks they are the same program (when I click on the second one, the "busy" circle simple turns for a second, then the already-opened icon in the taksbar gets highlighted), even though they show up in the Task Manager as differently named applications.
What do I need to tweak in Visual Studio so Windows 10 will recognize them as different, separate programs?
When i run one of my vb project i get below warning message.
DisconnectedContext was detected
Message: Context 0x21b448' is disconnected. Releasing the interfaces from the current context (context 0x21b2d8).This may cause corruption or data loss. To avoid this problem, please ensure that all contexts/apartments stay alive until the applicationis completely done with the RuntimeCallableWrappers that represent COM components that liveinside them.
A quick google search gave me result like it can be solved by disabling the exception "disconnectedContext ". So I did in menu->debug->exception, under manage debug assistants deselect disconnectedContext and it solved the problem too.
But this setting is not project wise or visual studio wise. I found like this setting is saved in .suo file.Now I want this setting I made to be available for all users using the project. So how it can be set project wise so that all users using the project will be able to get disconnectedContext setting disabled
Why isn't it standard behavior for Accurev to automatically run an "Update" upon opening the program? "Update" updates a user's local sandbox with the latest files from the building/promoted area.
It seems like expected functionality that the most recent files should be synchronized first.
I'm not claiming that it should always update, but curious as to why an auto-Update wouldn't be correct.
Auto-updating could produce some very unwanted results.
Take this scenario: you're in the middle of a development task, but you've made a mistake and need to revert a file that you just modified. So you open AccuRev, but before you have a chance to "revert to most recent version", you are bombarded with 100 files that have been changed upstream including the one you want to revert. You are now forced into the position of resolving all the merge conflicts before your solution will build, including the merge of your (possibly unstable) code in progress.
Requiring the user to manually update keeps a protective 'bubble' around the developer, allowing them to commit (keep) changes within their own workspace without bringing down code changes that could destabilise the work in their sandbox. When the developer gets to a point where his code is ready to share with others, that is the appropriate time to do an update and subsequently build/retest the merged codebase before promoting.
However there is one scenario that I do believe auto-updating could be useful: after a workspace is reparented. i.e. when a developer's workspace is moved from one part of the stream hierarchy to another. Every time we reparent we have to do a little dance:
Accept the confirmation dialog that reminds us (rather verbosely) that we need to update our workspace before we can promote any changes.
Double-click the workspace to view its files.
Wait for AccuRev to do a "Pending" search, to determine whether any file changes are waiting to be committed.
And finally, perform the Update.
Instead of just giving us a confirmation dialog, it would be nice if AccuRev could just ask us if we want to Update immediately.
I guess it depends on preference. I for one wouldn't like the auto-update feature.
Imagine you have a huge project and you don't want to build it every time you start Accurev. But you also can't debug because the source files and debugging info no longer correspond.
