I am having a weird issue with VS 2008 when I go to debug my program. When I click on the play button to run the program it flashes real quick and goes back to the VB IDE. No matter how many times I click on the play button it continually flashes and then goes back without displaying my form window or anything.
What type of setting would I need to change in order to correct this issue? I've been through most settings in the "my project" section and i do not see anything that could be causing it to do something like this.
My older vb apps I've made seem to work just fine when I click the play button on them. Only noticed this problem whenever I go and make a new vb app.

Did we install some third party Add-ins in your machine? If we disable Add-ins (“Tools” | “Add-in Manager”) and run “devenv.exe /safemode”, do we still have the problem? This can eliminate the possibility that third party Add-ins are causing problems.
We also can try to run devenv /resetsettings (Commonly, it makes sense than re-installation) or devenv /setup in Visual Studio Command Prompt.

Just check your output window.
Accessible from Menu-> Debug-> Windows -> Output. (Check image:1)
In output window select Show output from: Build combobox. (Check image:2)
This will give you perfect idea what is happening.
Following are the guesses.
The VBC installer is not installed or corrupted.
Some addon is registered to run before compiling and is creating problem.
....Long list until you tell whats shown in output window.
Also check Show output from: Debug in output window and Final check would be Immediate window.
I feel this three would give you hint whats going wrong.
Fixed.
Changing it to x86 instead of Any CPU worked!!!! :) But question is, why me having an Core i7 Quad doesn't support the program when i choose x64.....

Is the startup form correct? You can see that in project properties.

I'm writing a VB program where I want to be able to "push" an Exit button with a keyboard shortcut to close the program. I understand that if I put an & in the text of the button (E&xit), I can create a Alt-X shortcut to exit.
I've written programs where it's worked before; it's simple, but now it's not working. In fact, it's not even underlining the x in the text on the button. It's like a setting is telling it to be ignored. (I'm using the latest version of MS Visual Studio.)
I have found that if I turn on the form setting KeyPreview=True, it will work, but the x is still not underlined, so there is no visual indication of the shortcut being available. I feel like I'm missing some setting or switch that make this activate normally. Can someone explain or point me in the right direction? Thanks.
jmcilhinney, well, now it's working, both on new and existing apps, even with keypreview turned off. I think there was something strange going on with Visual Studio that day. Other parts of my program (with KeyPress handling) were not working correctly either at that time. Then suddenly everything started to behave as expected. Or maybe it was something I was doing with Keypress that messed up the Access Keys. I wish I could explain better, but now I can't reproduce the problem.
I am creating calculator VBO in blueprism object studio.
In application modeller I gave calc.exe path and able to launch calculator, but I am not getting identify option to spy on any element..
In Element, After clicking Launch buttion, identify is appearing for a split of sec and Launch button is coming back instead of Identify
PS- As mentioned in videos and links, I have launched calc via application modeller not directly via windows..
I am using windows 10, BluePrism V.5.0.11.0 versionenter image description here
Windows 10 calculator is complicated case, please consider using different application in your training. For example paint is much simpler to get started.
If you really need to get that going, then you may need to launch application first, using one object, and afterwards use second object to attach and interact with it.
can be two reasons
1. Either your application is not launched properly.
2. Sometimes we face problems with some versions of applications.
The best way to fix your problem is
Edit your settings remove the application path from the navigate stage.
Launch the application separately
Open Navigate stage > Action > Attach
Provide the window title within quotes (example: "Calculator")
Click OK then run the object
Now if you go to application modeller
You will be able to see the identify button under the element.
Hope this will help you.
I resolved this by unchecking "Disable invasive techniques (hooking)".
The Windows 10 calculator runs with process name win32calc which is also located under c:\windows\system32.
So when you launch the application please make you identify the applications process name and its location
I resolved this by circumventing to windows 7 calculator instead of a windows 10 calculator on windows 10.
Link to download win 7 calculator for win 10-
https://winaero.com/download.php?view.1795
This will be installed in the same place as your default calculator.
Inside-
C:\Windows\System32
The name of the app in my case was "calc1.exe" to avoid collisions with the default calculator.
I used this as my base reference app for spying and it worked.
Also note, the hover to highlight button seems to be a bit buggy, try a bit hit and trail to get you required button to be highlighted and mark using "Ctrl+LeftClick"
Okay, I have had the most aggravating problem with OpenFileDialog1. I have a program that I've been using for some 8 months, and in the past month, the program has begun to hang randomly when utilizing the OpenFileDialog1.ShowDialog() function. I have already read through all of the other posts about multi-threaded vs single threaded application. This did not fix it. Enabling the "Show Help" button did not fix it. I am mostly at a loss. here is a thorough walkthrough of the bug:
Run the application. I can always use the Open File button a few times with no problems. It freezes randomly after the program has been running for awhile.
The freeze happens after I push the ShowDialog button, and never displays the Open File Dialog window. The entire program locks up and hangs. If I pause it, Visual Studio doesn't show an error. It underlines the OpenFileDialog1.ShowDialog() in green, which is very odd.
I have found a way to break the freeze. Simply run a second instance of the program and use the OpenFileDialog function. As soon as it loads the file in the second instance, the first instance unfreezes. However, this is not a fix.
The only thing I can think of that may be causing this is the program also uses a WebBrowser1 control. It only seems to happen AFTER the WebBrowser control, which is on a seperate form, not the main form, has been initiated and utilized. Does this make any sense at all?
Thank you for anyone who can help me. I am about to tear my hair out.
Debug your program with dnspy, And when the software freezes, you will be able to see within the dnspy the actual code even if it is in a third party DLL.
I have solved this problem. It was quite unsolveable based on my description above, but hopefully I will help someone with this solution. The error is related to using the IE11 Emulation Control (11000) in the WebBrowser1 control. For some reason this interferes with OpenFileDialog and causes it to hang. I have no idea why. I changed my WebBrowser1 to use IE9 Emulation Control (9999) and the error has gone away. Thank you to those who looked into this. This is a registry entry in HKEY_CURRENT_USER.
I'm developing a Metro-style app (for Windows 8) using C# and XAML. I have set up my viewmodels to be used as design-time datacontexts, like so:
xmlns:vm="using:hub.ViewModels"
d:DataContext="{d:DesignInstance IsDesignTimeCreatable=True, Type=vm:ViewModels
My app appears to work perfectly when run, but in the design views of both VS 2012 and Blend, I occasionally get this (unhelpful) error message:
An Exception was thrown. TargetException: Error in the application.
Stacktrace
at System.ComponentModel.PropertyChangedEventHandler.Invoke(Object sender, PropertyChangedEventArgs e)
InnerException: None
This only happens in the design view - meaning I can't set breakpoints around all my INotifyPropertyChanged() events.
What is the best approach to debugging design-time errors?
If this happens consistently or semi-consistently, you can attach the debugger to the XAML designer:
Start Visual Studio; open your project and open a XAML file, causing the XAML designer to load
Start a second instance of Visual Studio. Open your project but make sure no XAML documents are open.
Ensure that Just My Code is disabled: From the Tools menu, select Options. Select the Debugging category. In the General page, ensure the check box next to Enable Just My Code is unchecked.
From the Debug menu, select Exceptions... and check the Thrown check box next to Common Language Runtime Exceptions. This will enable first chance handling of all CLR exceptions. If you know the specific type of the exception, you can enable first chance handling for just that type.
From the Debug menu, select Attach to Process. In the Attach to: field, click Select... and check the Managed (v4.5, v4.0) entry in the list and click OK.
This is necessary because the debugger may misdetect the process as a native process if it attaches while the process is executing native code. If your project contains native code, you'll want to check the Native check box in the list as well (you can debug both managed and native code at the same time).
In the Available Processes list box, find the xdesproc.exe that corresponds to your project and click Attach.
If there are multiple processes (usually because you have multiple projects open or because the designer is reloading or has recently reloaded), it can be difficult to determine which designer process belongs to which Visual Studio instance. It's often easiest just to attach to all of them. A tool like Process Explorer can help you figure out which designer process belongs to which instance of Visual Studio.
Note: Do not attach the debugger to a designer process (xdesproc) that belongs to the same instance of Visual Studio that you are using for debugging: doing so is likely to cause Visual Studio to hang. You must always use two different instances of Visual Studio.
Do whatever you need to do to repro the bug. When it occurs, the debugger will break at the point where the exception is thrown. The debugger should load the symbols for your assemblies.
I got here while looking for info on how to debug designer time instance problems, though I did not have the same problem as rikkit. But...I'm sharing the solution to a related issue just in case others having the same problem reach here as well:
Make sure you have the "Enable/Disable Project Code" toggle set to "enabled"...in VS/Blend 2015 it's a small icon below the XAML editor
as shown here.
If it's disabled, this could be the reason your design time instance doesn't seem to be working.
Further, if it's disabled and you attempt to debug using a second VS instance, then when you attach to the XDesProc any breakpoints you set in the code-behind will report that they "will not currently be hit. [because] No symbols have been loaded for this document".
You might think that you need to somehow load the symbols, but if you open up the Modules window attempting to do so, you won't even see your module in the listing.
I lost a couple hours on this issue because of this setting being disabled. Hope this helps others not do the same.
I'm not sure about it but I believe you can check for the IsInDesignModeProperty Field. I remeber having to do so on WinForms sometimes.

I'm developing a website with ASP MVC 3 and Razor in VS2010 SP1.
When I'm running the site from VS, if the view was open in the IDE, I can edit a view in runtime, and press F5 to show the changes, but if I open the view after run the site, then the view is locked (no message, simply I can write in the VS Editor)
When I stop debuggin the solution, the views that are locked remains locked, and I have to close the file and open id again in order to modify the code.
This behaviour is uncomfortable. Can anyone tell me why sometimes I can write in the VS2010 editor and other times I can't?
Other Notes:
The TFS is not the problem.
It happens in all the VS 2012 SP1 of my office.
It only happens in vb.net projects, not in C# proyects.
It didn't happens in VS2012.
I've disabled all the extensions.
Thanks.
I have experienced this as well.
I've found that just reopening the file, while in debug, works most of the time. The nearest thing I can figure is that you're not actually editing the file but actually viewing a debug version of the file.
This normally happens, for instance, a javascript method causes an exception within the source of that page. It then loads the active version of that page instead of the one you're editing. Though I've had it happen without any errors generated so I'm fairly certain that's not the whole issue. It might be worth posting an issue on http://aspnet.codeplex.com/workitem/list/basic It hasn't happened often enough for me to narrow it down but it sounds like it happens for you more often.
After more than a year suffering this problem, a solution was found.
This MS HotFix for VS2010SP1 solved the issue.
