I just started to publish my application into apple store.I've encountered few errors that make it unsuccessful to validate the app (Assertion Failure).
Image show the error that i got after run the code inside XCode
I already try few solution, but still can't solve the error. Any ideas?
Usually this type of errors are solved after run 'Product' / 'Clean Build Folder' in Xcode.
This error so far it doesn't affect the performance of the application. And I just untick the metal API validation in Xcode > Product > Scheme > Edit Scheme > Run > Diagnostics > Metal Api Validation and it works like a charm. Not to forget to Clean Build Folder of your project and run it again. Hope this solution help others in future.
I'm getting error message qemu-system-i386.exe has stopped working when debugging Xamarin.Forms app.
Searching the web, I found this solution: error message "qemu-system-i386.exe has stopped working". It basically says to "Wipe Data" and/or change Emulated Performance to Software GLES 2.0
The problem is that I don't see the options "Wipe Data" in this screenshot and I don't see AVD Edit -> change the Emulated Performance to Software GLES 2.0.
Am I missing something?
This is the screen I'm seeing when I go to Android Device Manager and click Edit. I don't see anything there that says "Wipe Data" or "Emulated Performance".
I have Visual Studio 2017 15.9.5.
Tools --> Android --> Android Device Manager --> Right click device --> Factory reset
I had same problem, unable to find wipe data action anywhere. Factory reset doesn't work for me. My problem is "To Start Android, enter your password" but i didnt found any ways to solve it without wipe data. This steps has solved this issure:
Run cmd.exe as administrator
My android-sdk folder location is E:\Android\android-sdk**, so change it to **E:\Android\android-sdk\tools
There is emulator.exe file, run it with emulator.exe -list-avds parameter for find your real avd names.
Now, if you have got your avd in list run emulator.exe -avd YOUR_AVD_NAME -wipe-data
Here is what i have:
I created a simple UWP app from the VS 2017 blank UWP template. No added XAML or C# code-behind:
Create new app with Blank Universal Windows template
Set Debugger type to Mixed (Managed and Native)
Build and Run (No XAML or code added)
Following error: WinRT originate error - 0x80070490 : 'Element not found.'
This happens every time. Does anyone have a handle on this error? If I don't have Mixed Mode debugging on, I don't see the error but I'm assuming it's still there. Is this an error that I should be concerned about?
Thank you.
A lot of problem may result this error, and it should not be a fatal error in your case. Most likely you changed the default Exception Settings in visual studio.
Just like all other apps, Windows use exceptions and catch them at different level.
For end user, you should not see this exception and app should not crash.
In your situation, I think you click continue and the program should not crash, and it should not be a big concern.
I suggest you:
1, start and debug your app, open Debug|Windows|Exception Setting, then click the 'restore the list to default settings' button
2, restart your app.
3, You should not catch the exception, but you still see error message in Output window.
If you still see a exception window popup, you need to post more information like your os version, and then someone can help you
I met this error when I call the winRT api CommunityToolkit.WinUI.Notifications.ToastNotificationHistoryCompat.Clear(). Then let the app toast someting once the error had gone.
I have an old WebForms app that I'm working on. I'm running in debug mode.
I get an error message when loading a page. It is a message from a dynamic script:
Javascript Runtime Error "False" is undefined
I'm stuck as to how to debug this. I was thinking that I might need to update a nuget package, but I don't know which one.
Update:
Get this error with IE 11. Do not get the error with Chrome.
Just in case someone else hits this. I was using LastPass password manager. For some reason the JavaScript did not behave when using Visual Studio debugging with IE. I turned the password manager (LastPass) off and we were home free.
I cannot start my website from Visual Studio 2010 anymore.
For a few days I cannot start my project in a web browser using F5. When I open my web application directly by typing the same url 'http://localhost/Default.aspx' everthing works fine.
When I run the project (F5) a new webbrowser starts, but after a few seconds it is stuck and Visual Studio gives an error dialog:
Microsoft Visual Studio
Unable to start program 'http://localhost/Default.aspx'.
OK
When I run the project in release mode it gives an extra error:
Microsoft Visual Studio
The following module was built either with optimizations enabled or without debug information:
C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\root\6552bec6\694bce32\assembly\dl3\8c9bd8d8\fb1d75cb_af26cc01\[name].Presentation.DLL
To debug this module, change its project build configuration to Debug mode. To suppress this message, disable the 'Warn if no user code on launch' debugger option.
OK
I have already repaired, removed and reinstalled Visual Studio 2010, I've tried using different browsers (including Chrome and Firefox), used different aspnet_regiis.exe options, etc. etc.
Nothing helps, and yeah now I'm stuck pulling hair out of my head ...
Anyone any idea how to solve this?
Does it work if you start it with [CTRL]+[F5] which runs without the debugger?
If so, then you have an issue with the debugger auto-attaching to the web server. I would check that debugging is enabled for your web project - a warning that usually crops up automatically from VS when it detects that a project is not built in Debug mode.
This is not as simple as switching the project configuration over to Release, because the DLL that the debugger is moaning about is one of the dynamically generated ones originated by Asp.Net itself.
Typically you should have, in your web.config:
<configuration>
<system.web>
<compilation debug="true" >
</compilation
<system.web>
<configuration>
(Along with any other stuff in <configuration> and <system.web> nodes).
There's also the possibility that Asp.Net debugging is not, for some reason, enabled.
Check out this msdn article on debugging asp.net applications in VS2010 for more information.
Note that if this is VS010 express, then you won't be able to debug - as confirmed by the aforementioned link; but since you way it used to work then I guess that's not your problem.
Update
Since that hasn't worked - you can try emptying the Temporary ASP.Net files folder. Easiest first is to do an iisreset. Then navigate to C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files and delete everything in it. I've had issues in the past where the Asp.Net binaries don't get refreshed and so when I'm debugging it moans that the files are out of date.
Change the View Browser to another browser. Run the view in browser or debug, then change back to original browser should work after that.
Had same problem, answer for me was to remove Avast Free AV. Everything worked for a year with avast free up until a week or so ago, uninstalling it fixed the problem.
I had this exact problem with Visual Studio 2008. The solution was to set the default web browser that VS uses to a real browser (e.g. IE) and not the "Internal Web Browser".
Right click on an ASPX file in your project and select "Browser With...". This lets you select the default browser to use when you select the "View in Browser" option and for when you debug/run the app (this is key).
Select your favourite browser (i.e "Internet Explorer") and click on "Set as Default". Do not pick "Internal Web Browser".
Debug away! Your app should come up in your browser now and debug as normal.
the solutions for me is to test with 127.0.0.1 in place of localhost. and all goes well for.
so the problem come from the host resolution name, to solve it please proceed like :
open cmd and then tape : %systemroot%\System32\drivers\etc\
open hosts file with notepad and the look for localhost ligne(you'll find 0.0.0.0 befor it )
change the 0.0.0.0 with 127.0.0.1 at all lignes with localhost .
I solved in this way:
Right click on a aspx page
Browse with set internal browser as default
Remove the previous default browser
Add %programfiles(x86)%\internet Explorer\iexplore.exe
Set this choice as default
For me I just did a Build /ReBuild on the project level and it started working!!!
I had the same problem. When I debug my code it says:
Unable to start program 'C:\homework.exe'. this system cannot find the file specified."
I'm using Microsoft Visual C++ 2010 Express but when I made a new project by the following steps:
Open C++:
Press new project
Press win32
Press win32 Console Application
Rename it
Click next
make sure: that the application type is console application
additional options: empty project*
Press Ctrl+Shift+A
In Visual C++/Code section press C++ File (.cpp)
rename it and press add
It works fine with for me now.
Please set your page name e.g Default.aspx revert to parent in IIS configuration
I'll share my experience with this same problem. This is not a solution, but someone may be able to figure out the problem from my particular experience.
I've been having this same problem for a few weeks now. (I don't know what changed on my system.) I do not run as local admin, because we are not allowed to have admin privileges on our PCs where I work.
Until today, I could expect F5 (Start Debugging) to start up a new local VS web server, open an IE window, and then issue an "unable to start program http://localhost:nnnn/Login.aspx" and "access is denied" error pop-up. If I closed the IE window, waited a few seconds, and then clicked F5 again, it usually started up my web app in debug mode just fine from that point on.
But today, that all changed. I did not change any configuration on my web app, which has been running fine, but I did add a couple of more classes to one of my subprojects. At this point, I could never get past the "unable to start program" message. I could run my app without debugging, but that was rather pointless. I even tried attaching to a running (non-debug) IE process, but that did not work.
Finally, I modified some of the properties in the WebAppName >Web >Servers screen. Specifically, I enabled "Specific port" for a specific HTTP port (which VS had been using all along), and I disabled "NTLM Authentication". I also enabled "ASP.NET" in the Debuggers section. Some of these I first clicked, then unclicked, then clicked again, saving in between each click.
This time, running with debug (F5) worked.
After running several times, I still usually get a "unable to start" error the first time after a recompile, but I can still usually get a debuggable running app to start after the second or third try. At least I'm back to where I was yesterday.
I suspect it has do with VS reloading its execution profile, and also probably something to do with permissions (since I cannot run as admin).
I'm using VS2012 with an ASP.net app that was written using VS2003... I've tried everything to get the IE page to open automatically when I select F5, or even Ctrl+F5... Haven't been able to get anything to work... However, I have stumbled upon a very poor work-around. When I select debug and I get the 'Unable to start program...' msgbox... I noticed that on the icon-tray I get a msg saying local-host has started
You'll notice a picture that the msgbox is pointing to:
Well, if you right click it, you get three options:
When you select the first: 'Open in Web Browser', it will open IE with the page your working with...
Like I said, it's a very poor work-around... but it works. This isn't an issue when I select debug using 'Chrome' or the page-inspector... But they have their own issues.
Try to turn on Bypass proxy for local addresses.
First you can go to your browser settings-> Change proxy Settings-> Connection-> Lan Setting and just check bypass proxy for local addresses.
If this solution don't work then also copy the following code check your web.config file for settings to bypass firewall:
<system.net>
<defaultProxy>
<proxy usesystemdefault="true" proxyaddress="http://proxy:port" bypassonlocal="false" />
</defaultProxy>
</system.net>
I easily resolved this problem by enabling script debugging in the browser.
When I ran into this problem (using IE 11) I noticed that iexplore was open about a hundred times in the task manager. After killing them all I was able to open my project just fine.
Since then, I have made a .bat file with this code:
taskkill /F /IM iexplore.exe /T
so now I just run the .bat when I get that error.
(alternatively you could run that code from the cmd)
I just ran into this problem in Visual Studio 2013. I had to enable Anonymous Authentication.
Click on the project node in solution explorer.
Hit F4 to show the properties window.
Change the Anonymous Authentication option to Enabled.
