in VS 2015, there is a warning dialog 'null' is null or is not object when i try to create a VC++ project:
then i get another warning:
error from HRESULT:800A138F
in VS 2019 i got the warning:
Object reference not set to an instance of an object,
You could try steps below to resolve this issue:
1.Windows+R and enter regedit to open Registry Editor, make sure the value data of Enabled key is set to zero.
We can find the key here:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\FipsAlgorithmPolicy
2.Restart VS to check if the issue goes away, if it persists, close all vs instances and delete all folders under path: C:\Users\xxx\AppData\Local\Microsoft\VisualStudio . It will clean all VS cache to reset the VS settings.
Note: AppData is a hidden folder.

So I tried making a basic game on the console using screen buffers, I was able to create it and make a square move in the canvas, but for my next project I looked up a website with the ASCII characters and pasted a couple into a comment at the end of the c++ file, when I ran the file visual studio prompted:
I clicked yes and it didn't run anymore.
Also I recently have installed an extension for visual studio (before it didn't run, the extension works fine but I don't know if the extension may have caused this as I didn't tried running it with the extension downloaded and applied), when I open visual studio and open a file it says:
The last record in the ActivityLog xml file, has a type of error and it's description is:

I have Visual Studio 2017
So why does running the file (with the local windows debugger button) say that there were build errors? And how can I fix it?
When it prompts the build error, and I click no it usually shows the errors but in this case it doesn't, yes will just run the last "successful" build (although I haven't changed the file since I have finished it before this error message started popping up)
Also there is no error in my code as I was able to run it before the build error kept appearing and I haven't touched the file since(only now to show the problems are)
Thanks for your time! if anything was unclear because of my English, comment and I'll try to clarify it
I fixed the error by deleting ComponentModelChache folder located at:
C:\Users\%userName%\AppData\Local\Microsoft\VisualStudio\15.0
15.0 is the version of your visual studio so it varies depending on the version you're using, %userName% is a replacement for the user you're logged in as
I am creating a visual studio 2017 extension in C# for pending changes. I got reference from here.
I am trying to get the instance via GetService method.
But everytime I am getting teamExplorer as null.
Microsoft.TeamFoundation.Controls.ITeamExplorer teamExplorer;
teamExplorer = base.GetService(typeof(Microsoft.TeamFoundation.Controls.ITeamExplorer))
as Microsoft.TeamFoundation.Controls.ITeamExplorer;
Can someone please help me in this ? How can I get the instance?
I am trying to get the instance via GetService method. But everytime
I am getting teamExplorer as null.
The method is too old you cannot get what you want by using GetService() method. You can try my steps to realize it which l have tested successfully.
1) Reference the Microsoft.TeamFoundation.Controls.dll under the path C:\Program Files (x86)\Microsoft Visual Studio\2017\xxxxx\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer.
Note: you should reference the related DLL in this folder and these APIs are for Visual Studio 2017.
2) change to use these codes:
Microsoft.TeamFoundation.Controls.ITeamExplorer teamExplorer;
teamExplorer= Package.GetGlobalService(typeof(Microsoft.TeamFoundation.Controls.ITeamExplorer))
as Microsoft.TeamFoundation.Controls.ITeamExplorer;
Hope it could help you.
Visual Studio 2015 Community update 3, trying the C++ code analysis feature. The settings are as follows:
solution properties > code analysis settings > [all configurations] [all platforms] : microsoft native recommended settings
project properties > code analysis > [all configurations] [all platforms] : microsoft native recommended settings
Whenever I run analyze > run code analysis on solution I would always get a c1xx : fatal error C1253: Unable to load model file 'res://mspft140.dll/300'. This happens to every project, new or existing. MSDN is not particularly helpful about this one.
The string is a res protocol, so I checked if the dll mentioned is at its correct location (there are two actually, at c:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin\ and c:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin\amd64), and opened them with resedit. Both contain an XML resource named 300, so I don't see any reason for VS being unable to load it. Resetting the settings didn't help, full uninstall and reinstall (half a day wasted) did neither.
I also ran procmon with [Path] [contains] [mspft] filter while running the code analysis in VS, but the file system results are only SUCCESS and FILE LOCKED WITH ONLY READERS, which seems to be ok.
Did anyone experience this error? Does anyone have any surmises about its cause?
Update: After looking thoroughly through many more procmon captures with different filters I found out that cl.exe tries to open this registry key value: HKCR\PROTOCOLS\Handler\res\CLSID. Clearly it looks for the handler of the res protocol mentioned in the error output - and it's not there to be found, while many siblings of res key refer to some valid handlers, for example, http key has CLSID value of {79eac9e2-baf9-11ce-8c82-00aa004ba90b}. I guess that my quest for now is figuring out what that res CLSID is meant to be.
I was right in my assumption about the res protocol handler. The correct HKCR\PROTOCOLS\Handler\res\CLSID value is {3050f3bc-98b5-11cf-bb82-00aa00bdce0b} (which refers to C:\Windows\System32\mshtml.dll). For some reason my registry was missing it; as soon as I added the value, the code analysis started working without errors.
I hope this helps someone, although I believe the bug is extremely rare.
I am currently trying to upgrade our c++ mfc solution from visual studio 2010 to a visual studio 2013 solution. When i try to build it i get the error MSB4018 The "ResolveComReference" task failed unexpectedly. I enabled fusion logging and this is what it tells me:

I understand that msbuild has been moved, but i dont understand why it is trying to find System.dll in the msbuild path, how can i make it look for it in its proper location?
Edit:
I have now also tried upgrading to visual studio 2012 which worked without bigger problems and I did not run into the same problem. However i noticed that when running devenv /upgrade (with vs2013) it seems to completely change everything under vc++ directories (it stayed unchanged when upgrading to vs2012). Could this have something to do with this issue?
Edit2:
Tried to build the project in vs2013 after upgrading it to 2012 (without running devenv /upgrade), this also didnt work so I guess the problem is not related to that...
After enabling diagonostic build output i found that it was 3 broken COM references in the project that where failing to load. Removing these references solved the building issue. These where only showing up as warnings in vs2010 but resulted in MSB4018 in vs 2013 for some reason.
This is your problem:
LOG: Appbase = file:///C:/Program Files (x86)/MSBuild/12.0/bin/
Fix the base folder in your build system if you really need it to point to another filder. However it would probably be better to redo you build system targeting 2013 instead of patching the 2010 version.
I want to ask about cascadeclassfier load doesn't work in release.
I using Microsoft Visual Studio 2010 and OpenCV 2.4.7.
my code:
CascadeClassifier cascade;
if(!cascade.load("D:/data/training.xml"))
{
printf("Error load XML!\n");
return -1;
}
Things i've tried so far:
Tried to specify the path manually using ""
Tried to use / or \ in the path
Tried to give user permission
Tried to call the xml without using absolute path
Tried to use many kind of codes i've found when searching this error
Tried to seperate the xml by creating a new folder for them
Additional Information:
Running in debug mode work 100% perfectly
Running in release while using visual studio trigger a break
Running using the exe created while building only show "Error load XML!"
i really confused right now, so i decided to ask..
Thanks before.
I've had similar problems when switch from Debug to Release Mode. I had copy config from Debug to Release and mistake at Linker > Input > Additional Dependencies. And I had fix this problem by using opencv_world320d.lib for Debug mode and opencv_world320.lib for Release mode.
