I have installed EmguCV 2.4.2.1777. I have a 32-bit windows 7 so I installed it using the installer. Now I am trying to write a simple code to capture a webcam's video in a window in C#.
The problem is after during execution I am getting the following famous error:
A first chance exception of type 'System.DllNotFoundException' occurred in Emgu.CV.dll
A first chance exception of type 'System.TypeInitializationException' occurred in Emgu.CV.dll
An unhandled exception of type 'System.TypeInitializationException' occurred in Emgu.CV.dll
The file Emgu.CV.dll is present in the folder. I don't understand why its giving that error.
I tried all the checks which are suggested by fellow stackoverflow users and also many other references:
1) Installed MSVCR: MSVCRT 10.0 SP1 x86
2) copied the OpenCV dlls to the execution directory
3) I also have a 32-bit OS. So that also should'nt be an issue.
But when I checked for dependencies, I faced a problem:
I used DependecyWalker to open cvextern.dll and found the following dependencies missing:
NVCUDA.DLL
API-MS-WIN-CORE-COM-L1-1-0.DLL
API-MS-WIN-CORE-WINRT-ERROR-L1-1-0.DLL
API-MS-WIN-CORE-WINRT-L1-1-0.DLL
API-MS-WIN-CORE-WINRT-ROBUFFER-L1-1-0.DLL
API-MS-WIN-CORE-WINRT-STRING-L1-1-0.DLL
API-MS-WIN-SHCORE-SCALING-L1-1-0.DLL
DCOMP.DLL
IESHIMS.DLL
It also gave the following:
Error: At least one required implicit or forwarded dependency was not found.
Warning: At least one delay-load dependency module was not found.
Warning: At least one module has an unresolved import due to a missing export function in a delay-load dependent module.
Please help me out with the exception. Thanks in advance.
I copied all the dll files from C:\Emgu\emgucv-windows-universal-gpu 2.4.9.1847\bin\x86 to a folder called includes in my project and updated the "Copy To Output Directory" Option for these DLLs to "Copy Always" and it got rid of this issue.

I have a UWP app that compiles successfully if I have UseDotNetNativeToolchain off. But when I turn it on, it gives me the cryptic error:
Internal compiler error: Object reference not set to
an instance of an object. UWPApp C:\Program Files
(x86)\MSBuild\Microsoft.NetNative\x86\ilc\IlcInternals.targets 887 Build
This is all it gives me. What could be causing this? How can I drill down on this.
Using VS2015
Here is the full build output in case that helps:

The solution to this problem was to disable optimization in a few assemblies I was using in the Default.rd.xml file. E.g.
<Assembly Name="IKVM.OpenJDK.Core" Dynamic="All" DoNotInline="true" DoNotOptimize="true"/>
This is a super weird question for Visual Studio 2013: Windows Forms Application 3.5!
I designed and made the program, then I ran the program for the first time and an error pops up.
And then I click cancel, retry and this time I click yes and this pops up:
Error while trying to run project: Could not load file or assembly
'SourceProject' or one of its dependencies. The located assembly's
manifest definition does not match the assembly reference.(Exception
from HRESULT: 0x80131040)
Any ideas on fixing it?

Just open your Debug Configuration near by Application Run Button in VS. Then , Choose debug with Any CPU to x64 or x86 .. May be it will help someone.
Thanks,
I have a funny problem on my machine
Windows 7 x64, using QT 5.2 for the GUI
I'm not able to start the app I always receive the error
First I thought I had a broken dll, so through some trial and error I found a solution:
I add the QT5Core.dll via enviroment path, and NOT directly to the app folder. Then the programm works. If I copy the dll back to the app Folder, Same problem as before!?!?!?1
I'm really confused, because the error only occurs on my machine?
Debugging doesn't really help,
In code, the error occures here:
MyApplication::MYApplication(int argc, char** argv, int version)
: QApplication(argc, argv, version) // <<< this call fails!
{ }
somebody can help me?
Why is the location of the qt5core.dll a problem?!?!?
UPDATE
I used the profiling function of depends and found the following behaviour:
Failing
GetProcAddress(0x76800000 [c:\windows\syswow64\KERNEL32.DLL], "CreateSymbolicLinkW") called from > "dirone\xxxx.EXE" at address 0x00FF2877 and returned 0x7688CCE9.
First chance exception 0xE06D7363 (Microsoft C++ Exception) occurred in "c:\windows\syswow64\KERNELBASE.DLL" at address 0x765CC41F.
Exception: "bad allocation"
Working
LoadLibraryW("C:\BuildPackages\QT\plugins\platforms\qwindows.dll") called from "dirtwo\QT5CORE.DLL" at address 0x66AA5154.
Loaded "c:\buildpackages\qt\plugins\platforms\QWINDOWS.DLL" at address
0x0F380000. Successfully hooked module.
somehow the path to the qwindows.dll is hardcoded into the dll (there is no environment path to this directory)
If I rename the qwindows.dll or delete it, startup failes again.
BUT the qwindows.dll is bundeld with our product. It is in a subdirectory ./platforms/
AND the files are the same (diff returns equal)
Somebody have some clue what I should try next?
Check if you already have some qt related environmental variables.
Crashes are usually due to this, remove those envronmental variables first. Check whether you have any other qt installed libraries.
it would be better if you can post the cal stacks.
Some other dlls are needed that reside in the directory of the qt5core.dll. When you add this path to the search path the dlls are found. When you simply copy the dll these dlls can not be found. You can check dependencies with the depends tool.
Candidates for the additional dlls are:
icuin51.dll and icuuc51.dll
Found the Problem:
The enviromentvariable:
QT_QPA_PLATFORM_PLUGIN_PATH=C:\BuildPackages\QT\plugins\platforms
was set to the path. If removing this variable, everything works as it should!
So I downloaded and installed Microsoft Accelerator v2 to use ParallelArrays. I have referenced it in my project but when I try and execute the code from the module in a script file I get:
"The namespace 'ParallelArrays' is not defined
I have followed the instructions on this post:
Microsoft Accelerator library with Visual Studio F#
I've added a reference to the managed version "Microsoft.Accelerator.dll" to my F# project and then added the native "Accelerator.dll" as an item in my solution and set it's 'Copy To Output Directory' to Copy Always.
Still getting the FSI error and inline error in my script file on the '#load ...' line, however the solution builds fine, and no error in the module file.
Any ideas on what I'm missing? I'm sure it's something stupid.
Thanks,
Justin
UPDATE
I tried mydogisbox's advice, which got rid of the error above, but now when I run the code in the .fsx file I get this error instead:
--> Referenced 'F:\Work\GitHub\qf-sharp\qf-sharp\bin\Debug\Microsoft.Accelerator.dll' (file may be locked by F# Interactive process)
[Loading F:\Work\GitHub\qf-sharp\qf-sharp\MonteCarloGPU.fs]
error FS0192: internal error: F:\Work\GitHub\qf-sharp\qf-sharp\Accelerator.dll: bad cli header, rva 0
UPDATE 2
So the bad header error has dissapeared, but now I get this instead:

I found this thread on MSDN however the answers proposed as fixes on that thread barely even relate to the question.
http://social.msdn.microsoft.com/Forums/vstudio/en-US/98600646-0345-4f62-a6c5-f03ac9c77179/ms-accelerator?forum=csharpgeneral
My Direct X version is 11, and I imagine that will suffice, however I tried installing DX9 however, it tells me that a newer version is detected therefore cant install.
There are special directives for referencing dlls from fsi. The #load directive loads the .fs file only. You need to use the #r directive to reference the file. You can either use the full path of the file or you can use #I to include the path to the file. More details here. Keep in mind that fsi is completely independent of your project, so all references in your project must be duplicated in fsi for it to access the same types.
I am running a build process and it has failed with this error that I cannot find much about. The error is Error 58, which fails on an object (.o) file. what does this mean?
If you are running on windows: Runtime error 58 usually displays in most Microsoft Windows operating systems. It occurs when Windows cannot insert data into a saved or renamed file that is identical to a file name that already exists in the specified folder.
EDIT: Try doing a clean and getting rid of your intermediate and end files before doing a build. Does it still happen ?
