File Not Found Exception : Exception from HRESULT: 0x8007007E

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Trying to execute applcations with OpenCV 1.0 and the OpenCVDotNet 0.7
release 
2. Deleting and adding the assembly references also does not solve the issue

What is the expected output? What do you see instead?
Application execution (any application which uses OpenCVDotNet)

What version of the product are you using? On what operating system?
OpenCVDotNet with OpenCV 1.0 on Windows XP Professional SP2 and VS2005

Please provide any additional information below.

The example provided with 0.7 reports that the OpenCVDotNet Assembly of
Version 1.0.2616.4315 is not found and refuses to execute, throwing a
FileNotFoundException

Which version of VC# are you using? I saw something like this happening with 
Visual
Studio.NET 2005.

This is caused by the fact that when working with Visual Studio .NET, the 
search path
of DLLs is not derived directly from the system PATH. Therefore, your app can't
locate cv100.dll which is the main OpenCV dll file.
There are a few workarounds:
1) Tell VS.NET 2005 to look for DLLs in the OpenCV bin directory (done through 
the
Settings dialog).
2) Set the application to execute while the working directory is OpenCV bin 
directory.
3) Copy the DLLs from from OpenCV\bin to %SystemRoot%\System32.

See attached file for an example configuring .NET to run the program from 
OpenCV\bin
directory.

How about we do this copying of DLLs in our OpenCVDotNet library installation?

Pardon me, but MEDIUM?

noone solved this problem ever, its still there and it seems noone cares....

too sad, but we are all to blame for trusting that when someone says something 
works
, it will, and its not our case is it?

for the record, i have the problem and there seems to be no light at the end, 
in my
case, ill just let it go and dont use opencvdotnet cuz it doesnt work, thats it

same problem, no solution..

I installed OpenCV 1.0 and OpenCVDotNet 0.7 and works well, but then I format 
the PC
and install opencv it again, and don't work, install in other pc and don't 
work, then
install opencv in another PC and it works well... 

how i can install it always well?

i think i found a solution to the problem.

For a better understanding i will shortly describe the problem as i understand 
it:

the problem
-----------

The reason for the occurence of the FileNotFoundException with HRESULT: 
0x8007007E
is, that dependencies (other dlls) of OpenCVDotNet.dll can not be found.

some additional info
--------------------

There are two sources for dlls needed for OpenCVDotNet.dll as far as i can see:
 - the opencv dlls
 - the visual c++ 2005 runtime libraries

the solution
------------

To ensure the opencv dlls can be found:

 - install opencv
 - follow the instructions from Comment2 (running the program in opencv/bin solved it
for me)

The solution for missing visual c++ 2005 runtime was:

 - installing visual c++ 2005 express (as found on the microsoft site).

Installing the visual c++ redistributable does NOT solve the problem, as 
OpenCVDotNet
links against the debug version of the c++ runtime, which is not included in any
redistributable file.

Hope this helps!

This worked for me: (I have VS2008)
-----------------------------------

I installed OpenCV first, then installed the OpenCVDotNet second.

I then opened the Examples.csproj in VS2008 and converted it.

I then removed all the references to OpenCVDotNet, OpenCVDotNet.Algorithms and
OpenCVDotNet.UI

I then added these projects from the OpenCVDotNet\src folder and fixed up the
references to be project references rather than the DLL's (converting the 
projects to
2008 as I went). I've found that this is usually the best thing for a number of
projects I work with where I get the FileNotFound exception.

I checked the library paths in c++ and it had found the C:\Program 
Files\OpenCV\lib
folder happily.

I pressed "Run" and off it went.

I've attached my VS2008 solution file and the other bits and bobs that it 
created.

       {
           InitializeComponent();
       }

       private void timer1_Tick(object sender, EventArgs e)
       {
           try
           {
               using (CVImage nextFrame = capture.QueryFrame())
               {
                   pictureBox1.Image = nextFrame.ToBitmap();
               }
           }
           catch(Exception k)

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
   <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

This is the error message i got when running , the application
compiles but run time errors are occuring  am using Visual Studio 2008
with OPENCV 1.0 with the OPENCVDOTNET.

Hi friends 
i have tried all the solution for this error but still not able to solve this 
one..

Looks like that the problem that you are having is about the path of the 
Assemblies
references (in good spanish :P Debugger cannot found the path of the DDL's of
OpenCVDotNet...) (I Think...)

Well, problem is here: 
          capture = new CVCapture(@"..\\..\avi.avi");

You've used COM component to retrieve a file, then @"..\..\avi.avi" is refered 
to 
"c\avi.avi".
