Hi Friends,
I am working on one Image processing application where I am capturing the Image of the circular object and by edge detection I am getting the periphery of that circular object.
Now I want to find out the radius of the same circular object, can any body guide me how to find the radius of the circle.
Regards,
Dinesh.

this is more a math question.
if you know the periphery length (let's call it P), then you can do this :
P = 2 * pi * r
r = P / ( 2 * pi)
with r beeing your radius

Unlike tox, with that I understand that you have access to the points representing the circle on the screen. If you really have the periphery length, then have a look at his post.
If you have "captured" a set of points defining the circle, simply look for min and max coordinates in each direction (let's call them xmin,xmax,ymin and ymax), then :
radius = (xmax - xmin)/2 or = (ymax - ymin)/2 (both values should be the same).
center point of the circle is (xmin + radius, ymin +radius), for instance.

I think words like 'destiny' are a way of trying to find order where none exists. - Christian Graus

What is exactly a grid control application ? An app that uses a grid control ?
If you want a good grid control, take a look at this article[^]

I am trying to create a UDP connection using the CSocket class. The code I have so far is this:
<br />
CSocket sock;<br />
<br />
if (!sock.Create(0, SOCK_DGRAM, NULL))<br />
{<br />
<br />
GetSocketError();
return -1;<br />
<br />
}
<br />
<br />
if(!sock.Bind((UINT)4200, _T("127.0.0.1")))<br />
{<br />
<br />
GetSocketError();
return -1; <br />
<br />
}
<br />
<br />
The call to Create() works without a problem but when I try to bind to the port and address I get an "Invalid Argument (10022)" error.
Any suggestions?
Thanks.

Did u see what does error 10022 mean?

Yes... it's an "Invalid Argument" error:
WSAEINVAL
(10022)
Invalid argument.
Some invalid argument was supplied (for example, specifying an invalid level to the
setsockopt function). In some instances, it also refers to the current state of the socket - for
instance, calling accept on a socket that is not listening.

why dont you try with NULL as the second parameter?

Hi,
What required to run an application, which is coded in Microsoft Visual Studio 2005 VC++, on other system without Microsoft Visual Studio 2005 installed?

That depends - does it use MFC ? Does it use the C standard library ? Is it statically linked ? Does it use the .NET framework ? Basically, there is a merge module that has all the stuff you may have used, apart from the .NET framework, and because of WinSXS, you need to use that anyhow, you can't just ship dlls anymore.
Actually, it's an exe, and it's called vcredist_x86.exe. There are merge modules you can use instead, your choice, depending on how you distribute your app.

I installed "vcredist_x86.exe" on other PC & then try to run my application. But same error occurs. I have also installed "Microsoft .NET Framework Version 1.1 Redistributable Package" on that PC.
What might be the problem?

You realise I told you every possible thing because you've not told me what the error is, so I'm guessing, right ?

Why ?
Aniket Salunkhe wrote: .Net VC++ 2005
That'd be .NET 2.0. 1.1 is useless to you.

error is : "This application has failed to start because application configuration is incorrect. Reinstalling application may fix the problem"

Does this program use .NET ? It sounds more like a manifest problem. Could the program have other dependencies ? What does it do ?

My .Net application is converted from VC++ 6.0 and some GUI changes are made on that.
My VC6 Application is running properly on any PC.
My .Net Application is running properly on other PC having .Net 2005 installed.
Also when I checked a sample .Net VC++ Application (only displaying the default dialog) to run on other PC without .Net installed , same error was generated.

OK, your app is not using .NET. It seems you're missing a library, such as the MFC80 library, or MSCVRT80, both of which I thought came with that exe.

No. I know about those libraries. The error for those libraries is different. And also I have copied libraries MFC42D.DLL, MFCO42D.DLL, MSVCRTD.DLL alognwith exe during installation.

NEVER distribute the debug dlls, or a debug build. That's not what they are for.
You're not giving me much to go on here. Are you copying the manifest file with the app ? That's the appname.exe.config file.

No, I am not copying the manifest file. Where should I copy this?
You are talking about some libraries, which libraries should I copy & where to copy thos libraries?

It doesn't have appname.exe.config file. In Debug mode it has appname.exe.intermediate.manifest & appname.exe.embed.manifest; while in Release mode it has appname.exe.intermediate.manifest.
The application is MFC Application in .Net 2005.

Hi,
Sorry to distrub you. But it's very urgent for me. Plz help me.
The previous error is now removed.
I changed following Configuration Propeties of Project ( in Both Mode : Debug & Release Mode)
1. Manifest Tool -> Input & Output -> 'Embed Manifest' = No
And/Or
2. Linker -> Manifest File -> 'Generate Manifest' = No
For Release exe:
Then the error was "This application has failed to start beause "MFC80.dll" was not found. Re-installing them application may fix this problem"....then I copy "MFC80.dll" file. Then same error for "MSVCR80.dll"..so copy this copy with exe.
After that 'MS Vicual C++ Runtime Library' error occured as " Appl. has made attempt to load the C runtime library incorrectly. Please contact the appl's support team for more information" & "The appl failed to initialize properly(0xc0000142).Click OK to terminate the appl.)"
For Debug exe:
There was error for file "MFC80.dll" & "MSVCR80.dll", so I copy thos files. Then I run the appl., but still error as "The appl failed to initialize properly(0x80000003).Click OK to terminate the appl.)"
But sample application run propely after copying required file. What should I do for my Application?
Plz, hlep me.
Regards,
Aniket
