Hello All~~
Does anyone know how to display the OpenCV image structure "IplImage" in MFC CView?
Typically, many example shows that after we called 'cvLoadImage()', it will call 'cvShowImage' to display the image in another seperate window (as the code below).
IplImage* img = cvLoadImage( argv[1] );
cvNamedWindow( "Example1", CV_WINDOW_AUTOSIZE );
cvShowImage( "Example1", img );
What if I would like to display the image readed by OpenCV 'cvLoadImage' into CView, how can I do that????
Any suggestion, please?????
Thank you very much.
// I found that CImage from MS cannot open PPM file and I would like to use some features of OpenCV so I changed to OpenCV but now I found this problem. Please help. ![Rose | [Rose]](https://codeproject.freetls.fastly.net/script/Forums/Images/rose.gif)

Hi
I'm trying to submit a web form with method=POST parameter.
However, when I run the following code, I'm getting an error saying: "The URL is invalid"
CString strHeaders =_T("Content-Type: application/x-www-form-urlencoded");
CString strFormData = _T("query=murod&a=14");
CInternetSession* pSes=new CInternetSession();
CHttpConnection* pConnection =
pSes->GetHttpConnection(_T("http://www.wutever.com/"));
CHttpFile* pFile =
pConnection->OpenRequest(CHttpConnection::HTTP_VERB_POST,
_T("/news/"));
BOOL result = pFile->SendRequest(strHeaders,
(LPVOID)(LPCTSTR)strFormData, strFormData.GetLength());
What I'm doing wrong?

LOL I found my mistake 
CHttpConnection* pConnection =
pSes->GetHttpConnection(_T("http://www.wutever.com/"));
Looks like I should not include "http://" in the url.
Now another problem:
I'm able to send the request, but how do I get the response? The response will be a web page source?
After sending the request I wrote the content of the pFile(CHttpFile class) to a file and based on that file I'm guessing either I didn't send the request, or either I didn't get the response.
What should I do to get the response?

after calling, CHttpFile::SendRequest
u should call CHttpFile::QueryInfoStatusCode
u will get status code...Http Error Codes...
if status code is 200, then u can download the response using CHttpFile::Read.
response may contain Html content or File Content if u have called to pdf,doc etc.
Regards,
Swapnil

Thanks alot for your reply Swapnil.
CHttpFile::QueryInfoStatusCode is very helpful, thank you! 
That's what I did. I used CHttpFile::Read, and it didn't look like a right response.
Looks like I'm sending wrong headers and/or post data.

ADO, MFC, STUDIO 2008
There is control CListCtrl on a dialog window.
CListCtrl m_listCtrl;
DDX_Control(pDX, IDC_LIST1, m_listCtrl);
m_listCtrl.SetItemState(100,LVIS_SELECTED, LVIS_SELECTED); // choose row 100
How do by programmatically to scroll rows into control
of class CListCtrl?
There are only 7 rows into view area of control CListCtrl.

You should be able to do this using CListCtrl::EnsureVisible[^].

Dir all.
How i can know my progarme run form exe file or release mode of VS.
Example :
...
// run by F5 in VS
#if ! define (ABC) // i try _DEBUG and NDEBUG but it ca not check
messagebox("run by VS");
// run by double click in exe file
#else
messagebox("run by it selft");
#endif
...

First of all, macros are evaluated during compile time, not runtime, your #if !defined... thing will be "built into your exe" when you build your program, and then no matter where you run your program from this won't change your already built exe.
A way you could do this is by giving a command line parameter to your program in visual studio and then checking the existence of this parameter in your exe, if it is there, you runned your program from VS, if it is not there, you runned it by doubleclicking it in an explorer window for example.
Does this help?

Hi,
Is it possible to find out file location using C language in Windows programming?Is there any function in C language which can display the file location?
|
|
|
|
|
Could you please elaborate?
For instance what would be the input of such function?

hi,
i think that if i can found the location of the file so i can give that location of the file to my c program which would act as input.doing this that c program can read or whatever i want.

From your previous post, I may guess you need the file location, given mouse pointer position as input. If you need this the you've to write a shell extension, hence the link I provided.

hi.
firstly i want to say very very thank you. actually i want to do all the work in C .can it is be possible that without writting shell extension which you have provide me i can do all that job?

AFAIK writing the shell extension is by far the simplest way to do it. Michael's articles are really good stuff, have a look at them.

This makes absolutely no sense. If you already know the location of the file, what's the problem?
If the file's path & name are being passed to your program (via a command-line argument), you have access to that using __argv. With that, you can then use _splitpath() to extract the various pieces. Also have a look at PathRemoveFileSpec().

hi DavidCrow,
actually this programming is a part of my project.so don't be confuse.I am now telling you about my project.Actually i have a C program which can read/write a file of extension .docx.means that c program can read/write the *.docx.so first i have to give input to that program .i mean that i have to give name and location of the *.docx file.So for its input i want that when i simply one click on any *.docx file it would be input for that program.Its my project.now i am thinking that when i simply one click on any *.docx file i would be able to know its location by C programming. I think that it should be now clear to you that what i want to ask you...

Do you have a WinMain() function?

Hi DavidCrow,
That *.docx file can be anywhere in my computer.So i want when i would be that location and if i simply one click by mouse, the C program which i mention early starts read it contain.Don't be confuse.
Suppose that file is in D:\files\my.docx location I want to do is that when i click on my.docx file that C program starts reading its contain.If it is in another location the same case would be happaned there.
Ya i have winmain() function and i also include windows.h #include<windows.h>.but further programming related to mouse , i don't know .So please tell me that part of program in detail.please

I told you before: create a file association in explorer. Name your program as the handler for .docx files. Then double clicking will load your program with the filename as an argument, just like clicking a Word-document start Word with the document opened
