I'd start by looking at the active accessibility (MSAA) interfaces.

Hi ,
I want to add one of my personal folder to the start menu .
Like Recent documents it has to display documents in my personal
folder also.
how can do it?
plz Help me............

Use Windows API (SHGetSpecialFolderPath IIRC) to get the location of the folder "Programs" and create there a subdirectory where you will create a shortcut to your documents.

Hi am an amateaur vc++ programmer.Just started now!I want to know how do i program the follwing:
i have to select an option in my combo box(a question) and the corresponding answer should appear as chioces in 3 radio buttons.Each time I select a question the option in the radio button should change.What functios should I use and where should I use?

CComboBox::GetCurSel() would return the index of the selected item in the combo box.
You can override the CBN_SELCHANGE message. When you get this message set the corresponding radio button as selected.
I hope that I understood you correctly...
Somethings seem HARD to do, until we know how to do them.

in continuation with Anshuman... you have to you have to develop some sort of data structure which will keep you question, 3 choices and correct answer. also you have to associate the radio button with control variable of type CButton.. using CButton::SetWindowText().. you can change text of that radio at runtime when ever new question is selected!

Hi please help us,
We have captcha images with us, we have to remove noise and extract data present in captcha image.
Please give us suitable image processing algorithm or tell us where we can get those algorithms and give some guidance how to approach this task.
Regards,
Balu.

It depends on the type of noise, and on what is the information that you want to extract from the image.
There is not only one type of algorithm,
often the cleaner algorithm can be slitted in more processing step (every time to remove a particular effect).
So, often, you have to write your personal algorithm.
But, of course, you can base your research on some standard processing.
Some keywords:
white noise, gaussian noise, image processing, filters, 2D filters, high pass/low pass, median, segmentation, fft, RGB/HSV image transformation,...
Cheers,
Russell

Russell,
Thanks for your reply.
The noise is nothing but in captcha image there will be vertical and horizontal line. As we all know the captcha image is generated with some irregular lines(noise) and a text on that.
I want extract the text present on the image by segmenting the image and then i have to convert it into string.
Give reply as early as possible that would help us.
Regards,
Balu.

I think that you can use the FFT-2D.
there is a simple way to find a sample image (like a char) on a picture simply matching the FFT-2D of the sample image with the fft of the given image.
The match can be more smart if you compare not simply the fft coefficients, but some coefficients ratio:
if you normalize every coeff by the coeff(0) [at null frequency] you will obtain coefficients that are indipendent from traslations and scalatures. To understand this look at the fft properties, and what happens to the coefficients with different scale, rotations, traslation.
It surely wiil work on this type of images
http://captchas.net/logo.png
your job can became very complex if the char are distorted, you have to understand how is working the distorsion and then find a righ way to recognise the chars.
see this strage deformations
http://en.wikipedia.org/wiki/Captcha
This can give you some ideas.

Thank you Russell, i will check it out with the links u mentioned here.
Please keep mailing if any idea comes and give reply to my message, i will be great full to.
Thanks lot for your quick response.

Ok Russell to remove noise is complex we will keep that one aside.But how to extract characters which are in the captcha image.
One of my friend given a suggestion that we can extract data from image which is present on image using image processing algorithms.Give reply if u have any idea.
Regards,
Balu.

The suggestion to use the FFT2D wasn't to remove the noise, but to extract char from the image.
It will work also with a low level of noise.
If the noise disturbs this processing, you can try to remove it with a pre-processing step, using some segmentation algorithm. I think that a good pre-processing is to find a good way to transform the RGB image in a monocromatic one.
Cheers,
Russell

Thanks Russell,
Your information will help us a lot.We are very much tank full to u.
I will study about FFT2D to remove noise from the image,mean while if any doubts come shall i give reply here or if any personal mail-id u will give to us we send the query to the mail id and it will be help full to us.
Regards,
Balu.

Russell u haven't given ur personal mail id, if u give it would help us if any doubts come tomorrow.
u can understand my problem, if you willing only give...................
Ok Russell, i have to leave my office today we will meet tomorrow.Please mention timings at what time you are available to us.
Iam thinking that positive response i will get from u for this message.

I need to run multiple .bat files(in specific order, sychronously) from my VC++
windows app. I also want to hide the DOS command window so that users don't
see them. what i have to do
Arise Awake Stop Not Till ur Goal is Reached.
|
|
|
|
|
Use ShellExecuteEx. set SHELLEXECUTEINFO-->nShow to SW_HIDE.
|
|
|
|
|
yes i used the shellexecex to run an exe in which i called the batch file inside the exe. here i have to hide the dos window

But, you have not followed , what I said, Following snippet just works perfectly for me,
SHELLEXECUTEINFO ShExecInfo;
ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFO);
ShExecInfo.fMask = NULL;
ShExecInfo.hwnd = NULL;
ShExecInfo.lpVerb = _T("open");
ShExecInfo.lpFile = _T("c:\\Test.bat");
ShExecInfo.lpParameters = NULL;
ShExecInfo.lpDirectory = NULL;
ShExecInfo.nShow = SW_HIDE;
ShExecInfo.hInstApp = NULL;
ShellExecuteEx(&ShExecInfo);
|
|
|
|
|
#include "stdafx.h"
#include <shellapi.h>
int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{
HINSTANCE res = ShellExecute(
NULL,
"open",
"C:\\BatchFile.bat",
NULL,
NULL,
SW_HIDE
);
if (res <= (HINSTANCE)32)
{
MessageBox(NULL, "Failed!", NULL, MB_OK|MB_ICONSTOP);
}
return 0;
}

hi my code is
SHELLEXECUTEINFO ShExecInfo = {0};
ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFO);
ShExecInfo.fMask = SEE_MASK_NOCLOSEPROCESS;
ShExecInfo.hwnd = NULL;
ShExecInfo.lpVerb = "open";
ShExecInfo.lpFile = "C:\\Program Files\\OpenVPN\\bin\\sample.exe";
ShExecInfo.lpParameters = "";
ShExecInfo.lpDirectory = NULL;
ShExecInfo.nShow = SW_HIDE;
ShExecInfo.hInstApp = NULL;
ShellExecuteEx(&ShExecInfo);
WaitForSingleObject(ShExecInfo.hProcess,INFINITE);
inside sample.exe i am having a batch file
Arise Awake Stop Not Till ur Goal is Reached.
|
|
|
|
|
In this case, window for sample.exe will be hidden.
deeps_cute wrote: inside sample.exe i am having a batch file
You could apply same code there ,too. How you are executing those batch files ?
|

deeps_cute wrote: inside sample.exe i am having a batch file
Well you need to change the code in the EXE (sample.exe) to code like mine or yours.
By the way, remember to call CloseHandle on hProcess after you're done with it or you'll leak it.
