Could anyone who are good in image processing give me some advises for my question:
1. How to do an 'edge detection' on a bitmap?
2. How to change the contrast of a bitmap?
thanks you.

|
1. apply a convolution filter (see "Laplacian")
2. to raise contrast, lower the low pixel values, raise the high pixel values. to lower contrast, do the opposite.

dear all,
how can i get the handles of controls present in my dialog.
thanx
|
|

hello,
I don't know exactly what you want but:
1. if you are programming MFC and you need a CWnd pointer to an edit box(his resource id is for example IDC_EDIT1) or any other control in your dialog (dialog1) :
dialog1.GetDlgItem(IDC_EDIT1);
2. in old windows programming style
GetDlgItem(dialog1, IDC_EDIT1);
where dialog1 is a handle to your dialog and IDC_EDIT1 is the resource id of the control
for both functions the return value is what you want....

thanx a lot _crs_
thats exactly what i was asking for,
but how do i get the handle of dialog box (dialog1 in ur example)
|
|
|
|
|
Use CWnd::GetSafeHwnd() for any window.
|
|
|
|

... if you are in DialogProc - it looks like this
LRESULT CALLBACK DialogPROC(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam);
handle to the dialog is "hDlg" your first parameter
when you create a dialog ...
DialogBox(hInst, (LPCTSTR)IDD_DIALOG1, hWnd, (DLGPROC)DialogPROC);
where "hInst" is the application instance,
"hWnd" is a handle to parent dialog window in your case will be main window
"IDD_DIALOG1" is the dialog resource id and
"DialogPROC" is the dialog callback procedure (like WndProc for your main window)
if you use MFC look at the other answer ....

I have downloaded the demo project "Review of the network adapters parameters"
by Serge Baza
from site: www.codeproject.com
And the guideline tell that
"You need to include in the program the following header files besides the standard: Iphlpapi.h, IPIfCons.h, Winsock2.h. And it is also necessary to include in the project such libraries as: Iphlpapi.lib and Ws2_32.lib."
but i could not find any attach file as show above.
so I really can not build and run this project.
Please help me !!
Thank you verry much.

This program works for me in VC7 but not
in VC6 so I guess that is what you have.
What exactly do you need? Only your IP?

dear all,
1) i've created checkbox controls at runtime (number of controls can vary).
now how can i access the controls after they r created. how can i verify whether the controls r checked or not.
2) i also have 2 buttons on the dialog. how can i specify their positions and size from my code.
thanx
|
|
|
|
|
the 2 buttons are created during design time
|
|
|
|
|
1) for (int i=0;i< nButtonCount;i++)
IsDlgButtonChecked(IDC_MYCHECK_BASE + i)
2) m_button1.SetWindowPos(...)
|
|
|
|
|
thanx can u plz. tell me how do i get m_button1
|
|
|
|

It's a control variable, most likely created by ClassWizard.
|

Create an array of pointers to buttons:
CButton* m_btns[10];
m_btns[0] = new CButton;
.
.
.
.
delete m_btns[0];

Hello all,
I have a big problem and I don't know why.
Here is my problem:
I have a large project with unicode supported. When I build it as Debug configuration, everything is OK and my app runs correctly. When I build it as Release configuration, the linker complains:
LINK : warning LNK4075: ignoring /EDITANDCONTINUE due to /INCREMENTAL:NO specification
LINK : warning LNK4098: defaultlib "mfc42ud.lib" conflicts with use of other libs; use /NODEFAULTLIB:library
LINK : warning LNK4098: defaultlib "mfcs42ud.lib" conflicts with use of other libs; use /NODEFAULTLIB:library
LINK : warning LNK4098: defaultlib "msvcrtd.lib" conflicts with use of other libs; use /NODEFAULTLIB:library
LINK : warning LNK4098: defaultlib "LIBC" conflicts with use of other libs; use /NODEFAULTLIB:library.
I ignore these warnings and try to run my app. Then, my app hangs when calling OpenDocumentFile(NULL).
I really don't know why the linker uses *d.lib during the linking process.
After that I use /NODEFAULTLIB to ignore these lib and the linker complain again:
LINK : warning LNK4075: ignoring /EDITANDCONTINUE due to /INCREMENTAL:NO specification
LINK : warning LNK4098: defaultlib "mfc42u.lib" conflicts with use of other libs; use /NODEFAULTLIB:library
LINK : warning LNK4098: defaultlib "mfcs42u.lib" conflicts with use of other libs; use /NODEFAULTLIB:library
LINK : warning LNK4098: defaultlib "msvcrt.lib" conflicts with use of other libs; use /NODEFAULTLIB:library
I ignore these warning and try to run my app. Then, my app cause a DEBUG ASSERTION. It is so STRANGE because I build my app under Release mode.
Please give me some ideas.
Thanks in advance.
