Hello..

This is very simple question but i dont know how to solve it.I am just beginner in this field so please help me.

In my application..I want some input(binary)..

like..

Enter Input Value:<br />
<br />
SEL    Cx0     XOR    D1<br />
1        1        0      1

Here how i can enter 1101 so it will automatically enter Tab button??ie after entering 1(input for SEL),next cursor will be at Cx0( after 8 tab from SEl) and same way for all other input.

Second question is..How can i enter input as a only "Single char"..ie after entering single char(for exam.. 1) then next cursor point will be at Cx0 input point..

Thanks

Dear

Enter Input Value:

SEL Cx0 XOR D1
1 1 0 1

please mention it.

you wants to take input in Edit Box.

if you are using the Edit Box then two ways

1. create your Control dervied from CEdit and handle all input in EN_CHANGE there bcoz u have to take care of binary
also.

2. handle EN_CHANGE od Edit control in Dialog Box.

What is the difference between map and set AND multimap and mutiset

Hey, are you collecting info for the enemy? Big Grin | :-D

From MSDN multimap reference:

<br />
Unlike template class map, an object of template class multimap does not ensure that key_comp()(x.first, y.first) is true. (Keys need not be unique.)<br />

The same diffrence holds for set, multiset pair.

But, what is the difference between map and set?

Re: STL basica

excerpt of MSDN documentation for map:

<br />
The template class describes an object that controls a varying-length sequence of elements of type <big>pair<const Key, T></big>. The first element of each pair is the sort key and the second is its associated value.<br />

excerpt of MSDN documentation for set:

<br />
The template class describes an object that controls a varying-length sequence of elements of type <big>const Key</big>. Each element serves as both a sort key and a value.<br />

Why don't you make a little effort to read documentation, before posting?

Hi,
How you openned the web page using CDHtmlDialog/ CHtmlView, ...?

You can use MSHTML COM objects(IHTMLDocument, IHTMLElement, ..) and change the HTML Text to <Strong> or change the color of text or change the html style of the html element in runtime to highlight the Text. This requires you have to use IE controls in any mean (CDHtmlDialog, WebBrowserCtrl, ...)

Hi,
I can't understand "MFC's method to execute a web page".
My method will work only if you have hosted the IE web control in your application.

You "execute the web page" ? Does it uses Internet Explorer window.
Is this Web page is shown in your application.

Sorry I can't understand your setup. Are you showing the web page? in your application window.

how to move a software developed with vc6 to vista?

I have almost finished developing a software with vc 6. Then my leader suddenly told me that this software should be also be able to run under Vista. I know it is hard to accept, but it is the fact. I think the fastest way maybe convert it to vs.net 2005. But it is not such easy. It showed a lot of errors.Could onebody give me any suggestion. To write a new software with vs.net 2005, or convert it, or some other good idea.

VC6 is rubbish, you shouldn't use it anyhow, if you have the option.

If you get a lot of errors, you should work through them, you will, in the process find out ways in which your old code is not standards conformant.

I would, however, just test to see if the app runs on Vista. I don't see how moving to VC2005 would magically cause this to occur.

why do you say VC6 is rubbish?

I've had nothing but problems with VS2005, even though I applied the service pack 1 and then the vista pack as well. I still can't get add member variables to work properly, and miss the old right click class wizard in VC6.

I can still get to the class wizard/add variable but when I click control type variable all the other fields still stay empty and are unusable.

That may not make your application to run as expected[edit]on vista[/edit]. As there are other platform issues involved there, like , way to deal with registry.

VC6, is not strictly adheres to C++ standards, and no longer supported by Microsoft. So , better migrate to higher version of compiler.

Those errors have nothing to do with Vista. They are the result of VS2005 being more C++ compliant.

Hi,
I just want to know that is there any MFC or ATL class for regular expression search or validation? If not, what are the other alternative?
I don't want to use .Net or anything which needs framework to be installed on client machine.
Looking for any help, suggession.

Thanking you,

Handling WM_NCPAINT

Hi,

I have some problem in handing the WM_NCPAINT. As per MSDN, the dc with the region clipped can be obtained as follows for handling the WM_NCPAINT.

case WM_NCPAINT:<br />
{<br />
    HDC hdc = GetDCEx(hwnd, (HRGN)wParam, DCX_WINDOW|DCX_INTERSECTRGN);<br />
}

But when I tried this am getting hdc as NULL. Any solution for this issue.

N.B - I tried using the DCX_CACHE flag in the GetDCEx() function. Eventhough in this case it returned a dc handle, the clipping is not proper.

Thanks
Naveen

Is wParam == 1 when GetDXEx() fails?

If not, try calling GetLastError() when it fails and see what the error code is.

converting int* to int

Hi all,

I am making a multi threaded application in which i have made a UI thread and from that thread i m using SendMessage() function to send a message to be displayed like this.

int row_no = test_int;
m_pLogWnd->SendMessage(MSGDIS, (WPARAM)(CString*)&logmsg,(LPARAM)(&row_no));

and recieving that message in my main class function like this..

LRESULT CMonitorVw::OnDispMessage(WPARAM wparam, LPARAM lparam)
{
	CString* pLogMessage = (CString*) wparam;

	int *u = (int*)lparam;

	m_obj->m_List.SetItemText(u,7,*pLogMessage);

	return UpdateData(FALSE);
}
<\pre>

if i do this i am getting an error

SetItemText' : cannot convert parameter 1 from 'int *' to 'int'

either tell me the way to convert int to int* or in any other way i pass or recieve inter value.

Thanks in advance

Actually you don't to pass an integer pointer, you may pass directly the integer value:

m_pLogWnd->SendMessage(MSGDIS, (WPARAM)(CString*)&logmsg,(LPARAM)row_no);

and

  LRESULT CMonitorVw::OnDispMessage(WPARAM wparam, LPARAM lparam)
{
  CString* pLogMessage = (CString*) wparam;
  int u = (int)lparam;
  m_obj->m_List.SetItemText(u,7,*pLogMessage);
  return UpdateData(FALSE);
}

BTW usually pointers are passed only as LPARAM (though maybe an issue only on very old Windows versions).
