When I read about the bug last week, dummy me thought they'd already fixed it. However, for controlled data, I don't think it's a problem.

Why are you doing this? Is this a modal dialog?

Try exiting the dialog using EndDialog(). Also, sometimes it is helpful to look at the code the error message is pointing you to, in this case winhand.cpp/line 229. And by the way,

Halawlaws wrote:

The software is not exiting like it is supposed to. The software is aborting becuase of a debug assertion failure. If, for example, when exiting this dialog you were supposed to return to another part of the program, your software would still completely exit.

I can't tell anything more without actually seeing some of your code. Hope this helps!

How to set different titles for views of the same document

Hi there,
I have in my application a window in which I open files for edit. I present them in a tab style when there is more than one window open (similar to the source browser window in Visual Studio). what I'm trying to do is changing the name of the tab for views which are of the same document. Unfortunatly, I have no success till now.
First I try SetTitle() but ofcaurse that causes to all of the tab titles related to the same document to be changed.
Then I tried to do the following steps:
I add in
1. CChildFrame::PreCreateWindow(CREATESTRUCT &cs) :
cs.style&=~(LONG)FWS_ADDTOTITLE;
2. CMyView::OnInitialUpdate() :
GetParent()->SetWindowText("temp");
but it made no effect on the title.

How can I change the title of those tabs ? From where those tabs take the data for the title ?

I really need your help here,
thanks,
yaron.

Try overriding OnUpdateFrameTitle (undocumented) in your CChildFrame. Look at the standard implementation of CMDIChildWnd::OnUpdateFrameTitle in MFC source files to get a hint on how to implement it.

Hope that helps,

Problem With Date Conversion

Hello,

I have a CString variable with a date and i want to extract the day.

My problem is that i don't know the regional settings of the machine (for example if date is yyyy-mm-dd or dd-mm-yyyy) so i can't use for example .left(2)

I want to know if i can access to the regional setting format date in C++ or how to convert a CString into a date.

Thanks

Using the win32 api, you could do something like this snippet here:

char caData[256];

caData[0] = 0;
GetLocaleInfo(LOCALE_SYSTEM_DEFAULT,LOCALE_SSHORTDATE,caData,sizeof(caData)-1);
m_cShortDateFormat = CString(caData);

char *p = caData;
while (*p && *p == ' ')
  p++;

switch (*p)
  {
    case 'd':
      m_cClientFormValidationDateFormat = "D/M/Y";
      break;
    case 'Y':
      m_cClientFormValidationDateFormat = "Y/M/D";
      break;
    case 'M':
    default:
      m_cClientFormValidationDateFormat = "M/D/Y";
      break;
  }

onwards and upwards...

Something like:

CString strDate;
COleDateTime date;
date.ParseDateTime(strDate, VAR_DATEVALUEONLY);
TRACE("Day = %d\n", date.GetDay());

How to avoid from ListCtrl flickering???

Hi,
I'm using ClistCtrl to display some data I'm receiving.
I need to display only the updated data,so the old data will disappear when there is new data to display(i get new data every 200msec).
The problem is that my ListCtrl is flickering when I'm calling
MyList.DeleteAllItems() function(I'm doing it with timer event).

How can I avoid this annoying flickering?

With best regards,
Eli

Instead of using DeleteAllItems(), use CustomDraw message handler and in that one include to DeleteAllItems() and insert the new data.

Hi Neelesh,

Thanks for your prompt reply.
Do you have any example how to do this?
How should I use the CustomDraw message handler?

How about a call to SetRedraw() before and after the insert/delete operations?

I'd try this first:

SetRedraw

If you still get flicker, try drawing offscreen:

Flicker free drawing of any control

You can disable the painting on the list control with SetRedraw(FALSE);
I'm using this technique when updating my list controls.

m_lstCtrl.SetRedraw(FALSE);
m_lstCtrl.DeleteAllItems();
//Add all new items
...
m_lstCtrl.SetRedraw(TRUE);
//you might need this to force the redraw to happen faster:
//m_lstCtrl.UpdateWindow();

IMO this is easier than trying to implement Custom or Owner Draw
