I solve the problem in that way : I write myself CheckScrollBars(...) method :
void CMyView::CheckScrollBars(BOOL& bHasHorzBar, BOOL& bHasVertBar) const
{
DWORD dwStyle = GetStyle();
CScrollBar* pBar = GetScrollBarCtrl(SB_VERT);
bHasVertBar = ((pBar != NULL) && pBar->IsWindowEnabled()) || (dwStyle & WS_VSCROLL);
pBar = GetScrollBarCtrl(SB_HORZ);
bHasHorzBar = ((pBar != NULL) && pBar->IsWindowEnabled()) || (dwStyle & WS_HSCROLL);
}

If it works for you, then  , thanks for sharing your solution.

I have following problem :
I have condition and in netbeans its saying : warning: assignment makes integer from pointer without a cast
if (var==varb+c) {
sbod='b';}
here is declaration :
char sbod;
float var,varb,c;
any idea what might be worng with my condition ?

I did not understand your problem but as a general note, you must never directly compare floating point values. You will be surprised that it doesn't always work out and lead to subtle bugs. Google about comparing float values in C to find out more.
|
|
|
|
|
ok so is there any way how can I compare two variables which are float , int or other type ?
|
|
|
|
|

Something strange about that message, although I guess you are getting an automatic cast from char to int.
As mentioned in the previous answer, don't use == expressions to compare float values as they are always approximations, unless whole numbers, but even then you can lose precision with very large values.
Just say 'NO' to evaluated arguments for diadic functions! Ash

Maybe Neatbeans is drunk or you reported the wrong piece of code, please check for both possibilities.

I have 4 modelless dialog in a view. Each dialog is having one button. If I click on button I need to display a dialog on the top but it should not be model dialog. So I used
::SetWindowPos(FirstDlg.GetSafeHwnd(),HWND_TOP,2,30,100,60,SWP_SHOWWINDOW ); But problem is:
This dilaog box is having edit control. I am not able to edit in edit control. I am not able to enter anything in edit control.
How to fix this issue.

Are you able to enter text in the edit box when the dialog is shown normal?
|
|
|
|
|
If I create dialog with
m_objGDDlg->Create( IDD_FORMVIEW, GetDesktopWindow());
I am not able to enter but If I create dialog with
m_objGDDlg->Create( IDD_FORMVIEW, this);
I am able to enter but some portion is overlapped with another dialog.
|
|
|
|
|
Do you have any hidden controls on the dialog?

Hi all,
please tell me what is the maximum number of threads that i use in my SDI type application.
its is safe to generate and handle this large number of threads in application,or there is any othre option to handle this.
i have an ListCtrl and this have hundred of items,i want to check all item at same time so i generate thread for each item, but some time there is execption occur when start or stop the thread.
please help me for this.
thanks in advance.

It is not a good idea to have a large number of threads.
You must instead have a fixed number of threads and make use of them for your processing.
As for your question on the maximum number of threads, read this blog entry -

please explain me better idea and approach for this.
if possible please provide me any sample application or example.

Rule of thumb: "If in doubt then use just one thread. If you're really in doubt then use just one thread. If you actually need to waste system resources then use two threads".
On the serious side,

You would experience no performance gain doing this, unless you have a CPU core per thread.

Blocking IO can be a good reason for (over-)threading for performance.

True, but that's not the OP case (or, at least, that doesn't look like the OP case).

Actually he would. I recently put together a little utility that does exactly what the OP wants (I offered it to him but he was not interested). When it had only one thread, it took over 20 minutes to check all of the links (i.e., URLs) in the list (slightly less than 500). When I changed it to check each link in its own thread, the time was dropped to around 2 minutes.

OK. Now that makes sense. Thank you.
