u can do debuging in a release version too

set the following option in project settings

take project->Setting

now take c++ tab
in the optimization combobox select Disabled
in the Debug info combo select "Program database for edit and continue"
now take the Link tab
Tick the check box "Generate debug info"

now rebuild the project

Hi

I have a property sheet with tabbed property pages

When the property sheet is opened up, depending on some user settings some pages
are not displayed

When the property sheet is created, i add all the pages

the in OnInitDaig, i remove the pages i dont need with

RemovePage(&m_Page1);

this works fine, if i only open the sheet up once

If i try to open again, i get an expection error on RemovePage line, it seems the second time around
the page doesnt exist, how can i check so that the second time the sheet is opened up it doesnt try to removepage which has already been removed

anyone any ideas

thanks

if(m_Page1)<br />
{<br />
  RemovePage(&m_Page1);<br />
  m_Page1=0;<br />
}<br />

and check m_Page1==0 before RemovePage API

A_Laxmanm_Page1=0;

i think m_Page1 is an object of class derived from CPropertyPage

in that case how can we assign like this?

Yeh, you are right..we can't
I think we can solve the problem by maintaining the flags for pages. Smile | :)

I'm curious why you don't just call AddPage() for the pages you want added, rather than add them all and remove the unwanted ones.

If i try to open again,

Does the sheet get closed or hidden? How does it get re-opened?

CompareFileTime problems

Trying to compare a date to see if it is earlier of later.
My CompareFileTime function returns junk.. 0xffffff.

FILETIME Time;
SYSTEMTIME stime;
FILETIME ftime;

GetSystemTime(&stime);
BOOL bSys = SystemTimeToFileTime(&stime, &ftime);
LONG lfiletime;
FileTimeToLocalFileTime(&FindFileData.ftCreationTime,&Time);
//Time = &FindFileData.ftCreationTime;
lfiletime = CompareFileTime(&Time, &ftime);

0xFFFFFFFF is the same as -1, and -1 is a valid return value from that function. Are you sure you are getting the wrong result?

Peace!

Well, i check for -1, 1 or 1. In which case my algorithm totally misses the result. How would i catch it, would i have to check for 0Xffffff? Or does the computer know to equate that to -1?

0Xffffff is the hexadecimal representation of -1. So you can simply check for -1, this is exactly the same.

Post the rest of the code that evaluates the result, as well as a step-by-step of what you see in the debugger as those lines are executed.

displayiing a Dialog over a Dialog

Did you saw MSDN for CompareFileTime
In MSDN
"Return Values
–1 indicates that the first file time is less than the second file time. 0 indicates that the first file time is equal to the second file time. +1 indicates that the first file time is greater than the second file time.
"

I am displayiing a Dialog over a Dialog using
MyDlg->DispDialog.DoModal();
only the second Dialog (DispDialog) is displayed. How i can display both the Dialog same time. The Size of second Dialog is more than first Dialog.

If you only need to have your first dialog visible (without having to inject inputs), then you can simply use MoveWindow for the second dialog.
If it needs to receive user inputs, then you need to use modeless dialogs. You can have a look at this tutorial[^]

Are you doing this on the click of OK button?
What happens to the first dialog? Does the dialog close or something else?
If you want both dialogs to show and respond to user inputs create Modeless dialog as A_Laxman and Cedric suggests.

Somethings seem HARD to do, until we know how to do them.

try like this

if( MyDlg->DispDialog.m_hWnd == 0 )
MyDlg->DispDialog.Create( ... )
MyDlg->DispDialog.ShowWindow( SW_SHOW );
MyDlg->DispDialog.DoModal();

If you are displaying the dialog on click of another button the you can just do the DoModal() for another dialog and don't close the first one..
and If your dialog on top is covering first dialog then you can set the position of dialog by SetWindowPos.

If you Need to handle both the dialogs at same time you need to create them modeless

Hi,
I have to run two applications at a time.And I am having button in both application toolbar to switch between two applications.
i.e., If iam running first application,by pressing one button i switched to second apllication,but first appl has to in running mode.The samething has to be done in second application.
The process is same like that (Alt+Tab)in normal windows.
How can i do this?

14-Jun-06 1:43

Two different windows...
These two applcations are two different EXEs of vc++ program.

see me14-Jun-06 1:55

see me

14-Jun-06 1:55

while pressing button of first window

pFirstWnd->ShowWindow( SW_HIDE );
pSecondWnd->ShowWindow( SW_SHOW );
::SetWindowPos( pSecondWnd->m_hWnd, HWND_TOP, 0, 0, 0, 0, SWP_NOMOVE|SWP_NOSIZE );

while pressing button of second window
pSecondWnd->ShowWindow( SW_HIDE );
pFirstWnd->ShowWindow( SW_SHOW );
::SetWindowPos( pFirstWnd->m_hWnd, HWND_TOP, 0, 0, 0, 0, SWP_NOMOVE|SWP_NOSIZE );

try this and tel the result

The query actually was that there are two different exe's running and then you want to achieve alt+tab feature as in windows.
So how are you going to get the pointer (pSecond) in the first application and same for the other one.
Your code seems to work when you have two dialogs in the same application.
Isn't it ?
Correction:// And Cedric also mentioned this in his post
