It depends on what you're trying to do.
My guess is that you want to know when the user selects another tab in the control.
If I guessed correctly and you're using CTabCtrl you have to write a message handler for the WM_NOTIFY message sent from the tab control with the TCN_SELCHANGE control code.
Use ClassWizard to add a message handler for this. Afterwards you message map should have an entry looking something like this:
ON_NOTIFY( TCN_SELCHANGE, IDC_TAB, OnTabChanged ) ...and a message handler looking similar to this:
void <YourDialogClass>::OnTabSelchange( NMHDR* pNMHDR, LRESULT* pResult )
Have a look att the MSDN sample FIRE[^] to see how it's done.

These are just guesses but maybe it helps: Check WM_NCACTIVATE and also the Frame Window of the dialog (i hope CDialog has one)
CChildFrame::OnNcActivate(...) worked for me with CView based class in a MDI environment.

I also tried the above suggestions already, still no good.
Thanks for the replies though.  I really appreciate them.

May be you are looking for OnShowWindow(BOOL ) or something like this will be called everytime the window is sabout to be shown or hidden.

OnShowWindow still doesnt work.  Thanks for the reply though.

How can i Sum Rows in column 3 i have selected ?
ok,this code sum all rows in all columns :
int nSum = 0;
for( int nRow = 0; nRow < m_list1.GetItemCount();nRow++)
{
for( int nColumn = 0; nColumn < 3;nColumn++)
{
csText = m_list1.GetItemText(nRow ,nColumn );
nSum += atoi( csText);
}
}
csText.Format("%d", nSum);
m_sum.SetWindowText(csText);
I have added Checkboxes to CListCtrl to select witch rows to Sum,ALL I WANT IS TO SUM ROWS IN COLUMN 3 THAT I HAVE SELECTED !!!
HOW ?

And how would your code know which item is checked 
Somethings seem HARD to do, until we know how to do them.

OK, but it works for col 2 but I WANT to select witch rows to sum
HOW? i have try this but it sum all rows in column 2!
:
CString csText;
for(int i=0; i<m_list1.getitemcount();i++)
{
="" if(m_list1.getcheck(i))
="" {
int="" nsum="0;
for(" int="" nrow="0;" <="" m_list1.getitemcount();nrow++)
{=""
cstext="m_list1.GetItemText(" nrow,="" 2="" );=""
nsum="" +="atoi(" cstext);
}
cstext.format("%d",="" nsum);=""
m_sum.setwindowtext(cstext);=""
="" }
="" }
how="" can="" i="" sum="" only="" that="" rows="" have="" select="" ?=""

Hi Bravoone,
Try pasting this code in the first for loop
int nSum = 0;
for( int nRow = 0; nRow < m_list1.GetItemCount();nRow++)
{
for( int nColumn = 0; nColumn < 3;nColumn++)
{
if(m_list1.GetCheck(/*index of item*/nRow))
{
csText = m_list1.GetItemText(nRow ,nColumn );
nSum += atoi( csText);
}
}
// Rest of the code.

 Are you kidding ? I think the erro message is pretty clear no ? You are using nColumn in your code and it has not been declared anywhere. BTW, when somebody gives you code snippet, it is always better to try to understand what it does so that next time you can do it yourself, instead of blindly copy/pasting into your own code.
If you tried to do that, maybe with all the answer you got you would probably have had a working solution. Don't expect people to do everything for you.

Is there a way to build a static library that could be used on both Windows & linux OS?
|
|
|
|
|
you mean something like ACE[^] library?
nave

|
|
|
|

No, the way it is done generally is that the same code is compiled with two different compilers: one for windows (and it produces a .lib file) and one for linux (it produces an .a file if I remember correctly). You cannot use the same library under windows and linux, because a library contains object code which is not portable.

Thanks for the quick reply Cédric. [ ]

You're welcome.
BTW, if you want to compile both for windows and linux (the way I described in my first answer), your code shouldn't use any platform dependant API (like MFC or WIN32 API). But cross-platform solutions exist, like for example ACE (as already said by Naveen) or wxWidgets[^] (something very similar to MFC but cross-platform).
|
|
|
|
|
Yes Cedric, I have taken care not to include any platform dependent code inside the code. Now I just need to build and link the code to diffenent runtimes on respective platforms.
