Hi ,
I would like to sort items contained by my columns into a CListCtrl when I click on the column header. There is a lot of example out there but they are all for Dialog App. How can I do this if I have a ClistCtrl into a CFormView? Up to now, It doesn't work.
I tried to catch message into my CformView class with OnNotify or OnChildNotify, but It don't seem to work.
Thanks for helping

Everything's beautiful if you look at it long enough...

A list control is a list control, whether it's on a dialog or a form view. Assuming you are not already, you need to be processing the LVN_COLUMNCLICK message. Otherwise, provide a code snippet of what you are trying.

Hi!
I tried to catch it with OnNotify() but I'm not sure how to use it.
I tried this, but It's doesn't work:
BOOL CDataBaseManagerView::OnNotify(WPARAM wParam, LPARAM lParam, LRESULT* pResult)
{
NMHDR *pHdr = (NMHDR*)lParam;
if(pHdr->code == HDN_ITEMCLICK)
{
// Do my stuff over here.
}
return CFormView::OnNotify(wParam, lParam, pResult);
}
thanks

Did you ever get this working? I'm trying to do the exact same thing...

What I posted is working code. You'll have to be more specific.
|
|
|
|
|
Ok, here's more specifics. I'm trying to get my list control to sort on a column heading click. You code just handles the click message. Do you know what additional code I'd have to add to get the list view to sort by the column heading that was clicked on?

You'll need a handler for the LVN_COLUMNCLICK notification. In the handler, the column clicked is obtained like:
void OnColumnclick(NMHDR* pNMHDR, LRESULT * )
{
CWaitCursor cursorWait;
NM_LISTVIEW *pNMListView = (NM_LISTVIEW *) pNMHDR;
if (m_list.GetItemCount() > 0)
{
m_nSortColumn = pNMListView->iSubItem;
m_list.SortItems(CompareFunc, ...);
}
}

Hi All,
I need to integrate MapPoint software into my MFC database application. Basically what i want to acheive is to
get the data from the database and display it in the map. Application has to invoke the map and draw the route on it.
Any ideas will be appreciated.
Thanks,

What is the value of lSize?
|
|
|
|
|
Its correct.Equal to file size.

I tried your code and lSize and i have the same value.
|
|
|
|
|
Yes,Same here.

|
|

|

Ok, so what's the problem? You instructed it to read lSize bytes and it read i bytes, both of which were the same.
|
|
|
|
|
Thw point is that svRead does not contain all datas.

How do you verify this? Does a byte with value of zero at the fourth or fifth position confuse your viewer?
My opinions may have changed, but not the fact that I am right.

|
|
Yes,I guess this is the problem.

Don't use fopen() or the other C runtime file functions from <stdio.h> for reading binary data. They're only designed for use with text files.
Under Windows, use CreateFile() to open a file and ReadFile() to read data from it. You can also use the _open() function and _read() to read from the file, which may be more portable (the POSIX binary functions are named open() and read()).

Where did you get this from? fopen(), fread(), fwrite(), and fclose() operate on both text files and binary files. They always have.

Don't you have to add a flag or something in order to read binary data?
Perhaps not with the fXXX() family... I don't have MSDN near my hands so I can't check if it is so.

b means binary.
Anyway,I find out that was problem with debugger.It contains correct value but debugger can't show it.

Have you tried using any of the m-type symbols in the watch window?
I use these two quite often:
m
ma
I've never used these:
mb
mw
md
mq
mu

If you have access to CodeProject, you have access to MSDN[^]

True, but I don't waste any time and money of big loadings at MSDN online with my damn modem!
