I'm trying to get the selected item from a CListCtrl. I intercept the NM_CLICK messge and try the following:
<br />
NMITEMACTIVATE* pNMItem = (NMITEMACTIVATE*)pNMHDR;<br />
<br />
int nItem = pItem->iItem;<br />
int nSubItem = pItem->iSubItem;<br />
<br />
I get the subitem no problem but the iItem is always -1. I'm sure it's pretty simple but I can't figure out what I'm missing. Any suggestions?
Thanks,
Paul

Paul -
Try using the GetFirstSelectedItemPosition method for CListCtrl.
This returns a POSITION which is used in the next call to GetNextSelectedItem (that will return and item number).
Then use the item number in the call to GetItem (you need to send in a pointer to an LVITEM structure).
Here's some sample code...
Hope this helps,
Tim 
CListCtrl myList;
POSITION pos = mylist.GetFirstSelectedItemPosition();
while (NULL != pos)
{
int nItem = mylist.GetNextSelectedItem(pos);
LVITEM lvItem;
ZeroMemory ( &lvItem, sizeof(LVITEM) );
lvItem.mask = LVIF_IMAGE | LVIF_TEXT; //gets the information you are interest in
lvItem.iItem = nItem;
if (TRUE == mylist.GetItem(&lvItem))
{
<do something="" with="" item="" info="">
break; //if you want to stop
}
}

Maybe this will help a bit...from the docs:
"The iItem member of lpnmitem is only valid if the icon or first-column label has been clicked.
To determine which item is selected when a click takes place elsewhere in a row, send an
LVM_SUBITEMHITTEST message."

Hi All,
I get a hang when trying to expand the 'str_vec' variable
(code follows) in the Variables window. It however has no
such trouble when trying to expand the 'int_vec' variable
in the window.
Note that I set breakpoints at the 'display_message()'
and at the while(1) statements and get the same
effect.
Help appreciated.

Can you reformat your post to include all the text in angle brackets <>?
What version of Visual Studio?

I tried it with VS6 and it seemed to work fine.

VC6 had vectors?

Negative. Too cost prohibitive.

Works just fine on Visual Studio 6 for me.

Hi there,
I have an error with this line when initializing a dialog,
this->SetWindowText ("Hi there") ;
The compiler says:
error C2664: 'CWnd::SetWindowTextW' : cannot convert parameter 1 from 'const char [9]' to 'LPCTSTR'
I guess I have something missing but I don't know what.

You are probably building a unicode application - that is the default in VS2005. Try:
this->SetWindowText(L"Hi there");

Looks like you're doing a Unicode build, so the SetWindowText method is
expecting a const wchar_t * but you're passing a const char *.
// better:
SetWindowText (L"Hi there") ;
// best (will work for both unicode and non unicode builds):
SetWindowText (_T("Hi there")) ;

Try this:
this->SetWindowText (_T("Hi there"));

I am really surprised nobody mentioned:
SetWindowText (L"Hi there");
or
SetWindowText (_T("Hi there"));

Hi to all,
I want to send post data to some web page using CHtmlView and Navigate2 function.
This code I am using now:
void CnutritionresultsView::OnInitialUpdate()
{
CHtmlView::OnInitialUpdate();
//Navigate2(_T("www.nutritionresults.co.uk"),NULL,NULL);
Navigate2(_T("http://localhost/wayneextrafunction/"),NULL,NULL);
}
I want to send two post parametars to page http://localhost/wayneextrafunction/
How can I do that.
Best Regards,
Predrag

void CHtmlView::Navigate2(
LPCTSTR lpszURL,
DWORD dwFlags = 0,
LPCTSTR lpszTargetFrameName = NULL,
LPCTSTR lpszHeaders = NULL,
LPVOID lpvPostData = NULL,
DWORD dwPostDataLen = 0 );?
|
|
|
|
|
I know for that function but I don't know how to set lpvPostData argument
|
|
|
|

Document says it is the data expected by the HTTP POST protocol,
May be this information from w3.org[^] is useful
The user agent then conducts an HTTP POST transaction
using the URI `http:
The message body would be (ignore the line break):
name=John+Doe&gender=male&family=5&city=kent&city=miami&
other=abc%0D%0Adef&nickname=J%26D

Hi,
I Created MFC application using VC++6.0.
When i copy this EXE and i pasted in another computer which does not have VC++.
I got the assertion error in Winocc.cpp at line 345.
Please help me....

I'm surprised it even runs if you're missing things.
Search for vcredist.exe or mfc redistributable to find a program which installs all the needed MFC files.
You have tested your file out as a release, rather than a debug executable?
Have you looked back on your developement PC to see what is in Winocc.cpp:345 ?
Iain.
