Actually, you can use GetWindowText on windows which belong to a different process.

Well, read the subject line of the post again and you'll find it mentions "window control".
Then have a look at the documentation I linked to in my post where it clearly says "GetWindowText cannot retrieve the text of a control in another application".

But, then I'm just assuming the OP really meant a control when he wrote it....

Please read the whole conversation before adding your comments. We're talking about a control that is owned by another process.

I did read the whole conversation, but maybe i misunderstood something...sorry about that...
I thought by "window control" you meant things like buttons or edit boxes on windows, and as far as i know you are able to get the text of those, or at least some of them, some controls, like buttons allow you to query their windowtext over process boundaries, while some don't. But i guess you meant something else, sorry... Frown | :(

No worries, there's no need to apologise if you have read the whole conversation before adding your comments.

You can have a look at the Remarks section of the respective documentation page[^] to know what I'm talking about.

Modify your Manifest property from

Project Properties->Linker->Manifest file
Change UAC Execution Level to "Require Administrator".

See this[^]

So...you want your application to run with full administrative rights without the user knowing that it's running as administrator. Sounds a little insecure to me...which is probably why MS don't let you do it.

Anyway - this page[^] has a workaround, of sorts.

sotring/comparing strings

Hi to all.
I'm trying to sort strings which contains some eastern European specific letters.
I'm sorting with qsort function:
qsort( (void *)polje, (size_t)cnt, sizeof( char * ), compare );
where 'compare' is a helper function int compare( const void *arg1, const void *arg2 ) which uses '_stricoll' function.
Wen running my test app sorting doesn't work.
I then tried to set local settings like this on OnInitDialog():

char* locale;
locale = setlocale(LC_ALL,"Croatian");

locale returns "Croatian_Croatia.1250"; but sorting still isn't working, why?
Thanks in advance

Stuart Dootson30-Mar-09 2:08

All I can suggest is splitting the problem into smaller parts. First, check that _stricoll (and thus your compare function) compare strings as you would expect.

After that...well, can you confirm that polje is of type char* polje[], i.e. an array of character pointers?

Thanks for replay, code:

CString *polje = new CString[cnt];
for(int i=0; i<cnt;i++)  {
    CString pom;
    m_List.GetText(i,pom);
    polje[i] = pom;
}
qsort( (void *)polje, (size_t)cnt, sizeof( char * ), compare );

I have a list box control where user can add strings for sorting. Posted code is extracted from OnOK()!

Stuart Dootson30-Mar-09 2:25

Stuart Dootson

30-Mar-09 2:25

Right...well, that sizeof(char*) in the qsort call isn't going to be correct, is it?

I would suggest:

Change compare so it expects its two parameters to be pointers to CString
Change the sizeof( char* ) to be sizeof( CString )

And here's a thought - if you used STL containers, you could use type-safe algorithms and things that would highlight these issues...

std::vector<cstring> polje(cnt);
for(int i=0; i<cnt;++cnt)
{
	CString pom;
	m_List.GetText(i,pom);
	polje.push_back(pom);
}
std::sort(polje.begin(), polje.end(), compareFunction);</cstring>

Hi,
I have created a ListBox control with Selection type as Multiselection. Can I know how to handle Ctrl and Shift keys while making a selection in ListBox items. ie.,If I press Shiftkey on a item and select another item than all items in between both items should be selected. If I press Controlkey on a item and select another item then only the two items should be selected.

Thanks..

I thought CListBox already did this?! Have you enabled multiple-select option?

I have enabled Multi-select options. It is infact selecting multiple items. I need the following behavior

Items in listbox:

Test1
Test2
Test3
Test4

I select the Test1 item in the listbox , I press shift key and now select Test4 item. Expected behavior is Test2 and Test3 should also be selected.

Where as If I had pressed Ctrl key instead of Shift key then only Test1 and Test4 should be selected.

Rajesh R Subramanian30-Mar-09 0:43

I am able to see this behavior if I set "Extended" style for the list box's selection style.
