Hi all,
i'm trying to isert a new item to the tree control when i click on a button.It's working fine if i'm inserting the new item as a child to the another item which is already having child items,but when i try to add the new item to a leaf item (leaf item as parent to the new item)new item is inserted but not visible.
How can i come out from this problem.Any one please help me .
Thanks in advance.

Try calling - YourTreeCtrl.Expand(hParent, TVE_EXPAND)
where "hParent" is the leaf which is now the parent of the new item

Thank you for your reply Mr GuyM
I already tried in this manner but the item was not visible .Any alternative to this .

//I have a problem reading a text file which I have

void main () {
ifs is ("c:\\test.txt");
wint_t c;

}
}
//The output was:
//..T.e.s.t.
//Note that the loop went for 10 times while I expected it

//The following is an equivalent C program that does all correctly.

Unicode Text File c:\test.txt contents:
"Test" (without quotes).
wchar_t is defined as unsigned short as it should be.
typedef unsigned short wchar_t;
But wifstream which is defined as
typedef basic_ifstream<wchar_t, char_traits<wchar_t> > wifstream;
cannot read unicode file correctly.
#include <fstream>
using namespace std;
void main () {
wifstream is ("c:\\test.txt");
wchar_t c;
while ((c = is.get ()) != WEOF) {
wprintf (L"%c", c);
}
}
output was:
..T.e.s.t.
When I tried short instead of wchar_t all went ok;
#include <fstream>
using namespace std;
void main () {
typedef basic_ifstream<short, char_traits<short> > ifs;
ifs is ("c:\\test.txt");
wchar_t c;
while ((c = is.get ()) != WEOF) {
wprintf (L"%c", c);
}
}
output was:
Test
Should wchar_t be defined as short or this is a bug
in standard C++ library shipped with VC++ 6.0?

Hello, i'm fairly new to c++ and programming in general, I'm looking for a decent alternative to microsoft visual c++ 2005 express edition, that is, any code that would work in that compiler would function the same.
I've already tried dev c++ but that uses mingu? So my code comes out with lots of errors when I compile, is there a free compiler that I can download that uses the same standard as express edition?
The reason that I am looking for an alternative is I'm experiencing some difficulty with running express edition in windows vista, I'm a college student studying programming so I need a compiler that works for my studies.

What kind of application did you use ? console ? Win32 ? Normally, this should work with DevC++. What are the compilation errors that you get ?

I am not an expert about Vista, but IMHO if you experience troubles with MS compiler, then probably you will experience more troubles with other ones.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

There's a service pack that fixes the vista issues, I believe. And you won't find a more standards compliant compiler than VC2005, not for free.

how to write a mfc code to search on start menu for installed software
-- modified at 6:31 Wednesday 16th May, 2007

Sorry, I can not answer you. But other times I have read about the people looked for installed software in Registry, not in StartMenu. I don't know if it is better, I only wanted to tell you about.
Greetings.

You can use the CString.Insert method and the += operator:
CString myString = "abc xyz";
myString.Insert(0, '[');
myString += "]";
See MSDN CString.Insert[^]
Hope that helps.

Man, you really have to learn to post to the correct forum[^]. It is not the first time you post managed code in the C++ forum and people have already told you to post in the managed forum.
Please, be carefull in the future.
