Indeed 
However, unless somewhere there is a corresponding delete for non-null pointers, I suspect you might have at the very least some diagnostics about leaks when running under the debugger.

no this is was the only delete for that object in the dtor. Yes there was a memory leak in this case and other places.
I just placed it in my sig to show that how stupid anyone can get to write that kinda of code.
But then i removed it coz i thought it was not rite to make a joke of others programming pratice.

Hi, I've an ATL activeX control that is a dialog with some windows. When it's hosted in IE there are resizing problems (it has resizing border) when IE isn't maximized. The dialog will not draw outside its original size, even though the border seems to drag out to a much larger size (the controls and dialog size, but are clipped to the original width and height). This doesn't happen when IE is maximized, as the dialog and controls are drawn to new sizes/positions.
I've no idea of the cause, is it a bug in IE or just a special case I need to account for in the code?
Thanks in advance.
Brian.

in a BHO, if the user clicks on any word how can i know which word user clicked on
there is a function elementFromPoint but that will give the whole Element i want the specific text
how does IE know that the stuff under the mouse is Text cause the mouse pointer changes to a carat when the mouse moves over text on a HTML page
C makes it easy to shoot yourself in the foot; C++ makes it harder, but when you do, it blows away your whole leg

In OnClick Event Write this :
CComPtr<IHTMLTxtRange> spHTMLTxtRange;
m_pHTMLBody->createTextRange(&spHTMLTxtRange);
spHTMLTxtRange->collapse(VARIANT_TRUE);
long x,y;
pEvent->get_clientX(&x);
pEvent->get_clientY(&y);
spHTMLTxtRange->moveToPoint(x,y);
spHTMLTxtRange->expand(CComBSTR("word"),&vtBool);
spHTMLTxtRange->get_text(&bstrText);
//bstrText now contains the Word which user clicked

i have an full control ImageControl.
i have a composite control imageDisplay.
i want to put imagecontrol into imagedisplay. that's fine.
but when i want to invoke a method in imageControl, i can't. not even to compile. i am using code i found in txts and websites:
CComPtr<iimagecontrol> pImg;
GetDlgControl(IDC_IMAGECONTROL, IID_IImageControl, reinterpret_cast<void**> (&pImg));
error: IImageControl unknown identifier.
must i import something? when i inserted the ImageControl, a h.file and cpp.file is added to the project. but neither defines the interface of imagecontrol.
must both source codes be in the same project to work?
help....

Hello,
I’m looking for a way to display the SysTreeView32 control in a WTL application. Is there an easy way to do this or is there a custom WTL control that can be used? Should I resign to my fate and implementing my own?
If I have to implement my own, what are your recommendations? IShellFolder interface?
Thanks in advance,
-mass

There is the excellent http://www.codeproject.com/shell/explorer.asp article by leon Finker (WTL), I think it just lack notification. Also an ATL Tree activeX http://www.codeproject.com/atl/shellfoldertree.asp by Nick Hodapp.
These are the 2 I prefer and both WTL compatible.

I'm just getting into atl but do not think I have all the header files, notably :
atltypes.h
is missing.
I have spent they day downloading various microsoft updates and SDKs but still have not found this file.
any hints?

I think this is a VC.NET only file. If you're using ATL3.0/3.1 from VC6, you won't have this file, and as far as I know, the only legal way to get it is to buy and install a copy of VC.NET

hello,
how to overload this operator []
here is the function & type
string& CPCMGroupComputers::operator[](int idx)
{
return m_lstrComputers[idx];
}
list<string> m_lstrComputers;
|
|
|
|
|
|
hello,
but it is giving error.
please check it again.
string& CPCMGroupComputers::operator[](int idx)
{
return m_lstrComputers[idx];
}
here is the type .....
list<string> m_lstrComputers;
please check it
regards
skp

Im assuming that m_lstrComputers is a std::list < std::string >
In that case, your error is that std::list< T > does not have an operator[], which is logical since it does not support random access iterators. You will have to walk your way to idx either from .begin() or .end().
#include < string >
#include < iostream >
#include < list >
using namespace std;
class c
{
list< string > l_;
public:
c()
{
l_.push_back("test");
l_.push_back("me");
}
string operator [] (unsigned int i)
{
list< string >::iterator it = l_.begin();
while (i-- != 0)
it++;
return *it;
}
};
int main()
{
c c;
cout << c[0] << endl;
return 0;
}

Of course, this is true. However, instead of writing his own loop for that, he can simply use advance function template. Something like:
string operator [] (unsigned int i)
{
list<string>::iterator it = l_.begin();
advance(it, i);
return *it;
}

Even better!
I havent seen that function template before (Im only halfway through my copy of Josuttis book). Thanks for the tip! ![Beer | [beer]](https://www.codeproject.com/script/Forums/Images/beer.gif)

Hii Everybody,
I have written a ATL COM Component and I am calling through ASP.NET Web Application. But after after logout and setting object of component to null, It is not releasing component at all. I have to stop process aspnet_wp.exe for recompilation of component.
Any suggestion by you all experts that how can I release component after logout of web Application?
Please help me...

Marshal.ReleaseComObject
To quote MSDN: "This method is used to explicitly control the lifetime of a COM object used from managed code. You should use this method to free the underlying COM object that holds references to resources in a timely manner or when objects must be freed in a specific order."

It has nothing to do with CTreeViewCtrl. Look for bugs in your program.

Hi list,
I need to compile the following code with gcc:
//test.cpp
#include <iostream>
int main()
{
std::cout << "Hello World";
return 0;
}
But trying "gcc test.cpp" fails miserably, because it cannot find some symbols:
ld: Undefined symbols:
std::ios_base::Init::Init[in-charge]()
std::ios_base::Init::~Init [in-charge]()
std::cout
std::basic_ostream<char, std::char_traits<char> >& std::operator<< <std::char_traits<char> >(std::basic_ostream<char, std::char_traits<char> >&, char const*)
Can anybody please help me to find what is really missing?
TIA
