it says in HRESULT "CoInitialize has not been called."
|

|

There ya go 
in order to call CoCreateInstance, you need to load the COM libraries. this is done by
CoInitialize method (check out MSDN for more information)
don't forget to call CoUninitialize when done using the COM libraries
good luck

Go to project settings>link and then search for the Object/Library Modules
Add the following entries to the end of the text box in the line
Opengl32.lib glaux.lib glu32.lib
Now in the file whereyou are using open gl functions,include the two files given underneath
#include "gl/gl.h" <br />
#include "gl/glu.h"

Hi,
I have created a List Control. I have to add the text by default by which the user can modify the text as required.
List control ID :- IDC_EXCLUDE_FILTERS_LIST
Type :- CListCtrl
Member :- m_EXCLUDE_FILTERS_LIST
I have to add the folowing text by default when the Dialog window loads.
*.exp *.ilk *.res *.trg *.tlh *.idb
*.pdb *.pch *.opt *.lib "*\Deleted
Items\*" *.cab *.mov *.mp3 *.swf
*.psp *.bmp *.chi *.chm *.com *.dll
*.exe *.gif *.hlp *.ivi *.ivt *.ix
*.jpeg *.jpg *.msi *.nl.mpeg *.mpg
*.ram *.rm
Can anyone please tell me how to add the default text to the list box & also user can edit the text and also remove the text..
I dnt know properly that i have to Edit Box or List box. but the text should be
multiple lines where the user can edit the text.
Regards,
Parichay.

I've no idea what you are trying to say here.

What do you mean "by default?" What control do you want this text added to? If it's a list control, please explain in more detail as that control can be displayed in many different formats (e.g., report, list, icon).

Now you are using a listbox?

Do you need an edit control for this?

Hey folks:
I've got a nice C++ STL string and I need to turn it into a TCHAR.... (and I can't use MFC)
I've tried:
typedef std::basic_string< TCHAR > tstring;
and it doesn't work (or it does, and I don't know how to use it) ... basically how do I convert these types?
Thanks!

typedef std::basic_string< TCHAR > tstring;
is the correct syntax for changing a STL string to TCHAR
Now when you want to change the string to tstring you can use
tstring("ABCXYZ"); that's all
I hope this works fine at your end but there may be some other problem in the way you are using this code.Please specify how you are using the code.

So I have the following header, but basically, I have a STL string that I want to convert to tchar, to call Win32 APIs... (that require the use of LPTCSTRs) when I try your suggestion:
tstring blah = tstring("ABCXYZ");
I get the error:
error C2440: '<function-style-cast>' : cannot convert from 'const char [7]' to 'tstring'
Could you provide a more elaborate example? Thanks!
#include <windows.h>
#include <stdio.h>
#define NULL 0
#include "LogFiles.h"
#include "TestPrint.h"
#include <string>
#include <iostream>
#include <conio.h>
using namespace std;
typedef std::basic_string< TCHAR > tstring;
