The difference is that AppWizard generates a different stdafx.h for the two
project types. For a Win32 app, stdafx.h includes windows.h , but for a Win32 console app stdafx.h does not include windows.h.
Somethings seem HARD to do, until we know how to do them.

Yes if you want to Windows based GUI apps. Otherwise you'll get errors

The system creates a new console when it starts a console process, a character-mode process whose entry point is the main function. For example, the system creates a new console when it starts the command processor. When the command processor starts a new console process, the user can specify whether the system creates a new console for the new process or whether it inherits the command processor's console.
A process can create a console by using one of the following methods:
-A GUI or console process can use the CreateProcess function with CREATE_NEW_CONSOLE to create a console process with a new console. (By default, a console process inherits its parent's console, and there is no guarantee that input is received by the process for which it was intended.)
-A graphical user interface (GUI) or console process that is not currently attached to a console can use the AllocConsole function to create a new console. (GUI processes are not attached to a console when they are created. Console processes are not attached to a console if they are created using CreateProcess with DETACHED_PROCESS.)
Currently I am working as software engineer at Network System Technologies Pvt. Ltd (NeST). Most of my project are in C++. Most interesting are is GUI programming.

There are two major differences between Win32 console and Win 32 application.
1.If it is win32 console application, mainCRTStartup() gets called first,which inturn calls main() method.
If it is win32 application,then WinMainCRTStartup() gets called as Entry point ,which in turn calls WinMain
2.Under compiler settings, the /subsystem flag is set to /subsystem:windows for Win32 application, /subsystem:console for Win32 console application.

Simple.
Win32 app creates a MSWindows type interface and Win32 Console Application creates a MSDOS (Similar to command prompt).

The former creates a Win32 application while the latter creates a console application. I'm assuming you know the difference betweeen a Win32 application and a console application, yes?

I am having an issue after I use this function.
If I have a sink for Outlook _Application events, I get a 0xF007 event ( Close ) when Outlook closes, which is great... but
If I get a _ContactItem and Display() it, when that item gets closed the ApplicationEvents handler gets a 0xF007 event to suggest that Outlook is closing. Any ideas why this might be ?

{ CDialog::OnInitDialog();
m_ctrlSNAME.SetWindowText(sfile);
m_ctrlSLOCATION.SetWindowText(slocation);
HANDLE hr;
hr = CreateThread(NULL,0,(unsigned long (__stdcall *)(void *))WorkerThreadProc,this,0,0);
return TRUE;
}

What you are doing here is simply declaring a new instance of the CStatusDlg class (CDialog classes are still classes even if they are GUI 'components' ). So, you are not accessing the data from the 'dialog' that is on the screen. I won't suggest you to pass the dialog through the thread data because it's bad to share MFC classes across thread.
What you can do is send the required data only to your thread. But I think your design is not correct: if you start your thread in OnInitDialog, the user has not entered data on your dialog so the data is not valid. Why not start your thread later, when the user has entered data and requested your thread to be started (in general, if the thread is required for processing, the user start the processing right ?)

Hi Cédric Moonen,
Thank you u very much for the reply.
I have 3 dialog window, in which I am accepting data from the user in the 2nd dialog window and when the user press on start process ,it should display 3rd window and start processing immediately after dialog load so in the 3rd dialog window user has option or no need to enter any data.
Since I have to 2 process Dialog load and also process I have used the Thread so that dialog loads and also processing also takes place ..
For processing of data I need to access those values can u please tell me is there any way to do that …
I want both the values in the thread function in the loc field can u help me with this…

UINT WorkerThreadProc(LPVOID Param)
You can access to the parameters through Param variable, if you are not still using that:
interpret it as a pointer to the dialog that contains the variable members, and then reach the values .
If you are using Param in another way you could create a struct where you can store every information that needs to be passed to the thread.
But, be carefull : if you create a local (like in OnInitistance)instance of the structure, that will be destroyed when the function ends, i.e. before that the thread ends,....so goodby to the paramenters
You can solve this problem using a memeber variable into the first dialog or with dynamical memory allocation (but others problems cames to free the memory ).
hope be clear

Hi _Russell_,
Thanks for the wondeful reply and thanks a lot for giveing lot of information.
I am very much new to VC++ and threds ,i just learned threads by some sample notes i am really very new to it ...

{
CDialog::OnInitDialog();
m_ctrlSNAME.SetWindowText(sfile);
m_ctrlSLOCATION.SetWindowText(slocation);
CString str;

hr = CreateThread(NULL,0,(unsigned long (__stdcall *)(void *))WorkerThreadProc,this,0,0);
return TRUE;
}
--------------------------------------------------------------

{
CStatusDlg status;
//CString loc = status.slocation + status.sfile;
char * d =(char *) (LPCTSTR) loc;
return true;

You'll need to use AfxBeginThread() here.
vinaycool wrote: CStatusDlg status;
status will need to be a pointer to a CStatusDlg. You need to cast Param to this.

Hi,
I have a customised menu class derieved from CMenu.
I have overridden the DrawItem n MeasureItem functions.
The problem is with having title for child menu.
I'm addin childmenu through
AppendMenu(MF_POPUP | MF_GRAYED | MF_OWNERDRAW , nID, (LPCTSTR)color))
now if I want to have a title for submenu eg:colors in the below case
shapes
colors->green
red
sizes
how can that be done.
Even if I use InsertMenu() then again there is a problem,we cannot have OwnerDraw n
MF_STRING together.
Is there any solution for this?
Thanks.

Hi,
You can use GetFileAttributesEx -> if dwFileAttributes from WIN32_FILE_ATTRIBUTE_DATA struct will have FILE_ATTRIBUTE_DIRECTORY - so it's directory

hi,
try CPath::IsDirectory(). But it is an ATL class. You have to include atlpath.h
Adios,

No, there is no difference, NULL is defined as 0.
It's just that using NULL for a pointer is more convenient (to make the difference with the 0 value).
