thanks for the reply. One question what headers are needed for the includes? you didn't turn the <> function on in your post so it wiped out the includes.
Thanks again,

Can any body tell me how to completely automate the build of a vc++ project from command line.I want to export makefiles automatically and build it.It's urgent.

Can nobody answer me?Is it because it's a dumb question?I'm a fresher.I would be grate ful to you,if anybody helps me.

This article[^] in the MSDN describes the command line switches for VS.NET 2002/2003. You can use these to build projects or whole solutions from the command line or in a batch file.
If you are still using Visual C++ 6.0, there are similar command line options for it; you'll need to check the help text.

Hi,
I am new in MFC window based application.
I have created a SDI project(based on document view architecture) using MFC wizard. I want to remove menu bar and title bar completely. How can I do that?
Advance thanks for support.

In the dialog design view, right click on the dialog and select properties, there are checkbox where you can remove the titlebar.

Hello,
That chap is asking about SDI Application and not Dialog based application...dont confuse him....

Sorry for the wrong answer before here what you need to do, in the mainframe window, add the virtual funtion for PreCreateWindow(..) if it is already there then in that method the paramter CREATESTRUCT has a member variable called dwExStyle. if you modify the style here you will get the corresponding style of your window.

{
cs.style = WS_DLGFRAME | ~WS_BORDER | WS_OVERLAPPED ;
cs.hMenu = NULL;
// Create a window without min/max buttons or sizable border
// cs.style = WS_OVERLAPPED ;
return CFrameWnd::PreCreateWindow(cs);
}

I am using MFC and am having a bit of a problem with accessing a control in a generic class I created. I am using FormView as it has both dialog and menus in it. This may be a simple problem, but I am still new to MFC and I can't seem to figure it out.
I created a formview class with an edit box, then subclassed the edit box so I could trap the enter key. Now, I need to access a list box on the form from a generic class that I created. I know I need to create a pointer to the formview class, but I am unsure as to how to do this or how to access the list box control variable. I tried using getparent() as in:
(CFormView*)GetParentOwner()->GetDlgItemText(IDD_ITEMSLIST, model);
and could not access the control. I get errors saying the control is an undeclared variable. Any help or a web site that explains this would be greatly appreciated.

MFC creates automatic class hiearchies, and has a set of functions that allow you to traverse and manipuate the hiearchy.
Consider the following example:
1. An application object is created
2. The application object creates and initializes it's main window (usually a frame window), and saves this into m_pMainWnd pointer on the CWinApp-class
3. The frame window, if it is an SDI frame, first creates a set of possible bars (toolbar, statusbar, menubar, rebar etc). Then it creates the view context, and places itself as a parent of the view.
This having said, you can find the form view class object by asking the frame window to enumerate through it's child windows. Alternatively, you can use GetDlgCtrl with the ID of the child window (by default, AFX_IDW_PANE_FIRST, unless you have given it a different ID while creating it). Here is what MSDN says about the function call:
You can use the GetDlgItem function with any parent-child window pair, not just with dialog boxes. As long as the hDlg parameter specifies a parent window and the child window has a unique identifier (as specified by the hMenu parameter in the CreateWindow or CreateWindowEx function that created the child window), GetDlgItem returns a valid handle to the child window
As you can see, the MFC implementation of this function always returns a CWnd* to the requested object. Now, when you ask for the view class pointer, you can cast it down from CWnd* to CFormView*. Again, by using this pointer, you can use GetDlgCtrl to request for a pointer into the CListCtrl object.
The reason why your code call fails is that although the form view is a child of the frame window, the list box control is NOT. It is the child of the form view. You need to use a pointer to the form view class instance if you wish to request for the listbox.

I don't suppose you could show me how to do this. I tried using CFormView* pDiag = (CFormView*)GetParentView()->GetDlgItem(IDC_DATA),
but it still does not give me access to my ListBox and I cannot insert data into it since I cannot access the control variable on my viewform. I know I am being a bit dense here, but this is still new to me. If I was dealing with just a console based Application I probably would not have as much trouble, but I don't really know how to do this in MFC and the explanations I have read so far have not really shed any light on how I need to do this other than I now know I need to create a pointer which is what I am having trouble with at the moment.

Hello !
First I need to ask you the simplest of all questions: what do you use to switch between the views ? If it is a button or anything that accepts messages, write a handler for it and create/show a modeless dialog box when a click on this item designates that the "view with the dialog" should be shown. When a click on the item occurs that says "show the other view", you command the modeless dialog to either hide itself or destroy it.
The message order is dependant on the phase of your window object. Usually, different events on the Windows OS can be grouped by the messages sent. The only reasonable way to track the message order on a window is to use Microsoft Spy++, or a similar message hooking program.

Can anybody tell me how can i call the member function of one class through the other class using Send/Post Message?
Vidya
|
|
|
|

2 ways that I am aware of.
1 make the member function static and call it as CMYCLASS::Memberfunction(...) on the message handler for the posted message.
2. In the message paramneter cast the this pointer ta a long and pass it with the message. Cast it back to the class in the message handler. I think this breaks some of the concepts of proper OO

Hello,
In stdafx.h put the following stuff
#define WM_TALELE_CLICK 3000
..
..
..
---------------------------------------------------------------------------
then in XYZ.CPP put following stuff
.
GetParent()->PostMessage(WM_TALELE_CLICK,m_id,0); //e.g m_id is paramater to be passed
.
.
.
---------------------------------------------------------------------------
Implementation.h
void OnTaleleBtnClick(WPARAM wp, LPARAM lp);
---------------------------------------------------------------------------
then in Implementation.cpp
BEGIN_MESSAGE_MAP(CIMP, CXyz)
ON_MESSAGE(WM_STATICBTN_CLICK, OnTaleleBtnClick)
END_MESSAGE_MAP()
void CIMPL::OnTaleleBtnClick(WPARAM wp, LPARAM lp) //wp ==m_nID
{
switch(wp)
{
case NEWS_BTN:
::MessageBox(0,"Newsx btn","News",0); break;
case ALERT_BTN:
::MessageBox(0,"Alert btn","News",0); break;
default : break;
}
}
---------------------------------------------------------------------------
you are done..... I had actually implemented...and executed successfully, dear vidya

Technically, you can't use SendMessage() or PostMessage() to call functions. The message handler can, however.
#define PM_STARTPROC 123
BEGIN_MESSAGE_MAP(CMyDialog, CDialog)
ON_MESSAGE(PM_STARTPROC, OnStart)
END_MESSAGE_MAP()
BOOL CMyDialog::OnInitDialog()
{
CDialog::OnInitDialog();
PostMessage(PM_STARTPROC);
return TRUE;
}
LRESULT CMyDialog::OnStart( WPARAM wParam, LPARAM lParam )
{
return (0);
}

Hey
I have an icon. I would like to insert the icon into a toolbar.How to do?
Thanks
JP

Insert an icon means to insert a new toolbar button if so use TB_INSERTBUTTON message to do it.

Use...
TB_INSERTBUTTON
AddButton(...);
which has following paramater
HRESULT AddButtons(
int nButtons, // number of buttons
LPMMCBUTTON lpButtons // pointer to an MMCBUTTON structure
);
LPMMCBUTTON .....
typedef struct _MMCBUTTON
{
int nBitmap ;
int idCommand;
BYTE fsState;
BYTE fsType;
LPOLESTR lpButtonText;
LPOLESTR lpTooltipText;
} MMCBUTTON;
typedef MMCBUTTON* LPMMCBUTTON;

The address of func m_PFoo is 0x0211D4B0, it's all right.
What 's the problem with my program and how to fix it ?
Thank you very much !

I don't think you need that pointer to call the function since it's already a pointer, so 326 becomes:
retval = (m_PFoo)(infc, infv, exfc, exfv, m_lpDCL, m_lpUserFunctions);
