All MFC windows (including CDialog objects) derive from CWnd. Just cast it to CWnd in the create function

You are using the wrong control. Use a CListView control rather.

Okay Thanks,
Could u please tell me how to achieve the above said things using the
CListView control.

By [2],I mean to make the listview control to the size of the dialog,while displaying & not to the size of the view.

By ListView control,did u mean list control co's,while in the control tool box,I see only list contol & listbox control

It is CListCtrl.
You can use these functions of the class
eg:
To add columns
m_ListCtrl.InsertColumn(1,"1st Column");

To add data to the control
m_ListCtrl.InsertItem(0,"Data");
m_ListCtrl.SetItemText(0,1,"Value");

How will I connect my view class which is derived from Cview to the control object,Co's I want to test the list control

Did as follows:

On the,"OnCreate" function of my view class,I did as follows

m_lstctrl.Create(WS_CHILD|WS_VISIBLE|LBS_STANDARD|WS_HSCROLL,
CRect(10,10,200,200),this, IDC_TEST);
m_lstctrl.InsertColumn(1,"1st Column");

But I dont see any columns ,apart from the listctrl box boundary...

You can adjust the CRect(..) in the Create function.
Or add WS_SIZEBOX style,then you can resize the control at runtime.

ok, to add columns to the list control, make sure that you create the control with the LVS_REPORT style.

then call CListCtrl::InsertColumn() to add a column and then CListCtrl::InsertItem() to add items. I saw a post that already indicated this.

Now to the problem of sizing the control to the size of your dialog:

In the dialog class, handle the WM_SIZE message, call GetClientRect() to get the current client rectangle of the dialog and then just call CListCtrl::MoveWindow() to size the list control to the size of the dialog.

HOpefully that explains it.

Unless you absolutely have to, it's easier to create the control at design-time rather than at run-time. As to your question about the Create() method, the third parameter would be the this pointer. For example:

BOOL CMyDialog::OnInitDialog()
{
    m_listbox.Create(..., this, IDC_LISTBOX1);
    return TRUE;
}

You can do this with a listbox (by using tab stops), but as already mentioned, it's much easier with a list control.

Debug with .NET 2003

Hi !

I just started developping with Visual .Net in C++ (unmanaged).

I'm facing a strange behavior in the debugger : if I go step by step in my code (F10), the debugger just step over many lines of code, and the variables viewer let me see that the object I'm debugging is in a very strange state, many member variables being uninitialised (which was supposed to be done in my constructor).

Did you already had such a strange behavior ? Is it possible to solve it ?

Thanks !
Jerome

Is this an existing piece of code converted from VC6 to VC7 or is it new code?

If existing code, try a complete clean of the DEBUG directory and compile again.

How to reposition Modeless Dialog box on resizing application window

Arun AC27-Jun-04 23:22

27-Jun-04 23:22

Hai all,

I use a modeless dialog box in my application.

when I resize the application window, I can not change the position of the modeless dialog box, correspondingly.

How can i prevent it?
Also, the window for the modeless dialog in the task bar is also seen.

Simply, I am trying to make the Modeless Dialog box to be a part of my application window.

Please help me,

With Thanks and Rgds,
Arun

If my understanding of your problem is correct, you are trying to use a modeless dialog to look as if its a "pane" within your application. If this is correct, read on:

1. Make the dialog a CHILD dialog
2. In the parent window, handle the WM_SIZE message and then merely resize the child dialog.

For example (a WTL eg):

<br />
void OnSize(UINT uiCode, CSize sz)<br />
{<br />
  CRect rect;<br />
<br />
  GetClientRect(&rect);<br />
  if ( ::IsWindow(m_MyChildDialog.m_hWnd) )<br />
  {<br />
    // do some manipulation on the rect if needed...<br />
    rect.DeflateRect(10,10,10,10); // here I'm just decreasing the overall size of the rect<br />
    m_MyChildDialog.MoveWindow(&rect);<br />
  }<br />
}<br />

That should be all you need to do.
Let me know if I've missed your question completely.

Cheers,
Peter

How To read an exe application from VC++6.0

karhea27-Jun-04 22:39

27-Jun-04 22:39

Hi,

I know how to run a VB exe file from VC++6.0 but have been trying to read the contents of the exe from VC++. Like if the VB application has ODBC coding in it then I would like to read the kind of API calls that it is making through VC++ application. Is it possible to do like that?. Is it possible to intercept an exe program and know what all objects it is accessing? If yes then how do I do that?

Thanks in advance.

I think what you are looking for is an "API hook." There are several examples here at CP. You can also Google for more.

Another way would be to parse the EXE itself by examining the .idata section (i.e., import table) of the file. It lists the functions called in other DLLs.
