Write one Set function to set the data into the second dialog and then display this dialog.
For eg:
void SetData( PVOID pCustomData )
{
m_myData = (PMYDATA) pCustomData;
}
Or pass the data to the constructor of the second dialog...
Or use events to send the data to the second dialog and wrap the data inside the LPARAM or WPARAM parameters.

Use SendMessage Function that could be helpful for you.

You can modify your message.

Suppose you are creating these dialog in some class say a dialog class
CMainDlg
Class CMainDlg:Public CDialog
{
private:
Dlg1* pDlg1;
Dlg2* pDLg2;
......
}
Then in Class Dlg1 expose a function to Get the other dialog control's data and in class Dlg to set theat data
for eg
Class Dlg1:public CDilaog
{
public
CString GetDataFrmControl(); // supposing control's data type is of type CString
}
Class Dlg2:public CDilaog
{
public
void SetDataToControl( CString& Data ); // supposing control's data type is of type CString
}
///////////////////////////
CMainDLg::OnInitDialog
{
PDlg1 = new Dlg1;
pDlg2 = new Dlg2;
pDLg1->Create(..)
pDlg2->Create(..)
// pass the value from one dialog to another where ever needed
pDlg2->SetDataToControl( pDLg1->GetDataFrmControl())
}

What is the relationship between the two dialogs? Are they siblings? Does one "own" the other? Are they both modal?

The two dialog boxes are modal dialog boxes
|

///////if your main class is CMainDlg In another dialog you can use
<br />
#include "MainDlg.h"<br />
CMainDlg *m_Main=GetParent();<br />
m_Main->Yourfunction();<br />

Hey guys,
My name is Danny and I am working on a project using MFC based dialog and property pages. This question may sound really dumb, but I've added a key down handler for a property page I'm working on and for love or money I can't seem to get it to respond. I've thrown brake points everywhere and I can't get it to respond.
Are there any suggestions out there?
Thanks Guys.
Danny Nowlan

Map the WM_KEYDOWN message there you wil get which key is being pressed

Hi,
I'm using the OnNotify(WPARAM wParam, LPARAM lParam, LRESULT* pResult) method to find out when a user uses a scrollbar. Except I'm not sure what to be checking lParam against. I've casted lParam to be a NMHDR*, but when I check the value of pNMHDR->code, it's usually 0xFFFFFFF4.
Can anyone tell me what xxxxx should be in the following line?
BOOL CBaseFormView::OnNotify(WPARAM wParam, LPARAM lParam, LRESULT* pResult) <br />
{<br />
NMHDR* pNMHDR = (NMHDR*)lParam;<br />
<br />
if(pNMHDR->code == xxxxx) <br />
{<br />
}<br />
}
Or can someone tell me if I'm going about this the wrong way?
Thanks,
skyapie

You will get control at OnVScroll() OnHScroll() when the suer scrolls the scrol bar

That will work if the scrollbar is for the view, not for a list control or list box in the view...

If this scrollbar is of this view only then it will not send WM_NOTIFY message. Handle WM_VSCROLL message
skyapie wrote: BOOL CBaseFormView::OnNotify(WPARAM wParam, LPARAM lParam, LRESULT* pResult)
{
NMHDR* pNMHDR = (NMHDR*)lParam;
if(pNMHDR->code == xxxxx)
{
//Do stuff
}
}
This code will work , if you want to handle scrolling of child window of this view, lets say scrolling in listcontrol present as child of this view.

Hi !
I'm compiling my project with warnings at level 3. I didn't change any warning-behavior with #pragma.
The problem is that I get many warning C4100 (unreferenced formal parameter) because of included headers. How can I get rid of these warnings for which I cannot do anything anyway ?
(btw : I've seen somewhere that warning C4100 is level 4, but it occurs at level 3, that's strange ! any hint about this ?)
Thanks for your help !
Jerome

You just want to disable th ewarning right use #pragma
#pragma warning( disable: 4100 )
Is that not working ???

Which IDE are you using ? IF you use VC2005, there is an option in project properties that lets you disable specific warnings. Go in 'C/C++' -> 'Advanced' -> 'Disable specific warnings'. Put the warning number (without the 'C').
And don't know if this feature exists in VC6 (I already searched for it but couldn't find it). I don't know for VC2003 (never used it).
using pragma won't help I suppose because you probably don't want to modify these header files. And they probably don't include stdafx.h.

but he can always do this :
#pragma warning(disable:4100)
#include "the_header.h"
#pragma warning(default:4100)

Sure. But if he needs to include that file in several places, this can be a pain...
