How to handle results from a PropertySheet? - winapi

Question

I find different examples in the Internet of how to program a PropertySheet in WinAPI, but they are not complete.
The code I am using is shown below. I have a PropertySheet with 3 Tabs, each one with a Dialog.
The different Dialogs are called, when I click the Tabs, so far it is working.
However, when I leave the PropertySheet pressing OK button, how do I get the contents in the Textboxes etc. of each Dialog?
Normally I used to do that in the DialogProc when WM_COMMAND/IDOK was received using:
GetDlgItemText( hDlg,IDC_TEXTBOX1, buf, 100);
But in the PropertySheet there is only one OK Button for all dialogs, no WM_COMMAND/IDOK is received in the DialogProc.
What shall I do?
Resource_file:
IDD_DIALOG_1 DIALOGEX 0, 0, 385, 186
STYLE DS_SETFONT | DS_MODALFRAME | WS_POPUP | WS_CAPTION | WS_SYSMENU
BEGIN
LTEXT "param",IDC_STATIC,6,23,39,10
EDITTEXT IDC_TEXTBOX1,48,20,237,15
END
C Source:
LRESULT CALLBACK
Dialog1(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam)
{
char buf[500];
char* ptr;
int p; // =lParam, rin of edited person
int f;
switch (message)
{
case WM_INITDIALOG:
{
SetDlgItemText(hDlg, IDC_TEXTBOX1, "something");
return 0;
}
case WM_COMMAND:
{
switch (LOWORD(wParam))
{
case IDOK: // never reached (OK Button belongs to the PropertySheet!)
}
}
}
return FALSE;
} /* Dialog1 */
INT_PTR DoPropertySheet(HWND hwndOwner, LPARAM p)
{
PROPSHEETPAGE psp[3];
PROPSHEETHEADER psh;
memset(psp,0,sizeof(psp));
for(int i=0;i<3; i++)
{
psp[i].dwSize = sizeof(PROPSHEETPAGE);
psp[i].dwFlags = PSP_USETITLE;
psp[i].hInstance = hInstance;
psp[i].lParam = p;
}
psp[0].pszTemplate = MAKEINTRESOURCE(IDD_DIALOG_1);
psp[0].pfnDlgProc = (DLGPROC)Dialog1;
psp[1].pszTemplate = MAKEINTRESOURCE(IDD_DIALOG_2);
psp[1].pfnDlgProc = (DLGPROC)Dialog2;
psp[2].pszTemplate = MAKEINTRESOURCE(IDD_DIALOG_3);
psp[2].pfnDlgProc = (DLGPROC)Dialog3;
psh.dwSize = sizeof(PROPSHEETHEADER);
psh.dwFlags = PSH_PROPSHEETPAGE | PSH_NOAPPLYNOW;
psh.hwndParent = hwndOwner;
psh.hInstance = hInstance;
psh.pszIcon = 0;
psh.nPages = sizeof(psp) / sizeof(PROPSHEETPAGE);
psh.nStartPage = 0;
psh.ppsp = (LPCPROPSHEETPAGE) &psp;
psh.pfnCallback = NULL;
if (PropertySheet(&psh)) // 0:cancel, otherwise:1
{
//get contens of propertySheet here?? how??
}
return 0;
}

when user press OK or Apply all your pages got PSN_APPLY notification code. so you need look for WM_NOTIFY with PSN_APPLY code
when user press cancel you got PSN_RESET notification
INT_PTR CALLBACK PPDlgProc(HWND hwnd, UINT umsg, WPARAM wParam, LPARAM lParam)
{
union {
LPARAM lp;
NMHDR* hdr;
PSHNOTIFY* psn;
};
switch (umsg)
{
case WM_NOTIFY:
lp = lParam;
switch (hdr->code)
{
case PSN_APPLY:
DbgPrint("apply");
break;
case PSN_RESET:
DbgPrint("cancel\n");
break;
}
break;
}
return 0;
}
