You can use SendMessage() and PostMessage() to send messages from one application to the other. Keep in mind, however, that it is not a trivial task of finding a window given a process id (i.e., that which is returned by CreateProcess()).

You should handle WM_SYSCOMMAND
with wParam == SC_CLOSE

Can you disable/hide or delete the [x] button?

good luck.

Actualy this functionality is there if you use CHtmlView as you View class and CHtmlDoc as your doc class, but then u cannot insert activeX control in it... cause for making a container u need to derive from ColeDocument. Can anyone tell me how to do this.

I think the Problm in Query to the key

here

CRegKey reg;
CString str = "cam";
BOOL bRetVal;
CString strTmp = "Software\\NDT\\Fovea";
bRetVal = reg.Open (HKEY_LOCAL_MACHINE ,(LPCTSTR)strTmp ) ;

if (bRetVal==ERROR_SUCCESS)
{
CString key = "Password";
char getValue[256] ;

DWORD d;

bRetVal=reg.QueryValue ( getValue , (LPCTSTR)key , &d);

if (bRetVal==ERROR_SUCCESS)
{
AfxMessageBox(" Working fine");
CString check = (CString)getValue ;
AfxMessageBox( "Value is ....||"+ check);
if (str.Compare (check) == 0)
{
AfxMessageBox( "Same");
reg.Close ();
}
else
{
AfxMessageBox( "Not same");
reg.Close ();
}

}

else

AfxMessageBox(" Query Failed");
}
else
{
AfxMessageBox( "Cannot Open");
reg.Close ();
}

It is messaging Query Failed..

remeber one thing,QuerryValue Third Parameter containing values goes Both IN and Out so if you want to run your Program properly change DWORD d; to DWORD d=255;//one space for null character

->Basically when the function is Called, the DWORD value Must contain the buffer size of string (which is going in as Second parameter for fetching required Value).

->when function return it contain the value for Total data in second Parameter Return .

determine if contents of dialog are changed

hi,
how do i determine if the contents of the dialog are changed from the initial values. i have edit boxes, check boxes, etc. after initialization of the dialog with the default values, how do i determine if the contents of the dialog are changed?

Re: determine if contents of dialog are changed

Johan Rosengren14-Jul-04 20:38

For editboxes you call GetModify (or send EM_GETMODIFY if you are not using MFC). Otherwise, you'll have to do it manually.

Re: determine if contents of dialog are changed

V.14-Jul-04 21:00

Most controls have a sort of OnChange Handler or OnClick...
Right click the control and choose "add event handler".
If something changes in your edit box you can check it against the original value.

good luck.

Change MFC Class Wizard behaviour

14-Jul-04 16:12

I have 2 things regarding MFC Class Wizard behaviour I wish to modify:
1. When using MFC Class Wizard's New Class Dialog, the content of Base Class ComboBox are all the standard MFC class. Is there anyway to add new classes into this ComboBox items.
2. When adding member variable of a class for certain dialog control, is it possible to override the default one, for example, instead of variable type of CButton, the system can allow us to select CRoundButton.

Thanks for any help provided.

AFAIK No.

Sure, use the Text Wizard to change CButton to CRoundButton.

Thank you for your information. But I don't understand what is a Text Wizard.
Do you mean I update the data in the header file directly? I know this can be done but I am looking for possibility to do it more efficiently.

Where can I get Informations or articles about several registry commands? For Example HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System\NoDispCPL.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
