How to send a message to a dialog - C / C++ / MFC Discussion Boards

1. Learn to be patient. You asked this earlier today.

2. Learn to use MSDN search engine.
Goto Microsoft's Developer Network[^] site, and in the "Search MSDN for" box, type in

Create access database c++

and press 'Go'. This will bring up at least one article explaining how to do this using DAO. If you want to use OLE DB instead, try

JET database c++ "OLE DB"

as your query.

MS are recommending OLE DB or ADO over JET/DAO and ODBC for "portability" reasons (JET won't be supported on Win64).

You could also try and get hold of either

Database Programming with Visual C++ 6 in 21 days (Sams)
or
Visual C++ 6 Database Programming Tutorial by Wendy Sarrett, although my copy is a Wrox Press book, and they don't do it any more. Amazon might have used ones though...

I can Tell you the way to get every User account present in the computer but other details i can't.

actually Win9x treat Every user same, ie ADMIN as it has full control over computer.

this is way you can Find all theuser present in you computer ,but remember this is hack.

you have to enumerate the Key Under HKEY_USERS section ,is Key name is equivalent to Username.

TTN_NEEDTEXT Not Calling

Hi all,
I'm using tooltip in an MFC ActiveX Control Project. I have added Handler for TTN_NEEDTEXT Notification Message. But this Notification is not calling. I tried in an SDI Application. It works.. Could anyone tell the solution

BEGIN_MESSAGE_MAP(CEx1Ctrl, COleControl)
//{{AFX_MSG_MAP(CEx1Ctrl)
ON_WM_MOUSEMOVE()
ON_WM_PAINT()
ON_WM_SIZE()
ON_WM_CREATE()
//}}AFX_MSG_MAP
ON_NOTIFY_EX(TTN_NEEDTEXT, 0, OnToolTipNeedText)

ON_OLEVERB(AFX_IDS_VERB_PROPERTIES, OnProperties)
END_MESSAGE_MAP()

regards

Rajesh

Does EnableToolTips() need to be called? Is their a group box surrounding the control?

Rajesh_Parameswaran wrote:
ON_NOTIFY_EX(TTN_NEEDTEXT, 0, OnToolTipNeedText)

Try this instead:

ON_NOTIFY_EX_RANGE(TTN_NEEDTEXTW, 0, 0xFFFF, OnToolTipNeedText)
ON_NOTIFY_EX_RANGE(TTN_NEEDTEXTA, 0, 0xFFFF, OnToolTipNeedText)

How to send a message to a dialog

Nest22-Nov-04 0:15

Nest

22-Nov-04 0:15

I have a view from wh Eek! | :eek:

ere I call an Object A property dialog (modal). In that Dailog I call an Object B property dialog (non modal). It may happen that the Object A is destroyed in the Object B property dialog. So it looks logical to close the Object A property dialog automatically by sending it a message to close itself. OK, I know how to write and handle messages in general but i don't know how to send a message to the Object A property dialog.

Should i store a pointer to this dialog and then call a SendMessage? Looks absurd...
SendMessageToDescendants() called for AfxGetMainWnd() doesn't work...

Any explanation would be appreciated.

Hi,
you can define a public function in the ObjectA property Dialog and in the second dialog's close function, u just create a member of the first one and invoke the public function of ObjectA dialog box, which inturn calls the OnOK() function.

ObjectA.cpp
---------
void CADlg::Destroy()
{
OnOK();
}

ObjectB.cpp
-----------
void CBDlg::OnButton1()
{
// TODO: Add your control notification handler code here
OnOK();
CADlg *pWnd = (CADlg*)GetParent();
pWnd->Destroy();

}
or

can also use this way

void CBDlg::OnButton1()
{
// TODO: Add your control notification handler code here
OnOK();
CADlg *pWnd = (CADlg*)GetParent();
pWnd->EndDialog();

}

Regards,

Rajesh

It's not that easy - the dialog B is a modaless dialog and its parent is a MainFrame...

maybe this could help.....
use GetParent() function and retrieve the pointer to the main window,
then use the PostMessage(WM_CLOSE, 0, 0);

hope that helpz.....

Boy what a question, hundreds of articles have been written on this M$ spent great deal of time with iffy solutions. As for default buttons that is easy, Right Click on the Dialog in the resource view, Properties, Language.

Make sure your compiler has the targeted lang pack installed from M$.

How to resolve Regsvr32 Error?

21-Nov-04 22:19

I am having trouble in registering a dll module which is an add-in for Visual Studio .NET 2003:

DLLRegisterServer in cyclocomplexviewernet.dll failed.
Return code was: 0x80070002.

Using the Error Lookup tool this means:
The system cannot find the file specified.

My question is how do I find out how to find which file the regsvr32 program is looking for?

Try to use Denpends in Visual Studio Tools to investigate which runtime dll is needed.

Create one function called Writelog(), pass the error code to this function
and write to some file. Now check what is the root of problem !

Try to get error code using GetLastError()

nways have you written RegisterServer() function in your code of dll ?

Since FranzKlein already have the error code :"0x80070002", wots the point in using GetLastError() again ?

No, compilation runs fine. It occurs when I use Regsvr32 to register the specified dll with the registry.

Try entering the fully qualifed path to the dll in question when using RegSvr32.

e.g. Instead of RegSvr32 my.dll use RegSvr32 c:\mydlllocation\my.dll
