First of all... Thanks. After reading you I have notice that is not as good as I thought.

The problem I have is that the WriteTo functions have to be in a DLL for security to avoid as many problems as possible.

Why is it so ? Which security problems are you talking about ? Putting the code in the dll won't change anything.
That's what my chef want. I explain it better. He want that the programm has the functionality to write down into a PLC, but he wants this functionality to depend on a dll. So that anyone can use my software to write down into the PLC if they don't have our dll. So the programm should work with or without the dll in the folder. But the functionality should be only available when it is there.
Cedric Moonen wrote:
Thus, for both scenarios, it doesn,t make any sense to call a function from your dll to see if it is present (because if you come to the point were you are able to call a function from the dll, then it means that your dll is present).
You are totally right, I don't know what I was thinking about
I will look for info about the LoadLibrary and GetProcAddress. Actually if the return value is NULL when dll is not there... then I can anyways choose between function and messagebox. And that's exactly what I wanted. Thanks

how do i set focus in one of my edit control in property sheet
|

You shouldn't use SetFocus in dialogs. See here[^] for details.

Assume the ID of your edit control is IDC_EDIT_NAMETAG,
to set the focus do the following:
CWnd* pEditCtrl = GetDlgItem(IDC_EDIT_NAMETAG);
pEditCtrl->SetFocus();

GetDlgItem( ID )->SetCapture();
Where ID is the id Of the Edit control
ok.

Purpose of SetCapture() API is different.Did you really mean SetCapture itself?
|
|
|
|
|
Sorry,i was wrong.
code is like that
CEdit* clEdit = (CEdit*)getDlgItem( ID );
clEdit->SetFocus();
sorry again for mistake.
Thanks.

To get more/better behavior than SetFocus() with edit controls,
I would recommend CDialog::GotoDlgCtrl() (MFC) or WM_NEXTDLGCTL (Win32).

And where are you stuck exactly ? Do you know the protocol you need to use to communicate with the modem (probably AT commands) ?
