Right. That's about all you get. You can always throw an exception that contains
useful source information, including using those macros.

Hi,
Can any one tell me how to differentiate messagebox dialog from other dialogs.
Thanks in advance.
|
|
|
|
|
why do you have any of your dialogs which look like messagebox?
|
|
|
|
|
As the MessageBox comes from CWnd and CDialog is a CWnd derived class but "independant" you can try
CDialog* pDlg = (CDialog*) GetActiveWindow ();
if (pDlg->IsKindOf(RUNTIME_CLASS(CDialog)))
else
Another way to do the difference is the first member of both possibilites. By MessageBox the first member is a handler o a window hWnd, and in a DialogBox this handler is of the application instance hInstance
Hope it helps
Greetings.

MessageBox is type of dialog. but you don't need template to create it as it required by Dialog. plus a single api call i.e. MessageBox will create the message box for you!

Hi all,
I made this function of getting a unicode MAPI property:
LPMESSAGE msg = NULL;
wstring subj;
HRESULT hrProperty;
LPSPropValue lpPropValue = NULL;
hrProperty = HrGetOneProp(m_Message->Interface(), PR_SUBJECT_W, &lpPropValue);
if (hrProperty == S_OK)
{
subj = static_cast<wstring>(lpPropValue[0].Value.lpszW);
}
return _bstr_t(subj.c_str());
now I need the subj value for SetSubject(Subj.c_str(),codePage) from altmime however when I pass the value of subj to a string it loses it's contents(I am retrieving asian characters) it turns into ??? from the original value.
Help please,
Jj

offcourse it will lose every thing as string can have 256 value per character and wide string have 2 power <superscript>16 values per character. so if you are using asian character set ..then work with wide string only

Does ShowWindow (FALSE) help when used in your dialog?

No, ShowWindow(SW_HIDE) does not work
|
|
|
|

It should... but ok.
Then... what about getting the DesktopRect and moving the dialog with MoveWindow (...) or with SetWindowPos(...) outside the visible area?
Greetings.

he is right, SW_HIDE will not work for Dialog bix, reason behind it is that when OnIntDialog complete it call it show the Dialog Box. so you have write some other mechanism to do so.. see here http://www.codeproject.com/dialog/dlgboxtricks.asp[^]

You have access to the command line arguments at startup.
If you determine you don't want a GUI window to show then you shouldn't
show the window.
Create your main window without the WS_VISIBLE style. If you want the main
window to show, use ShowWindow(SW_SHOW).
If your main window is a modal dialog, don't call DoModal().

Have you considered the A2W() macro?

Hi guys
How to detect cd presence in CD Drive.if any code is available that is greatful.
Thnaks in advance
RYK
|
|
|
|
|
|
see if the following logic works.
say for exmple, your CD drive is "G"
_chdir("G:");
_findfirst();//not sure about the parameters. find them out. otherwise i have to refer my backups.
if find first detects something, then, cd is available.
otherwise not.
simple.

Suggestion to the members:
prefix your main thread subject with [SOLVED] if it is solved.
