please refer this :-

instead of making global variable.. it is better to use singleton class.!

Is GetParent() returning a valid (i.e., the actual parent) pointer? Note that just because the value is non-NULL does not mean it is valid. Is m_WebSitePagesAry non-empty? Even if it wasn't, nTotalWebPageCount would be 0 (assuming that the answer to my first question is "yes").

Plain C++ doesn't have the reflection capabilities of C# so what you want to do, to be generic, requires the use of symbolic debug information. In other words you can do this but it's not straight forward and will only work in Debug builds with the PDB available. The full process of turning addresses into line numbers and a great deal more is explained in this book by John Robbins[^] and the associated source code will give you what you need. If you can find John's web site it should all be available for free download.
Nothing is exactly what it seems but everything with seems can be unpicked.

Do the __FILE__ and __LINE__ macros help any?

__LINE__ macro gives the line in the catch block not the one from where the exception occurs... __FILE__ does give u the file name though

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[^]
