Try using CException instead. The exception might not be from CFile.

Check this article[^]. Try using TRY and CATCH macros see if it helps. Unsure | :~

Or have you used catch(...)?

Check out SetErrorMode()
I think you can use this:

<br />
SetErrorMode(SEM_FAILCRITICALERRORS);<br />
...... Do stuff, such as filling up the disk and get the errorcode.<br />
SetErrorMode(0);<br />

Win CE doesnot support SetErrorMode().

Hello,

Either u can write

try
{
}
catch(...)
{
}

or u can write

<code>__try
{
}
__except(1)
{
	CString str;
	str.Format(_T("%x"),GetExceptionCode());
	AfxMessageBox(str);
}</code>

For MFC, use TRY/CATCH instead.

I used class CFileDialog in order to open file and save file in my application
But when I select CFileDialog with mode open (flag bOpenFileDialog = TRUE),change size it and close.
I select CFileDialog with mode save as (flag bOpenFileDialog = FALSE).
size of save as dialog exactly the same like size of open dialog when close.
Can I avoid this behaviour?
Please help me!

The file dialog is a system dialog and the size is saved in the registry for each app that uses it. To change the behaviour you have to subclass the file dialog and do all the saving and restoring of the dialog sizes yourself. There are articles about subclassing the CFileDialog here on CP, do a search.

Can you tell me more clearly about key of system dialog in registry .
I have tried subclassing the CFileDialog and set size of it in OnDestroy() and on OnInitDialog() but not successed.

What didn't work? It works for me.

I think you could specify a hook, and in that procedure, respond to the WM_INITDIALOG message. In addition, you'll most likely need to use GetOpenFileName() instead of CFileDialog.

Friends,
I've a simple dialog based application and when user right clicks on the dialog window, a menu gets opened.
Now the menu gets closed when user presses escape key or click on the dialog. I want to detect that the menu has been closed.
How can i determine that the menu has been closed ? Is there any such event ?

Hi,

int id;
const int ********::get_id() const
{
return id;
}

I want to do these operations.
**** gh;
int th = gh.get_id (how is it possibele to type cast)
int th =10;

if (th == gh.get_id) (how is it possible to compare)

COleDateTime& CTableInfo::edit_date()
{
return edit_date;
}
CtableInfo in;

COleDateTime ct;

ct = in.edit_date(); //this is not happening and
//'=' : cannot convert from 'class COleDateTime (__thiscall
CToleranceTableInfo::*)(void)' to 'class COleDateTime *'

give me some solution...

thanks in advance..

bye

to understand problem easily, can you reword your problem. Are ***** placeholders for something ?

Cinfo::get_id() is a member function, so to call it you have to use the parameters at the end to denote the parameter list. If not you are getting the address of the function.

int th = gh.get_id();

kk_mfc wrote:
COleDateTime CTableInfo::edit_date()

Give your function and member variables different names. Right now the function is trying to return it's own address, cast to a COleDateTime pointer. It can not do that.

Thanks ...

the first solution worked out...

i am already using a different variable name...

COleDateTime CTableInfo::get_edit_date()
{
return m_edit_date;
}

COleDateTime dt;

CTableInfo cy;

dt = cy.get_edit_date();
error mess binary '=' : no operator defined which takes a right-hand operand of type 'class COleDateTime' (or there is no acceptable conversion)

and i am trying to compare the current date with previous date

if(dt == cy.get_edit_date())
if(dt > cy.get_edit_date())

error
binary '==' : no operator defined which takes a left-hand operand of type 'class COleDateTime' (or there is no acceptable conversion)

What are the error numbers that the compiler gives you (C####)? Looking up those numbers in MSDN can be very helpful in figuring out the errors.

The code you've shown is correct. The problem is related to other code that you've not shown. Change your CTableInfo class such that only necessary statements are present. In other words, remove the statements that have nothing to do with the problem.

You are not described complete code here.
This code with some spelling correction should work.

kk_mfc wrote:

I think you want to use ,

if (th == gh.get_id ())
{
}

kk_mfc wrote:
COleDateTime CTableInfo::edit_date()
{
return edit_date;
}

You have kept class member variable name and function name same.

kk_mfc wrote:
ct = in.edit_date(); //this is not happening and
//'=' : cannot convert from 'class COleDateTime (__thiscall
CToleranceTableInfo::*)(void)' to 'class COleDateTime *'

If you corrected above mistake , this error should not come.
whats CToleranceTableInfo
? Thats why I said, you have not desribed your problem clearly.
