How about using void pointers?

void * m_Data;

void * operator[]( const int nIndex )
{

return m_Data+(sizeof (WHATEVER WE ARE CURRENTLY USING)*nIndex);
}

a = (double)*(vec[0]);
or
a = (char)*(vec[0]);

This is Unix terminology. Windows is a multitasking OS, so there is no concept of a processing running in the background or in the foreground. If a process is running, it is running, period.

Now, a process with no UI is a totally different matter.

I have searched the world for a solution to format a CString value of the format "longdate" to "shortdate".
"YYYY-MM-DD hh:ss" to "YYYY-MM-DD".

I'm not using .net.

It should be simple, but not for me... Confused | :confused:

Yes thanks!

I found a solution:

COleDateTime dt;
CString theDate=pProject->getProjectCompletionDate();
dt.ParseDateTime(theDate);
if (dt.GetStatus()==COleDateTime::valid)
theDate=dt.Format(VAR_DATEVALUEONLY);
else
theDate="";

Well, if the format is fixed, you can simply truncate the string at the space between the day digits and the hour digits.

CString sTD = _T( "2006-01-02 12:34" );  // Example DT In "YYYY-MM-DD hh:ss" Format
 
sTD.Delete( 10 );

Peace!

Hi ,
We all know windows system supports left mouse button drag and drop operation.
And we still can let our own application to support drag and drop operation.
My issue is can we hook system's Drag&drop operation when user drag&drop files between two system folders.
For example,User does drag&drop operation in two system owner folder(eg, C: source folder and D: target folder). Can we get draged data information when mouse is moveing in C folder region.

Any advice is welcome!

Thanks,

Can you edit your message and check the box that says "Do not treat <'s as HTML tags" otherwise we can't see your XML.

cleanly teminating an invisible dialog application;

I have used following technique to make dialog invisible
at startup; which i have taken from Nishant Sivakumar's
article "Some handy dialog box tricks, tips and
workarounds".

void CTest_deleteDlg::OnWindowPosChanging(WINDOWPOS FAR* lpwndpos)
{
if(!visible)
lpwndpos->flags &= ~SWP_SHOWWINDOW;

CDialog::OnWindowPosChanging(lpwndpos);
}

The problem is how can i terminate cleanly an invisible dialog application

I have tried following;

1. Sending postmessage(wm_close) to dialog but it
donot work; probably because the dialog is invisible.

2. OnOK() is also not working.

3. Showing the dialog and immediately and sending close message produces
a splash therefore avoided.

3. exit(1) works fine but I am not sure that it teminates
application cleanly or not so, I want to avoid this.

4. calling the Exit instance of main application even donot work!

((CMYApp*)AfxGetApp())->ExitInstance();

this should work because I am calling application object exit? but it wont?

I am looking for a clean solution to terminate a hidden dialog application.

Thanks in advance. Rose | [Rose]

You could try: (Haven't tested it)
PostQuitMessage(0);

this is this.

Try PostQuitMessage(). It will destroy the main window and terminate the application.

In the OnPaint method:

if (IsIconic())<br />
{<br />
//...whatever<br />
}<br />
else<br />
{<br />
CPaintDC dc(this); // Add this line. Then you can use the dc, which seems similar to CDC.<br />
CDialog::OnPaint();<br />
}

this is this.
