Yep, that what I have done pal.

And what were results?
(1) n is proper assigned, i.e. it corrensponds to the numerical value of the argument you passed.
(2) Lets suppose n=1. Did execution reach

m_Add.addNumbers();

line?
(3) if the answer to point (2) is yes, had you follow execution inside your method? What did happen?

I think you can figure out some other interesting tests.

Yes, everything works fine. I couldn't find where the error. So what I have done is write another application, follows same steps which as previously do. It works.

I don't know why is that. But Little worried about another thing. I try change the argument to text. Something like this,

func.exe sum

rather than use of a number as argument. Set the arguments as 'sum' and tried it. But no luck. Is there any additional changes I have to done, which I don't have done in previous case.

I appreciate your help all the time...

Yes, you have to test against strings, change

int n;
n = atoi(argv[1]);

switch(n)
{
case 1:
  //func1();
  m_Add.addNumbers();
  break;
case 2:
  //func2();
  m_Add.diffNumbers();
  break;
default:
  cout << "Invalid argument" << endl;
break;
}

into

if ( strcmp(argv[1], "sum") == 0 )
{
  m_Add.addNumbers();
}
else if ( strcmp(argv[1], "diff") == 0) )
{
  m_Add.diffNumbers();
}
else
{
  cout << "Invalid argument" << endl;
}

I've test this, but gives an error on following code line.

Error is,

'_tcscmp' : cannot convert parameter 2 from 'bool' to 'const char *'

Opening a running process programmatically

I am a beginner who wants to restore the main window of a clock program that resides in the System Tray when running. What I want to do programatically is done normally by right clicking on the clock program's icon in the System Tray, then selecting "Restore Main Window" from the context menu.

I have tried many things, and the closest I can get is using SetForegroundWindow, which will only work when I have already selected "Restore Main Window" from the context menu and then minimized the restored main window.

I think I must be missing some fundamental concept about what I am trying to do.

Consider the pseudocode below...

void MyApp::OnLaunchSysTrayApp<br />
{<br />
CWnd*m_hWnd = FindWindow(NULL, "System Tray Application Name")<br />
if (m_hWnd)<br />
{<br />
m_hWnd->SetForegroundWindow();   //Displays restored main window if not on top<br />
//m_hWnd->GetWindow(NULL);       //Fails<br />
//m_hWnd->ShowWindow(SW_RESTORE);    //Fails<br />
//m_hWnd->SetActiveWindow();    //Fails<br />
<br />
BOOL m_bIconic;<br />
m_bIconic=m_hWnd->IsIconic()<br />
if (m_bIconic)<br />
{<br />
//m_hWnd->GetWindow(NULL);       //Fails<br />
//m_hWnd->ShowWindow(SW_RESTORE);    //Fails<br />
//m_hWnd->SetActiveWindow();    //Fails<br />
} etc.<br />
}<br />
}<br />
<br />

I would appreciate any suggestions about how I might achieve my goal, or information about whatever basic concept I (probably) currently fail to understand.

Thank you.

Too much of this depends on the particular application to usefully answer.

Maybe the clock window is destroyed, or maybe it is the main window for the application but is hidden. Maybe, maybe...

In short, I don;t think there is a generic way of doing this.

Try posting the SW_RESTORE command to the application.

The only way of stopping the display is simply not to display anything in your code.
You'll have to manage it yourself: in your code, wait for the user to press a key before going to the next step.

Can't you just scroll the console window up (with the mouse) to see the older text?

1/ There may be good reasons for resticting the size of an application. But the position? I officially don't want to use it.

2/ Have a look at WM_WINDOWPOSCHANGING to reset window movement, or override WM_NCHITTEST to tell windows this is not a draggable window bit.

3/ See (1) again. You'd better have a VERY good reason to do this, or you'll get hate vibes from customers.

CFile title

17-Jan-08 16:41

Hi all,

What I know about CFile::GetFileTitle(); that it gives the title(name without the extension) of a CFile. So what is happened here in this code. I found this on MSDN.

Try
   {
      // Try to open the file.
      CFile sysFile(_T("\\My Documents\\FOO.DAT"), CFile::modeRead);

      // Print out path name and title information.
      _tprintf(_T("Path is : \"%s\"\n"), (LPCTSTR) sysFile.GetFilePath());
      _tprintf(_T("Name is : \"%s\"\n"), (LPCTSTR) sysFile.GetFileName());
      _tprintf(_T("Title is: \"%s\"\n"), (LPCTSTR) sysFile.GetFileTitle());

      // Close the file handle.
      sysFile.Close();
   }
   CATCH(CFileException* pEx)
   {
      // If an error occurs, just make a message box.
      pEx->ReportError();
}

Output
Path is : "\My Documents\FOO.DAT"
Name is : "FOO.DAT"
Title is: "FOO.DAT"

Here output for Title is FOO.DAT, is it correct. Frown | :(

Here is the link I get it on MSDN Library 2004.

Have you looked at MSDN to find out what it says GetFileName and GetFileTitle actually DO?

Then you'll be able to answer the question yourself.

That depends on how you've got Windows configured to show file extensions. The GetFileTitle() method is simply respecting that setting. If you don't want the extension displayed, regardless of Windows' setting, you'll have to remove it yourself.
