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.

You can use GetConsoleScreenBufferInfo for getting the screen size.

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

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.

is this loop right?

Dear all

the following is my part code, when i run, d[m] is minimum value of an double array named c of 150x3. actually total of num1, num2 and num3 are 150..but here why num1 = 150, num2 =151,num3=151...

for (int m = 0; m < 150; m++)
{
if ( d[m] == c[m][0])
sum1 = c[m][0];
sum1 = sum1 + 1;
num1 = num1 + 1;

if ( d[m] == c[m][1])
sum2 = c[m][1];
sum2 = sum1 + 1;
num2 = num1 + 1;

if (d[m] == c[m][2])
sum3 = c[m][2];
sum3 = sum1 + 1;
num3 = num1 + 1;

}
cout<< " "<< num1 << " " << num2 << " " << num3 << endl;

cout << " " << sum1 << " " << sum2 << " " << sum3 << endl;
but the result is following:

num1 num2 num3
150 151 151
sum1 sum2 sum3
1.87 2.89 2.89

"Out of Memory" in the debugger

I'm using Visual C++ 6.0, and am getting an "Out of Memory" error while trying to run in both debug mode and in release mode. Running the release standalone EXE works fine, aside from the bug I'm trying to fix. I've got alot of arrays declared and vectors reserving space. What I'm not understanding is why will it not run in the IDE, but run fine outside of it? I know I can probably try to decrease the size of the arrays and vectors, to see if that can fix the error. But it was running fine a while ago, I changed something unrelated to the array sizes, and then started getting this error. Any help on tracking this down and fixing it so I can run in the IDE would be greatly appreciated.
