How many time my application is run in memory (SOLVED)

[Horizon]

Hi,

I want to find out How many time my application is run in memory.

Can anyone help me where to start?

Thanks.

Do you mean how long one of your programs has been running?

From powershell:

New-TimeSpan -Start (get-process <yourapplication>).StartTime

Internal to the program? I would just set a variable with DateTime() on entry, then diff that with current DateTime() to get total runtime of the app.

And I just realized I may have misinterpreted the question. Are you asking how many instances of your application are in memory? (and not how long it's been running as I commented about.)

This can also still be done easily with powershell, though I'd need to look that up.

(Get-Process | Where-Object {$_.Name -eq 'YourApp'}).count

Yes this is.

As far as I know, in order to run powershell, firstly, we should install it. I could not install it to customer computer. I need something different.

Thank you.

Dear Hakan,

Do you mean that you want to allow just one single execution of your app ?

Hi Antonio,

This is not my purpose. My application can run more than once instances.

I want to copy my app exe from server by using batch file at ConvertW32.exe.

Code: Select all  Expand view

                        cRelauFle := cFilePath(GetModuleFileName( GetInstance() ))+'\Relaunch.Bat'
                        hFile := FCreate( cRelauFle, 0 ) // 0 Normal/Default,Read/Write
                        if hFile >= 0
                            FWrite( hFile, "COPY "+::cRoot+"Convert32.exe "+cFilePath(GetModuleFileName( GetInstance() ))+"\Convert32.exe /Y" +CRLF )
                            FWrite( hFile, GetModuleFileName( GetInstance() ) +CRLF )
                            FWrite( hFile, "exit" +CRLF )
                            FClose( hFile )
                            SysRefresh()
                            *--
                            WinExec( cRelauFle, 0 ) // 0 not show Cmd.exe Window, 1 yes
                        ENDIF          
                        QUIT

for example, my customer runs two instance of my application. in this situation, I release a new version on server. My customer exit one program and run my application again (or run a new instance of my app), the new version found message comes. I want to find out how many instance of my app. run in memory at this computer. if more than one, I will warn my customer to exit other instances or I will force to close other instances.

Thats my purpose.

Using FindWindow() function find the first instance hWnd.

This code seems to be what you need:

As a rule, the class name of the main window is TWindow (you can make a unique name) And using Enum() to determine the number of running instances of the task

hi,

when run same App "more" than once it will use same "Name" in each Instance

Code: Select all  Expand view

IF HowManyApp("Notepad.exe") > 1
    MsgInfo("more that 1 Instance running ! ")

Code: Select all  Expand view

FUNCTION HowManyApp(cApp)
LOCAL oProcesses, oProcess, oWMI, oLocator
LOCAL nRet := 0

   oLocator := CreateObject( "wbemScripting.SwbemLocator" )
   IF EMPTY( oLocator )
      msginfo( "can not create wbemScripting.SwbemLocator" )
      RETURN 0
   ELSE
      oWMI := oLocator:ConnectServer()
   ENDIF

   IF EMPTY( oWMI )
      msginfo( "can not connect oLocator:ConnectServer()" )
      RETURN 0
   ELSE
      oProcesses = oWMI:ExecQuery( "SELECT * FROM Win32_Process" )

      IF oProcesses:Count > 0
         FOR EACH oProcess in oProcesses
            IF UPPER( TRIM( oProcess:Name ) ) = UPPER( TRIM( cApp ) )
               nRet += 1
            ENDIF
         NEXT
      ENDIF
   ENDIF

   oProcesses := NIL
   oWMI := NIL
   oLocator := NIL
RETURN nRet

Thank you very much Jimmy. It works very well.

Hi Jimmy,

Is it possible to read Open Files in Shared folders via WMI?. (My Computer, Manage, System Tools, Shared folder, Open Files)

Thanks in advance.
