Using ProcessActivityView

ProcessActivityView doesn't require any installation process or additional dll files. In order to start using it, simply run the executable file - ProcessActivityView.exe
After running it, select the process that you want to inspect, and click Ok. After clicking Ok, ProcessActivityView will start to display the information about any file that is opened by the selected process.

Using ProcessActivityView In Windows Vista

ProcessActivityView can work in Vista even when UAC (User Account Control) is turned on, as long as the process that you wish to inspect run in the same account and security context of ProcessActivityView. However, if you want to inspect a process that runs under administrator account, you must also run ProcessActivityView as administrator. (right-click on ProcessActivityView.exe and choose 'Run As Administrator')

How Does It Work ?

After you select a process, ProcessActivityView inject a special helper dll (ProcessActivityViewHelper.dll) into the selected process. This dll intercepts the internal file I/O API of Windows, and sends the information back to ProcessActivityView utility.

Command-Line Options

/RunProcess <exe filename> Run the specified process
/ProcessParams <parameters> Specify parameters for the process that you run with /RunProcess.
/StartImmediately <0 | 1> Specify the "Start Immediately" value (0 or 1).

Translating ProcessActivityView to other languages

In order to translate ProcessActivityView to other language, follow the instructions below:

    A file named ProcessActivityView_lng.ini will be created in the folder of ProcessActivityView utility.
  2. Open the created language file in Notepad or in any other text editor.
  3. Translate all string entries to the desired language. Optionally, you can also add your name and/or a link to your Web site. (TranslatorName and TranslatorURL values) If you add this information, it'll be used in the 'About' window.
  4. After you finish the translation, Run ProcessActivityView, and all translated strings will be loaded from the language file.
