How To Get PID From Window Title

by ADMIN 33 views

Introduction

When dealing with multiple instances of the same application on Windows 10, it can be challenging to identify and manage each instance separately. This is particularly true when the application is a third-party software that does not provide a unique identifier or a built-in feature to differentiate between instances. In such cases, the window title becomes a crucial piece of information that can be used to identify and manage each instance. In this article, we will explore how to get the Process ID (PID) from the window title of a third-party application on Windows 10.

Understanding Process ID (PID)

Before we dive into the steps to get the PID from the window title, let's understand what a Process ID (PID) is. A Process ID (PID) is a unique number assigned to each process running on a computer. It is used by the operating system to identify and manage each process. The PID is a 32-bit or 64-bit number that is unique for each process and is used to communicate with the process.

Why Get PID from Window Title?

Getting the PID from the window title is useful in several scenarios:

  • Identifying multiple instances: When you have multiple instances of the same application running, getting the PID from the window title helps you identify and manage each instance separately.
  • Debugging and troubleshooting: When an application freezes or crashes, getting the PID from the window title helps you identify the process and debug or troubleshoot the issue.
  • Managing system resources: Getting the PID from the window title helps you manage system resources, such as memory and CPU usage, for each instance of the application.

Method 1: Using Task Manager

The Task Manager is a built-in utility on Windows 10 that provides information about running processes, including their PIDs. You can use the Task Manager to get the PID from the window title of a third-party application.

Step 1: Open Task Manager

To open the Task Manager, press the Ctrl + Shift + Esc keys on your keyboard or right-click on the taskbar and select Task Manager.

Step 2: Switch to the Processes Tab

In the Task Manager, switch to the Processes tab. This tab displays a list of all running processes on your system, including their PIDs.

Step 3: Filter Processes by Window Title

To filter processes by window title, click on the Filter button at the top of the Processes tab and select Window title from the dropdown menu. Enter the window title of the application you want to identify in the Window title field.

Step 4: Get PID from Window Title

Once you have filtered the processes by window title, you can get the PID from the window title by looking at the PID column in the Processes tab.

Method 2: Using PowerShell

PowerShell is a powerful command-line shell and scripting language on Windows 10 that provides a lot of flexibility and control over system resources. You can use PowerShell to get the PID from the window title of a third-party application.

Step 1: Open PowerShell

To open PowerShell, press the Windows + R keys on your keyboard, type powershell, and press Enter.

Step 2: Use the Get-Process cmdlet

To get the PID from the window title, use the Get-Process cmdlet with the -Name parameter to specify the window title of the application you want to identify.

Get-Process -Name "Application Window Title"

Replace Application Window Title with the actual window title of the application you want to identify.

Step 3: Get PID from Window Title

Once you have run the Get-Process cmdlet, you can get the PID from the window title by looking at the Id property of the process object.

Method 3: Using Windows API

The Windows API provides a lot of functionality for interacting with the Windows operating system, including getting the PID from the window title of a third-party application. You can use the Windows API to get the PID from the window title by using the GetWindowThreadProcessId function.

Step 1: Include the Windows API Header File

To use the Windows API, you need to include the windows.h header file in your code.

#include <windows.h>

Step 2: Get the PID from the Window Title

To get the PID from the window title, use the GetWindowThreadProcessId function to get the PID of the process that owns the window with the specified title.

DWORD GetPidFromWindowTitle(HWND hWnd)
{
    DWORD pid = 0;
    GetWindowThreadProcessId(hWnd, &pid);
    return pid;
}

Replace HWND hWnd with the actual window handle of the application you want to identify.

Conclusion

Q: What is a Process ID (PID)?

A: A Process ID (PID) is a unique number assigned to each process running on a computer. It is used by the operating system to identify and manage each process.

Q: Why do I need to get the PID from the window title?

A: You need to get the PID from the window title to identify and manage each instance of a third-party application running on your system. This is particularly useful when you have multiple instances of the same application running and you need to debug or troubleshoot an issue.

Q: Can I get the PID from the window title of any application?

A: Yes, you can get the PID from the window title of any application running on your system. However, the method you use to get the PID may vary depending on the application and the operating system you are using.

Q: How do I get the PID from the window title using the Task Manager?

A: To get the PID from the window title using the Task Manager, follow these steps:

  1. Open the Task Manager by pressing Ctrl + Shift + Esc keys on your keyboard or right-clicking on the taskbar and selecting Task Manager.

  3. Click on the Filter button at the top of the Processes tab and select Window title from the dropdown menu.
  4. Enter the window title of the application you want to identify in the Window title field.
  5. Look at the PID column in the Processes tab to get the PID of the process.

Q: How do I get the PID from the window title using PowerShell?

A: To get the PID from the window title using PowerShell, follow these steps:

  1. Open PowerShell by pressing the Windows + R keys on your keyboard, typing powershell, and pressing Enter.
  2. Use the Get-Process cmdlet with the -Name parameter to specify the window title of the application you want to identify.
Get-Process -Name "Application Window Title"

Replace Application Window Title with the actual window title of the application you want to identify.

Q: How do I get the PID from the window title using the Windows API?

A: To get the PID from the window title using the Windows API, follow these steps:

  1. Include the windows.h header file in your code.

DWORD GetPidFromWindowTitle(HWND hWnd)
{
    DWORD pid = 0;
    GetWindowThreadProcessId(hWnd, &pid);
    return pid;
}

Replace HWND hWnd with the actual window handle of the application you want to identify.

Q: What are the advantages and disadvantages of each method?

A: The advantages and disadvantages of each method are as follows:

  • Task Manager: The Task Manager is a built-in utility on Windows 10 that provides information about running processes, including their PIDs. The advantage of using the Task Manager is that it is easy to use and provides a lot of information about running processes. The disadvantage of using the Task Manager is that it may not be able to provide the PID of a process that is not running.
  • PowerShell: PowerShell is a powerful command-line shell and scripting language on Windows 10 that provides a lot of flexibility and control over system resources.
