how to get current application windows title?
-
hi every one, I want to get current application windows title and then show it? through my search,I find out that I should use getforegroundWindow(),but I don't get it how to do that ? I'd appreciate any help.
To use C++ functions you need to do some research into P/Invoke. Here's how to declare the functions you need in C#:
// NativeMethods.cs
using System;
using System.Text;
using System.Runtime.InteropServices;namespace ConsoleApplicationTest
{
internal static class NativeMethods
{
[DllImport("User32.dll")]
public static extern IntPtr GetForegroundWindow();\[DllImport("User32.dll")\] public static extern int GetWindowText(IntPtr hWnd, StringBuilder lpString, int nMaxCount); }}
Usage example:
// Program.cs
using System;
using System.Text;namespace ConsoleApplicationTest
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Press any key to get text");
Console.ReadKey();
IntPtr handle = NativeMethods.GetForegroundWindow();
if (handle != IntPtr.Zero)
{
StringBuilder builder = new StringBuilder(255);
NativeMethods.GetWindowText(handle, builder, builder.Capacity);
Console.WriteLine(builder.ToString());
}
Console.ReadKey();
}
}
}I have used a hardcoded max length of 255. You can use GetWindowText[^] to get the length of the text before getting the text so you won;t be wasting memory with your string builder or risk truncating if it's longer than you expect. I'll leave implementing that (which is simple) as an exercise for you.
