How to set foreground window by partial title name> - c#

I want to bring another application into the foreground, however, I only have a partial name of the window. Back in the day, I'd hook into the EnumWindows API and look for what I needed.
Is there a way to do this better in C#? An example would be great.

This should do the job:
[DllImport("user32.dll", EntryPoint="SystemParametersInfo")]
public static extern bool SystemParametersInfo(uint uiAction, uint uiParam, uint pvParam, uint fWinIni);
[DllImport("user32.dll", EntryPoint="SetForegroundWindow")]
public static extern bool SetForegroundWindow(IntPtr hWnd);
[DllImport("User32.dll", EntryPoint="ShowWindowAsync")]
private static extern bool ShowWindowAsync(IntPtr hWnd, int cmdShow);
private const int WS_SHOWNORMAL = 1;
private const int SW_SHOWMAXIMIZED = 3;
[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool GetWindowPlacement(IntPtr hWnd, ref WINDOWPLACEMENT lpwndpl);
private struct WINDOWPLACEMENT
{
public int length;
public int flags;
public int showCmd;
public System.Drawing.Point ptMinPosition;
public System.Drawing.Point ptMaxPosition;
public System.Drawing.Rectangle rcNormalPosition;
}
Process[] processes = Process.GetProcesses();
foreach(Process p in processes){
if(p.MainWindowTitle.Contains("nice_title")){
WINDOWPLACEMENT wp = new WINDOWPLACEMENT();
placement.length = Marshal.SizeOf(placement);
GetWindowPlacement(p.MainWindowHandle, ref placement);
int proposedPlacement = wp.showCmd;
if (wp.showCmd == SW_SHOWMINIMIZED)
proposedPlacement = SW_SHOWMAXIMIZED;
SystemParametersInfo( (uint) 0x2001, 0, 0, 0x0002 | 0x0001);
ShowWindowAsync(p.MainWindowHandle, proposedPlacement);
SetForegroundWindow(p.MainWindowHandle);
SystemParametersInfo( (uint) 0x2001, 200000, 200000, 0x0002 | 0x0001);
}
}

Set Height, Width and screen location of any window

Hi I looked into this guy question and got some of my answer but I would like to instead of resizing explorer I would like to resize discord or firefox for instance
private void windowsPos(string name, Rect pos){
foreach (SHDocVw.InternetExplorer window in new SHDocVw.ShellWindows()){
if (Path.GetFileNameWithoutExtension(window.FullName).ToLowerInvariant() == name){
window.Left = pos.Left;
window.Top = pos.Top;
window.Width = pos.Width;
window.Height = pos.Height;
}
}
}
But this works only for explorer I tried other exe but it works only for explorer ... can someone help me adapt this code to my requirements ?
Thank you #zezba9000 & #NetMage your answsers were the ones that worked ... I went on PInvoke - EnumWindows to get the general idea of how it works and the used Reed's answer to get to this code :
public class SearchData{
public string Title;
public IntPtr hWnd;
}
private delegate bool EnumWindowsProc(IntPtr hWnd, ref SearchData data);
[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
private static extern bool EnumWindows(EnumWindowsProc lpEnumFunc, ref SearchData data);
[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
public static extern int GetWindowText(IntPtr hWnd, StringBuilder lpString, int nMaxCount);
[DllImport("user32.dll", EntryPoint = "SetWindowPos")]
public static extern IntPtr SetWindowPos(IntPtr hWnd, int hWndInsertAfter, int x, int Y, int cx, int cy, int wFlags);
private void test(){
IntPtr hwnd = SearchForWindow("Discord");
SetWindowPos(hwnd, 0, 50, 175, 1000, 750, 0x0040);
}
public IntPtr SearchForWindow(string title){
SearchData sd = new SearchData { Title = title };
EnumWindows(new EnumWindowsProc(EnumProc), ref sd);
return sd.hWnd;
}
public bool EnumProc(IntPtr hWnd, ref SearchData data){
StringBuilder sb = new StringBuilder(1024);
GetWindowText(hWnd, sb, sb.Capacity);
if (sb.ToString().Contains(data.Title)){
data.hWnd = hWnd;
return false;
}
else return true;
}
Also #Jimi I tried your approach but I could not work with it because it could not find Automation in the System.Windows namespace

Simulate mouse click synchronously

I tried to use mouse_event() function, but it seems that it works asynchronously.
Below is my code (the problem is in Main method).
I set mouse position and simulate click, but my code returns the previous window (in the last line) even before click simulation happen.
How to overcome this asynchrony without suspending thread for 100 milliseconds?
using System;
using System.Diagnostics;
using System.Runtime.InteropServices;
using System.Threading;

//remember current foreground window
IntPtr previousForegroundWindow = GetForegroundWindow();
IntPtr browserWindowHandle = GetBrowserWindow();
//set browser window to foreground to make a click in it
ForceActivateWindow(browserWindowHandle);
//make a click
SetCursorPos(150, 20);
mouse_event(LEFT_DOWN, 0, 0, 0, 0);
mouse_event(LEFT_UP, 0, 0, 0, 0);
//Thread.Sleep(100); //if I uncomment this line then everything works perfectly
//return previous foreground window to top
ForceActivateWindow(browserWindowHandle);
}

How to minimize/maximize opened Applications

I have list of open Applications. To get this list i have used following code
internal static class NativeMethods
{
public static readonly Int32 GWL_STYLE = -16;
public static readonly UInt64 WS_VISIBLE = 0x10000000L;
public static readonly UInt64 WS_BORDER = 0x00800000L;
public static readonly UInt64 DESIRED_WS = WS_BORDER | WS_VISIBLE;
public delegate Boolean EnumWindowsCallback(IntPtr hwnd, Int32 lParam);
public static List<WindowWrapper> GetAllWindows()
{
List<WindowWrapper> windows = new List<WindowWrapper>();
StringBuilder buffer = new StringBuilder(100);
EnumWindows(delegate(IntPtr hwnd, Int32 lParam)
{
if ((GetWindowLongA(hwnd, GWL_STYLE) & DESIRED_WS) == DESIRED_WS)
{
GetWindowText(hwnd, buffer, buffer.Capacity);
WindowWrapper wnd = new WindowWrapper();
wnd.handle = hwnd;
wnd.title = buffer.ToString();
windows.Add(wnd);
}
return true;
}, 0);
return windows;
}
[DllImport("user32.dll")]
static extern Int32 EnumWindows(EnumWindowsCallback lpEnumFunc, Int32 lParam);
[DllImport("user32.dll")]
public static extern void GetWindowText(IntPtr hWnd, StringBuilder lpString, Int32 nMaxCount);
[DllImport("user32.dll")]
static extern UInt64 GetWindowLongA(IntPtr hWnd, Int32 nIndex);
}
public class WindowWrapper : IWin32Window
{
internal IntPtr handle;
internal String title;
public IntPtr Handle
{
get { return handle; }
}
public String Title
{
get { return title; }
}
}
to call this i used following code
foreach (var wnd in NativeMethods.GetAllWindows())
{
string caption = wnd.title;
string handle = wnd.Handle
// Add this caption and handle to list
}
Now, User will select any of the opened window from the list and my task is to read caption of the selected window, get handle of process and maximize/minimize or close window. How can I do this.
You can use findwindowbycaption to get the handle then maximize or minimize with showwindow
private const int SW_MAXIMIZE = 3;
private const int SW_MINIMIZE = 6;
// more here: http://www.pinvoke.net/default.aspx/user32.showwindow
[DllImport("user32.dll", EntryPoint = "FindWindow")]
public static extern IntPtr FindWindowByCaption(IntPtr ZeroOnly, string lpWindowName);
[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);
Then in your code you use this:
IntPtr hwnd = FindWindowByCaption(IntPtr.Zero, "The window title");
ShowWindow(hwnd, SW_MAXIMIZE);
Although it seems you already have the window handle by using EnumWindows in that case you would only need:
ShowWindow(windows[i].handle, SW_MAXIMIZE);
i is the index of the window.
to close the window you will use:
[DllImport("user32.dll", CharSet = CharSet.Unicode, SetLastError=true)]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool DestroyWindow(IntPtr hwnd);
in the code:
DestroyWindow(hwnd) //or DestroyWindow(windows[i].handle)
this is the unmanaged version of system.windows.forms.form.close()
or you can use:
Process [] proc Process.GetProcessesByName("process name");
proc[0].Kill();
or you can use:
static uint WM_CLOSE = 0x0010;
[return: MarshalAs(UnmanagedType.Bool)]
[DllImport("user32.dll", SetLastError = true)]
static extern bool PostMessage(IntPtr hWnd, uint Msg, IntPtr wParam, IntPtr lParam);
in code:
PostMessage(hWnd, WM_CLOSE, IntPtr.Zero, IntPtr.Zero);
You may use native method ShowWindow with SW_MAXIMIZE, SW_MINIMIZE for ncmdShow
Take a look at http://msdn.microsoft.com/en-us/library/windows/desktop/ms633548(v=vs.85).aspx
private const int SW_MAXIMIZE = 3;
private const int SW_MINIMIZE = 6;
[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool ShowWindow(IntPtr hWnd, ShowWindowCommands nCmdShow);
// in your code
ShowWindow(wnd.Handle, SW_MAXIMIZE);
you can use ShowWindowAsync
private const int SW_SHOWNORMAL = 1;
private const int SW_SHOWMINIMIZED = 2;
private const int SW_SHOWMAXIMIZED = 3;
[DllImport("user32.dll")]
private static extern bool ShowWindowAsync(IntPtr hWnd, int nCmdShow);
ShowWindowAsync(wnd.Handle, SW_SHOWMINIMIZED );
and it's better and to use
var openWindows = Process.GetProcesses().Where(process=> String.IsNullOrEmpty(process.MainWindowTitle)==false);
to get opened windows
I have test MainWindowTitle in Porcess and it helps to search on window given it's caption.
var handles = Process.GetProcesses().Where(x => x.MainWindowTitle == "Untitled - Notepad").Select(y=>y.Handle).ToList();

GDI Write Bitmap to File in C#

I'm trying to Capture an Image from a window given the Handle/DC. I want to capture the Image with all the transparency and pixels so I decided I'd use GDI/GDI+.
The below code is what I have, but when it "writes" the bitmap, it writes it wrong :S In other words, the file is unreadable. It is blank. Yet it is 20kb in size :S
Any ideas what is wrong?

If you're looking for a quick band-aid fix to get this done (it just needs to work, not used often, etc) consider just loading the image back into .NET and re-saving it with PNG compression enabled. The .NET framework will handle this for you and the file size will be a lot more optimal. Of course, if this is for a real-time application this isn't ideal.

How to remove the MenuBar of an application using windows API?

I am using the below code to remove the Title Bar of an application, which is working perfectly for notepad. Now i want to remove the Menu Bar also. How to achieve it ?
//Finds a window by class name
[DllImport("USER32.DLL")]
public static extern IntPtr FindWindow(string lpClassName, string lpWindowName);
//Sets a window to be a child window of another window
[DllImport("USER32.DLL")]
public static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent);
//Sets window attributes
[DllImport("USER32.DLL")]
public static extern int SetWindowLong(IntPtr hWnd, int nIndex, int dwNewLong);
//Gets window attributes
[DllImport("USER32.DLL")]
public static extern int GetWindowLong(IntPtr hWnd, int nIndex);
[DllImport("user32.dll", EntryPoint = "FindWindow", SetLastError = true)]
static extern IntPtr FindWindowByCaption(IntPtr ZeroOnly, string lpWindowName);
//assorted constants needed
public static int GWL_STYLE = -16;
public static int WS_BORDER = 0x00800000; //window with border
public static int WS_DLGFRAME = 0x00400000; //window with double border but no title
public static int WS_CAPTION = WS_BORDER | WS_DLGFRAME; //window with a title bar
public void WindowsReStyle()
{
Process[] Procs = Process.GetProcesses();
foreach (Process proc in Procs)
{
if (proc.ProcessName.StartsWith("notepad"))
{
IntPtr pFoundWindow = proc.MainWindowHandle;
int style = GetWindowLong(pFoundWindow, GWL_STYLE);
SetWindowLong(pFoundWindow, GWL_STYLE, (style & ~WS_CAPTION));
}
}
}
You can't hide them, you will need to remove them using the API instead, YMMV on the result of doing this;
[DllImport("USER32.DLL")]
public static extern IntPtr FindWindow(string lpClassName, string lpWindowName);

public static uint MF_BYPOSITION = 0x400;
public static uint MF_REMOVE = 0x1000;
public static void WindowsReStyle() {
Process[] Procs = Process.GetProcesses();
foreach (Process proc in Procs) {
if (proc.ProcessName.StartsWith("notepad")) {
//get menu
IntPtr HMENU = GetMenu(proc.MainWindowHandle);
//get item count
int count = GetMenuItemCount(HMENU);
//loop & remove
for (int i = 0; i < count; i++)
RemoveMenu(HMENU, 0, (MF_BYPOSITION | MF_REMOVE));
//force a redraw
DrawMenuBar(proc.MainWindowHandle);
}
}
}
