I also have a significant other, and she often walks into the room to talk to me while I'm playing video games. I would like to pause the game so that I can give her my undivided attention while she's talking to me, but a lot of games (particularly single-player ones) have these "un-pausable" cut scenes or other areas of the game where the normal pause functionality doesn't work. This annoys both me and her, because I'm supposed to be the computer expert, and it looks like I don't even know how to pause my stupid video game. So usually what ends up happening is either I skip the cut scene and miss the story, or upset my SO by not paying attention to her as well as I should. 9 | 10 | So that is why I wrote Universal Pause Button. It's a very simple Windows desktop app that sits in the system tray. Its icon resembles a pause button. When you hit the actual Pause key (also known as Break) on your keyboard, (you can also define your own custom pause key in the registry,) the program determines which window is currently in the foreground (i.e. your game's window,) and pauses it. No matter where you are in the game. Even in the middle of one of those pesky cutscenes that would otherwise be un-pausable. When you press the key again, the game will un-pause. You can also specify a process by name in the registry to pause and un-pause that process, regardless of whatever the foreground window may be. 11 | 12 | I first wrote this app in 2015, but mostly forgot about it since then. But it has always been my most popular app on Github, so today in 2023 I've come back and rewritten the app from scratch, 8 years later, adding several improvements and requested features along the way. 13 | 14 | Back in 2015, I used this app with The Witcher 3, and it worked great. 15 | 16 | Today in 2023, I used this app with Baldur's Gate 3 and it is still working great. 17 | 18 | However, your mileage may vary. It does not work with every app/game. "Pausing" processes is something that usually only debuggers do, and not every process will react the same way to being paused. Pausing processes may lead to race conditions among the threads of that process, but like I said, testing has been very positive for me so far. I've already gotten great value out of the program, as there are lots of cut scenes in The Witcher 3 that I don't want to skip. The main use case for this app is single player games, as pausing your multi-player game will undoubtedly just get you kicked from the session, as if your computer had just crashed or hung. So don't use it in multi-player games. It also works on applications that are not games at all. 19 | 20 | There are some new registry settings you should be aware of: 21 | 22 | ![Registry](https://github.com/ryanries/UniversalPauseButton/blob/master/registry.png) 23 | 24 | All registry settings are in HKCU\Software\UniversalPauseButton. 25 | 26 | **Debug** 27 | 28 | Type: DWORD 29 | 30 | Default: 0 31 | 32 | Minimum: 0 33 | 34 | Maximum: 1 35 | 36 | 37 | By enabling this Debug setting, the app spawns a debug console that allows you to see all the internal messages generated by UniversalPauseButton. It is mostly intended just for use by me during debugging. But you can turn it on if you are having issues with the app and want to troubleshoot. 38 | 39 | ![Debug Console](https://github.com/ryanries/UniversalPauseButton/blob/master/debugconsole.png) 40 | 41 | **PauseKey** 42 | 43 | Type: DWORD 44 | 45 | Default: 0x13 46 | 47 | Minimum: 0x1 48 | 49 | Maximum: 0xFE 50 | 51 | 52 | This is the customizable Pause key. By default, it is 0x13, which is the virtual key code for the Pause/Break key on your keyboard. For a list of virtual key codes so that you can map this to another key, use the virtual key codes defined in the Windows documentation here: https://learn.microsoft.com/en-us/windows/win32/inputdev/virtual-key-codes 53 | 54 | **TrayIcon** 55 | 56 | Type: DWORD 57 | 58 | Default: 1 59 | 60 | Minimum: 0 61 | 62 | Maximum: 1 63 | 64 | 65 | If TrayIcon is enabled, which it is by default, there will be a small system tray icon that looks like a pause button. When you click that icon it will give you a dialog box asking if you want to exit the app. If you turn TrayIcon off, there will be no tray icon, no taskbar icon, no nothing. The app will be completely invisible and in the background. I added this feature because someone requested it, saying that they use a custom shell other than Explorer.exe, and since they didn't have a system tray in their shell, the app wouldn't work. Well, here you go, Mr. Alternative Shell. 66 | 67 | **ProcessNameToPause** 68 | 69 | Type: REG_SZ (String) 70 | 71 | Default: "" (Empty string) 72 | 73 | Minimum: n/a 74 | 75 | Maximum: n/a 76 | 77 | 78 | If ProcessNameToPause is defined, then the app will only pause that process by name, regardless of foreground window. E.g., notepad.exe or mycoolgame.exe. Include the .exe file extension. It expects process name, not Window text. WARNING: In case there are multiple processes with the same name, only the first instance found will be paused. Please don't try dumb things like trying to pause svchost.exe or lsass.exe or csrss.exe... 79 | 80 | **WebPort** 81 | 82 | Type: REG_SZ (String) 83 | 84 | Default: "" (Empty string) 85 | 86 | Minimum: n/a 87 | 88 | Maximum: n/a 89 | 90 | 91 | If WebPort is defined, then the app will open up a port for which another device, such as a phone can connect to. This can be useful for games which take control of the keyboard and do not allow key presses to flow to the Universal Pause Button app. 92 | 93 | Type: DWORD 94 | 95 | Default: 0x0 (Disabled) 96 | 97 | Minimum: 0x0 98 | 99 | Maximum: 0xFFFF 100 | 101 | As always, please try it out, and let me know if you find any bugs or have any feature requests. 102 | 103 | Thanks! -------------------------------------------------------------------------------- /Server.c: -------------------------------------------------------------------------------- 1 | #include 2 | #include 3 | #include 4 | #include 5 | #include 6 | #include 7 | #include 8 | #include 9 | #include 10 | #include "Server.h" 11 | #include "resource.h" 12 | 13 | //for debugging msgs 14 | #include "Main.h" 15 | 16 | #pragma comment(lib, "iphlpapi.lib") 17 | #pragma comment(lib, "ws2_32.lib") 18 | 19 | 20 | 21 | #define BUFFER_SIZE 4096 22 | 23 | // Global variables 24 | bool serverRunning = true; 25 | HANDLE serverThreadHandle; 26 | 27 | static SOCKET serverSocket = INVALID_SOCKET; 28 | 29 | // Response when app is paused 30 | const char* pauseResponse = "1"; 31 | 32 | // Response when app is unpaused 33 | const char* unpauseResponse = "0"; 34 | 35 | const char* htmlResponseHeader = 36 | "HTTP/1.1 200 OK\r\n" 37 | "Content-Type: text/html\r\n" 38 | "Connection: close\r\n" 39 | "\r\n"; 40 | 41 | const char* plainResponseHeader = 42 | "HTTP/1.1 200 OK\r\n" 43 | "Content-Type: text/plain\r\n" 44 | "Connection: close\r\n" 45 | "\r\n"; 46 | 47 | //main web page 48 | char* mainPage = NULL; 49 | 50 | //welcome web page 51 | char* welcomePage = NULL; 52 | 53 | int webPort; 54 | 55 | // Global buffer for storing the Unicode long string (WCHAR array) 56 | #define MAX_BUFFER_SIZE 256 57 | WCHAR g_unicodeBuffer[MAX_BUFFER_SIZE]; 58 | 59 | // Default Unicode string to return on failure (empty string) 60 | WCHAR g_defaultUnicodeString[] = L""; 61 | 62 | // Function to convert ASCII to Unicode long (WCHAR) format using the global buffer. 63 | // Returns: 64 | // Pointer to the converted Unicode string (g_unicodeBuffer) on success. 65 | // Pointer to the default Unicode string (g_defaultUnicodeString) on failure. 66 | WCHAR* AsciiToUnicodeLong(const char* asciiString) { 67 | size_t asciiLength = 0; 68 | 69 | // Check if the input string is NULL 70 | if (asciiString == NULL) { 71 | return g_defaultUnicodeString; 72 | } 73 | 74 | // Calculate the length of the ASCII string safely 75 | while (asciiString[asciiLength] != '\0') { 76 | asciiLength++; 77 | if (asciiLength >= MAX_BUFFER_SIZE) { // Prevent buffer overflow during length calculation 78 | return g_defaultUnicodeString; // String is too long 79 | } 80 | } 81 | 82 | // Check if the ASCII string is too long to fit in the Unicode buffer 83 | if (asciiLength >= MAX_BUFFER_SIZE) { 84 | return g_defaultUnicodeString; // String is too long to convert safely 85 | } 86 | 87 | // Clear the global buffer before use 88 | memset(g_unicodeBuffer, 0, sizeof(WCHAR) * MAX_BUFFER_SIZE); 89 | 90 | // Perform the conversion using MultiByteToWideChar 91 | int result = MultiByteToWideChar(CP_ACP, 0, asciiString, -1, g_unicodeBuffer, (int)MAX_BUFFER_SIZE); 92 | 93 | if (result == 0) { 94 | // Conversion failed. 95 | DWORD error = GetLastError(); 96 | fprintf(stderr, "Error in MultiByteToWideChar: %lu\n", error); 97 | return g_defaultUnicodeString; 98 | } 99 | 100 | return g_unicodeBuffer; // Return pointer to the global buffer 101 | } 102 | 103 | 104 | /** 105 | * Writes formatted text to a buffer, updating the buffer pointer and remaining character count. 106 | * Similar to sprintf, but prevents buffer overflow. 107 | * 108 | * @param buf Pointer to the buffer pointer.
