I want to use the code from Ted Burke.
(Refer to <http://batchloaf.wordpress.com/2013/02/13/sending-a-key-to-a-window-thats-not-in-focus-c-program>)
Compiler creates following errors:
POLINK: error: Unresolved external symbol '__imp__FindWindowExA@16'.
POLINK: error: Unresolved external symbol '__imp__GetWindowTextA@12'.
POLINK: error: Unresolved external symbol '__imp__SetForegroundWindow@4'.
POLINK: error: Unresolved external symbol '__imp__SendInput@12'.
POLINK: fatal error: 4 unresolved external(s).
*** Fehlercode: 1 ***
Subsystem type is : console
Any help is appreciated.
Here is Ted's code:
#define WINVER 0x0500
#include <windows.h>
#include <stdio.h>
int main(int argc, char *argv[])
{
// Check number of command line arguments
if (argc < 3)
{
fprintf(stderr, "Too few command line arguments\n");
fprintf(stderr, "Usage: sendkey.exe KEY_TO_SEND");
fprintf(stderr, " WORD_FROM_TARGET_WINDOW_TITLE\n");
return 1;
}
// Get the character to send from the first command
// line argument
char char_to_send = toupper(argv[1][0]);
// Get first window on desktop
HWND firstwindow = FindWindowEx(NULL, NULL, NULL, NULL);
HWND window = firstwindow;
TCHAR windowtext[MAX_PATH];
// We need to get the console title in case we
// accidentally match the search word with it
// instead of the intended target window.
TCHAR consoletitle[MAX_PATH];
GetConsoleTitle(consoletitle, MAX_PATH);
while(1)
{
fprintf(stderr, ".");
// Check window title for a match
GetWindowText(window, windowtext, MAX_PATH);
if (strstr(windowtext, argv[2]) != NULL &&
strcmp(windowtext, consoletitle) != 0) break;
// Get next window
window = FindWindowEx(NULL, window, NULL, NULL);
if (window == NULL || window == firstwindow)
{
fprintf(stderr, "Window not found\n");
return 1;
}
}
fprintf(stderr, "Window found: %s\n", windowtext);
// Bring specified window into focus
SetForegroundWindow(window);
// Create the desired keyboard event
INPUT ip;
ip.type = INPUT_KEYBOARD;
ip.ki.wVk = char_to_send;
ip.ki.wScan = 0;
ip.ki.dwFlags = 0;
ip.ki.time = 0;
ip.ki.dwExtraInfo = 0;
// Send the keyboard event to the specified window
SendInput(1, &ip, sizeof(INPUT));
}
