SendInput() and MOUSEINPUT Problems

[Madhu_Rani]

INPUT myInput; myInput.type = INPUT_MOUSE; MOUSEINPUT mouseInput; mouseInput.dwFlags = MOUSEEVENTF_MOVE|MOUSEEVENTF_ABSOLUTE; mouseInput.dx = 0; mouseInput.dy = 690; mouseInput.mouseData = 0; mouseInput.time = 0; mouseInput.dwExtraInfo = NULL; myInput.mi = mouseInput; SendInput(1, &myInput, sizeof(INPUT)); PROBLEM 1: The mouse is moved at the upper-left corner while through this code, I am requesting :laugh: him to move to BOTTOM-LEFT corner? Why this is not happening. PROBLEM 2: I want to send event MOUSEEVENTF_RIGHTDOWN ( right button pressed at BOTTOM-LEFT), and request the system that please feel like as I click you at start button :( , but it is not accepting my command, I changed the flag to mouseInput.dwFlags=MOUSEEVENTF_RIGHTDOWN|MOUSEEVENTF_ABSOLUTE; So What is wrong ?

did u called SetCursorPos to set the cursor to that possition before sending the mouse input?

VOW you are GENIOUS. THANKS. Now I also find the solution of problem2 that I pasted below. Actually in none of the article that are related with the SendInput , anyone talked about SetCursorPos. I guess it is good to call SetCursorPos first and then use the SendInput() function. 1- First Call SetCurPos() 2- then Call the SendInput() to perform the mouse events like button down up etc. INPUT rightClick[2]; MOUSEINPUT rightDown; rightDown.dwFlags = MOUSEEVENTF_RIGHTDOWN + MOUSEEVENTF_ABSOLUTE; rightDown.dx = 0; rightDown.dy = 0; rightDown.time = 0; rightDown.mouseData = 0; MOUSEINPUT rightUp; rightUp.dwFlags = MOUSEEVENTF_RIGHTUP + MOUSEEVENTF_ABSOLUTE; rightUp.dx = 0; rightUp.dy = 0; rightUp.time = 0; rightUp.mouseData = 0; rightClick[0].type = INPUT_MOUSE; rightClick[0].mi = rightDown; rightClick[1].type = INPUT_MOUSE; rightClick[1].mi = rightUp; // finally, send the spoofed right-click to invoke the menu ::SendInput( 2, rightClick, sizeof(rightClick[0]));

Another Problem: The logic of SetCurPos()works for the right clicks and OS take the appropriate action against the right click, but it did not work for left click. When I changed both flags to MOUSEEVENTF_ LEFTDOWN in the code. The cursor goes at the bottom-left corner but application can not trigger the start button (Window Start) event, as cursor was at that point. Actually if the cursor is at the button, then we require to have a left click at button? so how we manage a click at a button by using sendinput() method. SetCursorPos(10,790); INPUT rightClick[2]; MOUSEINPUT rightDown; rightDown.dwFlags = MOUSEEVENTF_RIGHTDOWN + MOUSEEVENTF_ABSOLUTE; rightDown.dx = 0; rightDown.dy = 0; rightDown.time = 0; rightDown.mouseData = 0; MOUSEINPUT rightUp; rightUp.dwFlags = MOUSEEVENTF_RIGHTUP + MOUSEEVENTF_ABSOLUTE; rightUp.dx = 0; rightUp.dy = 0; rightUp.time = 0; rightUp.mouseData = 0; rightClick[0].type = INPUT_MOUSE; rightClick[0].mi = rightDown; rightClick[1].type = INPUT_MOUSE; rightClick[1].mi = rightUp; // finally, send the spoofed right-click to invoke the menu ::SendInput( 2, rightClick, sizeof(rightClick[0]));

void GenerateKey(int vk , BOOL bExtended) { KEYBDINPUT kb = {0}; INPUT Input = {0}; // generate down if(bExtended) kb.dwFlags = KEYEVENTF_EXTENDEDKEY; kb.wVk = vk; Input.type = INPUT_KEYBOARD; Input.ki = kb; ::SendInput(1, &Input, sizeof(Input)); // generate up ::ZeroMemory(&kb, sizeof(KEYBDINPUT)); ::ZeroMemory(&Input, sizeof(INPUT)); kb.dwFlags = KEYEVENTF_KEYUP; if(bExtended) kb.dwFlags |= KEYEVENTF_EXTENDEDKEY; kb.wVk = vk; Input.type = INPUT_KEYBOARD; Input.ki = kb; ::SendInput(1, &Input, sizeof(Input)); } check this

Thanks. Though it is not a recomended method but I called the SendInput function twice and now it works:) ::SendInput( 2, leftClick, sizeof(leftClick[0])); ::SendInput( 2, leftClick, sizeof(leftClick[0]));

[Adam Roderick J]

good, Just check by chaning the Time stamp for the event.

I think the operative word is normalized. Notice the range for dx and dy is from 0 to 65535, regardless of monitor resolution. The MOUSEINPUT structure is not necessary as the INPUT structure already has one, like:

INPUT myInput;
myInput.type = INPUT_MOUSE;
myInput.mi.dwFlags = MOUSEEVENTF_MOVE | MOUSEEVENTF_ABSOLUTE;
myInput.mi.dx = 0;
myInput.mi.dy = 690;
myInput.mi.mouseData = 0;
myInput.mi.time = 0;
myInput.mi.dwExtraInfo = NULL;
