Hooking is about capturing messages that are sent ot other applications. If you want to send a message then you just need to use the SendMessage function[^]. Although you will first need to get the handle to the Window via FindWindow[^].
I used the SendMessage() function many and many times, what it did is only close the handled application!!
I used also, PostMessage() and it did the same!
I used sendInput() and there is no response at all..
that's why I went to hook..
otherwise If there is a reliable way I will not go to hooking at all..
could you help in this please,,
if you need some code i will post, but if you provide me with a reliable code that can really send the mouse event to the application without moving the cursor, I will be thankful for you really
MOUSEEVENTF_MOVE is not a valid Windows message; you are just sending nonsense values.
The debugger message is just telling you that the Handle's value does not point to a valid portion of memory. This is expected since handles are arbitrary values used by the Windows OS.
You need to understand the use of all the windows messages which all have names beginning WM_, and are documented in MSDN. The links I gave you earlier will lead you to some of them. You can also look at the SendInput function[^] which may make it easier to achieve what you want.
Sorry, this site does not provide a service like this. You need to use your debugger to identify where the crash occurs and why. You can then come back here with the details, and people will try to help you.
I'm not sure that this is anything to do with managed C++/CLI, however ...
If you have a problem with some code that you downloaded from the internet, then you need to go back and talk to the person or people who provided it. But something called workingbutcrap is not very inspiring. And if you have issues with an article here on CodeProject then you should use the forum at the end of the article.
I'm facing the following strange problem using MFC Grid Control (by Chris Maunder) in my VS2010 MFC application:
I've included the CGridCtrl control in a dialog in order to let the user to edit data. It works fine but sometime when I open the dialog the cells content is not displayed but it's covered by the cell background color.
Unfortunately I can't solve the problem because it only happens randomly. I tried to call Invalidate() to both the CGridCtrl control and the dialog but it doesn't solve.
I want to save the ASCII characters, in this case i started with the "☺" when someone press alt+1.
I dont know how to save that type of characters in the txt. What can i do?
Ive searched like a month about this, in all kind of forums, asking my teachers or people who knows and nobody can answer me this.
A possible solution was to make all again and use HOOK functions and some others like: WH_KEYBOARD_LL. Well... i dont know how to use any of that functions, so its a big problem.
First of all if you want handle characters that are out of standard printable set, and could be filtered by text handling, open the file as binary:
FILE *txt = fopen("Experimento.txt", "ab+");
In this case you have to manually handle end of line adding "\r\n" at end of each line isteade of the simple "\n", but you are free to store the whole set untouched.
Anyway even using standard text file opening there could be a couple of issues that you have to deal with. Just to be sure that the correct code has been saved in the output file open it in a binary editor and verify that the code 0x01 has been stored in the file, if it is not there you can try to open the file in binary mode, as reported above, or you can use putc instead of fprintf:
But if the file is correct and 0x01 is in but you cannot visualize it the problem is a different one, if you can't show it in a console window or in a text editor the problem is that the ascii code you expect is not in the codepage used on your system. In this case the things get somewhat harder...
I am trying the display the transparent ".png" image on the button it is working fine if i have the proper resource file but the situation is like that i have to get the image from a file and Load it on the button how do i do it please any kindly help me.
This array shows music times: 1 - 1/2 - 1/4 - 1/8 and so on.
I think it should be written by recursive function, because I couldn't do it by while and for loop.
Now, I need all sorted figures that sum of them are equal 1. For example:
1/2 - 1/2
1/2 - 1/4 - 1/4
1/4 - 1/2 - 1/4
1/4 - 1/4 - 1/2
1/4 - 1/4 - 1/4 - 1/4
1/8 - 1/2 - 1/4 - 1/8
1/8 - 1/2 - 1/8 - 1/4
1/8 - 1/2 - 1/8 - 1/8 - 1/8
Of course, number of figures will be too many more if we add 1/16 and 1/32 and ... .
I can print them in a web page(response.write) or in a c console; it's not important. But the algorithm should be as simple as possible.
Thank you all.
