Thread: Help with complex program

I am in need of a program. I am not sure how to program such a thing, so I'll ask for help.

1. I need to make this program calculate the total number of possible combinations of letters and/or numbers in an entered amount of digits. (example: entered 1 digit for numbers only and you get: 10. Enter two digits for numbers only and get: 100. ect.) There must be some sort of formula, but I am not sure what it is.

2. Is is possible with C++ to have this program make the mouse click at specified x,y and to have the program type in text and deleate text? If so, then how would I go about doing this? If no, then what language could accomplish this?

It's generally refered to as a the "decimal number system" or "base 10". "dec" in "decimal" means 10.

Yes I'm sure that works....but what is the formula for adding in letters? (lowercase only)

How many letters are in the alphabet?

Therefore, it must be 36^#of spaces I believe.
Well that parts done...

Now about the auto clicking/typing/deleating.

Ok, so what I am trying to do is:

Create a program which finds out all the possible combinations for the entered number of spaces. Then I want to make it so you can specify an x,y coordinate for the mouse to click, what it types in, and what it deleates. Once that is set up, you enter the time it takes between the click to the time of the next typing (to explain that I want it to type in something, then click at a spot, then deleate what it was typing, and then type another thing, and repeat). Then, the program clicks on the designated places, and types in all of the possible combinations (see beginning) one by one. The program should also have a pause and resume button, so you can pause it whenever you wish (possibly even save your process).

I believe that that should be doable. If you do not understand something fully, feel free to ask.

The second part is operating system dependant. In Microsoft Windows I think you could use WindowFromPoint followed by sending WM_SETTEXT to the returned handle with SendMessage.

does anyone know how i could program this?

It's up to you to make the first move, post what you can achieve and then we help you along the way.

Yeah i guess your right. I'm planning to do everything except clicking, typing and deleating in the next week or so, once i get some free time . I am confident that I can do at least that part.

So, I am starting with the other nessasary things, but I already ran into a problem...

I wrote the code needed to make a window (I believe), but I keep getting an error I can't figure out.
The Error is:

Code:

[Linker error] undefined reference to "GetStockObject@4"
id returned 1 exit status
[Build Error] [windowmenu.exe] Error 1

I use Dev C++ 4.9.9.2

The code is...

Code:

#define WIN32_LEAN_AND_MEAN
#include <windows.h>
#include <windowsx.h>
#include <stdio.h>
#include <math.h>
#define WINDOW_CLASS_NAME "WINCLASS1"
HWND main_window_handle = NULL;

        {

        TranslateMessage(&msg);
        DispatchMessage(&msg);
      }
    }
}

That is the code that my C++ book has in it. If you know of a better way to do make a window, feel free to say so.

Anybody? Please help, I can't figure it out.
