Random C++ Questions

[cageman]

Thanks! I look into them. I already found GTK myself, but its hard to compare without previous experience with them..

I'd recommend using C# if you need a gui in a language other than AutoIt

It's really easy and intuitive, at least in Visual Studio anyway.

I am thinking about something a lot more complicated. Maybe you could help me out a little bit in the design. I want to create an application that has a lot of calculations (solving mathematical problems). Probably i need to split up the GUI part and calculation part in two separate parts if i want the calculations in C++ and the GUI in C#. Advantage is that the GUI is only depended on some data source and could be quite simple. So you recommend C# for GUI, which i thought was easer, but i thought the problems were also in communication between C++ application and C#.. how would i do it? Database? file as start? I am going to take a big leap by building a multi threaded framework for at least the C++ part. I can use VS2010, so that should be fine yes.

I meant the whole thing, if you needed it to have a gui.

If you wanted to use two different languages, then I'd just create libraries (dlls)

in c++, and the gui in either AutoIt or c#

Ah oke, i will look into that!

How keyboard emulating working? On " Send("{1}") " what kind of function working? Is this Send_input, keyboard_event or SendMessage?

SendInput probably. Though keybd_event uses the same system.

I compiled this into a dll once while trying to learn how to make dlls.

VOID WINAPI Send(char *CharacterString)
{
    char cChar;
    while((cChar=*CharacterString++))
    {
        short vk=VkKeyScan(cChar);                                  // keycode of char

        if((vk>>8)&1)
        {
            keybd_event(VK_LSHIFT,0,0,0);                            // hold shift if necessary
        }   

        keybd_event((unsigned char)vk,0,0,0);                       // key in
        keybd_event((unsigned char)vk,0,KEYEVENTF_KEYUP,0);         // key out

        if((vk>>8)&1)
        {
            keybd_event(VK_LSHIFT,0,KEYEVENTF_KEYUP,0);             // release shift if necessary
        }

    }
    keybd_event(VK_RETURN, 0x0D, KEYEVENTF_EXTENDEDKEY | 0, 0);
}

It basically cycles through a char array and types it in really fast, I use it to spam my friends on steam to be honest.

I used to use an autoit script to count to 10 really fast and pretend to be a hacker, and then I made the little dll to use with autoit and found out that actually doing this~

Func Count()
    For $I = 1 To 1000
        DllCall($hDLL, "none", "Send", "str", $I, "int", 1)
    Next
EndFunc

was just as fast as

Opt("SendKeyDelay", 0)
Func Count2()
    For $I = 1 To 10
        Send($I & "{enter}")
    Next
EndFunc

I was supprised how slow send actually is, and doing it by calling the dll a lot of times was really fast

I guess it's because AutoIt probably checks the string you passed it for a bunch of things like the {} tags and little control characters and has to convert things into proper format, which makes it so slow.

Beside SendKeyDelay there is also SendKeyDownDelay option affecting the speed.

Oh wow, that made a huge difference.

It's seemingly just as fast as that function I posted
