I created this class to facilitate some routine tasks when modding or hooking software. If you dont know what hooking is or how to use .dll’s it is of no use to your. It also bridges the gap between oop and asm a little, I try to give you the best of asm in a oop format.
Features
In a Nutshell
This class does all the work for you, just create the project and pass a function into the constructor and it will take care of the threading. The function you pass to it is the main function of the thread that is started, in this function you can handle key input or whatever manipulations you wish.
How to use
This is for use with Visual Studio, as I use masm syntax in the inline asm. Basically you make a VS c++ project of “.dll” type, then you include modtoolz.h class. If you dont know how to do that, just stop now. If you want a in depth “noob” tutorial, I wrote one here.
add these to your stdafx.h
#include <stdio.h>
#include <iostream>
#include <io.h>
#include <stdio.h>
#include <fstream>
using namespace std;
Everything happens when you call the constructor (as it should with oop). So in your main.cpp you could call the constructor like this
#include ModTools.h
// other stuff
// modtools constructor one
ModTools mt("window name", &myEngine);
If you did it like that you would have to have a function “myFunction” that you could handle events and keys. The function you pass into it with this constructor gets started in the thread, so when that function terminates, so does the thread. You need a while loop and some stuff like so
1 2 3 4 5 6 7 8 9 10 | long WINAPI myEngine(long lparam) { while(1){ // this goes forever, so your thread stays alive Sleep(10); // ~10 millisecond delay so it dont lag // if they hit f12 turn on the console if(GetAsyncKeyState(VK_F12) == -32767) { mt.Console(); } }// end the while loop |
that function would toggle the console on/off with the press of F12. Of course you could make it do any action based on any keys, for instance call a function inside the program, or change a memory value inside the program. Since you are inside the program in your .dll you can change anything or call the programs functions.
The above method is easy and does work fine; however, there is another constructor that you can also use which is more efficent. The second constructor (that you can use) hooks directly into the window, this allows you to handle key input better.
You can use the second constructor like so
1 2 3 | #include ModTools.h // second constructor ModTools mt("brood war", &KeyHandler); |
In this case you can only pass it a keyhandler, anything that takes time to process that is in this “keyhandler” function will lag the target application instantly. If you wish to do heavy processing and queues and such either make a new thread or jmpPatch to another function in your code.
Anyway this is what a keyhandler function looks like
1 2 3 4 5 6 7 8 9 | bool KeyHandler(int keyCode) { // Is key ~ pressed? if (keyCode == VK_OEM_3) { // DO SOMETHING } return FALSE; } |
This second constructor is more advanced and I do not recommend you use it unless you know what you are doing. That said, the second constructor is the way to go if you want to make really good applications.
If you are still confused I made a tutorial on another site that is pretty informational. You can acess that here. In that tut I show how to use the modtools.h class to do stuff with the game starcraft.
You can download modtools.h here modtools-v02

MSI GPS Receiver
I dont have built in gps in my HTC 8525, so I ordered this to connect with my phone. On ebay it cost me about $50 with shipping.
It has proven to be very versatile. It connects to the satellites quickly and works in the car. I have had it in places where my cell does not even work and it works, granted not in 3d but it worked in 2d.
About the mini usb port
Unless you have a bluetooth on your computer there is no connectivity. The mini usb port is for charging, but it also transmits the GPS information through uart via the usb port. So if you want to connect this GPS module to a microchip it works great.
Pins one and four are power and ground respectively. Pins 2 and 3 are rx and tx @ uart levels. It transmits at 38,400 baud on the mini usb , which is much faster than the 4,800 baud via bluetooth.
I for one would rather have it this way, I can just get a $5 bluetooth for the computer if i want to communicate via bluetooth. This uart communication hidden in the mini usb allows for much more versatility and customization.You can connect it to a MCU, or you can connect it to a MAX232 converter and then to the serial port. I should also add it is easy to develop your own applications to process the gps data.
NMEA
The protocol that GPS devices use is called NMEA, it looks like this
$GPGGA,023530.379,2917.1882,N,09448.0603,W,0,00,,47.5,M,-23.9,M,,0000*72
$GPGSA,A,1,,,,,,,,,,,,,,,*1E
$GPGSV,3,1,10,14,54,009,,31,65,209,,22,57,100,,30,28,092,*7C
$GPGSV,3,2,10,18,24,117,24,05,20,065,,11,14,305,,12,12,055,*70
$GPGSV,3,3,10,32,12,312,,19,00,254,*71
$GPRMC,023530.379,V,2917.1882,N,09448.0603,W,,,190109,,,N*64
This information tells you all about your location, the time, your speed and the satellites you have connected to. I’m not going to explain it all here, but here is a pdf explaining NMEA. nmea0183
Conclustion
While this device was a little pricey, it proved to be a great addition to my electronics. It works great with programs like IGO to make sure I never get lost.
Ok i know your saying to yourself “theres already tons of these” but i looked at them and they are long. Anyway i made this to test my ports. Very simple a led connected to port “B” and port “D” on a 877. I know there are better ways to make a led chaser using less pins but im testing my ports (new board) so i need to have a light on each pin to see if it works correctly, im making like a prototyping board and i want to know that all the connections/pins are solid before i make anything out of it.
The best part about this is “bit shifting”, no case/switches or any of that crap. This is the while loop just put it in your main and modify it for your application. It speeds up and slows down, thats what the delay increment is for. before you get into the while loop. If for some reason your using a port that has more than 8 pins you wont be able to store the “bit” variable in a int, try like a int16 etc.
int i =0;
int bit = 0;
int delay = 0;
while(1)
{
if (delay > 50){delay = 0;} // if the delay is getting big make it small again so it goes fast
bit = 1; // set the bit to the rightmost position (pin 1)
for(i=0;i<8;i++)
{
output_d(bit << i); // shift bit to the left "i" times
output_b(bit << i);
delay_ms(delay);
}
bit = 0b10000000; // put the bit on the far left (pin 
for(i=0;i<8;i++)
{
output_d(bit >> i); // shift the bit to the right "i" times
output_b(bit >> i);
delay_ms(delay);
}
delay++; // increment the delay so it goes slower
}
There were requests for a picture … this was all i could find, it gives you a idea how the display might have been hooked up
3 digit 7 seg display
This was for our intro to engineering project It is a thermometer with a lm34 connected to ra0. It multiplexed 3 “7Segment” led displays connected to the ports, i think the digit was port E and the 7 led’s of the “7Segment” displays were connected to B. You can easily use it on a 877a also if you include the .h for the 877a . I will try and post the schematic but it was all pretty much done on the fly, a schematic was only made for half of it.
It has a lot of functions to do stupid stuff, you dont need them. Any questions post a reply. I would not use this code because i doubt you will have the same setup but it would be a great reference.

doneMy first attempt at reproducing a rts in flash. There is a lot to it, you have to calculate the speed and angle of everything. In this one I replaced the cursor, but you can see the probes dont look quite right.
Made this a while back, its not very efficient but it looks neat
made this for testing my web server that is on 24/7, turns out it only cost me about $10 max to run it all month.
