I would like to know how you can get into a game using the ReadProcessMemory technique. Could someone help me by telling me what information I need to get into the game and the code required.
View 5 RepliesThis time i have to read a string from a textbox on an other window (not one form in my project).I've got the correct address to that string memory, i can always get the correct
handle and process of the window, but i don't know how to use themwith ReadProcessMemory
I am trying to create a graph that changes every second and just shows a 3 second history. In my head it would make sense to tie it into the T variable (Time in seconds), so I have form1 outputting T to a text box on form2 and then everytime that textbox changes it graphs the new chart.
The reason I am doing the step ladder approach is because I wanted the numbers to appear under the points as they travel. does this make any sense at all, or am I completely off base?

1.Converting a wav file to mp3
2.Create a mp3 player by use of a decoder for playing this mp3 file.
I want some help from the best audio programmer who can explain me the decoding logic used to play the mp3 file(Programatically) I am aware of the bit patterns and the data chunks of mp3.I have the knowledge of the data chunks used in mp3 and wav files .I have also used winmm.dll file earlier to ascend into and descend out of the data chunks of wave files.But don't know how the bits are played in a player.Now I need to convert the wav file into mp3 format by use of some encoder program.I came to know about some lame encoder program but am unable to get how to start understanding it's code.
I've been thinking about this problem for a while now and I'm still not sure what is the best approach.Basically I've got several hundred email addresses stored in a Database, and every week I would like to automatically send these addresses a bulletin of information. I've accomplished this with a Stored Procedure and a Scheduled Job on the DB (Oracle), but I'm sure this could be achieved better with some VB.net solution.I've read about people writing a Windows Service, or creating a Console Application and using Windows scheduler. I'm swaying to wards the Windows Service approach but I'm not sure how to tell the service to send emails at a specific time every week. Any ideas, or is there a better approach?Also, what would be best? Send individual emails to the addresses in the emailing list, or send one email with every address added as a BCC?
View 2 RepliesI know this is a VB.Net messageboard, but it can work with in all languages. Is there a quick way to complete a line (sample code):
//Setting variables set 1
a = e;
b = f;
c = g;
d = h;
.....
//Saving changes set 2
e = a;
f = b;
g = c;
h = d;
without having to type everything out...A technique using EXCEL or Notepad....Find and Replace. This would save a lot of time coding and becomes pain in the butt when you working with many variables.
I've been banging my head at a wall for like 4 hours now, googling and searching forums but I haven't found a solution yet. This is (a part) of the code: Public Declare Function OpenProcess Lib "Kernel32.dll" (ByVal dwDesiredAccess As Integer, ByVal bInheritHandle as Integer, ByVal dwProcId As Integer) As Integer
Public Declare Function ReadProcessMemory Lib "Kernel32.dll" (ByVal hProcess as IntPtr, ByVal lpBaseAddress As Integer, ByVal lpBuffer() As Byte, ByVal Size As Integer, ByRef BytesWritten As Integer) As String

i wrote a programm that reads the memory of a program.it worked at xp and vista but not at windows 7 i builded it with microsoft visual basic 2008 express edition.the code looks like this:
Public Declare Function GetWindowThreadProcessId Lib "User32" (ByVal hwnd As Integer, ByRef lpdwProcessId As Integer) As Integer Public Declare Function OpenProcess Lib "kernel32" (ByVal dwDesiredAccess As Integer, ByVal bInheritHandle As Integer, ByVal dwProcessId As Integer) As Integer Public Declare Function ReadProcessMemory Lib "kernel32" Alias "ReadProcessMemory" (ByVal hProcess As Integer, ByVal lpBaseAddress As Integer, ByRef lpBuffer As Integer, ByVal nSize As Integer, ByRef lpNumberOfBytesWritten As Integer) As Integer
[Code]...
This is again something work in VBA while VB2008 not working..I was about to use them to read lines from a listview of an external application...I define them as:
Private Declare Function WriteProcessMemory Lib "kernel32 " (ByVal hProcess As Int32, ByVal lpBaseAddress As Int32, ByRef lpBuffer As IntPtr, ByVal nSize As Int32, ByVal lpNumberOfBytesWritten As Int32) As Int32
Private Declare Function ReadProcessMemory Lib "kernel32 " (ByVal hProcess As Int32, ByVal lpBaseAddress As Int32, ByRef lpBuffer As IntPtr, ByVal nSize As Int32, ByVal lpNumberOfBytesWritten As Int32) As Int32
Originally, lpBuffer was defined as Any, while VB2008 not supporting it, so I make them IntPtr, then I got trouble when I use them..I declare a structure LV_ITEMA then dim myItem as new LV_ITEMA, so when I write:
WriteProcessMemory(pHandle, pMyItemMemory, myItem, Len(myItem), 0)
The program will give an error saying .. Error 1 Value of type 'WindowsApplication1.Module1.LV_ITEMA' cannot be converted to 'System.IntPtr'.
let me show you my code first and then explain my problem.

I've been using the readprocessmemory function to read some values from another program and it works just fine for small values. However when I'm trying to read something like 5000.123456789 or whatever it doesn't even display the 5000, it just displays something that seems kinda random. Now, I've had this problem before and it helped to just increase the iSize from 1 to 10, but now I can't increase it anymore for some reason. I tried to increase it to 100 but then I got a fatal error. Is there some way to get around this? I guess it could also be because I'm not trying to read an integer but a float, but there is no float in VB, so i tried double, but no go.

I'm currently developing a little hobby project to display health information in a game on my G15 keyboard through VB.NET. When I use ReadProcessMemory via an API call, it keeps returning zero. The MSDN documentation referred me to use the Marshal.GetLastWin32Error() call to find out what is wrong and it returns 1400: INVALID WINDOW HANDLE.
I am now confused about whether the first argument of the function wants a window handle or a process id. Regardless, I have tried both with FindWindow and hardcoding the process id while the application is running (getting it from task manager). I have tried three different games, Urban Terror, Grand Theft Auto: SA and 3D pinball for windows, getting the memory addresses from an application called Cheat Engine; they all seem to fail. [Code]
I'm having some problems implementing an algorithm to read a foreign process' memory. Here is the main code:
[Code]...
Although generally it seems to work correctly, the problem is that for some memory values ReadProcessMemory is returning false, and GetLastError is returning 299. From what I've googled, it seems to happen on vista because some params of OpenProcess were updated. Anyone knows what this is about? And what values should I try? Notice that as they changed, I wouldn't want to know if it's VM_READ or so, I want to know exactly what the values are.

I have searched google with this error in relation to Process.MainModule.FileName however none link with the error message, "Only part of a ReadProcessMemory or WriteProcessMemory request was completed".There however was one thread on these forums suggest a 64 bit issue however that was soon excluded as it was reported also in a 32 bit enviroment. The marked answer to that thread suggested it is a security problem however I don't think anything has been changed in relation to that comapred to a 'clean' project.
"If it is a security problem, you may try to run your application under the debugger" Process.MainModule failure I am in-fact debugging this application through Visual Studio so I am not quite sure what to do next in the process of diagnosing this problem. I am debugging using 32 bit in a 64 bit enviroment because of DirectX compatability issues?
im trying to make a game in visual basic in which your character can move around, jump, and kill things. I can get the picture box with the character to move and everything is fine. but i did run into one problem. when the character moves over a tree (or something) you can see the gray backround of the character as i made in paint. how do i make the backround of the picturebox transparent?

I am working on a poker game and I have the game setup the way I want it in terms of graphics and I have the code programed to deal the cards out exactly how I want them. Granted, the code is very simplistic, but functional for a new programmer like myself. I'm sure there are other more efficient ways to code my game, but I like mine so far because I can at least understand the majority of it. With that being said, here are a few problems and questions that I have.
1. How come when all 12 cards are dealt out I have some cards repeating in the game? For example, I get queen of diamonds in more than one picture box when I only want the card to be dealt once and then removed until the next game.
2. I was hoping to have a button 3 to clear all the boxes, basically resetting the game to the next game. When I hit button 3 it only clears the contents of picturebox 10 and 12.Other notes: I have the deal down the way I want it. It deals the first 10 picture boxes and a second button deals the 11 and 12 picture boxes.
3. I know this is my next step so I want to post it with the code I currently have. I want to start taking my project one step further by evalutating each of the three rows of cards (3 rows of 3 cards each - I'm not worried about the dealers hand (picture box 10, 11, 12 yet). So I want to evaluate a row of pictureboxes against a "pay scale" and display the win in a text box or label next to the 3 card hand. For example, Q of diamonds, Q of Clubs, Q of spades would win 15, etc. ( have a weird feeling I may have to change the names of the cards (I have them named card1, card2, etc. right now) to something that identifies them in order to evaluate the hands.
Here is the code that I currently have. I'm using visual basic.

I have created a scrabble game that generates random letters. For the user to type in a word using the random letters they have to type it in a text box.

I'm trying to make a simple fruit machine game for windows mobile device.
I can create the game easily enough and flip through pictures in a picture box to display the correct symbol.. but what I'd like to do is do a proper spinning reel, but have no idea where to even start.
What I have is a list of images in an imagelist (or individual files) - what I'd like is them attached to each other and moving downwards, preferably as though it were going around a drum but just them moving would be a start.
I am trying to make a game which basiclly lets you shoot ducks. i have a picture as a background (set as form image) i then have picturebox's with ducks flying flying around you shoot them the disapear etc.
My problem is the image. i have a picture of a duck and a blue square round it. and i would liketo make it transparant because birds dont fly with blue squares.

Upon changing the field size a game should restart. Upon trying to do so I see the previous grid (e.g. 10x10) displayed on top of the new one (e.g. 4x4). How would I prevent this and indeed start the game fresh?
View 10 RepliesSo here is my problem. I have a vb game with animated sprites and all, and the character even jumps. However it only works in the y direction.

I currently have a who wants to be a millionaire game that I have made in visual basic 2010. Each question is in its own form. Form1 opens at the start, and question 1 is opened by a button click on Form1. The user has to click on the picture box at the side to show the text for the question each time. If they answer incorrectly, it displays a message box, opens an input box asking for their name, and goes to the form with the high score list, Form17.
Upon opening Form17, I want the scores to load and be displayed in the list box. The high scores are saved in a text file at C: est.txt . Upon clicking menu or end, the high scores are saved to the text file.
