VS 2010 ReadProcessMemory - Can't Read Enough?
Dec 15, 2010
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 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'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

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'.

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 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?

I currently have a function that loads an XML and takes all of the nodes and makes an object with them and adds them to an array.I need to be able to now see if there are more than one xml doc in a folder, and if so also add their objects to the array until all of them have been read. How would I go about doing this? I've been searching through the System.IO. to see if I could find something but I haven't been able to yet.

I need to read lines from file. Now my code is like this:
Sub data()
Dim reader As New IO.StreamReader("log.txt")
For i = 0 To 1500
date(i) = reader.ReadLine
Next i
End Sub
Now if some user will change add or remove the data from this file, it will end up with error or sth. I also tried to write sth like this:
Open "C:in.txt" For Input As intInFile
But there appears an error, that open is not declared and IO functionality is microsoft.visualbasic namespace. I added this name space (at the top: Imports Microsoft.VisualBasic), but this error still occurs.

I was taking code called from an event and making a function of it
Public Function asyncPostMS(prefixes() As String, ms As MemoryStream) As Stream
Dim request As WebRequest = WebRequest.Create(prefixes(0))
request.Method = "POST"
[Code]....
Now when I call this using the new function the stream is already closed. How do I pass out a stream object from a function as an already "read" object.
Or do I need to create the stream outside the function?

I have an excel database with one column and thousands of rows of "number" data. I need to import the data into my form read the first entry, run an algorithm then move the result to the second column then move to the second entry and so on. I am having issues with where to begin. I am able to convert the excel database to a text file if it makes it easier.The algorithm that needs to be ran consists of reading each character one at a time and is as follows:ENTRY example: 12358458754The characters 1,3,8,5,7,4 need to be summed then multiplied by 3. These are all the characters starting with the first one and skipping every other one. I will call them "odds" (not referring to numeric value)The characters that are skipped, I will call them "evens", need to be summed together then added to the result of "odds".

I am making a recipe book that calculates the amounts of each ingredient needed for a dinner.The user inputs the number of people they are cooking for and then my program works out the amounts of ingredients needed, simply by * number of people.I know how to read from text files using commands such as: My.Computer.FileSystem.ReadAllText()But does anyone know how to take text for a text file, then multiply the contents of that file by the number of people?The text file only stores numbers, but I want to multiply each line seperately..Instead if getting the result of 10050*3, I want 100*3 and 50*3 on a seperate line.[code]For this to work, I suggest downloading the full project.You will also need to create a folder with two text files inside it. This will not work without them. "QuantityList.txt" and "IngredientList.txt".

My question is a rather simple one and to be honest with you, I am not sure if it can be done. Lets say I have a mutli-line text box, is it possible, and if so how would I go about making it so if I clicked Open with > editor I could do things with this text, such as TextBox.text = [file contents]. If it's not possible just let me know and I'll stick with open file dialogs.
