ReadProcessMemory Keeps Returning 0 - Error: INVALID WINDOW HANDLE
Dec 6, 2008I'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]
.net - Regex Replacing Non-words Chars In Strings, Ignoring Specific Chars?
Oct 8, 2011In VB.net I've got the following line that removes all non-alphanumeric chars from a string:
return Regex.Replace(build, "[W]", "")
I now need to extend this to remove non-alphanumeric chars that aren't [] or _. I've changed the line to:
return Regex.Replace(build, "[W[]_]", "")
However I'm pretty sure that this says
replace non-word or [ or ] or _
how do I negate the tests for the [] and _ chars so that it says
replace non-word and not [ and not ] and not _
Some examples:
"[Foo Bar_123456]" => "[FooBar_123456]"
"[Foo Bar_123-456*]" => "[FooBar_123456]"

OpenProcess And ReadProcessMemory?
Oct 4, 2009I'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.

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

View 5 RepliesHowt To Use WriteProcessMemory And ReadProcessMemory
Jun 24, 2009This 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'.
VS 2010 ReadProcessMemory - Can't Read Enough?
Dec 15, 2010I'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.

C# - Implementing An Algorithm To Read A Foreign Process Memory Using OpenProcess And ReadProcessMemory
Aug 26, 2009I'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.

Process.MainModule.FileName: "Only Part Of A ReadProcessMemory Or WriteProcessMemory Request Was Completed"
Jun 1, 2008I 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?
