I'm trying to read another process's memory starting from mbi.BaseAddress to mbi.RegionSize using the function ReadProcessMemory, however I only succedeed to read 1 address at a time and it takes like forever to finish, the result being stored into a byte() variable, calling the readaddressmemory 1 million times instead of only 1 for example.

Read/Write Process Memory?
View 6 Repliesi have tryed so many times now so is there some one that can Read/ Process Memory in vb.net 08 ?
this is what i got
Dim help2 As Integer
Dim HP_Have As Integer = &H574
Label5.Text = ReadProcessMemory(proc.Handle.ToInt32(), HP_Have, help2, 4, 4)
I need a code that search's in a process memory a custom value. And get the address of that value. Its a simple question but with a hard answer. I've searched in all over the internet, but couldnt find any.
View 6 RepliesIve basically got 2 problems I need to solve.1) I am trying to determine if a certain process is running on the user's machine at the same time as my program.2) I am also then,if the process is running, trying to edit a specific memory addresses value. I have already found the memory addresses for the program, but how do I tell VB.Net to basically read the current value stored in that memory address, and then write a new value to that address
View 1 RepliesI want to be able to read and write the process memory of Firefox for a game on facebook(It's kind of like cheating only you can't cheat, nothing stays permanent.) this is just for fun. The game is called happy fish aquarium and you raise fish in the game and it's just really addicting. I found a program that reads process memory and lets me change certain values in happy fish aquarium so I can make my fish tank look different or whatever. But if I reload the page it will of course go back to the original state because the fish tank's memory is held online. The point is, I just want to make a program that can read the process memory from Firefox from a certain range and bytes. like 4 bytes and a range of 00400000 to 7FFFFFFF. Does anyone know how I can achieve this? Please note, this is not for cheating purposes in any way whatsoever, it's simply for visual fun(visual meaning only I can see it). What I want to do is the same as using the add-on firebug in firefox to change the html on a webpage.
View 10 RepliesI'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.

Whats happening is I run the code below and get the following error "The system cannot find the file specified". I've read that with UseShellExecute set to false that you can't use WorkingDirectory.

Im getting a problem with one of my programs I have made in visual basic.NET where it gives me a memory error when i debug the program in the IDE. the exact error is this: "Attempted to read or write protected memory. This is often an indication that other memory is corrupt". My program basically has a few forms with text fields on that get their text values from an access database on the same hard drive. Im wondering if im doing something wrong because my program just seems to eat up memory whenever it does anything. For example I have one form that has a combobox on it and when you change the drop down list selection it retreives a few strings from the database and puts them into the relevant text boxes, if you keep changing the selection then the memory usage (in task manager) just keeps going up and up. occasionally I get the error mentioned above when debugging but in my built version of the program it throws an exception everytime the memory usage gets past 49K.
Also I noticed when debugging in the "immediate window" frame I get the following message often:A first chance exception of type 'System. Invalid OperationException' occurred in System.Data.dll...Do I need to somehow be "releasing" the memory that is used to gather data once it becomes redundant?
I am using the following code
This error occurs :

I cannot use Visual Basic 2008 at all. When I go to "new project" and choose "Windows Form Application" I get this error.I have tried multiple uninstall/reinstall with no result.A microsoft reply to this suggested that I needed: " .NET Framework 2.0 Service Pack 1 " I checked, and I did not have the .netframework 2.0 service Pack 1.
When I tried to download and install the above from Microsoft.com, the istaller said that "it was not allowsed" and I was not able to install the service pack 1.
I tried Uninstalling net framework 3.5, 3.0, 2.0 and then reinstalling .netframework 2.0 sevice pack 1; then reinstalling Visual basic 2008 express edition. At the reinstall of Visual basic 2008, .netframework 2.0 sevice pack 1 is unistalled by .net framework service pack 2.When I check the foruims for simiar problems, the formus are mostly for Visual basic 5.0, or other programs that I do not have.
Here is the programs I have installed:
Operating system: Windows XP
Microsoft .net framework 1.1
Microsoft .NET framwork 1.1 Hotfix(KB928366)

I have two forms, Form1 and Form2. Form2 has a button to show OpenFileDialog. I call Form2 from Form1 by a button. My startUp Form is Form1. When i start debugging, i press my Form1's button to show my Form2, it shows, but when i click On Form2's Button to show OpenFileDialog it is giving me exception that
"Attempted to read or write protected memory. This is often an indication that other memory is corrupt."
When i set my startup Form to Form2 and click Form2's Button to show OpenFileDialog then it shows!
I'm trying to execute a 3rd party application, called from a .cmd batch file, called from a self-hosted WCF service. Like this:
WCF --> .cmd --> 3rd party app
For whatever reason, using the Shell command doesn't work fully. It will call the .cmd file, but the 3rd party app won't kick off (I know the .cmd is firing because I have before/after ECHO statements populating a log file). If I double-click the .cmd file from explorer, the 3rd party app will start just fine. So, I figured, maybe try something besides the Shell command from my WCF service.
So I tried the following code, but it won't kick off the .cmd file at all (echo statements not firing). What am I missing here?
Dim psi As New ProcessStartInfo("cmd.exe", "/C " & System.Configuration.ConfigurationManager.AppSettings("ExStream_CMD_File_Path"))
Dim proc As New Process()
proc.StartInfo = psi
proc.Start()
proc.WaitForExit()
The path in the app.config file is valid (just double-checked). Is there anything wrong with the above code?

I have a user interface with pushbuttons, each starting a different process. Can I manage these pushbuttons via usb numpad? i.e. if 1 is pressed at numpad, pushbutton 1 will be clicked (so process 1 will start); if 2 is pressed at numpad pushbutton is 2 will be clicked and so on.

View 1 RepliesI'm using an electronic signature pad for one of my applications. The pad has a Control Panel file which handles it's configuration (image display, etc). I would like to know if it is possible to open the pad's control panel from within VB.NET. I've tried using Process.Start() but can't get it to wok, and I'm not sure if it is a problem with what I'm typing in, or if Process.Start is not what I need to use here.
View 5 RepliesI am writing an application which needs to allow the user to select and open document files as a new process, edit them, then when they've finished backup the changed files automatically. For example, start a .doc file within Word or a .xls file with Excel What I wanted to do was use process.start to run the application and store the ProcessID returned in an array so that when the process finished, I could check all the files that were using that application for changes.

I want to launch System Restore through my program. I figured out the destination of this feature in Win7 is: WindowsSystem32control.exe sysdm.cpl @0,4
So I wrote this
Dim p As New System.Diagnostics.Process
Private Sub CreateASystemRestorePointToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles
[Code]....
Problem is that it will not work if I have anything behind .exe And "sysdm.cpl @0,4" is vital for this to work, otherwise I just launch Control Panel, which is pretty useless for what I want to achieve.
So how do I include commands like those in Visual Basic?

View 7 RepliesI have this in a VB.NET console application:
Dim p As ProcessStartInfo
p = New ProcessStartInfo(Environment.CurrentDirectory & "injavac.exe",ClassName & ".java")
Dim ps As Process = Process.Start(p)
This does run the java compiler on the file, but it does so in a new window. I want the output from javac to appear in the same console that is running my application. How can I do this? Perhaps there is another method for running commands in the current console? Or maybe I can supress the second console window from opening and redirect its output to the current console?

I have an application that starts one of two external CAD applications depending upon the extension of a file in a ListView. I have been able to start up the application to view the file selected without a problem. I also have a seperate print click event for printing the file that opens the viewer application in the background and prints the file. This works perfectly for one of the CAD viewers but when I select a file that requires the other viewer application to print I get a Win32 exception and an error message stating that the file is not associated with any application and it cannot be opened. This of course is rediculous as it opens fine in the "View File" click event that opens the viewer to check the drawing.
One rather strange observation is that the CAD viewer that does print the associated file will launch the other CAD viewer application (that is associated with the other file extensions) when the "View" click event is handled even though I had not incuded the code to execute the process to start the viewer for that type of file. I realize this rather convoluted and may lie in the ProcessStartInfo arguments that I pass to the application.
Here's a code snippet:
Private Sub PrintFinGoods_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PrintFinGoods.Click
Dim message As String = "No application is associated with file"
