IDE :: Out Of Virtual Memory While Writing (not Debugging)
Jun 15, 2009
I'm editing some code and moving stuff around doing a lot of cut'n'paste while writing and the intelli-sense slows to a grinding stall then eventually I get a message from my OS saying that I'm low on Virtual Memory and I haven't even run the compiler yet, still only in the IDE. ??? I 'unchecked' the 'enable Visual Studio hosting process' on the properties->Debug tab when this happened before and now I don't know what to do because VB won't run at all for more than half an hour making writing impossible...
I have created a WFA that has 5 projects in it. One of the projects runs against 600 + servers and queries each server for local administrator accounts and then dumps that into an excel file. It will also check to see if the account that is in a local administrator group is disabled in AD. The problem that I have is that when I run the particular project I will run out of virtual memory. I have 4 gig on my computer. Is there a way to control this?[code]...
I still have one more problem getting total/available virtual memory. Code: Select Case My.Computer.Info.TotalVirtualMemory Case Is >= 1073741824 GetRAMInfo += FormatNumber(My.Computer.Info.TotalVirtualMemory / 1073741824, 0) + " GB" + vbNewLine Case 1048576 To 1073741823 [Code] .....
For example, now Windows System Information returns: Total Virtual Memory = 15.8 GB Available Virtual Memory = 5.52 GB While the above code returns: Virtual Memory: 8,191 GB free of 8,192 GB (I also use the same above code for My.Computer.Info.AvailableVirtualMemory)
Any right direction for best practices of memory allocation. (i.e., disposing of forms, setting variables to nothing). I am writing a program and for now, I just monitor it in Task Manager. I notice that the size change isn't very balanced. The amount of memory used when a new form loads isn't as much as when that same form is closed. (either by button or by the 'x'). I want to get a handle on this before I get too deep in the program.
I'm running VB2008 on Windows 7; I've written out a ver simple piece of code:
Option Explicit On Module

When I run or debug the code, it asks for the First Number and then just completes the running of the program without asking for the second number and uses some random number. The console.readline() doesn't work either, the console window just disappears.
Im having trouble writing different values types to memory, for a particular exe Using the code below will allow me to write a value of 4 Bytes correctly but I also need to write a Float value.[code]Is there any way I can have both of these, to allow me to write 4 byte integers as well as Float Values?
I am using these API functions for my project where I am handling 3 unmanaged DLLs of two external apps, basically all it does is to carry data back and forth between these external applications. The project needs a lot of use of pointers, passing pointers and reading/writing to memory so both applications can talk to each other.
Declare Function HeapAlloc Lib "kernel32.dll" _ (ByVal hHeap As Long, ByVal dwFlags As Long, ByVal dwBytes As Long) As Long Declare Function HeapCreate Lib "kernel32.dll" _
[code]....
set of windows API functions for allocating memory, reading and writing to allocated memory, and other required functions to generate required arguments to pass to these API calls?I am up to where I am allocating memory and getting pointer, but I don't know how to go about reading, writing, passing pointers, finding data lengths and reusing memory.
I've made a screen capture program, and I have a program to play back the captured clips (right now there's no sound). All of the data is stored like so:
I'm having to write a reporting application that gets information from some Interbase servers and it also has to work on Vista as well as XP, I'm using to connect Borlands Data Provider.[code]My Issue is that debugging on my xp Machine the dataset gets filled, debugging on my vista box it fails ("Interbase provider initialization failed"), my initial thought was that this could be UAC related but I've compiled the application and 'ran as admin' and still same issue. (by the way it failes on the line Dim da as BdpDataAdapter...)
In VB 2005, I am calling a C++ DLL function that returns the address in memory and size in bytes of a jpeg image. How can I load that jpeg image directly from memory into a picture box in my VB form? I cannot afford to save it to disk first.
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?
Attempted to read or write protected memory. This is often an indication that other memory is corrupt. Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

Im designing a web browser and i continue to receive this error after going to about 3 websites it crashes with that error.
I have a BackgroundWorker object that I instantiated to perform a DB process on a background thread ansynchronously. I have event handlers for DoWork and RunWorkerCompleted. I can tell that the BackgroundWorker is disposing of itself because I added a message box into the Disposed event handler.Is it necessary to detach the event handlers to ensure that the memory is cleaned up and that there are not memory leaks?
I've noticed that every time I start a new thread in my program, the memory usage jumps about 1000k and it never goes back down. I have ensured that the thread is no longer running, and only one instance of my worker thread is ever running at a time. I am using ThreadPool.QueueUserWorkItem and ASyncOperation to get stuff done. The program starts using a Sub Main in a module that uses STAThread; I read that using STAThread instead of MTAThread makes it impossible for the Garbage Collector to get in and consider objects for garbage collection. However, when I change the STAThread to an MTAThread, the WebBrowser control in my frmMain cannot be instantiated.
I get this exception:
Code: An unhandled exception of type 'System.Threading.ThreadStateException' occurred in System.Windows.Forms.dll
Additional information: ActiveX control '8856f961-340a-11d0-a96b-00c04fd705a2' cannot be instantiated because the current thread is not in a single-threaded apartment. I do threading with the WebBrowser control, so will using MTAThread fix my problem? If so, how should I partition my code so that the WebBrowser control won't be affected by the above exception? I call the thread repeatedly with a timer (although only one instance ever runs at a time), and my program's memory usage starts at about 5000k and can jump to 300,000k+ depending on many times the thread needs to be called.
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) Microsoft .Net Framework 2.0 Service Pack 2

All the security updates and hotfixes for Widows XP.
The follow code can be called about 6K times on the server it is run on then gets a out of memory error in the last catch statement. I don't see what is wrong with the code, it works well up until the out of memory..

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 have a new problem with this same Form Printing project and I get exactly the same exception but from the different point of code:
line 538: d.PrintFunction(c, typePrint, mp, x, y, extendedHeight, ScanForChildControls)
The exception type is System.AccessViolationException and it says (after I translate it from my own language in which the message is given in my pc, into English):"Protected memory was tried to be read or written. This often indicates that the other memory is damaged"
I am getting the following error: "Attempted to read or write protected memory. This is often an indication that other memory is corrupt". i am using interop service.
This code was put together for a one time run. It's purpose is to count all the pages in a group of images. After about 6000 of 1,250,000 images in ##X it throws an "out of memory" error. Besides it being thrown together for a one time run does anybody see anything obvious that could be causing the error?
I am using the following function to return the primay ip address with out problem until I ran it on a virtual server. It returned the ip of the physical server not the virtual server.
Public Function fnGetIPAddress() As String Dim IPAddress As String = My.Computer.Name Try
I need to define Virtual IP programmatically (Perl or VB or CMD or java).I need it for temporary use, I can't use any actual IP address and I don't care if it will be accessible only from local machine.
I want to create virtual directory using vb.net. But while creating permission denied error occurs.If im manually creating virtual directory no error..
I'm trying to create a custom keyboard for my accounting firm. I have all the buttons and button events sorted out.How can I make it so that when buttons a pressed, the text is input into where the cursor is? Currently i put the cursor for instance in an excel cell, then click the key on the virtual keyboard and nothing is inputted into the cell, i assume because it selects the keyboard window when i click the button. For some keys I'm also simply using:SendKeys.Send("q") for example.
i am trying to make a virtual piano.in that i am also playing music files which is recorded through the above said piano.but how can i understand when this music playback ends.i need to invoke another function when the plyback ends.so how can i understand when the playback end.
I am trying to use fluent nhibernate in a MVC project. It seems the entities should have properties that are virtual and the set should be private for IDs. I use vb language. So tried using overrideable. It gives an error...
Public Overridable Property DesignId() As Integer Get End Get Private Set(ByVal value As Integer) End Set End Property
It says property cannot be overrideable because it has a private accessor.
