View 4 RepliesI'm kinda new here, and I didn't know what forum to put this in, so I just put it here. I wanted to load an assembly to an Application Domain, use it, then unload it when I'm done with it. The assembly uses too much memory. The problem is: After I unloaded the assembly, the memory used is not getting freed. I was watching the performance all the time. The available memory increases only after I close the whole application. And that assembly is the only thing that uses a lot of memory in my application. Here's the code I used to load and unload the assembly: How can I free up the memory without closing my application. The memory was suppose to get freed up by simply unloading the assembly that uses it much.
View 2 RepliesI have a system that must do massive array operations. Often I have many arrays with 1 to 2 million elements at same time.
Usually I create the arrays inside a procedure, so, I expect when the array variable goes out of scope, the array becomes available to the GC. But in the near future, I'll need to do these operations in a "looping" way, so I'll create and delete the arrays many times...
Will GC free the memory associated to the arrays "in time" for the next loop or it is best to "force" it in someway, like using the erase statement? Or maybe I'm completely wrong?
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

I have a small app, that takes items in a listbox, and loops through them..Ive noticed that the memory usage just keeps getting higher and higher and higher until it crashes, how can i track where its no relasesing the memory?I am using the web browser control, and anytime i go to a new page, the memory useage goes up, and stays up..All other loops i have wont make the memory usage go up, only when i use the web browser.
View 4 RepliesLately I have been making a program (I guess you could call it a trainer), which would read the process memory to get the character's coordinates in a game. It later makes a simple map and show it in a separate windows. I built this program in VB.net, and it works surprisingly well. The only problem is the fact that the memory address where the coordinates are stored, changes every time I restart the game. Could someone please help me find a way, for the program to find the correct address by itself? If it helps, the game I am referring to is Minecraft.
View 2 Repliesvb 2008 compared to 2003 is the ability to drag controls onto the web form and place them where I want.With 2008, the form places the control to the left and I have to tab, space, set-up tables or similar techniques to get the control exactly where i want it. Is there a way to make the web form in 2008 work like the one in 2003?Other then this one oversight, I enjoy all other aspects of vb 2008.

The problem is that it displays always zero percent why?
I've got a form - CMCConsole It pops up a dialog form for adding a new case.If the matter number in a textbox on that dialog form matches an existing cases matter number I would like to find it in the binding source of the CMCConsole form
Private Function CheckMatter(ByVal MtrNum As String) As Boolean
Dim cfIndex As Integer = CMCConsole.caseBS.Find("MatterNumber", MtrNum)
Dim cfIndex2 As Integer = CMCConsole.casefileBS.Find("MatterNumber", MtrNum)
[code]....
But it appear the filter for the CASE we were just on that is set on the binding source is keeping the FIND from seeing other cases.
caseBS.Filter = "CaseId=" & e.Node.Tag.ToString
Do I have to clear the filter in order to find a matter number in some other case??

View 10 RepliesIm 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 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?
View 1 RepliesI'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.
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!
Have you ever heard about that error ? It happened to me when I used code to Close an open form . But this very strange . Not only I have used this simple code (Me.Close) in numerous forms but it also happens in a weird way . You see , I have a form with a button on it . The code in the button's Click event sais Me.Close . Also , this button is set to be the Cancel button of the form . Now , when the user closes the form either by pressing the X button or by pressing the above button , nothing happens . However , and this is very weird , when the user presses the Esc key on the keyboard , the program crashes with this error message :
