I got a function that reads memory of another process and then uses it in different ways. To prevent the GUI from lagging, I start a new thread and executes the code in it. It runs fine, but after a while, aprox. 20 minutes, the applications stops to work and an OutOfMemory exception pops up. The thing is that the memory use of the application isn't higher that 10mb and I can't notice any high increaments either. I have tried everything to find out what is wrong, but it seems to be impossible.
My project uses a lot of System.Drawing.Image commands and sometimes it gives me the out of memory error. I was wondering if there's a way to check remaining memory left and to halt a process if there isn't enough? Or if there is a more practical solution?
I'm running VB2008 on Windows 7; I've written out a ver simple piece of code:
Option Explicit On Module
[code]....
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.
I have a project that runs perfect under windows xp. Now I have tried to run it under Windows 7 and got there a lot of exceptions under Immediate window.
A first chance exception of type 'System.ArgumentNullException' occurred in Microsoft.VisualBasic.dll A first chance exception of type 'System.IO.FileNotFoundException' occurred in LP_Wizard.exe

What wrong with that Microsoft.VisualBasic.dll in windows 7 and how i correct that problem ?
One of my VB programs has to deal with loads of data. I keep getting OutOfMemory exception while running it.I monitored the memory usage from task manager Private=495M and CommitSize=521M.
1) What is the max memory I can have per process?
2) How do I allow more memory for my this program?
I am using Windows 2008 Standard 32 bit and .NET Framework is 3.5
I have to draw something on a Image wich is captured by the Camera. This works on many Devices, but sometimes the RAM is too small or the pictures too big and the function crashed with a OutOfMemory Exception.How am I able to:a) optimize the code to prevent this Exceptionsb) Handle this Exceptions (making pictures smaller, free Ram etc.here is the code:
Dim from_bmp As Bitmap Dim bmp As Bitmap from_bmp = New Bitmap(picname)
On the FILL command the memory in the task manager gets up to about 1.3GB and then gets an outofmemory exception. Is there a way i can specify this is read-only and read-forward since i am just reading through the XLSX and not moving backwards/forwards or doing any updates? Or, is there a better way to read the XLSX so i don't have to do a file.I do not want to use the excel add-on - i just want to read straight through the XLSX file, massage the data i read and then write it to an SQL database.
Private Sub LabelClick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label14.Click, Label15.Click, Label16.Click, Label17.Click If sender.backcolor = Color.LightGray Then
[Code].....
But there are ALOT of labels (about more than 300) and typing them out (or selecting them in the menu) consumes alot of time. Is there anyway to put the rest of them? I have about 8 groupboxes with these labels that need to be changed (there is another one that doesnt need this) so they are labels inside of groupboxes.
I have created a form and display alot of icons on the location that I want. After I displayed several icon on the form then I would like to delete a couple of them but I could not find the history of location or a link to that icon so I can not delete it.

Use code tags when posting your code. Code tags are used like so =>
I have a master page than contains my ScriptManager. On a child page i have an updated panel. Inside the update panel there is a dropdowlist. When i set the autopostback=true i get OutofMemory Exceptions. All the time. also note that I have AjaxControlToolkit set on my web.config.
(Attempting managed execution inside OS Loader lock. Do not attempt to run managed code inside a DllMain or image initialization function since doing so can cause the application to hang .) in this code. Could anybody tell me, why I have System.outofmemory exception when i release arrays? There is no exception while large arrays exist so why after their realesing??
Anyone have any examples, or source code or SDK's that are FREE?I'd like to setup a simple voip program to play with.Was curious whats the simplest way of doing it, using UDP across an IP.I planned on having a server program, as i'd want multiple clients.My question is, how can i stream voice, without using alot of bandwidth with minimal delay between talking?
I am trying to figure out how to make a .SubString get the characters from right to left not left to right.Say if a user enters 123456789 in text box 1 and I use textbox1.text.SubString(0,2) it will display 12. But, I want it to get 89.I do not want it to get 98, but 89. I tried textbox.text.substring (0, -2) but that just gives an error.So if Gold is entered it gets ld
I got a panel that i am adding labels to. I have autoscroll enabled on it so when they fill the viewable space it scrolls. but i need to put the labels to the left unviewable space(when left scroll is already at 0) The label is placed but i dont get the scroll bars and i cant force it to scroll to a - value.
Is this even possible? Same thing with UP.
Or is the Scroll only limited to Bottom and Right?
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!
Not sure exactly where to begin with this one. i have a screenshot that would make this easier to ask, but I can't figure out how to post it here.

How can I apply/combine both of these so that it will figure the datediff for each row (on a datagridview), figure the appropiate case and then update each annual leave row in the database?
I'm working on a VB.Net WinForms app. This app shows rows of production lines that the user will go down row by row and print a package of ActiveReports documents. This package can contain up to 9 reports. The package is selected and told to print, it then gets sent directly to the default printer of the machine using ActiveReports' mechanism:
rpt.Document.Print(False, False, True)
These reports also use images pulled in from the file system. When they run through the rows quickly, they sometimes encounter:
A generic error ocurred in GDI+
Then followed by:
Exception of type "System.OutOfMemoryException" was thrown.
This causes some documents to not print and they have to go back and figure out which ones didn't print. I know the machine is not out of memory, so my assumption is that the printer memory is filling up or reports are trying to use the same image when printing and causing an issue there.If it is the printer memory filling up, is there any way to slow down the adding of documents to the print queue, or at least pausing to wait for space?
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"
