Am using lots of .Net and Indesign Objects in my StandAlone APplicataion.My Application is crashing because of memory usage [Memory allocation and deallocation].Will it deallocate if i use the following for the object: Object=nothing how to free memory of .net and Indesign objects and for which i will have to free memory.
[code]When I run Module1, it creates the packet, fills in the fields, sends the bytes, and then crashes in P.Dispose when it reaches the FreeHGlobal statement.The error message is:The handle is invalid. (Exception from HRESULT: 0x80070006 (E_HANDLE))What do I have to do to free the pinned memory?
I'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.
I 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 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.
Lately 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.
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?

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..
Public Function AddUserToGroup(ByVal sSamAccountName As String, ByVal sGroupName As String) As Boolean Try Dim returnStatus As Boolean = True[code]......
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"
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 have a loop that uses threading to manage an untrappable error in a function that runs from Excel. If the function processes with out issues, Excel closes. However, if a time out occurs Excel cannot close and the following error occurs: "An attempt has been made to free an RCW that is in use. The RCW is in use on the active thread or another thread. Attempting to free an in-use RCW can cause corruption or data loss."
The error occurs at FinalReleaseComObject(Me.xla) xla.Type is Excel.Application and Excel will not close unless it is released.
How can the thread be completely closed when a time out occurs?
How can the Runtime Callable Wrapper, RCW, be freed from use?[code]...
I am writing an add-on for my intranet to allow my users to just email "itsupport" and parse the from as the user who logged the job and the body as the issue. Does anyone know if their is a free parser available so I don't have to look at writing something myself?
I need something like ObjectListView and LGPL, BSD or some license that allow its uses in commercial applicatioTo use ObjectListView commercially, companies normally buy a license. A license to use ObjectListView commercially is 100 euros for small companies or 500 euros for medium sized companies. This license gives the company permission to use ObjectListView in any and all of its closed source applications. The license fee covers the current and all future versions -- there are no upgrade fees
I can't use string.Format, I have C style format strings;I can't call the native printf (no P/Invoke);I can't use http://www.codeproject.com/KB/printing/PrintfImplementationinCS.aspx because of the license, I need something GPL-compatible.Is there a free implementation of printf/sprintf for the .net framework? Other than the above link, I couldn't find anything.
I cooked up a sprintf function that supports basic format strings, you can find it here: [URL].. I'll try to make it a complete implementation if I can.
I was wondering if you could tell me of any free libraries for the .NET framework (2.0) that you know of that can convert a PDF file to HTML or XML. I've seen several components that do the opposite, meaning HMTL to PDF, but not what I need. Essentially, I need the html version of my PDFs because I need to search through the text. Also, the Adobe Acrobat SDK is not an option for me, even though I know it has the exact functionality I need.
