I've been using some memory profilers to try and track down a memory leak - but am swamped with posibilities.
Am wondering if anyone has a function to dump all memory allocations that are present as a form closes/disposes.
I'm very interested in languages and their underpinnings, and I'd like to pose this question to the community. Are the following analagous to eachother in these languages?

I am trying to view all the properties of this:
Dim IISOBJ = GetObject("IIS://LocalHost/W3SVC/1")
For the life of me I can't figure out how to display all the property names of this object.
This current project involves dumping parts of WinAD objects into a db to search from.I am trying to make this go a bit faster. there could be 10s of thousands of records to create.So i figured threads would do the job.I have tried straight of creating new threads for each db insert. that does not work for long, after 1700 threads it crashes.
t = New Thread(DirectCast(Sub() MySQLLib.group(dmn1, grpn1, grpd1), ThreadStart))
t.Start()

Is there a way in .NET (VB.NET or C#), when an exception happens, to dump the stacktrace of each thread? Basically I would like to reproduce what happens in Visual Studio's Debug->Threads window to see what each thread was doing when the exception happened
View 2 RepliesI use this code to create dump files of my database.Now what I want, if possible, is to encrypt it so that when it is viewed in notepad or anything similar, average users cannot read it.

I know it sounds an odd request, but in order for others to gain access to an executable's VB.Net source code long after I have left the project I wanted to add something that could output the source code to notepad. This would be triggered by calling the exe with a numbner of parameters passed, like a pass phrase.I know how to pass the parameters and can call a proc based on what is passed, but I don't know if it's possible within that proc to dump the entire program's source code to notepad.

View 2 RepliesI have a third party GIS tool that I'm using to view maps with. Occasionally we have to take a snapshot of a portion of the map and dump it to a bitmap. The third party tool has a function that will give me the upper left and lower right coordinates of the area selected on the map. These coordinates come out as system.drawing.point objects.
The two point objects are then used to generate a new system.drawing.size object that will give the height and width of the area selected. The height and width values are passed to the constructor for the system.drawing.bitmap.All this works fine most of the time. Sometimes, however, when the user selects a particularly large area, the bitmap constructor bombs with a 'parameter is not valid' error. There isn't any documentation on this error, but I'm assuming it means the height and width are too big.
So what I'm wondering is... is there some way to check my height and width values prior to creating the bitmap and make sure they are in acceptable bounds?

I have this code which saves the dump file in a static path or destination Process.Start("C:xamppmysql inmysqldump.exe", "-u root ipoint -r C:Backupipoint.sql") MsgBox("Backup Database Created")
I want to choose the path by using the folder browser dialog which will put the path on a textbox but this code below doesn't work Dim path2 As String = tb_path.Text Process.Start("C:xamppmysqlinmysqldump.exe", "-u root ipoint -r '" & path2 & "'ipoint.sql") MsgBox("Backup Database Created")
In Windows 7 if I launch Task Manager and select a process (eg:Notepad.exe) I can right click on this and select "Create Dump File".
This creates a dump of the file to my hard drive.I would like to do this programmatically.

Of course, if it encrypted, it has to be decrypted before querying the dump file. I have no idea what encryption I can do in vb.net and mysql
I modified my first code
Process.Start("C:/MySQL/bin/mysqldump.exe", " --host=localhost --user='" & strUser & "' --password=1234 """ & strDbName & """ -r """ & strPath & newDBName & """, --cipher /e /a '" & newDBName & "' ")
But the output file contains nothing whatsoever.

I have a VB.NET 2008 program that crashes about once a month at a customer location. My log file does not include any clues of the crash, the program just dies with the infamous SEND / DONT SEND window.So I need to setup my customers so that in the event of a program crash, a DUMP file is created automatically, without any user intervention. Everything I read on internet indicates that the drwtsn32.exe program does that.

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 :
Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

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.
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.
