If not, select those columns to be viewed (Task Manager choose View->Select Columns... Then run your app and take a look at those columns for that app and see if one of those is growing really large. It might be that you've got UI components that you think are cleaned up but haven't been Disposed. Here's a link about this that might be helpful. Good Luck! share|improve this answer answered Oct 21 '08 at 18:06 itsmatt 23.7k879142 I ran into this problem and found my app reported 9600+ USER Objects and 1800+ GDI Object. My problem is I'm not doing anything wrong, I'm just adding a lot of items to a FlowLayoutPanel. I guess I'm gonna have to 'page' the displayed data..

on for a client is used actively, users often get "Error creating window handle" exceptions. Aside from the fact that the application consumes too much resources, which is a separate issue altogether that we are already addressing, we had http://weblogs.asp.net/fmarguerie/cannot-create-window-handle-desktop-heap difficulties with determining what resources were getting exhausted as well as what the limits are for these resources.We first thought about keeping an eye on the Handles counter in the Windows Task Manager. That was because we noticed http://www.vbforums.com/showthread.php?760377-Error-creating-window-handle that some processes tended to consume more of these resources than they normally should. However, this counter is not the good one because it keeps track of resources such as files, sockets, processes and threads. These resources are error creating named Kernel Objects. The other kinds of resources that we should keep an eye on are the GDI Objects and the User Objects. You can get an overview of the three categories of resources on MSDN. User Objects Window creation issues are directly related to User Objects. We tried to determine what the limit is in terms of User Objects an application can use.There is a quota of 10,000 user handles per process. This value can error creating window be changed in the registry, however this limit was not the real show-stopper in our case. The other limit is 66,536 user handles per Windows session. This limit is theoretical. In practice, you'll notice that it can't be reached. In our case, we were getting the dreaded "Error creating window handle" exception before the total number of User Objects in the current session reached 11,000. Desktop Heap We then discovered which limit was the real culprit: it was the "Desktop Heap".By default, all the graphical applications of an interactive user session execute in what is named a "desktop". The resources allocated to such a desktop are limited (but configurable). Note: User Objects are what consumes most of the Desktop Heap's memory space. This includes windows. For more information about the Desktop Heap, you can refer to the very good articles published on the NTDebugging MSDN blog: Desktop Heap Overview Desktop Heap, part 2 Desktop Heap Monitor (dheapmon.exe) It's possible to monitor the Desktop Heap usage thanks to a command line tool: Desktop Heap Monitor (dheapmon.exe). It would be interesting to monitor this usage directly from within applications to prevent crashes. We could let users know that all the resources are about to be exhausted, and ask them to close windows and prevent them from opening new screens. This would help to avoid the "Error creating window h

I have a dozen forms all are children of an MDI form. One particular form always fails on the first "Show" with the error "Error creating window handle", then the second time I load it, the "Show" succeeds. I'm first attaching all the forms to the MDI form Code: frmAdmin.MdiParent = Me frmAdmin.Dock = DockStyle.Fill frmAdmin.Hide() Then when the time comes to Show the form, I call a Subroutine to do the job: Code: Public Sub LoadFormAndRefresh(ByRef vForm As Form) Const C_PROC_NAME = "LoadFormAndRefresh" Try ' hide everything For Each oForm As Form In Me.MdiChildren oForm.Hide() Next Me.Refresh() vForm.Show() <------------------- fails here Me.Refresh() Catch ex As Exception If modGlobals.gDebug Then Console.Write(CODE_MODULE, C_PROC_NAME & ": " & ex.Message) oERR.LogFileError(vModule:=CODE_MODULE, vRoutine:=C_PROC_NAME, vEX:=ex, vLogLevel:=clsLogFile.LoggingLevel.LogEverything) If modGlobals.gDebug Then Stop End Try End Sub The code steps through the frmAdmin_Load subroutine with no errors then fails when back in the MDI routine. Any ideas?

It will tell you where the actual error occurs. Almost certainly it's in an event handler that is executed due to a property that you have set in the designer. For example, if you have set the Text of a TextBox then the TextChanged event will be raised and the event handler might assume that something has happened that hasn't at that stage. 2007-2016 Why is my data not saved to my database? | MSDN Data Walkthroughs MSDN "How Do I?"
