Here are some general hints: alot of the time, a control will stay in use because controls events are not properly removed (the tooltip provider caused us really large issues here) or the controls are not properly Disposed. use 'using' blocks around all modal dialogs to ensure that they are Disposed there are some control properties that will force the creation of the window handle before it is necessary (for example setting the ReadOnly property of a TextBox control will force the control to be realized) use a tool like the .Net Memory profiler to get counts of the classes that are created. Newer versions of this tool will also track GDI and USER objects. try to minimize your use of Win API calls (or other DllImport calls

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 http://weblogs.asp.net/fmarguerie/cannot-create-window-handle-desktop-heap separate issue altogether that we are already addressing, we had difficulties with determining what resources were getting exhausted as well as what the limits are for these resources.We first thought about keeping an http://www.codeproject.com/Questions/891193/Error-creating-window-handle eye on the Handles counter in the Windows Task Manager. That was because we noticed that some processes tended to consume more of these resources than they normally should. However, this counter is error creating not the good one because it keeps track of resources such as files, sockets, processes and threads. These resources are 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 error creating window 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 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
