• Windows Forms Why does all properties get pushed into bound controls when only one property is changed?

  Hi! I have a performance problem with Databinding. Why does all data-bound controls (TextBox'es etc) read it's bound properties when only one property is changed If I have many bound controls on a form, it flickers a lot when the DataSourceUpdateMode is set to OnPropertyChanged. I have an entity object that supports the INotifyPropertyChanged event and a collection that support IRaiseItemChangedEvents (just like the BindingList<T>). When a property has changed in the entity object, the collection raises the ListChanged event with a PropertyDescriptor argument for the changed property. Shouldn't that be enough for the databinding to just update the corresponding control It seems like the CurrencyManager is just listening on ...Show All

• .NET Development xmlbulkload and namespace problem

  I'm an xml thickie and after searching for hours I can't find the answer to a problem. I have a XML filefragment to load that (simplified) looks like :- <L:Record> <L:Field>fdgdfgfg</L:Field> </L:Record> I cannot get it to load thru xmlbulk load. If I modify it to use the default namespace <RECORD> <Field>fdgdfgfg<Field> <RECORD> then it loads with this schema <xsd:schema xmlns:xsd=" http://www.w3.org/2001/XMLSchema " xmlns:sql="urn:schemas-microsoft-com:mapping-schema"> <xsd:element name="RECORD" sql:relation="RECORD" > <xsd:complexType> <xsd:sequence> <xsd:element name="Field" ...Show All

• Smart Device Development Prevent Tab Page Change on Tab Control

  Given the absence of many events for the TabControl component (understandable given that it is part of a "Compact" framework) how does one prevent the tab page changing when the user clicks on a different tab My issue is that I have some pre-conditions to be fulfilled before the tab page display (selected tab) should be allowed to change. I can't use a "Mouse click" event to stop the page change since that event is not available. Likewise I cannot hide the other tabs since there is no such property. At present I check the preconditions on the "OnSelectedIndexChanged" event, but by that stage the tab change has already been actioned. If the conditions are not fulfilled then I have to change the tab page back t ...Show All

• Windows Forms Visual Studio 2005 SplitContainer Flicker

  I've added a splitContainer to the form and placed a treeview control in one of the panels, but resizing the form causes a nasty flicker. I've tried doublebuffering the form, but no luck. Any idea's or tips.... Thanks in advance, Ok, I ended up inheriting all the controls I used and setting the doublebuffered property to true and not use transparency on any of the controls as well. It helps but makes it harder to get the look I'm after..... ...Show All

• .NET Development Failed to create an IPC Port: Access is denied.

  I have a service that registers a remoting IPC channel on startup and quite often I will get this error when the service is stopped and then restarted. It doesn't do it all the time but enough to be an annoyance and when the service is stopped I do unregister the channel. Anyone else experience this Thanks!! Hi folks, if you're running into this problem, I recommend running Filemon to see what's causing the underlying access denied. Set up Filemon to show only named pipe activity, then filter by your channel name to see only the channel you care about. This should let you see exactly where the error's coming from. You can get Filemon from www.sysinternals.com. Cheers, JJustice [MSFT] ...Show All
