• Windows Forms Window shrinking on restore.

  I'm using Visual C# 2005 Express to make a windows forms application. The application works fine but when I added some user settings to keep track of the window size and position, the window shrinks to no size when the window is restored. If I start the application, resize the window, and close it, it will remember its size and position on restart. When I minimize the window and then restore it, however, it briefly returns to it's original size (a fraction of a second) and then resizes itself to have no client area at all. I can then manually resize it to it's original size. What is going on Thanks for any help. Bob I am experiencing the same problem with bound control properties. I don’t save window position ...Show All

• Visual Studio 2008 (Pre-release) Data Binding and Exceptions

  Hi, I'm trying to use data binding with properties of a business object that will validate its data in the property setter and raise an exception if invalid. Everything works fine only if I add the fake ExceptionValidationRule to the Binding which is not very convenient if I have to do for every properties I want to bind to!!!! Is there a way to activate this behaviour by default or is there any callback triggered each time a binding is bound to a dependency property I looked at OnPropertyChanged but it doesn't tell which dependency object changed and the new value does not contain the BindingExpression object. I tried adding a handler for the Text property change of a TextBox like that: AddHandler(TextBox.TextChangedEvent, new RoutedEven ...Show All

• Visual Studio How to correctly register a custom logger in an IDE's BuildEngine?

  Hi again, In my endless search for a solution, I'm trying yet another method, but I'm still running into a wall. I am trying to register my own logger class into my solution's build engine. I get the instance of the engine like so: this.m_engine = Microsoft.Build.BuildEngine.Engine.GlobalEngine; and then on the OnBuildBegin event, I try to register my custom logger as follows: if (this.m_engine != null) { this.m_engine.RegisterLogger(this.m_logger); } This calls my logger's Initialize() function correctly, and just before the OnBuildDone event fires, my logger is Shutdown(). However, my logger's hooks into the IEventSource (to capture the errorraised and warningrased events) don't seem to be firing in betw ...Show All

• Visual C++ C++/CLI destructors and finalizers chaining

  According to the topic "Destructors and Finalizers in Visual C++" in the "C++ Language Reference" implementing a ~ destructor or a ! finalizer automatically chains to base classes which have these semantics after the derived class destructor or finalizer code is run. However it is suggested in that topic that the C++/CLI programmer call the finalizer at the end of the destructor processing. Would not this then mean, in that idiom of calling the finalizer of a class from the destructor of that class, that the order of destructor calling whenever a destructor is run would be: 1) destructor of derived class -> finalizer of derived class ( through suggested call ) -> finalizer of base class ( through chaining ) -> ...Show All

• Visual Studio Team System get latest on checkout macro

  We just started using team system, and were switching over from vss. We're used to the vss get latest on check out way of working. I know there's a million reasons given as to why this is taken out in team system...but our team wants it to work the regular way (it's to the point where superiors will can the product if a workaround isn't found). It's currently our only draw back to fully using team systems for all internal projects. I posted the macro mentioned on other posts to accomplish this functionality below. My question is how do you set this up to work Does it work automatically when you check a file out Do you have to bind it to a button that you hit when you check it out Any help or solutions will be greatly appreciated. ...Show All

• Windows Live Developer Forums Auto select all

  Is it possible to have, when signed in, all contacts selected Jeroen Hauser wrote: Is it possible to have, when signed in, all contacts selected Hi Jeroen, "Possible" of course, but "likely", no. The only scenarios that would benefit from selecting all contacts are to export the entire address book to another contacts manager, or to send spam to everyone in the address book. That's not what the contacts control is intended for. Our goal is to make it easy for end users to use of their contacts with third party web sites in everyday scenarios, such as shopping, sharing, and socializing. None of those scenarios require *all* the contacts in the user's address book. ...Show All

• Visual Studio 2008 (Pre-release) Storyboard pause behavior

  I have a storyboard animation running forever and want to pause it when the element is not visible - the animation continues to run as evidenced by cpu usage. When the animation is running, cpu usage is about 22%. With storyboard sb, sb.stop stops the animation (cpu approx 0%) and returns the visual appearance of the element to the initial appearance. sb.begin(me,true) starts the animation again. When sb.pause is used, the visual appearance freezes and the cpu usage drops to 8-10%. When sb.resume is called, the visual appearance jumps ahead to some appearance proportional to the amount of time since sb.pause was issued. So, it looks like sb.pause freezes the visaul changes but does not pause the animation clock. Is this corre ...Show All
