  Using the property grid and custom PropertyDescriptors to gather user settings. All works fine - except where is the "Reset" context menu when right clicking a property - as when using the property grid in a designer. Why missing when used in application code I'm pretty sure I'm providing the correct attributes etc. Update: I forgot to look at the PG methods. Use this: private void resetToolStripMenuItem_Click(object sender, EventArgs e) { GridItem item = propertyGrid1.SelectedGridItem; if (item.PropertyDescriptor.CanResetValue(propertyGrid1.SelectedObject)) propertyGrid1.ResetSelectedProperty(); } ...Show All

  I am building a simple utitility to be hosted as a database assembly in SASS 2005. This is a .Net Assembly] My method is date dependent and I want to pass in a DateTime rather than a string (globalisation issues.. you know the story).  Can I do this and how would I pass this parameter in an MDX query I also want to pass in such thigs as the StorageMode enum etc. Presumably I can pass in the integer value... (kinda defeats the reason for using enums though) Well, it seems that after due consideration I have to answer my own post! I think the problem is that we can only really pass in basic value types via text in queries, essentially strings and numbers. If I really want to pas ...Show All

• Windows Live Developer Forums Very Beginner Question

  I know that I can use Microsoft maps in my website, or my desktop application . my Question is Is it a must to be connected to the internet to use Microsoft Maps, or it can be cached, downloaded..etc I appreciate your instance reply. Thanks in advance. The 3D control maintains its own data cache, and it's possible for it to operate in a disconnected state. This would only be available if hosting in a managed application as you obviously couldn't get to the web site if you were disconnected. If you are viewing the site and the network becomes disconnected, the 3D control will continue displaying data from the cache until the network becomes connected again. ...Show All

• Visual C# Passing a method to a method?

  I'm trying to abstract my code and I noticed a pattern. I'm sure that this can be done, but have no idea where to start looking for an answer: Say I have the following method: private static void ArrayLengthTest() { if (al.Count > 0) ReserveMedia(); else { NoRecordsMessage(); Console.ReadKey(); Console.Clear(); CreateMainMenu(); } } How would I cleanly pass ReserveMedia() or any other method name I know I could create some switch logic and pass an option, but that would be really klugy. Any ideas/hints would be appreciated. TIA - AbeR You can pass methods as delegates. You'll have to define a delegate type that defines the method's signature. Then, define a method that takes of ...Show All
