• Visual Studio 2008 (Pre-release) WPF Bug or What????

  While debugging throught WPF (NO COM) I am running into this again and again. I had posted this earlier too but nobody responded back. Just wanted to know where exactly is COM coming into play. Since we are aiming for production release of our app too, wanna make sure where exactly the things are going sour. Managed Debugging Assistant 'ContextSwitchDeadlock' has detected a problem in 'C:\XYZ..\bin\Debug\NoGen.Sandbox.WPF.vshost.exe'. Additional Information: The CLR has been unable to transition from COM context 0x1a1598 to COM context 0x1a1708 for 60 seconds.

• SQL Server Object Explorer/Server Explorer Error

  I have just installed the released VS2005 as well as the released SQL2005.  When ever I try to browse my SQL Server with either the Object Explorer in MS SQL Server Management Studio or the Server Explorer in VS2005 I get the following error: Unable to cast COM object of type 'System.__ComObject' to interface type 'Microsoft.VisualStudio.OLE.Interop.IServiceProvider'.

• Visual Studio Code generation based on checked nodes within a treeview.

  All WizardPages I have seen as examples use textboxes from which GAT extracts argument values, although I need a different approach. In a WizardPage I have a treeview with dynamic filled items. I would like to create class files for every item that has been selected. Later on I also want to create class properties for every sub-item that has been selected. Lets only tacle the class generation, and so take a list of animals as an example: -Cat -Mouse -Horse -.... In the Wizard, the user can select one or more items by using checkboxes. So if they select a Cat and Horse it would generate the classes: Class Cat { // Todo: Code to write manually } and Class Mouse { // Todo: Code to write manually } -- Is it possible to create a class file ...Show All

• Software Development for Windows Vista Disable File&Registry Virtualization - for my application

  Hello, I want to know if there is a way to disable the File&Registry Virtualization for my application. I want to get ACCESS DENIED error instead of success but written in some where else in the hard disk. Is there a way (API or something) to do that Thanks. I would advise AGAINST turning off the virtualization policy for the system in an app you're distributing to other people; if you do, you will probably impede the function of legacy apps on the machine which need things like registry and filesystem virtualization. Use a manifest. As far as turning virtualization off, it's a policy under System: 'EnableVirtualization'.  It's exposed through secpol.msc if you ...Show All

• Software Development for Windows Vista UAC Shield in menus?

  Thankfully there's an easy way to add the UAC shield to buttons by using BCM_SETSHIELD. I wonder though - is there a similar option for menus somewhere The docs say that context menus are supported via DefCM but I'm really looking to add the shield icon to a generic popup menu. Can I do this without ownerdrawing it -Marton '98 or 2000 is not really the issue here. You still need to ownerdraw your bitmaps if you want the icons to look good. Contrary to what's been suggested here, transparency does not really work. (Try saving a bitmap with alpha channel and the LoadBitmap-ing it, then setting it as the hbmpItem.) Unless I am missing something and you need to use some extra-special bitmap format here. ...Show All

• Visual Basic Odd behavior on enter key twice

  Converting a program from VS03 to VS05 professional using VB... If you put your cursor after a line of existing code, and hit enter twice, it should just add a blank line and then you paste and then you paste new code and you get a line between your pasted new code and the existing code. In VS05, however, it does that and often highlights the last word of existing code so when you paste, you have messed up your code. This is an odd behavior that did not exist in VS03 and it very annoying. The behavior does not existing in any other program (like Word), so it is a VS05 specific issue. Is it a known bug or does anyone have any ideas Thanks! Bob Hi, Bob, I just gave this a try and I'm not able to reproduce the prob ...Show All
