• Visual Studio How does assembly ref debugging work?

  I copied a dll I had created to another folder and then attached a reference to it (from a WinApp). If the dll build is Debug I am able to step into it and it even finds the original path of the source code. A Release config, obviously, cannot be stepped into. I opened up the dll in ildasm and I didn't see anything that helps VS2005 track this. How exactly does this happen seems the path is there after all, I checked some dlls, they all contain something like this: RSDS D:\\path\\to\\dllname.pdb I also found the reason for problem I mentioned previsouly: seems I forgot the entire directory tree was moved to another disc, the dll still contained the path to the previous location... Interesting. edit: checked the dlls with a hex edit ...Show All

• Visual Studio 2008 (Pre-release) Reading and Writing image "Rating" metadata

  I'm looking for a way to read and modify "Rating" metadata that Vista uses to rate image files. I'm able to read the rating although I noticed that the rating is written in several places in metadata... and I'm not sure which Vista is using... it looks like all of them are changed at the same time and are kept in sync... so do I have to modify all of them to keep them in sync /xmp/Rating / xmp/xap:Rating /app1/{uint=0}/{uint=18246} When I'm trying to modify the rating... nothing happens...

• Visual C# Go to class member quickly using keyboard only

  I'm migrating to VS 2005 (C#). Up to now I've been using VS 2003 with Resharper. I see VS 2005 now implements many of ReSharper "goodies" (refactor, rename, add 'using' etc). However I still can't go to a class member quickly using keyboard only. E.g. in ReSharper (VS 2003) I'd press a shortcut which would display "file structure", then a member would get selected as I type letters it starts with, hit enter and I'm in the member. Long time ago (VS 97/VC++ 5.5 I think), "Class Members" combo box (VC++ editor) were "trackable" (i.e. selection would position on the member starting with the letters type) and one could assign shortcut to expand/focus on members combo box. It's long not the case a ...Show All

• Visual Studio 2008 (Pre-release) What facilities does WPF have for restricting input to a text box?

  I'd like to prevent my users from entering negative numerical values. You could add a custom ValidationRule which tries to parse the input value into a number. If the number is negative, return a ValidationResult which indicates failure. Or you might want to throw an exception in the setter of the property which is bound to the TextBox if the value is negative. The WPF binding/validation system will catch the exception and register it as an error associated with that binding. Or handle the TextChanged or KeyDown event of the TextBox and validate the input value as the user types it in, and disallow negative values that way. ...Show All

• Visual Studio 2008 (Pre-release) Duplex works from Server to client (callback) but not client to server

  I have specific problem: When I send strings from my client app to my server, the server responds as if it has received something but that something is always null. The response (callback) to the client works perfectly (eg. an echo). This sounds like im always sending the server null but i've confirmed the following: the parameter is not null on the following method public void Msg(string _msg) { base.Channel.Msg(_msg); } Any insight would be awesome. Thanks Thanks for the response! First off, im using the NetTcpBinding, tried with both no security and message security.
