• Visual C# COM Interop and Finalize

  Our company does quite a bit of development in .NET for COM which involves the CCW. Unfortunately, some questions have arisen regarding the CCW and the C# destructor execution. Specifically, does setting the .NET object in an unmanaged environment result in a call to the destructor I would imagine that it does not because .NET is non-deterministic, meaning that the garbage collector takes care of destroying the object - which invokes the destructor. This leads me to believe that the destructor will eventually be called by the GC. In order to test this theory, I wrote a simple object that has a destructor. The destructor simply creates a text file and writes the date and time of execution to the file. When I create the object in the m ...Show All

• Software Development for Windows Vista FreeformActivityDesigner and Connectors question...

  Hi! I am hosting a FreeformActivityDesigner in my app which works really great. I can drag my custom shapes onto the design surface and drag Connectors between them. But i'm unable to find out how I can delete a Connector on a key press (I know how to actually delete it but I can't figure out how to listen for a key press when the Connector is selected)... I tried to override FreeformActivityDesigner.CreateConnector to supply my own connector class derived from Connector but the Connector class doesn't have any events to listen for key presses... If I override FreeformActivityDesigner.OnKeyDown, my override method is only called if the design surface itself is selected and it's not called if a Connector is selected. How can ...Show All

• Smart Device Development Debug multithreaded application on WinCE 5.0 with VS 2005

  Hi, I have a multithreaded C++ application. When I break into one of the threads, I want to see the call stack of that thread and all the other threads. This works fine, except when the thread is blocked in the WinCE kernel. For these threads, I don't get a call stack, just a single address within the kernel. At the MEDC I got the suggestion to try to load the symbols for coredll.dll, but that didn't help. How should I go about getting the results I need Antonie Bosch Security Systems. Has there been any progress in resolving this problem since the original post It remains an extremely serious problem that makes it incredibly difficult to debug multi threaded applications. ...Show All

• Visual Studio Team System Ability to incorporate relational data within TFS fields?

  I would like to add role information to a customised work item. When a user is chosen from a dropdown, I would like the role dropdown to default to the chosen user's role. Currently both users and roles are defined in Global Lists, but I wondered if there was anyway that I could move to a relational model. Can this be done Yes, moving the data to a database and doing databinding is what I'd like to do. You say that SP1 will allow the creation of custom controls - is there a URL that I can follow to get some more information on this Installing a custom control on all the relevant users' machines would would be a viable option for my work situation. ...Show All

• Visual Studio Express Editions Linking Two Forms and linking an About Box

  Hi, Question 1: I have created a form that is a main window, right. I also added another form using the "Add New Item" method. I want to be able to display the second form, Form 2, when I click on an item under a toolbar menu. How would I be able to do this without writing a lot of code. (Writing code for every setting I want to change) Question 2: I also had an "About Box" that I created the same way that I did with the first question. I want to do the same thing as the first question. Show that box without typing a lot of code, when I click on an item under a toolbar menu. I know these are nooby questions probally, but give me a break...I'm only 15 years old. If you need more info, please let me know.  &nbs ...Show All

• Windows Forms WebBrowser Control and Printing

  Hi all, I use a System.Windows.Forms. WebBrowser to display the content of a generated document. The logic requires to get notified of successfully having printed this document from the webbrowser form. How can one intercept the print button / context menu call to plug in a printed_event. Thanks This an environment with a lot of network printers, which cannot all be monitored. The first step would be to know, which printer was used. So again the question is how to intercept the print button and see which printer was used and then monitor this printer. ...Show All

• Visual C++ C++ code formating in VS2005

  Is there any way to get source code formatting working for C++ as the VS2005 already does for C# Would it be any easy (and free) way to enable or mimic the ^E + ^D, perhaps Since Microsoft is so bent on telling everyone else how to be consistent, I believe they should set the example and use one consistent editor. Why on earth would you have multiple editors for different languages One editor, multiple parsers. Fact is, Microsoft wants everyone to use C# and leave C++ - Borland C++ Builder seems to have no problems formatting C++ code. And if C# is THE language, why didn't Microsoft write Vista with it I'll give credit where credit is due - Intellisense and many of the tools in Visual Studio are awsome ...Show All

• Visual Studio Team System Files automatically get included in change sets

  I am getting reports from developers that some files, such as those with extension .pdb and some .dlls are automatically included into change sets for developers whenever checkins are attempted. I am not all too sure what the exact nature of these files are but they may be files that are related to Microsoft libraries. Developers can easily prevent these changes to be checked in by making sure that they are no checked. But is there a better way to handle this Thanks, Maggie http://support.microsoft.com/Default.aspx kbid=915110 Easiest way to get the fix is to install the Web Application Project add-in from ScottGu's website. ...Show All

• Visual Studio 2008 (Pre-release) possible 3D rendering problem

  got a 3D scene with multiple objects in it. some of those objects are 2 blocks. another object is a window with a transparent texture. but the problem is the window will see-through some of those blocks. e.g. if i look through the window to look at a block, then i can't see the block. if i don't look through the window, then i see the block. even stranger, is that the order in which the objects are added to the scene matters. if i add block A, then the window, and then block B ... then looking through the window, i can see block A, but not block B. if i add both blocks before the window, then i see both blocks. if i add both blocks after the window, then i can see neither through the window. any ideas what is happening here NOTE i ...Show All

• Visual Studio Tools for Office Cached data is destroyed upon compilation

  Hi there, This may not be a normal scenario and so I expect this functionality isn't available. I create a new Word project in Visual Studio. I have an application that adds cached data to Word documents. I add some data to the document cache. I open the document and write on it, and I add custom properties. I compile in Visual Studio, the resulting Word document in Release directory contains the text I typed, contains the custom properties, but the cache has been corrupted. The main cache title is there but the entries are not which means the document crashes when it opens complaining about the following ------------ Value cannot be null.
