• Software Development for Windows Vista Code Activity context menu questions

  On the code activity context menu, two of the selections are: Promote Bindable Properties and Bind Property 'ExecuteCode' (assuming that I placed a value into the Executecode property and created a handler). I'd like to have a better understanding of what these menu selections do. For example, why would a code activity, from the toolbox, have a bindable property Wouldn't that have to be a custom activity with a dependency property I created And why would I bind my ExecuteCode method to a property Thanks. So then, in the case of the Code activity directly off of the toolbox, would there be any reason that you would want to promote the ExecuteCode property For example, if I promoted the Ex ...Show All

• Visual Studio Problem debugging multithreaded application

  I have mixed C# - C++/CLI project. In C# code there is event handler which is called from a worker thread. When I set breakpoint in event handler, debugger breaks on it. When I press F10 or Step Over, debugger hangs for 5-10 seconds, at this time I see tray tooltip "Visual Studio is busy". Then the following output appears: 'CameraTest.exe': Loaded 'C:\WINDOWS\assembly\NativeImages_v2.0.50727_32\System.Configuration\6e7f914e29c6414cba7d15ee00017064\System.Configuration.ni.dll', No symbols loaded.

• Visual Studio Express Editions Where was the ojbect created?

  Hi all, I am a new guy in MFC, There is a code like this. class CScriptDemoDlg : public CDialog { protected: CScriptObject m_ScriptObj; } CScriptDemoDlg is the Dialog class, it uses CScriptObject. But when i search the whole project , i can't find the place where m_ScriptObj was initialized. Don't we need initialize it or..... Thanks for your reply. You don't need to initialize it because it's not a pointer and it has a parameterless constructor (because otherwise the code would not compile) which is called when the CScriptDemoDlg object that contains it is created. ...Show All

• .NET Development We're not supposed to use List<T> ? ( List )

  I installed FxCop and had it analyze my application. In several spots, it says: "Do not expose List<T> in object models. Use Collection<T>, ReadOnlyCollection<T> or KeyedCollection<K,V> instead. List<T> is meant to be used from implementation, not in object model API. List<T> is optimized for performance at the cost of long term versioning. For example, if you return List<T> to the client code, you will not ever be able to receive notifications when client code modifies the collection." I'm a bit weak in my OO.. so I'm not sure what "expose" really means in this context. Is this saying to not use List<T> ...Show All

• Software Development for Windows Vista Why are so many important design time classes internal only?

  I'm attempting to create an activity in a similar style to IfElseBranchActivity. This allows you to select the type of condition, and then set the properties on it. It does this by using a custom TypeConverter and overriding GetStandardValues which creates instances of the possible derived types, and then you can bind their properties. Now the first bit I've managed to do fine, but when it comes to binding the properties of the objects created by the TypeConverter, I get the error that only dependency properties can be bound. So I look at how the ConditionTypeConverted manages to create properties so that they get bound, and there are literally thousands of lines of code in internal classes like PropertyDescriptorFilter, and internal cl ...Show All

• SQL Server How to insert multiple values to a column at a time?

  Hi all, I was looking to insert multiple values to a single column at a time in SQl. Any help pleas! Thank you Hi, In reality it is not acceptable according to data normalization rules. I.e. if you want to have such behavior you should better create an additional table and have foreign constraints mapping to it. Some example: table_x( field_1 ....., field_2 ....., field_in_which_you_want_to_have_multiple_values..... ); table_y( value_identifier ....., value nvarchar(1024) .... ); So you firstly insert several values to table 'table_y' and then just add value_identifier to a 'table_x.field_in_which_you_want_to_have_multiple_values' ...Show All

• Visual C++ How to PostMessage between 2 separate applications?

  I'm trying to implement messaging between 2 different applications using PostMessage (HWND_BROADCAST, msg, 0, 0) in one, and setting a On_Message handler in the other. The idea to test this is that when PostMessage is sent from App1, App2 will receive the message with On_Message and call the appropriate handler function. Unfortunately, its seems that this setting doesnt work. I set the message ID to the same one for both applications (something like 9990) . I did a search thru MSDN and had a clue on RegisterWindowMessage but have no idea on how to implement this, especially when the messageID must be a constant for ON_MESSAGE to work. Is there any way around this problem Please limit use of this forum to C ...Show All

• Audio and Video Development How to turn Subtitles off?

  Hi there, i tried the following to select subtitles and switch them on (or off) switch (g_sub) { case "de_sub": Player.subtitle.visible =true; Player.track.selectSubtitleTrackNumber(1); break; case "fr_sub": Player.subtitle.visible =true; Player.track.selectSubtitleTrackNumber(2); break; default: Player.subtitle.visible = false; break; } The first 2 "case" definitions works well. They turn german or french subtitles on. If "g_sub=='off'" the default definition should turn the visibility off. Right Wrong. the last selected subtitle is shown, although g_sub isn't "de_sub" or "fr_sub". How can I ...Show All

    Hello, XPSP2 VB2005Express I have a very small data entry application. The database is an access database created by ADOX.

Win32 is Windows. The 32 indicates 32-bit Windows, to differentiate from 16-bit Windows. Of course, 16-bit Windows is no longer used by most everyone. Now that there is a 64-bit Windows, Win32 is misleading, since the term is often used in contexts that would include 64-bit Windows. As for the C or C++ language creating tabs, I assume you are talking about windows and such. The C and C++ languages have no windowing capability. ...Show All
