• Visual C++ Use of HTREEITEM in /Clr

  HI, When compiling an app that uses HTREEITEM i get an error complaining about _TREEITEM - _TREEITEM does not seem to be defined. I am currently trying to see if this will work: typedef struct TVITEM *HTREEITEM; Any hints on how to get around this I can confirm that the use of typedef _TREEITEM {}; solved that problem. I have not tried fiddling with the Lean and Mean def's as it seems inconsistent to do so. If afxcmn.h is included then the typedef above should occur regardless. The code uses #define VC_EXTRALEAN - it is quite diverse, but is mainly client side DBMS using ODBC with common controls. Thanks... - Tim ...Show All

• Visual C++ How to compile C++ function to be used by C# ?

  I want to write a native C++ function that I can later access from C#. Please keep in mind I do not have much experience developing on windows, (mostly unix) and that my only windows compiler is VS2005. I tried creating a MFC DLL. I am able to access this from a C++ .net program, but not from a C# program using P/Invoke. It seems that a plain MFC DLL is not "good enough" for use with DllImport. Is this correct It seems that I have two options: 1) compile the C++ function as a COM DLL (not sure how to do this from VS2005 - I don't see an option for that). I see an option for an ActiveX DLL...I hope I don't need to do th ...Show All

• Visual Studio Express Editions Random Letters

  How do I get a Random Letter I think I need to first get a Random number, then have the number = a Letter i.e A=1, B=2 etc but how do I do this This might help: Dim str As String = "" Dim i, n As Integer Dim c As Char Dim rand As New Random For i = 0 To 9 ' Length of string required n = rand.Next(65, 65 + 26) ' A thru Z c = System.Convert.ToChar(n) str = str + c Next MessageBox.Show(str) It's perhaps not the best way of achieving this, but it works...

• Visual Studio Capturing Text Output from Exec Task

  Is there any way I can capture the text that is output to the console while executing the <Exec> task to a property I'm porting my NAnt Scripts to MSBuild and we Create SCM ChangeLists from the exec task. I'd just like to extract the ChangeList ID. Chike I checked the msdn2 page for the Exec task ( http://msdn2.microsoft.com/en-us/x8zx72cd.aspx ) and it says: One disadvantage of using the Exec task rather than a more specific task is that it cannot gather output from the tool or command that it runs. At the risk of sounding silly, maybe you could pipe the output of the command to a fi ...Show All

• Visual Studio 2008 (Pre-release) Intermediary router and interoperability

  Greetings, I am currently designing a solution which requires to have a high level of interoperability. The services will be used by external clients but also by internal applications. For me it would make sense to have 2 different bindings for both audiences. One would be wsHttpBinding for external clients and the other would be netTcpBinding so i can get the best performance for my internal applications. One thing though, is that i don't want to expose these services directly to the outside world. (They are deployed in a secured zode). Therefore i want to use a router similar to the one in the SDK (Intermediary router) that i will ...Show All

• .NET Development Implementing ISynchronizeInvoke when using System.Timers.Timer

  MyObject is running on the main thread.  MyObject.Start is called which calls an unmanaged API to begin a process. It then starts a System.Timers.Timer for 5 seconds in the future The Timer elapses and called MyObject.Stop which calls into the unmanaged API to end the process. Of course this is called on a secondary thread. I suspected that this wouldn't work becuase the unmanaged API doesn't like being called from 2 threads and it turns out I am correct. I have come to the conclusion that if I make MyObject implement ISynchronizeInvoke then I can pass in 'this' as the . SynchronizingObject property on the timer and I ...Show All
