• .NET Development Interop, pinning and delegates

  A hopefully simple question. Win32 functions like ReadFileEx take a function pointer for later callback. Interop-wise I've defined this as a delegate [DllImport("kernel32.dll", SetLastError=true)] public static extern bool ReadFileEx ( IntPtr hFile, byte[] lpBuffer, uint nNumberOfBytesToRead, Overlapped lpOverlapped, CompletionDelegate lpCompletionRoutine ); Where the completion delegate is defined as: public delegate void CompletionDelegate ( uint dwErrorCode, uint dwNumberOfBytesTransfered, Overlapped lpOverlapped ); This all works fine, but I've a question. Some time can elapse between the ReadFileEx call and completion of the I/O (when the delegate is cal ...Show All

• Windows Forms Alter the Close_button event on form

  Hi, I want when the user clicks on the Closing button(red cross) of my form, that my Form isn't closed but made unvisible(frm.visible=false). Is this possible and how would this be done Grtz Annihil8 Hi, A not very logical solution is to have a bool variable to check if the user press your real exit button (if you have one) instead of the "x" button of the form. // Place this code in your form's constructor, don't forget to declare the flag variable outside the constructor to give it a public access in your class flag = false; // Place this on your exit button or where you plan to really close your form flag = true; this.close(); // Place this in your form's Form_Closing event if (!f ...Show All

• .NET Development About the finalizer thread and thread-safety

  I'm using C++/CLI. I have some classes that control some native resources (objects from an unmanaged 3rd library). In the finalizer, before deleting the native objects, I need to call a native method of the library to "de-attach" them (remove them from a list, etc.). The problem is that this library is not thread-safe and, since finalization happens on a separate thread, it's my understanding that random crashes may happen during the lifetime of the application. Is this correct Is there a way to have the finalization thread blocked/not executed when execution is inside unmanaged context (or have finalization at the same thread as the application's ) Is requiring from the user to call Dispose the only solution for cleaning up resources, in ...Show All

• .NET Development One Standard: JavaScript Both Client and Server. Is it Possible today?

  I am enamored by the idea that I could actually program the client and the server using the same language. I want to use Standard ECMA script on both the client and the server. Is this possible today in a safe way without going back to classic ASP Here are my requirements: 1) Be able to create objects exactly the same way both (cut and paste) on both client and server. 2) Be able to use Lambda functions the same way both client and server. 3) Be able to use "eval" both client and server. 4) Retain dynamic typing in all of it's glory both client and server. 5) The ability to use the .NET framework (CLI) standard server-side. What I don't require: 1) Uber-high performance (unless I have too, heck I'm alread ...Show All

• Visual Studio Team System Replacing Labels using MSBUILD and TFS RC

  Hi, I have successfully upgraded my B3R server to RC, but I have a problem now. I'm using TF Build and it has started failing when it tried to label a workspace when the label already exists.

• Visual Basic Setup Produced By "Build, Publish" Gives Error After I Uninstalled VB With CD And 'Removed' All Installation CD Programs

  Hello, I created a setup file from my application. I did this because I want to put my application on other PCs without installing Visual Basic. I basically want to just run the applicatoin on other PCs. What I did to create the setup file was within VB I clicked "Build" then "Publish." I then wanted to test the setup file on my PC, so I removed everything given to me by the VB installation CD! So, I uninstalled VB using the installation CD. But, I also had to go to the control panel to remove some of the programs that the installation CD gave me. I did this because the uninstall via the CD left things on my system that the installation CD gave me. When I was done, the control panel, remove programs listing ...Show All

• Microsoft ISV Community Center Forums How do I create and use 3D ranges in Excel-VBA

  It is easy to create and use 2D range in excel. The following code will do Option Explicit Sub Demo3DRange() Dim sh As Worksheet, r As Range, vData Dim Row As Integer, COl As Integer Set sh = ThisWorkbook.Sheets("Sheet1") Set r = sh.Range(sh.Cells(1, 1), sh.Cells(100, 2)) vData = r.Cells.Value For Row = 1 To 100 For COl = 1 To 2 Debug.Print vData(Row, COl) Next COl Next Row End Sub When we execute the above code, the variant vData will become a 2D array of 100*2. Now my question is following: A)How do I create a 3D range in VBA code B)Can I assign that 3D range to a variant, and get a 3D array, just as I get 2D array in case of 2D range Thanks -Rahul ...Show All

• SQL Server SR 2005 - Code works in preview, but not when deployed.

  SSRS Version: 2005 I've created a report that has a simple function that cycles through a multi-value parameter list array and returns a string value of each list item that was selected seperated by a comma. I use this so I can display in a textbox which items were selected. The code works when you preview the report in the designer; however, once it's deployed onto the server, the textbox that calls the code displays: #Error. I've been researching this problem in other forums, but the only thing I've come across talks about security permission when running a custom assembly. I'm not using any custom assemblies. Can anyone help me out with this problem and let me know how to resolve this issue Below is a copy of the code I'm using. ...Show All
