• .NET Development Service Pack for .NET Framework 2

• Visual Basic Problem in using Try/Catch/Finally

  A textbox(T_TextBox) is bound to a float-type number in a database. The innitial value of the textbox is from that column of the database. I used these codes in my program: Dim T as Double Try T = Double.Parse(T_TextBox.text) Catch MsgBox("Please enter a number for T.") Finally End Try The problem is: every time before I run the program, a message box saying "Please enter a number of T." shows up. This problem only happens at the very beggining. When I change the text later (I select another number from the database, and this is done through a combobox), this message does NOT show up. Anyone knows how to get rid of the msgbox at the begging Thanks, Lili I like TryPar ...Show All

• Visual Studio Team System CTP5 Schema Compare Errors

  Hi I have installed CTP 5 and am having problems comparing the schema of two databases. I have tried altering the schema compare options and also tried using different databases on different platforms to no avail.

• Software Development for Windows Vista How to start process in session before user logs on?

  I have a need to start a process in a session before the user logons on. On XP I used a Windows Logon Notification Package to do this. When a new session was created, Winlogon.exe in that new session called my WLNP and it was able to start the process before the user logged on. The process is used to support smart card logons for that session. I'm trying to find out how to do something similar on Vista. I know logon notification packages are no longer supported. I know how to write a service to get session creation notification, but I don't know how to start a process in the new session before the user logs on. Is there a function I can use to start a process in another session If so, I could have my session tracking sevice start th ...Show All

• .NET Development Problem with decrypting data

  I seem to have a problem with RSACryptoServiceProvider. I use it to encrypt a password that's being stored into the database. The encryption is done in a method called EncrtyptPassword: protected override byte [] EncryptPassword( byte [] password) { byte [] theResult; RSACryptoServiceProvider theRsa = new RSACryptoServiceProvider (); theResult = theRsa.Encrypt(password, false ); theRsa = null ; return theResult; } The decryption is done in a method called DecrtyptPassword: protected override byte [] DecryptPassword( byte [] encodedPassword) { byte [] theResult; RSACryptoServiceProvider theRsa = new RSACryptoServiceProvider (); // Exception is thrown at the next line ...Show All

• SQL Server SQLCE team: Call to Get___ methods entail boxing?

  Greetings - It appears in tests that the calls to the type specific Get___ [e.g. GetInt32()]  methods of the System.Data.SqlCeClient.SqlCeResultSet type result in an internal unboxing from some internal storage of values. I've been calling these methods diligently to avoid the boxing tax... Can you confirm this behavior If this is the case, will you be improving the internals or would it be better for me to wrap the native interface myself to avoid this -rory That would be easier - but performance is important. I'm using the SqlCeResultSet object as a live cursor to the in-proc database... otherwise the DataSet/DataAdapter methods make a second copy, wasting memory and degrading performance. ...Show All

• Visual Studio Express Editions If...Then for an image

  I don't know if I'm jsut doing something stupid wrong, but for some reason, I can't get this to work.  I want something like... If PictureBox1.Image is My.Resources.picture Then    PictureBox2.Image = PictureBox1.Image End If The problem lies in the If statement.  It doesn't seem to register.  Basically, I want a way to say "If this picture box is of this image then set another picture box to have the same image."

• Visual C++ Can we please get a New Forum

  I think a lot of people have questions that involve the microsoft visual C++ .net product that you feel is off topic. We are programming in Microsoft C++ and need a central place to get help from others doing the same. C++ seems to be the red headed step child of microsoft... Hardly any documentation on how to do anything in c++ officially exists; where as tons of information exists for your other languages. We need a place we can pick the brains of others that is centrally located (and hopefully getting a bone or two from microsoft staff willing to give an answer). Telling people this is off topic 200 times a day must mean there is a place for that topic missing in your forums. Wil R. wrote: ...Show All

• Visual C# Need to make my own COM server with C#

  Hi. I've tried to search, but search results on word COM at microsoft.com are amazing. Tell me please, where can I find any tutorial or example to build COM server in C# (.NET 2.0) I've found this http://my.execpc.com/~gopalan/dotnet/classic_com/com.net_quoteserver.html but it not helps to me. A COM server is simply a COM class that provides services to another component (the COM client). You create a C# COM class by creating a normal class and attributing it with at least ComVisible . You should also use Guid to specify a unique identifier. Furthermore you should create a COM-visible interface to expose to COM. The class must implement this interface and the interface can not expose non-CO ...Show All

• Windows Forms Creating A Simple Send And Receive Serial Connection

  Hey guys, I'm using the C# language in Visual Studio 2005 and have created a send and receive windows form. I've connected an RS-232 serial cable between 2 laptops. I've completed the codes here's how it works... From laptop 1's Windows form, I will open the serial port, types a string of message in the textbox and using the "send" button I will transmit this string of message across the RS-232 cable to laptop 2's Windows Form. To view the received message, I will open the laptop 2's Windows Form's serial port and click the "receive" button. The message sent by laptop 1's Windows Form is thus displayed in the textbox of laptop 2's Windows Form. However, I would like to receive the message of ...Show All
