• SQL Server "login failed for user" message when executing a copy of a working package

  I notice when I copy an SSIS package 'A' to a new package 'B', the new package 'B' will generate a "login failed for user" message in the data flow components. To copy I "save copy of Package 'A' as." Some config info: Package ProtectionLevel = EncryptSensitiveWithPassword Connections are Data Sources Connection strings with password are stored using PackageConfigurations to an SQLServer table. I've verified Package 'A' is in fact using the config table (e.g. it is not using a password or user stored in the package) Data connectios are all SQLServer Native OLE DB Client The account is an SQLServer account (not integrated security) The original Package 'A' works flawlessly and I get success when I ...Show All

• .NET Development problem in running 2 threads

  I have a function which connects to the server (it is a synchronous connection) and returns bool value based on whether the connection got successful or not. While connecting to the server I would like to show progress bar on the UI. I have used separate thread for connecting to the sserver and I showed the progress bar in the main thread. I am starting the progressbar once “connect button clicked” and I will stop the progressbar run after “connect to the server function” returns. Once the “Connect” button clicked I started the “ProgressBar” running and also I started the Thread for connection to the server. Since the connection to the server is synchronous the whole application got hanged while connecting. Even the progress bar running ...Show All

• .NET Development XML, Excel, VB.NET and some guidance ...

  Hello, Is the a way i can acomplish these tasks : a. Within a windows form, open an xml document ( i use spreadsheet 10.0 com object ) from a specified location , b. Save it, also as xml, but somehow index it, so when i open it ( just like point {a} ) not to use the absolut path of the file ( C:\ Documents \ ... ) but rather this index. I chose this approach because the environment i work in is not organised, files are often moved, and so on. Also, for this i was thinking to create a service based on the fileSystemWatcher events ( changed, moved, etc ). I observed that class is able to determine, in case of a moved file, the new location. Please, if someone could help me, i would really appreciate it ! P.S. I promise to r ...Show All

• Visual Studio Documenting overloaded methods and Sandcastle

  I'm a bit of a newbie using Sandcastle, so please bear with me. I'm at a lost. I cannot find out how to document the collection of overloaded methods. For instance. Say I have four overloaded Add() methods: public void Add( string name) public void Add(string name, Socket socket) public void Add( Socket socket, RobotPart robotpart) public void Add(string name, Socket socket, RobotPart robotpart) It looks to me as though Sandcastle, by default creates a folder for all of these Add() methods, and randomly chooses one of the headers as the folder name (again please bear with me about the names I am using) Now, within a summary tag for another method, say GetSomething(), I want to place a tag which wil ...Show All

• Windows Forms Iterating an enumeration with a timer control

  Experts, I'm attempting to create a windows form with a picturebox (circlebox) that is redrawn every 5 seconds with the next value from the Graphics.SmoothingMode enumeration (example: First it is drawn with SmoothingMode.HighQuality, then SmoothingMode.HighSpeed, then SmoothingMode.None, etc.).

• SQL Server Login failed for user 'sa'.

  Hi, I am running Ms SQL Server Standard Ed. with IIS 6.0 on a Windows 2003 Server. Currently having some problems relating to access to database. IIS seem to work fine, as the welcome page which doesn't require access to the SQL database can be opened without a problem.
