• SQL Server Cursor with parameters?

  Hi, I'm kinda stuck with my function I'm creating. I want to iterate over a cursor in a cursor. I've found an example in the documentation of SQL server. The iteration is no problem for the first cursor, because that cursor is built up with a plain sql-statement with no parameters...however the second cursor should be executed with parameters which were fetched from the first cursor. I'm coming from Oracle and there it's very straightfo ...Show All

  Before installing the finished version of MS C# Express 2005 I reformated my HD and reinstalled a fresh version of Window XP-Home.  After first installing VB Express 2005 which works fine, I installed C# Express 2005.  Projects which were created before the final version of C# Express work fine.  But when I try to open a new project I get the following dialog box: "The filename, directory name, or volume label syntax is incorrect ...Show All

• Software Development for Windows Vista FileWatchService and State Machine Workflows

  I have a question in regard to the FileWatcherService activity available for download and how to incorporate it with a statemachine workflow. I am developing a state machine that will react to files being dropped into a FTP store.

The FileWatchService will need ...Show All

• Windows Forms Beyond MDI

  Hi- I'm looking to build a Windows Forms application that builds on the idea of MDI but goes a bit further. The functionality I want is the following: 1. Dockable child windows. I know there are controls out there that give you docking capability, but I need them to be child windows because of #2.... 2. Dynamically loaded child windows depending on the existence of a DLL in the application root. This is for add-on modules (dll's) that I'd like t ...Show All

• SQL Server How to close all open "handles" to a SQL Server 2005 express DB?

  Hello all! I'm trying to create an application which makes a copy of the database file it is using on application start and can restore it at any time, if needed (little project about SQL injection, so I need the copy ;-) ). This works fine, but as soon as I make my first connection to the db (connection_object.open()) and close it again I can not access the file anymore, because it is "in use by another process". How can I release all ...Show All

• SQL Server Am I missing something???

  So I'm using the new Microsoft SQL Server Management Studio (aka Enterprise Manager)... 1. So I load it up, add a few sql servers to it. Mess around, close it, open it again and lo and behold it didn't bother to keep any of my settings or any of the SQL Servers that I had added and anoyingly asks me for login information to add another one.  Unless I'm missing something, you just threw out one of the best parts of Enterprise Manager. Please ...Show All

• .NET Development Can WMI be connected over HTTP?

However, the next version of Windows Server, R2, will support it via WSMAN (WS-Management tool). There is a new WS-management standard for carrying managementcommands as SOAP messages over HTTP. You can find some mo ...Show All

• Smart Device Development Redistributing static libraries?

  I have a static library which is currently available on Win32, Win64, Mac OSX and Linux. However I'm interested in a qualified opinion if it's realistic to create static libraries on Windows CE My library is written in C++ but exports a C frontend. However I'm in doubt. There exist atleast 4 different processor types (x86, mips, sh and arm) and on top of that lots of different SDKs. I mostly only use CRT functions, STL and a few Windows specif ...Show All
