• SQL Server dtexec

  I understand to schedule an SSIS package to run, I need to use the dtexec utility. I want to schedule the job right within SQL. I walked through how to set up the job, but I really could not decipher the proper syntax to use as a Step. I have the following: dtexec /File "C:\...file.dtsx" Is the the proper way to schedule and execute an SSIS package or is there some other way I should be doing this. The pacakge will run unattended nightly. I am using SQL Server 2005. Thanks for the information Hi, yes the command line syntax can be a bit daunting.

• Visual C++ First painful steps with VC++ Express 2005 Beta 2 and DirectX9

  Hi! I am currently making my first experiences with .NET programming and the Beta 2. My first questsion is simple: Is there any way to rename the default "Form1" class/files (which are created when generating a new Forms project) in an easy way I solved the problem by searching for all occurences of "Form1" through the whole solution and replacing them by e.g. "MainWindow". This seems very complicated. My second question is more complex. I tried to use DirectX in an .NET Forms applivation. I use a form with a single button an want to play a sound when clicking that button (this is only for testing). When calling the following line:   ...Show All

• SQL Server DB Mirroring VS. Clustered Failover Questions

  We are planning to update our two node, active/passive clustered system to SQL 2005 from SQL2K. Would we be better off to use database mirroring rather than clustering with failover I believe mirroring takes 3 systems rather than two (one for each mirror and one for monitoring), but can the monitor be a rather low powered PC Our current cluster uses two 4-processor Dells and an external PowerVault RAID array with fiber channel connections. Each server has two NICs, one for general network and one for heartbeat and a fiber channel card to connect to the external PowerVault. Here are my questions: 1 - If I understand it correctly, mi ...Show All

• Windows Forms CheckBox does not update bound DataSource on click

  It appears that clicking on a CheckBox does not update corresponding DataSource immediately, but rather waits for the CheckBox to lose keyboard focus before doing so. Is there any way to trigger that update immediately, as soon as the CheckBox is clicked Are you using VS 2005   If so, you need to set the DataSourceUpdateMode to OnPropertyChanged.  To do this, click on the CheckBox and in the designer, select (DataBindings) -> (Advanced).  In the dialog that pops up, select the CheckState property (or Checked property) and set the Data Source Update Mode to "OnPropertyChanged".

• .NET Development Can I Limit rows returned in native data grid in VS05 and SQL Server?

  I don't know if this is the right place to post this, since it is a tooling question, but I am pulling back rows in a native data grid from SQL Server - I don't see an option where I can define how many rows to return (or limit rather). It looks like it is fetching it in blocks, which is good - -but I just want to return the first 100 rows let's say -- can I do this One way would be to add "TOP N" to your SQL: SELECT TOP 100 * FROM ...   ...Show All

• SQL Server Reading Excel Sheets - Column DataTypes - Change default

  Hi, I am reading Excel sheets using the Excel Source in a Data Flow. The driver decides the data type of the column based on the first 8 ( ) values which it reads. How can this default be changed to, say, 1000, please This is because I am reading columns in which the first, say, 20 cells have no values and this is causing the driver to make ALL the values in the column to be null. Thanks. That's correct, this is not a connection string option for the Jet provider. Once upon a time, it was theoretically a connection string option named MaxScanRows for the Excel ODBC driver, but oops! someone forgot to actually i ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Vertex Tangent in left handed

  I'm working in left handed corrdinates and calculating the tangent to do normal mapping transforming lights to tangent space The result is working wrong as it seems that one axis is flipped (the left side of a mesh is being iluminated as should be the right side). So I am guessing that I have a mix with the coordinate system in calculating the tangent for the vertex or in the tangent trasnformation matrix. 1) Calculate tangent in left handed coordinates VECTOR3 GetTangentSpaceVector( const VECTOR3& position1, const VECTOR3& position2, const VECTOR3& position3, const VECTOR2& uv1, const VECTOR2& uv2, const VECTO ...Show All

I've tried every login name, default, user I can think of but it rejects all of them.
