• Windows Forms Change file ownership of an output file.

  My program generate a data file, (e.g .txt) What I want to do is RIGHT AFTER the file is generated, it will 1) change the file ownership to an admin account ( i have the admin username and password) 2) change the permission to readonly for everyone(domain user).

So I do this. fSecurity.SetOwner( new NTAccount ( "domainName\\admin" )); However, I got this error message. "The security identifier is not allowed to be the owner of this object" Thanks. ...Show All

• Visual Basic Create Web-like Forms as Windows App

  I have used VS 2005 to create a family-based web site ... about 100 pages/forms consisting of mostly text with some graphics thrown in for interest. I have no intention of putting this out on a publicly-accessible server but instead had anticipated burning everything onto CD's and then distributing that to family members so that they could view the site on their own machines (XP Pro SP2) using IE. In inquiring on this forum how to do that I am told that that is not feasible and that instead I should have created a windows app and simply deployed that app to the family (via CD). That's fine except for one thing ... I don't know how to create a web-like app as a windows app. For example, as I create the app I want to be able to easily highli ...Show All

• Smart Device Development Changing Colors of Datagrid

  I have a VB.NET application running on a HHP handheld (Windows Mobile 2003). I would like the backcolor of the rows of the grid to appear as a particular color depending on their value. For example: If Cell = 1, then Backcolor = Red. If Cell = 2, then Backcolor = Blue. From reading other posts i understand I have to inherit the dataGridColumnStyle and override the paint method. I have no idea how to do this. Could someone provide a few lines of code to demonstrate At the moment all I have is this, which only colours the selected cell.

• SQL Server "Incorrect syntax" exception when prefacing SP names with "dbo." and named parameter issues

  We're currently trying to evaluate SQLJDBC 2005 1.1 June CTP's support for database mirroring automatic failover. Unfortunately we're getting unexpected exceptions for calls that work fine w/ jtds that our blocking our ability to perform these evaluations without us making substantial changes to our codebase. The first issue is with the name used when calling a stored procedure -- SP names that start with "dbo." give us the following error: com.microsoft.sqlserver.jdbc.SQLServerException: Incorrect syntax near '.'. src:{call dbo.xyz( , , , , , , , )} The call will work if we change the SQL statement to {call xyz(...)}.

• Visual Studio 2008 (Pre-release) Updating a self-hosted service

  Context I'm designing a windows service to run a self-hosted scenario of services that are loaded from GAC. I've created a "drop" folder, in which to drop the .dll of the service I want to host. My service watches this folder and when a file has been dropped in, I install it into the GAC and load the ServiceHost. Now, my trouble is that when I'm "updating" an existing hosted service, it does not reflect the updated code that I've installed to the GAC, even though I close the ServiceHost and create a new service host from the GAC. It seems to cache to original service somewhere until I actually restart my Windows service. Question Is there a way to dynamically change the hosted service without ...Show All

• Windows Search Technologies Combined IFilter + ISearchProtocol

  http://addins.msn.com/devguide.aspx defines two technologies for integrating with WDS: IFilters and protocol handlers. One of our applications stores various data and documents internally within one file. The user creates one or more of these files on the Windows file system. We'd like to expose the data in these files to WDS. So we would implement IFilter and register it for our file extension. But these files can contain a lot of data, so it wouldn't be all that useful to return all the text as one monolithic item to WDS (all that WDS could report is that the search phrase exists somewhere in our file, right ). Now, we also intend to make the data and documents within these files accessible via URLs (using a asynchronous plugga ...Show All

• SQL Server Percentage/Proportion

  I'm new to Analysis Services 2005 and MDX. I'm trying to create a calculated member that contains the proportion of cases (using [Measures]. ) for each dimension in the cube. The following code gives me the percentage of the total number of members in each dimension. This is what I need for attribute hiearchies (single-level), but for user-defined hiearchies (multi-level) I want the percentage of the above level. For example, in a time dimension, I want the proportion of cases in each year (this works) and the proportion of cases in each quarter of a given year (this doesn't work).
