• .NET Development WebClient File Download Problem

  Hi, I am trying to download files from the web using System.Net.WebClient. The program works fine and I am able to download the files for the first time. But, when I try to run again I get "An exception occurred during a WebClient request". This behavior alternates for each run. In one of the threads, I read that it was because of keepalive property being set to ON on the webserver. Is there anyway I can fix the problem by some code changes. Here is my code sample. WebClient wc = new WebClient(); wc.DownloadFile("http://someurl/file1.ext", "C:/myfile1.ext"); wc.DownloadFile("http://someurl/file2.ext", "C:/myfile2.ext"); wc.Dispose(); Any help would be appreciated.

• SQL Server SQL Express with Advanced Services - what Reporting Features does it have?

  I work for an ISV, and some of our customers use SQL Server, others use SQL Server Express. I need to develop some reports, so I was happy to read that SQL Express with Advanced Services would have some (limited ) Reporting Services available. Unfortunately, the sign-up period to beta test appears to be over, and so I am left wondering exactly what functions will be available. Is there anyone out there who has played around with the beta version reporting functions Renaming devenv.exe did not work. I did find something that worked though: I extracted (using WinZip) the files from SQLEXPR_TOOLKIT.EXE Within the extracted directory, I ran the following msi: \SQLEXPR_TOOLKIT\setup\vs_setup.msi ...Show All

• Visual Basic Modifying datagrid doesnot update the dataset

  Hi folks, I populated a Sql Server table into a datagrid using SqlDataAdaptor and dataset, which works fine. What I want to do now is to update the table when the data in the datagrid is modified. I added these 2 lines, but doesn't work, ds.AcceptChanges() da.Update(ds.Tables(0)) It seems that changes to the datagrid doesnot update the dataset. Any comments appreciated. Thanks! take out the ds.AcceptChanges()   this tells the dataAdapter or rather marks the dataset as if there are no changes, as the dataSet accepted the changes and indicates that there are no changes to be made therefore nothing will be updated to the datasource.   ...Show All

• Visual Studio 2008 (Pre-release) ListView - dragging a selection box around items

  Just getting started with WPF and I am pretty impressed. One thing that I can't replicate from WinForms yet is a particular behaviour from WinForms:ListView in WPF:ListView. In a WinForms:ListView, when MultiSelect is true, then one can click the mouse button and draw a box around items to select them (just like in explorer where you can click and drag a box around some files to select them - I don't know what the correct term is - so I am going to call it a drag box). In WPF:ListView, if I set SelectionMode to Multiple or Extended, then I can select multiple items by clicking on each one individually, but I can't drag a box around them to select them. Anyone know if it is possible to replicate the drag box behaviour (Google results for th ...Show All

• .NET Development Database

  It is necessary to use a database on a local computer that will advise, that like Microsoft Access well it depends on your specification and what your application is intending to do. you can use MS Access or SQL. MS Access is ideal for local stuff, so is SQL but MS Access would be reasonable too. SQL Server is used for remote access generally and is better managed and is industry standard. Again, really depends what your application is doing and its purpose and how many other people will be using your application. ...Show All

• Software Development for Windows Vista Adding roles to WorkflowRoleCollection

  Hello, I'm developing a workflow with ASP.NET authentication. I have assigned some event handlers in the workflow a WorkflowRoleCollection in their Roles property. When I want to fill the WorkflowRoleCollection with the roles that can raise the event, apparently I don't do it right. The problem is that when I raise that event I get an exception saying something like "authorization error in eventhandler guardaHorari1", and by checking the exception details I've thought that the problem is that when it checks the role of the user that tries to launch the event agains the workflowrolecollection, it doesn't find it there. I fill the collection this way: public WorkflowRoleCollection rolsModificadors = new WorkflowRoleCollection(); ...Show All
