One of the patches on June 13, 2006 is causing problems on some pages. A few pages to review to get up to speed and the work-around:

Do you have an ASP.Net application that will run in an Application Pool with a specific identity? Before you enter the user account in the Identity tab of the Application Pool properties dialog, you should add the account to the local group IIS_WPG. If you forget, you get permission issues. And permission issues are the hardest to fix, imho.

(I am sure you can guess why I am blogging this...)

In response to a post in the ASP.Net forums, here is a routine to upload a file to a document library.

Sub ProcessPostedFile(ByVal fileUpload As HtmlControls.HtmlInputFile)
    Try
    ' get the filename and stream
    Dim fn As String = System.IO.Path.GetFileName(fileUpload.PostedFile.FileName)
    Dim stm As System.IO.Stream = fileUpload.PostedFile.InputStream
    Dim contents(CInt(stm.Length)) As Byte

    stm.Read(contents, 0, CInt(stm.Length))
    stm.Close()

    ' get the library path
    Dim docLibPath As String = Configuration.ConfigurationSettings.AppSettings("DocUploadPath")
    ' first, get the site containing the library
    Dim site As SPSite = New SPSite(docLibPath)
    Dim web As SPWeb = site.OpenWeb
    ' then get the folder
    Dim docFolder As SPFolder = web.GetFolder(docLibPath)

    ' delete the file if it exists
    Dim docFile As SPFile
    Try
        docFile = docFolder.Files(fn)
    Catch ex As Exception
    End Try

    If Not docFile Is Nothing Then
        docFolder.Files.Delete(fn)
    End If

    ' save the file
    docFile = docFolder.Files.Add(fn, contents)

    Catch ex As Exception
        Context.Trace.Warn(ex.ToString)
    End Try
End Sub

Brian Goldfarb is soliciting help about what type of MasterPage templates to build. (He doesn't say so, but I assume he means that these would be shipped with ASP.Net 2.0 or at least downloadable.)

My response in his comments:

I think have at least a few "ready-to-go" pages would be helpful. Like SharePoint services -- some templates are full of web parts, others are just shells.

I'm working on an ASP.Net application that requires the entry of a date and time. The user interface needs to resemble Outlook's appointment form, where the date is entered separately from the time. The date box has a button to display a pop-up calendar, and the time has a dropdown that displays the work day in half-hour increments. Both boxes can be entered manually.

Matt Hawley of Excentrics World has just what I need: a Calendar pop-up and a Time Picker. Thank you Matt!!

A word of caution, however. The time picker returns the users entry/selection as a date data type. This included both the date and time. The date part is today's date, which may not be what you want...

Kent Sharkey posted the regex code necessary for ASP.Net to recognize Firefox & Netscape 7.1.

If I understood regular expressions, I would provide the update for Safari.  But I don't, so instead I'll provide you with the User Agent strings for the various versions.

Another thing I discovered...

Defining a relation/contraint between two tables in the DataSet designer does not always create the DataRelation in the resulting DataSet object.

I use strongly-typed datasets. I like the intellisense and it IsXXXNull methods. And I bind them to data grids. Everything is good.

When acting on a datagrid in ItemCreated or ItemCommand, it is common to access the underlying data. This is acheived via e.Item.DataItem. When a grid is bound to a DataSet or DataTable, this property returns a DataRowView. My lovely, strongly-typed object is gone. :(

I needed to build a page that displayed hierarchical data. So, instead of binding my grid to a DataTable, I was binding to a GetChildRows method, which is a DataRow(). My strongly-typed DataRow is back!!!

To get the strongly-type datarow without a relation, bind to dataSet.dataTable.Rows.

The Knowledge Base is your friend

For about the umpteenth time, I've seen a newsgroup question on how to merge data from two or more DataTables responded to with a link to HOW TO: Implement a DataSet JOIN helper class in Visual C# .NET. This is just one in a series of KB articles on a DataSetHelper class that can be used to address common data merging and filtering questions. They can be handy - if you want to see what's available, just go to http://support.microsoft.com and search on "datasethelper".

Wow!  I knew that there where How To articles in the KBase, but I didn't know the depth of this subject. I wonder how much “gold” is in there...
