[mapguide-users] How to prepare unmanaged DWF Drawingsource?

[Brad L]

I use the file system to get the name of the folder in the unzipped dwf.  The
folder name is the same as the sheet attribute you need.

here is a function in VB to get the Name of the folder.  It should be easy
to convert to C# or just drop it in your appcode folder as VB code.

Public Function get_sheet(ByVal resourceName As String) As String
        Dim folderlocation As String =
ConfigurationManager.AppSettings("dwfpath") & resourceName & "\"
        Dim dirinfo As DirectoryInfo
        Dim myName As String = ""
        For Each dir As String In Directory.GetDirectories(folderlocation)
            dirinfo = New DirectoryInfo(dir)
            myName = dirinfo.Name
        Next
        Return myName
    End Function

After you have the sheet name you use DOM to replace it in the drawingsource
and layersource template files or just build the XML document in memory. 
Then you can add these to your repository.

There are 1000 ways to skin this cat.  You could find a second party .Net
class that works with zip files or use the windows API to work with them or
take the easy way out as I did and unzip them all to a second directory and
work with it that way.  Whatever route you choose the information you need
is contained inside the dwf and the dwf is just a zip file (replace .dwf
with .zip and have a look).
