Win Help & Html

The WinHelp (.hlp) format has been around since the very early 1990s and has now largely been superseded by HTML Help 1.x (.chm). When it comes to choosing between the two formats, however, HTML Help's dependence on Internet Explorer may be the deciding factor. For a list of the Windows versions that come with Internet Explorer installed, see:

Export Excel with custom mode

1) We need to Instantiate a workbook object:

WorkBook wbk = new WorkBook();

2) Set the ExportMode of the Exporter to Custom:

UltraWebGridExcelExporter1.ExportMode = Infragistics.WebUI.UltraWebGrid.ExcelExport.ExportMode.Custom;

3) Add a Worksheet to the Workbook:

wbk.Worksheets.Add("Grid One");

4) Use the Export Method of the Exporter to Export the UltraGrid to the Worksheet:

this.UltraWebGridExcelExporter1.Export(this.UltraWebGrid1, wbk);

5) Populate an Excel object in memory; the Excel object is then persisted as an output stream:

MemoryStream stream = new MemoryStream();

6) Write the workbook "wbk" into our newly created stream

wbk.Save(stream);

7) Create a Byte[ to contain the stream:

Byte[ bytearray = (Byte[)Array.CreateInstance(typeof(byte),stream.Length);

8) Read the stream into the Byte[:

stream.Read (bytearray, 0, (int)stream.Length);

9) Create a new Stream
MemoryStream ms = new MemoryStream(bytearray)

The server returned content type text/html; charset=utf-8, which is not supported

The following error happened when I tried to checked out or get latest with vs2005 with team foundation server.

The server returned content type text/html; charset=utf-8, which is not supported

My Fixed solution:

Connect to Team Foundation Server with vs2008 and get specific version with force to overwrite option and then close vs2008. Open with vs2005 again, the check out and check in will work.



Some solution from MSN and Post

1. Login on the App - Tier,

2. Open the IIS management.

3. In Internet Services Manager, right-click "Team Foundation Server" and go to "Properties" => "HTTP Headers".

4. Check the 'Custom Http Headers group'.

Make sure there is only one header ---"ASP.NET".

5. Also check the Http Headers of the 'VersionControl' virtual directory under the Team Foundation Server site.
