What would you need to do this for?
I don't know about changing the name but you don't have to do a 'add web reference'. you can dynamcially choose webservices on the fly as well as point to different locations for test/qa/production/etc...

Hi,
I'm having FileStream.Write behave rather oddly.
The code below should take file a.txt and append it to file b.txt :
Dim buffer As Byte()<br />
Dim bytesRead As Integer<br />
Dim fStreamIN As New FileStream("c:\a.txt", FileMode.Open, FileAccess.Read)<br />
Dim fStreamOUT As New FileStream("c:\b.txt", FileMode.Append, FileAccess.Write)<br />
ReDim buffer(fStreamIN.Length)<br />
<br />
bytesRead = fStreamIN.Read(buffer, 0, fStreamIN.Length)<br />
MsgBox("Read bytes:" + Str(bytesRead) + " Expected:" + Str(fStreamIN.Length))<br />
MsgBox("byte 1:" + Chr(buffer(0)) + vbCrLf + _<br />
"byte 2:" + Chr(buffer(1)) + vbCrLf + _<br />
"byte 3:" + Chr(buffer(2)) + vbCrLf)<br />
fStreamOUT.Write(buffer, 0, buffer.Length)<br />
<br />
fStreamOUT.Flush()<br />
fStreamIN.Close()<br />
fStreamOUT.Close()
I test with :
a.txt "abc"
b.txt "<this is="" the="" orig="">"
Now when I run this code, the characters in a.txt are read correctly to buffer, but the file b.txt contains :
"<this is="" the="" orig="">扡c"
What on earth is going on ???
cheers guys

You need to read it as text, not bytes. The odd character is probably caused by the file containing some sort of encoding identifier at the start, which you then appended blindly on the end of the file.

I want to add a warning:
Your code is unsafe, you somehow expect a number of bytes being read that could
differ from what you ask, but you don't use it when writing the data.
bytesRead = fStreamIN.Read(buffer, 0, fStreamIN.Length)
...
fStreamOUT.Write(buffer, 0, buffer.Length)
it should have been: fStreamOUT.Write(buffer, 0, bytesRead)

I am building a 3 layer solution.
Well, I use the data application block from enterprise library 3.1 and visual studio 2005.
I have configured my app.config with the editor that enterprise library recomends. I have defined my connectionstring and my provider.
When my application run, appear a error, objeto no referenciado.
It is generated from my dataaccess layer.
Someone says to me that app.config must be in the client layer.
I have put my app.config in my dataAccess layer. It can be?
So,if my app.config is in the client layer, Do I need define something else or my application block will recognize it automatic?
Tanks in advanced

At a guess you are coming from an access environment where you can have calculated or virtual columns.
These do not exist in SQL Server. You have 2 options
1 do the calculation in the select query when you retrieve the data
2 create a view of the table with the calculation in the view.

If you are updating the record through SQL command then use format(date,"yyyy-mm-dd").
Hope this will help.

if your program is in visual basic .net then following statement may solve your problem
date.ParseExact(DateStringFromUser,"dd/mm/yy" ,new system.Globalization.DateTimeFormatInfo).ToString("mm/dd/yyyy")

Hi sheikh,
Thank you for your response.
While I debug the application, it is showing "String was not recognized as a
valid DateTime"
Please advise me

date.ParseExact(DateStringFromUser,"dd/mm/yy" ,new system.Globalization.DateTimeFormatInfo).ToString("mm/dd/yyyy")
here date from user is the string user enters and the next argument is the format of the string entered by user
i.e if user enters
"03/08/2007" then the format is "dd/MM/yyyy"
and the argument in ToString method is the format you require to use

Hello Friends,
I want to write a prg., which will have a Rich Text Box. User can enter & format text. Can be saved in a RFT file. I know all that stuff. My point is, user will open a rtf file, select customers to send the letter to. I got to merge the letter and the addressed of the customers and the user can print Page wise. Can I save it in a new rtf or doc file? I want similar output as we do in Word.
Is this kind of application possible! If I let this application make from some one, how much should it cost (Just to make my work easy, want to know)?
I want to make it, how do I make it. Any guidlines, reference, help is highly appreciative.
Thanks
Terry

save only text not the tag how can i do this.Currently i am doing as
If (xMsg.MessageParts(x).ContentType = "text/html") Then<br />
body = CType(xMsg.MessageParts.Items(x), Indy.Sockets.Text).Body.GetText()<br />
End if
if the mail contain html table and i checked with
type=xMsg.MessageParts(x).ContentType then is type variable
shows text/plain format and if i checked with
Dim s As String = xMsg.ContentType then it shows correct

Can anyone help me its urgent.
I have added a new sheet on an xlt file and add it to the code which is:
Public Sub Survey_1(ByVal report As String)
Dim stored_func() As String = { _
"[Production charts - Survey_1 - Export prices]", _
"[Production charts - Survey_1 - Export Price increase]", _
"[Production charts - Survey_1 - Export Price decrease]", _ <-- this one
"[Production charts - Survey_1 - Price increase by product]", _
"[Production charts - Survey_1 - Price increase by location]", _
"[Production charts - Survey_1 - Capacity]", _
"[Production charts - Survey_1 - Capacity expansion]"}
CreateReport(stored_func, report)
End Sub
Im getting the error on this side of the code:
Dim db1 As New DbTier
db1.DbSource = GetSetting("Server", "Data Source", "CSR", "")
db1.OpenConnection()
Dim i As Integer
Dim wb As Workbook = mvarExcel.Workbooks.Open(mvarTemplate)
Dim ws As Worksheet
Dim rg As Excel.Range
Dim drd As OleDb.OleDbDataReader
For i = LBound(stored_func) To UBound(stored_func)
ws = wb.Worksheets(i + 1)
rg = ws.Range("DATA" & i + 1) < ---- bug here
rg.ClearContents()
If i = 0 Then ws.Range("csr_title").Value = mvarCsrDetails(CsrIndex.Title)
drd = GetDataReader(db1, stored_func(i), mvarCsrDetails(CsrIndex.ID))
Dim r As Integer = 0
Dim c As Integer
While (drd.Read())
r += 1
For c = 0 To drd.FieldCount - 1

RaiseEvent OnAfterEachProcess(stored_func(i))
Next c
End While
Call AdjustRange(ws, "COL1S" & i + 1, False)
Call AdjustRange(ws, "COL2S" & i + 1, True)

That is not nice around here. It'll just piss people off.
As far as the error is concerned, Exception from HRESULT: 0x800A03EC, those are notorious for not being very descriptive. Check that you don't have old processes running from previous debug sessions, and also make sure the parameters are called correctly. MSDN can be of more help...
