While rd.Read
text = New TextBox
stForm.Controls.Add(text)
text.Visible = True
text.Name = "text" & CStr(xCnt)
text.Location = New Point(122 + (3 * xPnt), 135)
text.Size = New Size(60, 21)
text.MaxLength = rd.Item(0)
xCnt += 1
xPnt += 22
End While
after the code above it will display a number of textbox in the form, next is i will input some data in the displayed textbox....

may be you can access these textboxes like normal textboxes
the only difference between the two is that one is putted at designtime and another at runtime

In this line you're already giving textbox a name and to get a data of that text box just use that name, it's simple.
E.g.
dim txtVal as string = textxCnt.text
this should do it i guess...

Either the AVI is currupted or you don't have the appropriate video codecs to decode the video stream.

Hi,
I don't understand what your question is.
However I am gathering that you want to retrieve a record by referencing an index in SQL.
In SQL you do not access the indexes, they are set up by you to enable faster querying of data.
SQL will determine which index to use based on the query you supply, which is why creating indexes is so important - create an index incorrectly and you will slow down processing.
Having said that you can drop hints on which index to use in SQL.
So having said all of this:
1 - is this of any help to you?
2 - you refer to index 5, what is index 5?
regards
Guy
You always pass failure on the way to success.

There are no numerical indexes in an SQL database. It doesn't work like an array of values. SQL Server does not guarantee the order of the records that comes out of the table unless you tell it to using the SELECT statements ORDER BY clause. For ORDER BY to work, you have to give it a column to sort on.
Once the table is returned, you can use an index number in the resulting DataTable object to get the row, though there's no real usefulness to this. Normally you'd just retrieve the one row you wanted from the database using a SELECT statement and a WHERE clause specifying a search criteria for the row you wanted.

Hi,
I need your help!!! I want to use the function StrConv("string", vbFromUnicode) in VBScript.
I found the following code, but the result isn't the same as from VBA, I tested in Excel.
Do anyone has any suggestion?
<br />
Public Function StrConv(stringData,conversion)<br />
Dim Stream<br />
Dim tmp<br />
Set Stream = CreateObject("ADODB.Stream")<br />
' Charsets <br />
' Windows-1252<br />
' Windows-1257<br />
' UTF-8<br />
' UTF-7<br />
' ASCII<br />
' X-ANSI<br />
Const UnicodeCharaset = "Windows-1252"<br />
Const BinaryCharset = "X-ANSI"<br />
Select Case conversion<br />
Case vbFromUnicode<br />
' Converts a Unicode string to Ascii<br />
With Stream<br />
.Charset = UnicodeCharaset<br />
.Type = 2<br />
.Open<br />
.WriteText stringData<br />
.Position = 0<br />
.Charset = BinaryCharset<br />
.Type = 1<br />
StrConv = MidB(.Read, 1)<br />
End With<br />
<br />
Case vbUnicode<br />
' Converts an Ascii string to Unicode<br />
Dim Length<br />
Dim Buffer<br />
<br />
If TypeName(stringData) = "Null" Then<br />
CStrU = ""<br />
Exit Function<br />
End If<br />
<br />
stringData = MidB(stringData, 1)<br />
<br />
Length = LenB(stringData)<br />
Dim Rs<br />
Set Rs = Server.CreateObject("ADODB.Recordset")<br />
Call Rs.Fields.Append("BinaryData", adLongVarBinary, Length)<br />
Rs.Open<br />
Rs.AddNew<br />
Rs.Fields("BinaryData").AppendChunk(stringData & ChrB(0))<br />
Rs.Update<br />
Buffer = Rs.Fields("BinaryData").GetChunk(Length)<br />
Rs.Close<br />
Set Rs = Nothing<br />
With Stream<br />
.Charset = BinaryCharset<br />
.Type = adTypeBinary<br />
.Open<br />
Call .Write(Buffer)<br />
.Position = 0<br />
.Type = adTypeText<br />
.Charset = UnicodeCharaset<br />
End With<br />
<br />
StrConv = Stream.ReadText(-1)<br />
End Select<br />
Stream.Close<br />
Set Stream = Nothing<br />
End Function<br />

You haven't even asked a question so there's really nothing to tell you.

To do what??

What's the "result"?? How is it different from what you expected?? What you trying to do with this code??
|
|
|
|
|

Look at the Case statements in your code. Where are these constants defined?? vbUnicode??, vbFromUniCode??
|
|
|
|
|
Const vbFromUnicode = 128
Const vbUnicode = 64

hello to all of you out their
i m using vb.net 2005, .net framework version 2.0. and trying to uploading file to my local server with my application.
the problem comes when i try to upload a file to the server, with the code
My.Computer.Network.UploadFile("C:\Documents and Settings\Administrator\Desktop\ashish.txt", "http://192.168.0.3/isol/ashish.txt", "", "", True, 1000, FileIO.UICancelOption.ThrowException)
it throw an error 404 not found
when i place a file having same name on the server, the program cannot throw any error but the file cannot be uploaded.
if i replace the code with this one, the code works fine and it places the file on the located computer.
My.Computer.Network.UploadFile("C:\Documents and Settings\Administrator\Desktop\ashish.txt", "file://///192.168.0.3/c/ashish.txt", "", "", True, 1000, FileIO.UICancelOption.ThrowException)
but this is not something like client/server this is simple network, i need to check it with online website. the server computer contain apache 2.0.59.
i think the problem is with the configuration of apache. i m working on it.
if some has any idea about that please let me know.
any kind of help is highly appreciated.

If you want to upload a file using http, you need to post the file to a web page that can recieve the file.
If you want to uplad a file using ftp, use the ftp protocol in the url instead of the http protocol.

Yes, if you want to use the http protocol. You can't save a file using the http protocol, you can only send a request to the server that contains the file data, and the page on the server can recieve the file data and save it as a file on the server.

You can't upload files to ftp when using a proxy. Try turning off the proxy, as suggested here:
