I can't find the vb.net code to make PHP connection while read the script before it would redirect to mysql database. As I have store the local host in the php script with the username and password, so I would not need the code for mysql at this present moment.
View 5 RepliesI am connecting to a data stream that pushes data continuously and when I tried to set up a network stream I just could not connect and kept getting the 'not found' error. I used the httpwebrequest with webrequest.keepalive = true and started to consume the data by reading into a buffer and then appending to a stringbuilder. Once the stringbuilder reaches max size I flush it to a text file. The problem is that I get disconnected from the data stream because I am not reading the data fast enough. I need to keep the connection open and read the data while ensuring data gets stored in text files. If I use method "CONNECT" it does not connect to the stream.
While (True)
webrequest = DirectCast(Net.WebRequest.Create(url), HttpWebRequest)
webrequest.Credentials = New System.Net.NetworkCredential(username, password)
webrequest.Method = "GET"
[code]....
should I increase the buffer size and if so what is the max? that would mean I can read more data at a time and keep up with incoming push. Disparate here.
ACtually also I noticed that it gets stuck on this line
numbytesread = responseStream.Read(bufferread, 0, BUFFER_SIZE)
and then eventually I get disconnected.

View 6 RepliesI want to read a tab delimited file so i set up a data reader with the following connection string: [Code] However when I do this it doesn't seem to delimiter at the tab characters (I cannot work out why it is breaking up the data where it is). the first few lines of the csv are in the attached "dbamstr.txt" - the select statement I am running is: "SELECT * FROM dbamstr.txt".
View 3 RepliesWe're converting a Classic ASP site to an ASP.NET site. One function was to upload a 'template' of data in CSV format for importing into the database. There were several different record types in there (the first field always indentifies the type of data).The task was to get the CSV into a DataTable so it could be validated (new project is to have MUCH better validation rules)
The code seemed pretty straightforward - watered down (taking out comments, Try/Catch, etc) it is as follows:
Dim da As New System.Data.OleDb.OleDbDataAdapter
Dim cn As New System.Data.OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & strDirectory & ";" & "Extended Properties=""Text;HDR=No;FMT=Delimited;""")
[code]....
The DataTable (dtData) is populated, but only starting with the second line of the CSV file DESPITE the fact that "HDR=No" is in the connection string.
I'm using vs2010 and can't get this to work. The same code has worked in earlier versions. What has changed?
config file:
<appSettings>
<add key="ConnectionString" value="Data Source=MikeLaptop;Initial Catalog=AdventureWorksDW2008R2;Integrated Security=True"/>
</appSettings>
Code:
Dim strProvider As String = ConfigurationManager.AppSettings("ConnectionString")
strProvider is always = nothing
How to do this now?
