Reading A Result From A Database To A String?
Feb 22, 2010
I have a database (SQLExpress) to populate my web page with some products.
Some times, I want to perform an if else function to the result (which seems to be very difficult in asp.net for some reason - compared to asp.classic).
The code works fine
string PN = (Convert.ToString(ds.Tables["B2B"].Rows[0]["PartNumber"]));
Is there a better way to do this? Or is this the correct way?
Second question is:
ds.Tables["B2B"].Rows.Count;
also works. correct my terminology but the ds parameters(?) Tables, Rows and Count all belong to ds. How does any one know this? How would I know what else I can use with ds? I have viewed the microsoft website to try to work out what I can and can't apply and have gotten no where! Is there a site which says if you use XX, then you can use the following parameters.

Is there a reason why i get different result when reading collections using WebConfigurationManager.GetSection method.
It sometimes returns values correctly in the Hashtable and at other times returns nothing for the same data. Its inconsistent.
client:-
Hashtable hsh = (Hashtable)WebConfigurationManager.GetSection("test1");
Config:-
<section
name="test1"
type="System.Configuration.DictionarySectionHandler"
/>
<section
name="test2"
type="System.Configuration.DictionarySectionHandler"
/>.......

I m reading different names. My problem is
1) Name shouldnot begin with hyphen or Apostrophe.ex: 'john or -john , both are errors
2) Name should not contain hyphen+Apostrophe or Apostrophe+hyphenEx: O'Brain is correct and O'-Brain is wrong.
3) Name should not contain space+Apostrophe or Apostrophe+Space Ex: O 'Brain and O' Brain , both are wrong. but Billy-Bob is correct
4) Name should not contains Hyphone+space or space+Hyphen. Ex: O- Brain and O -Brains, both are wrong

I am trying to read data from excel file in asp.net. I have added the connection string to webConfig file:
<add name="xls" connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=HPM_DB.xls;Extended Properties=Excel 8.0"/>
But it shows me an errormessage when I run this query:
string query = "Select * from [IO_Definition$]";
IO_Definition is the name of the spreadsheet in my excel file. I also added the excel file to the App_Data folder of the website.
The error is:
The Microsoft Jet database engine could not find the object 'IO_Definition$'. Make sure the object exists and that you spell its name and the path name correctly.
The thing is, when I write the absolute path of the excel file in the connectionString it does work. Is there anyway I can make it work without writing the absolute path?

I have an ASP.net/VB.net website, and want to make an inquiry of another website to obtain particular information for use on my site in string format. For example, I have used the code:
Result01 = "http://api.hostip.info/get_html.php?ip=" + Variable01
which only produces the other website address as a string. However, I want to get the actual result of the inquiry as a string. I have experimented with System.Xml.XmlDocument coding, without any luck. the proper coding to get the results of such an inquiry as a string?

We'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;""")
Dim cd As New System.Data.OleDb.OleDbCommand("SELECT * FROM " & strCSVFilename, cn)
cn.Open()
da.SelectCommand = cd
da.Fill(dtData)
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. What am I missing here?

I have an c# Class Library where I need some dynamic template based text. Instead of inventing my own template parser I thought I could create an aspx file in my project that is executed at runtime and, instead of viewing the output in a browser, I want a StreamReader or string object that holds the result.

my ASP.NET application reads an xml file to determine which environment it's currently in (e.g. local, development, production).
It checks this file every single time it opens a connection to the database, in order to know which connection string to grab from the Application Settings.
I'm entering a phase of development where efficiency is becoming a concern. I don't think it's a good idea to have to read a file on a physical disk ever single time I wish to access the database (very often).
I was considering storing the connection string in Application["ConnectionString"].
[code].....
I didn't design the application so I figure there must have been a reason for reading the xml file every time (to change settings while the application runs?) I have very little concept of the inner workings here. What are the pros and cons?

I am trying to return single string result through a stored procedure and Linq. This works fine when I test the stored procedure but it is not returning the value to the page. The value returned is always 0 which is the return value. This is the stored procedure:
ALTER PROCEDURE Login
@CustomerName nvarchar(50),
@Password nvarchar(50) output
As
Select @Password=Password
From Customers
Where Customers.CustomerName=@CustomerName
This is the vb
ALTER PROCEDURE Login
@CustomerName nvarchar(50),
@Password nvarchar(50) output
As
Select @Password=Password
From Customers
Where Customers.CustomerName=@CustomerName is the code created by the designer
This is the designer function
<FunctionAttribute(Name:="dbo.Login")> _
Public Function Login(<Parameter(Name:="CustomerName", DbType:="NVarChar(50)")> ByVal customerName
As String, <Parameter(Name:="Password", DbType:="NVarChar(50)")> ByRef password As String) As IntegerDim result
As IExecuteResult = Me.ExecuteMethodCall(Me, CType(MethodInfo.GetCurrentMethod,MethodInfo), customerName, password)
password = CType(result.GetParameterValue(1),String)
End Function

I have the following data that basically I only need a few bits of information from: The only things I need from this are:
Patients Name
Drs Name
Patients Phone Number
Appt Time
Appt Date
and the rest of the information I can discard. A customer uploads this as a .csv file (even though it really isn't as you can see) and I'd like to parse the needed information and post that to my SQL database and discard the rest. I think I can do this with a dataset but I've never built that before. The fields from the customer will always be the same and the fields I will need will always be the same. Also, the date time has to be in the format of yyyy/mm/dd:hhmm and the phone number always has to have 512 as a prefix. Here is the code I currently have for my site:
