I am trying to create a console application that does the following:
1) read a text file
2) Save the content over to a SQL Server database
3) Use command line arguments to allow user to specify any delimited file
I have an SQL database set up on my web server. Is it possible to read from a table in that database and display a value in a textbox, for example? I want to store valid values in a server database and then check the entered values in the application against the server values.
View 2 RepliesI hate to ask this question on this forum, but I'm having a lot of trouble finding it on these online tutorials. Basically, I'm learning about SQL, VB.NET, and how to glue the two together, and I've learned about using SqlCommand.executeScalar() to get the first entry in a table. But that's all it's really good for, right? Or is there something more to the story here?
Basically, I'm wanting to ask about how to pull in a FULL table from a SQL database while using VB.NET, as well as how to pry substrings and stuff from it. Again I'm having to ask this on this forum because all these online tutorials seem to ignore the subject completely.
I'm trying to create a VBasic executable to read a SQL server database and produce a mailing list.I have the SQL routine working fine and had set it up as a stored procedure, but I've just discovered the manager I've written this for is an Access-type and does not have SQL Server installed on her machine. So, I figured I'd make a front end in VBasic.
Dim con As New SqlClient.SqlConnection
con.ConnectionString = "Data Source=mySQLServer;User ID=Username;Password=myPass;"
con.Open()
I was just wondering if it's possible to create an app that interacts with a database hosted on a web server... or is it only possible using VB.NET? Also if it is possible, is there any good documentation or tutorials I could reference?
View 2 RepliesI know how to select items from an array with LINQ, but what I can't figure out how to do is access a database using an IQueryable. I connected the database to my project, added two classes from the database to the "LINQ to SQL" .dbml file and saved it. In my programming assignment, I am not supposed to create a data source (table thing) to display the data, but update my own interface manually. In order to do it, I was told to instantiate this:
Private dogs As System.Linq.IQueryable(Of Dog)
(Dog is a class that I added to my .dbml file from the database file)Also, I am told it involves using a method
.AsEnumerable.ElementAt(index As Integer)
Trying to use asp.net for the first time. I want to read a single value from a sql server database.
I have configured the SqldataSource as:
CODE:
I have the above asp:SqlDataSource code on the website page. The connection string is in the web.config file. When I run the page it is all works but the required data is not shown. Am I right to think that where I dragged the sqldatasource entity is where the data result should be shown?
I have developed a VB.NET program using a strongly typed dataset. This dataset has its connection to a SQL Server 2008 R2. The software should now be additionally used offline. The database should be exported to a *.sdf database. If no connection to the SQL server is produced, the software have to try to connect to the *.sdf database.I would like to achieve:
1. Export the data in the SQL Server 2008 R2 database to a local *.sdf file.
2. This *.sdf file has to work as an alternate connection string in the strongly typed dataset.
Iam using VB.net to read an XML file in to SQL server. I am using VBs XML parser to read nodes, elements, etc. When an element's value contains a LE symbol and I insert the string in SQL, the resultant SQL record contains an Equal sign and not an LE.
I cannot examine the string for this character before inserting into SQL because I cannot find an ANSII equivalent. Normally I could find it with iPositiion = Instr("XML String", chr(??)). That does not work because there does not seem to be a number for the ?? that represents a LE. Someone suggested using 263 but that is a small o with a accent. iPosition = Instr("XML String", chr(263)) returns a -1, i.e. chr(263) was not found.
It turns out I wasn't checking the path that it was looking up, quite silly of me. Once I tracked that problem down and corrected the offending path, the reading worked just fine. Still baffled at the MSSQL issue, since the articles average less than 10 000 bytes.
Clarification:I am unsure if some of you are under the impression that the file I am trying to read is on my local machine. It resides on the web, on the same server as the script that is accessing it. Just in a different directory.
I wrote an online help desk application that includes articles. One problem I have run into is some of the articles are too long, and get truncated when I put them into my MSSQL database. I tried using TEXT and VARCHAR(MAX) as the data type, but it would still get truncated.So I decided that I would put the articles that are too long into a text file, and have my application read the text file from there. I got this code working in my development environment, but it does not work live:

At first, I thought it was because I did not change the /dev path prefix to /hlpdsk. But even after I changed it, it bombed out. What am I doing wrong?

I recently upgraded the MS SQL Server installed on my personal computer from 2005 Express to 2008 Express. Problem is when I try to add an SQL database file to a project using VS 2005 I get an error message saying that the version of my database server is not supported, I must have SQL Server 2005 Beta 2 or later installed. I didn't do it yet but I'm pretty sure that when I open the other projects that I included a database file to it, I'm going to get the same error.
My question is it possible to have two SQL Servers installed on my machine? If so, is it a good idea to have two DB servers in the same machine?

I am using a database file Database1.mdf which have a tabel called student. This Database1.mdf is simply added by using the option Add New Item in Solution Explorer. The problem is that I am to able to update the database through form and code. The code is as:
Dim conn As SqlClient.SqlConnection
Dim ada As SqlClient.SqlDataAdapter
Dim cp As SqlClient.SqlCommandBuilder
[code]....
The ds is updated at run time, but as form is closed and run again the actual database table student is not updated.I have no idea what is going on. The same code work right with Access database and SQL database but in this case it is not working. I've tried on google but not getting satisfactory answer. I've also seen a post on this site but that is about ConnectionString, not about the database update.
