Here is what I'm working with:
Dim connstr = "data source=mydatasource;initial catalog=gcs_dw;persist security info=True;user id=myuser;password=mypassword;Asynchronous Processing=True"
Dim sqlquery = "SELECT * FROM Customer WHERE CITY = 'Anytown'"
Dim connection As SqlConnection = New SqlConnection(connstr)
connection.Open()
[Code] .....
As you can see, I'm attempting to display the results of the query to the commandline and currently all it is displaying is "System.Data.SqlClient.SqlDataReader". Where are the results of my sql query going and why can't I retrieve them?

store and retrieve image in a SQL Server database with vb.net.:Well, the application in vb.net seems to have a database which can accessed by the LAN computers so the SQL Server 2005 database allows remote computers to share its database once the other computer application requests database from the server.So, every other computer has to store and retrieve images in SQL Server 2005. For example, comp1 has to store images taken into the server and retrieve it like tableadapter.
I am using bindings and tableadapters to store the details in database and retrieving information from db. Please if you have code or anything which is working for me, please post it here... how to store image and retrieve it SQL Server through vb.net provided there's LAN computers who are also sharing the SQL Server database.

This program is very difficult for me, but I must get threw it or I cannot finish... What I am doing is making a Database of foreign Languages with the spelling of the words and the pronounciation inside the database... The USER enters a paragraph of words into the translator textbox and pushed translate. The program has a DATABANK of words with the phonetic spellings and matches the word, then translates to phonetics. The problem is that new words keep appearing inside the language. So I incorporated a Database of 2 fields

I have created a small program that performs various calculations with data entered by the user. I need to be able to save the entered values and the results on the system running the program and be able to open it at anytime in the future and have the values and results displayed in the correct text boxes. I am currently reading up on some tutorials but I was just curious as to how I can send all my data in Visual Basic to my database in Microsoft Access?

I have a report made in Crystal Reports XI. The report is generated and exported to PDF in visual basic script using COM interface. Generally everything is running smoothly, but in one case generation breaks with error: Failed to retrieve data from the database. Details: [Database Vendor Code 9421]
Database used is MSSQL 2005 connected over ODBC to CR XI. When I am opening report with exactly the same parameters in Designer, everything works fine.It looks like it is data related, but it is hard to trace since the whole report is pretty sophisticated. Anyway I spent half a day on crawling over Dr. Google and it seems that he has no clue what might be an issue.

The application must have basic functionality as to: Insert new customers into the database A search function will be needed to find a users criteria entered The more advanced features would include matching certain criteria with another for example if the data in field 1 is the same then it should match this and return the results. so for example if a person has a hobby of 'football' it will return all the people with the same hobby

theyI had a asp.net (vb) web application to store work overtime (OT) records. In SQL server, the OT table likes this, e.g.:
[Code]...
As user will input previous date OT records, so the records in db will not be in sequence. the date of records#14 is before records#13. if user want to know which OT records cover the last 2 hours, the system should retrieve record #15 (90mins) & #13 (30mins) because they covers the final 2 hours. How to write the SQL statement to retrieve the records?

I want to write a program using vb.net tht compares the name of a document on my desktop to the name of the document on the server. If they're the same then I'd like to retrieve it and have it replace the file I already have.How can i do this? Does this mean that i have to write a web application cuz i hope not. I dont no anything about those. I am using that server for storage purposes only so i assumed that i didnt need a database for the name of the document.

Created an XSD file that represents my table structure from my database. Created a class file to hold my functions such as the one below.
Code sample:
Public Function GetUser(ByVal UserID As String) As xsdUser.UserDataTable
Dim SqlConn As New SqlConnection(ConfigurationManager.ConnectionStrings("MyDatabase").ConnectionString)
[Code]....
Now it seems odd to me to have two files doing what should be contained within just one file. I feel like I should have one class file called "User" and have member variables in there along with the class functions like the one above. But all the tutorials I see are using these data tables. On top of that I'm not sure how to handle the if statement at the end of the function. I don't think I would want to return a whole DataTable since I should only have one row, and I also don't know how I would handle an error if my function is supposed to return a data table. I suppose I could return an empty one and then if the table is empty in my code then I would handle it there, but this also seems messy.
Is this the common way of retrieving information from a stored procedure? Or is there a more up-to-date method that I'm not seeing in my search results?

I was recently working on a project that involving connection to a POP3 Server. I was using this piece of C# from CodeProject[URL] had complied it into a DLL and was using it in VB.NET.I'd connected to my Hotmail Account (not many mails) and it seems to work just fine. After that, I connected to my GMail account... I stared seeing errors!POP3 is meant to fetch emails only from the Inbox. Even when I made my own program to cross-check the problem, I saw that when I requested for the number of messages, the GMail POP3 Server returned a value which is about 5 times less than the actual inbox size.
255 Emails in my Inbox?? Online it shows me 2,414 emails in my Inbox.And secondly, my MAIN QUESTION is that how does one fetch the LATEST email from the POP3 Mailbox. What I've fetched here was an e-mail with ID 1! I want to fetch the top 20 emails (that were most recently delivered to the account)...Is there any work around for how to fetch the LATEST email from the POP3 Server rather than the oldest emails? I've also tried to connect to the Hotmail POP3 Mail Server. Again a "RETR 1" command fetches me the oldest email and not the latest one!
