Querying A Single Column And Displaying All Results In A Single Textbox?

Sep 5, 2010

I am trying to make a list, separated by a comma, of entries from a single column in a SQL database. I have been spending the last several days searching for a way to do this, but every thing I found either didn't work, or wasn't exactly what I was looking for.

The query will pull all the email address that are not null. What I need to know is how to take the result of that query and make it look like this:

email0@address.com, email1@address.com, email2@address.com, etc, etc, ...

I feel like I should know this, but for the life of me, I can't remember nor can I find it in any of the textbooks I have.

I am using Visual Basic 2010 and SQL Server 2005. I also have access to Visual Basic 2005 if needed.

SqlCommand Parameter / Replace A Single Quote With Two Single Quotes

I use SqlParameters when executing database statements. I know that I can replace a single quote with two single quotes... but in the past SqlParameters took care of this for me. I have two projects.. in one, the SqlParameter does this and it handles single quotes fine, in another, it does not and I'm at a loss why (I even copied and pasted the code):

Add More Than A Single Photo To Database (one Cell)?

Nov 4, 2011

I'm creating a database for photos'.

The issue is that I have a need to upload a set of photos to the database instead of a single photo.

This would be all fine and dandy if I knew how many photos would be added at once but in this case it could be 1 or 100.

I have my database (setup in details) and dragged onto my form. Right now I only have a picture box for my picture to place into the database.

So what's the best way to upload numerous photos to a database without having to create 10000 cells in my database?

C# - .NET Multiple Namespaces For Single Class

Sep 27, 2010

Is it possible to have a single class reside within two name-spaces and how can I do this?

To clarify: We have a class library (let say root namespace is classLib1), which has grown over time (more classes) and I want to logically group classes into different namespaces. However some of the older classes need to be grouped into these new namespaces (e.g classLib1.section1) and doing so will break legacy code in other assemblys that use this class library. So I want to be able to refer to a class using both name-spaces until we can phase the old ones out.

I can't find any information on this, which suggests there is a reason that people would not want to do this!?!

Employee Class Single Error Identification

Feb 15, 2011

I'm currently taking a newbie VB course (online) and in this program that I am writing, I am getting one error (red) that when double clicked in the Error List, takes me to the Application.Designer window and states that "Employee is a type in 'WindowsApplication1' and cannot be used as an expression." The only solution it gives me is to generate the Employee Class (in the designer). When I select that, it gives me 3 more errors (all yellow). The Employee class has been made, so I don't really know where else to go from here.[code]...

How To Compile Single Class Into Existing Project

I have a VB.NET solution (call it S1) which produces a .vb file (say File1.vb) to be compiled and then included in another solution (S2). S2 is a console app which I want to run from a cmd prompt, not VS. My plan is to shell out from S1 to run a batch file to do the compile and then copy the .dll file, overwriting the old one in S2 (then I can run S2 in a separate operation). Here's the batch file for the compile:

VB 10 Class Project/Single Array Usage?

I've found the same project on here but I wasn't even really sure if what they had up was correct. I have a pretty solid idea of how to get through this I'm just feeling a bit overwhelmed. If you notice any other errors please point them out. I'm not looking for the answer I'm just looking for the path to get there on my own merit. Here's what I have so far:

Using A Single Picture Box To Display A Single Picture Form A Bank Of Pictures?

Mar 22, 2011

I have a few problems i need to solve. Firstly, I am looking for a piece of code i can use to display a picture from a bank of pictures. It will work on the basis of generating a random number and loading a picture that corresponds to that number.

i.e. Dim RandNumber As Integer
Dim RandClass As New Random
RandNumber = RandClass.next(1, 10)
If RandNumber = 1 Then
Picturebox1.image = picture1

[Code]...

Secondly, can I then use subsequent picture boxes to display pictures from the same bank of images, without displaying the same image? Finally, I then need to be able to click the picture or a button beneath the picture to select it as an answer to a question and then the whole process starts again.
