what i would like..This code to run under a connection string called strSQLSelectQuery in form2

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.
I have an application that I'm trying to use a textbox to store a form name:
Dim strName as String = frmMain.txtFormClose
Dim frm as Form = strName
frm = strName
frm.show
or
frm.close
and I get an error stating a string can not be converted to a form or something.
I'm trying to open and close forms in my application, based on the string text in my open and close textboxes, but it's not working.
Is there a possibly way to add a string value into the Form Text Properties, so that I can have a customer name and job number display there? In other words... a variable form name. I have tried using an ampersand command and even even using quotes.

I have two forms. on the first form I have a button which calls another form that has a List Box.

list box.

I am struggling a bit with a string conversion. My platform is VB in Visual Studio 2010, windows form application. What I have is a Single float that occupies four characters of a string. Where Chr(0) is the LSB of the single and Chr(3) is the MSB of the single. This string is loaded by a built in function that communicates to an external microcontroller via tcp/ip that I do not wish to modify. I am having trouble figuring out a way to get these chars from a string to a single data type. I dont need to convert the data, just move it. But I keep getting type errors and not sure how to handle it in VB.

I am trying to convert a string to a single. Ive tried csng() directcast() and single.parse. The first two methods crash. Single.parse says input string was in incorrect format. The number is 777.7932 so should convert fine. Ive tried it this way:
'x = single.parse(pts(0), globalization.NumberStyles.AllowDecimalPoint)
how can i convert a string representation of a single data type that is read from a text file into its single data type. I checked control panel and globalization settings are set to english.

While searching on how to escape a single quote in String.Format, I found the answer at SO: Escaping single quote in String.Format(). It seems to be different for VB though. I tested it, and indeed C# needs
string s = DateTime.Now.ToString("MMM d \'yy 'at' H:mmm");
while VB needs
Dim s As String = Now.ToString("MMM d 'yy 'at' H:mmm")
Why does C# need a double backslash, and VB a single backslash? This might be a bit of a silly question to C# users, but while I can read C#, I'm not used to writing it.

I would like a count of every time it makes a change. Possible?
If not, is there a clean way to do a multiple incident replace within a single string and have it record counts?I know I can create loop throughs but they are slower and messy.

vb.net Dim xfont As New Font(font_cbo.Text, font_cbo_size.Text, FontStyle.Regular, GraphicsUnit.Point)

I am trying to do a SQL query that checks for the presence or absence of a character's occurance in a field / column as a condition to retrieve the row. In this case I only need to test for existance of the specified character and in a similar query to test for the non existence. Not where it is or how many, just is it there or is it notI am using VB express.net 2008 and it uses, I think, MS SQL Server 2008.Using VB's instr() I can tell straight away if a string does or doesn't contain a character, but I would like to know this before I retrieve the row.
using the
WHERE .... and [mytable.myfield] LIKE 'Q'
or
WHERE .... and [mytable.myfield] NOT LIKE 'Q'
produces a result, but not a correct result. It does something but I can not say that it is working even part way.CHARINDEX gets an undefined function error MATCHES also gets an undefined function error?CONTAINS looks like it should work but I am still getting sytax errors with it, so I don't know how to use that predicate yet.
I got a string array & I need to show the contents of it to a single label. It acts like a clock. The thing is I tried with everything I could but I failed. This is the code I've been trying. Its in vb.net. And theres a thread running to slow down the loop so I can display the contents in a label for 2 seconds.
Dim j As Integer
For j = 0 To readText.Length
label.text=readText(j)
Thread.Sleep(2000)
Next
