Is it possible to define my list of strings like in 'good old' VB60, to use only on ebyte of memory for each character? .NET always seems to store any string as unicode, which doubles the required memory. The case is that I have a huge list of strings, all of the same size. It is about 50.000.000 items, 12 characters each. You can imagine I am running out of memory in no time. I tried converting them to arrays-of-bytes but in that case I loose the possibility to perform a "LIKE" statement in a FOR-EACH loop to check for a specific item.

I have a datalist that returns multiple entries and I need to insert values via an OnClick command for a button I have with each entry. Problem is it's saying that a label I have in the datalist is not declared, in particular the MyLabel.Text from my Insert statement below.Can someone show me with code how I can declare this label or is it even possible? When I put the label outside of the datalist, everything works fine but when it's inside it says it's not declared. [code]...

the below statment is right 100% but what i need is to change the word mobinil when the user choose another item from the combobox
cmd.CommandText = "select * from warehouse where mobinil ='" + ComboBox2.Text + "'".I thought that i can do the follwoing dim x as string x= here will be the item selected by user- and ofcourse i need it to be put instead of the word Mobinil
cmd.CommandText =
"select * from warehouse where x value ='" + ComboBox2.Text + "'" is that possible ?

I'm trying to declare an enumeration and one of the names I'd like to use for an item is not usable apparently. Where I am declaring 'STEP = 3', I get this error message in visual studio: "Statement cannot appear within an Enum body. End of statement expected." Is it possible to use STEP as an item name somehow? [Code]

I have a datagridview which is populated with information from a database. I would like it so that when I click on one of the items in the table, the information appears in the text box, or other suitable tool.
The VB output is an EPG (electronic program guide), that has a list of programs and the channels/time etc. So when you click on the program such as 'The News,' the data from the database such as 'Description' will appear in the textbox.

I have one text file with few thousand lines of information. Out of few thousand lines, few hundred lines are something like:
Copy "\server1C$abc.msi" C:windowsinstaller1abc.msi
Copy "D: empxyz.msi" c:windowsinstallermissing.msi
Now it is really hard to find manually all those statement which starts with "copy ".I would like to create another new text file with all those statements which starts with "Copy".

I'm creating a report with crystal reports where I show some fields from 2 tables.The worst thing is that I don't know how to insert an sql statement inside of a textbox. For example, wanna insert the total quantity of items of an order, (tables: items, orders).
With an SQL query is very easy to take the quantity of items, but don't know how to put the quantity in a text field inside the report designer, and there are no sql queries options in the reporter to do.

I have a list box on the form which functions as a copy/paste. When you copy something, it is automatically added to the list box as a "clipboard helper". Here is the problem,however: if the text is more than 1 line, the list box does not show all the text.It ends up looking messy.So getting back to my question, is it possible to make the list box item height for an item depending on the amount of lines that item contains?This is a one line sentence in the list box and should take up one line.This is a multi line sentence in the list box and should take up two lines for item height.

I had a small query relating to using an If statement.
Is there a short / easy way to populate 2 or more text boxes with different text if an if statement is true.
So.
If A = 1 then TextBox1 = "AA" and TextBox2 = "BB" etc
I've tried doing it with 'And' '&' but just keep getting a 'False' appear in my Textbox1 and nothing in the 2nd or 3rd.

I'm running some if statement but I have hit a brick wall with what I'm doing and trying to do. If textbox1 has a value then I run different coding to if textbox1 and textbox2 have a value - Textbox1 will always have a value. [Code] What I'm trying to do is add an additional statement if both Textbox1 and Textbox2 have text, then to run code 1 if the last four characters in textbox2 ends in .jpg else to run code 2. [Code]

I am building a small utility to transfer files. I have a list box that I am adding the file names to be moved. The question is how to I add a text and a value field to a list box item. This will not be databound it is an unbound list box. I am using this to add the filename but I want the value to have the full path for later file moving. So how do I add a value and a text to an item?
Me.lstFilesToMove.Items.Add(System.IO.Path.GetFileName(openFileDialog1.FileName))

Im trying to come up with a do while statement that reads through a text file till the end while pulling out 3 different matched items, then writing those matched items to ascending spots in an excel file, and then creating a bar graph according to the saved data. Sounds complicated but...I have the program reading the text file, pulling out the first iteration of all three, writing them to an excel file, and I have it even graphing them the way I want it to. The only thing I havent done before (and which is probably the easiest), is creating the do while statement so it keeps searching line to line for the three interactions of what im looking for and writing them to ascending spots in the excel file.
Right now my code works like this, which is perfect for pulling out the first 3 and creating a graph, I just inserting a do while and a rowindex + 1 variable.
vb Dim alines() = System.IO.File.ReadAllLines("C:deviceinfo.txt")
Dim amatch As String
Dim muvalue As String
[CODE]................
I have a feeling in order to pull this off, I do not want to use the, "ReadAllLines" option and possibly want to put the text into an array.
And do something like: if lines.count > 0
But im not familiar with how arrays work in VB, and more specifically what the syntax is. The other tricky thing I am trying to add is an if statement that adds to a variable (such as i) everytime a line is added to excel so the program will write to ascending lines. I was trying to have the it work with the do while statement but pretty soon realized that if I did: i = i +1. Everytime it went through the loop then the data was going to be on random lines corresponding to their place in the text.

I have a listview setup to act as my main GUI. Kind of like a copy of windows explorer. I'm trying to get it to open individual forms on the double click of each individual icon.
Here is what I have so far to display the text of each item in the listview. I'm not sure how to get it to do what I need though.
