I am using the following code to create an array consisting of double values specified by start stop and step. The problem with that is that for some weird reason there is a calculation error that seems to originate from the for statement causing the values to drift after the 11th to 12th digit after the comma which is quite irritating for the purpose i am using it.

As Strings.Space Method , but instead space - new lines.For example:If I want 4 spaces, I can do:
space ("4")
But if I want 4 new lines,I have to do?:
VbNewLine & vbNewLine & vbNewLine & vbNewLine
Or there is another way and more effective? (such as "Strings.Space Method"for example)

Ok I am a newbie and I need to concatenate a number and an integer. Can somebody give me a idea on how to accomplish the following/I need to take the number (which is an integer from a simple math function) and the letter A and create something like "A10" or "A45" or "A123". Can someone please give me a tip on how to accomplish this?The program creates the integer by using the value of a drop down box and a reference number of 9. The maximum value will be 109 and the minimum is 10. It needs to be combined with the letter A, which does not change.

I've been looking at this for a while and I'm stumped. I'm under the impression that if I use strOpass = strOpass.Replace(":d", "Z") that I should be seeing any numbers that a user inputs the code line there will return a Z. It's not working and I don't understandI've also tried "[0 - 9]" and :z, but the program is still returning the original input.B is not giving me a hard time over that line ( no errors or warnings. ) The other statements work just fine and return a X just like they should. Here is the entire block of code:
Private Sub btnDisplay_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnDisplay.Click
Dim strOpass As String

My aim is to have a textbox in which a page of information is already written for the user to read. This box will have a vertical scrollbar, so I can't simply superimpose a button over the textbox. What I would like is to be able to have certain words underlined and in a different text colour (similar to a hyperlink), which, when clicked, will throw up a pop-up box.The purpose is to create a glossary such that if a new word is used in the textbox, I can allow the user to click on it

In VB.NET, using Interop.Excel, I need to access a cell based on a row number and column letter. I tried my luck with...
pages.title = DirectCast(wksht.Cells(rows, "D"), Excel.Range).Value
Since the parameters took type object, I figured maybe this would work, but got no luck. I also thought of enumerating each letter to a number, but the columns in the spreadsheet aren't as normal. Meaning, they're not
A B C D E F G
They're actually...
A B C D E T AZ
I don't know if this makes a difference in the numbering of the columns. The question should be obvious, but just to reiterate, how can I get a cell based on a row number and column letter?

Is it possible to write an SQL statement for MySQL which finds all rows which match a specific arrangement of letters/numbers without using REGEXP? i.e. SELECT myCol FROM myTable WHERE myCol='{number}{number}{letter}'Should return 12X and 34Y but not 123X or 34YY..SQL match on letter and number arrangement). The difference is that I have discovered that I cannot use regular expressions with the ADO.Net driver I am using. Whatsmore, I cannot update it since I am using Visual Studio 2003 which is not compatible with later versions.]

The question: better a deep folder structure or less subfolder with thousands files?
The problem: I have a VB.NET program that generates around 2500 XML files per year (circa 100 KB per file).I have to store the files on a file server (Windows 7 or NAS).On the network there are around 30 PCs using that program.I am looking for the best way to plan the structure of the folders on the file server with the goal to have a good human-readable folders structure and at the same time a fast access to the file.In the past I made a similar program with the following structure:
fileserverPC1yearmonthsfile00001.xml
in other words a folder for each PC on the LAN
then a subfolder for the years
then a subfolder for the months[code].....
this solution would produce a clearer folder tree, but more files per folder.I do not know if this could be an issue in term of speed by file accessing with vb.net programs or other third hand application.
