View 1 RepliesI am trying to wirte a function for a Phone number class called "import phone number". It should take any string with 10 digits in it somewhere (and allow for an extension), and import them into it's own properties: AreaCode, Prefix, Suffix, and Extension (aaa-ppp-ssss-xxxx...).
I check the input with a regex to make sure it's valid, now i want to tokenize those pieces into their respective properties. What I have looks like this (incomplete):
Public Sub ImportPhoneNumber(ByVal anyNumber As String)
'phone number is 10-digits long, e.g.: 012-345-6789
Dim reg_exp_10 As New Regex("^((D*)d(D*)){9}((D*)d){1}(((x|ext){1}(d)+)?|D*)$", RegexOptions.IgnoreCase)

I am making a program, where the user enters 6 numbers in 6 different text boxes, and it displays the larger of those 6 numbers. But I also want to make it where if the user enters a string value (like S for instance) in the text boxes, it gives an message and says "please enter the numbers again" and the user gets to enter the 6 numbers again. But when I do try to do that, it gives an error message saying conversion from "w/e the user entered" to Double is not valid. If the user just enters the numbers, it works fine. However, I am trying to make it if the user does enter non numeric value, it gives a message window and the user can reenter the numbers again.
Here is my code Example
CODE:
This is where I am trying to use IsNumeric to show a message if a user does not enter a string so the user can renter the numbers again, but when the user does enter a string value (say in textbox 1) it gives me an error message saying conversion from "S" to 'double' is not valid.
CODE:
Then right here this is where I have my series of ifs statements, this part works fine, it displays the largest numbers of the 6 textboxes every time. Error free.
CODE:
And do this with variable number 2, 3, 4, 5.
I know there are easier ways to do these with arrays and stuff. But I am not there yet. I am still learning about ifs and stuff.

We had a wierd problem at work.SOmeone at finance tried to import a text file into their system. It complained about the textfile was in unicode format. The file contains scandinavian . Apparently the ERP system that exported the file can only handle unicode.So one of our junior programmers wrote a batch program that line by line converted the unicode file to ascii (you can't choose encoding.ANSI because ANSI is byte array)
The files are rather big, about 3 GB in size.Apparently the system liked ASCII files, but sadly after this processing the and was gone and replaced with ?So, he wrote a new batch program, this time replacing m?nad with m�nad using String.Replace The file was opened using Encoding.Default and saved using Encoding.Ascii.Now the files HAVE AND can be imported. After he explained this to me, I just went . I wish I had some nifty "you should have done this... bla bla its much easier" but I am lost here in the jungle of code pages and encodings. Can someone that has their head screwed on straight enlight us *both* about why we had this problem and how it could be handled without writing the second batch program?
Basically unicode->non unicode (ascii) with the intact. I also noticed that if I use streamreader to read an ansi file with the internal strings will show ? instead.
I am once again working on a project and have hit an absolute wall! Here is what I'm trying to do:
1. Create a Userform that has one textbox and one button.
2. Have the user enter text in the textbox and press enter.
3. Once enter is pressed have the form take the data they typed into the textbox and search a specific .txt file (beginning the search from bottom to top to find the most recent entry) until it finds a match.
4. Take the latitude and longitude to the right of the match and convert them to proper form. Right now my SQL provides live updates to the .txt file only the lat/lon come accross as |-112053440|33427640|, so I need to insert decimals in the correct places.
5. Either way, they type "c123" it will search until it matches that then take the latitude and longitude that is to the right of the match.
6. Convert the latitude/longitude into proper format because if it pulls the data as is it will appear as[urls]...
