I have a field that I display via: String.Format({0:c},amount) This produces the string "$28.28" However, when I try to convert back to a decimal amount, I get an incorrect format exception: amount = Decimal.Parse(amount.Text, NumberStyles.Currency) I also tried it with NumberStyles.AllowCurrencySymbol with the same results. I verified that the value in amount.Text is "$28.28". Am I missing something? Shouldn't these two operations use the same currency symbol and formats?
View 2 RepliesI have written a program that uses an array of the english alphabet and Morse code. I also built a form with a input box for the alphabetic information and an output box with the Morse Code. What i am trying to do is basically type a word like "Hi" in the input box and produce the Morse Code equivalent in the Morse Code output box. [Code] This works but only one letter at a time. Do i need to Parse the string of characters one at a time, and then run it through a loop like i have created?

I understand the possibilities for encrypting a connection string in .net v4. I have a win forms application that will be used by multiple people on different machines. I understand that I need to protect the connection string at time of the app being first run on the target machine. However I am concerned that for a period of time my connection string will be unencrypted. I am looking for advice in how to deploy my app with the connection string already encrypted or encrypted during installation. encrypting the connection string in a secure way?
View 1 RepliesI'm developing an app in vb.net (visual studio 2008). I have a Teradata back-end that will be supporting multiple users in a production environment. I need to use variables in the connection string as the user/pass will be changed every 3 months.
For the gist of the application:
In it's most basic form - I have a search form which works correctly - it pulls results into a listbox and the user then double clicks the list box which will then open a form that is bound via table adapter to the back-end table (Teradata). My connection string is fine everywhere in the application. My problem is using a modified connection string for the "fill" function of the table adapter once the form is opened.
I'm using the code below for the on-load event and keep getting an "invalid connection string" - again, the connection string works fine everywhere else in the app, and the variables etc... are working correctly.
Private Sub adaptertest_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

View 1 RepliesI am making a change to an existing process. Currently the csv file (which can have embedded "," with the field in quotes), i being passed as an
IO.StreamReader parameter pStreamReader.
dim vLine as string = pStreamReader.ReadLine
dim vFields () as String = vLine.Split(","c)
Well ... obviously the split does not work with embedded commas in a field. Looked at TextFieldParser, but it is in the FileIO class and the module is passed a IO.StreamReader. Can it work?
Or how abour a RegEx? Does anyone have any suggestions? I have look around on the internet and it seems like a common questions with a bunch of wild goose chases.

I am writing a VB.NET application which needs to extract data from an XML document. The Dataset.ReadXML function would be suitable, if the XML document was held in a disk file. However I would prefer the XML document to be passed via a string property of my class object, not as a disk file.
Is there a way to make the ReadXML function take its input from a string instead of a file ? If not, are there other functions which can be made to parse XML which is held as a string.?
