Displaying A Line Of Data From A CSV Txt File In To A Listbox?
Dec 13, 2011
I have a .txt file that I need to be able to search from a text box, and then display the results in a listbox. Each line is formatted as the following.Jim Wells,1/12/85,3,999-555-4562ith the textbox I need to search the file for the third value (in this case the 3). But I need to search all lines of the file, and any line that has a 3 or whatever number is searched in the textbox needs to be displayed in the listbox in this format.

I have some numbers stored in a notepad and i want to display them line by line on a form that has a label or textbox whenever i click a commamd button. These numbers should display one after the other rapidly and should stop run whenever another command button is clicked hence the lucky is seen on a label or textboxes, is just like a raffle.

I am using VB2008 Express. In my program I have a loop that is updating variables. As these variables are updated, the updated information must be displayed in the RichTextBox. Everything works fine and I can display my first line of data, but then the next time the second line of data overwrites the first line. I would like each update to be on a new line, so I need to force a new line in my code. Here is the code for part of the loop so far.[code]

I'm trying my best to learn Silverlight/WP7 but it a steep learning curve, coming from winforms/CF.
I'm trying to fillout a listbox from a collection but it does not display anything and I'm not sure what I'm doing wrong.
I think the Items Collection (JobCollection see zip) is getting added to the itemssource property but nothing is displayed.[code]...

I have a form displayed where a user can can select a 'function' from a list box. That 'function' has a corresponding ID number which I need to be able to take and use later in the code.The List of functions is preset (about 150+ them and the IDs are already assigned (so I can't just use the index).So if the user selects "Function A", I need the code to set a variable to, for example "42" (or whatever that Funtion's ID is).
I was going to do this using listbox.item and listbox.itemData, but I'm using VB.Net in VS2008 and I understand that function is no longer present (to add ItemData at design time).Here's where it gets complicated. When the form loads it looks at the variable containing the FunctionID and if there is one present, I want it to populate the co-ordinating FunctionName. I can do that if I know the index number, but I don't know how to look at the FunctionID and return it's index (all FunctionIDs are unique).
A) store the info, either in the Listbox using ItemData, in an array (but I'd prefer to do it at design time), or some other way you might suggest.
B) cross-reference the ID and display the name in the listbox when the form loads.

I'm trying to read multiple values from a registry subkey in the CurrentUser key. I need to display these values in a listbox with multiple lines. I so far can only get one of the values from the subkey. I know (or at least I think I know) that I need to list the values in a string (with a possible loop), and then just display the string to the listbox. The subkey is the TypedURLs under CurrentUserSoftwareMicrosoftInternet Explorer Typed URLs. Here is my code I have so far (I did a year of basic VB as part of my Uni course).[code]

I've been writing a weight program for flooded pressure vessels and I'm having trouble retrieving the data from the text files I've been saving. I know how to write the data to the text file, but retrieving it with OpenFileDialog is not so easy for me.The user has individual text boxes that they input strings or numbers into and when they save the file, each text box input is written to one line in the text file. For example, the first text box is for the username, therefore the first line of text that is saved is the person's name, the second text box is the customer, thus the second line in the text file is the customer name, and so on.
(Actually, the first line of text in the saved file designates whether English units were used or Metric units because when the user retrieves the saved file, English units will open one form and Metric units will open a separate form, so some If...Then statement will need to occur).I need to be able to read the first line, have either my "EnglishForm"form open or my "MetricForm" form open, and then have each subsequent line of text be displayed in their corresponding text boxes. I know I need to use ReadLine or LineInput, but I don't have a clue what to do.Assuming the syntax I've displayed below would just magically work (if only life were that easy), it would look something like this
If FirstLineOfTextInFile = "English" Then
EnglishForm.Show()
ElseIf FirstLineOfTextInFile = "Metric" Then[code]....
And so on...I read a lot of articles from the MSDN library and exhausted each link that I've looked through from Google and Bing, but most only retrieve data from the file to a single text box through some loop or streamreader and don't take into account multiple forms.

I am trying to read a line from a file and add it into a listbox. The SelectedIndexChanged event of the listbox places the selected item (hence, the item I added from the file) into a variable that is declared as a Store (my own personal class.) I can easily add the line from the file into the listbox, but I run into a problem with the SelectedIndexChanged event. When I click on the item in the listbox, I get an error that says "Unable to cast object of type 'System.String' to type 'WindowsApplication1.Store'." (I guess this is because I added an item to the listbox that is from a file.) I tried a variety of methods of casting, but nothing seems to work. What can I do to fix this?
