View 5 RepliesReading Name And Numeric Data From Text File
Apr 27, 2012I'm working on a program for a side business I run with a friend, who is a non-programmer.I've done a program before, using IO.StreamReader and IO.StreamWriter to read and write lines to a text file.
But now, I'm working on reading text data (it's output from an old legacy program) that reads a first and last name, and the customer number (6 digits) from one file.
Then, it uses the data (customer number) read the first time to cross reference the zip code and status from a second file, and display it.
The Data in the Text Files are as follows:[code...]
How would I begin parsing for the first and last name, and the customer number to assign to different variables?In the line that references names.txt I meant to put customers.txt.

VS 2008 Read Csv File Into Dgv - Text Versus Numeric Values?
Oct 13, 2010I read a csv file into my .net program using ado.net and display it in a datagridview.In the file I have two rows. The first column is a component id, and it is supposed to be numeric. But the user can edit the csv file before having my program load it, and accidentally put text there. That is something I want to edit when he presses a button to add the data to the database. So let's say he puts a value of A in the first record and a value of 1 in the second record. Or vice versa. What is displayed in the dgv is a blank in the first record and a 1 in the second, or 1 in first and blank in second. If both csv records are A, then what is displayed in the dgv is an A in both the first and second records. I don't understand what is happening. The fact that there sometimes is a numeric in the column makes it think it is a numeric field and therefore only display numerics and blank otherwise, and the fact that there's always text in the column makes the code know it is a text field?

Import Numeric Data And Export It To Various Text Files Using Ascii Templates?
Feb 27, 2009I am developing an app that will import numeric data and export it to various text files using ascii templates. I am basically converting the template file into a single string, replacing application fields in the string with {0}, {1}, etc... and adding the result into an array that is then passed to the String.Format(str_Template, Params()) to provide the final output. I have set it up so the template will use the standard VB.Net formatting syntax.
A simple template example:
{<prt_Mark>:G} {<prt_Qty>:F2} {<prt_Length>:F2} {<prt_Remarks>:G}

both 1 & 2 the above strings are fictitious (i made them up to make my point clear)

I will then confirm the (2) from the client.

Numeric And Non Numeric Data?
Jan 22, 2010I am reading a data file and storing them in an array of string.Data is random, could be like "1","2","133,18" but sometimes there can be missing values like "?".Once I load the data in the array, I want to check if at least a majority (like 60% of them) are numeric values.If yes, then I wanna track down the higher and lowest value in the array, and output a range of 5.Loop through the array
If 60% of them are numbers (integers or decimals) then find highest value, find lowest value end if produce range
If for example lowest = 1 and highest = 100, range of 5 means 0,20,40,60,80,100 (so 5 ranges are 0-20, 20-40, 40-60, 60-80, 80-100).Also if the ranges turn to have decimals due to weird numbers, I would like to round them up.My problem is, in order to find highest and lowest when there are non numeric values in the array like "?", how should I handle those? I was thinking of something like Double.NaN but I would have to have an array of doubles.

View 13 RepliesOne Sub Procedure / Change Text Color In Rich Text Box / Without Button Handler?
Oct 8, 2010everyone! I've been at this for a while, and I'm not sure how this issue can be resolved:I'm working on a project in VB.Net, and I have a form with a rich text box. I have a groupbox with 4 radio buttons inside that are intended to change the font color of the text. Coincidentally, I have to repeat this same functionality for a 2nd set of radio buttons that would change the text font family.
At any rate what I've only been able to do is the following to successfully change the font color of whatever text I highlight in the rich text box:
Private Sub rbtnBlack_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rbtnBlack.CheckedChanged
rtbxTextEditor.SelectionColor = Color.Black
End Sub
Private Sub rbtnRed_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rbtnRed.CheckedChanged
[Code]...
Is there a way that I could write a sub (I'm assuming I would use a sub, since I don't think I need to return anything, thus eliminating the use of a function) that would handle the action of changing the selected text color in the rich text box without having to use a separate sub for each radio button? Mind you, per my teacher's specs, she doesn't use a button handler for any of this.
Pan/change/move The Text Appended To A Richtextbox Control So The Text Itself Scrolls In Addition To The Scrollbars?
Jul 11, 2011My application appends incoming report data onto a RichTextbox control. As more text arrives from an external device, the thumb initially fills the trough and as times goes on, the thumb diminishes in size. This is expected behavior.A modal dialog box allows the user to cancel the file download but since it's modal, the user can't scroll down to see what the last text that was appended.Is there a property/event/method that will show the most recent/last text in the RichTextBox control, rather than the initial text as I have it displayed now? The user would be able to see the text drawn real time without having to use the thumb to accomplish
