My project needs to read and count the individual characters in a textbox. Is that possible? If so, how so?
Nameone = TextBox1.Text.ToLower
For F = 1 To Nameone.Length
L = Nameone(F)
[code].....
Does anyone know how to read individual lines off of a text file?
If the textfile looks like this:
Text1
Text2
Text3
Text4
You could make it so on timer1 it sends text1, then on the next tick text2, and so on?
It's a list of computer systems, basically, that the user can purchase.I need to read this file, line-by-line, into an array. Let's call this array csvline().The first line of the text file would stored in csvline(0). Line two would be stored in csvline(1). And so on.(I've started with zero because that's where VB starts its arrays). A drop-down list would then enable the user to select 1, 2 or 3 (or however many lines/systems are stored in the file). Upon selecting a number - say, 1 - csvline(0) would be displayed inside a textbox (textbox1, let's say). If 2 was selected, csvline(1) would be displayed, and so on.
It's not the formatting I need help with, though; that's the easy part. I just need someone to help teach me how to read a CSV file line-by-line, putting each line into a string array - csvlines(count) - then increment count by one so that the next line is read into another slot.So far, I've been able to paste the numbers of each system into an combobox:
Using csvfileparser As New Microsoft.VisualBasic.FileIO.TextFieldParser _
("F:folderprogramnameprogramnameinDebugsystems.csv")
Dim csvalue As String()
[code].....
But this only selects individual values. I need to figure out how selecting one of these numbers in the combobox can trigger textbox1 to be appended with just that line (I can handle the formatting, using the string.format stuff). If I try to do this using csvalue = csvtranslator.ReadLine , I get the following error message:"Error 1 Value of type 'String' cannot be converted to '1-dimensional array of String'."If I then put it as an array, ie: csvalue() = csvtranslator.ReadLine , I then get a different error message:"Error 1 Number of indices is less than the number of dimensions of the indexed array.
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.
So I have a code atm that has 2 combo boxes, one to select the make, then it will enable the model, I have 3 model choices, here's code: [code] Once I have selected my model of the car, it takes me to that specific form with a picture of that model, I then want to display individual parts, with individual prices that will add up in a text box above.

What is the best way to read a CSV file that contains quotes within fields?I was doing something like this but it is too hard coded it would seem.[code]
View 4 RepliesIs there a way to handle quotes with a field in text tab delimited file example:"This program works "really" nicely and is helpful" my reading and understand thus far is that while the file is tab delimited fields can also begin and end with quotes. Therefore is a field contains a quote it gets interpreted as end of field.[code]

I'm trying to read a binary file from a FileMaker 11 container field using Filemaker's own ODBC driver. I was able to write files to the database and this works fine. retrieving them manually works fine and the files look OK and are not corupted. However when retreiving them using VB.NET, and if the file size is approx > 5MB, I get the following "uncatchable" error (yes thats right, I cant "Try Catch End Try", it just crashes):
System.AccessViolationException was unhandled

I'm working in vb.net creating an asp.net web application. I have an SqlDataSource and a GridView on my page.
I want to change the DoNotMail boolean value represented by a Gridview checkbox and automatically update in the database if the checkbox is checked from 0 (False, Will Mail) to 1 (True, Won't Mail) here is the code I used. [code]...
is it possible to do a two way sync on the entire gridview when the user hits a button so you don't have to do an update every time a row is changed? because the user might check the box and then check another box then uncheck a box and it would be a lot of updates...

View 3 RepliesBasically I'm designing a program atm for my college coursework and have been trying to get a search button to work. Basically, I need a way so that after the customer id has been found, my variable (in this case inc) needs to set itself to the row which the customer id that has been found is in. the idea is that it finds the row, and fills in the textboxes which I have with the data Here's the bit of code I have atm: (And btw, inc is set as an integer earlier on in the program)
Dim CustomerID As Integer
'asks for the customer's ID number so that their results can be found.
CustomerID = Val(InputBox("what is the Customer number?"))
Try
Sql = "Select * from tblQuotes WHERE CustomerID = " & CustomerID

Hopefully with the text Whatever the Row Number is being replaced by actual code to get it to that row.

I am making a HTML editor and thats the easy par ie saving as .html etc, but i want to also add in the thing thats in VB wherein it picks up the word your typing and make suggestions, i have made it so it can have a data base of a thousand words (1000) and you can add and it loads all fine. Now i need to add in the functionallity to read every Key, i tryed
Code:
If e.KeyCode = Keys.Space Then Scan = ""
But none of this works, is there a better way of getting the the key press and adding it to a string untill space is pressed in which the array is cleared.
Code:
Imports System.IO
Public Class Form1

So say i had a Tag stored that was "HTML" then as soon as i pressed the < key it would start checking my keys then if i pressed H it would display all word is the drop down box with H at the start then if i followed it with T then M it would show HTML in the box and maby a couple of others that began with HTM, if i then hit enter it would add in the L> thus compleating it and printing "<HTML>"

View 1 RepliesI am very new to VB, and am programming in VB 2008 express. Sorry if this thread is in the wrong spot I need to add two 40 digit numbers together and was thinking that the simplest way to do it would be to input them as a string and then convert the string to a single dimensional array where x(1) is the 1st digit in the number, and x(30) is the 30th digit, etc. I would do the same for the other number where y(1) is the 1st digit. I would then add the x(40) and y(40) (which are the last digits of the number) together and carry the remainder into the next addition (39th digit, 38, ...)

View 2 RepliesI have a vb.net project that loads "plugin" dlls at runtime to crunch some data in slightly different ways and return the results. To do that, all the plugins implement the same interface, so the GUI couldn't care less how the plugin arrives at its final dataset, just so long as all the plugins deliver it back to the GUI in the same way.
I'd like to set up per-plugin options in addition to the main program options. I have an options form that accepts an object of type System.Configuration.ApplicationSettingsBase and displays the contents in a PropertyGrid control, so it'll show any My.Settings object the same way. Question is, how do I pull the My.Settings object out from a plugin that's loaded at run-time?
