Read A Text File Into A Combobox?
Jul 25, 2011
I am trying to read a text file into a combobox but for some reason it just wont load:
Dim path As String = "C:UsersLukeDocumentsWhispaServerFiles est.txt"
Dim StringArrayOfBuyers() As String = File.ReadAllLines(path)
Dim clientArray(StringArrayOfBuyers.Length - 1)() As String
[Code]....
So the code is loading the text file fine, it just wont display the first split in the Combobox

I'm using vb.net 1.1 to develop the program. I got text files that contain test result from a machine, like below.
T1 1.24535 2.56335 2.43253 1.24538 2.55619 4.35243
T2 1.42542 1.63728 3.57295 4.59275 1.57320 2.72057
T3 5.12857 2.45375 6.38593 2.58375 3.57259 3.57204
I need to check the test result with the data from database, to find out which test result is failed. If there is a fail test result, I will show an alert to the operator and stop the checking process. Until the operator close the alert, then the checking process will continue from the last read point.

I'm using VB 2010 and I'm trying to populate a combobox with a name followed by a square root, but all that I was able to obtain is a name followed by an image of a triangle with a question mark at the center. I've tried to change the font but without result.

This is the code i have used in Vb.
ChatXml.ReadXmlSchema(My.Application.Info.DirectoryPath & "/../Release/chat.xml")
ChatXml.ReadXml(My.Application.Info.DirectoryPath & "/../Release/chat.xml")
ComboBox1.DataSource = ChatXml.Tables

I've got myself a CSV file with the following contents:
1,The Compact,1.8GHz,1024MB,160GB,440
2,The Medium,2.4GHz,1024MB,180GB,500
3,The Workhorse,2.4GHz,2048MB,220GB,650
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."

Dim number As Byte
Dim name As String[code]............

how to do this for vb6 however i am using vb 2008 and the code for vb6 does not seem to work.
I have designed a form with a text box on it, and a command button underneath. The idea is to run this as a sort of stiky notes section.
I want the text box to read rich text into the textbox (C:\\stickynotes.rtf")
Then i have a command button underneath which i want to save the content of the rich text box to the rtf file (C:\\stickynotes.rtf). This is so that the user can edit and ammend information.
here is some code i have so far
Dim fileReader As System.IO.StreamReader
fileReader = My.Computer.FileSystem.OpenTextFileReader("C:\\stickynotes.rtf")

I need to implement a routine to read a plain text file, BUT that file has a predefined format.The file format is as follows:
Quote:
<FILE_PROPERTIES> 'The "< >" also appears
Propertie1="String" 'It's possible to have spaces after or before the "="
Propertie2="String"
Propertie3="String"
PropertieN="String"
[code]....
Is there any Windows API Routine to read something like that?Or could you point me an URL where something is implemented?I don't want a procedure to read the file line by line and comparing them with Line Input because blank spaces, empty lines and comments starting with " // " may appear too, and I don't want to take them into account, but also I need to save changes to the file, but only to the modified section, without having to read the whole file, and re-write it completely.
Binary access can't work, because I don't know what's the size of each "section", since the number of elements into it can change.
I need something like the "ReadINI" Windows API Procedure, but allowing me to read the "[XXX]" sections headers, and also the "<XXX>" file title header.

Before I begin I would like to mention that I am not a noob in VB, it's just I've never had to do anything this complex before. Basically what I want is to have a program that you can load a txt file in, have it copy key words, and paste it in a textbox so I can use it later on. So in this text file, there is a bunch of info, but I am only needing a certain part. Here is an example of a text file (actually a .dat file, but is easily read):

I am writing a simple program that will encrypt the text that is held in a text box and save it to a text file but I want it to be able to open a text file and decrypt the contents.
Ok now all the threads I have read are about reading a text file that is in a preset location.
