I'm working in this application in Visual Basic Studio 2010 I have a combobox where user select phone model and textbox where a text file is loaded when user select model, I added text files to the project resource because I don't want to put them in files in the root directory of my application
[IMG][/IMG]
what I need is a code to make text box load the text file wich have the same name of selected in combobox for example when user selct : CT-810 in combobox the text file with name: CT-810 must be loaded in the text box and so on for other combobox records
I have many text files in a folder. What I can do now is to read through one text at a time and insert it into the database. My little app reads a text file when I debug it. So, I need to run it several times to read all those text files and import them into the database.
My question is how to read multiple text files inside a folder at a time. Here's my code which works fine but it reads only one text files at a time.Private Sub btnRead_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRead.Click

I need a way to loop through a folder and check if there's text file. But I cant get it right. Can anyone show me some code or links ? I'm using VB.NET, .NET 3.5
creating a function that reads in data from multiple textfiles into a combobox. The function just needs to read line 1 into from every text file into the combobox.

I am making a recipe book that calculates the amounts of each ingredient needed for a dinner.The user inputs the number of people they are cooking for and then my program works out the amounts of ingredients needed, simply by * number of people.I know how to read from text files using commands such as: My.Computer.FileSystem.ReadAllText()But does anyone know how to take text for a text file, then multiply the contents of that file by the number of people?The text file only stores numbers, but I want to multiply each line seperately..Instead if getting the result of 10050*3, I want 100*3 and 50*3 on a seperate line.[code]For this to work, I suggest downloading the full project.You will also need to create a folder with two text files inside it. This will not work without them. "QuantityList.txt" and "IngredientList.txt".
View 17 RepliesI'm trying to implement Bandwidth Total calculation into my little desktop monitoring program using 2 *.txt files. Everything else is working great except for the writing/reading part of it. I had put this together originally without the intention of bandwidth monitoring, but I've decided it would be a good thing to have.I want to have 2 monitoring types: Windows Session Bandwidth Total & All-Time Bandwidth Total (since the program was 1st run on the machine). The counter is on a Timer (2nd of 2), and I want it to write and add the label values each second into the file, then when Form3 is opened, to read the text file and show the results.

I'm having a problem where instead of reading a text file from the location string, I changed it to read the text file from the resource location and it breaks my program. I've also used the insert snippet method to get most of this code, so it is safe to say I don't know what is going on. [code]

View 1 RepliesI am witting an app that will generate batch files to do an unattended installation of a share point 2007 farm. I already have a batch file I use and it's pretty big. I copied and pasted the content into my application, and I'm using the System.IO.StreamWriter to write to the batch file from the winform. [code]As you can probably guess, I'm doing all of this in my mainform code window. There are maybe 3 or 4 batch files that will be generated based on the selections made on the form. For example, I'm generating a batch file to create the OU, Group and service accounts the farm will use in active directory, I'm creating a batch file for all of the variables that will be used for the additional batch files created, etc. How can I split this up? is there a way to create the batch files without having to actually copy, paste my existing batch file content into the mainform code window? I'm using file.writeline on each line of the pasted content by the way.

Im trying to write a loop that will read through a number of *.csv files in a folder and then stuff the data into SQL. The code works and will happily put the data i want for a named file into SQL no problems. So when i had that working i then tried to loop it so that it would do the same for all files in the folder until all files had been done, and not error out if there where no files etc.
Maybe im tired (well, i am) or not had enough coffee but i just cant get this to work, it should be simple - i know it is infact, but its making ME feel simple.i think i should have an integer count in there, but similar examples ive seen dont use one. Also when trying to open the path i get an error at runtime "the path is not of a legal form"
code:
Public Sub ImportCUSTCSVs()
Dim dt As New DataTable()
Dim line As String = Nothing[code].
Im designing a program that will read from various text files (preferably RTF files) and then put them into the RTF box in the program when a button is clicked.
Here is the portion of my code that i am referring to.
Try
Dim fileText As String = My.Computer.FileSystem.ReadAllText("c:\" & selectedHero & ".rtf")
infoDisplay.AppendText(fileText)
infoDisplay.Rtf.Format()
Catch
MsgBox("Selected Hero currently has no File with us.")
End Try
Now heres the problem. In the file i have a few pictures and its formatted and what not. I thought since its a RTF file and the Box is RTF it would auto format.... but anyways. It appears like this in the RTF Box.
{\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fswiss\fcharset0 Arial;}}
{\*\generator Msftedit 5.41.15.1507;}\viewkind4\uc1\pard\f0\fs20{\object\objemb{\*\objclass Paint.Picture}\objw3000\objh3000{\*\objdata
[CODE]...
Ok so im not sure how i can read from a RTF file and put it in the RTF box with the right format....Ive been searching around for a while.
I have a very simple program which simply populates a listbox with a list of files stored in a directory.
Try
lvScripts.View = View.Details
lvScripts.Items.Clear()
lvScripts.Columns.Clear()
[Code]...
However, I'd like to embed these files into the application itself and open them from there rather than from looking at the directory.To this end I've added each of the files as a resource but I don't know how to populate the list view with a list of the text files in the my.resources rather than a list of the text files in the directory.
So in VB.NET I created a resource file called "source.txt" (as its a text file). My program will take in the text in the file, and then compile it into an executable.
How do I access this file which is in my resources folder in my project?
Is there an easy way to edit the code below so that it copes (works the same) if the embedded resource is not a plain text file, but a compressed text file?
Dim tempList() As String
tempList = My.Resources.ENABLE.Split({Environment.NewLine}, StringSplitOptions.None)
For Each strWord In tempList
enableFullList.Add(New Words(strWord))
Next
I have seen System.IO.Compression but can't work out what to do, DeflateStream, GZipStream etc.
I'm working on a program where I've got a WebBrowser control that displays an HTML file from my 'Resources' folder. Like so... WebBrowser1.DocumentText = My.Resources.MyHTMLFile That displays the text from the HTML file just fine, but it does not display the CSS styles or images that the HTML file uses (even though I've added the CSS file and images to the 'Resources' folder as well).

I have a VERY basic knowledge of VB. I'm having trouble figuring out how to read multiple xml files when a user selects them from a listbox. Below is what I have so far. Currently this will only read one xml file. When I change "Dim strDir As String = PlayListBox.SelectedItem" to "Dim strDir As String = PlayListBox.SelectedItems" the code doesn't work.[code]...

1. OK So a while back someone showed me an example for fonts from resources, but I noticed if you close the window that it opens, The entire program shuts down... what can I do to fix it?Also, The fonts are not showing up on all computers, only this one....
2. I am trying to delete a image file, which the program downloads from the internet, and can change regularly, but when I try to delete it will not delete. It says its in use, and I cant figure out where.

Now I need a script to pick all these files data and load it into one file so that I can use this file to insert data into a table using a fast load script i already have.I have a script that will read this file copy it to a new location and archive it.I can use this final file to load my table.But I dont have a script to read all these files and also read the new file that comes in everyday and load it into one csv file.

I need to require the user of this program to select two text files from any directory. I then need to display them in a List View, which I have built. File 1 needs to load into the first column and File 2 needs to load into the second. They will correspond to each other.[code]...
View 1 RepliesI currently have a function that loads an XML and takes all of the nodes and makes an object with them and adds them to an array.I need to be able to now see if there are more than one xml doc in a folder, and if so also add their objects to the array until all of them have been read. How would I go about doing this? I've been searching through the System.IO. to see if I could find something but I haven't been able to yet.

I am writing a VB.NET program and I'm trying to accomplish the following:
Read and loop through a text file line by line
Show the event of the loop on a textbox or label until a button is pressed
The loop will then stop on any number that happened to be at the loop event and when a button is pressed again the loop will continue.
Code
Imports System.IO
Public Class Form1
'Dim nFileNum As Integer = FreeFile() ' Get a free file number
Dim strFileName As String = "C:scb.txt"
[Code] .....
I'm able to read the text file but my label will only loop if I hit the start button. It goes to the next line, but I want it to continue to loop through the entire file until I hit a button telling it to stop.
Is this possible? I have tried a few different methods with no luck. I am more of a JAVA person, but am taking some classes for VB, and have been playing around. This is what I have tried:

I think I'm going about this the wrong way, but would like to know if anyone has achieved this. All I'm doing is printing a simple character map to 255 labels, each label containing a char. Not an assignment, just having fun.
I want to replace the text of my buttons using a loop and I dont know if it is even possible. So here is how it works I have multiple buttons with blank values in them. I also have a database that has a table in it. Now when my form loads i want the buttons to have a new value in them which will come from my table. And I want to do this process using a loop like the code below

I current have an app that I am trying to create. I have 2 List boxes, a textbox, and a command button.What I am trying to do is take about 100 text files that all have certain text in them that I need to change at run time to whatever I put into the textbox. For instance Each Text file has my old company name and I want to be able enter my new name into the textbox and click the command button and the app will open each text file, find the text that I specify and replace it with my new name then save the file into a specified folder.What elements should I be studying to make this happen? So far this is what I've come up with:
OpenFileDialog - to open the file
StreamReader - to read the text files and find the text that I specified
**Not sure on the replace method**
StreamWriter - to write the text from the textbox to the new file
SaveFileDialog - to save the file to the specified location
I am working on a project that copies a text file from embedded resources:[code]This doesn't work.
