I'm having trouble reading in the file and populating the textboxes accordingly. After loading the file (I think that is) nothing is being populated in any of the textboxes listed below. Basically I'm not sure if the file is being read or not.
If OpenFileDialog2.ShowDialog() = DialogResult.OK Then
If My.Computer.FileSystem.FileExists("path_to_file") Then
Dim ioFile As New System.IO.StreamReader("path_to_file" + "filename")
TextBox1.Text = ioFile.ReadLine() 'Adds the first line
TextBox2.Text = ioFile.ReadLine() 'Adds the second line
TextBox3.Text = ioFile.ReadLine() 'Adds the third line
TextBox4.Text = ioFile.ReadLine() 'Adds the fourth line
TextBox5.Text = ioFile.ReadLine() 'Adds the fifth line
End If
End If
I just wondered if it is possible to save multiple text boxes as one file.Currently I:
a ) haven't woked out how to save a TextBox atall and have had to use Rich Text Boxes for this purpose and have used: RichTextBox1.SaveFile("Something.txt")
b ) Haven't worked out how to save/open files as one file. I have had somebody suggest to me using Arrays but I do not know what this meens
I got a problem about the arraylist function. Now I want to create and return an arraylist with each student ID for populating listboxes. Public Function StudentIDs() As ArrayList End Function To display the student ID in the listbox by calling this function. (I need to read student information from text file. There are 6 student, so the result should be 100,101,102,103,104,105).
this is probably a bit tense and I'm not sure if this is possible at all. But basically, I'm trying to create a small application which contains alot of PowerShell-code which I want to run in an easy matter.
I've managed to create everything myself and it does work. But all of the PowerShell code is manually hardcoded and this gives me a huge disadvantage. What I was thinking was creating some sort of dynamic structure where I can read a couple of text files (possible a numerous amount of text files) and use these as the source for both the comboboxes and the richtextbox which provovides as the string used to run in PowerShell.
I was thinking something like this:
Combobox - "Choose cmdlet" - Use "menucode.txt" as source Richtextbox - Use "code.txt" as source
But, the thing is, Powershell snippets need a few arguments in order for them to work. So I've got a couple of comboboxes and a few textboxes which provides as input for these arguments. And this is done manually as it is right now. So rewriting this small application should also search the textfile for some keywords and have the comboboxes and textboxes to replace those keywords. And I'm not sure how to do this.
So, would this requre a whole lot of textfiles? Or could I use one textfile and separate each PowerShell cmdlet snippets with something? Like some sort of a header?
[Code]...
Now, this snippet above lets me either use a text file as a source for each username used in the powershell snippet. Just so you know :) And I know, this is probably coded as stupidly as it gets. But it does work! :)
Im just pulling information from SQL and populating textboxes etc.My question is firstly i have an issue because i can figure out how to do it, and secondly is there an easier way of writing this.So my Issue, i wrote a function to connect to SQL and pull information back which is fine it fills DS(Dataset) and then i want to be able to assign the relevant information within the DS to the desired textboxes,
Have a main form with textboxes on it. When the user clicks a hyperlink on that main form it pops up a new form that they drag and drop files to either a listbox or textboxes, that part works fine. All the seperate form is doing is simply grabbing the filename to bring back to the mainform. That is working correctly. What it is then supposed back on the main form is read the files, again the reading part is working fine, based on the read it's supposed to populate the textboxes on the main form. When I have the listbox that the user drops the file into on the main form rather than a seperate form it works fine, form size limitaton and aestetics are why I'm using a seperate form. When I debug it it's working fine, I can't figure out where it's dropping the info because line by line it does everything right and it shows the values in debug correctly, however when the main form regains focus the values do not appear as they would if I loaded the file directly into that main form.
I am having trouble with .net again. I have a series of 10 text boxes. I want to be able to populate them from an array and read there values into another array. In vb6 I would create a text box array with 10 text boxes / indices. I could then populate them by txtbox(i).text = arrVal(i) and to reference them arrVal(i) = txtbox(i). I am stumped I can create 10 text boxes on a form if I have to, but I want them somehow tied to each other as they were in vb6.
I'm trying to populate textboxes on one form based on a selection on a combobox on another form. All data will be pulling from the same SQL table. I've got the combox to work fine to show the correct data in one of the textboxes by using the lines:
Dim connectionString As String = "Data Source=F03D3S-DEV01; Initial Catalog=dos_track;" _ & "Integrated Security=True"
[Code].....
,but not sure how to get the other textboxes to fill with the correct data (from the same SQL table row) associated with the combobox selection. I've spent SO MUCH time on this trying to figure it out, but am getting nowhere fast...
this is how I set up my data object for a file parser. (
Dim mytable As New List(Of String(,))() mytable.Add(New String(4, 16) {})
and it loads mytable like this:
mytable(x)(y, i) = sToken(i)
Let me explain the indices, I have a form with a tab control. In mytable,x is the tab number. Each tab has up to 5 groups which is y. Each group has 17 text boxes, i.Each group also has 17 labels.I started looking at Me.controls, and looking at control properties like tabindex for some way to iterate through the textboxes and mytable to load the textboxes.
so I started with:
for x = 0 to 31 msgbox(group1.control(x).text next x
and I saw how all my objects are not in sequence as it descending halfway through my label controls, then switched to my textboxes, and then seemingly finished randomly. I am at a total loss without the old index property and what I want to do is something like (forgive my syntax)
To me this is fun and challenging, but also very frustrating and makes me miss coding in assembly As I can't seem to find any reference to the tree structure of accessing components indirectly, if that makes sense.
Ok so i have a text file with 20 lines (one word each line) and a for loop that runs through those 20 lineI have a string array, a random, and an integerwhat i am having problems with is having the program read from a textfile then having a random chose a random number then assigning the integer that random number then having a textbox equal that word if you get what i mean..here is my code for that
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged Dim AIWords(19) As String
I have a database with table "Customer" that will be the datasource for my form controls. My form has a combobox and various textboxes that need to change based on the selectedvalue in the combobox, cboCustNo. Firstly, I'm try to get the combobox to populate with the customer names on the table but have the value member of the combobox set to their customer numbers (just for ease of indexing). Based on the user's selection I'm trying to have various textboxes show the corresponding data (Address, City, Balance, etc.). The code I have so far is below:
Dim cnnDB As New Data.OleDb.OleDbConnection Dim cmdSelect As New OleDb.OleDbCommand Dim rdCustomer As OleDb.OleDbDataReader Dim CustTable As New DataTable
I'm making a personal program (So it doesn't have to look nice or be super sleek) that is basically an alarm clock. I set the time and date, it writes it to a text document then it reads it from the text document back into another textbox that is hidden and compares it to label1.text which is my system time and date.the problem is, I have it so that I can add multiple dates in one document so when I enter one it'll do as so [code]how can I make the program read 1 line, wait for it to match the label, (I already make it display a message box) and then after that is all done, go to the next line and wait for it to match. etc etc.
Can anyone tell me why this code isn't working? I am trying to read a textfile into a textbox with multiline = true. All i get is the first member of the list from the textfile. The rest is left blank.Public Class Form2
im myLines As New List(Of String) Dim index As Integer = 0 Private Sub btnLoad_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
How Can I make my textbox1 show the continents of a text file but I do not want it to show it right a way I want it to write one character at the time like typing it.
I have a problem with reading data from a textfile called RESORT.TXT
Barb Allen 604 777 1234 2008/12/01 2 3 1 3 D
I can't seem to figure out the datatype for the phone number? It displays in my listbox, but I only recieve the number 6 and the not the full listing of the phone number 604 777 1234.
I can retreive all items in my notepad but when I am adding them up in my listbox, and trying to print them in the console. I can only display two strings. I don't know why. My string is a combination of a name, space & score. ex: "luke 300". That is the pattern of all strings per line in my text file. I am separating the name and the score using space as the indicator. When ever a space is found, string before and after the space is retrieved and added to the listbox
Here is my
scorelist = New ArrayList reader1 = My.Computer.FileSystem.OpenTextFileReader(My.Application.Info.DirectoryPath & "scores.txt")
i can anyone tell me how do i save the below codes into textfile and make my program read from it? i'm trying to make a chinese calendar and below are the months of it. i'm gonna need to save up to about 3 years of months.
I've setup a TextWriterTraceListener which outputs the debug messages I've written to a file.This works fine however what I am trying to do know is output the content of this file to a textbox using a streamreader object.I originaly thought it may because I did not set the text file to allow read/write access so I changed this by setting the following:[code]
I'm currently use visual basic 2008. The problem is I have try this code but,it produce no output. There is no problem with the code I guess. Here is my code
Dim i As Integer = 0 Dim line As String 'Dim reader As StreamReader = New StreamReader("C:\drill.txt")
I have a bar cash register and have buttons for the drinks and number pad. In the program I have it working and it is reading the File and storing it in a Array. the problem i have is writing back to the part of the textfile. Here is 2 of the drinks buttons, all the rest of the drinks are the same.
Now I want that presented in the listbox with the semicolon and it should be aligned per column so that the numbers, the names, the prices and the quantity are exactly aligned per column.If I read the file like this:
[code]...
Then the semicolon is not presented in the listbox and I don't have any alignment per column. As the names of the woods are not equally long the prices and the quantity are not aligned directly below each other...
My questions are:
1) How to add the semicolon in the listbox as seperator of the columns
2) How to align the 4 columns in the listbox (as I have an array Item(3) )
Later on I need to be able to change the quantity (last column) from 0 to > 0 (that's why I have to use an array)
I'm still at it.Have a new delima I have a form with 5 textboxes.1 thru 4 are read only ,and display various data recieved during my process. #5 is a user input,and accepts only numbers. Top Speed.bmp
[code] My question being what determins the order that the textboxes are read. Example I have 4 textboxes named textbox1 to textbox4 When the code is run the output in richtextbox1 is textbox4textbox3textbox2textbox1. The output in richtextbox2 is 4321.So here textbox1 = test(3) and textbox4 = test(0)
How can I read data from textbox1 to....n using cycles? Something like this: 1. For n=1 to 50 2. text=textbox_n.text 3. Output=output+text 4. Next 5. Msgbox(output) The question is in line 2. Syntax "textbox_n.text" is not right. How is it possible to read from textboxes using cycle and variable n?
I am starting to learn reading and writing to textfiles. One quick problem. My code here
'Read is the variable that will read the kp.txt file" Dim read As IO.StreamReader read = IO.File.OpenText("C:2/kp.txt"[code].....
however when it is read into the listbox those 3 words appear on one line in listbox How can i make it so that each line of the textfile is placed in each line on the listbox?
I'm making a program which has 7 textboxes. I intend the program to be used for classes in school, so the text would be like 2D Art, Geology etc... whatever your classes are. I have figured out how to use the streamwriter to take the text in the textboxes and write them to a .txt file however, my issue is with loading the text from the .txt file back into the textboxes. I did figure out how to write it so that all the text in the .txt file is loaded back into textbox1 but I have 7 textboxes... Here's the coding for the Load button:
Private Sub Button46_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button46.Click Dim MainWindowLog As String = "V:Users(O.o)~(--_--)~(o.O)DocumentsVisual Studio
