I have to work with network program with vb 2010. I'm trying to show the ReadLine stream in label text but it won't show.
Dim tcpCli As TcpClient = tcpList.AcceptTcpClient() 'claiming tcp listener to accept the tcp client
Dim ns As NetworkStream = tcpCli.GetStream ' assign ns as network stream and assign as client to get nw stream
Private Sub runExe() Dim myProcess As New Process() Dim myProcessStartInfo As New ProcessStartInfo("mkclean", " --optimize """ & txtSrcFile.Text & """ """ & txtSaveFile.Text & """")
Am I being dense here? StreamReader.ReadLine states that: A line is defined as a sequence of characters followed by a line feed (" "), a carriage return (" ") or a carriage return immediately followed by a line feed (" ")
i have a loop in here what suppose to add a rondomly choosen number and show it on the label .text increase every time by the the same number when appear. It does not do it correctlythat is the
Private Sub licz() Dim pbs() As PictureBox = {PictureBox1, PictureBox2, PictureBox3, PictureBox4, PictureBox5} Dim las() As Label = {Label1, Label2, Label3, Label4, Label5, Label6, Label7, Label8,
When I read a text file as the code below the first line returns as nothing. I checked the text file and it contains 3 lines before the read. After the read the first line is blank the following 2 lines have values.
When the form load I needed to create a text file into "C:\Program Files\User\User.text" But if the file exist it will read line1, line 2 and line3 of the text in different textboxes Then if I click save, it will write textbox 1 to line 1, textbox2 to line 2 and textbox3 to line 3.How do I do it?
The end of the text document my application is reading is denoted by a character that I cant identify, copy or paste. I attached an image of it so you can see. I have no control over the formatting of the document so I can't change the character. During debugging it shows the same character as shown in the picture, but if I hit the little tack next to where the variable shows then it changes to "f". However, if I try to see if the variable equals "f" it returns false.
is it possible to show a figure in one Label in another label through a button click event? for instance, i have a figure in label1 and i want to display that figure in a label of another form is it possible?
I need a bit of advice. I am working on my project with the listbox. I know how to create a source to get the strings from the text file using ReadLine method, but I have no idea how to split the strings in the text file by on the third commas and ignore the other strings while select with the matched strings on the listbox for each row.Here it is an example listbox Here it is an example items on the listbox
random item 1 random item 2 random item 3 random item 4 random item 5
And here it is an example text file.
example strings one, any strings 1, any random strings 1, other strings 1, final end of strings 1 example strings two, any strings 2, any random strings 2, other strings 2, final end of strings 2 example strings three, any strings 3, any random strings 3, other strings 3, final end of strings 3 example strings four, any strings 4, any random strings 4, other strings 4, final end of strings 4 example strings five, any strings 5, any random strings 5, other strings 5, final end of strings 5
The listbox is display the list of an example items, so if I select the "random item 1" item on the listbox, it read the strings through in the text file on the first line to get the strings on the third commas in the same line which it is (any random strings 1) to split it while ignore the other strings (other strings 1, final end of strings 1) that come fourth and fifth commas. So, if I select the "random item 2" item on the listbox, it read the the strings through in the text file on the second line to get the strings on the third commas in the same line which it is (any random strings 2) to split it while ignore the other strings (other strings 2, final end of strings 2) that come fourth and fifth commas and so on...That is what I am trying to achieve by select the each listbox item to get the correct strings for each line in the text file that come on the third commas while to ignore the other strings.

Basically I would like to read in this file line by line and separate every every field into a custom variable and then do some processing. So, I would read in the first record and put the data into these fields

I started coding this using a TEST file that only had two fields name and a number
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click 'Dim FILE_NAME As String = "C:aaple2.txt"

I got an unhandled exception on this line: mNum = objReader.ReadLine
I have a form that I am loading text (strings) from a database into a label.text (so the text from the database shows up into the label) I have done this code in a class that keeps all my database stuff seperate.
Public Function getQuestions() As List(Of String) Dim question As New List(Of String) objConnection.Open() objReader = objcommand.ExecuteReader
[CODE]...
Within the form that the label is in I have done this code
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Label1.Text(db.getQuestions().ToArray) End Sub
I am basically making a quiz, so that when the form loads, question 1 is on there is 4 possible answers. You then press next button and it goes to the next question.

Is there an effecient way to give one label the ForeColor, BackColor and Text of another one of 3 possible labels? I need to do this frequently for a dozen labels in a windows form.
I am using a label to display a song for an mp3 player. I wanted to scroll the text inside the label for anything that is longer than the label width. I figured out the width of the label and if the width of the text inside the label is longer. But I have no idea how to turn this into subtracting parts/pixels of the text currently displayed and how to append the subtracted parts to the end of the new text.
Sub f1timer2tick() Dim g As Graphics = f1l2.CreateGraphics Dim s As SizeF If f1l2.Text.Length > 19 Then
basically i need to change the text of a label where the name of the label comes from the value of a variable.So, for example,
Dim x as String = "lblTarget" Dim y as String = "Target Text"
In this case the text of "lblTarget" would need to be come "Target Text". Basically, the label that is named the value of variable x would need to take on the text of variable y.
Is there any way to detect if the text in a label is longer than the label itself (assuming autosize is set to false)? I want to trim the text in a label so the last line is a finished sentence (everything after that sentence is removed). I hope you understand what I mean.
I want to go from this:"Hello. This is a test string. Most test stri..."
I have another probably easy question to answer but i can't figure it out... I have made a little snake game with a score attached to it running through a timer that outputs to a label.
I need to format a Label to show numbers in a certain way. I had asked this before about textboxes so I looked into that first but it didn't do what I wanted.
Im working on a project containing a couple of forms. On the main form I want to labels in the status bar that show the X,Y location of the cursor when it moves over the form. I thought this code would do it but it doesnt work
