I'm new to VB.Net. I try to convert from VB6 to VB.Net (2008) with a simple code as shown in the picture below but its come up with Warning. Did anyone know how to solve this warning. Sorry for lame question..
View 3 RepliesI am trying to build a NOTEPAD/WORDPAD like application with vb.net on visual studio 2008.
I need an option to define and choose (MsWord, or CSS like) paragraphs styles, such as: "heading1", "green quotes", etc.
[Code] I want to replace the X and Y column to user enter value. For example If User enter X=100 Y=100. So the text File Should Do changes Like this:
In first line The X and Y should Be replace by 100. For the second line to the 10th line The X should X=X+2.54 and Y remain 100. For 11th line X=100 and Y=Y+2.54. From line 12 to 20 X=X+2.54 and Y remain which is 102.54. The pattern should be continue until end of file. For every 10 line the Y value should change. This Is the code to replace X and Y value: [Code]
code working perfectly for X values. But for Y values for the first 10 lines is no problem but after that the initial Y value is adding by 2.54 and that value should remain for 10 lines only but not for 20 lines.. Actually the number of lines is determined by the user. they need to enter the number of lines. User must decide to how many lines once the changes should take place.
And One more question is : If user enter Row= 2 the changes should occur for two set of lines only. If user enter Row =2 and column=10 So only 20 lines should changes other lines should remain the original value. I attach my text file after the replacement. But the replacement is still wrong.
how I can loop through text boxes.I will be useing several text boxes. Some created at design time and some at run time. The name will be name with a number at the end (MyTextBox1,MyTextBox2)The below code will work for text boxes added at design time but will not take in to account the run time added boxes. Basicly I am looking for that vb6 control array .ubound The other problem with using below code is the boxes are not on the same container.
Code:
Dim Tbox As TextBox
For i As Integer = 1 To 4 'Need a Ubound?
Tbox = DirectCast(Me.Controls("txtMyText" & i.ToString()), TextBox)
MsgBox(Tbox.Text)
Next
So i am count after i find each string example when i find "ADT^A08" it counts how many found in the txt file and then it moves to the next file. My problem is that you can see totalA08 += 1 counts the amount. My problem is that it keeps its old value after each run so the first run counts 5000 and then the next count is 10000. When that last file was the same as the first only 5000. Any ideas on how to properly clear that value after its done [Code]
View 3 RepliesHere is my code for splitting "," from the text file. But the problem is I don't know how to include looping in the code to make the code read the whole text file. when I run this code, it's only read the first line of the text file.
Dim sr As StreamReader = New StreamReader("C:\drill.txt")
Dim data As String()
data = sr.ReadLine().Split(",")

i am trying to automatically generate multiple text boxes on a form with the following code
Private Sub CreateTB(ByVal x As Integer)
Dim y As Integer = 1
Do Until y = x
[Code]...
i need it to generate as many text boxes as the variable x states, so i used the do until loop thing. But i am stuck when it comes to naming the text boxes because obviously all the text boxes cannot share the same name. so i would like to know how to programmatically name each textbox uniquely.
I'm trying to read a text file that contains info like this:
ACX-101-011 , J2168
BTXR-130A-013, D6733
AJ4-233-614, T8211
I want to split each line at the comma and write the left side to a textbox and the the right side to another textbox. I'm close, with the code below, but I can only post results from the first line in the file. How do I loop this and append the text results in each of the textboxes.
Dim TempFile As String
TempFile = "temp.txt"
Dim sw As StreamWriter

I have to save the text boxe values of a form to a text file almost like a data record. I will be saving an Employee First Name, Last Name, Dept Number, and Phone Number. This I know how to do using streamwriter.
next form which we have to use stream reader to load one record at a time. The form has a next button to load the next record. How do I seperate each record (I am sorry for calling it a record if this is inappropriate) when use streamreader and how do I load a record at a time.
I know how to open a file and use streamreader, I just don't know how to read one record at a time and move to the next one.
in a form I need to set the text of labels while looping through a range of dates set by a start date and an end date. Right now I have come up with this code,

View 2 RepliesI've got a button_click function that calls a Powershell script and outputs the results into a text box. This sometimes take a few seconds, so I wanted to first change the .text of the textbox (called Results) to "Please wait... searching remote PC" so the user knows the program is actually doing something.
Results.Text = "Please wait... searching remote PC"
Results.Text = RunScript(LoadScript(fullPCinfoScript))
However, the text will not change. It basically waits to change the text of the text box

I am using a thread to call a process which is spliting a text file into various text file and folder using the system.io , now when calling the Textsplit() with thread on click of a button i am getting the error below , how to use thread and why this error occurs.
Cross-thread operation not valid: Control 'txtbox_destn' accessed from a thread other than the thread it was created on.
I have the following basic code to read a text file from a StreamReader:
Using sr As New StreamReader(FileData)
Dim line As String = String.Empty
Do
'Error occurs on the next line after looping
'past the *last* line in the file...sometimes
line = sr.ReadLine()
'Some code here to parse and process the line
Loop Until (line Is Nothing) OrElse (line = String.Empty)
End Using
I tried changing the Do Loop to Do While Not sr.EndOfStream I tried checking If sr.ReadLine IsNot Nothing and a few other things but I keep getting the Cannot access a disposed object. Object name: 'SslStream' error after all 105 lines have successfully been read and processed. This code has been working for a couple of years, but there seems to be some issue with certain files (recently) that is causing this problem.
I opened the file and I didn't see anything out of the ordinary. No extra blank lines, funny characters or anything of the like. Just a normal file with 105 properly formatted lines. So even know there is something about this file causing the error, I need to obviosly handle this programatically.
What can I do to prevent the sr.ReadLine() line of code from throwing that exception that I have not yet tried?UPDATE Upon reading the last line of the file, the 'EndOfStream' property on the StreamReader goes immdeatly to: EndOfStream: {"Cannot access a disposed object.Object name: 'SslStream'."} It never toggles to 'True'. This makes checking for this condition problematic.
I think I have figured out why this issue only occurs sometimes: if I add in a blank line to the file at the end, none of this ever occurs. It is only when the last line of the file contains data. Still, I should be able to handle this programatically. Telling the vendor supplying the file to always add a blank line at the end should not be the solution.

I am trying to get some text into a text box. If the code had an ID that I could find this would not be a problem, but all I can find is

Is there a way to extract the name out of this?

View 4 RepliesI'm building a program in which it asks for your name and age and determines a ticket price based upon these details. I want it to show the person's name, then their age, (jump down a line) then their ticket price, and then it jumps down a line to show the next person's name, age and ticket price. Issue is, when it's meant to jump down to show the next person, it just completely deletes the last person's details.I'm using this line of code:
TxtFareShow.Text = (Name & Age & vbCrLf & Price) & vbCrLf
How do I fix this?
I'm Making a Simple syntax highlighter and I'm Doing the highlighting in the text Changed event of a RTB and for obvious reasons I can't re highlight the whole document each time someone presses a key so i highlight one line each time the text changes. But this creates a Problem. If someone pastes code into the RichTextBox It only highlights the last Line. So is there a way to get if the user typed the text in with his keyboard or pasted it from the clipboard in the text Changed event?

How do i add these in the different columns so that they are all in one single row.
