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?
View 6 RepliesI am having trouble adding label.text, datetimepicker.text and ComboBox1.Text into listview1 box.I have set up multiple columns, one for the label, one for the date and one for the combo box text. All i have done is:

View 6 RepliesI've been looking through the FCL for a method that will allow me to erase a line of text from a text file and replace it with another line of text. Neither the StreamReader nor StreamWriter have a method for replacing or removing Text from a text file, as does the string object. Are there any available methods for erasing just certain lines of text from a file, and then replacing them with others?
In my code, I'd like to locate a certain line in the text file, and then at that point in the text file, use a For...Next Loop to replace each successive line of the text file with new text:
Dim user_data_file As String = "user_data.txt"
edit_input = New StreamReader(user_data_file)
Dim edit_line As String = edit_input.ReadLine
[CODE]...
However, I can't find any methods that will allow me to do this.
I am trying to print (to a text file) the fragmentation information give by Win32_Volume class using the DefragAnalysis method and have come up with the following VB.NET code:
Dim objReader As StreamWriter
objReader = New StreamWriter(FolderBrowserDialog.SelectedPath + "FragInfo" + "_" + CreationDate + ".txt")
Dim colItemsFragInfo As New ManagementObjectSearcher("rootCIMV2", "Select * from Win32_Volume where DriveType = 3")
[code]....
You do not need to defragment this volume.However executing this in Visual Studio returns the below:
Volume size: MB
Cluster size: MB
You do not need to defragment this volume.The point here is though it does NOT work under Windows Server 2008 R2, but does work under Windows Server 2003 (when executed in Visual Studio), WMI Code will work regardless of platform.

I'm sure there is probably a better way and certainly a more correct way to do with. But, right now when I output to the listbox, I'm only getting the information from the last item in the array.

I'm working on a program that allows me to quickly write database entries. There are 123 columns, almost all of them I'm not using right now so I figured I'd write a program to speed up the process of adding entries to the database.The problem I'm having is exporting every row in a DataGridView to a .sql file. I'm able to do it with a single row but I'm having trouble with doing it for all rows. Every time I get a index out of range exception.I can't figure out why. The problem is probably obvious, but I need a fresh set of eyes to figure it out.In order for it to streamwrite each line it first collects all the data from the columns by using a loop then it writes it, clears the string and starts on the next row, looping for all the data, so on and so forth.
Private Sub StreamAll(ByVal table as String)
Dim TotalRows As Integer = DataGridView1.Rows.GetRowCount(DataGridViewElementStates.Visible)
Dim CurrentRow As Integer = 1

I am stuck on trying to get the sum of numbers to output to a label. I have a label box lblTcost that I would like to have the total of my list box lstCost placed into there. I have tried several things and keeps crashing or just not working at that part. I have used the debugger but since I know the line is wrong any ways that not helping. I though this line would work lblTcost.Text = lstCost.ToString("c") was the proper way but it isn't. Here is my completed code

Anyway I have variable

LblPPG.Text = Val(TextBoxPP.Text) / (TextBoxQTY.Text)
This is the only way I know how to obtain the info I need for this equation but if generated again with no input from the textboxes I get an error. Is there anyway to bypass this if its generated a second time with no inputs?
I have a combo box that has multiple options, when the user selects one of the options (world wide city destinations) a specific value is assigned to a variable. For example if "New York" is selected the variable "x" is assigned the number 155. What I want to do is output the destination that has been selected ie "New York" in a label called "lblOutput1", do I need to store the destination as a seperate variable to be able to produce it in this label as I cannot seem to get it to work:
At the moment I am using:
lblOutput1.Text = "bla bla bla " + cmbDestination.SelectedText + " bla bla bla " + Today()
I've ported a page from classic ASP to ASP.net. Part of what happens in this page is that a collection of custom types is generated and then displayed via Response.Write() commands. I'd like to get the business logic separated out into a code behind file (and maybe move this all into a user control), but I can't seem to figure out how I'd actually display the collection once it's been generated. I want to specify a master page here, too, so the code can't stay inline. Here's a very stripped down version of the current code:
