I created a telephone number form where the user enters the telephone number in a text box as (nnn) nnn-nnnn. The first 3 digits in parenthesis are the ISD code, the next three are the area code and the last four are the local number. I need to separate out these three fields of the phone number and display in three separate text boxes labeled appropriately. Now, suppose the user enters the phone number in a text box as a continuous string of 10 digits, where the first three represent the ISD code, the next three represent the area code and the last four represent the local number. I'm lost as how to change this string into the form (nnn) nnn-nnnn. This is what I have

Basically what I'm trying to do is read a text file line by line. After each line is read, it will put each line into a separate text box. I've been trying to do this for a while and so far I haven't been able to. I tried using a for loop, but that just put all my lines in to one textbox.

I have a couple of VB6 programs which work 100%, however not under W7, so I need to upgrade them to Visual studio 2008 pro which I own a copy of.The VB6 software used to open a file, read in a line of data and process it then save it in a new file, before going on to the next line input.I need to convert this process to VS2008 pro and can't get my head around it..... getting old you see.I also have a few other needs to do with file handling, but I may be able to sort them myself if I get a start with the above problem....
View 17 RepliesI'm creating a GroupBox at runtime and setting its Text property. Usually, the text is only on one line, but sometimes it wraps. The problem is that the controls contained in the GroupBox cover up the GroupBox's text.
What I'd like to do is determine if and when the text wraps. Specifically, I'd like to determine how much extra height the wrapped text takes up as compared to a single line. That way, I can reposition the GroupBox's controls and adjust its height.
Initially, I thought I'd do this by calling the GroupBox's CreateGraphics() method, and using the Graphics to measure the string. Something like this:
[Code]...
The problem is that the size generated by g.MeasureString(text, grp.Font) doesn't seem to be accurate. I determined that it wasn't accurate by putting enough of a single character to cause a wrap, then measuring the resulting string.
For example, it took 86 pipes (|) to until a wrap happened. When I measured that string, its width was ~253. And it took 16 capital W's to force a wrap - its string had a width of ~164. These were the two extremes that I tested. My GroupBox's width was 189. (a's took 29 and had a width of ~180, O's took 22 and had a width of ~189)
Ok, I saw this code on the net
Dim sFileName As String
Dim srFileReader As System.IO.StreamReader

sFileName = "D:UsersArbenDesktopSerieA.txt"

under the code I pasted at the top, but I get the text on line1 in all labels, like all labels become 1, while the text should be 1, 2, 3 and so on. So anyone can help me do that, each label gets the value of the next line in the txt file
I want to be able to have a dozen or so text boxes be emptied into separate columns in a row of a datagridview. This way the text boxes can be cleared and have new values entered then save the new values as a second row in the datagridview. This is so my VB gui which which runs everything through an old cmd line program, can do batches instead of one run at a time.
The problem is I have absolutely no idea how datagridview works. I've tried searching google and only found some vague things and stuff about databases. I also tried the MSDN library and that was of no help either, couldn't find anything on simply adding stuff and if I had it'd probably be to complicated to be of use to me.

This is the first time I have used a list view control since vb 6, and I have some basic questions.
1) How do I get the listview to show each item in a seperate row?
2) How do I add sub items to the listview?

View 6 RepliesI need to out each line of text to a seperate textbox. or label. Im not sure about a string. Can a string hold a value like, "192.168.1.1 2302"? If so, then how would i output it to a string. If not, textbox or label please. Please keep it simple as possible, since I will probably be needing to repeat this process 500 times, like, a different string for each line, i will have a lot of lines. Dont care about the textbox limit, as long as all the lines are outputted to each textbox.[code]

I'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'm a programming student and a newbie in forums. How can I search for a data in listview from fist form using my second form?For example, I entered 7 entries to my listview, and when I press "Search in listview" button, the second form will open.(My first form contains the listview table and a button named "Search in listview", while the second form contains a textbox which I'll type what I want to search,for example the ID Number, and a button named "Search".)To shorten my code, I like to use from the System.IO Namespace.Is it possible to use System.IO? How? It is frustrating that I can't even find it in Google.
