I am simply trying to do this for knowledge sake. I created a simple code that writes(append) to text file whatever the user enters in a text box and click a button.
I am just wondering if it is possible to format the data in the text file?
Example: Add a space between the data being entered every time?
Or draw a line between each set of entries?

Currently, I've used System.IO.StreamWriter to write items to a text file. However, what I have are items separated by a Writeline(). Meaning, the items are displayed in several rows, in a column. But what I want is a single row, with many columns, separated by commas for each item. Example of what I want: 16/8/2010,100,you
vb.net
Dim psBattery As PowerStatus = SystemInformation.PowerStatus
Dim perFull As Single = psBattery.BatteryLifePercent
Dim Now As DateTime = DateTime.Now

View 2 RepliesI've been asked to create a string slicing programme that will take data from a spreadsheet and output it to a delimited ASCII file. The data in the text file follows the structure as shown below:
<time:00:00:00:date:01/10/00:lat:52.34:long:28.30:wind:20:temp:-12recipitation:0.03:visibility:50>
The text file has about 7-8 rows off data following the same structure but with a few changes. So I want to remove the semi-colons from each row of data and format the text file so it has the correct columns on the first row and then the data below but with the long, lat removed etc. However I can't just remove all the semi colons as time uses them.[code]...
I have a problem on how to format my txt file data using VB.

20071016, 444, STANLEY, Dine In, ITEM
Is there any way i can do this using VB.Net?

View 1 RepliesI want to have an output like this in my text file
"30092010_1425","2010/10/30"

I have an application that downloads a .txt file via FTP, and then it calls some sql to insert the file data into my database. I want to check whether the file is in the correct format before trying to insert.
The file should consist of some number of rows, each with the following format:
(4 letter code) (tab) (3 or 4 letter code) (tab) (date as dd-MMM-yy) (tab) (variable length text description) (tab) (1 letter code)
Is there a good way to check whether every line in the file follows this pattern, and warn me if it doesn't?
I'm trying to save a text file with a certain format, kind of trying to create some sort of colums, so when I open it will be easier to read...If I have these four words: Calendar, Car, Time, Airplane; I would like to put them into colums...
vb.net
oWriter.WriteLine("{0,50}{1,10}", "Calendar", "Airplane")
oWriter.WriteLine("{0,50}{1,10}", "Time", "Car")
The problem:When I save it to a text file or print it, it comes out like this:Calendar AirplaneTime CarHow can I put them like "centered", so that doesn't look like that mess...?

I'm having some trouble using resource files. In my project I'm using a bunch of bitmap files and two txt files. Bitmaps are used as backgrounds for controls, but .txt files I want to open in Notepad or WordPad. Till now I was accesing them from a file path on my machine:
ControlName.backgroundimage = New Bitmap(direcorypath & "/Map.bmp")
Process.Start(direcorypath & "/Instrukcje.txt")
And it worked fine. Now I added these files to my resources (it's practical for me to have them in executable file) And replaced those lines with:
ControlName.backgroundimage = New Bitmap(MyProject.My.Resources.Map)
Process.Start(MyProject.My.Resources.Instrukcje)
For bitmap it works fine, but for txt file an error occurs saying that a file cannot be found.
Interestin thing is: when I type "MyProject.My.Resources.Instrukcje" in "Watch" it shows the content of the file. So it is there, only not as a file?
I have to text file in the following format :
Word[tab][tab]Word[Carriage Return]
Word[tab][tab]Word[Carriage Return]
Word[tab][tab]Word[Carriage Return]
I want to get all the words before the tab into one array or to create a new text file and the all the words after the tab into another array or create a new text file too.
Here my function to get the words before tab into an array :
Protected Sub MakeWordListBeforeTab()
Dim filename As String = "D:lao�0001.txt"
'read from file'
[Code].....
I wrote the above function to get all words before tab but I got all the words into array. I've been trying to use the Split method above. What is another method to split those words ?
I know this can be done with regular expression but I don't know regex yet. If you can show me how to get this done with regex it'll be awesome.
I'm returning a database query into a List object and using that list object to fill the X and Y axes of my chart as seen below. (_runData is a "List(of DatabaseTableName)" style Object filled with the results of my query.
Primary_Chart.Series(0).Points.DataBindXY(_runData, "DateTime", _runData, "UPPER_PRESSURE")
My Datetime field is returning as a Serial Number (i.e. 40116.76111) so I want to format the X Axis to display the field more readably. Enter my problem code.

I'm populating a ToolTip with a string of text that has vBCrLf at the end to return a new line.
textfortooltip += dr(0) & dr(1) & vbCrLf
This produces multiple lines in my ToolTip based on a SQL query eg:

Is it possible to format the string so the spacing is a bit more presentable like:
Administrator COMPUTER1
sa COMPUTER1

I was just adding some neat features to my program, and now I realize that they've caused problems with my formatting features. In my program, you can bold, underline, italicize, and strikethrough the text you select. You can also change the color and font of the text. After adding in the ability to change the font of the selected text, I noticed that there was a problem when you tried highlighting the entire word, with some characters in the word having different fonts, and then formatting (bolding, underlining, etc.) the text. The error I get is[code]...
Notice how the "Ma" is in the Comic Sans MS font and that the "th" is in the Arial font. If I were to highlight this word on my program and try bolding it, the error would pop up.
