Save Array To Text File?

Sep 19, 2010

My homework task is to add data to an array of records and then save this to a file.

I'm having problem saving to a text file. I have the following code:

Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click
Dim SW As New StreamWriter("Records.dat", False)


In my test example here I realise that the reason I have 4 lines written is because I have 4 elements to the array, but why am I getting this gobbledegook instead of records with a name and age?

I know I have added the data correctly to the structure because I can redisplay it elsewhere on my form. I just don't get how to save data in a structure to a text file.

My task requires use of an array and/or array of records, a text file

Save A 2-dimensional Array As A Csv File?

Aug 30, 2009

I am using visual studio 8. have an array, array1(100,8) and I want to save it as a csv file so that I can open it in excel and examine the contents more closely. The feature, of saving as a csv file, is not going to form an integral part of the finished vb app, I just need something quick and dirty because the data in the array just requires looking at in excel so that I can fully understand its significance and thus continue coding my app.

Creating An Array From A CSV Text File And Selecting Certain Parts Of The Array?

Mar 20, 2011

I have a Comma Separated value file in .txt format... simply put, its a bunch of data delimited by commas and text qualifier is separated with ""For example:

"So and so","1234","Blah Blah", "Foo","Bar","","","",""

Where ever there is a carriage return it signifies a new row and every comma separates a new column from another.My next step is to go into and create an array using these values and having the commas serve as the delimeter and somehow making the array into a table where the text files' format matches the array After that array has been created, I need to select only certain parts of that array and store the value into a variable for later use.... how to make the array and selecting the certain info out of it..

Save Image File From Byte Array?

Feb 9, 2012

I have this code which saves an "Image" to a SQL Server database:

'You have the images in the PictureBoxes, now you need to store it as a Reference Image
'if the user has selected that option
Dim ms2 As New MemoryStream()


I am working on a PHP site at the moment that is having trouble reading that data to display the image, so I am attempting to not only save it to the DB, but also save it as a bitmap or other file type to the actual server.

How can I create an image file (not really picky on which file type) from the "arrImage()" data above?

VS 2008 - Simple Text -> Xml Program - Save The Contents Of The Bottom Text Window To An Xml File

Dec 23, 2009

I have this Quiz software that lets you create online multiple choice quizzes which are great for studying (I am in grad school and I'm trying to use everything I can to learn). So the Quiz software is great but it only lets you input questions by hand, one by one. I took a look at the .xml file that the quiz program spits out and came up with the idea to try and make a converter so that I can import many questions at once. I was hoping to try and solve this limitation by doing the following:

Take a .doc that say a tutor gives us with a bunch of practice questions, and then take that into Crimson Editor, and then format it so the question is on line 1, the multiple choice answers are on lines 3,4,5, and 6, (for the next question, the question would be on line 11, and the answers on lines 13, 14, 15, and 16, and so on) and then take that saved .txt file into my program, hit the generate button, and it will spit out the .xml file, and then import that into the quiz software to generate the online quiz.

Here is an attached screenshot of my program layout so far:

I figured out how to open a text file by watching simple youtube tutorials, but I don't know how to have it generate the stuff and have it show up in the bottom text box. I know how to do the coding to convert the txt to proper xml code but I don't know how to be able to save the contents of the bottom text window to an xml file.

File I/O And Registry :: Using The SaveFileDialog To Save Listbox Info Into A Text File?

Mar 17, 2010

I'm using the SaveFileDialog to save listbox info into a text file. The files save fine, but when you go to save the file, if you hit the cancel button, it will overwrite the previous file you saved, because it's name was the same and it seems to save the previous file as the new name for your next file. Is there any way to catch if the user clicks cancel, and then exiting the sub if they did?

Dynamic ToolTip For Dynamic Text Box?

Jan 11, 2012

OK, I'm trying to display tooltip text for a dynamic edit box. Well, at least I'm trying to.

On my form, I've got a tool tip control which I've conveniently named ToolTip. My edit box displays OK. But, what I want to do is when the user hovers their mouse over the text box, I want the tool tip to display some text.

I think there are two problems that I'm having. I'm not convinced that I'm properly addressing a dynamic text box name. Ideally, I would want to be able to refer to the text box (but using a dynamic variable that will contain the prefix of the name). To hardcode, I would want to be able to achieve (not in this example but in theory): ABCDEFGt_0300.Text = "hello"

Dim controllerName as string = "ABCDEFG"
Dim t_0300 As New TextBox()
