Loading And Saving A Multi-dimensional Array?
Oct 18, 2009What would be the best way to load and save a multi-dimensional array (of bytes). I've looked through streamreader tutorials but it always seems to instructions on how to save strings. I also know there's a very easy way to save a one-dimensional array, but it doesn't work on multi-dimensional ones. What should I be reading up on?
View 5 RepliesSaving/Loading The Entire File?
Jul 31, 2009Using the Microsoft VB 2008 Express program, I'm making a SWd20 character sheet (D&D) to be distributed to a few friends. It's a program where the user can figure out stats, species, class, etc without having to make any calculations him/herself.. but this will all be in vain without saving it..
So I'd love to know how I could make it so the user can save and load the entire file(including buttons, labels, text boxes, menu strips, possibly multiple forms, etc) on his/her own computer.. Is this possible, and if so, how can I go about this?
I've already searched through and found lots on saving text in the files to .txt files, but that doesn't cover everything I need

VS 2008 Saving And Loading Variables To And From A Text File?
Mar 22, 2009visual basic 2008
I am pretty good with visual basic and visual studio, but the one problem I have is saving... I am currently creating a game, and it has a lot of variables, I want o be able to save all those variables to a text file and then re-open it later. When it is open, i want the variables to have the original value from the text document.
To sum it up: I need variables to be saved in a text file, and then be able to open the text file back and have the variables have the proper values from the text file.
I have been searching around google, and I found ideas, but I have no idea how to use them. Like using XML or saving a table with " TextFile.WriteFromTable" "TextFile.ReadToTable" but I don't exactly get how to use those (the posts weren't too clear)

VS 2008 Loading File Into Array?
Jan 22, 2011I have a Customer File, and want to serach through the customer file to find a customer. I want to be able to Load the data into an array, and then from that array into the list view. BUT i don't want all of the feilds. I only want 3 (out of a total of 7), CUST ID, FNAME, Lname, etc. When the user clicks on the searched Customer, it then displays that customer in the form.
What I am not sure about doing is loading the file into an array
Edit: The file is a .dat file. I will happily attached my form if someone requires it
EDIT2: Can't count to 7
Saving Lines From File To Array?
May 2, 2011I'm working on a program that when you click a button called new it pops up a new form asking for you to enter a directory location. If the directory exists it saves it into this file:
"C:WindowsSettingsButtonVariableSaves.ini"
I already have working code that saves each directory entered into the ini file on its own line.
Now in this code I'm trying to call each variable back from the ini file when form1_loads and set it to an array called ary() so later I can set the first 10 saved within the array.
So later:
button1.text = ary(1)
button2.text = ary(2)
and so on to
button10.text = ary(10)
and the reason I set the array to record all lines even if theres more than 10 because I want to be able to add more buttons later on.
Here's my current code for saving lines to an array:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim FILE_NAME As String = "C:WindowsSettingsButtonVariableSaves.ini"

Jul 16, 2010i need to save an array of intptrs as a part of a structure in a file, vb.net gives me "File I/O of a structure with field 'pList' of type 'IntPtr' is not valid." error, ok i figured and tried to convert them to integers and while it worked for other singular intptrs it did not for the array as it just throws me a conversion error. I then tried rebuilding the array in the new sub of the save structure and while that sorta worked(i think) it then gives a "bad size" error when saving. Im out of ideas, saving the array elements one by one would be suicide as the amount varies and is well in hundreds,

I haven't worked with databases, so my knowledge is limited.

VS 2005 3d Arrays- Saving And Loading?
Apr 2, 2012I am doing a project for part of my coursework which involves the creation of a series circuit designer.
I am having some trouble with the saving and loading functions; I had intended to save them to a text file with commas separating the component name and the value (if any) attributed with it.
Grid(xcoord, ycoord, 0) contains the component name. Grid(xcoord, ycoord, 1) contains the attached value (resistance or voltage- components such as wires have a value here of 0)
Once the save button is pressed, the text file contains 50 rows of "0".
P.S. Let me know if any other parts of my program are required.

Const maxsize = 50

VS 2010 Loading And Saving To .txt From Datagridview?
May 9, 2012what I am trying to do is get a program to load data from a text file with multiple lines in the form "Name, Type, Stocklvl, Price, Location, Reorderlvl" then display it all in a data grid. From where it can be viewed and edited as well as saved back into the original file stock.txt as well as generating a separate file reorder.txt which includes data on what needs to be reordered and the date which updates on program exit. I have chosen to use datagridview something I'm unfamiliar with as I figure It'd probably be the most functional to meet my needs of displaying a lot of data clearly as much as 200 items.
