Saving Data To A Random File Using A Fixed Array Element Error
Feb 7, 2012The file structure is fine for retrieving data from the file but when I go to write data to the elements and hit any of the fixed array elements, I get an exception error. this has got to be a sytax problem I am just not seeing.
It seems that I am not addressing the array member correctly yet the same logic pulls it properly from existing records on file.
in a Module I have the structure as follows:

Sep 19, 2010I need to control a device with a GPIB port. I have the commands that I need to use to do this; but I don't know which is the sintaxis in Visual Basic.

The main tasks that I need to program are sending data, receiving data, and saving data
Saving The Value In A Textbox To An Array?
Feb 9, 2010I have a form that display's 5 text boxes for student names. Each student names has 5 text boxes to the right of it, the text boxes to the right are for 5 test scores to be inputted.

View 6 RepliesSaving 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"

View 2 RepliesSaving Replicated Data - Current Data Saved To Appear In Page Within All The Relevant Fields?
Jun 2, 2010What I am trying tot achieve is the following:User inputs data in one form that saves to the dataset table no problems. On an edit screen I want the current data saved to appear in this page within all the relevant fields but when saving I want this data to add to the dataset table as an additional line of data so the transaction records are kept.I want to add a new datarow regardless of it saving one change or all 7 changes that are possble.
e.g. Line 1 - user inputs 7 cells of data Line 2 - user amends 2 cells of data Line 3 - user amends 1 cell of data an so on. Unfortunately the terminology for certain items above may not be correct as I am still new to this programming and still on a massive learning curve.At the moment I do not have the code for what I am trying to achieve as I really dont know where to start with it.I am currently able to save the data and have it appear in the "edit" panel however only the cells changed are saved an it overwirtes the initial input.

View 6 RepliesArray Of Objects Also Saving Variables Of Class?
Dec 21, 2011I have a small class of Object CellValue
Friend Class CellValue
Public CellColor As Color = Color.White
Public CellShape As Shape = Shape.Blank
Public CellName As String = ""
End Class
Then in my main I make an array of CellValue but I want to know if the values are also being passed down with the array.
Dim Plan(SizeW - 1, SizeH - 1) As CellValue
Dim CellW As Integer = PictureBox1.Width \ SizeW
Dim CellH As Integer = PictureBox1.Height \ SizeH
[Code].....
Are CellName, CellShape and CellColor being tied to each element in the array?. The reason is because I need to use these properties to tie certain functions to them. The CellName should have a MachineID which I would have to use to pull some info from a Database.
The Array should also be serialized and deserialized to XML as customer needs to create/edit and delete certain values in the array. And in order to save the array has to be in XML
So the Questions are does it save the CellName, CellShape and CellColor for each element, will it be affected if I serialize and deserialize using XML. If possible, how can I call up the Cellname p.e for a specific array element.

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,

View 1 Replies60K Data Saving To Database
Nov 6, 2011I'm working on a project which are generating some data from my VB.NET software and I wish to save those data into sql server. But my concerns is the speed of saving and the large amount of data. For every 0.5s, one set of data will be generated and the process will keep running for about 8 hours, so at the end of 8 hours, roughly there will be 60,000 set of data generated.May i know what is the best option/method of saving the data into the sql server in not hanging up my software and also keeping the pace with the speed of 0.5s data being generated?
- Speed of 0.5s. I have to maintained for every 0.5s, one data must be generated. Cannot delay too much.
- I can afford delay in the sql database, meant the data might not be necessary close to real time.
Data In Application Not Saving
Aug 19, 2011I have a small application that consist of five tables. The main table is called inventory. I have four tables linked to the Inventory table
[code...]
I can go in and enter data, create a new record and add more data and then click Save - nothing happens. I can cycle through the records and they will show. However when I exit and reenter the program (stop/start debugging) done of my new data is displayed.
I am thinking the problem has to be with the four tables connected to the main table via the ID's. Although a record is not being added to these subtables. So, I am not sure what's going on.
I have provided the code below. Please take a look and give me some direction.

Form Data And Saving
Oct 11, 2009I have created a form, that calculates Hotels billing, with one box I can input Number of nights a customer stayed which is £32.50 a night per room and the other box £4.50 for breakfast, there is a deposit of £25.00 which gets deducted upon departure. I have created this form with success along with a clear button But here is the tricky part- I want to create a total button which will display a summary information about the bills paid on that day regardless of how long they have stayed and how many breakfasts consumed. this should include, the total number of bills paid, the total number of nights paid for, the number of breakfasts paid for, the total amount of all the bills added together including the deposit.
