View 4 RepliesVS 2008 Cannot Read Integer As Primary Key To Save To Database
Nov 13, 2009I'm using Visual Studio 2008 and MS Access 2007.
I have linked the database to vs2008.
The first problem I have now is how to add all the data to the combobox from access 2007? [I have solved this myself accidentally.]
The second problem I have is I cannot save the primary key.
Assume that I have these:
Table name: tCustomer
Fields:
ID Datatype [Text]
[Code]....
Now, the user fills in the form. The ID cannot be edited by them where it's automatically counts the number of customer in database and give the id. For example, I already have 3 customers in the database so when I add new Customer, it will be 4 for the ID.
When I click save, it shows me the message of "Index or primary key cannot contain a Null value." I have set an input mask for my Customer. So, can I make it to save in a format like CT001, CT002, CT003 automatically?

VS 2008 Save Variable Vales After Close
Jun 3, 2011This is the first time that I will have ever actually published a program and I have a question about when it goes into 'real use' Right now I have string variables that sets the values of a few text boxes that can be edited and 'saved' (the variable values change to the new input).
When I publish the program will these values be saved in the variables after the program is closed then re-opened? Or is everything reset when the program is restarted? And if it is all reset, is there anything internal (aka not a xml file or something) that will hold the data and keep the changes?

View 2 RepliesVS 2005 - Length Of Array Is Integer Variable
Apr 26, 2009I have a problem when debugging a code. On top of class I declare an array, and the length of array is an integer variable which is applied value below declaration of array.
E.g. class declaration
Dim array1 (2, integer) as string
Public Sub
integer = 5
End Sub
So basically, array is created with integer being 0 or whatever, because it is declared before integer was assigned a value. But the problem is, I need it to be declared at class variable so I can use array in different subs.
VS 2010 Anyway To Customize A Variable To Use Both Integer And Boolean Value?
Aug 19, 2011Is there anyway to customize a variable to use both an integer and a boolean value?For example. I am kind of making a simulation engine and using GDI as a visual aid, I am generating a grid of tiles for objects to be displayed, but I do NOT want to repaint all the tiles just the ones that have changed, so that I can save fps.So I thought if I could set a variable for the "tile number", "how many objects there are on a tile", and a boolean value for whether or not the tile needs repainted.[code]

Convert String To Integer With Variable Decimal Sign?
Nov 22, 2011I am currently looking into the conversion of a string value to an integer. Obviously I will need to do some validation as to whether the passed value is in fact convertible to an integer.
At the heart of my question is this: the users' local is nl-BE (dutch (Belgium)), which means that we use a comma as decimal sign (and points as thousands separator); e.g. 123.456,78 would be a valid nl-BE number. Now, when using the numeric keypad, the
decimal key will yield a point, not a comma (weird huh!). So many user will enter 123456.12 and when converted to an Int, this should yield 123456.
The thing is that I want to cover all possible angles; both points and commas may be used as decimal sign by the users. So I wondering if anyone has written some code that deals with such a situation. I was thinking of an extension method that makes the
conversion based on whether a point or a comma is last used in the passed string (since no thousands separators should occur after the decimal sign).

VS 2010 - Creating A Program - To Secretly Save When The User Clicks On Save
Feb 7, 2011I'm creating a program and i want it to secretly save when the user clicks on save.
In other words, i have made it so that it saves twice. Once for the user to read (like a fancy copy) and another that the program uses to open up the form.
Currently when pushed, 2 save dialog boxes come up after each other. I don't want this to happen. I want 1 to come up (the user friendly, fancy version) which is the easy part, but i also want the other 1 to save automatically and secretly without asking the user to set the destination.
