When I Hit The "Save" Button, It Crashes And Says That The Column "Serial Number" Has Exceeded The MaxLength?
Oct 10, 2011
I've made a program that basically keeps track of all your CD Serial Keys. I've made the database and I'm at the point where I can type it all in and hit a "Add New" button to add it to the database, but when I hit the "Save" button, it crashes and says that the column "Serial Number" has exceeded the MaxLength....I don't get it...the numbers you put in the "serial number" is something like this "X5J3-2K4L5-2P4OK-23VMN-903NC" that's 24 numbers and letters long...I have changed the MaxLength property for the column to 30,000. How is 24 numbers and letters exceeded the MaxLength of 30,000? I think my "Serial Number" is setup for text. How do I fix this?

I got this error message when I only typed about 60characters. I have no idea why this happened to me since I have my address datatype set to varchar(100), I even had it set to varchar(MAX) at one stage but that made no difference. May I know what I've done?

I have several controls on aWinForm (VS2010) which are bound to an SQL database table via a Dataset, BindingSource and TableAdapter (all bindings created via the IDE). When i try to update the daatbase table with changes made in the form controls using:
Me.QuoteHeaderBindingSource.EndEdit()Me.QuoteHeaderTableAdapter.Update(Me.BurdensCRMDataSet.QuoteHeader)
I'm getting the following error message: Cannot set column 'SalesTeam'. The value violates the MaxLength limit of this column Now on the surface the problem would seem self explanatory and the solution quite obvious. However i'm not changing the 'salesTeam' data, so it's exactly the same as it came out of the database and consequently it must be the same length. the data is two characters, the database field is a Char(2) data type and the datatable field has MaxLength = 2. So i can't see what's causing the problem or what i can do to resolve it
I've tried changing the data in the relevant textbox to just one character, but it still throws up the same error I've tried changing the SalesTeam DataTable field to MaxLength = 4, but it still throws up the same error I've tried reconfiguring the TableAdapter, but it still throws up the same error
I know my code is good because it works for other datatables that other controls in the same form are bound to. I'm I doing something wrong or missing something obvious or has anyone come up against this before

OS: windows 7 64-bit /Programming Language: Visual Basic.net on Visual Studio 2010 express edition.I have dataset with 4 tables each one of them is a datasource to a datagridview I want to add a serial number column to the datagridview so I made this
DataGridView1.Columns.Add("serial", "SER.")
For x As Integer = 0 To (ds.Tables("workers").Rows.Count - 1)
DataGridView1("serial", x).Value = (x + 1)
Next
It was working fine untill I added a relationship to the dataset the relationships codes were
Dim relation_WC As New DataRelation("relation_WC", ds.Tables("workers").Columns("id"), ds.Tables("cources_jun").Columns("workerid"))
Dim relation_WV As New DataRelation("relation_WV", ds.Tables("workers").Columns("id"), ds.Tables("vacations_jun").Columns("workerid"))
[code]....
I breaked point the debuging and I found that the serial number column I added is fine and has it's values, but when I reach the line relations.add(the_relation) the serial number column loses it's values and turn into an empty column with no
numbers in it....why this is happening?
Note: I added another relations but the only relations that clear the serial number column are the relations that has a datatable that is a datasource to the datagridview that has the serial number column.

I'm using VS 2005, after VB6 to VB.NET conversion we have fixed all the errors but still have unidentified number of warnings. Is there any way to increase this limit of 101 warning you can see after compiling? I want to actually see the total number of warnings to get an idea how much work is there.

I wrote a function to format numbers like this: 123456100,12 -> 123.456.100,12 (I have a function too, which converts numbers from this strings).Now, I have a dgv and a column with these numbers (or rather strings). The sort mode is set to automatic. If I sort the column, it doesn't work, because the values are not really numbers, but strings. But I get the same result (the sorting doesn't work), if I use the formatnumber function (this returns strings too).
I could use the programmatic sort mode and before sorting I format the strings to numbers, then sort the column, and then format the numbers like above. But this is a bit slow (the dgv has appr. 800 rows), and in this case, I haven't an arrow next to the column header text.is it possible to sort the column like a normal number-column with automatic sortmode?

I am making my first application which involves WMI.. Using the documentation provided by MSDN and the Forums I have managed to get data related to the Win32 Class (Computer Name, Physical Memory, IP Address, etc..) Now I would like to get the Serial number of the monitor. I believe I have to use the WmiMonitorID Class. However, I do not know the Syntax to access the property of the same. I had used the code below for the win32 class. How do I modify it for the WmiMonitorID Class?
Public Function OpSys() As String()
Dim Str(4) As String

i am making a program in visual basic 2008 and when the program first starts up on acomputer/device i want it to come up with a screen that asks for a serial key. i also only want the serial key (that i give to the person i am giving the program to) to be accepted once.eg. if he copies the program and gives it to another person who takes it home, they have to enter a new one (that i would have to give them). if they enter the same key as person 1, i want to deny access.
