switching our database over to UTF-8 (multi-byte char, unicode) encoding from IBM819 (single-byte char, Latin1 subset), because of a new requirement to support text entry of Czech characters.I've just been reminded by a colleague of the nchar and nvarchar column types, which neither of us has actually ever used.
If I were to define the relevant columns as nchar and nvarchar instead of char and varchar, what would I have to do to allow my currently-IBM819 database to work with this new IBM819-incompatible text coming in from my .net application?Would all conversion be automatic? Would I need to write some scary conversion code?
EDIT: Right, I defined an "nchartest" table containing a single column, "ntest" of type nchar(500).I connected to that via .net code and confirmed that 500 chars of lorem ipsum could be entered:
Dim insertString As String = "INSERT INTO nchartest VALUES (?)"
Dim insertCommand As New IfxCommand(insertString, cConnection, tTransaction)
insertCommand.Parameters.Add("incident_recno", IfxType.NChar).Value = "[lipsum]"
Return insertCommand.ExecuteNonQuery
I then replaced the lipsum string with 100 or so chars of Czech text, and attempting to insert that caused an IfxException to be thrown by the .net Informix interface, with the message ERROR [HY000] [Informix .NET provider]Unspecified System Error = -21005.
Following up on some research I did yesterday, I tried setting my CLIENT_LOCALE setting in my connection string to en_US to match that reported by Threading.Thread.CurrentThread.CurrentUICulture, but that connection could not be opened due to ERROR [HY000] [Informix .NET provider][Informix]Unable to load locale categories.
Following that, I tried setting CLIENT_LOCALE=en_US.unicode, which produced an ERROR [HY000] [Informix .NET provider][Informix]Unspecified System Error = -31142.

View 6 RepliesI have a table called PatrimoniuMasini.
What I need to do is simply copy all the values contained by column NumarMasina into Combobox1 of my Form. (i marked with red the values I need to copied into my combobox(combobox1 of my form) in fact there are 10 values I missed the last one. You can run the ddl provided below in sql server to see the output from my printscreen.
When I run the form in my combobox there are imported the values from NumarMasina column. (so this must be done in form_load callback it's sure).

I am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.

I am wriing a vb.net windows application to log and store information. then display it in a sortable multiple column listbox (I personally like FlexGrid by Component One). However... I am not sure how to go about storing the information. Should I go with a .sdf file database, registry, simply storing them in a file, or some other method?
What I need is to be able to:
read/write/delete from it
read possibly up to a 20mb file and sorting it without a lot of lag
be transported to multiple systems and maintain these writes (installed on many systems)
I know I could split up the reading/writing to anther thread. Even to other .DLL's and whatnot. But as for storing. Not sure what the best option is.

For my website I've just implemented tinyMCE for my site (just a word processor). Everything works fine except when i try to store the string variable input into a sql server database. I want to store a string and not have the html tags make me exceed the 8000 length limit(the html tags take up most of that space). My question is, is there a solution so I can store my document with the html tags without shortening my document? Create an if statement that will determine the length If > 8000 than split the string apart and insert into separate fields. Maybe their is a compression feature which I'm unaware of?

I need to be able to accept a password from a user in a WPF app, encrypt it then store this in a database and be able to decrypt later on. However I'm not sure how to implement this.
This is completely trivial so whether it's safe or not doesn't matter. All I need is for it to get working only I'm unsure exactly how to do it. I've tried playing around with the DESCryptoServiceProvider() but haven't gotten anywhere.
To be clear, how exactly do I go about converting a simple password into something that's been encrypted and storing it in the database (and what fields would I store it in). At this point, I'm happy if there's only one key and that key is being defined in the source code.
