I would like to know that how am i going to validate the data inside a currency field to see whether its format is correct or not ?How am i going to reload the data when an action is canceled ?

I have this code that will import the excel sheet to the datatable then inserts it in the database, but I have this problem.I have set the HDR to yes so that the first row will be considered as its header, but the problem now is that if the first row is null, the datatable will automatically named it's header as f1,f2 and so on. how can I set the header as null if the first row is null? so I can validate it afterwards

I have a combo box that contains data from a database.I am using autocomplete to assist users in finding the large amount of data that the combo box is bound to.What I need to do is check the typed data with the values bound to the box.I need to show a message box if what the user types isn't in the list. Right now if its not in the list and they tab out of the box it throws an exception.Is there a way to validate what is typed with the data in the list. I tried changing the drop down style to dropdownlist but this doesn't allow the user to type in data.
In a Windows XP Pro environment, my system uses a mainframe emulator in a window in which a scanning application is running. The data populating the mainframe app comes from various instruments, scales, barcode scanners, etc.. The data inputs are captured by a winwedge type RS232 data aquisition software.
When all the data is processed correctly, the mainframe application sends an "operation completed" message and creates an exclamation system event associated with a specific sound to inform the user.
My goal is to create a MS Access application that would use the Exclamation system event to validate writing the barcode that was just read to a database without further querying the mainframe, creating a local database. I only want to write the barcode when the mainframe application completed and therefore played the sound.
I am working on a VB.NET windows applications. It reads data from a text file and inserts them into SQL server DB using SQL Bulk copy.I want to validate the length of all the fields in the file. The maximum length allowed for evey field is stored in tbFieldLength table. File has 50 columns and 10,000 rows and the values are separated by '|' symbol.
If the length of a value in any row is greater than the length specified in the tbFieldLength table, I want throw an error with exact row and column details. For example,saying
"Lenght of the value in Row 6, Column 20 is greater than the expected length"Also, I want to identify all the places if the error occurs in multiple locations. What is the best way to validate the length of fields in the text file?
I have an application has a data entry form, and currently I'm using the form validation and validated events to validate the data - along with an error provider. I've read that this logic should be placed in the Dataset rather than the form. To that end, i've started exploring how to do that.
Dense student here with little sleep here during finals week...I have a text field being read on a button click event (along with lots of other information being read). This field needs to have a number entered.
I either:
1) Force a default value (i.e. - "2")
2) Verify there's something in the field AND that something is numeric...
So right now it all looks pretty with ... <button type="submit" runat="server" name="subscribe" id="Button1" class="link-button" onserverclick="saveListing"> Until it is time to validate the data before calling saveListing function codebehind (in VB .Net). How can true/false be return so that when true saveListing will be called, otherwise not?
I'd like to write a license management based on a wcf services.
How can I ensure that the (end)-user/"hacker" can not replace our license management services with a corrupt server?
Our license server is hosted on our server in the internet. When the server send corrupt data to the client the complete license management concept is destroyed.

I have written a small XML validator, that takes in an XML file and an XML schema and validates the XML files against that schema. It works well, except for an XML file, with this content:
I have modified the MSDN example to reflect my problem. When using a namespace I can't get the document to validate as I would expect and when validating a document that doesnt have a namespace it validates regardless of whether or not it has an error in it or not.
Dim errors As Boolean = False
Private Sub XSDErrors(ByVal o As Object, ByVal e As ValidationEventArgs) Console.WriteLine("{0}", e.Message) errors = True End Sub
I'm working on a program to delete files from a certain folder after they have aged a certain amount of time and either match via regex or extension. I'm running into an issue where files() could be: files(0) = Nothing files(1) = Nothing files(2) = Nothing etc....
Right now the way it is written, I could place Else log(1) = data(1) log(3) = "Array field empty" InsertLog(log)
And the program would log as many files as file(i) = Nothing holds. This would create redundant database records and is not wanted. Is there a way to figure out if ALL files(i) = Nothing and then place code in there to insert into the database?
'If log(3) is successful that means no files were old enough or deleted successfully If log(3) = "Success" And IsArray(files) Then For Each file In files If Not file.IsNullOrEmpty(file) Then 'If files is actually something insert into the log log(1) = file [Code] .....
I have a form with a textbox, and i would like validation to occur so that a blank field is not allowed e.Cancel = String.IsNullOrEmpty(TextBox.Text) Does not always work, because it still allows me overwrite an existing field with blank spaces, and then update.
