When I try to close my form it gives me the following error; Error converting data type varchar to numeric. I have only one field which is numeric - ProjectID, and when I close this form sometimes this txtProjectID is empty and this calls the error. But if there is a number in the txtProjectID it closes fine.

I'm pulling records from a db table (sybase) where I have run into a problem with a long varchar field. Using the OLEdb class I convert the field into a string variable which works fine in most cases, but there are problem with a few records. Examining the field in the database it shows that the value is not null, but the length of the field is 0.(SELECT field, length(field) FROM table). When I try to convert this into a string the result is rubbish.strContent = objReader.Item(i). I can't figure out what's the problem here, so I have avoided the issue by doing a table update before I start the process of getting data (I set the field value to null if field.length = 0

View 1 RepliesI don't know how to convert the nvarchar value into an int, but that is the way it needs to be set up. I've found other posts about this but I don't know how to use CAST in the INSERT statement I have. All the posts I could find were about converting to int in SELECT statements. I need this statement to change the field @Duration to an int in the database. @Duration is an amount of time. (01:00, 02:00...) They will all get rounded up to the next int value. So if a user enters 0:45, it should be converted to 1. how to get this INSERT to work?

I'm having an issue with my base conversion program. It seems to have a problem converting from base36 to base10 properly. After debugging all night, I've found that it's one certain function that's not working properly. The function seems to convert every last test number correctly, until I start getting into 11-digit numbers in base36. I have the max digits allowable for base36 set to 12 (so as not to exceed the base10 18-quintillion or so that an unsigned long can hold). I'm starting to think the issue is with VB and not with my code.The function as I've written it is below (DIGITS is a global const string ="0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ", and itr is a global integer used throughout the code for iteration):
'-----------------
Public Function FromBase10(ByVal iValue As ULong, ByVal cBase As ULong) As String
Dim remaining As ULong = iValue

I haven't got the code, however I got the physical part of the program done with a label called Numeric Number and another called Roman Numeral, with text boxs next to each label. I also have a button called "convert" so when you enter a numeric number in, it'll convert it to a roman numeral. I need it to only convert from 1 to 10, but not accept a number less than 1 or more than 10.
Description of Program/Events. I would like to come up with a number generator that takes the Total number (for this example I'll say 20), divides it by 2, and does alternating additions so the end result will generate a list like this:
1, 11, 2, 12, 3, 13, 4, 14, 5, 15, 6, 16, 7, 17, 8, 18, 9, 19, 10, 20.
I can understand the arithmetic, just can't work out how to express this in code. The end result would be save in a .Txt file (I have added a SaveFileDialog1 control, but figure I need to get the result before I work on the export).
Dim StartValue As Integer
Dim EndValue As Integer
Dim TotalValue As Integer

Im having an issue with a Stored Procedure I have written,I can call it in management studio and it works fine, yet calling it from my codebehind gives this error The conversion of a varchar data type to a datetime data type resulted in an out-of-range value. when i call da.Fill(dt)What is really puzzling me here is that I dont actually convert anything from varchar to datetime, the most I do with the date variables is format them into a different datetime format.

I cant see where this error could be coming from, having tested running it in SQL management studio without error I am pretty sure the error is in the VB.My first thought was that maybe the parameter I am passing in the @start / @end values arent being recognised as DateTime so I tried adding the parameters like:
Dim p As New SqlParameter
p.SqlDbType = SqlDbType.DateTime
p.ParameterName = "@start"[code]....
