I have a gridview that has a field called TargetDate which is formatted as dd/mm/yyyy. I want to substring the numbers out of the date. So basically remove the '/'. How do I do that? can't just substring(0,2) because sometimes the date is single digits, sometimes 2 digits. I am using vb.net.
View 2 RepliesI want to change one of my table columns data type. Now the column data type is varchar and i want to change it to float. Updated all the column data to numeric and tried to convert the datatype with the following syntax
alter table vibration_values alter column dis_v float
but getting the error as
Error converting data type varchar to float.
The statement has been terminated.
Suprisingly every thing worked well in sqlserver 2005 and not working in sqlserver 2000.
I have a SQL Server table with a number of fields that are defined with the "Float" data type. I'm running a simple query to retrieve the data from this table and use it to populate a Data Table in my C#.net application.
I just discovered that the data type of the Data Table fields is Double, not Float as I expected. As such, when I store a value like 0.157 it ends up getting stored like this: 0.15700000524520874
I'm aware that such extra "noise" occurs when such a conversion occurs. My major question has to do with why .Net didn't set the Data Type to Float (ie. Single) when the table was first populated?

I've checked that the values really are identical in the debug. I was under the impression that no conversion is neccessary between string and varchar, but maybe I'm wrong.
My filter Expression was working fine with filtering by Control Parameters.When I added the Phone Parameter it went nuts - with the Phone Parameter the GridView just Comes out blank upon loading the page (without it would show Select * from Individuals)Is it because the phone field is populated with numbers?

I have heard that even though the maximum varchar size is 8000, that we should not go higher than 7500 for the size value. What is the logic behind this advice?
View 1 RepliesI am trying to convert a field from a string to an int, then pass it to a query using tableadapters. I have the following function:
protected String countResponses(String value)
{
String input = value.ToString();
int fordb = Int32.Parse(input);
FrontendTableAdapters.ForumTableAdapter ta = new FrontendTableAdapters.ForumTableAdapter();
DataTable table = ta.CountPosts(value);
if (table.Rows.Count > 0)
{
return table.Rows[0].ItemArray[1].ToString();
}
else
{
return "Unknown";
}
}
It is working greate up to putting it in CountPosts() where I get the following error: Error 4Cannot implicitly convert type 'object' to 'System.Data.DataTable'. An explicit conversion exists (are you missing a cast?) :UsersDaveDesktopWebAppsFigmentvilleFigmentvilleyoursayDefault.aspx.cs 49 31 I think this is because it is looking for an int. But haven't I already converted it to an int?

What's the regular expression to check if a string starts with "mailto" or "ftp" or "joe" or...
Now I am using C# and code like this in a big if with many ors:

It looks like a regex would be better for this. Or is there a C# way I am missing here?

i have a strange error creaping into my web app but am unsure as to how to fix it. When i run this code on my debug workstation it works fine but when i transfer it to my server things seam to go wrong.
dev station (windows 7) + VS2010
regional and language settings all set to uk
server (windows 2008r2)
regional and language settings all set to uk
What seams to be happening is that when converting a string to a double it works correctly on the dev environment but moves the decimal place to the end on the server.
example code(vb)
dim lat as string = "52.983829"
dim long as string = "-0.036500"
dim latint as double = lat
dim longint as double = long
now on the dev server the value of latint is 52.983829 as you might expect but on when published to the server it becomes 52983829.0 the same with longint on the dev staion it is -0.036500 but on the server it becomes -36500.0 i get equally confusing problems if i try to change it to an integer instead.

I'm working against a database that wasn't designed by me and in all the tables there is a CreatedBy field that is an int. Now when I generate against this db i get all kinds of errors because subsonic is expecting that field to be a varchar.
I don't particularly want to go and rename the field in all of these tables so I was hoping there was a way to "alter" or change the internal convention (without getting into the source) in subsonic.
Has anyone been able/done this in subsonic 3.0.4??
