Using MySQL 5.
In my SAP.NEt project, defined a constant:
public static DateTime NullDateTime = DateTime.MinValue;
I have a function:
protected static DateTime GetDateTime(DataRow row, string columnName)
{
return (row[columnName] != DBNull.Value) ?
Convert.ToDateTime(row[columnName]) :
Globals.NullDateTime;
}
In the source code:
public DateTime StationFeedTime{ get; set; }
StationFeedTime = GetDateTime(row, "StationFeedTime");
I ran a SQL to fetch records from MySQL, this field is Time field in MySQL.
Got an exception inside the function:
Unable to cast object of type 'System.TimeSpan' to type 'System.IConvertible'.
I am trying to find out the best method or practice to use a dropdownlist to feed my oracleparameter value. I currently have this working when I have a value selected in the dropdownlist. My issue is how to account for if the user leaves the dropdownlist empty. I want this to then return all data. My SQL has a where clause = to :HRM. I use a function that gets the text for my SQL from a text file. My dropdownlist box is populated via databind. I then inserted a item in my dropdown with 0 index with no text display and a value of "novalue" Below is my code to populate my dropdownlist
[Code]....
[Code]....
If I select an item and run my code it works great. This doesnt work with the no selection tho. Do I have to build the SQL dynamically with a check if the listbox is empty or not and then add the criteria? I was hoping there was a eailer way since I have many queries and parameters to build.
Here is part of my code using the oracleparameter.
[Code]....
I also saw a post about trying this, but I get an illegal error.
[Code]....
Not sure if I can replace the "AND HRM_FIELD = " text and use :HRM instead and then build the oracleparameter with an IIF to include the AND HRM_FIELD part.

Is there a way to get the difference between two dates in Month. I would like decimal for the day.
EX :
First Date : 2010-12-20
Second Date : 2011-12-30
This is like 1 months and 10 days between these date.
The difference should give me : 1.33
DateTime dt = new DateTime();
dt = Convert.ToDateTime("2011-12-30"); ;
DateTime dt2 = new DateTime();
dt2 = Convert.ToDateTime("2010-12-20");
int monthDiff = System.Data.Linq.SqlClient.SqlMethods.DateDiffMonth(dt,dt2);

when updating a decimal field in a GridView all is fine when using e.g. "2.3" ("." to separate the fraction!)
However, when using "2,3" I get e formatstring exception!
I tried "regularExpressionValidator/RequiredFieldvalidator" but did not succeed! Tried also with FormatString like {0:n}.....
Questions:
is this controllable by "Culture / UICulture" in web.config (played with it without success!
How do I best check for correct input i.e. force "." as separator
Can I use the "DataFormatString" property for the appropriate GridView field (like {0:n}) ......

I was read your post: "Export GridView to Excel in ASP.Net with Formatting using C#" and is very useful. That code works perfect. But I need create a new format for a specific column in my sheet before to export it. For example:My DataTable have a column with decimal numbers and I'm trying reduce the tenths for each number.I want this: 2,874444 ----> 2,87 for a specific range. In this case I need it for all numbers in the column 13 or well said for the Column called N in Excel. Only reduce two tenths.
I used:
xlWorkSheet.Range["N"+h,"N"+h].NumberFormat = "0.00";
And no works (h is for rows, N is the column. Into a foreach).

The answer of which should add on 0.5 to the original value. If I were to use the increase value of 60 which then becomes 60/60 it will work.I'm dividing by 60 because the increase value is per hour so I make it smaller to get per minute value. Why is it doing this?
Some values are returning 2.0 but I need it to be 2.00 as this is a money value that is displayed to the web page.
I am doing:
Math.Round(value, 2);
Is there a way to force it to 2 numbers after the decimal?
