I'm having the following error message with a date value in production server. "The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value" In the development server the problem never happened. Both production and development servers have the same OS (Windows Server 2003), updates and settings including the regional settings options. The regional options is set to Arabic (Saudi Arabia) and the date is customized to use (English) gorgerin calendar. The non-Unicode is set to Arabic (Saudi Arabia).
My solution contains an ASP.NET web application and a class library. In my class library project I'm trying to get a list of rows from the database (SQL 2005) and I'm using a date rang [Code] Is there a way that I can use to manipulate dates regardless of the regional options settings?
I'm wanting to loop through a range of dates set by date time picker. This is my code and as the SD.Value.Date is 23/05/2010 it shows Sunday for me. However on the Loop it keeps showing Sunday and Never stops.

Dim ED As Date = EndSearchDate.Value.Date
Do While SD.Date <= ED.Date
MsgBox(SD.DayOfWeek.ToString)

how to convert string to datetime and calculate date
View 3 RepliesI'm trying to match a certain DateTime value with the current system DateTime. I have a timer and a label on a form. Timer interval is set to 1000. When the form loads, the timer starts ticking. As soon as the current DateTime matches the value of the variable, it shows a message in the label. When I'm writing the following code, the values don't match even if the current system DateTime is equal to the variable. Label1 isn't showing 'Times Matched':[code]The default format of 'Now' is the same as I have stored in dtmVar variable. So there's no question of format mismatch. Does that mean 'Now' is not actually a DateTime property? Provided, my O.S. is Windows Vista Ultimate and all date/time settings are set to default.

Makes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
See below.

Option Strict On

I try to compare Datetime.Now with a Datetime variable I set, using the Datetime.CompareTo() method. I use a timer to compare these every second and display the result, but as the current time approaches the time I set, the result changes from 1 to -1, but never 0, which means these two are never equal. I'm suspecting the Datetime structure contains milliseconds?

I'm using vb in excel 2007 and need to work through a range or array, the size of which varies from time to time.
The examples of using range always demonstrate using literals eg "A1:A25"
How can I programatically determine the end of the range - ie up to where the cells value is blank
And then can I use a variable in the range statement - eg .[A1:Lastcell]

So I made a simple patform game where the player has to jump quickly while the platforms move to the bottom of the screen, as to not touch the bottom of the screen. But, I need to know how to create a loop to loop the locations of the platform. This means that after twenty or so platforms, the same platforms come up again, so that the player will have an "endless" game. I've declared all the platform's locations relative to the location of the first repeating platform:

I'm building this class to download files in parts/sections/segments. In .NET 4.0, I can use this code to specify the range to download from
long startPos = int.MaxValue+1;
HttpWebRequest.AddRange(startPos);
and it works because there is a long overload for the AddRange method. When I looked up the .NET 3.5 version, I realised the AddRange() method allows using int only. The possible workaround would be using the AddRange(string, int) or AddRange(string, int, int) methods. Since the class will have to work in .NET 3.5, I'll have to go with the string specification but unfortunately I can't seem to find any sample code that shows how to specify ranges using this procedure in .NET 3.5. Can anyone show be how to do this?As the first code sample I wrote shows, I would like to specify a range of type long instead of int. Using type int allows requesting for byte ranges only up to 2GB but long allows requesting for byte ranges beyong 2GB.
The question therefore is: How do I specify byte ranges of 2GB or higher on HttpWebRequest in .NET 3.5?
