I have an app with clocks on it from around the world. It's used in multiple locations around the world as well, some that observe DST, some that do not.
Is there some way to get the current offset for various timezones from the OS? My preference would be to simply use the OS to GET the offsets, thereby relieving the program of having to figure out the dates and when to reset the clock. That would eliminate the need to be concerned with DST altogether; the offset values could simply be added to the current datetime.utcnow. I'd need to get the offset/current time for Hawaii, Pacific, Mountain, Central, Eastern, UK, France, Germany, Mumbai, China and Australia time zones.
TimeZoneInfo.GetSystemTimeZones can get at some of this data; is there maybe a way to cull it out of that?
I am creating a web chat application using asp.net vb. I have got the chat system to work as messages are sent and relayed back to the clients. But there was something i noticed but never thought it would be a problem. I am from England and the chat application is sitting on servers in America and noticed when the message displayed the time, the times were situated in American time zones. How would i go about setting the timezones that will correspond to there country timezones.So if the message display 17:00 American time, then the message sent to England should display 12:00 English time.
View 1 RepliesI have made a project where distance between two cities can be measured. But when I run the program its picking up wrong value from the database. [code] Textbox 1,2 (pickup) textbox 3,4 (desto) shows latitude and longitudes when item is selected from combo 4 and 2.the combo boxes are behaving as parent and child. For pickup section combo boxes I have binded them to d3dataset and did the relation with each other in the properties section. For desto section combo1 and 2 are binded to d3dataset1 and also related to each other. [code]

View 8 RepliesI built the sample project "How Do I" Data Access and ran into a problem adding, updating or deleting records. The project works like a champ until this step... It will let me delete, change or add records just fine, but when I save and close project and go back to my "show table data" in the database explorer nothing has changed?

See the code below which is triggered on a datagridview row validation event where the datagridview datasource is a datatable.
The messagebox shows that it loops around as expected populating the datarow with the expected values (NOTE: There are no primary keys as this is a college assignment with specific requirement and all fields can be nullable).
I had to use ImportRows as AddRows would always error due to "This row belongs to another table" the odd thing was the values were different and again the table contains no primary keys.
The code below runs but never adds a datarow to the dataset datatable "Bookings", does anyone know what the problem might be?

View 4 RepliesI have some combo boxes on a form and I want to add some elements into them . Practically I have to add "1" , "2" ..... "100" .
I can use this code :
ComboBoxMY.Items.Add("1")

...
ComboBoxMY.Items.Add("100")
but this will take too many lines . Of course I can accept that , but I just wonder if I could write them with less code .

Of course, the DLL is present but the app is looking in the debug folder.
