1> how i'll take the input as time:hour from text field?2> how i can save the calculated time in database for use in other page?
I am selecting time from dropdownlist. and want to convert it in datetime and store it in database. When I am converting it to Datetime using following statement.
I need to store time in database and then show in using gridview.I wonder how to store and show data so that user will see correct datetime depanding on his timezone?
i'm a quite new in Ajax technologie.The feature of the MaskedEditExtender and its -validator is very helpful. But i have some problem with it.If i try to make a textbox with MasekdEditExtender for time input, so i can give a invalid time e.g. 25:60 and there is no error message of validator.So, how can i avoid inputs like 25:60? As we know the time can take values between 00:00 and 23:59.
I'm creating a website with ASP.net and I have a sign up page. The user has to enter a name and password in textboxex, and choose a location and reason for joining from dropdown lists. (There is a built in wizard for new user sign-up but I chose not to use it).I would like to save the information entered in a table in a database in the App_Data folder. How do I do this?
Is it better to store images directly in a database or to just store the name of the file in the db and display that file? I would think that just storing the filename of the image would keep the db size low...
Creating a system with web front end and SQL backend (microsoft obviously). I have tried using the asp.netsqlprovider but i can;t as i am only allowed one database on the server, so i then tried to update my current database with the triggers to input the schema into the already existing database.Next step i create my own table with two simple fields of username and password and try and authenticate that way, i can't get that to work either.
I ahve limited permissions on the network as i am a University Student. I really don't know what to do. Never had to create a log on system before and i thought it would be far simpler than this. I ahve used Microsoft's sqlprovider schema before and it worked fine. I have also authenticated via IIS and AD too before. I can't do any of those two in this instance it seems.I need an alternative for logging in users, if needs be in can be crude. I also still need to have some kind of two different views too for logged in users and not logged in users, but that can change if needs must.Don't let me down people, haha. Think this posts in the correct place, i could not find another one i thought could be more relevant.
I have a table which contain products, I want each record in the table to have an image. I've created the field with the datatype image. How to I manually add image to the table ?
I am trying to store data from an XML file to a table in my database, but I keep getting the same error.
This is my code from the cs file:
[Code]....
And this is my error:
Violation of PRIMARY KEY constraint 'PK_Areas'. Cannot insert duplicate key in object 'dbo.Areas'.
The statement has been terminated.
In my XML file I have both existing rows and new rows for the database table. I'm guessing I have to do something to sort out the the rows that are not already in the database, but so far I have been unsuccessful to figure this out.
my problem is my asp.net and C#.net application should read flat files(.txt,.doc) from folder automatically and read the data from file and stored into database
my file like this :
BNK20100312APPHU6658994 // BNK,20100312(date),Ap,PHU6658994 So we have to store these.. BNK20100312APPRU5104220 BNK20100312APPRU5761800 BNK20100312APPZU3739288 BNK20100312APPZU4454037 BNK20100312APESU2552894 BNK20100312APAXU4302543 BNK20100312APCKU1613369
On a website I'm building user's can subscribe to newsletters by entering their email address into a form and submitting. This will then add them to a 'Newsletter_Subscribers' table in the database.
Users can also sign-up to the website by entering their username/password/email details. They also have the option of subscribing to the newsletter. If they choose to do this then their email address is added to the 'Newsletter_Subscribers' table.
However, I wish to make the data more consistent rather than storing the email address into two different unrelated tables in the database.
Has anyone tackled this issue before, and what is the best way to go about storing this information?
One idea I had was to have a 'Users' table, a 'Users.Members' table and a 'Users.Subscribers' table. All three would have a relating UserID column, with the email address stored in the 'Users' table but I'm not sure this is the best method as I would also wish to store the Username/Password in the 'Users' table in case we had a 'Users.Advertisers' table for example.
I have to create a simple application which scans, displays and stores the info from a barcode. I have been able to sort the scanning and display part of this application but I need to know how to store the infromation entered into a textbox to a database and then be able to display the stored data as a list at a later stage.E.G. Once the "STORE" button is clicked, the information/text within the textbox is stored to a database. Once the "VIEW STORED DATA" button is clicked, the stored information in the database is displayed as a list.I am a complete beginner when it comes to creating web applications using asp.net. Also, the type of database to use (i.e. sql, wamp.etc) and how to link it to my application is also puzzling.
I'm working on an application (a web application, asp.net and c#) which is datetime-dependent, so, based on the current date, it will launch forms for the logged user to fill in.
I've been thinking about how we're going to simulate real usage of the application, for debugging and testing purposes.
public class MyDateClass { private DateTime _currentDate; public DateTime GetCurrentDate() { // get the date, which may be different from DateTime.Now return _currentDate; } public void SetCurrentDate(DateTime newCurrentDate) { // set the date to the value chosen by the user _currentDate = newCurrentDate; } }
allowing me to set the current data, by invoking the SetCurrentDate method, for example, in the code-behind of a link button and a calendar input.
how should I exactly store the DateTime variable, throughout all the application? I can't work with the session in this class, right? Should I work with the Thread?
I use a calendar to pick a date that I want to store in my MSSQL Database. I use the form format, like 2010-01-27 (european date format) with no time info. What MS SQL Date-type should I store this date in?

i've got some problem reading excel files to store into sqlserver database. currently my code has a fileupload control and a button for me to save the excel file into a folder and read the data inside the excel file and write it into the sql database. The code works only if the excel sheet name is Sheet1.xlsx, however i tried upload a diff file named ImportUserFile.xlsx and it gave me the exception below. 'ImportUserFile$' is not a valid name. Make sure that it does not include invalid characters or punctuation and that it is not too long. i have also tried other file names and it seemed only Sheet1.xlsx works.
