how to work multiple bookings into my program. At the minute i have two calendars, one visible (Start date) and one invisible, wich the user can make visible if a repeat booking is required (End date).
How would i work a repeat booking into my SQL Statement, as i only have one BookDate field and one BookDate parameter.
e.g.
Dim BookRoom As New SqlCommand("INSERT INTO bookings ( UserID, RoomID, BookDate, StartTime, EndTime, Reason) " + _
"Values (@UserID, @RoomID, @BookDate, @StartTime, @EndTime, @Reason)")
I have a basic calendar schedule i want to loop through and then do some checks. My first data reader works fine. But as soon as i put in the second data reader it does not finish.Here is my code
Dim mycommand As New MySqlCommand Dim mycommand2 As New MySqlCommand Dim myData As New DataTable[code].....
Basically the above code looks up distinct calendar entries in the database.i then loop through the entries and put the items in a list view.The code above will list about 1600 rows.in the above code if i uncomment the 2 lines the system will break It will on display one line of code. What im trying to do in the second query is to see if there are double bookings in the database.
Right now i have a form in the VB where there are 2 combobox in it. user can choose from a range of products that comes together with some description and these are to be stored in a database table.. when i retrieve these data from another form in VB, i'm only able to retrieve the first product and it repeat e same product in my second textbox.
I'm trying to make a mastermind game program with visual basic. I started of creating the combination maker for the start of the game. Hoever, in my version i don't want any colors to repeat. I used the random function independently to get numbers from 1 to 6. Each number has a corresponding color. The problem, the values still repeat sometimes.
If a booking is present in database on 12/27/2011 at 5:00 pm for 2 hours and i try to make a new booking on 12/27/2011 between 5 to 7 pm then my code generates an error message. Even if i try to book at 4:00 pm for 2 hours it generates an error message as the 2nd hour will be overlapped here with already made booking from 5:00 to 7:00.
Now here comes the problem part. When day changes it doesn't generate error message i.e. IF a booking is there on 12/27/2011 at 11:00 pm for 3 hours then it should not allow new booking till 12/28/2011 2:00 am but when i try to book 12/28/2011 at 1:00 am it saves it in the database and doesn't generate an error message. I want an error message generated in such a case.
I am using two separate fields in database one for time and one for date. Both of them have DateTime datatype.
newtime refers to time on which i'm trying to make new booking addednewtime refers to time after adding the duration to time on which i'm trying to make new booking

I'm making a timer program, that I want to be able to store "unlimited" timer profiles, that someone can load and use. Now I've created a form that you fill with data, which then gets saved to a .xml file in a pre-defined directory. I'm now working on some sort of code that will:
1. Search the directory for .xml files
2. Find any .xml files and convert names to strings
3. Store the strings in a dropdown menu, so that when one is chosen, it loads that profile.
I think I have 1 down:
System.IO.Directory.GetFiles("C:Simple Timer") Dim di As DirectoryInfo di = New DirectoryInfo("C:Simple Timer") di.GetFiles("*.xml")

I am having trouble retrieving data from a stored procedure that I have set up as a Data Adapter using VB.NET 2005. The Database is SQL Server 2000, and what I am trying to access is a simple Stored Procedure that will validate a users login access. [code] I have a dataset set up as AdjustmentsDataSetspValidateLogin. I am trying to figure out in code how I can address this using a table adapter or how I can capture from a login form I have created the UserID and pass this value to the stored proc to return the current record, if any of the user.I initially setup a Dataset and dragged the dataset onto a form. Then I deleted the data navigator and the toolbar that was created by default so that I could just pass values to the Stored Proc. I also have the table adapter setup to return a table "LoginData" with the two fields Approver & Admin when I pass a userID.But I am having difficulty addressing the table adapter in code and pulling back the data values for the UserID I'm passing to the DataSet.Does anyone have any ideas on how I can call this stored proc and get the data values returned? I'm new to .net programming. [code]
