I have the following
[Code]...
and as you can see, I am showing users the next available date open to them is determined with the value dteReturnValue.ToShortDateString .. but what I'd like to do is show the user both the start date and the end date, which will always be +7 days from the field in my database.
I have two tables: a schedule table that contains information about how an employee is scheduled and a numbers table in which each number corresponds to a date.
[Code]...
I can do this on the SQL side or the code side. I have Linq at my disposal if I need it. The table doesn't need to be compiled by SQL. This will happen dynamically on a website and should be as efficient as possible.I don't want to have to iterate through each and look for breaks in contiguous days if I don't have to.
I am trying to get a list of dates from a provided StartDate and EndDate in my database, and use these dates to link to dates in a database (to display another variable on the y-axis of the chart) and to populate the x-axis of a chart (with the list of dates). Is it possible to get a list of dates in VB and pass them into a chart this way?

I have a form that collects user parameters to print a report. There are two DateTimePickers to let the user select a date range for the report. The selection of a date range is optional so I set the From picker to a date before any data could be present. If the user wants to select a date range, the from field is set to a very old date so it takes a long time to get to any current dates. Whe I'd like to do is when the user drops down the picker, reset the date to today and let the user scroll from there.I tried the dropdown even in the picker, but the new date doesn't get set until the user has already selected a date. Any suggestions on how to get this type of UI behavior? Also any better suggestions to streamline the process?The main objective it to collect from and to dates from the user is they want to select them and collect wide ranging dates if the user doesn't enter any.

While the application is running, if i have any of these forms open and i switch over to any other application other than this and when i come back to it, all these forms hide. I cannot reopen it or see it anymore.. Why is this happening?? how can i sustain these forms as it is even when i leave the application.LuxCoder

View 6 RepliesI've just upgraded from Visual Basic 6 to Visual Basic 2008 Express Edition.
1. Show anothor form (ie. Form2)
2. Close Form1.
At present when I use the me.form1 , but both Form1 and Form2 both closes.I would like to press a button or on a timer, to show Form2, while closing Form1.
my scenario is this: I have two forms and a module. Let's call one of the forms MainForm and the other SecondForm. My module is running on a seperate thread to MainForm. A sub routine is triggered in the module, and I want it to display SecondForm.
I understand that I cannot do this directly because SecondForm needs to be called from the UI thread, which is shared by MainForm. How would I go about doing this? I'm guessing that I would have to use a combination of invocation and calls to MainForm to activate SecondForm.
Well I accidently double clicked both of my forms in a project and then they weren't pinned anymore so I exited them out hoping they'd be pinned aghain, but now when I open the project, no forms show up. Just blank blue wall... How can I get the forms back?
