Using Dates In A For, Next Loop

Feb 20, 2009

Why can't I do this?

For myDate As Date = startDate To endDate
Next

where startDate & endDate are Date types. It tells me 'For' loop control variable cannot be of type 'Date' because the type does not support the required operators. Is there another way to loop through dates?

Say the user specifies these two dates....

Start Date: 2010-12-05
End Date: 2011-01-15

Select January 2011 then
startdate = 2011-01-01

Evaluates Loop Condition In Do...Loop Statment To Determine Whether Loop Instructions Should Be Processed

Mar 14, 2011

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

Create A Loop To Loop The Locations Of The Platform?

May 31, 2010

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:

May 27, 2009

I'm having some trouble. I have an sql statement to update some rows to an Access DB I enter a date like 01/08/2009 (1st Aug 2009) and it saves to my DB as 08/01/2009 (08th Aug 2009 but still 01 Aug if it were mm/dd/yyyy format)

I've got:

Dim

dp As Date = Format(Me.tdate.Text, "dd/MM/yyyy")

Dim

strsql1 As String = "INSERT INTO TANKERS (REF, TDATE, TTOTAL) VALUES ('" & ref & "', #" & tp & "#, " & ttotal.Text & ")"

Difference Between 2 Dates

Feb 28, 2012

I am trying to find the difference between two dates. The first of the two dates can be changed and when it is changed, the difference between the original dates has to be retained.

[code]I have the value of the old date1(currDate) and the new date1 value(newDate). I need to get the difference between these, and then add or minus these days from the endDate.

.net - Insert A Time Between The Two Dates?

Feb 7, 2010

Using VB.Net and SQL 2005

Table1
Name FromDate ToDate
Sched1 20091201 20091231
Sched2 20090515 20090613
...,

In table2 i want to add a time for a date between the FromDate and ToDate

Table2
Name Date StartTime EndTime
Sched1 20091201 080000 120000
...,

In my application am using "AddTime" Button. In the click event i want to write a code for adding the time for the dates.When I click ADDTime Button. It should check the max(date) in table2. Then it should show the next date of the max(date) in table2.For Example Select max(date) from table where name = 'Sched1'. It should show the next date means 20091202. because 20091201 Data is there. There is no data in table2 for Sched2, So It should show the StartDate 20090515 from table1.How to make a code or query for this condition?
