Okay my assignment is to change a code up using two functions instead of a subprocedure to calculate total rainfall and avedrage rainfall and then to add a startover button to the application which not only clears all the labels but also clears the counter and accumulator. This is what I have gotten so far my functions do not work and I can get the labels cleared. I just can't get the counter and accumulator to reset back to zero
View 1 RepliesIn the first loop once it cycles through once it does not reset the data so it continues to hold the previous data so therefore the outcome is incorrect. Can I reset it to start back at 0?

We've set code to fire certain valves on the timer but once it gets to the last valve (checkbox) I'm not sure how to reset the timer to start back at zero so that it refires the sequence.
Here's the code:

ByVal e As System.EventArgs) _

Here is my case:I have a richtextbox called Rtb1 I have the text property for this control set to "ThreadAmountEdit=[Thread Amount]" This was set through the RichTextBox Tasks function, by clicking the control and selecting the little arrow in the top right corner. In working on my form, I edit the text "[Thread Amount]" of the rich text box to "45". What I need is to be able to reset Rtb1 back to default ("ThreadAmountEdit=[Thread Amount]")on button click.
I've tried: Rtb1.Refresh() which doesn't appear to do anything I've also tried Rtb1.ResetText() which completely clears the textbox.
In Rad Datetime picker,when selecting any date in February always set it to date in March.
View 2 RepliesThe gist of the program is to:
- Read a CSV file into an array
- Get this visible in a list box, so the values can be:
- Sorted
- Edited
- Deleted
- Added
- Finally save these manipulated values back to the text file
Would love some suggestions and code as to how to get this going, hopefully I'll get the hang of it and come back and fourth for help
i want to check the value date of the date time picker and add 5 days to the current date it is displaying
View 3 RepliesI have a mvc 3 vb.net razor App that I need to redirect the view to a different action if the link is not clicked on between a preset range of Month/Day/Year ranges.This is needed to limit registration for a school semester to only be able to be performed between and Open Registration Date and a End Registration Date.I am thinking I can simply put this in the controller function in the form of either a If Statement or a select case and then use redirect based on the condition of the date..Is there some simple short code to use to perform this test.My variables for the dates are OpenDate and EndDate.[code]

I got a situation where I need to update the details of an order. So there is an order, and there are many products in that order, and the way I am updating that bit at the moment is simply 'delete and save'. But what happens is that it deletes first and them saves products which would be fair enough but if anything in save function goes wrong the order leaves with no products. So how would I know if I will get an error?
View 1 RepliesI'm reviewing some code in VB.net, and in a validation object they have written the following
If Not IsDate(Entity.SelectedDate) Then
ErrorList.Add(New CValidationError("MainReport", "Please select a weekend date"))
SelectedDate is of type Date. It seems to me it would be impossible to ever hit this condition. Is this true?
How do you set the back color for a date picker control in vb.net 2008? There is no back color property like on a textbox.

The idea is to be able to clear and reset all of these by clicking a reset button.

But ofc Me.controls isn't gonna get involved with the stuff in the groupbox.
I am developing c#.net solution where i have to calculate Start Date based on provided End date and Duration (back days) without weekends.

Start Date = 29/04/2011
I'm trying to do some validation testing in VB.NET. If Entity.WeekEndDate.ToString = String.Empty Then ErrorList.Add(New cValidationError("id", "Incorrect Week End Date"))

I have the following query that should be bringing back a single date, however, it is bringing back the first date in the table, completely ignoring the Where clause.

Recently I've created a window database program(Tools Inventory); everything works fine except for the following two :
1. It doesn't accept modifications to the existing datas in the column & rows. (Error : Updates require a ValidCommand......)
2. Remove button does not delete the data in the database. It only works in the runtime.
I want to make a program where I load in a file in hex format and have a number of check boxes where if selected then certain hex values change.
So it would search for offset d5dc and change the last 4 values to 00 E1 F5 05 and then then same again for other check boxes with different offsets set to each one.
Not entirely sure where I've gone wrong with this, basically the problem is I have an access database linked and currently I can create new entries successfully but when I edit a record and the user attempts to save back to the database it throws up the below error.[code]...

On my add button i still have to add codes that disables my navigation buttons and and my search button... and add codes that will enable them in save button... im still new thats why my codes are just simple if, else if, else conditions that just manipulates enable, visible, text, properties..also if i search my data will be search but my textboxes only shows the searched data.. i still have to add button that will only be visible if the program finds a data... and this button function is to remove the filter..rather than disabling some functions i want a messagebox to prompt the user that this functions arent functionable...
Look at my codes... i find it lame... its kinda irritating always just using True and false..
