Finding Difficulty In Assessing Future Warning Date?
Nov 24, 2009
I made a programme through which I get a feed back clicking a button for a future warning date. I am giving the code below so that you can givthe problem is, I have to take 12 DateTimePicker to do that job in a single form which is creating a saving problem means when I click save button it takes long time to save. Now, I thought If I can do it by using TextBoxn a date format would easeup my save problem. Or it can be MaskedTextBox as well. Below is my code if any one can give me the solution.
Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If DateTime.Now > DateTimePicker1.Value.AddYears(1).AddDays(1) Then

I have a form where a user can choose an election date. One of the most frequent errors users make is entering the incorrect due dates of reports. Therefore, I am attempting to generate the report due dates in the application using the report guidelines. For instance, reports are due 32 and 15 days prior to the election and 30 and 60 days after an election.
I know the following won't work but you get the jest of what I am attempting to do. I am assuming I will need to break down the month, day and year somehow before I subtract or add the days to the date to get the actual report date.

I need to have the Calendar Control start 36 hours after the current date. How would I do that?
I have a form that requires that the future date has to be at least 36 hours from the current date in the order for the workers involved to be able to complete the task.
check values and keep the form from processing:
Protected Sub calPickupDate_SelectionChanged(sender As Object, e As System.EventArgs) Handles calPickupDate.SelectionChanged
If calPickupDate.SelectedDate < Today.AddHours(36) Then

I am trying to flag rows in a grid in the following order based on a date column
When 2 or more days old from today
then RED
When 1 day old then YELLOW
When 0 days old then GREEN
When the date is in the future then
BLUE
I have the following which is working fine except for the future dates which are GREEN instead of BLUE.
Dim myDate As DateTime = CType(grdSummaryView.GetRowCellValue(e.RowHandle, "myDate"), DateTime)
Select Case Now.Subtract(myDate).Days
'2 or more days old then RED FLAG
Case Is >= 2

I am teaching myself VB while creating a basic application I can use at work. Is there something in VB that will calculate a past and future date from a specific date. For instance, an Election Date falls on November 2, 2011. Once this election date is entered I want the program to calculate the reporting dates. The first report due is due exactly 32 days prior to the election. The 30 day post is due 30 days after the election.

I have a text box on a form. It is a masked text box that shows in the format XX/XX.It is used for the expiry date of a credit card.What I need to do is how to take a value like 08/11 which means August, 2011 and check that it is in the future.For example something like 08/09 would be last year and hence would be invalid.Is there any way to take this string and check?

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 need to find a way to find the date (DD/MM/YYYY) of the Monday for any week we're on.
For example, for this week, monday would be 09/11/2009, and if this were next week it'd be 16/11/2009.
I managed to get somewhere in the forms of code, but all I got was 'cannot convert to Integer' errors. I was using Date.Today and AddDays().

Basically I am looking for a means within a asp.net 2.0 (or higher) application, to identify a time zone and UTC offset for a specific location and date. I want to be able to look up the time zone rules using either city & state, Zip, or LAT & LON I have an event database that tracks location, date and time for the events. Times are recorder relative to the event and the records do not currenlty indicate the timezone for the event or whether or not DST is in effect. Recently, I have encountered a situation where I need to link several events across different time zones. What I am looking to do is:
first, record a master event, say for August 13 2012 at 8:PM in New York, NY 10021
Second I need to record a related event in Houston TX.
When I record the related event I want it to automatically populate the date and time relative to its local time time zone rules. To do this it needs to be able to identify the effective timezone and UTC offset for the master event as well as the linked event so that I can calculate the correct date and time to display on the satelite program. As a future update I would probably capture the time zone /utc offsets with each program so that I don't have to recalculate the master record each time I want to add a related event.
So far I have not seen a way from system.timezone or timezoneinfo to be able to look up a timezone and the effective UTC offset of a given date and location.

I'm using Visual Studio 2010 and Excel 2007. I'm having difficulty figuring out how to convert an office excel project into a vb.net project. I wanted to take the ugly windows 98 style buttons I currently have in my spreadsheet and replace them with controls on a new tab on the ribbon. I can make it that far, but I didn't anticipate the large gap between languages.
The code below is supposed to take a bunch of information from a windows form and insert it into a new row on sheet12, sort the table of info, and name the range. Right now visual studio show no errors until I actually try to run the code at which point it says "Object reference not set to an instance of an object." regarding the code "oSheet.Rows("1:1").Copy()" I don't think I understand declaring my variables in vb.net.

In my tic tac toe game I'd like there to be three different levels; easy, medium, and impossible. There are 2 forms; the difficulty level form and the main game form. When the game first starts the user will be prompted with the difficulty level form which contains 3 radio buttons; easy, medium, and impossible.
I've coded three different functions based on the difficulty level; easyMove(), medMove(), and impMove(). These have all been coded in the main game form. How could I run the respective function based on the radio button that was selected in the previous difficulty level form?
If it was on the same form it wouldn't be a problem but because it is on a different form I'm unsure of how to do this.

Okay, i've tried httpwebrequest, webclient, and a couple of others methods; using the headers parameter of each to set headers and then either opening a response stream or simply setting the system.net.webclient method to download a response into a string. Put simply, how do I make a simple GET request with a few headers and read the data back! I am very, very stuck in a hole right now..

I'm not sure if this is really a VB IDE issue, or a more general VS10 issue, but I couldn't find any other relevant category to post in, so here goes!I have several VB projects which I want to use in the same solution in Visual Studio 10. I created a project (& corresponding solution) which will reference them and added the existing projects by right clicking the solution in solution explorer choosing 'Add->Existing Project'. Then I went to the containing project's Properties window and added references to the existing projects, so they could be used by the project.

I'm having a strange difficulty. Here is the order of events:User presses button on form1 New Form object is created for from 2 New form object '.show' command is fired Form 2 opens correctly In the Load Event of Form 2, the form attempts to do various things in a try, catch, finally clause On catch, I close form2 down '.close' as it cannot be used as something has gone wrong with the execution However, my problem is this. It is acceptable for things to go wrong on the from 2 load event which is why I have implemented the try - catch functionality. However, when I close the form2 down as a result of the problem, a real error ocurrs 'Cannot access a disposed object' and the VB IDE refers me to Form1's '.show' event for Form2.
It is almost as if the form hasn't fully 'shown' before I am closing it down. Does anyone have any idea what the problem is here? Do I need to close down Form2 ourside of it's Load event handler so that Form1 thinks it has loaded correctly?

Recently I started a project with the goal being to have text that was inputted into a textbox stored within a three dimensional jagged array. The idea is that every time a button is pressed, whatever text that is inputted into the textbox is split into separate elements, where each word occupies its own element in the array. So for example, if a poem were entered into the textbox and the button clicked, each word of the poem would be assigned to a discrete element in the vertical dimension, and each line of the poem assigned an element in the horizontal dimension. After the text is stored into the 3D jagged array, the text should be cleared from the textbox and a counter should then ensure that on the next button press, the new text inputted into the textbox is stored in a discrete element of the array. Below is the code I have written so far, but I know that I am far from having anything might accomplish what I have just described.

I know the WOW environment is currently shipping on Windows 7 and 2003/2008 MS server products to enable the use of 32-bit applications. But does anyone have any thoughts on whether they are going to provide this environment on PC and server operating systems beyond Windows 7?
I know that the runtime files (DLL, etc.) will not be provided beyond Windows 7 for 32-bit VB 6.0 applications to run on.

I have the following Query:
SELECT *
FROM tbl_Muffins
WHERE OvenLoadId IN (
SELECT OvenLoadId
[code]....
The idea of the query is that I want to specify an OrderId, and I want all Oven Loads that have items from that order in them, as well as ALL OTHER ITEMS in those loads, even though they could be from other orders.The query works as expected, but I'm not able to use it for my Crystal Report I've written it for.I have put this query into a User Defined Function, however I'm unable to use a call to that function as a table source in my Crystal Report. I am using Visual Studio 2003 (I know it is old, the client refuses to upgrade).
