View 7 RepliesI want to create a button that when clicked on He will show the Msgbox and after X seconds more MsgBox will show agin.
View 5 RepliesSay you wanted to set a status message
' Set status
ssMainMessages.Text = msgValidating
Then perform an action that requires a http request that takes around 5 seconds then you want to display the result of that
' Set status
ssMainMessages.Text = msgValidated
It will only always display the second message? Its like it jumps the first part of the code and goes straight to httprequest.even if you put the update,system,threading.thread.sleep ....

View 7 RepliesI am creating a small applicaiton for simulating dice roll. To simulate bounces I change the position of the picture randomly. Now to simulate more than one bounce, I used a for loop to continuously change the position of the picture box. But it is not happening as I planned, the form only displays the position of the last loop. I even tried using System.Threading.Thread.Sleep(1000) hoping to show the bounces, but even they show the last loop only.
For bounceCount As Integer = 1 To bounces
bounce(pb_dice1)
bounce(pb_dice2)
System.Threading.Thread.Sleep(3000) 'I need to pause here and show the recent change in position then continue after 3 seconds
Next
the bounce method changes the position of the PictureBox.
How can I pause my for loop, display the newly positioned dices, and then continue after 3 seconds?
Is there a way to play a wav file and then pause for 10 seconds and then it will repeat? I know it will be a loop, but the part that gets me is pausing for 10 seconds before starting the loop again.

a datacontext defined in a module(domain services ado.net ria)a page having add/delete methods whenever any method is executed, it is found that all the previous actions (NEW RECORD ADDITION and DELETION OF RECORDS) are carried out before the new action is carried out normally
this behaviour is not prominent but "when using break points and inspecting the values of the variables and table object to be added to context, it is clear that all the previous actions take place again. even when the datacotext. savechanges is called, even after that still all actions carried out on the datacontext repeat themseleves, when any new action is to be carried out
I want to convert seconds such as 254565443 seconds to hours, minutes, and seconds and thought if I could remove the decimal and the numbers behind it and not change the number in front of the decimal then it would work.

Quick question - if I have a timer set to 5000 (5 seconds) and the code in the timer takes longer than 5 seconds to run because of sql stuff, will the timer wait until the code is done till it fires again?
View 3 RepliesMakes 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.

I am constructing a program, i am new to Visual Basic, but i have past programming experience. I was wondering if anyone knew how to form a loop that could...lets say calculate the answer when two numbers are added together,and it would repeat this thousands of times, etc. And if there is a way, would it be possible to calculate the time taken to complete this loop.

I have 2 forms, 1 is for control and the other is for display. Its 2 because the 1 for display will consume the whole screen and there's no space for buttons.Im trying to control form4 using form2 or some other form, navigating a certain webpage in the process.
I have this code for the control: but it does not work, what would I do?[URL]..
This should be simple, but the answer is eluding me. If I've got a Save action in my controller, and the save fails, how do I cancel the action without disturbing what the user entered? For example, Index is strongly-typed of "MyTable":
Function Index() As ActionResult
ViewData("message") = "Hello"
Return View(New MyTable)
[Code]....
In the Catch, if I put Return View(form), I lose the message passed via ViewData. If I redirect to Index, I'll lose what the user entered. I think I've seen the simple (correct) way to handle this before, but if you don't know what to search for, it's hard to find.
I know there are several ways to publish updates but I would like to know the best way to do it. What I already have configured is a shard network folder which I intend to have the program update from there. What would the best way to publish updates to the folder be?
View 1 RepliesIf my if is not correct, and it goes in the 'then', how is it possible to redo my whole sub? I want to automate a whole sub.
View 1 RepliesI have searched high and low for documentation on how to use this feature. While the loop I could write would be simple and take no time, I really would like to learn how to use this. Basically I have a class, say, Widget, with a Save() sub that returns nothing. So:
Dim w as New Widget()
w.Save()
basically saves the widget. Now let's say I have a generic collection List(Of Widget) name widgetList(Of Widget) and I want to run a Save() on each item in that list. It says I can do a
widgetList.ForEach([enter Action(Of T) here])
....but how in the F does this work??? There is no documentation anywhere on the intrablags.
I am having trouble doing something that is probably pretty simple!I have a stock listing that is done by 1) a simple form with parameters (Index) and 2) an ajax called partial view that displays the list of stock (based on the params).On this same simple form (Index) I have an action link to an "Add Stock" method which calls another form for adding stock.When the user has finished adding the stock I redirect them back to the stock list page (Index).
My issue is that I would like to "remember" the parameters that were initially entered in this form so the user isn't just directed back to a page with blank parameters forcing them to enter them again.I thought I could simply overload the Index method as such:
[Code]...
I get this error: The current request for action 'Index' on controller type 'StockController' is ambiguous between the following action methods:.Now I have read this post and it's answer but I cannot figure out how to implement the solution. Is this solution applicable in my situation? Is there a better way to acheive what I'm trying to do?
