Pause In Code Can't Use Sleep Function?
Jan 4, 2011"'I'm having an issue sorting out why my code isnt working. When I "step into" it line by line i can get it all to work exactly how I want, however when I actually run the macro i get an subscript error 9. The code basicly sets a .CSV url to a variable "CurrentURL". The code then launches this url which opens a .csv window called table.csv. I want to copy 2 columns off this window and paste it to another document called "MPT_CAPM_v1", then close table.csv. Here is my code the red line is where I believe I'm running into my error.'This macro opens a URL, copies and pastes the price data into the sheet
[Code]...
I think the error may be caused by the fact it takes about 4-5 seconds to open table.csv in excel, and my line of code is trying to select a window that isnt currently open. After I get the error message, table.csv opens up. I've tried Loops & Sleep functions to try to input a delay, but regardless it seems that table.csv will not open until the end of said loop or delay.
VS 2010 Pause / Delay Code (can't Use Sleep Function)
Aug 26, 2010I have another problem with my bot.
[Code]...
After the 7th line I need a pause until a submit button pops up on the screen. The submit button is hidden until the getelementbyid.focus is run. I cant use webbrowser_documentcompleted because the submit only unhides itself, and I cant use Sleep() because that just stalls the whole block.
VS 2010 - Using System.Threading.Thread.Sleep(5000) To Let My App Pause/sleep For Some Time
May 25, 2010Currently I'm using System.Threading.Thread.Sleep(5000) to let my app pause/sleep for some time. This works great but I can't open my app anymore when it's sleeping and it uses about 25% of my CPU. I guess there must be a better way to do this. I also tried using a timer but that didn't work out to well for me..

VS 2008 Associate A Timer To Function?
Mar 8, 2012I want to associate a timer to my function. Actually what i am doing is that i am tryin to store certain values in a database. A function is such that it calculates 5 values and stores them in a database. While storing them in the database it displays them in a textbox on the form. Now i want to display them one by one which it does. But it does it so fast that i can only see the last value that it enters in the database inside the textbox. Can i make it show all the values slowly one by one.
View 3 RepliesNon-locking Sleep/waitfor/delay Function For ASP.NET?
Apr 27, 2011I am writing an ASP.NET class that interfaces with an external application. The flow of the transaction between the web server and this application is as follows:My object writes a file to a directory.The outside application detects this file and processes it. This can take between 1-5 seconds.The outside application writes a response file to the same directory.My object detects the response file and parses the results.The 1-5 seconds it can take for the external application to process my file is my problem. The most straightforward way to wait for the file seems to be something like this:
Do While Not File.Exists(f)
Thread.Sleep(500)
Loop
Of course, Thread.Sleep() completely locks up the rest of my website until the outside application processes the file. Clearly, this is not a workable solution.How can I effectively "wait" for my file to be processed without locking up the rest of my website?
Sleep Function While Processing Window Events
Feb 18, 2010I wrote the below function to sleep, while processing the window events. It works well enough, but I'd like to improve the accuracy of the sleep. Example - If you call it with 10 msec (0.010), it can take up to 15 msec of real time before it exits. How to make it closer to 10 msec?
Public Sub Spin(ByVal TimeInSec As Double)
Dim tsStart As TimeSpan = Date.Now.TimeOfDay
Dim tsNext As TimeSpan = tsStart
Dim TimeSlept As Double = tsNext.TotalSeconds - tsStart.TotalSeconds
'wait for Time seconds

Aug 20, 2009i made this code
VB.NET
Dim iString As String
If My.Settings.IPBank.Count = 30 Then
MsgBox("You alredy have the maximum amount of IP Addresses stored, delete one to add another.", MsgBoxStyle.Information, "Program Error")
[Code]...
I want it to check all of the items in the my.settings.ipbank which is a stringcollection. Before it adds and if it already exists in my.settings.ipbank then i want it not to add it. But it just adds when i run it. And then once its added it says: "Collection was modified; enumeration operation may not execute." But also before i run it. There is a warning saying: Function 'AddTo_IPBank' doesn't return a value on all code paths. A null reference exception could occur at run time when the result is used. Is this something to do with it? I think i have the Next in the wrong place .
How To Pass A Function To A Function Is Functors/function Objects Avaiable In VB2010
Oct 12, 2011I want to make an numerical integration method with takes in an analytic function and integrate it over a specific interval. For the numerical integration procedure I want to use some procedures in nr.com. The problem is that these are programmed in C++ and they uses functors to pass a function to the integration method. How can I do this in VB 2010?
I want to initialize the function (i.e. set a=1,b=0 for function y(x)=a*x+b) and then pass the function to the integration method. Then when the integration method call the function it only calls the function with one parameter (i.e. x since a,b is already set)
What is the best way to do this in VB2010?I want to make a general integration method where I can pass any single valued function and integration limits.
I have just started using VB, and from what I have found so far it seems like the tools you have is
- to us a delegate for the function
- to use a lambda expression for the function
- send a pointer/adressOf
- to create a function class/structure and submit this to the function
As for now I am most inclined to create a function-class. But I am not really sure how.F.ex. I make different classes for each "uniqe function" I want to integrate, but how can I pass them to the integration function when I need to specify the argument type in the integration-function-call?This seems like a basic problem which applies to many Math operations, so I think it would be very useful to clarify this.

View 9 RepliesFunction Syntax - Call A Function With 2 Arguments When The Function Is Only Defined For One
Apr 1, 2010I'm trying to undersatnd the syntax of calling a funciton and it seem confusing when I'm using a web service in ASP.net. Maybe this question should be in an ASP forum, but it is a VB question. This simple web service allows you to type in your name and it response with an alert box with you name.
My question is, How can you call a function with 2 arguments when the function is only defined for one. I understand that the second argument is actually a method that handling the respons, but how can you interchange function arguments for methods and how do you know that there are methods for

Difference Between A Readonly Property Get() And A Function?
Aug 21, 2009It seems that in the following example, TestProperty() and TestDouble() are functionally equivalent. Is the case? I usually use Property/Get when I have a single line "Return Variable_" type of "function", and Function when I have a more involved thing going on. Is that reasonable?

Difference Between Parameterized Property And Function?
Mar 15, 2012I am coming from the C# world to VB.NET and this puzzles me. Why are there 2 ways of doing the same thing? or is there some difference I am not aware of? What is the difference between the following:
Public ReadOnly Property Test(ByVal v as String) As Integer
Get
Return SomeOperationOn(v)
End Get
End Property
And
Public Function Test(ByVal v as String) As Integer
Return SomeOperationOn(v)
End Function
When do you use one as opposed to the other?
