I want to cast a String into a Cookie and add it into a cookiecontainer. For example if I had Dim cookieString As String = "variable1=hello&variable2=goodbye" Dim myCookieContainer As CookieContainer myCookieContainer.Add(cookieString.Parse(Cookie)) Something along those lines.
View 1 RepliesI add cookies to a cookiecontainer using
cookCon.add(response.cookie)
After that, how do I get the cookie in the cookiecontainer?
I tried
cookCon(0) and cookCon.cookies(0).
I want to get the cookie using Live HttpHeaders and then copy and paste it (as a String) into a textbox where my program will use that cookie to navigate through pages. Here is what I have at the moment:
Dim myCookie As CookieContainer
Dim cookieString As String = TextBox1.Text
myCookie.Add(cookieString.Cast(Of Cookie))
This is just a silly attempt I just want to ensure anyone capable of helping understands what I wish to do.

ByVal e

Can I get info from stored cookie on the local machine. I have a Webbrowser control in a winform, and I would like to output data from a cookie to a label or so.

I tried to parse string to TimeSpan like the following :
Dim dt As DateTime = DateTime.Now
Dim timeCheckin As String = Format(dt, "HH:MM:FF")
ts = TimeSpan.Parse(timeCheckin)
It threw error like this:
System.OverflowException: The TimeSpan could not be parsed because at least one of the hours, minutes, or seconds components is outside its valid range.
HI, using vs2008 and building a web app. On a asp page called blackjack.aspx, I have four labels with id of lbBJTStatusP1 lbBJTStatusP2 lbBJTStatusP3 lbBJTStatusP4.
I want to address those labels in a single sub by casting the casting two strings into the control name, so that string lbBJTStatusP & "1" would refer to lbBJTStatusP1.This is done on the code behind page.
So far I have tried this but with no success. boxct refers to either "1" "2" "3" or "4".[code]...

I'm getting this error
Unable to cast object of type 'System.Int32' to type 'System.String'.
when doing a routine LINQ to SQL query:
Return (

Where n.NewsletterID = NewsletterID

How is it possible that an Int32 can't be cast to String? How can I debug something this? Since it all happens deep in the bowels of LINQ, I can't even get any indication what field this is angry about.
i have an aplication that interacts with a http server, some tasks are performed using the web interface, but the the user has to use the application for some special features... i would like to make it "singe sing on", i was thinking about importing the IE cookies into the CookieContainer but i can't find any documentation on how to do this.

View 2 RepliesIs it possible to store entire CookieContainer in a file and then retrieve it when needed?
View 5 RepliesOn my form i have a button that logs me into my website, then retrieves the cookie and places it in the cookieContainer for use navigating the website, i have another button that needs to use the cookies that were returned, what is the best way to pass the cookieContainer over to other buttons?
if i do this and set a new New CookieContainer() in the button:
vb.net
Private Sub buttonSendMessages_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles buttonSendMessages.Click

i need to pass the .CookieContainer = CookieJar cookies that are prevviously already in the cookie jar over for use in this button.
The login process to one of my sites can get fairly long code wise, so i have decided to cut the process up into maybe 3 or 4 functions, instead of all the code on 1 page.

Is there a better way of testing if a string can be converted to an integer other than something like the following?
Public Function IsInt(ByVal value As Object) As Boolean
Try
Dim temp As Integer = CInt(value)

I read somewhere that older VB .net (pre VB .NET 2005?) couldn't use overloaded operators in a C# class. Is it true for overloaded cast operators?Either way do you guys think it's a disadvantage for a C# class library not to include them and arithmetic methods as actual methods for other languages, like:
ToDouble
ToFloat
