I'm trying to check a few accounts on a website using web requests. It stores the authentication cookies and the problem is i can't get it to "logout" so to speak. It needs to logout by clearing the cookies since you can't exactly "navigate" to the logout URL.I got a bunch of code but this is the cookie bit:
Dim TempCookies As New CookieContainer
Dim logincookie As CookieContainer
and...

I'm working on an email application atm, and a main feature of it is that it allows someone to enter multiple email accounts and all of the emails will be aggregated on the one form. It would be quite easy to log out of each account if I could delete the cookies. I've tried looking in the "RoamingMicrosotWindowsCookies" folder, but there are no files at all in there, so I have no idea where the cookies would be going.
So, my question is, does someone have a function written that will delete all of the IE cookies currently in place? I can already clear the cache, but I really need to figure out how to delete the cookies.
I am in need of a method that will clear all of Internet Explorer's cookies.

View 1 RepliesThe code below tries to clear the cookies for all domains once a user logs out of the system. For some reason, only the last domain in the array is cleared. Why does this happen?
For example, if I change the size of the array to 4 and then change the for loop to only go to 3, then it only logs me out of y.xcv.com.
As a sidenote, I have this loop working on a different server that uses a slightly different function to clear the cookies.
Edit: Code updated per suggestions below. Now it fails on the "as HttpCookie" line. Do I need to include some library?
Dim aDomain(12)
Dim ESidCookie, WIdCookie, EBidCookie, TSidAccessCookie, PSidAccessCookie, SSidCookie As HttpCookie
[Code].....
I use this to delete cookies
System.Diagnostics.Process.Start("rundll32.exe", "InetCpl.cpl,ClearMyTracksByProcess 2")
works fine I checked the folder myself it deletes all .txt files.
But here Is the problem lets say I log into hotmail, Clicked the button to Clear my cookies. And navigate to log in page again, It will navigate me straight to inbox just as if I have cookies but the folder doesn't have .txt cookies file. just (index.dat). Is this means we must restart the program to this to take effect? (Works if you restart it) If so, how can I turn off webbrowser1 for a sec and turn it back? or something like that just to make sure it takes effect without me reopening the program.
I am trying to have a DateTime variable which is in a MM/dd/yyyy HH:mm:ss format convert to dd/MM/yyyy HH:mm:ss. I am using VS2008 Pro, and when I create a var:
dim dt as datatime = datetime.now It automatticlly defaults to MM/dd/yyyyy. No matter if I convert, parse, use globalisation or anything... convert to a string, which works with dd/MM/yyyy, but the minute i move it to a DateTime var type it goes back to MM/dd/yyyy I need to use this date/time to insert into a MS SQL Database and the colume is datatime type. But also is part of the app.I do not want this to be a string, I can do that, but I do need it to be a datatime in the correct format (dd/MM/yyyy HH:mm:ss)
How to clear WebBrowser's cache/cookies?
View 1 Replieswhat a good code to delete my "Webbrowser1" cookies (not my IE7 cookies !) I would also like this program to delete the Webbrowser1 History & Temporary Files as well, but mainly the cookies. I would like for this program to either delete cookies by a simple click of a button or to set a timer that can erase the cookies every few minutes. Also, if it could show the current cookies before being deleted.

In all my previous vb programs I've used the webbrowser control to do things. I'm starting to use the httpwebrequest. So what I'm trying to do with the program is log in to [URL]..This may seem really easy but I'm having issues with the cookies. Once I'm logged in I can access any pages on the subdomain my.ign.com but the second I go out side to something else I'm logged out.
Is there something that I need to change in the cookie? Below is my code so far

I just started learning programing if you can call it that, i had a class on visual basic a while ago and i managed to create a nice little application now i want to implement a menu button which when you click will erase all data in all textboxes
So i managed to create a buton but although i have found many answers to my question on the net not one code had worked for me, even the one from this forums faq doesn't work. If is probably coz i don't understand where to copy it or i am doing something wrong

This week I am doing a simple addition, multiplication calculator and am having a little problem clearing data and resetting the enter button. It is supposed to keep the add and multiplication buttons disabled till the user has entered two numbers into the list box, then you are able to choose between addition and multiplication. What I am trying to accomplish is once I hit the clear button the enter button becomes available again to enter numbers into the list box again and do the whole thing again.

I am using Visual Basic under Visual Studio 2010 Professional and I selected .NET Framework 4 from the New Project Screen. The program will plot Strange Attractors and I need to set and/or clear pixels.I delcared the following
Declare
Function
SetPixel Lib
"gdi32"
[code]....
I can set pixels by using the following code, where intX and intY ade dimensioned as integer and &HFF00 is the Hexadecimal for red.
SetPixel(hDC, intX, intY, &HFF00)
After I finish plotting all the points I want to clear the screen back to all black or white or any predifined color. I was able to do this in earlier versions of Visual basic by using "CLS" but this is not available in the current version. how to clear the screen? Should I use one of the earlier versions (.NET Framework2.0, .NET Framework 3.0, etc, etc)?

What I have is on my form there are several text boxes. These text boxes are for user input and attached to each text box is a Private Sub txtBox1_KeyPress function. In that function I have some validation code to check that the user is inputing only what I want them to. And if it doesnt it will pop up a message box telling them so, then it is supposed to clear the text box so the user can try again. But no matter what I try, the text box does not clear it still keeps the last character typed (the invalid one).
Here is the code for one of the text boxes.
Private Sub txtLanIp_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtLanIp.KeyPress
Dim strEmpty As String = ""
If Char.IsDigit(e.KeyChar) = True Or Char.IsPunctuation(e.KeyChar) = True Or Char.IsControl(e.KeyChar) = True Then
'do nothing
[code]....
The commented methods at the bottom are some of the other things ive tried to make this work. The txtLanIp.text.clear() is what ive tried from the beginning. I have also tried setting the text to "", I even created an empty string and set the .Text value to it but no matter what it wont remove that character. I have also tried various trim(), len(), Select() functions, most either give me an 'index out of range error', a 'length cannot be less than zero' error or a general ExceptionOutOfBounds error. I am just tearing my hair out as to why the simple way doesnt work, there is no logical reason why and it gives no error it just doesn't clear the box.
I have also tried moving the validation to a _LostFocus but e.KeyChar isnt a valid method or property for that declaration, which doesn't surprise me but I wanted to try everything.I dont see how it would matter in this case but I am running Windows XP Pro SP3, though I also see the same behavior in Windows 7 64 bit ultimate sp1 and windows 7 64 bit pro.
When .Clear() is invoked, is the memory freed up that was allocated when all of the items were added? I need to load several lists of codes from a database depending on the import selected by the user. Each list of codes will be a List(Of String). My idea is that I will load only small strings into a List(Of String) along with a List(Of <class>) for the data I will be validating and manipulating. When I am done, I want all of the data from the Lists to be purged from memory. Will .Clear() take care of that or does the memory still remain allocated and have to be dumped by the OS once memory gets full? (And, incidentally, what causes the OS to decide which memory blocks to dump? FIFO concept?)
There are so many lists, I'm not sure if I just want them sitting in memory or not. Granted, the lists will just consist of a single string value for each code pulled from the database. So there won't be a ton of data, so maybe I could just load all the validation lists at the beginning of runtime and only worry about purging the data List since it will contain between 35-50 "fields" per record and there will be a couple thousand records each import that is run. I don't want my program to actually cause a hit in performance in the long run. I ultimately don't see a problem because I won't be running millions or even hundreds of thousands of records at once, but I just want to be sure.
way to clear textboxes in VB.Net and what is the difference between the two methods? I have also seen people be critical of folk using clear objects on their forms and i can see why but in this case, i am only learning.
txtbox1.Clear()
or
txtbox1.Text = ""

View 1 RepliesIn my winform program (in vb.net) I wrote:
Dim dt As New DataTable
'Get data from DB into dt

[Code].....
But when I run the program, Clear() cleared both dt and dttemp! Why? Aren't dt and dttemp supposed to be two distinct instances of DataTable?
(I finally found a solution - dttemp = dt.Copy() instead of dttemp = dt. But I still can't see why Copy() was necessary in this case.
