Winforms - Store The Persons Username In Some Form Of Global "cookie"?
Jan 29, 2012
Ive done a login in vb.net (Visual Studio) which works like a charm. However, i need to store the username of the person that has logged in, in some form of cookie. How can i store the persons username in some form of global "cookie"? It will be cleared when they log out or the program closes PS. I dont literally mean a web cookie - just not sure what else to call it. Just a global variable which will store the current user.

I have a app with two functions. The first function use http post to log into a website. The site gives a cookie once I login, and the function have CookieContainer() to catch the cookie and then it proceeds to update my profile. I then use a second function to visit a different specific page on the website so I can grab/scrap the specific page's source code, but it appears that the script is no longer logged into the site. I see source code for a login form instead of the target page's source code. So the cookie must not being kept for the second function to be able to grab the target page source.

I have a Windows Form application that has a global error handler to display unexpected errors.
Namespace My
Class MyApplication
Delegate Sub ProcessParametersDelegate(ByVal sender As Object, ByVal args() As String)
[code]....
1) for the same deployed code, I SOMETIMES get line number in the displayed StackTrace error message and sometimes do not, even when the error message includes source code that I have written rather than a referenced binary. The project is compiled with a DEBUG configuration.
2) The application strangely minimizes to the tray when the error occurs (I thin it is unlikely that anyone can diagnose this issue w/o my more code posted, but I'll mention it anyways)
3) When I try to intentionally raise an error by, for example, dividing by zero hoping to test by global error handler, I get a dialog error message from the interactive debugger rather than jumping into my global error handler (which i want to debug because there is more to it than I posted.) Do you have any idea how to triggerand force teh execution of the global event handler?

Which is the best way to store global variables, in My.Settings or My.Namespace. The reason I ask is because I need to know certain boolean values if certain forms are open from other forms. At present I am defining Global Boolean variables in My.Application, which give the result I require.

I'm a newbie in visual basic. I'm doing a login system. I'm done with the GUI. but for the programming part, I want to know where to store new user's information along with the username and password. I've done research. seems like it has something to do with database. p/s: I'm looking for high security in storing data to prevent hacking.

I have a WinForms dialog box that contains 3 radio buttons. I am using ApplicationSettings to bind the Checked property of each of these RadioButton controls, but it doesn't do what I am expecting it to do. Now I have to click each radio button twice before it gets checked and the selected radio button is not being persisted.Is there a line of code I need to execute when the form is closed that saves the user settings?How do I eliminate the need for 2x clicking on the radio buttons?Is there a better way to persist this type of user setting? I do have a public property on the dialog box class that gets/sets an enum value based on which radio button is checked, but I didn't see an easy way of binding that property to a user setting. Should have specified that I'm using vb.net. I think that means My.Settings instead of Properties.Settings.

I want to make something thats quick & will allow me to see someone elses screen at 60fps/30fps on LAN since LAN is really fast or 10fps/30fps/60fps over internet. Of course depending on the the computer & internet speeds & everything it will vary how good it works but i'm trying to do it over computers with really fast network/internet speeds & computers, other ways to do it given to me have been really slow, I couldn't even make my app display the picture at even as much as 10fps & that was without sending it over for another computer to display & displaying it in the same application.

I am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.
So far I have this --
Public Class Form1
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Me.Close()

I have a main form with 2 splitcontainers. On the left is a richtextbox showing the clients details and how many active tickets they have open and cmd buttons which opens different uc's within the container on the right.What I am attempting to do is when a client raises a new ticket, that the global variable holding the ticket count number updates via a procedure and updates the richtextbox on the main form.The line of code that runs within the UC is:
formMain.SplitContainer3.Panel2.textUserDetails.Text = FullNameSQLString & vbCrLf & UserDepartmentSQLString & vbCrLf & vbCrLf & "You have submitted " & Global_FCRCount & " ticket today."
The part I have highlighted errors with the following reason: 'textUserDetails'is not a member of 'System.Windows.Forms.SplitterPanel'.I have checked and double checked the form names etc and textUserDetails definately exists within formMain.SplitContainer3.Panel2.
