CrystalReportViewer1.ReportSource = report
CrystalReportViewer1.Visible = True

End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim ostream As System.IO.MemoryStream
ostream = New System.IO.MemoryStream

Not using asp login in Login Control

I have the Login Control on my login page. I implemented my own authenticate method so that it fires up a stored procedure in the DB to check the password. But when i punch in the correct password, it says my password is not correct. In my authenticate method, i simply output "user logged in" on a label. How do i make it so that the control itself reconizes that the login is sucessfull?

In your handler for the Authenticate event, make sure to set the .Authenticated property of the passed-in AuthenticateEventArgs argument to true if the user is successfully authenticated and false if not.

This example will authenticate a user named "bill" with password "evans" successfully; any other combination will be unsuccessful.

void OnAuthenticate(object sender, AuthenticateEventArgs e)
{
  if (Login1.UserName == "bill" && Login1.Password == "evans")
     e.Authenticated = true;
  else
     e.Authenticated = false;
}

I am creating a login sreen for my application. The usernames and passwords are stored in a mySQL database. the passwords are encrypted by the AES alogorithm (using AES_ENCRYPT(str,key_str) function in mySQL).

Whats the best way to check if the passwords are right?

Should i throw LoginControl.Password to a SQL statement and tell it to encrpt it to see if it matches the password in the database?

OR

Should I decrypt the password from the database, and then match it in my C# code?

OR

Should I encrypt LoginControl.Password using some AES algorithm method(maybe defined in the .net framework?) and then match it with the encrupted pass from database?

OR is there any other secure way?

thx thx for advice Big Grin | :-D

Hi there,
IMO, you should store the encrypted password with salt in store, and when validating the password provided by the user you can compare the encrypted value of the password and the one persisted in store. Here are some good guidelines that you might be interested in:

http://msdn.microsoft.com/library/en-us/dnpag2/html/PAGGuidelines0001.asp[^]
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnpag2/html/paght000012.asp[^]

Also, you might also want to have a look at the source code[^] of the membership provider to see how it is implemented.

I have IIS running on my local machine. When i run this on my local machine everything works beautiful. When i upload the files to a remote webserver (earthlink web hosting) I receive the error at the top.

Now i have been reading around and googleing and everything else and others have said that i need to build the application. I have built the application by clicking build / build page (website)

Then upload the two files back up to the web server but nothing changes same errors.

Then i read something about refrences and .dll files located in a bin folder but i cannot locate these files at all nor the bin folder.

If i need to get the bin folder on the remote web server where do i find it also where do i find the .dll file after a build.

<b>Someone please give me step by step instructions of what i need to do </b>to get this to work on the remote web server. Again it works on my local machine but not when i upload it to the remote server.

Thanks in advance

The bin folder is located in the root folder of the application, e.g. /bin. If the root folder is at d:\webs\omixad then the bin folder is d:\webs\omixad\bin.

Upload the dll files from the folder to a bin folder on the server located in the web root.

Hi there,
In fact, with the ASP.NET 2.0 you can deploy your web pages with the source code .cs without having to compile it to the assembly and put it in the bin folder. In this case, i would double check if the ASP.NET version 2.0 is used with the application on the remote server.

Does anyone have any samples, or a good vendor that has this product to purchase that will run under IIS? I have searched up and down and would preffer someting simple and

Hi Mike. I don't have a reference for you, but it sounds like a straight-forward kind of application to build. You could use the Membership API to support user authentication easily enough, develop a form that includes text boxes you want for resume input... there are lots of ADO.NET examples out there for storing data in a SQL-compliant database... if you start to build it and run into some specific problems, post the issues.

Holding your scroll position after postback without SmartNavigation

Hey guys and girls. It's been awhile since I have done any asp.net programming and today while trying to remember how to keep my position on the page after a postback I ran across some articles about SmartNavigation that made me reconsider using it. I'm sure several here know what I'm referring to so my question is how do you get around it so that you can keep your scroll position on the page in at least IE and Firefox?

I saw this article today Hold Your (Scroll) Position[^]. Is anyone using this technique?

Thanks for the info,
Richard

Hi there. In 2.0 you can use the MaintainScrollPositionOnPostBack attribute of the @Page declaration:

<%@ Page Language="C#" MaintainScrollPositionOnPostBack="true" %>

ItemDataBound event didn't occur when the form is postbak.

I have a web form with a datagrid. One column is select column, another column is privilege column. I add code in ItemDataBound event. Show privilege column only the user has privilege. Otherwise the text in grid cell will be "". Basically hide the cell. but however, when I click select column to show other form, when I come back from that form, then I notice the privilege column changed. All cells in the column show privilege. I step into the code, I found out the ItemDataBound event didn't get fired when the form postback. The grid get a kind of rebind. How can I prevent it happen?

Hi there,
The ItemDataBound event only gets fired when you call the DataBind method. If you want this event to raise on postback, you need to call the DataBind method again, but remember to set the EnableViewState property to false in order for the post back events to run properly. Another option is to use the ItemCreated event instead which always occurs when the page is visited.
