I was wondering if it would be possible to login to a webpage using a random username and password from a txt file.
For example the txt file would be like this:-
username1 password1
username2 password2
username3 password3
username4 password4
username5 password5
How would I do something like that?
I have a form with a Tab Control that has 18 pages. When I click on a tab it opens the page and select a textbox on that page (txtTextbox1. Select() ). This works for the first 8 pages but not for the remaining 10 pages. Although on these pages I can mouse click on the textbox, enter info, save then click my Add button that clears the textboxes and has the code (txtTextbox1. Select() ). The textbox is selected just fine. The code for all my pages is the same except for the tab name and the control names. The tab key will move the selection to the next textbox in order on all pages and the Enter key is coded to do the same. The first 8 pages have a total of 256 labels, buttons, list boxes, textboxes and checkboxes on them.

I want to access a page variable from a user control placed on that page. All the solutions work in C# via casting to the page class. The problem is that this doesn't work in VB. The page class is not selectable from the Intellisense dialog. Manual typing results in the error type not defined. It is strange that C# can do this without a problem. What is the proper solution for this in VB? I had other cases where I needed to access a control on the main page. C# again uses a cast to the page class to access the control. This doesn't work in VB again. So how can I access the page class from a user control in generell?

View 2 RepliesLet's say we have a value coming in through the URL of a page. Example: www.test.com/page.aspx?&Key=Val. Val is retrievable through Request.Querystring("Key").Is there an accepted best practice for assigning a QueryString Value to a parameter of a SqlDataSource defined on an ASPX page?
Options that I know of: Do not include parameters in the ASPX file. Add them directly through the codebehind -- and assign Param.DefaultValue upon adding. Set Param.DefaultValue in the page load (Codeblock 2)
Both of these use DefaultValue, a property that clearly was not intended to be used in this manner. Do the ASP.NET overlords have a recommended method in mind for achieving this common task?

Jst recently i came across the select() method of data table and felli n love with it instantaneously.
Basically I want query the data table on a date field, unfortunately the format of the date string returned from y database in to data-table and the date string i'm passing as inputs are different.
How can i make sure that the data is compared irrespective of the formats ? Can I use something like SqlParameters whoes data type is date for comparison ??
this is what i'm tying :
dim dat as date = "#1/3/2009#"
dt.select("StzDate ='" & dat "'")
entry in datateable dt : StzDate : 3/1/2009 12:00:000
Am I do'in something wrong ??
Also, can anyone redirect me to some site where I can learn a bit more about passing parameters to the select statement,etc...
It is simply a "Y" in the road. If they are Company A, then I want to send the username and password over to that website and log them in as if they typed it in there. If they are Company B, then the same thing but with a different website. I do not know the term for this, so the google results are not very pretty.I can not do this with a query string (not that I'd want to anyway) as I do not want the username/pw to be visible.Here is the other weird thing. This can be done via a simple HTML <FORM> and Submit button as I have tested it. But I want to do it all in VB.NET code. How is it that it is possible with some simple HTML but not possible in VB.NET? I guess it could be a security thing, right? What do the good guys like us do when we legitimately just want our employees to go to one login page, enter their username/pw, and then (based on their username) send them to either pageA.aspx or PageB.aspx which receives their username/pw that they only entered once before on the first page?
