This code is the minimal. Here it validates the user name and password are admin. In case both the values are admin it allows login. Else it returns an error message - error!\n\nThe only thing that may be confusing for you over here may be the session concept. \n\nThis code has no databse connectivity. Incase you are planning for a database based project use a MS Access connectivity. Its easy.\n\nLet me explain this code\n\n<% IF Request.form="" THEN %> \n<html> <body> In order to access this pages fill the form below:<BR> \n'THIS IS TO POST DATA FROM THE PAGE\n<form method="post" action="index.asp"> \nUsername: <input type="text" name="username" size="20"><BR> \nPassword: <input type="password" name="password" size="15"><BR> \n<input type="Submit" value="Submit"> \n</form> </body> </html> \n<% ELSE %> \n'IF USERNAME AND PASSWORD NOT admin RETURN an ERROR\n<% IF Request.form("username")="admi... AND Request.form("password")="admi... THEN %> \n<% Session("permission")="YES" \nSession("username")="admin" \n%> \n<html> <body> \n'THEN YOU CAN VIEW PAGE1 &  PAGE2\nHi <% =Session("username") %>, you can view: <BR> \n<A HREF="page1.asp">Page 1</A><BR> \n<A HREF="page2.asp">Page 2</A> \n</body> </html> \n<% ELSE %> Error! <% END IF %><% END IF %>\n\nYou can mail me to technoblitzs@yahoo.com incase you have any clarification or want to connect to  a database.

Go for Black Book for VB.\nComplete Reference for C++ is good.\nC++, Java and .Net are valued.

It appears to be a string function, one that looks at the character at the position indicateded.  Don't quote me on VB syntax, but something like this \n\nvar string mystring = "Hello";\nmystring.IndexOf('e');  <-- this would give you a value of "1" (one), assuming the indexing starts at zero.

This code is from 4guysfromrolla.com.  There are other ways to accomplish this as well.  Hope this helps!\n\n\n<script language="vb" runat="server">\n  ...\n   \n  Sub dgPopularFAQs_ItemDataBound(sender as Object, e as DataGridItemEventArgs)\n    ' First, make sure we're NOT dealing with a Header or Footer row\n    If e.Item.ItemType <> ListItemType.Header AND _\n         e.Item.ItemType <> ListItemType.Footer then\n      'Now, reference the LinkButton control that the Delete ButtonColumn \n      'has been rendered to\n      Dim deleteButton as LinkButton = e.Item.Cells(0).Controls(0)\n\n      'We can now add the onclick event handler\n      deleteButton.Attributes("onclick") = "javascript:return " & _\n                 "confirm('Are you sure you want to delete FAQ #" & _\n                 DataBinder.Eval(e.Item.DataItem, "FAQID") & "?')"    \n    End If\n  End Sub\n</script>\n\n<form runat="server">\n  <asp:datagrid id="dgPopularFAQs" runat="server"\n      ...\n      OnItemDataBound="dgPopularFAQs_ItemDataBound">\n\n      ...\n  </asp:datagrid>\n</form>

generally, validation limits what can go in a field.  \n\nfor example, if the field was "email address," you would want to write a validation algorithm that confirmed someone entered a properly formatted email address (ie: doofus@nowhere.com)\n\nas a programmer, YOU have to decide whether a field should be validated.  as you develop your project, ask yourself "is the user smart enough where i don't have to code for it?"  if you're already asking the question, the answer is usually "no."

I don't use vb.net myself (C# I use).\n\nIf you want to keep the 0's in the front though, it has to be a string, not an integer.\n\nYou convert it over to integer, add the next number, then cast it back to string, and pad the length to the desired number of 0's\n\nPseudo code:\n\nLicenseNoNum = CastToInt(LicenseNostr)\nLicenseNoNum = LicenseNoNum + 1\nLicenseNoStr = CastToStr(LicenseNoNum)\nWhile LicenseNoStr(Length) < 8\nLicenseNoStr = '0' + LicenseNoStr.\n\nYou could also just store it as an integer, and perform the cast for printing, which might be all you were looking for.

I have used VB for years and as far as I know, it doesnt have dynamic arrays. VB was not designed to be used like that so it probably doesnt have a syntax for it.

Go in the Data menu, then select Validation.\n\nYou can select "List" in the drop-down menu and enter either a cell range or custom values in this format: "A;B;C" (without the quotes)\n\nGood luck!

Here's a pretty good one I wrote:\n\nhttp://www.planetsourcecode.com/vb/scripts/ShowCode.asp?txtCodeId=58476&lngWId=1\n\nYou'll need Visual Basic to compile it or you can e-mail me and I'll send it to you...
