I used to use ASP 3.0 and I think the concept of this may have changed and I'm overlooking something very simple Can anyone help the 2 pages are below: login.aspx.... -------------------------------------------------- void Page_Load() { welcomeNote.Text = "<center><b>Please enter your Username and Password to login to the GDCLTD Admin System:</b></center>"; } <title>GDCLTD ASP.NET BETA <asp:label id="welcomeNote" runat="server"> http://www.gdcltd.net <asp:table id="loginTable" border="1" width="25%" runat="server"> <asp:tablerow> <asp:tablecell> Username: <asp:textbox id="username" runat="server" size="18"> Password: <asp:textbox id="password" runat="server" size="18"> ------------------------------------------------------------------- checklogin.aspx -------------------------------------------------------------------- <%@ Import Namespace="System.Data" %> <%@ Import Namespace="System.Data.OleDb" %> void Page_Load() { string strConnection = "Provider=Microsoft.Jet.OleDb.4.0;"; strConnection += @"Data Source=C:\gdcltdDotNet\gdcltd.mdb"; string strUsername = Request.Form["username"]; //get username from login.aspx string strPassword = Request.Form["password"]; //get password from login.aspx string strSQL = "SELECT * FROM tbl_users WHERE username = '" + strUsername + "';"; //try and make connection try { OleDbConnection objConn = new OleDbConnection(strConnection); OleDbCommand objCommand = new OleDbCommand(strSQL, objConn); OleDbDataReader objReader = null; objConn.Open(); //open connection to database objReader = objCommand.ExecuteReader(); while (objReader.Read() == true) { if(objReader["username"].ToString() == strUsername) { if(objReader["password"].ToString() == strPassword) // username and password match { Response.Write("Details correct"); } } } objReader.Close(); objConn.Close(); } catch(Exception e) { Response.Write(e.Message); //write error message } } -------------------------------------------------------------------------------------- If anyone knows how this could be done better or used in one page or something, can you let me know as I'm just starting out in asp.net modified 19-Aug-21 21:01pm. Wierd Problem John Pepper20-Sep-02 5:27 John Pepper 20-Sep-02 5:27  Hi, I discovered a wierd asp.net problem yesterday, for some reason I can only view my asp.net pages on msnexplorer. This means that I can't debug or test my pages in IE6, the controls all come up but the code won't work. I tried reinstalling the framework but for some reason this won't work. Any help would be vastly apperciated. Thanks Re: Wierd Problem Paul Watson20-Sep-02 5:47 Paul Watson 20-Sep-02 5:47  akula wrote: the controls all come up but the code won't work How does the code not work? Is it a client side browser error or an error on the server side? Some more detaild would help us to help you BTW I use IE6 and all my ASP.NET stuff works fine. Paul Watson Bluegrass Cape Town, South Africa Re: Wierd Problem akula20-Sep-02 6:09 akula 20-Sep-02 6:09  Sorry about that, For example I just put a text box and a button on a form and write some code that makes the text box display hello. I complied that and attemped to debug it and start it without debuging, the IE window comes up and the textbox and button are there, but when I click the button it fails to change the text boxes text. I then tried to go to that directory by typing in localhost/webapplication1/webform1.aspx, this produced the same effect in IE. However, If I attempt to do that in MSNExplorer, the code works perfectly, and the text box contents change. On my old computer IE6 worked perfectly as well. Re: Wierd Problem akula20-Sep-02 13:06 akula 20-Sep-02 13:06  IE6 won't run the test samples either, it will only show the controls, but MSNExplore will run the samples, I really need it to get fixed so I can debug the app in the IDE.

Megan Forbes22-Sep-02 9:41 Megan Forbes 22-Sep-02 9:41  'replace' is a method of location, which takes the URL you want to load as a parameter. There is loads of this stuff in the Netscape online files (developer.netscape.com) On a possibly interesting note, it can also be put into a javascript function - ie. Your button calls a validation function, which determines which fields have been populated. According to this information you choose to send the user to different URLs (location.replace) instead of either failing the form or submitting it.

It is not 100% accurate though and I don't think there is a 100% accurate way of doing it apart from embedding some Java Applet into the page (which would be overkill.)

In the parent page, I want to pop up a child page at the specified location of the parent page and have a specified width and height. How to use JSP to do it? Cheers, George Re: Pop up a child page at the specified location of parent page. MHeckman22-Sep-02 12:45 MHeckman 22-Sep-02 12:45  George, I the result you want can be achieved by using javascript on the client. Have a look at the window object: showModalDialog and showModelessDialog and using an IFrame in the pop-up child window. (I recommend the IFrame because it allows you to treat the content like a regular web page but the entire child window can be made modal to the parent window... I hope this helps.

I noticed that in java.sun.com, for each type of OS, there are two materials deals with Java to download, they are JRE and JDK. My question is, what is the difference between JRE and JDK? If I just want to Programming with Java, I think I only need to download JDK. Am I correct? Cheers, George Re: What is the difference between JDK and JRE? David Salter19-Sep-02 11:22 David Salter 19-Sep-02 11:22  The JRE is the Java Runtime Environment and the JDK is the Java Development Kit. You would use the JDK to write and run software and you would use the JRE to run it. Dave. Re: What is the difference between JDK and JRE? George Ma19-Sep-02 17:18 George Ma 19-Sep-02 17:18  Thanks, Dave pal! I have got the point. Cheers, George Re: What is the difference between JDK and JRE? HoseaH19-Sep-02 20:51 HoseaH 19-Sep-02 20:51  JDK (Java Development Kit) is what is needed to develop and deploy java application i.e. a kind-of-interpreter/compiler for Java since it contains the compilers and debuggers. Its needed by the Java Developer/programmer. JRE(Java Runtime Environment is to be used by the Java application user and consists of the Java Virtual Machine, the Java platform core classes, and supporting files - hence JRE is neede d to run Java Application Re: What is the difference between JDK and JRE? George Ma20-Sep-02 2:34 George Ma 20-Sep-02 2:34  Thanks, Hoseah pal! I have understood the concept.
