Visual basic simple Case statement question
karljv replied to karljv's topic in Other Programming Languages
Okei, so i understood it completely wrong, instead of running only one line of code, it runs my entire timer1_tick code line. Why does it not select a case on every tick? Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick Select Case x Case x = 0 TubaTemp = ((TubaTemp) + (RadikaTemp / (TubaTemp * 3))) + SoojusKadu If SwitchCold > TubaTemp Then RadikaTemp = 40 End If If SwitchWarm < TubaTemp Then RadikaTemp = 30 End If Rad.Enabled = False TTemp.Text = TubaTemp.ToString("N2") RTemp.Text = RadikaTemp Case x = 1 TubaTemp = ((TubaTemp) + (RadikaTemp / (TubaTemp * 3))) + SoojusKadu Rad.Enabled = True RadikaTemp = CDec(Rad.Text) TTemp.Text = TubaTemp.ToString("N2") RTemp.Text = RadikaTemp End Select End Sub taking into account that (Dim x as integer) and on Form load x=0 -
Hello I have a simple question. How to have the case statement execute more than one command? My code Case x = 1 TubaTemp = ((TubaTemp) + (RadikaTemp / (TubaTemp * 3))) + SoojusKadu Rad.Enabled = True RadikaTemp = CDec(Rad.Text) TTemp.Text = TubaTemp.ToString("N2") RTemp.Text = RadikaTemp So it seems tu execute only the first mathematical thingy. All the rest ( Rad.enabled = true and downward) do not execute. Thanks

So I am new to all this coding and I am making a small website, which has to have a login and something is not working properly. My login user/pass processing code looks like this <?php $host = 'xxxx'; // Host name Normally 'LocalHost' $user = 'xxxx'; // MySQL login username $pass = 'xxxx'; // MySQL login password $database = 'members'; // Database name $table = 'members'; // Members name $username = $_POST["username"]; $password = $_POST["password"]; $connection = mysql_connect("xxxx", "$user", "$pass"); if (!$connection) { die("Database connection failed: " . mysql_error()); } else { echo "Everything is fine!<br />"; } mysql_select_db("xxxx",$connection) or die(mysql_error()); $result = mysql_query("SELECT * FROM members WHERE usr='$username' and pass='$password'",$connection) or die(mysql_error()); $count=mysql_num_rows($result); if($count==1){ session_start(); session_register("myusername"); session_register("mypassword"); header("location:Login_Success.php"); } else { echo "Wrong Username or Password"; } ?> So it all continues well and transfers me to Login_Success.php, where the code looks like this <? if(!session_is_registered(myusername)){ header("location:MainPage.htm"); } ?> <html> -----my html code here, which makes no difference---- The problem is that it sends me to MainPage.htm and I can't really figure out why. As ive said im new to all of this. I figured that the session did not stay logged in, when it changed pages for some odd reason? THANK YOU!
