Flash and ASP Guestbook

Classic guest book made with ASP and Flash

I have created this script using Flash and ASP.Data is saved in access database and retrieved through ASP and displayed in Flash movie in HTML format. PHP version of the same Guestbook is available under PHP section.

Steps

Start a new flash movie. Insert a new Dynamic text box and give it name txtmain and don't forget to check the HTML option. Insert a dynamic text fields status which will be used for displaying messages. Insert a new layer, name it action and place following code in action window.

lowlimit = number(1);
highlimit = number(10);
loadVariablesNum ("asguest.asp", 0,"post");
stop();

lowlimit and highlimit are the flash variables that would be send to PHP script. First time data range from record 1 to record 10 will be displayed in HTML enabled text box.

Insert two new button instances for up and down scrolling

For Up Button
on (release) {
txtmain.scroll--;
}

For Down Button
on (release) {
txtmain.scroll++;
}

Above code is self-explanatory.

I am not giving details for SCROLLING the movie. I will add a new tutorial in the flash section.

Add two button instances for Next 10 and previous 10 records and add the following code in action window.

Code for next Button
on (release) {
lowlimit = Number(lowlimit)+Number(10);
highlimit = Number(highlimit)+Number(10);
txtmain = "Processing Entries from "+lowlimit+" to "+highlimit+" Please wait ::: ";
loadVariablesNum ("asguest.asp", 0,"post");
}
Code for Previous Button
on (release) {
if (txtll == "1") {
txtmain = ":::: Nothing before Zero ::::";
}else {
lowlimit = Number(lowlimit) - Number(10);
highlimit = Number(highlimit) - Number(10);
txtmain = "Processing Entries "+lowlimit+" to "+highlimit+" Please wait for a while :::::: ";
loadVariablesNum ("asguest.asp", 0,"post");
}
}
Add three dynamic text fields to the movie for Total entries(totalentries),Low Limit (txtll) and High Limit (txthl) respectively.

Now Insert a new movie instance. Place four dynamic text boxes for name(textname) , email (txtemail) , website (txtwebsite) and comments (txtcomments). Add two buttons for Submit and Reset.

Code for Submit Button

on (release) {
if (txtname == "") {
_root.txtmessage = "Name information missing.";
} else if (txtemail == "") {
_root.txtmessage = "Email missing.";
} else if (txtcomments == "") {
_root.txtmessage = "Comments missing.";
} else if (txtwebsite == "") {
_root.txtmessage = "Enter the URL to your website";
} else {
submit1 = "Y";
highlimit = 10;
lowlimit = 0;
_root.txtmain = "wait :::: Posting New Entry ::: ";
loadVariablesNum ("/asguest.asp", 0, "post");
_root.txtmessage = "Comments posted";
txtname1 = txtname;
gotoAndStop (2);
}
}

Code for reset button

on (release) {
txtname = "";
txtemail = "";
txtWebsite = "http://";
txtcomments = "";
}
