Writing VBScript in a "classic" ASP page...

I have several similar instances of the following code in a file called mypage.asp

<a href="mypage.asp?myAction=action1&myValue=1">Action1</a>

At the top of the same file, I have the following code:

Dim sAction: sAction = request.QueryString("myAction")
Dim sValue:  sValue  = request.QueryString("myValue")

' CHECK QUERYSTRING HERE

select case sAction
    case "action1"
        DoSomethingWith1(sValue)
    case "action2"
        DoSomethingWith2(sValue)
    case "action3"
        DoSomethingWith3(sValue)
    case "action4"
        DoSomethingWith4(sValue)
end select

Everything looks normal, right? (BTW, I typed this from memory so pardon any minor typos.)

Bizarre - Part 1

The first two "actions" are processed as you would expect. When I check the querystring at the indicated position (I throw up an alert box with the values in it), I see the values I expect. When it processes either of the 2nd two post-backs, the query string is empty.

Bizarre - Part 2

If I leave the select statement alone, but change the NAME of either querystring parameter, I get the expected querystring parameters

Does anyone have any idea as to what I might have done wrong?

Are you sure that these functions don't change the values of QueryString collection?
Can you post a complete sample so I can run it locally and check it?

I'm not sure you could duplicate it on a simpler page. I haven't tried it yet myself, but I'm going to when I get to work today.

How to launch project in IE (keeps coming up in firefox)

14-May-07 4:16

Okay - here's the page cut down to almost bare minimums

<%@ LANGUAGE="VBSCRIPT" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title></title>
    <meta http-equiv="Expires" content="0" />
</head>
<body>

<%
'-------------------------------------------------------------
sub Alert(sMsg)
    Response.Write("<script type='text/javascript' language='javascript'>" _ 
                   & "alert('" & sMsg & "');</script>")
end sub

'-------------------------------------------------------------
function DoSomething(sAction)
    DoSomething = "Something was done for " & sAction & "."
end function

'-------------------------------------------------------------
'-------------------------------------------------------------
Dim myAction:       myAction       = request.QueryString("myAction")
Dim sRoomToProcess: sRoomToProcess = request.QueryString("roomid")
Dim sSomethingDone: sSomethingDone = ""
Dim bNeedRedirect:  bNeedRedirect  = false

Alert myAction & "\n" & sRoomToProcess

select case myAction
    case "moveUp"
        sSomethingDone = DoSomething(myAction)
        bNeedRedirect = true
    case "moveDown"
        sSomethingDone = DoSomething(myAction)
        bNeedRedirect = true
    case "addRoom"
        sSomethingDone = DoSomething(myAction)
        bNeedRedirect = true
    case "deleteRoom"
        sSomethingDone = DoSomething(myAction)
        bNeedRedirect = true
    case "editRoom"
        sSomethingDone = DoSomething(myAction)
    case else
        sSomethingDone = "Nothing was done (no parameters found)."
end select

if bNeedRedirect then
    Response.Redirect("erBoard_roommgr.asp")
end if
%>
<a href="erBoard_roommgr.asp?myAction=addRoom&roomid=Room 1">Add</a><br />
<a href="erBoard_roommgr.asp?myAction=deleteRoom&roomid=Room 2">Delete</a><br />
<a href="erBoard_roommgr.asp?myAction=editRoom&roomid=Room 3">Edit</a><br />
<a href="erBoard_roommgr.asp?myAction=moveUp&roomid=Room 4">Up</a><br />
<a href="erBoard_roommgr.asp?myAction=moveDown&roomid=Room 5">Down</a><br />
<br />
<br />
<p>
<%=sSomethingDone%>
</p>

</body>
</html>

The problem appears to be that it's processing the Response.Redirect line BEFORE it gets the parameters from the querystring. Everything except the "EDIT" link causes a redirect (for purposes of example).

My desire is to actually clear the querystring after retrieving the values to avoid adverse effects caused by the user refreshing the page. I'd have no problem with eliminating the use of Redirect if there's a way to do so.

Hello,

I have firefox installed and I usually use it as my primary browser. However, I want to test my web application in IE. When I run the application it comes up in Firefox. If I open IE and browse to the default.aspx file and try to open it, IE refuses to open it (no error message or anything. IE just minimizes. When I bring it back up, it's still showing the page it was showing before I tried to open my default.aspx page).

I'm new to web development. Help on this will be greatly appreciated!

Thanks!

Ian

OK, so I'm an idiot. Obviously I can't open an aspx file directly as the server has to "serve" it up. So I go ahead and start the project in Firefox, then paste the url into IE, thereby requesting the page from IIS (does that sound right? Please correct me if I'm being a moron here!)

Still, how do hit F5 and launch the project in IE instead of Firefox?

Thanks!

Ian

Self-realization is a wonderful thing. Acknowledging that you have a problem is the first step towards fixing it.

You have to start IE and browse to the page - the URL is necessary so that it can load the appropriate css/js/php script files.

My advice is once you type in the url and successfully get the page to display in IE, bookmark it so you don't have to type it in again. (I only say this because you are a self-proclaimed idiot and I can't safely assume that you'd think of bookmarking it.) Smile | :)

How to highlight the row.....

12-May-07 1:18

I found this on google[^]

I don't know if it will work for you, and if it doesn't, try using google to find something more appropriate.

How can you call yourself a programmer if you're too lazy to do look stuff up on your own?

Calendar enhancement ?

Cody_2111-May-07 7:37

11-May-07 7:37

So, I've searched and searched this group for a Calendar interface for my site. There are certainly a lot of different implementations of the concept. However what I'm looking for is a Calendar that provides a bit more functionality ... and not being a "code jockey", I can't figure out how to modify the Samples here to get what I need. Which is:

1. A normal ASP.NET or VB Calendar that comes up with dates "pre filled" with an Item on a specific date(s)
(e.g., 7 PM - Concert in SF )

2. When I click on that DATE/item on the Calendar, a POP-UP should come up that displays a bit more details
(e.g., 7-11Pm Concert in the Park. info: www.cityconcert.sf/event )

3. The URL referenced in that popup Item should actually allow for a launcn in a separate browser window to that Event detail.

Does anyone know of a Calendar-like ASP.NET (or VB) function that would do this?

Thanks so much ... a very cool site >!!!

BUTTON OVER IMAGE IN ASP.NET?

hifiger200411-May-07 6:38

11-May-07 6:38

Hi Guys,

I wanted to put my 5 buttons over the image. I am using ASP.Net/AJAX. Is there a way in asp.net to do it without using java scripting?

Thanks in advance Guys.

You can set the image as the background of whatever page element is containing the buttons, eg div or table cell...

<style>
...
#imagediv { background-image: #url(myimage.gif) ; }
...
</style>

<div id="imagediv">
... (buttons here) ...
</div>

For fine tuning do some CSS research!

cheers

please try to click this link http://cvd.harnesstheweb.com

You will see there 6 buttons, and I want that button to be put inside the gray bar, which is part of the image. But it can't be done.

I hope you can help me with this Smile | :)

Here is a test page for you, with the code culled from your page - but put the main image in the same folder (or alter the code here) to try it out.
There are "better" ways (ie making better use of the CSS and not having it inline etc), but this works and shows the principle...)
