Help! error: Object required "this"

17-Feb-03 19:54

1. Your code snippet on mouseover is very helpful. I will try it now.
2. Just check my browser setting. I use Internet Explorer 6.0 and under:
Options
>Security
>Security Setting
>Microsoft VM
>Java Permissions
>Low Safety

So, I doubt that the problem is with my browser setting.

My aspx code (Ask me for a complete file if you wish I can send it to you):

<table id="tblNavMenu" width="220" align="left" runat="server">
<tr onmousedown="Login()" id="rwLogin" onmouseover="document.getElementByID(rwLogin).bgColor='LightSteelBlue'" style="CURSOR: hand" onmouseout="document.getElementByID(rwLogin).bgColor='Ivory'">
<td align="middle">Login
</td>
</tr>
<tr onmousedown="Logout()" id="rwLogout" onmouseover="this.bgColor='LightSteelBlue'" style="CURSOR: hand" onmouseout="this.bgColor='Ivory'">
<td align="middle">Logout
</td>
</tr>
<tr onmousedown="NewReg()" id="rwRegister" onmouseover="this.bgColor='LightSteelBlue'" style="CURSOR: hand" onmouseout="this.bgColor='Ivory'">
<td align="middle">Register
</td>
</tr>
<tr onmousedown="UnReg()" id="rwUnReg" onmouseover="this.bgColor='LightSteelBlue'" style="CURSOR: hand" onmouseout="this.bgColor='Ivory'">
<td align="middle">UnRegister User
Account
</td>
</tr>
<tr onmousedown="ChangeProfile()" id="rwChangeProfile" onmouseover="this.bgColor='LightSteelBlue'" style="CURSOR: hand" onmouseout="this.bgColor='Ivory'">
<td align="middle">Change Personal
Profile
</td>
</tr>
<tr onmousedown="TransferMasterForum()" id="rwForum" onmouseover="this.bgColor='LightSteelBlue'" style="CURSOR: hand" onmouseout="this.bgColor='Ivory'">
<td align="middle">Forums
</td>
</tr>
<tr onmousedown="GoHome()" id="rwHome" onmouseover="this.bgColor='LightSteelBlue'" style="CURSOR: hand" onmouseout="this.bgColor='Ivory'">
<td align="middle">Home
</td>
</tr>
</table>

That's it. Note that I did things differently in row 1 (in comparison with the rest of the grid. I use the "document" object - but none worked anyway.)

Thanks.

Help! error: Object required "this".

I just did testing on your code in regards to onmouseover. I sufferred from the same problem working with DataGrid's "item" as data row <tr> on my HTML table.

Following is a few things I tried, I keep getting:

error: Object required: 'this'

I have tried many things and I really cant solve this. Help!

CASE 1: HTML table row

<tr onmousedown="Login()" id="rwLogin" onmouseover="document.getElementByID(rwLogin).style.backgroundColor='LightSteelBlue'" style="CURSOR: hand" onmouseout="document.getElementByID(rwLogin).style.backgroundColor='Ivory'">
<td align="middle">Login
</td>
</tr>

CASE 2: HTML table row

<tr onmousedown="Logout()" id="rwLogout" onmouseover="this.style.backgroundColor='LightSteelBlue'" style="CURSOR: hand" onmouseout="this.style.backgroundColor='Ivory'">
<td align="middle">Logout
</td>
</tr>

CASE 3: HTML table row

<tr onmousedown="NewReg()" id="rwRegister" onmouseover="this.bgColor='LightSteelBlue'" style="CURSOR: hand" onmouseout="this.bgColor='Ivory'">
<td align="middle">Register
</td>
</tr>

CASE 4: DataGrid Item

//Set mouseover and mouseout attributes:
foreach( DataGridItem item in this.dgForum.Items)
{
//Mouseout:
if (item.ItemType==ListItemType.Item)
{
item.Attributes.Add("OnMouseOut", "this.style.backgroundColor='Snow'");
}
else
{
item.Attributes.Add("OnMouseOut", "this.style.backgroundColor='GhostWhite'");
}

//Mouseover:
item.Attributes.Add("OnMouseOver", "this.style.backgroundColor='Red'");

}

norm,

If you don't mind, email me your .aspx page and I will take a look. Or if this is on an external site, I can try to hit it and see if I get the same result. Were you able to properly see the code in the Article link Demo I posted earlier? Also, send me the table structure and two or three lines of data so that I can test it in my test database.

Adding video to the Web page??

17-Feb-03 20:43

Thanks for the feedback, i got some many junk mail from spammers aronud the world that i missed your reply.

I've got QUESTION 1 and QUESTION 3. The remaining problem is QUESTION 2.

//Event handler for DataGrid's OnItemDataBound: When user mouseover/mouseout a row.
protected void ItemDataBound(Object sender, DataGridItemEventArgs e)
{
if (e.Item.ItemType==ListItemType.Item || e.Item.ItemType==ListItemType.AlternatingItem)
{
//BUG
//e.Item.Attributes.Add("onmouseover", "this.style.backgroundColor='LightSteelBlue'");
//e.Item.Attributes.Add("onmouseout", "this.style.backgroundColor='Ivory'");
}
}

But the browser keeps complaining about "this" object. Error message is:
Error: Object required: "this"

I was advised to check browser setting for Java VM - which I set to LOW - the problem persists and I doubt that Java VM setting is the problem. I have not been able to solve this problem.

I am using it like this.

<embed src="ABC.AVI" height="250" width="33%" controller="true" autoplay="false" playeveryframe="false" pluginspage="oops.html" loop="false" />

1. I want to disable the right-click on the video. How to do that?
Reason : So that people won't use Full Screeen or Zoom 200%

2. How to stop the audio stream via this tag? (Embed)
I just want to give the video not audio. (mute audio)

If I had a suggestion for an addition to the HTML standard how would I go about proposing it?

Do I contact someone directly at the W3C?

Problem connecting to Access database

Chris LaQuerre13-Feb-03 3:12

I am getting a Server 500 error whenever I try to connect to an Access DB.

I've used the code below in an Intranet test environment and it works fine. However, when I moved this over to our external Intranet site, I get the server error. (This is the first time that I've tried to connect to a DB on this server. I can run regular ASP scripts fine). Does anyone have any clues about why this would happen? Does anything need to be set up on this server to allow it to connect to an Access DB? The web server that we are trying to get this running on is Microsoft-IIS/5.0 on Windows 2000.

Here is the code that I am using to connect:

<br />
<% @Language = VBScript %><br />
<br />
<%<br />
	Dim MyConn, SQL, RS, id<br />
	Set MyConn=Server.CreateObject("ADODB.Connection")<br />
	MyConn.Open "DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=" & Server.MapPath("test.mdb")<br />
	SQL = "SELECT * From TEST;"<br />
	Set RS = MyConn.Execute(SQL)<br />
%><br />
<br />
<html><br />
<body><br />
<table width="100%"><br />
	<!-- displays news item info from database --><br />
	<% <br />
		While Not RS.EOF <br />
	%><br />
 	<tr><br />
		<td valign="top"><%= RS("DATA") %></td><br />
	</tr><br />
<br />
	<% <br />
		RS.MoveNext<br />
		Wend<br />
	%><br />
</table><br />
<br />
<%<br />
	RS.Close<br />
	MyConn.Close<br />
	Set RS = Nothing<br />
	Set MyConn = Nothing<br />
%><br />
<br />
</body><br />

u mean besides the driver ur telling it to use and MDAC for ADO? I don't think so.

does that help?

Try going into your browser configuration and turning off the 'freindly errors' option. You should get more back than a simple '500 error' then.

Damn, that one...

I have seen this before, and unfortunately have never been able to nail it down to exactly what causes it.

I noticed that it seemed to happen more frequently if I sent up a new copy of my database after I had edited locally.

A few things that I have done to get past it:

- Moved from a DSNless connection to using a DSN

- Moved from Access to SQL Smile | :)

- Stopped making additions to my database locally and sending up a new DB. I instead performed all my maintenance (record additions and deletions) via ASP pages.

Sorry I can’t help more. If you do a simple search on Google for that number you will see that there are many others out there with the same problem.

simple question on SQL CURSOR

Hi Chris,
I know what is the solution of this problem.

Your code is absolutely right...no errors in your code...
I suggest that you can host your web pages on "http://www.brinkster.com" and then check it because some "Free Web Space" provider don't give the permission of using database. You simple make an account on brinkster and then check it out. For more information about Web Development Contact me (zeeshan_kyo@hotmail.com) also you can see a live version of my brinkster account at "http://www24.brinkster.com/zeeshan123/zeeguest_view.asp" I think it's enough....

Hi, I have a table with NO row index.

But I need to loop through all rows in the table and retrieve the "first_name" (second column) one at a time from WITHIN A STORED PROCEDURE (so, not asking about ADO and stuff here.)

So, roughly, the pseudo code will look like this:

DECLARE my_cursor CURSOR
... then what...
WHILE !my_cursor.EOF

fname=my_cursor("first_name")
FETCH NEXT my_curosr

END WHILE

Can someone translate this into SQL statement please?

PRINT '@login: ' + @login
FETCH NEXT FROM temp_cursor INTO @login

CLOSE temp_cursor

Problem. I've run into problem declaring my cursor: table name is dynamic (@temp_table_name). Help! Code as follows:

DECLARE temp_cursor CURSOR FOR SELECT strToken FROM @temp_table_name
OPEN temp_cursor
FETCH NEXT FROM temp_cursor INTO @token
WHILE @@FETCH_STATUS <> -1
BEGIN
PRINT 'CURSOR TOKEN: ' + @token
FETCH NEXT FROM temp_cursor INTO @token
END
CLOSE temp_cursor
DEALLOCATE temp_cursor

norm,

From what I can tell, you really do not need a cursor. Will the following work? I am assuming you are using SQL Server, if not, what database?

SELECT @login = login FROM passwords

This sets the @login variable = login fom the table. The risk you run is if your query returns more than one value.

Let me know if this doesn't solve your problem.
