Html in Asp.Net variable causeing errors

I am using this code:

Dim strPopup as String = "<script>alert('hello world');</script>"

The closing script tag is screwing up the vb code. I don't know why..This is a protection to avoid script tags in asp.net code which can break the server-side scripts in ASP.NET (when a </script> is detected). Use this little workaround to solve the problem:

Dim strPopup as String = "<script>alert('hello world');</script"+">"

.
Another solution is to avoid the direct use of <script> tags by using the properties of, for example, the <body> section of the page:


<body onload="alert('hello world');">
...

HTML in a variable

Im using asp on a win2k3 server. I would like to put a lot of html into 1 variable. I get an error when i try to do it my way.


'Here is an example of what I would like to do, kinda.
application="<html>
<head>
<title>Join</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<link href="http://links.10026.com/?link=join.css" rel="stylesheet" type="text/css">
</head>"


'Here is the error.
Microsoft VBScript compilation error '800a0409'Unterminated string constant
/cfcs/join/mail.asp, line 17
application="<html>
------^

I was wondering if anyone could suggest an effective method of doing this.you should replace the double quotes(") by a single quote(') and instead of adding new line for the variable value you can use <br
application="<html><br><head><br><title>Join</title><br><meta http-equiv='Content-Type' content='text/html; charset=iso-8859-1'><br><link href='join.css' rel='stylesheet' type='text/css'><br></head></html>"

Hope this helps

HTML IMG vs ASP:IMAGE performance

I have no need to have server control over an image.
What is the best choice to use HTML img tag or asp:image for best
performance?
thanks,
Goncalo BoleoHTML controls provide slightly better performance than Web Controls, so go
with the img tag.

If there's no need to have a server control, then just use a <img> tag (prim
arily
for simplicity, even though it is faster but it's negligible). If you are
using a server control there's essentially no difference between the HtmlCon
trols
and the WebContorls.

HTML IMG SRC

Hello,
I am dealing with a lot of published pages on a particular website.
(web-editor/publish/archive) It is easier for me to remove all of the
"../../imgageDir/image001.jpg" references and replace then with
http://www.aWebsite.com/imageDir/image001.jpg...
Will this slow down my website or the rendering of the html pages. It is
all happening on the same website (no external images)
ie,
<html><body>
<img src="http://pics.10026.com/?src=../../imageDir/image001.jpg">
<img src="http://pics.10026.com/?src=../../imageDir/image002.jpg">
</body></html>
---
OR
---
<html><body>
<img src="http://pics.10026.com/?src=http://www.aWebsite.com/imageDir/image001.jpg">
<img src="http://pics.10026.com/?src=http://www.aWebsite.com/imageDir/image002.jpg">
</body></html>
which one is faster?
THanks,
PaulNiether is faster. Both are the same.

html image percentage issue

I am unable display an image by percent. No matter what method I try,
I receive the following error.

Input string was not in the correct format.

No matter what method I use, I cannot get this to show up in a percent
format. What am I missing here.

currentStatusImage.Src = "../builds/images/green.gif"
currentStatusImage.Width = "60%"

Thanks.currentStatusImage.Width is expecting a Unit, not a string, so you need to
do a Unit.Parse("60%") or a Unit.Percentage(60).

Bill Priess

Using M2, Opera's revolutionary e-mail client: http://www.opera.com/m2/
I get an error stating that unit cannot convert to an integer, on both of
those attempts.

From the documentation:

HtmlImage.Width Property

Gets or sets the width of the image.

Public Property Width As Integer

Property Value

The width of the image.

It does, the sdk also states that you can also set the value as a
percentage. The problem is that it doesn't give an example or any
detail to that.

"By default, the Width property is expressed in pixels, but it can
also be expressed as a percentage of the window size." - straight from
the windows sdk, and that's all it has to say about it. But how??

It seems you've found a documentation error.

An integer is an integer, not a Unit. You can't use percentage in an
HtmlImage.

Any ideas on how to get around this. In addition to this being an issue,
when I attempt to do the following ( going back to my asp classic way of
thinking ) :

<img border="0" id="currentStatusImage" src="http://pics.10026.com/?src=<% = srcInfo %> width="<% =
widthInfo %>%" height="6" runat="server"
I still get the integer error. I'd rather not make this a static image but,
the list of ideas grows smaller. Thanks.

You're still getting the error because you've still got the control marked
as runat="server", which means it's an HtmlImage, which means that the Width
property is an integer.

Do you really need the image to be a server control?

And why not use style="WIDTH:100%" :

currentStatusImage.Style["WIDTH"] = "100%"
