Um, after looking at it again I did notice the regex for the comments is commented out! Blush | :O

Maybe that's why it's not being pulled?

Thats just a typo...sorry...I forgot about that...

The comments don't exist in the actual source code...

The regex to strip JScript works great, so I figured i'd try and use the same syntax for comments...however what actually happens...i think is it finds the first comment

...Some Body HTML


I'm very very new to regex, so I know nothing about whats going on...basically I just understand the concept...

Is there a repeat or counter character that shouldn't be there...???

Any ideas...?

Thanx in advance..

OIC, try these expressions then...

// Strip SCRIPT tags from source
$buffer = eregi_replace("(<script[^>]*</script>)", "", $buffer);
// Strip COMMENTS from source
$buffer = eregi_replace("(<!--[^>]*-->)", "", $buffer);

Brackets will match a sequence of characters, parenthesis will group characters, and nothing will match explicitly and can be considered as one big ol' group. I made the change to the script tag one too, because after realizing the issue I noticed it also had the same problem.

I'm not new to regex, and the complicated ones can still look like Chinese to me. Smile | :)

AFAIK the script removal code I used works fine...although I only tested it with ONE script tag present...I dunno if it works with 2 or more so it's a good thing you made me think about it...I'd better test it...

I'll definetly have to try yer version of the regex for stripping comments though...cuz i'm starting to loose my mind here...

Thanx alot...

I am having problems finding out how to convert a time from a client's local time zone to GMT/UTC.

It seems the classes I should use would be in the .NET SDK for either System.TimeZone or System.Datetime. However, the .NET Framework SDK's System.TimeZone object does not have a public constructor (and is abstract) and the System.DateTime only creates its CurrentLocalTime according to the server the code is running on.

So, how do I create and specify another timezone? Most of the examples I have found either use JavaScript to display the value in the client's system time or use the standard offset for the client's timezone (which usually does not take into account Daylight Standard Time and the varying dates that the timezone switches to Daylight Time).

Any help is greatly appreciated. Thanks!

This should hopefully help:
Formatting Date and Time for a Specific Culture

There are 3 different sub-topics in this document. The 2nd is probably what you need.

Chris

Chris,

Thank you very much for your response. The section doesn't really tell me how to solve my problem, but actually re-enforces it.

A clip from section 2:

"Methods and properties in the DateTime structure always use the local time zone for calculations and comparisons... You can also choose to format a DateTime for a specific culture."

To elaborate, these classes only allow me to create a DateTime or TimeZone class based on the local time (of the system executing the code, i.e. webserver). Instead, I need to create a DateTime or TimeZone based on a parameter, representing the timezone of the site user's system.

Any other ideas?

Thanks again,
Chris

I found this code at msdn site explaining how to make a master/detail view:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnwebteam/html/webteam02052002.asp

The code is listed below.

musicLibrary.xml
<Artists>
<Artist name="The Chipmunks">
<CD id="4550" name="Eponymous" image="Eponymous.jpg" />
<CD id="4557" name="Hibernation" image="Hibernation.jpg" />
<CD id="4577" name="Going Nuts" image="GoingNuts.jpg" />
</Artist>
<Artist name="The Dogs">
<CD id="4640" name="Full Moon" image="FullMoon.jpg" />
<CD id="4637" name="Old Shoes" image="OldShoes.jpg" />
<CD id="4664" name="My House" image="MyHouse.jpg" />
</Artist>
</Artists>

music.aspx
<%@ Page Language="VB" %>
<%@ Import Namespace="System.Data" %>

<html>
<script language="VB" runat="server">
Dim DS As Dataset = New DataSet

Sub Page_Load(Src As Object, E As EventArgs)

DS.ReadXml(Server.MapPath("musicLibrary.xml"))

Dim CSource As DataView
CSource = DS.Tables("Artist").defaultView
MusicList.DataSource = CSource

'a little code to help display what table relations exist
RelationsGrid.DataSource=DS.Relations

DataBind()

End Sub
</script>

<body>

<ASP:Repeater id="MusicList" runat="server">
<ItemTemplate name="ArtistTemplate">
 <%# Container.DataItem("name") %> 

<ASP:Repeater id="CDList" runat=server
datasource='<%# Container.DataItem.CreateChildView("Artist_CD")%>'>
<ItemTemplate name="CDTemplate">
<img src="<%# Container.DataItem("image") %>"align="absmiddle"/>
<%# Container.DataItem("name") %> 
</ItemTemplate>
</ASP:Repeater>

</ItemTemplate>

</ASP:Repeater>

 
<ASP:DataGrid id="RelationsGrid" runat="server"
Width="300"
BackColor="#ccccff"
BorderColor="black"
ShowFooter="false"
CellPadding=3
CellSpacing="0"
Font-Name="Verdana"
Font-Size="8pt"
HeaderStyle-BackColor="#aaaadd"
MaintainState="false"
/>

</body>
</html>

My problem is that it uses an xml file as a datasource.
Where i want to use two related tables from a database, but i can't seem to figure out how to do that.

I have created a dataset containing the two tables, I have also created a datarelation between the two tables.
I am able to write out the master table if i remove the nested repeater control.

If anyone is able to solve this problem i think a lot of people would be grateful. as i've seen questions
about this master detail thing around the net.

New (relatively) to .Net Confused | :confused:

, and I've got a quick question:

Is it possible (and if so, a hint would be appreciated...) to have separate config files or separate config file sections for a number or custom user controls?

for example, say I've got a page with a "Latest News Display" control as well as a "User Poll" control. I'm looking to store things like the db connection strings in a "web.config" file.

Barking up the wrong tree or just a bit slow?

TIA.

Beauty! Thanks much..

(So does that prove that I was just "SLOW"?)

Nah it just proves MS loves to hide stuff in their vast ocean of documentation..

Is there anyway to display an ActiveX in Netscape browser? Usual OBJECT tags doesn't seem to be working there (using NS 6.2)

Philip Patrick

ActiveX isn't supported in Netscape. I'm certain of this in 4.x, and I'm willing to bet this is also the case in 6.x. ActiveX is a Microsoft technology and is not an industry standard.

Hmm... kinda strange, OBJECT tag is in HTML 4 specification and it has "classid" attribute. From my point of view of Windows programmer, class id means GUID of the COM/ActiveX object.. But Netscape says it support HTML 4 in NS6 (incl. OBJECT tag), but looks like I can't use ActiveX GUID in it. So I can think about 2 ways - Netscape lies and it doesn't support HTML4, or "classid" is something else and not what I'm thinking. Then what is "classid" in Object tag?

A class id generally is a GUID but doesn't have to be in theory. This is not related to ActiveX other than the controls use them. Support for the object tag doesn't mean ActiveX support. Other instances of using the object tag would be for RealAudio/Video, Flash, etc. It's still up to the user agent (e.g.; Netscape) to interpret the object data. Ever notice you have to install plug-ins for Real and Flash? It's processed by the browser. The HTML specification doesn't cover this.

Hope that helps.

Is there a way to set the focus to a particular control, like an edit box, on a server page when it loads?

Thanks,

Marc

Server page? It is a client task.
You can create a javascript which will set focus to control. Like in onload handler of the body tag:

document.getElementById("myeditbox").focus();

Sorry for such a simple question but I can't figure it out.
In my ASP code I get Some HTML code from some COM server then I try to find some string, say "something" in that HTML and InStr fails because it actualy is looking for "s o m e t h i n g " in there and of course can't find it. How do I tell ASP code to use regular strings? Confused | :confused:

Function RegExpTest(patrn, strng)
  Dim regEx, Match, Matches      ' Create variable.
  Set regEx = New RegExp         ' Create a regular expression.
  regEx.Pattern = patrn         ' Set pattern.
  regEx.IgnoreCase = True         ' Set case insensitivity.
  regEx.Global = True         ' Set global applicability.
  Set Matches = regEx.Execute(strng)   ' Execute search.
  For Each Match in Matches      ' Iterate Matches collection.
    RetStr = RetStr & "Match found at position "
    RetStr = RetStr & Match.FirstIndex & ". Match Value is '"
    RetStr = RetStr & Match.Value & "'." & vbCRLF
  Next
  RegExpTest = RetStr
End Function
MsgBox(RegExpTest("is.", "IS1 is2 IS3 is4"))

This is different. you are looking "ASP" string in "ASP" string. And ASP
is using unicode. But my problem is different. I get regular, non unicode string from a control and then attempt to find something in that non unicode string and I can not because in fact under the hood it is looking for
"c 0 c 0 c 0" when in that non unicode string there is "c0c0c0". So how do I tell ASP to use regular strings in comparisons or how do I convert that non unicode string to unicode before searching?

Ooohh... I see. Here you're talking about ANSI to UNICODE problems and I thought you were asking how to do regular expressions... Eek! | :eek:

Check out http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnasp/html/nextgen.asp?frame=true

According to this article you just set the code page and ensure that you assign the string returned from your component to a local string variable to perform the translation. Hope this helps.

Somedays before , I met a strange thing that my IIS stop working itself.I must reboot the system,then it worked again! who can tell me the reason?
My system is win2000 Chinese-simple and IIS is Ver5.0。

But no seriously, that's not enough info to go on. Check your event logs for errors.

I have installed SDK and Microsoft.Web.UI.WebControls.
Did a small asp.net to test the tree view control and getting the following error
"Could not load type Microsoft.Web.UI.WebControls.BasePostBackControl from assembly Microsoft.Web.UI.WebControls, Version=1.0.2.226, Culture=neutral, PublicKeyToken=31bf3856ad364e35."

Can someone please tell me what is happening here.
