Saving HTML file to MemoryStream
Hi,
I currently save updated data to a text file formatted in HTML using StreamWriter. The file is named PP.Html. I use the Web Browser control to load PP.Html and display the updated information. Is there away in VB.Net to save the file to a MemoryStream and Load it with the Web Browser control? If so, please provide an example. I've searched but only find examples on saving images to MemoryStreams.
Any help is appreciated.....

Re: Saving HTML file to MemoryStream
in ur form load:
AxWebBrowser1.Navigate2("about:blank")
in the event of AxWebBrowser1_DocumentComplete...
WriteWebPage()
write a sub as following:
Private Sub WriteWebPage()
Dim fStrValuePassed As String
Dim myDoc As HTMLDocument
myDoc = New HTMLDocumentClass
myDoc = DirectCast(AxWebBrowser1.Document, HTMLDocumentClass)
myDoc.body.innerHTML = fStrValuePassed
'fStrValuePassed is the html code....
End Sub
And very important!!! import the reference microsoft.mhtml from the .net tab....

Re: Saving HTML file to MemoryStream
Hi,
Thanks for the help. It works great, no need to save to file, however is it because i'm inserting into the body that I loose the spacing when I view the page in the browser control.
This is a bit of what I created using stringbuilder.
<html>
<head>
</script>
<style type='text/css'>
<!--
body { font-family: PLHIRL+PaddockExt600700,Arial, Helvetica, Verdana, sans-serif; font-size: 9px; color: #000000; background-color: #FFFFFF}
.pos { position: absolute; z-index: 0; left: 0px; top: 0px;}
-->
</style>
</head>
<body id='6' onload='' >
<nobr>
<div class='pos' id='_2:25' style=' top:25;left:2'><b><i><span id='_10' style='font-size:12px'><font color ='#000000'><span style='letter-spacing:-0.38 px'>Past</span> <span style='letter-spacing:-0.78 px'>Performances</span></i></b></div>
<div class='pos' id='_358:25' style=' top:25;left:358'><b><i><span id='_7' style='font-size:12px'><span style='letter-spacing:-1.30 px'></span> <span style='letter-spacing:-0.52 px'> 04/16/2005</span></span></i></b></div>
'More lines here
'
'
'
</nobr></body>
</html>
The fonts are correct, just the positions of the text is lost...
Again thanks for your support..

Re: Saving HTML file to MemoryStream
I'm not quite sure abt ur question...
Assuming that i got ur question right...,
Try not to use too many span tags unless if it's really required.
If ur using frontpage tool to do this formatting... span tags r repeatedly created when u make too many changes. Redo the formatting in frontpage or any other tool ur using.
I don't think there's any limitation in the IE control coz I hv been doing many of these type apps b4.
