I thought I would just put together a quick page in ASP.NET to replace the old one I have written in ASP that uses the Dundas control.
Anyway, nice and easy, especially with the articles on this site, 10 minutes I have an upload/Download page and a database (SQL2000)
My only problem is it does not work 
I have the following code where theFile is a HttpPostedFile object.
1: byte[] myData = new byte[theFile.ContentLength]; <br />
2: theFile.SaveAs (@"c:\test.jpg") ;
3: theFile.InputStream.Read(myData, 0, theFile.ContentLength);<br />
4: dbRow["FileData"] = myData ;
Now, line 2 works fine and I can see the picture saved onto my hard disk, but line 3 does not, the myData array remains full of zeros, but it is set to the correct size in line 1.
What started as a 15 minute job is now taking hours.
Anyone else seen this problem or know what I am doing wrong here?
Thanks
Stephen.

Found the answer in the end, just needed to reset the InputStream's position to the begining of the file with
theFile.InputStream.Seek (0, System.IO.SeekOrigin.Begin) ;
I had assumed that it would have thrown an exception if it had tried to read beyond the end of the stream.

I manage an Intranet and have been having some problems with some files (.xls, .doc, .ppt, etc.) getting cached into memory when a user downloads them. If the file gets updated, certain users still see the old version for anywhere from ~1 day to ~1 week. I tried everything from refreshing/reloading the pages to clearing all temporary files from the computers but I cannot find a way to force the browser to download the latest version of these files. One thing that confuses me is that this only happens to some users, even though we are on an Intranet with standard computers and standared program settings.
I threw together the following script that solves this problem because it tricks the browser into thinking that it is downloading a file that it has never seen before by assigning it a random variable at the end.
<script type="text/vbscript">
randomize()
document.write ("<a href='filename.xls?id=")
document.write (CInt(RND * 2000))
document.write ("'>Link Name</a>")
</script>
Does anyone have any comments on this or know of a better way to do things?

There is a pragma-no cache directive that can be inserted as a meta tag in the header of the html document. I cannot remember it exactly the syntax.
However, the proxy server might cache some html documents, which is generally bad news. In this case the user might hit CTRL+F5 million times and still a cached version will be retrived.

This works for the HTML page itself, but not for the other files (non-HTML documents) that the page is linking to. In my case, I am trying to prevent Microsoft Word, Excel and Powerpoint files from being stored in memory.

Hello,
I am using layers for Netscape 4. After defining layers, I am using HTML controls like input box, submit buttons. But these controls are not being displayed after defining layers. If I define these controls before defining layers, these controls are visible.
Can anybody tell me what is the problem?
Thanks

Well my first piece of advice is not to use Layers. But since you already are and probably won't change...

Couple things. Make sure you have wrapped the INPUT elements in a FORM element. Netscape sometimes displays INPUTs without a FORM element, and sometimes doesn't. So rather just put the FORM element in.
Another problem is that your LAYER is "covering" the INPUTs. Make sure it's top and left attributes are out of the way of the INPUTs.
Better yet, post the code and I can help.

Well I use MS Visual Studio 7 to write my markup and modified the colors.
Well it takes me have an hour to post a code snippet like this one  .
Currently I'm writing at a XSLT stylesheet to format markup, cause it takes way to long to do it by hand. Maybe I'll write a C/C++ converter but that's not that easy (who would have thought that?)
Here a little guide:
Put all code in these tags
<nobr><div
style="background-color: rgb(225, 240, 255);
color: black;
font-family: 'Courier New', monospace;
padding: 2px 2px 2px 2px;
margin: 5px 5px 5px 5px;
border: solid 1px silver;"
>
<nobr>
* Place your code here *
</nobr>
</div>
Use 2 s to indent every step.
And this is the hard one: color every element by hand with <span style="color: [color];">* Element *</span>

Can anyone point me in the right direction in regards of how to develop a file manager system?
I would like to create one for my website so I can share files, upload/download.
I don't want to buy one.
Is this possible in ASP w/ VBScript or JavaScript??
much thanks ,

|

|

Yep, of course it is possible. You should use FileSystemObject for this purpose (make sure it is available on your site). It has all needed capabilities - creating, moving, coping, deleting, renaming, listing directories and files

http://www26.brinkster.com/mvark/scramble.html is my attempt at rot N encryption similar to rot13 encryption in which each char of submitted text is replaced by the 13th char ahead of it. to decode the encrypted text, u need to provide the negative value of the number u used to encrypt. the instructions to use the app are on the page itself. it uses javascript and works with ANY [?] user specified number.
i could not conclusively arrive at
1] the largest number that can be used
2] why certain characters don't show up properly on decryption while
other characters do. for instance character 'i' when encrypted with
number 55 generates a
char which when decrypted back with -55 does'nt give back 'i'
To take corrective action and convert this into an article I look forward to any feedback on this....
this is the function that does the encryption/decryption
function scramble(num){
ascram= new Array();
bscram= new Array();
scram=document.myform.original.value;
ascram=scram.split('');
for (itemp=0;itemp

The rot N algorithm is one of the oldest methods to encrypt text (maybe 3000 years old). Take the english alphabet for eaxample, which has 26 characters.
If you move every character 5 digits above your 'a' would become an 'f'. Easy. Now what about the 'v'? Adding 5 digits to 'v' would result in the 27th character of your alphabet, wich is not defined. Now how can you solve this? Quite easy, because you moved the 'a' five digits up, you get a space of 5 digits at the beginning of your alphabet, so all shifted characters above 26 resume at the beginning of the alphabet.
Every ASCII character has 256 possible values, so you have to set the cutting edge to 256.
This function rotates your text n wise:
<nobr>function rot(text, n)
{
var result = "", character, position;
n = (n % 0xFF < 0) ? (0xFF + n % 0xFF) : (n % 0xFF); // rotating -10 is the same as rotating +245
for (position = 0; position < text.length; position++)
{
character = text.charCodeAt(position);
character = (character + n) % 0xFF;
result += String.fromCharCode(character);
}
return result;
}
I wonder how you get an 'a' by adding something to 'i'. 'a' has the value 97 and 'i' the value 105?!
Ok, after sleeping over it twice I found 2 errors in my first try:
1. Negative n values, that resultet in a character value < 0 created garbage.
2. Numbers > 255 (0xFF) could also create problems.
Both fixed.

Question:
Why is it such a bad thing to keep my connection string inside any *.php file...??? I've read from differ sources that so long as your database password/username are used inside PHP and your webserver is setup correctly this posesses no problems... (assuming because any PHP is exeuted on the server before being sent to the browser as PLAIN HTML?). However I have also read that you should store your database connection routines in an external PHP file somewhere other than your docroot and include into your main PHP code using require() or include()
What the hell does that mean...??? my doc root I am assuming is the directory on the server which is mapped to my IP/domain name???
example:
home/domain/mainwebsite_html
home/domain/mainwebsite_bin
However I don't think I can transfer files anywhere other than child folders I create or in the two listed above...or can I...??
If I FTP'ed a file under just home/ would this be considered somewhere other than docroot..?? if so why is this the safer method...??
Thanx in advance

Yes. On a Unix box running Apache, you may see something like www, public_html, etc. where the actual document root is. It's rarely the same as your home directory for a virtual domain.
Hockey wrote:

Because it's not publicly accessible to everyone - which has to be done in order for web pages to show up in the browser.
If you can admin the system on your own, I would suggest keeping everything related to your webpage in the document root, however, to make it easier to move around. Create a "passwd" subdirectory and chmod that sucker to 750 and put the include file in there and chmod it to 640.
Note that the user Apache/PHP runs as will affect its access. Apache may be ran as the user nobody, or something similar. Which means there's a chance it might not have access to that folder you just created. So, either chgrp the "passwd" directory you created or change the user/group combo that Apache/PHP runs in - if it doesn't match.
If you can't admin the system, then just keep it outside of the document root as a quick fix. This still will stop anyone from the web from seeing it.

hey all,
I've been writing some ASP.NET with VB.NET recently. So far I have *not* been able to publish things by copy/paste to my ISP, brinkster. So what I've ended up doing is modifying the VS.NET generated page, taking out the code behind and inherit directives and writing everything in one single page with embedded ASP.NET (a at the top).
This seems to do the trick.
When I'm running things locally though I've also noticed that a "View in Browser" doesn't work with the codebehind etc... and istead I have to use the "set start page" and let VS.NET compile everything first.
Am I just not deploying things correctly to my ISP? How can I compile things locally and then just copy them over to the server?
Thanks much,

Is there any way to detect when a form is submitted using the form.submit() method?  Thanks.

From the client side...???
I've never tried it myself but
<br />
<input type="submit" onSubmit="alert('onSubmit detected');"><br />
should do the trick
