I am developing an web application, it should has the function to upload file from client computer. The uploaded file size can be limited within 10 MB.
But I dont know how to check the size of the file on client-side. Server-side size check is not enough, because it can not be checked until the whole file is received while the server resource(cpu,memory etc) is wasted.
I'm having a problem with the fact that I want to allow image files to be uploaded to a remote web server, as the hosting package the web site is on is IIS6 and has a default file upload size limit of 200kb. As it's a shared hosting package, the default limit cannot be changed for me unfortunately.
Anyway - i need to check the size of the file being uploaded, so i can notify the user and prevent them getting the default Microsoft error message page. The problem is that I can't implement a server side size check which works, using either Request.TotalBytes or load.getFileSize (with "load" being an object of my loader class). It seems that I can't carry out any of these operations when the file size is too large.
I have a regiseter form, which contains like 35 fields and most of them are must fields.
So if user enters all and submit and if username happens to be duplicated then i have to get all the values and put it back and ask him to change the username / or other option is only ask him to change the username/ in both cases i have to keep all the data and feel unsafe and inconvenient.
So is it possible to write a function in on change event in the text box,in which he write the username, and check if that name exists pop up a message saying username already exists.
is it possible to open an excel file (used as a template) from server using server-side vbscript; then modify it or add values from client using client-side vbscript?

Is there a way to check the file size before the page submits? ie a javascript function that i can call before submitting the page?

I have a need to transfer a graphic file to a user's system and then
access that file. I must have the drive letter:path location of the
file. If at all possible I'd prefer that this not require user input.
(Note that since this is my app and in a corporate network, I have the
server in the Trusted Sites zone and every single action is marked
"Enabled" in the IE security settings and users will be using IE
exclusively.)
It doesn't matter to me how the file gets to the
client, save that it get there from IE, and the file is initially
retrieved via a url I give the client. I have even looked into
reading the file out of the IE temporary files but have had no luck.
I need a client-side check against a static list of "banned words" before a form is submitted. Can someone point me to a script that does this?
View Replies View RelatedI have developed a windows 2000 based web-based
application which uses only HTML and JavaScript code for the
client side and C++ on server side .
Now i need to implement a feature to implement "writing the
log file" on the client machine for this application. As
JavaScript doesn't support client side file writing i think i need
to use ASP or similar language.
1. Is it possible to write on client machine using ASP??
2. If it is possible please thow some light on how to implement
this.
3. Will my code be stable if i embedd the ASP code into the exisiting HTML & JavaScript code?
how can i copy i file from server to client side ... any solution or can it be?
View Replies View RelatedWhat I'm trying to do here is have the user select a file of thier local machine (dont know what format to make the file yet, examining this problem b4 development) From that file, certain fields on the page will be populated automatically. The file they will select will have been saved from a visit to a different site I created so no worries about formatting.
But I can't seem to figure out how to do this without actually uploading the file.
To repeat, I just want to examine the file and be done with it. If I can't do this without uploading, then could someone explain how I do that because I've been having trouble finding a source that doesnt want me to buy thier .dll. I find it hard to believe that IE would implement input type=file and IIS would not have it's own method of getting that file.
send me the code for creating text file on client side through asp. or is there any way to direct copy a file from server to client without asking to downloading the file?
View Replies View RelatedIs it possible to delete a file on a client side machine using VB/JAVA script?
My website allows the user to upload a file to the website and after that I would like to delete the file on their machine tried this:

I got a script for uploading files that sets its file size limit to 10240kb. The line in that script Code:
Const MaxFileSize = &H100000

I had my server run win2K SP4 running an ASP site that uses ABCUpload and all was working fine. Today I have found that we can no longer upload files greater than about 4Mb.
I think way back when I set this site up I had to change a setting some where in windows that allowed the site to accept file greater than 4Mb. Does any body know what this setting is and where I can find it.

How do I go about calling a server-side vbscript within a client-side
javascript function? What I have is a page heavy on the javascript that has
a number of functions, one of which is to begin a visual countdown with an
onclick and also open an asp page containing the server-side vbscript, which
initiates a wake-on-lan call. I had no idea how to call the vbscript within
the javascript function, so this is why I opted for the vbscript asp page
"pop-up" via window.open. Code:

I am starting to build quite a few pages that will have
tables of data from an SQL database.
I have been building the table rows on the server side
in VBScript, but I have been thinking about having the
VBScript code just build array variables in the <head>
section (or as local variables), and then have JavaScript
functions on the client side actually populate the tables
when the page loads.
I do plan to do other things like being able to sort the
tables in JavaScript code on the client, limit the tables
height and be able to scroll the rows, and click on a row
in the table, and have the values populate a form. I will
also need to be able to export/download/? some tables into
Excel.

Is there an ASP method for obtaining the size of the clients display area? Think I can think of a method(havn't tried it yet) combining JavaScripting and ASP, but I was wondering if there was a strictly ASP method.
View Replies View RelatedThis has happened before and it was due the connection string not being set
in VB. My question is, when I try to reconnect can I use a different
connection string on the client than I have on the server, I wonder because
not all my connection strings are not equal.
Some of my database paths are in Access and the rest are in SQL. That means I have to retry several times before a scrip timeout occurs. If you have read this far then you are an idiot, but the rest of the database seems to work just fine. In fact I can
pull all fields out with no problem. It is just that connection string that
has resulted in causing my pages not to post.

We want to create an Intranet page for our customers. which provides a variety of information. But we also want to be able to allow users to access applications on that PC by clicking a link on the page (ex. link: WRITE A LETTER - opens MS Word). All PC's are imaged the same way so the applications are always in the same location.
I'm sure this is a violation of MS security inherent in IE, IIS, or in Windows XP alone. Can someone offer an advice - as to (1) is this possible using an Intranet page; or (2) is there a development environment that it would be possible in?
