Sign in to vote. User posted Hi, I'm having some trouble trying to create a page for my web app. Thanks a lot!!! Wednesday, January 6, AM. How can I check if a file exists on the client? I have a form which requires the user to upload a document from their computer. In the event they don't enter a valid path to the file the form does not submit. How can I check if the file exists and if it doesn't, provide a suitable response?

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. Using ASP with VBScript is there a clever way to easily check if a value exists in an array without looping through it?

We have two tables EmpProfile and holidaysrequest tables. I want to write a query which will be used by ASP page to display everyone who have not booked 29th - 31st Dec as days off. I have built a page that lists all our databases, the users connected to each database, and what application they are using.

Because these databases are moved, or removed from time to time I need to check if the database still exists before trying to query it. I populate a recordset and dump it into an array. How can I check if a value exist in the array? Recordset" rs2. GetRows 'Close Recordset to use the new array with the 2 columns data rs2. I mean from the code side. I dont want it to throw me any error thats the reason.

How can i check to see if an array specifically a session variable, if it matters exists or not? I get the table name from the user and will have to check whether the entry that he has given is a valid one or not.

I am working on a image gallery and am trying to show images from different websites. Before I display an image I need to know whether that image exists on the other server and only display it if it exists. Does anyone know how I can check to see if an image exists on another web host?
