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?

View Replies View RelatedI 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?

View Replies View RelatedWe have two tables EmpProfile and holidaysrequest tables.
EmpProfile has fields
EmpNo

holiday requests table stores the dates employees have booked as holidays.
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. Otherwise I get
funny SID errors when it tries to process this command:-
Conn4.Open "Provider=OraOLEDB.Oracle;" & _
"Data Source=CD;" & _
"User Id=username;" & _
"Password=password"
Can this be done in ASP or should I be querying the error
collection or something?
I populate a recordset and dump it into an array. How can I check if a value exist in the array? I want to check if the c_Member_mgr has a particular value or not?
Dim rs2
set rs2 = Server.CreateObject("ADODB.Recordset")
rs2.open sub_Emp_Source, Conn
Dim aSubordinates
If not rs2.EOF then
aSubordinates = rs2.GetRows()
'Close Recordset to use the new array with the 2 columns data
rs2.Close()
set rs2 = Nothing
'Declare Constants for the above SQL columns for better readability
'Use these Constants instead of referring to the array numeric indexes
Const c_Member_Mgr = 0
Const c_Subordinate = 1
Const c_EmpID = 3
Const c_EmpName = 4
there is any way i can check if the database Exists. I mean from the code side. I dont want it to throw me any error thats the reason.

View Replies View RelatedI have a web page that creates dynamical forms, depending of what kind of product it regards. When the user has chosen a product, data is collected from SQL Server and a form is created.
Some forms contains check boxes and some not. My questions is: How can I check if someone has UNCHECKED a check box? Because if that happens, I want to delete that entry from the database.
Since a form just posts the value of a check box if it is checked, this causes a dilemma.
Any ideas, I can't be the first one having this problem?
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.

View Replies View RelatedI have code that loops through a directory reading files..
now the problem is that files are constantly being uploaded and I only want the file system object to read those that are finished being uploaded.
How can I check the properties of the file to see if it's in middle of being written before i read the file?
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 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.
im creating an asp using the file scripting object but i cant create the file in the local pf of the client, but rather saves on the server folder.
