What is the way to :
1) Check if a file exists on an FTP site.
2) Sample the size of that ftp file (3) times to ensure the file is ready for downloading.
We have some classes doing this already but they are using WebRequestMethods.Ftp.ListDirectoryDetails and then searching there in if file exists. I am hoping there are some clean ways to do this.
I have two websites. One site contains nothing but image files. This is a sub-domain of the main website. The main website allows the user to search a database of information and displays that information. I create a grid with a link to the file. In my row_databound function, I want to check to see if that file exists on my other website. If it doesn't I remove the link, otherwise I leaves a link to that file. how to verify that the LINK actually goes to a file that exists?

View 3 Replies i have a site that will enable users to download an ebook file.i have successfully built architecture to enable users to download pdf and txt files, but it won't work when i try with a .mobi file, even though i know the file exists.the site works by allowig users to upload their work as .doc, .docx or .odt. once it's verified, the site publishes it as .pdf, .txt and .mobi and makes it available for download. the download code is...
string mstitle = title.ToUpper();
string dlpath = [the server path] + msid + mstitle + ".mobi";[code]....
(there are also versions with .txt and .pdf) the file definitely exists at the location in .txt, .pdf and .mobi extensions. however, the .mobi version simply won't work i get an error 404 resource not found. mystifyingly, the pdf and txt versions work perfectly.

View 1 RepliesI'm having some trouble trying to create a page for my web app. I'm not trying to write a simple download/upload page. Should also say that I'm not trying to write a complex one.What I need to do is in the PageLoad check if the user has installed one particular software and then show the right message to download and install OR run it from the user's actual installation. For this scenario I've tried to use different file upload controls to check if the file was on the client machine, but none of then can do this, since, for security reasons,I can't programmatically set the path and file to upload.

View 1 RepliesI have a page with a simple textbox, when an OrderNo is entered in te textbox the page is populated with 2 or 3 gridviews depending if the order has items reserved or on back order.
GridView1 has data about the order, like status, payment details.
GridView2 has data about orderitems, each row displays an item from the order with stock and order quantities
GridView3 has data about backorders, each row displays an item from the order with quantity reserved and quantity on back order. As is no data for GridView3 if order is not on backorder I thought that I can enclose my code inside an if block
if GridView3 isnot nothing then
'getting some data from the cells in GridView3
endif
but the code still executes.
I have some data that I am putting on a treeview and have a checkbox on the page to decide if the user wants to order the nodes by date or type.
To do this I need to check if the code has already added a child node so when grouping by the type I don't put it in lots of times.
Lets say I have Type 1 and Type 2 and each have 3 items that would fall under these I want to achieve:
Type 1
Item 1
Item 2
Item 3
Type 2
Item 1
Item 2
Item 3
Instead of:
Type 1
Item 1
Type 1
Item 2
etc etc etc
I tried using the node.Contains function but it doesn't seem to exist (I am using c#).
