Net or Java one tends to believe that it's planned to use exceptions as normal program flow stuff I don't know how the poor performance fits in that concept! ZombieSheep ZombieSheep 29k 11 11 gold badges 65 65 silver badges bronze badges.

If the caller does not have sufficient permissions to read the specified file, no exception is thrown and the method returns false regardless of the existence of path. The Exists method should not be used for path validation, this method merely checks if the file specified in path exists. Passing an invalid path to Exists returns false. Any suggestions? I want to avoid duplicate files so how can I check to make sure the filename of the uploading file doesn't already exist?

I want to do something like. I'm building some dynamic image links based on if the image file exists. How can I check 'if files exists' using asp or javascript? I've messed around some with FileSystemObject but so far no success. Some sections of the web site don't have a "menu.

Is there a way to know if a page exists before using xml. I want to upload images from people and save the name of the files in a database so I can later populate from there. The uploading part is working fine, except that when I use SaveAs, if the file exist it rewrites the existing file I did do a search in the forums and tried to use a code that memnoch posted but it wont work since the aspsmartupload objetc doesnt support the FileExist Method I have code that loops through a directory reading files..

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 have a problem. I tried my best but could not solve is. I have a page where user selects the folder name from a drop down list.

It takes user to show. If I select name of the folder from the list, on show. When I click on the link then most of the file which has long name and have space in their names wont be hyper linked.

For example if files name is Virus Control.
