Invalid Path Character -server.mappath function

[lpatnaik]

Hi I am getting this error "006~ASP 0173~Invalid Path Character~An invalid character was specified in the Path parameter for the MapPath method.", while using the Server.MapPath function. Can anyone tell me what all characters are not supported by this function or does Microsoft has any list of such characters, so that i can validate which characters can cause problems.

Known is handfull, Unknown is worldfull

The most likely problem -- without seeing your code -- is that you typed a slash (/) instead of a backslash (\) when specifying your path. Server.MapPath doesn't seem to like that -- it's a DOS thing.

I know I've done it more than once.

I am using this code..

Server.MapPath("../../images/designers/" & DesignerPicName & ".jpg&quot

This picks up the image file from the images/designers folder. Since there are thousands of jpgs in this folder, i wanted to know what could be the possible invalid characters. No "\" or "/" is definetly not the issue here.

like Genimuse said:
Server.MapPath("../../images\designers\" & DesignerPicName & ".jpg&quot



Known is handfull, Unknown is worldfull

The files are already on your server, ergo their names are valid.

Server.MapPath doesn't have any special valid or invalid characters that are any different from the operating system's.

response.write out the full path to see what is tripping up server.mappath just in case there is an extra "/" or something else added to DesignerPicName or if indeed it is empty.
Depending where (and how) this variable is assigned a value, all or any of the above could occur.

been there, done that,

More code will help

The problem here may be the ..'s. Make sure in IIS that you have allowed the option for those folders to access their parent folders. To enable this option in the Internet Services Manager, rt click the web server you wish to edit (default for example), select properties, click the home directory tab, select configuration in Application Settings, select the App Options tab, Click the Enable Parent Paths option. That will give children directories permission to accesss filers through their parent directories. If it is not already selected than that is likely your error in this case.
