Having difficulty with the module below failing on line 21. It is telling me: The system cannot find the file specified. (Exception from HRESULT: 0x80070002) Basically what it is designed to do is look for a directory, if that exists then look for a file in that directory. If both = True then it should open the folder to browse the files. I believe the issue is with the "Program Files" being 2 words since the script runs using a root path, but I'm not sure how to format the path correctly to make it work?

I've created a little procedure that I use to verify if a value does actually exist. I'm currently using this all throughout my application for things such as verifying if a control's EditValue actually has a value. I was wondering if I have missed any scenarios where a value would not be available, missing, non-existent, blank, etc., and how would I incorporate in my procedure.
Public Function ValueExist(ByRef CheckValue As Object) As Boolean
Try
ValueExist = True
If IsDBNull(CheckValue) Then
ValueExist = False

i have a series of CSV files that are posted to a specific web folder that I can specify in network places. Each file has same structure, lots of fields, and have consistent name schema "prefix-mm-dd-yyyy.csv". i need to use VB to process all these files, either individually or by consolidating into one file and appending to an existing table. i also need to somehow add a "download date" field to the process so i can show when the file(s) were appended. then i need to verify that it worked ok so i can then, still within VB, move the files out of the folder, such only the CSV files that have yet to be imported/appended are in the folder (so I don't have to guess about which files I have already uploaded and processed.i can figure out how to make a DO UNTIL loop, but i can't get the import statement right... nor can i figure out how to verify that the import happened in order to move (or remove) the source files.
