I'm trying to do the most simplest of things... open a text file. Not System.IO, just plain open a text file like you would double click it in widows.I have no problems executing other exe files with the Shell command but when I try:
Code:'...some code
If System.IO.File.Exists(FILE_NAME) = True Then Shell(FILE_NAME)
'some code...
I get "file not found"...
But if I do:
Code:'...some code
If System.IO.File.Exists(FILE_NAME) = True Then MsgBox("File Exists") Else MsgBox("File Does Not Exist") End If
'some code...
the message that pops up is "File Exists"!I also checked the FILE_NAME in a msgbox and the file path is correct.What could be wrong?
I have the following search code which works fine. However, I have an additional task to do, which is create a count function for the Record found or Record not found. Presently what it does is it searches and if a record is found it displays at the tooltip "Record Found" if not it says "Record Not found". However, sometimes you have 2 or more records. Therefore, the tooltip should say the exact amount of records found.. For example, 3 Records Found or even 5 Records Found. Also if only one record is found it says "Record Found" but if more it should display " 2 Records Found".
