View 8 RepliesI have declared two variables as strings strDob and strCurrentDate, Both Variables are for storing dates. StrDob is for storing Date of Birth and second is for Present date. and am executing the following code
If DateValue(strDOB) > DateValue(Date.Today) Then
and getting the error like
Invalid CastException was unhandled
Conversion from string "19/09/1987" to type 'Date' is not valid.
Error in the following code also:
iAge = (CInt(Abs(DateDiff("d", strCurrentDate, strDOB)) / 365))
Invalid CastException was unhandled
Argument 'Date1' cannot be converted to type 'Date'.
Here I need both variables as string itself. because the Dateofbirth is getting from three comboboxes.

running my app in Debug Mode within Visual Studio I've been able to allow the user to Open an Access Report and if need be print it off. This has worked great.Unfortunately when I run the .exe file I get the following Unhandled exception message.'Could not load file or assembly 'Interop.Access, Version=9.0.0.0, Culture=neutral, PublicKeyToken=nuill' or one of its dependencies. The system cannot find the file specified.'Like I say above, this works when run from within Visual Studio, the code as far as I know is not the problem.

As you can see i am wanting to use linq to remove duplicates, and also because i want to use the union and except statments elsewhere.
The above is fine if the filesize is about 150mb but with 250mb it throws a out of memory unhandled exception, on 'sWriter.Writeline(sline).
