Crystal Reports: Login failed when trying to add database to report

In the crystal reporter.net designer I tried to add a
dataset to the "DATABASE FIELDS" node of the Field
Explorer tree. I get the following Messagebox:

Logon Failed
Details: Object reference not set to an instance of a
object

The message box title is "Crystal Reports ActiveX
Designer"

I tried adding other datasets in the project and they
work. What are the possible reasons that my dataset is
not working?

Thanks...

I need some help please! Crystal is driving me nuts. Heres my code so far, see below. Problem: On the .export() line it comes back with error #5 Login failed! I know the login info is good so why is the bloody thing doing this. The paths have been checked and are correct. The crystal Report is a .rpt file. Not one created in the VS.net IDE but in crystal itself.

Hello, I need help. I have experience in ASP.NET programming, but this is my first dealing with Crystal Reports. I'm trying to make the most basic report purely for testing purposes: connect to the remote SQL DB and create a report on one of the tables.

I'm developing an VB.NET Windows Forms application that uses CR for VS.NET (original version shipped with VS.NET 2002 - my VS.NET has the latest SP installed, no SPs for CR).

Fine, I know how to do that and it works perfectly on my development box. The...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...
