Create filter using distinct values

I am trying to figure out the best way to create a filtering user
control. I have 3 fields I am using and therefore have 3 combobox's
that all need to display distinct values. The resulting functionality
should be that the user selects a distinct value from the first cb, the
other 2 are filtered by that value selected, the user selects the third
value and the second is then filtered by the first and third values.
Can anyone think of or does anyone know of a way to do this? The
dataset is rather large so i cannot use a full select. Thanks in
advance.

Imagine I have a dict looking something like this: myDict = {"key 1": , "key 2": , "key 3": , "key 4": } That is, a set of keys which have a variable length list of associated values after them. What I want to do is filter out a subset of this dict to produce another dict that satisfies a set of criteria (in this case whether it contains all four values) to end up with something

I want my users to be able to select a report, click on a command button on a form, which will then automatically create the report as a pdf file and save it to the user's machine. I am using Adobe Acrobat (5.0 I think) and have Adobe Distiller as a

I've read that the expression property for DataColumns is used to "Sets or retrieves the expresssion used to filter rows, calculate the values in a column, or create an aggregate column.". I have seen examples on how to filter a column, but how would I filter out an entire row depending on the value of a column? For example, if I wanted to filter out every row in a multi-column table where the "Is Fubar" column equals "true", how would...

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...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
