Using Access 365. I would like help building code to achieve the following please, I’m trying to streamline adding images to a record.
I would like to use VBA that on clicking a button will save an image as a .jpg from the clipboard (put there by User using Snip tool) to a subfolder of the database, then pass a relative link to this file to the form. I’d like to be able to attach multiple images’ links to a given record in this manner.
Using the code below (without the AltPrintScreen element) I’ve gotten as far as saving from the clipboard and generating an absolute link, but only as a .bmp. (https://www.access-programmers.co.uk/forums/threads/print-screen-into-image-file.245198/). Grateful for any help getting the rest of the way, or suggestion of an entirely different way of doing it. Cheers!

...ANSWER
Answered 2022-Mar-08 at 20:38I've created a solution that does what I want. I've used four Modules I found on various sites and then created a bit of VBA to pull the tasks together in the background.
- Module 1 is the one I posted in the question above. I bypass the AltPrintScreen part of it so it doesn't overwrite the image already in the clipboard.
- Module 2 Converts the BMP created by Modules 1 into a JPG.
- Module 3 Scans a folder and populates an unbound listbox with a list of the files found there.
- Module 4 is used to make the filepaths in the listbox act as hyperlinks to open the images on clicking.
I then created a button on a form that calls the first two Module to create a jpg from the image in the clipboard as follows...

I am using custom UDT type to store place information . It is stored as frozen blob/serialized type in table . For sorting based on country and state . How much sense it make to keep UDT type as clustering column . Will all serialized value of place having same country and state grouped together.
...ANSWER
Answered 2022-Jan-09 at 18:52As far as I know, there isn't any restriction on using UDTs as part of primary key. Back in the initial days, the use of UDTs was discouraged inside primary key (http://www.datastax.com/dev/blog/cql-in-2-1). The primary reason I believe was because UDTs at that time was mostly used for simplifying complex types within collections.
Nowadays, the pattern I believe is quite readable and should be fine to use in my opinion.

I know that for scalar types you can assign values with braces like int a { 0 };
.
This helps with cast, type conversion ecc.

I'm trying to create subclass item_t from base class base_t, but it gives me errors:
PLS-00539: subprogram 'ITEM_T' is declared in an object type body and must be defined in the object type specification PLS-00538: subprogram or cursor 'ITEM_T' is declared in an object type specification and must be defined in the object type body

This is the sample request payload that is being sent to insert into the oracle stored procedure:
...ANSWER
Answered 2021-Nov-10 at 11:58You are using the stored procedure operation of the Database connector in a generic way, ie the parameters and the query are passed dynamically. That works for base types, but for arrays and user defined types it requires them to be constructed with special functions Db::createArray() and Db::createStruct(). Also you may need to specify the types in the database connector configuration.
QUESTION
I am recreating an older VB6 program that reads random-access files created using another VB6 program in VB.net. Backwards compatibility is essential for the new VB.net program. There are thousands of files that have been written that need to be accessed. There are five lines to each of the files when I open them in notepad++, though I can't make heads or tails of the random characters in notepad++. The files should contain four records, so I am not sure what the fifth line is for.
I have access to the old source code for both programs. Below are the VB6 read and write methods.

...ANSWER
Answered 2021-Nov-08 at 21:27Arrays of the sort you see in these VB6 Types are not SafeArrays. They're actually vectors, and as such can be replaced with a sequence of the underlying variable: x(3) As Single
can just be x1 As Single
, x2 As Single
, etc in Vb.Net. In contrast, x() As Single
inside the type is a SafeArray and only occupies the 4 bytes used by the descriptor.

Answered 2021-Nov-02 at 21:42collect_list() gives you an array of values.
A. If you want to collect all the values of a column say c2, based on another column say c1, you can group by c1 and collect values of c2 using collect_list.
QUESTION
I've been using class modules for almost a year, and I'm just now comfortable with them. Now I'm trying to incorporate factory methods into data extraction from workbook tables. I found some great guides on the topic here, here, and here, but I'm unsure where to incorporate a collection of the class.
Up until now, I've setup my class modules with self-contained collections in this format:
