I have an application that will load a CSV file containing two columns. At program load I need to have the first column as items in a combo edit control. Once the user selects (or enters a value) I need to populate a label with the value from the second column. My thought was to use an in memory data set, FDMemTable which would be loaded at form create. Then once the user selects, or enters an item, I would run a query to pull the description. I've tried but have been unsuccessful with the simple loading of the combo edit.
Is this the best way to achieve the desired results, and is there samples similar to what I'm looking to do?
Read the file.
Parse it into an array of name/value pairs.
Populate the combo drop down list with the names.
When the combo's selection is changed to a new index, read the value from the array using that index. Update the label.
Database tables and queries seem somewhat over the top for a single simple task like this.

I am currently a college student who was trying to make a dynamic google sheet where my data is organized. The premise is as follows:
I input raw data into one spread sheet titled "Raw Data"
That data from raw data is automatically sorted by date using the SORT function to keep it dynamically updated.
If an item in the organized data is checked, then the row turns gray and updates into a corresponding chart.
My problem is that as I add or edit data, the checkbox is stuck to the row. In the first picture, you see the normal data as is.

However, lets say I add a due date for an assignment on 1/31/23. Then this happens.
Spreadsheet data following SORT function modified to show problem
So overall, my question is how can I lock a checkbox to a specific row so if the row is moved, the checkbox moves with it? If it is needed, I have a public link to the spreadsheet if it helps understand the problem:
Public Spreadsheet 1/31 for Clarification
I currently tried several data validation rules but most of them simply locked the cell from being edited if it was checked.
I also tried modifying the RAW data and adding a checkbox there before the sort function refreshes but that negates the point of the sheet at all then.
I was not sure how else to go about it trying to lock it into that place. Also, I was not sure how to upload as a MARKDOWN text table so I figured an image would suffice for the problem.
I am creating a tool for a video game I play.
Link to the example spreadsheet (Please make a copy to edit so that this copy stays intact for additional helpers).
Sheet 1 is “Choose Owned”. It contains a list of all of the champions available in the game and includes their attributes.
Column A contains checkboxes. Checking a checkbox indicates that the user owns that champion, and brings it to Sheet 2.
Sheet 2 is called “Owned”. It contains a list of the champions checked off in “Choose Owned” (aka the champions the user owns). “Owned” includes the champion attributes too, as first seen in “Choose Owned”.
Beyond those same attributes, “Owned” contains 8 additional columns.
These columns are from Columns G:N and are labeled ‘Level’, ‘Rank’,
‘Ascension Lvl’, and ‘Team Label(s)’ (‘Team Label(s)’ takes up
columns J:N). This data is all unique information and requires the
user to input the information themselves depending on their
champions.
Because there are so many champions, I want the user to be able to use the Filter function in “Owned” so they can easily locate the champion they need or sort the table however they wish.
However, because I use the QUERY function to get the data from “Choose Owned”, the Filter function tends to break. The most obvious error comes when you try to sort A-Z or Z-A; this simply cannot be done. I was fine with this, and have even included a note at the top telling the user to avoid sorting alphabetically.
Everything else works correctly until the user tries to add a new champion from “Choose Owned”. When the champion is added to “Owned”, the additional, unique data in columns G:N go out of order because they don’t move with their original champions.
Example:
I choose my champions. These champions are copied to “Owned”.
I pick their relative data in columns G:N.
A few days later, I obtain new champions and check them off in “Choose Owned” so they are added to “Owned”. However, when I do this, the champions stay in the same order as they are in “Choose Owned”, and columns G:N do not move with their champions so now, that information is with the wrong champion.
I want the additional data (G:N) to move with their champions when the table is edited due to champions being added. Or, in other words, I want those columns to stay linked to the first columns.
If there is a different way to achieve all of this like if I have to use a function other than QUERY, that is fine!
Please share any solutions you may have. I would prefer to not use a script but will consider the idea if it works.
this is a common issue within Google Sheets and it's solvable in 2 ways:
either by introducing a common value (unique ID) and then linking the manual input to query and aligning it by ID
or easier approach in your case - using timestamp/linear ID so every new entry would be added to the bottom and then the query would be sorted based on this order.
I want to fill a Repeated grid with value from a checkbox.
User would select multiple items from a checkbox then hit a button to add the required number of rows and set the value of a field in each iteration according to what was checked
I would need something like a foreach checked value : run this code
I'm having a hard time finding documentation about this kind of Xforms. I did find some info about Iterate and Iterator that seems promising but i failed to make that work.
I was able to add the required number of row to my grid but then im not sure how to use xf:setvalue set the value of each row.
Any help appreciated.
I think a combination of the iterate attribute to create a loop, the xxf:split() function to get the selected values as a sequence you can iterate on, and xf:insert to create elements will do the trick. See this example, which does the following:
And here is an example which does the same, but for a form created with Form Builder. In this case, the result is as follows:
So ATM the user can download an xlsx document, and add new records to it, upload it to the application which updates the DB(with the new records)
I would like to put an option in the excel doc. like a check box (at the beginning of each row) or something like this which, if selected when the doc is uploaded again, it will delete that record from the DB.
I know the logic and how to delete the record but im not sure how to include something like a check box and relate it to each seperate row?
Any one have any ideas?
thank ye
You can use Checkboxes, although you would need to use an "xlsm" (macro-enabled workbook) to insert them. (you could do it without vba but manually inserting checkboxes and configuring them isnt going to be much fun)
Checkboxes can be "linked" to a cell in your workbook. You'd need to add a Checkbox to each line, and set the linked cell to another cell on that row (preferably all the same column).
You could also make it a lot simpler by doing away with the checkbox and just having a column that you set to true (or any non-empty value) and have your application interpret that to delete the records.
Both methods require you to have an extra column.
Any method will require either an extra column or another sheet with a single column to track the state of each line.
So I'm messing around with a new project in Delphi 2009 and the default components that can be dropped onto a form for accessing data consist of a SQLConnection, DataSource and SQLQuery. If I add a simple select to the query component, say:
select name from customers
and then drop a DBComboBox on the form and link it up with the DataSource I get a single record in the combo box. After using Google for half and hour to figure out what I was doing wrong it looks like you have to manually add some code to your project which loops through the dataset and adds all the records to the drop down box. Something like:
while not SQLQuery.eof do
begin
DBComboBox.items.add(SQLQuery.fieldbyname('name').asstring);
SQLQuery.next;
end;
And that actually sort of works, but then you get a list in the drop down which you can't actually select anything from. Regardless of the result though I'm wondering why would you even use a DBComboBox if you have to manually add the result of your query to it? Seems to me that if it doesn't automatically populate the db combo box with the result of the query then we might as well be using a non-data-aware component like tcombobox.
I guess what I'm asking is why does it work this way? Isn't the purpose of data aware drag-and-drop controls to minimize the amount of actual written code and speed development? Is there a method that I'm missing that is supposed to make this easier?
A TDBComboBox doesn't get its list of values from the database; it gets its current value from the database. Link it to a field in your dataset, and when you change the active record, the combo box's current value will change. Change the combo box's current value, and the corresponding field's value will change.
If you want to get the list of values from the database as well, then use a TDBLookupComboBox.
This is all covered in the help:
Using TDBListBox and TDBComboBox
Displaying and Editing Data in Lookup List and Combo Boxes
Defining a Lookup List Column
I think you want the TDBLookupComboBox because that allows you to lookup from a list of items where the list comes from a dataset.
In the TDBComboBox, the list is just a TStrings manually filled with data.
