hello Mr Long. I'm currently busy with a program that requires "if" statements, however every time I want to use the if statement it gives me an error and says "Type of expression must be a BOOLEAN expression". Can you perhaps help me please?
@@MrLongITandCAT Hi again, I sort it by myself, I forgot the brackets () thanks again. I do have another question about my database, when I want to reach data in my database and use the table name like tblCD it says undeclared identifier, please help
Hi,I started IT school this year, was finally implemented into my school so very happy about,but I realized you did not tab,Our teacher said tabbing is a must,so is it ?
Tabbing or indenting your code makes a big difference especially when you are looking a large sections of code and trying to figure out which parts are associated with which sections and where begins and ends match. In other programming languages, indenting is part of the logic (in other words, an indent line works differently if it was not indented because of the line above it, etc). So learning to indent your code is a very good skill and style to practice in Delphi.
You have no idea how big you’re helping me for my practical tomorrow 😭

Can you copy the IF statement into the comment so I can see what it looks like.

@@damion4369 Are you using a data module or are your connection components in the same form as your code.
When do I need variables? (im a complete newbie) I can't quite figure it out.
The next video in the series explains examples of when and how to use variables. Here is the link: th-cam.com/video/T7kkQLEk_m4/w-d-xo.html
You saved my life, Thank you, you got yourself another subscriber
