A class that returns different types of components
Stano replied to Stano's topic in Algorithms, Data Structures and Class Design
I have several events that are identical in content. I only use a different component there every time. In the example, I have dbmlmnsrMultiMonth. And I want to use this event for other components that do the same thing. Only with another dbxxx. . So now I have 10 x SpineditxxxChange. And I want a single SpineditxxxChange event! Every time I need to get the right dbxxx component there. -
I'm just guessing that instead of Sum () you want to have the product AAA.QTY * AAA-1.QTY

Well thank you. I was hoping to do it with some trick. -

procedure TfrmPlannerRole.advsedDayScaleChange(Sender: TObject); var SpinEdit: TAdvSpinEdit; begin SpinEdit := TAdvSpinEdit(Sender); MyClass.DBSource(5).Top := SpinEdit.Value; // TPanel end; procedure TfrmPlannerRole.advsedDayScaleChange(Sender: TObject); var SpinEdit: TAdvSpinEdit; begin SpinEdit := TAdvSpinEdit(Sender); MyClass.DBSource(3).Value := SpinEdit.Value; // TSpinEdit end; Perhaps the examples will explain. -

Stano replied to Stano's topic in Algorithms, Data Structures and Class Design
I'm aware of that. Even that it always has to be only one kind / type! That's why I used the term "components" to indicate what I really want. It should always be returned to a different type. -
I use a desktop with or without an MMX display. Quite often, MMX is displayed even if it is not to be. First image is OK, second is wrong. Win10 64, D 10.4.1

MMX window will appear in Design when using the "Copy Selected Component`s name fo Clipboard" button.

1 error + 1 error = 3 errors? where is the extra one?
Stano replied to c0d3r's topic in Delphi IDE and APIs
Compilers generally try very hard if they find a bug. Then they don't know when to stop. D10.4 has made significant progress in this direction. The number of reported errors is several orders of magnitude lower. Even so, it is recommended to believe only the first mistake and ignore the others. I wouldn't make it a science. -
Could you give it a rest with the formatting? Your posts are hard enough to tolerate without it. Highlighting important parts is fine. Even pictures! But using a large font for almost the whole topic is no longer okay.

I assume that reference integrity is defined in the DB. I think AV is the wrong term used. Each correct DB raises an exception, not an AV, in the event of an integrity violation, which must be handled. I know two basic ways to deal with emptying tables. 1. Empty tables from the lowest level to the next. In terms of referential integrity 2. Use DeleteCascade when defining reference integrity.

Customizing source editor

For what? I use one scheme. -
I am convinced that tbl1660.Active: = true; and company is completely useless. If you need to update the table, use Refresh. But not where Adocommand is

The rest of the user interface can also be customized. It's just more work. Background, font ... I remembered trying it. It didn't suit me. The dark theme suits me perfectly. My eyes don't complain. -

Um, the basic rule: always check the input arguments! This is from a wise book -

I used the Delphi IDE Theme Editor until they added a dark theme to Delphi. They allegedly implemented it in Delphi. Well thank you -

Yes. I can't get to that. It will help me decide whether to go for it. I don't see Gross Green anywhere. -

Green literally heals the eyes. Please take a screenshot and drop here. I don't know how to get to the Grass Green background. Well thank you. I saw the best color rendering in the black and white era. They were French monitors. The base was brown-yellow and the font yellow. It was a pleasure to look at them. -

Me too? I had in mind during the programming and in one place. -

They don't all show up at once -

Where is the published code from? Own? Probably not. Do you have experience with programming? If so, which ones? In any case, I very hard recommend you http://docwiki.embarcadero.com/Libraries/Sydney/en/Main_Page
