Yes, CDB is correct with how to write the key to the Registry. When the trial period is over you can show a form stating such and have a text field where they can enter the key that you provided them (one of the ones in your IF STATEMENT). Once they enter the key you can then use CDB's WriteString statement to store it in the Registry. From that point on your program will read the Regisrtry key and since it is one of the ones in your IF Statement, your program will allow your user to continue using your software. Hope this makes sense.

Frank,
If you are using JB's script, then you should see your app name under the SOFTWARE folder in the Registry. Click on your app name and the registry entries for your app will be in the right side panel. Right-Click on each entry and select DELETE. It's ok to delete your own entries since your app should be rewriting them. You definitely do not want to mess with any other software entries, so be sure you are on your own app entry.

salahnecibi,
Not exactly sure what you are trying to do. It sounds like you are trying to import html code right into FastReport. I don't think you can do that. FastReport does allow some simple HTML tags in text objects. Look in the FastReport manual Chapter 2.4 (Page 19) for more information on that.

FastReport is robust enough for formatting that you do not need html tags for formatting, if that is what you are trying to do.

Try this

const
  APP_NAME = 'My App Name';
procedure Form1_OnShow (Sender: string; Action: string);
begin
  Form1.Caption := '';
  if FindWindow(nil, APP_NAME) <> 0 then
  begin
      ShowMessage('This application is already opened, you cannot open it again.".');
      Form1.Close;
  end;
  Form1.Caption := APP_NAME;
end;

I am not sure what you mean by

bbrother,
See attached for a solution to your report. Select a record on the Form1 grid and click on NEW REPORT button.

Keep in mind that most all of us on the forum are volunteers and contributes whenever they can. Sometimes it may be a few days before somebody can respond. Personally I'm lucky if I can get on here once a week. I have my own clients to take care of and they come before this forum. So try to be a little patient. You'll get your answers from somebody.

bbrother,
Welcome to MVD. There is a sum function in Fast Report to sum various columns in the detail bands of a report. If you could upload your project, it would be easier for people on this forum to provide solutions for you.

anils,
Welcome to MVD.
The syntax of calculated fields is SQL. So you can use available references outside of MVD. On occasion there can be subtle differences between Sqlite and MySql. So depending on the database you are using you may need to adjust the SQL syntax for the appropriate database. But this is only in rare occasions.

unforgettable,
See attached for print.

There are a bunch of sites for SQL. Here is one of many for learning: https://www.w3schools.com/sql/default.asp.

Frank,
Typically an object on a form has three parts to it. The form name that the object belongs to, the object (field name), and the property of the object. So it usually looks like this: formname.fieldname.property. An example is Form1.Edit1.Text

Therefore your If statement should be:

if frmHousing.cboRentOwn.Text = "Own" then
        frmHousing.hPurchaseDate.Visible := True else frmHousing.hPurchaseDate.Visible := False; 

jopowers68,
What you want to develop can be done by MVD. However, DriveSoft is not in the business of developing end user apps. They are the creators of MVD for us end user developers. I don't see anything in your scope that seems out of the ordinary, but it's up to you to put together the application. Maybe someone on this forum can either help you or maybe for a fee could develop it for you, if you do not want to take it on yourself.

As far as a chart on a report, here is an example of doing that.  FYI - The chart can be most any style, bar, pie, line, gannt, etc. 3D or flat, etc.
