    My main concern with a database approach is the unknown and variable number of fields. I'm not sure how to design the database structure to accommodate this and still allow for easy comparison between different snapshots. Could you elaborate on how you envision structuring the database to handle this dynamic nature and facilitate efficient comparisons?

    Your record structure would have a lot of string fields, one for each possible type of data you want to save; it'd also have a DateTime field so you could record when the snapshot of your system was taken. The key is to be consistent in how you store the data; for example, the network adapter information should always be stored in the same field(s) requiring some way of identifying them (or lumping all network adapters in one big memo field, perhaps). I'd probably create a detail table for some fields, like the storage section in your screen-shot above. You could have a field for GUID to identify each disk and then the main table would have a summary of how many disks and the total GB.

     

    You could use something like Mitec System Information components to scan your computer every time it booted up and if something changed, add an entry to your database with a new date/time stamp. Later, you could go through and see various changes over time as you scan the records. You could also filter on certain fields to see when something changed. 

     

    It's really important that you evaluate what and how often your data will change and what you want to do with it later. If this is a product you're building for others, definitely store it in a database; if it's just a one-time information gathering tool for your self over the next six months as your play around with different hardware configurations, just manually enter stuff into a spreadsheet. It really depends on your usage requirements and how much time you have.

    You asked this last May. Are you looking for a different kind of answer or new responses or just refreshing the question since this technology is so new and moving so fast?

     

    I don't use AI very often but Claude is the one I signed up for and like it.  It helps jump-start Delphi coding in some cases; but it's really great at building HTML pages for web projects integrated with a Delphi web server.

    If I select the default property, it disappears.

    I think what you might be seeing is standard behavior of the IDE saving property values. If the property has a default value, and that's the current setting of that property, it won't save to the DFM, it'll only save if it's different than the default or if there is no default.

     

    For example, a blank VCL application's Form might look initially like this: 

    object Form1: TForm1
  Left = 0
  Top = 0
  Caption = 'Form1'
  ClientHeight = 324
  ClientWidth = 401
  Color = clBtnFace
  Font.Charset = DEFAULT_CHARSET
  Font.Color = clWindowText
  Font.Height = -12
  Font.Name = 'Segoe UI'
  Font.Style = []
  TextHeight = 15
end

    If you check AlphaBlend, AutoScroll, and AutoSize in the Object Inspector, the DFM will look like this: 

    object Form1: TForm1
  Left = 0
  Top = 0
  Width = 417
  Height = 363
  AlphaBlend = True
  AutoScroll = True
  AutoSize = True
  Caption = 'Form1'
  Color = clBtnFace
  Font.Charset = DEFAULT_CHARSET
  Font.Color = clWindowText
  Font.Height = -12
  Font.Name = 'Segoe UI'
  Font.Style = []
  TextHeight = 15
end

    This has the three additional properties because they're no longer the default value.  If you uncheck them in the Object Inspector and save the form, it reverts back to the first one.

     

    Is this perhaps what you're seeing?

    We're just tidying up loose ends (like the installer) before beta - hopefully in a few weeks. 

    I bought a 3-year cert in Nov, 2022 so still have another year left on mine. But I'll definitely be looking at your offering.

    we have only tested using Yubikey and Safenet tokens

    I've got a couple of YubiKeys already--sounds great!

    Delphi 12.2 introduced a new text-processing engine, WebStencils, that can be used in WebBroker and other applications to generate HTML and other template-based text. To get my head around how to work with this, I wrote a couple of small WebBroker applications, one using PageProducers and the other doing the same thing using WebStencils. You can read about it in my latest blog entry, Introducing WebStencils and download the projects from Github.

     

    I hope this is useful for learning about this new text-processing engine.

    When I compile a program with 12.2 and deploy to a computer that has 12.1 bpls I get this error:

    I saw this yesterday as well for programs that were compiled with "Link with runtime packages" checked. The programs ran fine from the IDE but when I copied the .EXE out to a network share and tried to run it from there, I got the error. Not only did I need to recopy the BPLs from the newer version of Delphi, I also had to add two or three. After building the program, select Project > Information for <projname> and look through the list of packages that are used by that program.

    Is there any way to use the structure view to cause a tab on a ttabcontrol to become the active tab?

    Using the Structure Pane? No. The TTabControl and its tabs are one control, the tabs don't even show in the Structure Pane. The TTabControl is there for backwards compatibility; you should use TPageControl in new applications.

    To handle parameters built into the URL rather than as query parameters you'll need to do the following:

    Assign a partial path to the 'pathInfo' of your WebModule Action i.e.

    /getname/*

     

    Then, in your ActionHandler you'll want to access the path part of the URL, break it into an array split by / and then execute based on the parts that matter

    What would be the benefit to doing this extra work rather than letting WebBroker parse it for you into QueryFields?

    Do you know why there are many examples the use other options in the pathinfo property?

    Examples are:

    /getname/*                   {seen in some youtube videos}

    /getname/data/:id {thoughts are that id would be a parameter}

    I haven't used either of these in a WebBroker app but I think the asterisk will match any URI; for example, both /getname/list and /getname/edit.

     

    I don't remember seeing ":id" on the end of PathInfo in any examples; not sure what that's for.

    assigned an action pathinfo of /getname*

    The pathname should not contain the asterisk, just /getname

    how do I create parameters for values say parameters ssn and dob  would this become /getname/($ssn)/($dob)?

    You don't have to "create" the parameters, by simply accessing the URL with something like /getname?ssn=123456789&dob=19990531, the TWebActionItem parses out the URI and creates the parameters for you.  Then, you just access them in your event handler like this: 

    procedure TMyWebApp.ActionHandler(Sender: TObject; Request: TWebRequest; Response: TWebResponse; var Handled: Boolean);
var
  SSN: string;
  DOB: string;
begin
  if Request.QueryFields.Count >= 2 then
  begin
    SSN := Request.QueryFields.Values['ssn'];
    DOB := Request.QueryFields.Values['dob'];
    ...

    The "?" starts the beginning of the list of parameters; the "&" separates the parameters.

     

    On a side note, you should never pass private info this way (using the GET method on the URL); instead you should put them in a POST BODY. But that's a different topic.

    While I don't use CE and don't have an official answer for you, I would highly doubt this is possible--don't jeopardize your current installation!

     

    The CE FAQ doesn't answer this specific question but the fact that 1) it doesn't allow Delphi & C++Builder (only one or the other) and 2) doesn't allow CE and a paid version on the same machine, I'm almost positive it wouldn't allow two different CE versions to coexist. You could, however, install a virtual machine, and try it out there as it would be a completely separate environment.

    The one I recently purchased was this one: "Delphi Professional - Named - Support Renewal"

     

    But I do see there are others mentioned here on these forums: 

    * maintenance update -- 

    * update subscription - - 

    * support renewal -- the one I purchased. 

     

    Did I purchase the wrong one? 

    If you purchased "support" I think you may have purchased the wrong thing. Support is for Embarcadero to help you with programming questions. I think what you wanted is "Update Subscription" or maybe even "Maintenance Update" if that actually updates from an old version (which I didn't think they offer anymore).

     

    You'll need to contact your sales rep and explain what you really wanted/need and ask for clarification of what you purchased; if it's not what you thought it was, I hope they'll let you change it to the subscription.
