I hope that this is going to work the same for C++ (I am doing it in Delphi):

1.) Open the file, select View as Text (Alt + F12)

2.) Do a search and replace

3.) go back to View as Form (alt + F12)

4,) save the file.

During the saving process the IDE should ask to replace the definition. This the Delphi way

Plan b. do the search & replace using refind.exe - https://docwiki.embarcadero.com/RADStudio/Alexandria/en/ReFind.exe,_the_Search_and_Replace_Utility_Using_Perl_RegEx_Expressions in case you have multiple forms.

Are there scenarios where designing in HighDPI would be beneficial? Just to improve the development experience or to improve the user's experience when using the produced app?

An example would be Quick Report. It was designed to work only with 96PPI. When HighDPI is not allowed for the application the generated preview would be wrongly scaled and would not fit the page.

As for AI and privacy - keep your secret credentials separated from your code.  Other than that, I don't think that many of us write code that truly needs to be hidden for secrecy reasons, although it is obvious that it will be necessary to ensure that privacy permeates the use of AI.

It is not about privacy. it is copyright. Anyone that has invested money into an algorithm and solution would not like to see it to appear inside an AI suggested code. That is one of the reasons why the source code for Microsoft Office is not open sourced.....

I don't think you can use the XE5 if you have bought XE3. You must discharge it but probably the license will not be activated during installation.

You can install XE5 only if you have had support for XE3 at the time when it was released otherwise no. You can try with your XE3 serial number to activate.

You don't believe in AI?

I am with the idea that was presented in the Delphi's birthday webinar, I do not want the code from any of the projects I am working on to land in some AI database and pop up as a suggestion on a query. The code I am working on belongs to the company I am working for or a client. Nobody wants that code to go public.

I am ok with the idea and did it a couple of times to ask Bing to write some simple code that I can review faster than to type in, have some fun. 

First step is to exclude the folder for a project that antivirus program reports and upload the generated exe to VirusTotal. If it is a false positive the next step is to report it to your antivirus program as false positive.

Edit. So far, I have done this twice. Last time, a couple of years ago Microsoft Defender started to mark the Delphi executables as virus infected. After I filled the report, the issue was gone in 5-7 days. The other time when I did it was more than a decade ago.

Close the Local variables, it's that slow at least since Delphi XE5.

You should backup the installation ISO for every Delphi  you use before you let the subscription expire. Also it could be problem to bump up the registration limit if you don't have an active subscription - a solution could be to install Delphi to a virtual machine.

This was changed in D12, in Delphi 11 it was declared as:

const
  {$EXTERNALSYM CW_USEDEFAULT}
  CW_USEDEFAULT = DWORD($80000000);

now it's:

const
  {$EXTERNALSYM CW_USEDEFAULT}
  CW_USEDEFAULT = Integer($80000000);
 

I don't read that way. The remark is:

Note: To avoid ambiguity, conversions must be explicit, as the following code example illustrates.

In the example MyList.delete(0) I don't see ambiguity. The examples on that page are reather bad.

I understand from the link above that who installed with old online installer GetIt will not work.

"Customers who have installed RAD Studio 12 using the online installation process won’t have the ability to add new platforms and core features to the product via the Manage Features dialog. In order to do this, they will need to uninstall and then reinstall using the new inline release."

It's not about the GetIt or Welcome page.

For D12 there is a new installer because GetIt server changed.

I suppose you need to install with the new installer in order to work Welcome page or Tools menu.

That's not possible. The Welcome page is working fine for me (installed from the ISO image). I doubt that the ISO and online installer has different setup for the GetIt.

You have not posted a link and probably it's a stupid question but how to find a RSP by number?

1.) Log into https://quality.embarcadero.com/

2.) Enter RSP-26436 into search (you can find it at the upper right corner of the page) and you cannot copy paste it from the text above as it contains unicode characters.

Nothing else has changed.  It is repeatable.

Is it me or is there a bug un the Patch/update?

It didn't happen before the Patch/Update.

Unfortunately the parser that the IDE uses is not up to date. I also have some cases where the editor messes up my code I have to pay attention what I am doing. In one class I can add a property only if I paste it from the clipboard entering using the keyboard is not possible.

Embarcadero might replace the IDE in near future (5-10 years from now).

Interesting I've the patch installed but the IDE thinks it's not installed......

This is a patch, not an update it should only change the Version.

(In case of Delphi 12 patch 1 (it's not officially 12.1) a clean all was required before I could compile a project group. I have tried before to uninstall design time packages that was not enough to remove the Access Violation when I tried to compile. After clean all I was able to compile.)

I think I've never seen this error. Debug version builds just fine.

In that case you was lucky or you are not using packages often. This error can appear at no reason, you have to recompile the packages and everything should work fine.

I'd like to ask here if D12 can be installed (with Android dev platform) on Windows 7 machine ? If yes, then 2nd part of my story is below.

 

Since a long time Windows 10 is reuqired to install the Delphi IDE. You can compile applications for older versions of Windows but the dev. machine should be at least Windows 10.  I am not aware if there a possibility to install it on Windows 7.

@Lajos Juhász  This solution is only possible when 32 bit drivers are available

There should be 32 bit clients for every database server. I doubt that every application that is connecting to database has moved to 64 bit.

You should be able to do so. I've done for Informix. At design time I use the 32bit ODBC driver while when compiled as 64 bit application runtime the 64bit driver.

How to Solve if any of the ListBox Items does not contain even first char of EditBox , ListBox items should not get clear , ListBox items must remain as it is because search criteria does not match any of the ListBox item.

procedure TForm1.Edit1Change(Sender: TObject);
Var
  i: Integer;
  lFilteredList: TStringList;
Begin
  lFilteredList:=TStringList.create;
  try  
    if trim(Edit1.text)<>'' then
    begin
      for i := 0 to list_global.Count - 1 do
        if pos(Edit1.text, list_global[i]) > 0 then 
          lFilteredList.Add(list_global[i]);
    end;
    if lFilteredList.count=0 then
      listbox1.items.assign(list_global)
    else
      listbox1.items.Assign(lFilteredList);     
  finally
    lFilteredList.Free;
  end;
End;

procedure TForm1.Edit1Change(Sender: TObject);
Var
  i: Integer;
Begin
  listBox1.Clear;

  if trim(Edit1.text)='' then
    listbox1.items.Assign(list_global)
  else
  begin
    for i := 0 to list_global.Count - 1 do 
      if pos(Edit1.text, list_global[i]) > 0 then 
        listBox1.Items.Add(list_global[i]);
  end; 
End;

In my opinion, the question belongs to TMS
https://support.tmssoftware.com/categories

It is a general algorithm. For search you loop to the items. While for search you have to maintain the data in order to insert into the components the values that match the criteria.
