Unable to load project in Delphi 2007. Only one top level element is allowed in an XML document

CodeGear Delphi 2007
Loading the project .dproj file created in a newer Delphi that older Delphi 2007 version can cause such an error:
"Only one top level element is allowed in an XML document"

There is the requirement for XML document to have exactly one root element.
The error informs that ".dproj file" which is the document in XML format does not adhere to this requirement and thus malformed.
Perhaps, the .dproj file has been corrupted.

Unable to load project in Delphi 2007. Only one top level element is allowed in an XML document
The most expedient way to solve this issue is to remove the .dproj file, launch the correspondent .dpr file and let the IDE regenerate one.
If the matter is with dpk file, the way to solve is to create an empty package and import the files in.

FMSoft uniGUI components tryout

FMSoft uniGUI components version - Professional 1.90.0.1552 were tested in Embarcadero Delphi 11.3 Update 3 and Embarcadero Delphi 10.4.1 Update 1.

Embarcadero Delphi 11 Update 3

Argument out of range while using TuniDBGrid and TuniDBVerticalGrid

Two components: UniDBGrid (class TuniDBGrid) and UniDBVerticalGrid (class TuniDBVerticalGrid) showed erratic behavior in Embarcadero Delphi 11 environment. Both of them gave out error “Argument out of range” after placing om form. The mouse became trapped inside the form and it was difficult to release.

Several other components from some Categories: uniGUI Standard: UniCheckBox, UniGridPivotExcelExporter, UniStringGrid, UniFieldSet, UniFieldContainer, uniGUI Additional: UniBitBtn, UniDBEdit, uniGUI Data Controls: UniDBNumberEdit, UniDBMemo, UniDBHTMLMemo, UniDBNavigator, UniDBListBox, UniDBImage were tested and looks like they worked as expected.


Embarcadero Delphi 10.4 Update 1

FMSoft uniGUI standalone server working with TuniDBGrid and TuniDBVerticalGrid

Either UniDBGrid or UniDBVerticalGrid did not generate any errors and were workable in Embarcadero Delphi 10.4.1 environment.

An interesting fact: if the project is created, these components are placed on the form and everything is saved in the Delphi 10.4.1 environment, then these components and the project is workable if opened in Delphi 11.3.

ZEOS Library support for the Embarcadero Delphi 11, 12

Github logo
While testing the components made by FMSoft uniGUI with databases, I discovered that two versions of Delphi running simultaneously were fighting over Zeolib packages. So I had to make Zeolib support for Embarcadero Delphi 11.
This addition gives the support for Embarcadero Delphi 11 to ZeosLib, changed the LibSuffix from 270 to 280 for Delphi 11.
Published on Github

On November 14th I had to make Zeolib support for Embarcadero Delphi 12.
This addition based on Zeos 7.2.14 Release gives the support for Embarcadero Delphi 12 to ZeosLib, changed the LibSuffix from 280 to 290 for Delphi 12.
Compile for Windows 32 Target Platform.
Before my code edits, the Delphi 12 Athens compiler gave an error: "E2251 Ambiguous overloaded call to 'Max'"
Published on Github
ZeosLib is Database components for Delphi, FreePascal/Lazarus, Kylix, C++ Builder
I used ZEOS Library for development with SQLite.

HexEditor

HexEditor

Simple corrections brought in THexEditor, THexToCanvas by Valient Newman to make the component meet the requirements of Delphi 6 and higher, when the design-time and runtime code must be separated.

Checked in Delphi 7 and Delphi 2007

This component is used in Activity and Authentication Analyzer

The compoment HexEditor is available in My Github Repository

THexEditor v1.16, THexToCanvas v1.0 Beta 2

THexEditor descends from TCustomGrid, and displays and edits hexadecimal/binary files THexToCanvas is a descendant of TComponent, assign a THexEditor to it, set some properties and you can paint the hex data to a canvas (e.g. printer canvas)

What Delphi version matches Delphereum for the best

Delphereum Logo
Delphereum is a Delphi interface to the Ethereum, but one must choose proper Delphi version to compile projects in learning.

Unit scope names are prefixes that are prepended to unit names, this feature appeared in Delphi XE2 (VER230). Delpherium uses Unit scope names, for example, web3.eth.
That means Delphi version must be XE2 or higher.
Rudy Velthuis, one of the co-author, writes in comments section in the heads of units "Delphi version XE2 or later".

Well, but in unit web3.json.pas Stefan van As uses inline variable declarations, for instance,
var I := value.EstimatedByteSize;
such syntax appeared only in Delphi 10.3 Rio (VER330)!
Now I have a choice: either to update Delphi to a version higher than 10.2 Tokyo, or try to correct the sources using conditional compile directives, hiding variable declarations inside lines for versions 230-320 and assuming a role of co-author, needless to say if such activity does not require a serious alteration of the sources, which can lead to other errors.
I am newbie in Delphereum, but not newbie in programming, and I foresee the effect of editing someone's code when you are not good at a subject area.
First I will write to the author, Stefan van As, perhaps, his opinion will be useful or decisive.
unit web3.coincap;

In Delphi XE6 System.NetEncoding in Uses clause was not resolved.
In Delphi XE7 appeared.
Again
unit web3.coincap;

There was System.Types.IAsyncResult neither in Delphi XE6 nor in Delphi XE7.
Present in Delphi XE8, and is in Embarcadero Delphi 11 Alexandria for certain.
I decided to refuse from directive {$IFEND}, leaving the only {$ENDIF} and remove the conditional compilation directive {$LEGACYIFEND ON} at the beginning of the units. I only managed to spoil it with my edits in web3.json.
web3.json unit has copyright (c) 2018 of Stefan van As.
The directive {$ENDIF} was introduced in Delphi XE4, but versions earlier than Delphi X4 with {$IFEND} are out for Delpherium, because now I found out, that at least Delphi XE8 is to continue.
Delphi XE8 and THTTPClient
Delphi XE8 and unit web3.http
'THTTPClient' does not contain a member named 'BeginGet'...
'THTTPClient' does not contain a member named 'EndAsyncHttp'...
'THTTPClient' does not contain a member named 'StatusCode'...
In Delphi 10.2 Tokyo there appeared:
functions BeginGet, EndAsyncHTTP and property StatusCode
in THTTPClient, unit System.Net.HttpClientent.
But the Delphi 10.2 Tokyo compiler in gave out the next errors, unit web3.http:
E2250 There is no overloaded version of 'get' that can be called with these arguments
in function call
const response = get(URL, [TNetHeader.Create('Content-Type', 'application/json')], backoff);
Embarcadero Delphi 10.3 Rio brings inline variable declarations and now there is no need to insert compiler directives, where inline variable declarations were.
Units web3.http, web3.coincap, web3.json, web3.sync were replaced with original copies.
But the Delphi 10.3 failed to compile, reported two errors in unit web3.coincap:
[dcc32 Error] E2149 Class does not have a default property
in line:
Result := TAsset.Create(TJsonArray(FJsonValue)[Index]);
Class - TJSONArray.
and
[dcc32 Error] E2010 Incompatible types: 'IAsyncResult' and 'web3.IResult'
in
function assets(const callback: TProc, IError>): IAsyncResult;
Embarcadero Delphi 10.4 complied and launched the project Connecting Delphi to a local (in-memory) blockchain

Summing up!
Delphereum with the first example Connecting Delphi to a local (in-memory) blockchain was test in Embarcadero Delphi XE6, Delphi XE7, Delphi XE8, Delphi 10.2 Tokyo, Delphi 10.3 Rio, Delphi 10.4 Sydney, Delphi 11.3 Alexandria.
Delphereum can be compiled and run in Embarcadero Delphi 10.4 Sydney or Delphi 11.3 Alexandria environment.
I got an idea it is wrong for Delphereum to be without a logo and me proposed it.
P.S.
Thanks to my schoolkid son for giving me his old computer for testing.

Made the github repositories for source code examples for Ethereum for Delphi Developers (Ethereum programming on Embarcadero Technologies Delphi). All of this was possible due to tutorials of Stefan van As

Web3, Decentralized autonomous organizations, Identity, Ethereum address

Ethereum Logo
Web3 solves these problems by allowing you to control your digital identity with an Ethereum address and ENS profile. Using an Ethereum address provides a single login across platforms that is secure, censorship-resistant, and anonymous.
Quote was taken from Introduction to Web3. ethereum.org
I am tormented by seditious thought: the use of a unique and single address of that Ethereum is not the same "Permanent record", utmost centralization, the authentication token, but created and presented by the very man and by his own will?
Zero-knowledge proofs, however, can simplify authentication for both platforms and users. Once a ZK-proof has been generated using public inputs (e.g., data attesting to the user's membership of the platform) and private inputs (e.g., the user's details), the user can simply present it to authenticate their identity when they need to access the service. This improves the experience for users and frees organizations from the need to store huge amounts of user information.

No metadata could be loaded for: BlackfishSQL

Database Explore
Description of the problem is given for Delphi 2007.
Window of "Database Explore"
No metadata could be loaded for: BlackfishSQL
While an attempt to launch the "SQL Window" the Message box with error appeared.

Now is the solution:
While the RAD installation "dataexplore.exe.config" file is stored into the path:
"C:\Users\All Users\{6AF0EFC6-B937-4704-A430-319EB93F4C12}\dbexplr\D3C32C11\E7AAAB64..."
The way with aliases is:
"C:\Documents and Settings\All Users\Application Data..."
The "Database Explore" [dataexplore.exe] turns to the contents of the "Config file" [DataExplore.exe.config] which is in the "C:\Program Files\CodeGear\RAD Studio\5.0\bin" path.
The problem is solved by coping the "Config file" from the directory with "All users" path to the "bin" one!

F1026 File not found: 'DockForm.dcu'

CodeGear Delphi 2007
Migrating to Delphi 2005/2006/2007/2009/2010 and higher ussues.
There is no DockForm.pas in Delphi 2005/2006/2007/2009/2010 sources but you can use it in your application.
DockForm with such a name appeared in Delphi 4/5, with name uDockForm was in Delphi 6/7.
This is a piece of humpbacked advice:
Just add "designide" in Project -> Options -> Packages -> Build with runtime packages.
The design time package with the code in it is needed, add to "require" section.
Such an advice is applied for research only purposes.
First: to run the application on a computer where Delphi is not installed, one will need the copy bpl-file is required.
Second: it is not allowed to deploy any of that code, copyright would be infringed. One should never be recompiling the code in the toolsapi source directory.

Where is Proxies.dcu? Cannot find unit Proxies.pas

Delphi 6 About Dialog
While migrating to new versions, Delphi may lack the Proxies file.
This is a common issue while porting components.
If application or expert uses designtime information in Delphi 6 and later, one have to replace
uses DsgnIntf;
with
uses DesignIntf, DesignEditors;
But then one can run into an error message 'Cannot find unit Proxies.pas'
If this occures in a run-time package then one should separate out the design-time items and put them into a design-time package.
Humpbacked advice: one should then add DesignIde.dcp to the requires section of your design-time package.
Such an advice is applied for research only purposes.
To run the application on a computer where Delphi is not installed, one will need to copy bpl-file.
One are not allowed to deploy any of that code.

Footnotes

CodeGear Delphi 2007
  1. All this information relates to the native Delphi compiler, not the .NET compiler.
  2. From Delphi XE5 the use of the {$IFEND} directive results in a compiler error unless a {$LEGACYIFEND} directive precedes the first {$IFEND} directive or unless the use of legacy {$IFEND} is enabled in project options.
  3. Source: EFG's Computer Lab (defunct website). This source also stated that the Math unit did not change from Delphi 4 to Delphi 5.


Embarcadero Delphi 10.4 does not support Windows 7. Delphi 10.3 still does.
RAD Studio 12 offers official support for iOS 17 (for Delphi only), Android 14, and macOS Sonoma. RAD Studio 12 also supports Ubuntu 22 LTS and Windows Server 2022.

CodeGear Delphi 2007 for Win32: F2039 Could not create output file

CodeGear Delphi 2007
While installing RX Components Library the next
"[Pascal Fatal Error] rxctl.dpk(111): F2039 Could not create output file 'C:\Program Files (x86)\CodeGear\RAD Studio\5.0\RX\packages\Delphi2007\rxctl.drc'"
message appeared.
The problem solved by giving "Full access" to "Users" to the needed
"C:\Program Files (x86)\CodeGear\RAD Studio\5.0\RX\"
directory.

The similar error appeared in Embarcadero Delphi 11 Alexandria. The solution is also the same.

CodeGear Delphi 2007 for Win32: F2039 Could not create output file
Embarcadero, RAD Studio Reference, gives the similar recommendation:
F2039 Could not create output file '%s' (Delphi)

Borland.Delphi.Targets was not found

Applied to Delphi 2007/2009, Windows 8.1/10/11
Borland.Delphi.Targets was not found
Error
Unable to load project ... .dproj The imported project "C:\Windows\ Microsoft.NET \F…\Borland.Delphi.Targets" was not found. Confirm that the path in the declaration is correct, and that the file exists on disk.
... .dproj
There are a lot of topics in the Internet containing the error message
The imported project "C:\Windows\Microsoft.NET\Framework64\v2.0.50727\Borland. Delphi.Targets" was not found. Confirm that the path in the <Import> declaration is correct, and that the file exists on disk.
RAD keeps the copies of Targets files in the
"C:\ProgramData\{B59CE2E6-B15A-4F23-BD0E-72BF2ADDC3C7}\core\7EFD2DA3\6C948720\"
directory, and they can be copied to
"C:\Windows\Microsoft.NET\Framework\v2.0.50727\"
("C:\Windows\Microsoft.NET\Framework64\v2.0.50727\") /
sometimes to
"C:\Windows\Microsoft.NET\Framework\v4.0.30319"
("C:\Windows\Microsoft.NET\Framework64\v4.0.30319")
if absent.

But error can still exist!
The matter to give "Full control" to "ALL APPLICATION PACKAGES" ("Все пакеты приложений") for the "C:\Windows\Microsoft.NET\" directory.


Note:
"ALL APPLICATION PACKAGES" ("Все пакеты приложений"), appeared with WIN 8.
SID - ALL_APP_PACKAGES
The All Application Packages group is a well-known group with a predefined SID. The group must have specific access to certain locations of the registry and file system for Microsoft Store Apps to function properly.

There is a more clumsy way to fix this error.
Find the line <Import Project="$(MSBuildBinPath)\Borland.Delphi.Targets" /> in project file .dproj. This line is located about at the end of file.
Replace the value "$(MSBuildBinPath)\Borland.Delphi.Targets" with full path to file, for instance: "C:\Windows\Microsoft.NET\Framework\v2.0.50727\Borland.Delphi.Targets"
