unoconv (Universal Office Converter) Windows build

August 15, 2020 | PDF Software | No Comments

Universal Office Converter (unoconv) is an open-source command-line tool to convert any document format that LibreOffice can import to any document format that LibreOffice can export. It makes use of the LibreOffice’s UNO bindings for non-interactive conversion of documents. The project has no Windows package download, We build a native Windows exe and bundled LibreOffice […]

Delphi 5 TDateTimePicker Format

April 9, 2019 | Delphi Programming | No Comments

During add Delphi 5 compatibility to the Purchase Order calculation sample of HotXLS Delphi Excel Spreadsheet component, an error occurred while compiling under Delphi 5. The line which set the date format of the TDateTimePicker control does not compile:

DateTimePicker.Format := 'MM/dd/yyyy';

ftol and the 64bit Delphi inline asm changes

April 9, 2019 | Delphi Programming | No Comments

function _ftol( f: double) : Integer; cdecl;
begin
  asm
    lea    eax, f
    fstp  qword ptr [eax]
  end;
  result := Trunc(f);
end;

function _ftol( f: double) : Integer; cdecl;

begin

asm

lea eax, f

fstp qword ptr [eax]

end;

result := Trunc(f);

end;

Above is a Delphi inline asm version of the ftol (Floating Point to Integer Conversion) function used by our HotPDF Delphi PDF component. When compiling above Delphi codes in the 64-bit target platform, Delphi will raise below error: [dcc64 Error] E1025 Unsupported language feature: ‘ASM’ The reason is: The 64-bit Delphi compiler DCC64 does […]

Delphi Incompatible type tagLOGBRUSH tagLOGBRUSH32

March 8, 2019 | Delphi Programming | No Comments

When using Delphi XE2 or above editions to compile coeds likes below:

procedure VEMRCREATEBRUSHINDIRECT(Data: PEMRCreateBrushIndirect);
begin
  GDIObjects[Data^.ihBrush] := CreateBrushIndirect(Data^.lb);
//GDIObjects and CreateBrushIndirect are defined in the winapi.windows unit.
end;

procedure VEMRCREATEBRUSHINDIRECT(Data: PEMRCreateBrushIndirect);

begin

GDIObjects[Data^.ihBrush] := CreateBrushIndirect(Data^.lb);

//GDIObjects and CreateBrushIndirect are defined in the winapi.windows unit.

end;

The compiler says: E2010 Incompatible types: ‘tagLOGBRUSH’ and ‘tagLOGBRUSH32’. The solution to fix this compiling error is:

procedure VEMRCREATEBRUSHINDIRECT(Data: PEMRCreateBrushIndirect);
var
  LogBrush: TLogBrush;
begin
  LogBrush.lbStyle := Data^.lb.lbStyle;
  LogBrush.lbColor := Data^.lb.lbColor;
  LogBrush.lbHatch := Data^.lb.lbHatch;
  GDIObjects[Data^.ihBrush] := CreateBrushIndirect(LogBrush);
end;

procedure VEMRCREATEBRUSHINDIRECT(Data: PEMRCreateBrushIndirect);

var

LogBrush: TLogBrush;

begin

LogBrush.lbStyle := Data^.lb.lbStyle;

LogBrush.lbColor := Data^.lb.lbColor;

LogBrush.lbHatch := Data^.lb.lbHatch;

GDIObjects[Data^.ihBrush] := CreateBrushIndirect(LogBrush);

end;

C++Builder dynamic create & delete HotPDF component instance

February 22, 2019 | PDF Software | No Comments

This example shows you how to programmatically New and Free a HotPDF object instance with C++Builder.

#include 
#pragma hdrstop

#include "Unit1.h"
#pragma package(smart_init)
#pragma link "HPDFDoc"
#pragma resource "*.dfm"
TForm1 *Form1;

__fastcall TForm1::TForm1(TComponent* Owner)
    : TForm(Owner)
{
}

void __fastcall TForm1::Button1Click(TObject *Sender)
{

    THotPDF* HotPDF1 = new THotPDF(this);
    HotPDF1->FileName = "HelloWorld.pdf";
    HotPDF1->AutoLaunch = true;      
    HotPDF1->BeginDoc(false);
    HotPDF1->CurrentPage->PrintText( 10, 10, 0, "Hello World!" );
    HotPDF1->EndDoc();
    HotPDF1->Free(); 	
}

#include

#pragma hdrstop

#include "Unit1.h"

#pragma package(smart_init)

#pragma link "HPDFDoc"

#pragma resource "*.dfm"

TForm1 *Form1;

__fastcall TForm1::TForm1(TComponent* Owner)

: TForm(Owner)

{

}

void __fastcall TForm1::Button1Click(TObject *Sender)

{

THotPDF* HotPDF1 = new THotPDF(this);

HotPDF1->FileName = "HelloWorld.pdf";

HotPDF1->AutoLaunch = true;

HotPDF1->BeginDoc(false);

HotPDF1->CurrentPage->PrintText( 10, 10, 0, "Hello World!" );

HotPDF1->EndDoc();

HotPDF1->Free();

}

You need to set the include & library path of the project to the directory where HotPDF library files exist.
