Linking to Delphi (API interface) Necessary files The following files are needed in order to link the DLL into Delphi programs: TcAdsDll.dll - dynamic function library

 https://infosys.beckhoff.com/english.php?content=../content/1033/tcsample_bdelphi/html/TcAdsDLL_COM_Delphi_Setup.htm&id=

 Linking to Delphi XE2 (COM interface)

The TcAdsDll.dll type library has to be imported (TcAdsDll_TLB.pas unit). Depending on the Delphi version, manual adjustments may be required in order to ensure error-free translation.
Requirements

    Delphi XE2;
    TwinCAT 2.9 or higher;
    TcAdsDll.dll - dynamic function library located in the Windows NT/2000 /XP/... 'System32' directory.

Import Type Library

1. Select Component -> Import component menu command. In dialog window select the option: Import type library and confirm with the Next button.

Title: Extracting Resource Data from an Exe
Question: Article 832 mentions how one can put Files into an Exe. This shows you how you can get it out
Answer:
I've written a simple function that does this for you, just cut and paste (some detail is below)

procedure ExtractToFile(Instance:THandle; ResID:Integer; ResType, FileName:String);
var
  ResStream: TResourceStream;
  FileStream: TFileStream;
begin
  try
    ResStream := TResourceStream.CreateFromID(Instance, ResID, pChar(ResType));
    try
      //if FileExists(FileName) then
        //DeleteFile(pChar(FileName));
      FileStream := TFileStream.Create(FileName, fmCreate);
      try
        FileStream.CopyFrom(ResStream, 0);
      finally
        FileStream.Free;
      end;
    finally
      ResStream.Free;
    end;
  except
    on E:Exception do
    begin
      DeleteFile(FileName);
      raise;
    end;
  end;
end;

Glassbutton updated to v2.4
3 Comments    

This is a long forgotten update to my rkGlassButton component. Some bugs have been corrected and it now work more as expected.

The first ting first. The autosize property is working like it should.
Secondly the down property also work when duostyle is active.
Last but not forgotten OnClick now work as expected.

Please report any bugs you find to me.

Hope this helps a little

A smarter button
8 Comments    

There is a lot of buttons out there I know but I have yet to find a button like this where you can have more than one button in “one button” (see screen shot). Especially at no cost.
RkSmartButton on display.

RkSmartButton on display.

I belive this is all you need to get started using rkSmartButton. I have tried to make it easy to use but there are a few things worth noticing… to show a popupmenu on any of the buttons you must set a flag in ButtonsPopup property which will look, something like this: 0010 “0” means do not show “1” means show. In this case only third button will get the popup. I also use this technic for enabling buttons and keeping hold of which one is down. No popup will be shown if CheckButtons is set. Popupmenu is shown after the button is pressed and hold down for the time given in PopupDelay property (like in Chrome). To get images on button add an imagelist and set the indexes in the ImageIndexes property. Use format like this: 0,1,2,7,4. To know which button was pressed use SelectedIndex property. Button number one gets the index of 0.

Thats it, hope you like it.

Next up is an update of SmartPathBar.

Изменить цвет TButton


{
  You cannot change the color of a standard TButton,
  since the windows button control always paints itself with the
  button color defined in the control panel.
  But you can derive derive a new component from TButton and handle
  the and drawing behaviour there.
