Use Adobe Acrobat (PDF) Files in a Delphi Application
by Zarko Gajic
Updated September 29, 2017
Delphi supports the display of Adobe PDF files from within an application. As long as you've got Adobe Reader installed, your PC will automatically have the relevant ActiveX control you'll need to create a component you can drop into a Delphi form.
Difficulty: Easy
Time Required: 5 minutes
Here's How:
1.Start Delphi and select Component | Import ActiveX Control...
2.Look for the "Acrobat Control for ActiveX (Version x.x)" control and click Install.
3.Select the Component palette location into which the selected library will appear. Click Install.
4.Select a package where the new component must be installed or create a new package for the new
TPdf control.
5.Click OK.
6.Delphi will ask you whether you want to rebuild the modified/new package. Click Yes.
7.After the package is compiled, Delphi will show you a message saying that the new TPdf component was registered and already available as part of the VCL.
8.Close the package detail window, allowing Delphi to save the changes to it.
9.The component is now available in the ActiveX tab (if you didn't change this setting in step 4).
10.Drop the TPdf component onto a form and then select it.
11.Using the object inspector, set the src property to the name of an existing PDF file on your system. Now all you have to do is resize the component and read the PDF file from your Delphi application.
Tips:
The Adobe ActiveX control installs automatically when you install Adobe Reader.
Step 11 can be completed during runtime, so you can open and close files programmatically as well as resize the control.

TreeView 增加 CheckBox/RadioButton操作選項
Ex1:
procedure TForm1.FormCreate(Sender: TObject);
var dw:DWORD;
begin
dw := GetWindowLong(tvWorkStep.Handle, GWL_STYLE);
dw := dw or TVS_CHECKBOXES;
SetWindowLong(tvWorkStep.Handle, GWL_STYLE , dw);
end;
增加2個Function
function SetTreeViewNodeChecked(ATreeView: TTreeView; ATreeNode: TTreeNode;
Checked: Boolean): Boolean;
function GetTreeViewNodeChecked(ATreeView: TTreeView; ATreeNode: TTreeNode): Boolean;
function TForm1.SetTreeViewNodeChecked(ATreeView: TTreeView; ATreeNode: TTreeNode; Checked: Boolean): Boolean;
var
tvItem: TTVItem;
begin
tvItem.mask := TVIF_HANDLE or TVIF_STATE;
tvItem.hItem := ATreeNode.ItemId;
tvItem.stateMask := TVIS_STATEIMAGEMASK;
(*Image 1 in the tree-view check box image list is the
unchecked box. Image 2 is the checked box.*)
if Checked then
tvItem.state := IndexToStateImageMask(2)
else
tvItem.state := IndexToStateImageMask(1);
Result := TreeView_SetItem(ATreeView.Handle, tvItem);
end;
function TForm1.GetTreeViewNodeChecked(ATreeView: TTreeView; ATreeNode: TTreeNode): Boolean;
var
tvItem: TTVItem;
begin
// Prepare to receive the desired information.
tvItem.mask := TVIF_HANDLE or TVIF_STATE;
tvItem.hItem := ATreeNode.ItemId;
tvItem.stateMask := TVIS_STATEIMAGEMASK;
// Request the information.
TreeView_GetItem(ATreeView.Handle, tvItem);
// Return zero if it's not checked, or nonzero otherwise.
Result := Boolean((tvItem.state shr 12) - 1);

Winapi.ShellAPI.ShellExecute
uses
ShellAPI;
function ShellExecute(hWnd: HWND; Operation, FileName, Parameters, Directory: LPWSTR; ShowCmd: Integer): HINST; stdcall;
以下轉貼至:
https://msdn.microsoft.com/en-us/library/windows/desktop/bb762153(v=vs.85).aspx
ShellAPI;
function ShellExecute(hWnd: HWND; Operation, FileName, Parameters, Directory: LPWSTR; ShowCmd: Integer): HINST; stdcall;
以下轉貼至:
https://msdn.microsoft.com/en-us/library/windows/desktop/bb762153(v=vs.85).aspx
Performs an
operation on a specified file.
Syntax
HINSTANCE ShellExecute(
_In_opt_ HWND hwnd,
_In_opt_ LPCTSTR lpOperation,
_In_ LPCTSTR lpFile,
_In_opt_ LPCTSTR lpParameters,
_In_opt_ LPCTSTR lpDirectory,
_In_ INT nShowCmd
);
Parameters
hwnd [in, optional]
Type: HWND
A handle to
the parent window used for displaying a UI or error messages. This value can
be NULL if the operation is not associated with a window.
lpOperation [in,
optional]
Type: LPCTSTR
A pointer to
a null-terminated string, referred to in this case as a verb,
that specifies the action to be performed. The set of available verbs depends
on the particular file or folder. Generally, the actions available from an
object's shortcut menu are available verbs. The following verbs are commonly
used:
edit
Launches an
editor and opens the document for editing. If lpFile is not a
document file, the function will fail.
explore
Explores a
folder specified by lpFile.
find
Initiates a
search beginning in the directory specified by lpDirectory.
open
Opens the item
specified by the lpFile parameter. The item can be a file or
folder.
print
Prints the
file specified by lpFile. If lpFile is not a
document file, the function fails.
NULL
The default
verb is used, if available. If not, the "open" verb is used. If
neither verb is available, the system uses the first verb listed in the
registry.
lpFile [in]
Type: LPCTSTR
A pointer to
a null-terminated string that specifies the file or object on which
to execute the specified verb. To specify a Shell namespace object, pass the
fully qualified parse name. Note that not all verbs are supported on all
objects. For example, not all document types support the "print"
verb. If a relative path is used for the lpDirectory parameter
do not use a relative path for lpFile.
lpParameters [in,
optional]
Type: LPCTSTR
If lpFile specifies
an executable file, this parameter is a pointer to a null-terminated
string that specifies the parameters to be passed to the application. The
format of this string is determined by the verb that is to be invoked. If lpFile specifies
a document file, lpParameters should be NULL.
lpDirectory [in,
optional]
Type: LPCTSTR
A pointer to
a null-terminated string that specifies the default (working)
directory for the action. If this value is NULL, the current
working directory is used. If a relative path is provided at lpFile,
do not use a relative path for lpDirectory.
nShowCmd [in]
Type: INT
The flags that
specify how an application is to be displayed when it is opened. If lpFile specifies
a document file, the flag is simply passed to the associated application. It is
up to the application to decide how to handle it. These values are defined in
Winuser.h.
SW_HIDE (0)
Hides the
window and activates another window.
SW_MAXIMIZE (3)
Maximizes the
specified window.
SW_MINIMIZE (6)
Minimizes the
specified window and activates the next top-level window in the z-order.
SW_RESTORE (9)
Activates and
displays the window. If the window is minimized or maximized, Windows restores
it to its original size and position. An application should specify this flag
when restoring a minimized window.
SW_SHOW (5)
Activates the
window and displays it in its current size and position.
SW_SHOWDEFAULT (10)
Sets the show
state based on the SW_ flag specified in the STARTUPINFO structure
passed to the CreateProcess function
by the program that started the application. An application should call ShowWindow with
this flag to set the initial show state of its main window.
SW_SHOWMAXIMIZED (3)
Activates the
window and displays it as a maximized window.
SW_SHOWMINIMIZED (2)
Activates the
window and displays it as a minimized window.
SW_SHOWMINNOACTIVE (7)
Displays the
window as a minimized window. The active window remains active.
SW_SHOWNA (8)
Displays the
window in its current state. The active window remains active.
SW_SHOWNOACTIVATE (4)
Displays a
window in its most recent size and position. The active window remains active.
SW_SHOWNORMAL (1)
Activates and
displays a window. If the window is minimized or maximized, Windows restores it
to its original size and position. An application should specify this flag when
displaying the window for the first time.
Return value
Type: HINSTANCE
If the function
succeeds, it returns a value greater than 32. If the function fails, it returns
an error value that indicates the cause of the failure. The return value is
cast as an HINSTANCE for backward compatibility with 16-bit Windows
applications. It is not a true HINSTANCE, however. It can be cast only to
an int and compared to either 32 or the following error codes
below.
