Enclosing interface:

WinBase

public static class WinBase.STARTUPINFO
extends Structure

Specifies the window station, desktop, standard handles, and appearance of the main window for a process at creation time.

cb

public WinDef.DWORD cb

The size of the structure, in bytes.

lpReserved

public String lpReserved

Reserved; must be NULL.

lpDesktop

public String lpDesktop

The name of the desktop, or the name of both the desktop and window station for this process. A backslash in the string indicates that the string includes both the desktop and window station names. For more information, see Thread Connection to a Desktop.

lpTitle

public String lpTitle

For console processes, this is the title displayed in the title bar if a new console window is created. If NULL, the name of the executable file is used as the window title instead. This parameter must be NULL for GUI or console processes that do not create a new console window.

dwX

public WinDef.DWORD dwX

If dwFlags specifies STARTF_USEPOSITION, this member is the x offset of the upper left corner of a window if a new window is created, in pixels. Otherwise, this member is ignored. The offset is from the upper left corner of the screen. For GUI processes, the specified position is used the first time the new process calls CreateWindow to create an overlapped window if the x parameter of CreateWindow is CW_USEDEFAULT.

dwY

public WinDef.DWORD dwY

If dwFlags specifies STARTF_USEPOSITION, this member is the y offset of the upper left corner of a window if a new window is created, in pixels. Otherwise, this member is ignored. The offset is from the upper left corner of the screen. For GUI processes, the specified position is used the first time the new process calls CreateWindow to create an overlapped window if the y parameter of CreateWindow is CW_USEDEFAULT.

dwXSize

public WinDef.DWORD dwXSize

If dwFlags specifies STARTF_USESIZE, this member is the width of the window if a new window is created, in pixels. Otherwise, this member is ignored. For GUI processes, this is used only the first time the new process calls CreateWindow to create an overlapped window if the nWidth parameter of CreateWindow is CW_USEDEFAULT.

dwYSize

public WinDef.DWORD dwYSize

If dwFlags specifies STARTF_USESIZE, this member is the height of the window if a new window is created, in pixels. Otherwise, this member is ignored. For GUI processes, this is used only the first time the new process calls CreateWindow to create an overlapped window if the nHeight parameter of CreateWindow is CW_USEDEFAULT.

dwXCountChars

public WinDef.DWORD dwXCountChars

If dwFlags specifies STARTF_USECOUNTCHARS, if a new console window is created in a console process, this member specifies the screen buffer width, in character columns. Otherwise, this member is ignored.

dwYCountChars

public WinDef.DWORD dwYCountChars

If dwFlags specifies STARTF_USECOUNTCHARS, if a new console window is created in a console process, this member specifies the screen buffer height, in character rows. Otherwise, this member is ignored.

dwFillAttribute

public WinDef.DWORD dwFillAttribute

If dwFlags specifies STARTF_USEFILLATTRIBUTE, this member is the initial text and background colors if a new console window is created in a console application. Otherwise, this member is ignored. This value can be any combination of the following values: FOREGROUND_BLUE, FOREGROUND_GREEN, FOREGROUND_RED, FOREGROUND_INTENSITY, BACKGROUND_BLUE, BACKGROUND_GREEN, BACKGROUND_RED, and BACKGROUND_INTENSITY. For example, the following combination of values produces red text on a white background: FOREGROUND_RED| BACKGROUND_RED| BACKGROUND_GREEN| BACKGROUND_BLUE

dwFlags

public int dwFlags

A bit field that determines whether certain STARTUPINFO members are used when the process creates a window.

wShowWindow

public WinDef.WORD wShowWindow

If dwFlags specifies STARTF_USESHOWWINDOW, this member can be any of the values that can be specified in the nCmdShow parameter for the ShowWindow function, except for SW_SHOWDEFAULT. Otherwise, this member is ignored. For GUI processes, the first time ShowWindow is called, its nCmdShow parameter is ignored wShowWindow specifies the default value. In subsequent calls to ShowWindow, the wShowWindow member is used if the nCmdShow parameter of ShowWindow is set to SW_SHOWDEFAULT.

cbReserved2

public WinDef.WORD cbReserved2

Reserved for use by the C Run-time; must be zero.

lpReserved2

public ByteByReference lpReserved2

Reserved for use by the C Run-time; must be NULL.

hStdInput

public WinNT.HANDLE hStdInput

If dwFlags specifies STARTF_USESTDHANDLES, this member is the standard input handle for the process. If STARTF_USESTDHANDLES is not specified, the default for standard input is the keyboard buffer. If dwFlags specifies STARTF_USEHOTKEY, this member specifies a hotkey value that is sent as the wParam parameter of a WM_SETHOTKEY message to the first eligible top-level window created by the application that owns the process. If the window is created with the WS_POPUP window style, it is not eligible unless the WS_EX_APPWINDOW extended window style is also set. For more information, see CreateWindowEx. Otherwise, this member is ignored.

hStdOutput

public WinNT.HANDLE hStdOutput

If dwFlags specifies STARTF_USESTDHANDLES, this member is the standard output handle for the process. Otherwise, this member is ignored and the default for standard output is the console window's buffer.

hStdError

public WinNT.HANDLE hStdError

If dwFlags specifies STARTF_USESTDHANDLES, this member is the standard error handle for the process. Otherwise, this member is ignored and the default for standard error is the console window's buffer.

WinBase.STARTUPINFO

public WinBase.STARTUPINFO()

getFieldOrder

protected List getFieldOrder()

Description copied from class: Structure

Return this Structure's field names in their proper order. For example,

 protected List getFieldOrder() {
     return Arrays.asList(new String[] { ... });
 }
 

IMPORTANT When deriving from an existing Structure subclass, ensure that you augment the list provided by the superclass, e.g.

 protected List getFieldOrder() {
     List fields = new ArrayList(super.getFieldOrder());
     fields.addAll(Arrays.asList(new String[] { ... }));
     return fields;
 }
 

Field order must be explicitly indicated, since the field order as returned by Class.getFields() is not guaranteed to be predictable.
