Bonjour

J'utilise le code suivant pour enlever mon application de la barre des tâches

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
  ShowWindow(application.Handle, SW_HIDE);
  SetWindowLong(application.Handle, GWL_EXSTYLE, WS_EX_TOOLWINDOW);
  ShowWindow(application.Handle, SW_SHOW);

Je l'ai trouvé ici (merci Claudius 40)

Bon maintenant, comment je fais pour la faire apparaître à nouveau dans la barre des tâches ?

Salustre !
Moi, je dirais, après lecture du lien,

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
  ShowWindow(application.Handle, SW_SHOW);
  SetWindowLong(application.Handle, GWL_EXSTYLE, WS_EX_TOOLWINDOW);
  ShowWindow(application.Handle, SW_SHOW);

Mais j'ai pas testé et j'peux me gourrer...
Mes 2 cts,

Salut Jipété

Ca ne fonctionne pas
Je pense plutôt qu'il faut modifier un des paramètres de la seconde ligne

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

  SetWindowLong(application.Handle, GWL_EXSTYLE, WS_EX_TOOLWINDOW);

C'est elle qui cache "l'onglet" de la barre des tâches
Pour ce faire, il faut que la fenêtre de l'appli elle-même soit cachée (1ère ligne)
La 3ème la remet en SW_SHOW une fois l'opération de camouflage terminée

Merci quand même pour ta suggestion

Après avoir utiliser sur SetWindowLong

je tombe sur ca :

SetWindowLong Function

--------------------------------------------------------------------------------


The SetWindowLong function changes an attribute of the specified window. The function also sets the 32-bit (long) value at the specified offset into the extra window memory.

Note This function has been superseded by the SetWindowLongPtr function. To write code that is compatible with both 32-bit and 64-bit versions of Microsoft® Windows®, use the SetWindowLongPtr function.

Syntax

LONG SetWindowLong( HWND hWnd,
int nIndex,
LONG dwNewLong
);
Parameters

hWnd
[in]
Handle to the window and, indirectly, the class to which the window belongs.

Windows 95/98/Me: The SetWindowLong function may fail if the window specified by the hWnd parameter does not belong to the same process as the calling thread.

nIndex
[in] Specifies the zero-based offset to the value to be set. Valid values are in the range zero through the number of bytes of extra window memory, minus the size of an integer. To set any other value, specify one of the following values.
GWL_EXSTYLE
Sets a new extended window style. For more information, see CreateWindowEx.
GWL_STYLE
Sets a new window style.
GWL_WNDPROC

Curieux comme je suis, allons voir dans Windows Style.

WS_BORDER
Creates a window that has a thin-line border.

WS_CAPTION
Creates a window that has a title bar (includes the WS_BORDER style).

WS_CHILD
Creates a child window. A window with this style cannot have a menu bar. This style cannot be used with the WS_POPUP style.

WS_CHILDWINDOW
Same as the WS_CHILD style.

WS_CLIPCHILDREN
Excludes the area occupied by child windows when drawing occurs within the parent window. This style is used when creating the parent window.

WS_CLIPSIBLINGS
Clips child windows relative to each other; that is, when a particular child window receives a WM_PAINT message, the WS_CLIPSIBLINGS style clips all other overlapping child windows out of the region of the child window to be updated. If WS_CLIPSIBLINGS is not specified and child windows overlap, it is possible, when drawing within the client area of a child window, to draw within the client area of a neighboring child window.

WS_DISABLED
Creates a window that is initially disabled. A disabled window cannot receive input from the user. To change this after a window has been created, use EnableWindow.

WS_DLGFRAME
Creates a window that has a border of a style typically used with dialog boxes. A window with this style cannot have a title bar.

WS_GROUP
Specifies the first control of a group of controls. The group consists of this first control and all controls defined after it, up to the next control with the WS_GROUP style. The first control in each group usually has the WS_TABSTOP style so that the user can move from group to group. The user can subsequently change the keyboard focus from one control in the group to the next control in the group by using the direction keys.
You can turn this style on and off to change dialog box navigation. To change this style after a window has been created, use SetWindowLong.


WS_HSCROLL
Creates a window that has a horizontal scroll bar.

WS_ICONIC
Creates a window that is initially minimized. Same as the WS_MINIMIZE style.

WS_MINIMIZEBOX
Creates a window that has a minimize button. Cannot be combined with the WS_EX_CONTEXTHELP style. The WS_SYSMENU style must also be specified.

WS_POPUP
Creates a pop-up window. This style cannot be used with the WS_CHILD style.

WS_POPUPWINDOW
Creates a pop-up window with WS_BORDER, WS_POPUP, and WS_SYSMENU styles. The WS_CAPTION and WS_POPUPWINDOW styles must be combined to make the window menu visible.

WS_SIZEBOX
Creates a window that has a sizing border. Same as the WS_THICKFRAME style.

WS_SYSMENU
Creates a window that has a window menu on its title bar. The WS_CAPTION style must also be specified.

WS_TABSTOP
Specifies a control that can receive the keyboard focus when the user presses the TAB key. Pressing the TAB key changes the keyboard focus to the next control with the WS_TABSTOP style.
You can turn this style on and off to change dialog box navigation. To change this style after a window has been created, use SetWindowLong.


WS_THICKFRAME
Creates a window that has a sizing border. Same as the WS_SIZEBOX style.

Salut Malatar

Et merci pour ton aide
Effectivement, ça fonctionne
Ces aides en angliche me rebutent un peu
Et de toutes façons, ma version D6 perso ne me fournit aucune aide sur SetWindowLong...
