Use SetClassLong( hWnd, GCL_STYLE, GetClassLong( hWnd, GCL_STYLE ) & ~CS_PARENTDC );

Parent & owner

Hi All,

What is the difference between a parent and owner?

I have three functions

CWnd::GetParent ();
CWnd::GetOwner ();
CWnd::GetParentOwner ();

Please help.

Thanks,
NB++

In both cases, the parent or owner has been set as the parent of a control (e.g. SetParent(), or by specifying in the parent parameter of a Create() call).

The difference is that if the control was created with the WS_CHILD style, then the outer window is a PARENT. If it was created without this style, it is only an OWNER.

For a parent window, when the parent is minimized all child controls are hidden. For an owner only, 'owned' windows remain in place and can be minimized separately.

Note that only 'windows' can be owned - 'controls' *must* have a parent and are therefore created with WS_CHILD.

(GetParentOwner() will find the nearest window that is *either* a parent or an owner, but not a child - the others will keep walking up the chain until they find specifically one or the other.)

Hello, im pretty new to using win32 common controls, im wondering how to use the toolbar messages correctyl. Im writing an application that can remove icon's from the system-tray toolbar for annoying applications that dosn't allow you to remove their tray icon.

Here is my code, the button is hidden when i send a TB_HIDEBUTTON, but the toolbar is not resized properly at all, it shows cleary that a button is missing. So i need a way to automatically resize it to the correct size for the new number of buttons. I have tried TB_AUTOSIZE but it dosn't seem to have any effect.

Also, a second problem is the TB_GETBUTTONTEXT message, it returns a strLen of the button string correctly, but the "text" var is always just unilitialized garbage, i dont see why. Anyone knows why?

void main()<br />
{<br />
	HWND hwnd = FindWindowEx(0,0,"Shell_TrayWnd",0);<br />
	hwnd = FindWindowEx(hwnd , 0 ,"TrayNotifyWnd",0);<br />
	hwnd = FindWindowEx(hwnd , 0 ,"SysPager",0);<br />
	hwnd = FindWindowEx(hwnd , 0 ,0,"Notification Area");<br />
<br />
	int index = 0;<br />
	int count = (int)::SendMessage(hwnd, TB_BUTTONCOUNT, 0, 0);<br />
	for(int i=0; i<count; i++)<br />
	{		<br />
		char text[1024];<br />
		int strLen = ::SendMessage(hwnd, TB_GETBUTTONTEXT, i, (LPARAM)text);	<br />
	}<br />
<br />
	BOOL b = ::SendMessage(hwnd, TB_HIDEBUTTON, 0, 1);	<br />
	b = ::SendMessage(hwnd, TB_AUTOSIZE, 0, 0);	<br />
}

Thanks in advance

In your case the application you create and taskbar are two saparate process. So pointer you passed to TB_GETBUTTONTEXT is pointing is vaid for your application aonly. the other applcation cannot access this address. Thats why your getting junk values. What you need to do is allocate some memory in the target process using the VirtualAllocEx() function, then pass that pointer to the message. After the message, you can read the string using the ReadProcessMemory() function.

Hello Friends,

I am trying to change the Text of Start Button. Smile | :)

But not getting sucess.
I am trying following code.

HWND hTray = ::FindWindow(L"Shell_TrayWnd", NULL);<br />
HWND  hStart = ::FindWindowEx( hTray, NULL, L"Button", NULL);<br />
SendMessage(hStart, WM_SETTEXT, 0, (LPARAM)L"MyText");

But nothing seems to happen. But when I see in Spy++ it show the new text.
I dont know what is going on.

Even I dont know Can we change the Text or not. Confused | :confused:

I am using winxp and I can see the changes with your code. It's working fine.
So atleast one thing is confirmed, We can change the text Smile | :)

Nishad S6-Sep-07 21:19

There is a possibility that the start button may be using a bitmap for drawing the face. So if you change the text it wont be updated. It depends on the windows theme that you use. Try changing the theme.

I am Using Win2000. Dont know enything about Themes. Can u guide me through that

Nishad S7-Sep-07 1:13

I meant the look and feel of windows. That is got from Display properties => Appearance.

Since you could verify the change by using Spy++, we can say that the button text is changed.

But since I dont have Win2000 here, I cant test it.

I am not familar with Win2000. Can you change the appearance to Windows 98 classic?

You can take the display propertied by right clicking the desktop.

No its Not Working. I know that start button is saved as a string in Winxp and Win98. Becoz previosly i have changed the Text on Start button using Resource hacker . But dont know how they save the text (Start) in Win2000.

Nishad S7-Sep-07 1:33

As I said before, I have no experience with Win2000. So I am really sorry. Frown | :(
