I totally agree with you. I am just the sort of person who can't settle for "If it works it works", I need to know how it works. When I understand exactly what the code is doing behind the scenes, I have feel I have more control over what I can do.

Thanks for that, I suppose overloading them is the only way to go, but I can't understand why an operator for this wasn't created along with new and delete.

nope. new serves for allocating a new object, not reallocating an already existing one...

Hi,

How you get the coordinates (screen) (on Win32) of the icon/exe/shortcut that initiated an exe. I.e how can I obtain the position of the icon/mouse, on which i clicked/double clicked and my application started.

Thanks in advance.

I don't think this is possible. What exactly are you trying to do, popup your window next to the icon or something?

30-Aug-06 19:38

Hi!

I am u using a Tree View control to get windows folder list. I am using IshellFolder Interface and PIDL to add folders to the list. The Problem is that I dont want some virtual folders to be added into the list.

Is there some way to determine whether the folder is virtual folder or some other special folder using its PIDL??

Thanks in advance!

Thx for the link! It was really helpful. I am facing a new problem now.

I am using SHGetDataFromIDList() function to determine the type of the PIDL variable.
Althought the fucntion returns NOERROR, I am not able to check the values of pv.dwDescriptionId structure. WHat I am trying to do is check dwDescriptionId and determine whether it is a FIXED drive or a removable.

here is my code

SHDESCRIPTIONID pv;<br />
	HRESULT hres=SHGetDataFromIDList(pParentFolder,pidl,SHGDFIL_DESCRIPTIONID,&pv,sizeof(SHDESCRIPTIONID));<br />
	if(hres==E_INVALIDARG) <br />
	{<br />
		MessageBox("ERROR","OK",MB_OK);<br />
	}<br />
	if(pv.dwDescriptionId & SHDID_COMPUTER_REMOVABLE)<br />
	{<br />
		MessageBox("REMOVABLE","OK",MB_OK);<br />
		return;<br />
	}

Plz help me!!

Show Desktop Problem which minmizes all the window

payal33530-Aug-06 19:34

30-Aug-06 19:34

when we press the Show Desktop symbol in the quick lauch bar it minimizes the application
but i don't want to do so

So i m able to get the message of the first Show Desktop Click or (WindowsLogo + D)
and i do my processing accordingly i.e. minimize it in the system tray

i get the message in WM_SIZE IN THAT
void CProDlg::OnSize(UINT nType, int cx, int cy)
{

if(nType==SIZE_MINIMIZED)
{
//minimzed it in the system tray
}
}

but when we press it for the second time i.e.Show Desktop Click or (WindowsLogo + D) i m not able to
do the same as it was in the previouly i.e.i don't know how but my application gets popup and is displayed in an unwanted manner.

I am not able to find out which message is send to the dialogbox when the Show Desktop or Keyboard shortcut i.e. (Windows Logo+ D) for the second time.

One thing is clear that the process Shell_TrayWnd program sends message to all the application to minimze
val
/*MinAll*/ 415,
/*MaxAll*/ 416,

accordingly
static HWND hShellWnd = ::FindWindow(_T("Shell_TrayWnd"), NULL);
if(hShellWnd != NULL)
::PostMessage(hShellWnd, WM_COMMAND, MAKELONG(415, 0), NULL);//for minimizing
::PostMessage(hShellWnd, WM_COMMAND, MAKELONG(416, 0), NULL);//for maximizing
This stuff will minimize all the window

Could u please find out the message so that i could remove the flaw.

Not sure I understand you too clearly, but you should be processing the WM_SYSCOMMAND message. This is what's sent to your application to tell it to minimize/restore. The WM_SIZE is only sent after the application has been resized.

if(pMsg->message==WM_SYSCOMMAND)
{

if(pMsg->wParam==SIZE_MINIMIZED||pMsg->lParam==SIZE_MINIMIZED)
{
OnMinimize();
pMsg->lParam=pMsg->wParam=0;
}

if(pMsg->wParam==SIZE_MAXIMIZED||pMsg->lParam==SIZE_MAXIMIZED)
{
OnMaximized();
pMsg->lParam=pMsg->wParam=0;
}

TRIED THIS THING BUT NOT WORKING

Perhaps you should read the docs about the WM_SYSCOMMAND message. Where are those SIZE_MINIMIZED and SIZE_MAXIMIZED coming from? Infact, all you need to do is search the forums, I know for sure this topic has come up at least 3 times in the last week.
