depending on virus..actaully if this virus is written by hobbiest programmer you might recover the content. but if it written by experienced programmer you may not.. might be he has replaced the content of recoverable memory with some junk character making it non recoverable atall!

Hi,

Does anyone know how I can include a menu with draggable/rearrangeable items in my software? The items can be rearranged by dragging it like in firefox, ie and start menu.

I've been searching around the net for that kind of menu but can't find one. I have a feeling that it exist, I just can't find it.

Thanks

Hi all. I'd just like to find out how to use this code on a article someone wrote a while back. I'd like to use it with out having to use a dialog. So it would be console when compiled. Here is the link http://www.codeproject.com/system/Hack_Windows_Task_Manager.asp.I know the part that i'd like to use is in the SendMessage() API. But i dont think thats the only thing i need to do. Im sure the entire BOOL function is what i'll need. If anyone has any suggestions please let me know. Thanx in advance!

As both EnumChildWindows() and SendMessage() can be used in a console application, what is it that is troubling you?

Whats bothering me is that im trying to see if i need the entire function of BOOL, the code:

<br />
BOOL CALLBACK EnumChildProcedure(HWND hWnd,LPARAM lParam)<br />
{<br />
	char name[256]; <br />
	GetWindowText(hWnd,name,256);<br />
<br />
	char ClassName[256];<br />
	GetClassName(hWnd,ClassName,256);<br />
<br />
	if((strcmp(ClassName,"SysListView32")==0)&&(strcmp(name,"Processes")==0))<br />
	{<br />
		::SendMessage(hWnd,LVM_DELETECOLUMN,(WPARAM)0,0);<br />
	}<br />
<br />
	if((strcmp(ClassName,"SysListView32")==0)&&(strcmp(name,"Tasks")==0))<br />
	{<br />
		::SendMessage(hWnd,LVM_DELETECOLUMN,(WPARAM)0,0);<br />
	}<br />
<br />
	if(name==NULL)<br />
		return FALSE;<br />
	return TRUE;<br />
}<br />

If you use EnumChildWindows(), you will need a callback function. What you put in it is up to you.

How do i declare a bool callback function? I keep getting undeclared variable when i try to compile.

<br />
EnumChildWindows(variable, function, NULL);<br />
<br />
BOOL CALLBACK function(HWND variable, LPARAM lParam){<br />
 ...//Some code<br />
}<br />

Thanx in advance!

Probably because you are referencing it (i.e., function()) before it has been declared.

Can I get some example programs of class Savings?
I am new to programing and by seeing related programs, I'll be able to develope a general technigue for developing classes.
Thanks

You mean like:

class Savings
{
public:
    Savings()
    ~Savings();
};

Can you more explain about class Savings?

Hi,

I need to serialize/deserialize object/container which can contain properties and CArray based dynamic stuff to/from XML.

Is there any useful libraries/implementations for XML serialization?

Will appreciate any feedback.

You could try libxml. It can save/load XML files.

I've got a class that wraps GDI+. In the constructor I call GdiplusStartup, and in the destructor I call GdiplusShutdown. This could result in multiple startup & shutdown calls. (And possibly several startup calls before any shutdown calls) Is it safe to make these calls multiple times?

What does the documentation say?

Not much relevant to my question.

Seems pretty clear to me Roll eyes | :rolleyes:

"Each call to GdiplusStartup should be paired....."

GdiplusShutdown Function

The GdiplusShutdown function cleans up resources used by Microsoft Windows GDI+. Each call to GdiplusStartup should be paired with a call to GdiplusShutdown.

I don't know.

The docs state:

"You must call GdiplusStartup before you create any GDI+ objects,
and you must delete all of your GDI+ objects (or have them go out
of scope) before you call GdiplusShutdown."

Although there's a token associated with each startup/shutdown pair,
the token (or any other context) isn't used when working with GDI+
objects. That means there's no internal context relating created GDI+
objects with a GdiPlusStartup() call.

If I had to guess, I'd say it will work fine - the DLL is probably released
when the last token is returned to GdiPlusShutdown(). It's not documented,
however, so that's a complete assumption, and relying on that assumption
could be disastrous in the future..

To be safe, I personally chose (and still choose) to do this pair of calls ONCE
for an entire application.

This can be done with a singleton class wrapping the gdiplus dll (may fit nice with
your wrapper class), or simply calling the startup/shutdown functions during app
initialization/cleanup.

I'd rather just do the initialization once like you suggest, but the code I'm working on is a module to be shared among different client apps, so I can't be sure a priori if the client is already using GDI+. Thanks for the reply,
