Hello

Is there a way to hide a parent window of a win32 application from the windows taskbar (as in hide the little box with the window name and icon in the taskbar) and also the alt+tab window (as in the window which appears when you press alt+tab)?

Thanks for your help!

Add the WS_EX_TOOLWINDOW extended style to your top-level window.

Thanks, Mike Smile | :)

Although I would like a window without a caption or border.. Is there any way to do it like that?

Thanks for your help!

Just remove the corresponding styles - WS_CAPTION and WS_BORDER

Thanks again :p

You mean with SetWindowLong()? How do you remove multiple styles? Sigh | :sigh:

Thanks for your help!

Bit twiddling. For example, to remove the caption and border, use:

style &= ~(WS_BORDER | WS_CAPTION);

Do you still have to explicitly remove the WS_EX_APPWINDOW style?

Peace!

How about creating it as a child of a hidden window?

The child window will appear in the alt+tab window :p

Thanks anyway Smile | :)

Class structure with character array

You still have to add in the WS_POPUP style for that to work (IIRC).

Peace!

Greetings,

I am very new to C++ and after many searches I am unable to figure out how to set the values of my array containing a character string.

class DataStruct
{
public:
char *mName;
char mInitial;
int mId;
int mAge;
int mDay;

DataStruct(char *Def_mName = "Paddy", char Def_mInitial = 'A' , int Def_mId = 1, int Def_mAge = 1, int Def_mDay = 1)
{
cout << endl << "Constructor Called ";
mName = new char [ strlen(Def_mName) + 1 ];
strcpy_s (mName, strlen(Def_mName) + 1, Def_mName);
mInitial = Def_mInitial;
mId = Def_mId;
mAge = Def_mAge;
mDay = Def_mDay;
}

When trying to use:

DataStruct data1[2] = { ("Andy",'A',1,20,30), ("Andy",'A',1,20,30 )};

I get the error:
error C2440: 'initializing' : cannot convert from 'int' to 'DataStruct'

Clearly I am not understanding somthing correctly either about strings or pointers, I am trying not to use specific string lengths if possible in this scenario.

Please can someone tell me what command I should be using to create this array, also if possible I would like to dynamicaly create the array data1 using new if anyone would be kind enough to show that example too.

Kind regards,

BS

Two problems:

1) You're using the wrong brackets in your initializer list:

DataStruct data1[2] = { ("Andy",'A',1,20,30), ("Andy",'A',1,20,30 )};

should be

DataStruct data1[2] = { {"Andy",'A',1,20,30}, {"Andy",'A',1,20,30 }};

2) You can't use an initializer list like this unless you remove the constructor from the struct.
See Compiler Error C2552[^] for details.

Many thanks Mark,

It did indeed work as you suggested, I am presuming that the compiler error was raised because the character array was not a fixed length.

I am plagued with a habbit of throwing myself off the deep end, anyway, thanks again for your very fast response.

Smile | :)

Actually it was the constructor...

From the docs:

"The following represent the reasons C2552 may fire when an aggregate initialization is attempted
on a type:
The type has one or more user-defined constructors."

where agregate is defined as:

"An aggregate type is an array, class, or structure type which:
Has no constructors
Has no nonpublic members
Has no base classes
Has no virtual functions "

Cheers!

If you never threw yourself off the deep end you would learn a lot less - keep diving. Big Grin | :-D

You can keep the ctor if you initialize the array like this:

DataStruct data1[2] = { DataStruct("Andy",'A',1,20,30), DataStruct("Andy",'A',1,20,30) };

How to handle click event on icon which is placed on status bar?

Answers are appreciated.

You can respond to the message you indicated in NOTIFYICONDATA.uCallbackMessage when you
added the icon with Shell_NotifyIcon().

NOTIFYICONDATA.hWnd needs to be valid and NOTIFYICONDATA.uFlags needs to have the NIF_MESSAGE
flag as well.

Or were you referring to a status bar in an application window... Smile | :)
