Change collapse/expand icons in treeview

In a tree control I' like to replace the collapse/expand icons. Is this even possible?

You can change the icons alongside the + ans - signs with the TreeView_SetImageList[^] command.

It's time for a new signature.

I'm not sure on this as I have only used the TVSIL_NORMAL image list. I would suggest you give it a try and see what happens.

If you mean you wish to replace the + and - images themselves then I believe you would need to draw the tree yourself, using custom draw.

Diff bw BOOL and bool??

hello guys...I know what is bool but what is the difference between BOOL and bool. Some other examples are TRUE and true, FALSE and false, LONG and long. Why do we need such key words in capitals.

Re: Diff bw BOOL and bool??

Richard MacCutchan15-Aug-10 0:50

The ones in capitals are a throwback to the early days before these types were part of the language. They were added to the C headers to improve readability of programs.

It's time for a new signature.

The one in small case is C/C++ native data type that is one byte long and is used to store boolean values. The one in caps is M$ typedef'd variable. It is (usually ?) same as int or long which of course range in sizes from 2 to 4 bytes.

I personally use caps bool only to confirm to MFC/Win32 APIs and I use the native one everywhere else.

...byte till it megahertz...

What keywords are those? BOOL, LONG, TRUE and FALSE aren't keywords in C or C++?

I'd assume the ones you're talking about are a part of a Microsoft operating system interface (either typedeffed or defined) and are there to aid portability and/or get over particular problems with specific compilers.

The BOOL type is a redefinition of int
where FALSE is a int value of 0
and TRUE is a int value of 1...

...so you could define for example your own int UNDEFINED with value of -1
and pass it to a BOOL variable without any warning Smile | :)

The bool type is a "real bool" of MS VC++,
its variables take only the values true or false, 1 or 0 without warnings Smile | :)

The pairs long/LONG, char/CHAR, etc - are the direct redefinitions (but not bool/BOOL) Smile | :)

the big onte are macros (per #define) declared types, the ones with small caps are parts of the languaage.

It should be ShowWindow(SW_MINIMIZE); - WS_ values are windows styles, SW_ values are ShowWindow() command parameters.

I would apply just the following to the words of Richard:
there are two - known for me - reasons for "a dialog" to be minimized:
- the dialog is modeless (could be a child of the desktop Smile | :)

)
- the dialog is the application window (the style WS_EX_APPWINDOW could be applied in OnInitDialog() Smile | :)

)

An emulation of the second reason:

int CYourDialog::OnInitDialog()
{
  int iResult = CDialog::OnInitDialog();

  // Adding of the APP-style...
  LONG lStyle = GetWindowLong(GetSafeHwnd(), GWL_EXSTYLE) | WS_EX_APPWINDOW;
  SetWindowLong(GetSafeHwnd(), GWL_EXSTYLE, lStyle);
  // Now the dialog should be ready to be minimized...
  // CAUTION: the parent window stays disabled,
  // if the dialog is not modeless... :)

  //...

  return iResult;
}
