Combo Box Styles

Hi,

I am creating a combo box via C++ code in order to abtain the third combobox on the right shown in the picture below:

http://i.msdn.microsoft.com/Bb775791...s,VS.85%29.png

The following is the code:

Code:

---

HWND hvComboBox = CreateWindowEx(0,WC_COMBOBOX,NULL,
WS_CHILD | WS_VISIBLE | CBS_DROPDOWNLIST | CBS_HASSTRINGS | WS_VSCROLL | 0x00002000,
60, 62, 250, 100,
hwnd,(HMENU)IDC_COMBO1,hInst,NULL);

---

where I guess the 0x00002000 should give the combobox that special style (the control was originally created with ResEdit)

Unfortunately, I am still getting a normal style like the combo in the middle shown in the picture...what am I doing wrong?

thanks

Checkout the styles at http://msdn.microsoft.com/en-us/libr...be(VS.80).aspx

I checked them out, still I can't find the style ResEdit created

Code:

---

/*

#define CBS_SIMPLE            0x0001L
#define CBS_DROPDOWN          0x0002L
#define CBS_DROPDOWNLIST      0x0003L
#define CBS_OWNERDRAWFIXED    0x0010L

#define CBS_HASSTRINGS        0x0200L
#define CBS_NOINTEGRALHEIGHT  0x0400L

#if(WINVER >= 0x0400)
#define CBS_UPPERCASE        0x2000L
#define CBS_LOWERCASE        0x4000L
#endif /* WINVER >= 0x0400 */

#endif  /* !NOWINSTYLES */

ok, thanks. Yet, it seems there's no way to make it look like that

CBS_DROPDOWNLIST should do that. Maybe I didn't understand your question. What is the problem?

I get a regular combobox, I dont get the third on the left shown in teh picture I posted

Here's an (almost) cut-n-past of your code:

Code:

---

  HWND hvComboBox1,hvComboBox2,hvComboBox3;
  HINSTANCE hInst=AfxGetInstanceHandle();

  hvComboBox1 = CreateWindowEx(0,WC_COMBOBOX,L"CBS_DROPDOWNLIST",
WS_CHILD | WS_VISIBLE | CBS_DROPDOWNLIST | CBS_HASSTRINGS | WS_VSCROLL | 0x00002000,
60, 62, 250, 100,
m_hWnd,NULL,hInst,NULL);

  hvComboBox2 = CreateWindowEx(0,WC_COMBOBOX,L"CBS_DROPDOWN",
WS_CHILD | WS_VISIBLE | CBS_DROPDOWN | CBS_HASSTRINGS | WS_VSCROLL | 0x00002000,
60, 92, 250, 100,
m_hWnd,NULL,hInst,NULL);

  hvComboBox3 = CreateWindowEx(0,WC_COMBOBOX,L"CBS_SIMPLE",
WS_CHILD | WS_VISIBLE | CBS_SIMPLE | CBS_HASSTRINGS | WS_VSCROLL | 0x00002000,
60, 122, 250, 100,
m_hWnd,NULL,hInst,NULL);

Are you talking about its look or its behavior?
The “regular” combobox allows you to edit your entry, while the CBS_DROPDOWNLIST – only to pick from the list.
If you are concerned about the look – this is most likely controlled by your theme and depends on the version of Windows.

that is not working for me :-( I am on windows vista...by the way, do you think I should use SetWindowTheme() to force a stlye?

I guess I should turn to different gui libraries like QT or GTK+

Only if you want to P*ss off your users. They chose the style; the program shouldn't second-guess them.

My capture was from Windows 7 BTW, so it got me thinking that maybe you're not using the right manifest for common controls or something and are stuck with the old windows95 look.

What exactly do you mean by "not working for me"? I assumed you meant that you were getting the wrong behavior from the control, but do you really mean the style doesn't look right?

Yeah, I am stuck with teh old win95 look. I tried your code and the style looks bad. Here's is an example (shown from ResEdit)

while this is the same create via C++ code using CreateWindowEx for the main window and its single child controls:

How come thru ResEdit I get that style whereas in pure code I don't?

thanks

Add a manifest dependency for Common controls 6.0 to your stdafx.h file:

Code:

---

#ifdef _UNICODE
#if defined _M_IX86
#pragma comment(linker,"/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='x86' publicKeyToken='6595b64144ccf1df' language='*'\"")
#elif defined _M_IA64
#pragma comment(linker,"/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='ia64' publicKeyToken='6595b64144ccf1df' language='*'\"")
#elif defined _M_X64
#pragma comment(linker,"/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='amd64' publicKeyToken='6595b64144ccf1df' language='*'\"")
#else
#pragma comment(linker,"/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='*' publicKeyToken='6595b64144ccf1df' language='*'\"")
#endif
#endif
