Re: Where is BIF_USENEWUI defined? MSDN says i can use it but VC says unknown identifier.

You need #define _WIN32_IE 0x500

Defined it is stdafx.h replace any definition if it already exists

I'm not sure what you meant, but if i remember correctly, stdafx is used for MFC, and i'm not using MFC.

You should do this before including windows.h.

You can also change it in the project settings. In C/C++ -> Preprocessor -> Symbol Defines add _WIN32_IE = 0x500

   Just a small FWI: stdafx.h is (usually) used as the header file that creates the pre-compiled header (PCH) file.  It has nothing to do with MFC.

   The reason it was mentioned to put the #define _WIN32_IE 0x500 (near the top) of the stdafx.h file was so that it was #defined before the inclusion of any win32 header files that might be looking for that symbol.

   Lastly, you may need to update your SDK files (Platform SDK) in order to get a header file that has the BIF_USENEWUI value in it.  The "stock" files you get in an VC++ 6.0 install will not have it.

   Peace!

How do i get an the iItem property of an item in a ListView if i have it's lParam value?

Re: How do i get an the iItem property of an item in a ListView if i have it's lParam value?

13-Jun-02 1:40

I can't use ListView_GetItem cause it requires iItem to be filled...

13-Jun-02 1:53

Try to use ListView_FindItem.

int ListView_FindItem(HWND hwnd, int iStart, const LPLVFINDINFO plvfi);

typedef struct tagLVFINDINFO
{
UINT flags;
LPCTSTR psz;
LPARAM lParam;
POINT pt;
UINT vkDirection;
} LVFINDINFO, FAR* LPFINDINFO;

1. Initialize a LVFINDINFO structure with your lParam value and flags set to
LVFI_PARAM.
2. Then call ListView_FindIntem with iStart = -1.
3. Returned value is what you need to get all other properties.

if your lparam is a ptr to a data structure, may be you can store the hitem in it when you create your listview items

Do you know how should i add MFC support to ATL project?
When i try to use #include <afxwin.h> in stdafx.h and i declare a CString in a method i get the following:

Linking...
mfcs42d.lib(dllmodul.obj) : error LNK2005: _DllMain@12 already defined in a.obj
mfcs42d.lib(dllmodul.obj) : warning LNK4006: _DllMain@12 already defined in a.obj; second definition ignored

LINK : warning LNK4098: defaultlib "MSVCRT" conflicts with use of other libs; use /NODEFAULTLIB:library
Debug/a.dll : fatal error LNK1169: one or more multiply defined symbols found

I've defined _AFXDLL and _USRDLL in the project settings and still doesn't work.

Here is how you fix it

1. Add a CWinApp derived class add InitIntance and ExitInstance functions.

2. Define _AFXDLL, _USRDLL

3. Move code from DllMain to appropriate InitInstance or ExitInstance method

4. Remove DllMain

Build and it will compile Smile | :)

Also set the linker option to link with MFC statically or dynamically

Hi everyone. I have a dialog with 2 combo boxes, one is for setting what kind of data which will be put into the second combo box. For example, "String" will set the data box into a dropdown were the user can type in a string, or "boolean", which would set the data box into a drop list (where there are two entires, "Yes" or "No". I want to be able to do this dynamically, as the user selects either "String" or "boolean".

I tried the following to set the data combobox from a dropdown to a drop list, with the dropdown already successfully created by default in the resource editor. When this code is run, the combo box font changed, the size of the box changed, and I could not set the drop down width to anything, and the width would be zero. The combobox did change to droplist though.

Is it possible to change the combobox from sropdown to drop list dynamically? Is there a correct way to do it, so I don't have to use an extra combobox? Thanks in advance for any help!

<br />
// pFrom is a pointer to a CComboBox control<br />
CRect rect;<br />
pFrom->GetWindowRect(rect);<br />
ScreenToClient(rect);<br />
<br />
pFrom->DestroyWindow();<br />
pFrom->Create(CBS_DROPDOWNLIST, rect, this, IDC_CBO_DATA);<br />
pFrom->AddString("Yes");<br />
pFrom->AddString("No");<br />
pFrom->SetCurSel(0);<br />
pFrom->ShowWindow(TRUE);<br />
pFrom->EnableWindow(TRUE);<br />
pFrom->SetDroppedWidth(70);<br />
<br />

Unfortunately some styles are not changeable once the control has been created. This is one of them.

if you cannot change the style workaround is have to two controls drowndown and droplist in the same place in the dialog and show the one you need

You cannot change this style at runtime. You have the right idea: delete the combobox and create another with the appropriate style. First save all the relevant attributes of the original combo and stuff them into the new one when it's ready. I used the following code to change from DROPDOWN to DROPLIST:

// save all the relevant attributes of the existing combo, then destroy it and
// create a new one with CBS_DROPDOWNLIST style.
// (ModifyStyle(CBS_DROPDOWN, CBS_DROPDOWNLIST) won't work)
DWORD dwStyle = m_Combo.GetStyle();
DWORD dwExStyle = m_Combo.GetExStyle();
int nID = m_Combo.GetDlgCtrlID();
CWnd *pPrevWindow = m_Combo.GetNextWindow(GW_HWNDPREV);
CWnd *pParentWnd = m_Combo.GetParent();
CFont *pFont = m_Combo.GetFont();
m_Combo.GetWindowRect(rect);
pParentWnd->ScreenToClient(rect);
m_Combo.DestroyWindow();
dwStyle &= ~CBS_DROPDOWN;
dwStyle |= CBS_DROPDOWNLIST;
m_Combo.CreateEx(dwExStyle, "COMBOBOX", "", dwStyle, rect, pParentWnd, nID);
m_Combo.SetFont(pFont, FALSE);
m_Combo.SetWindowPos(pPrevWindow, 0, 0, 0, 0, SWP_NOMOVE|SWP_NOSIZE);

Hope this helps,

Regards,
Phil

Thanks! Your code worked great, except the dropdown height was not preserved, and I could not change it via SetDroppedWidth(). So the user could not see the "Yes" and "No" I put in the combobox. The font and such were preserved. Why couldn't I change the dropped width?
