Is there a way to find the length of a CString in pixles?
There's always one more bug.

The EnumFontFamProc function uses all of its parameters as "input" parameters. The third parameter, 'nFontType', however, has me a little baffled because nowhere prior to it being used, is it initialized.
Therefore my contention is that the test conducted, using 'nFontType' is invalid because it doesn't contain valid data (at least that's what I would like to think), but the program works.
If there's a mystery here, could someone explain it to me. Thanks!
Below is sample code of what I'm talking about.
==========================================
int CALLBACK CMainWindow::EnumFontFamProc(ENUMLOGFONT* lpelf, NEWTEXTMETRIC* lpntm, int nFontType, LPARAM lParam)
{
CMainWindow* pWnd = (CMainWindow*)lParam;
if((pWnd->m_wndCheckBox.GetCheck() == BST_UNCHECKED) || (nFontType & TRUETYPE_FONTTYPE))
do something etc;
etc.
}
===================================
This is the call that activates EnumFontFamProc.
::EnumFontFamilies((HDC)dc, NULL, (FONTENUMPROC)EnumFontFamProc, (LPARAM)this);

nFontType is a DWORD which is a combination of :-
DEVICE_FONTTYPE, RASTER_FONTTYPE, TRUETYPE_FONTTYPE
or it could be 0. In your case you are doing a boolean check on (nFontType & TRUETYPE_FONTTYPE) which will be TRUE only if the TRUETYPE_FONTTYPE bit is set. And there is nothing peculiar about your code either.

Where does 'nFontType' get set to be a combination of the various *FONTTYPE*? Does it get set by the function that activates EnumFontFamProc?
Because it's used as an input parameter, it had to be initialized somewhere and by something!
Thanks!

All 4 parameters are [in] parameters. Usually when we see [in] we instantly think of it as to be initialized by us. But in this case the callback function is called by the API for us. Means they'll populate all the parameters. What's [in] for them is a sort of [out] for us. So you don't have to worry about them being [in] parameters.
If you are implementing some other user based api call, and you wish to use this same callback function as the callback, then you need to populate them. But in your case, you don't have to do that.
I hope I make myself clear.

You can use GetWindowThreadProcessId while you enumerate (using EnumWindows). GetWindowThreadProcessId can be used to find process id based on window handle.

I don't know if you found the answer to your question, if not, try this:
struct FindHwndWithProcIdStruct{
DWORD dwProcId;
HWND hWnd;
};
HWND DoFindWindowWithProcId(DWORD dwProcessId)
{
FindHwndWithProcIdStruct myProcIdStruct = { 0 };
myProcIdStruct.dwProcId = dwProcessId;
::EnumWindows(gfnEnumWindowProc, (LPARAM)&myProcIdStruct);
return myProcIdStruct.hWnd;
}
BOOL CALLBACK gfnEnumWindowProc(HWND hWnd, LPARAM lParam)
{
DWORD dwProcessId = 0L;
DWORD dwThreadId = GetWindowThreadProcessId(hWnd, &dwProcessId);
if (dwProcessId == ((FindHwndWidthProcIdStruct*)lParam)->dwProcId;
{
((FindHwndWidthProcIdStruct*)lParam)->hWnd = hWnd;
return FALSE;
}
return TRUE;
}

How do I select an item in a list box? I'm calling the following code, but that doesn't select anything. What's the correct code to use?
<br />
ServerListCtrl.SetItemState(0, LVIS_SELECTED | LVIS_FOCUSED, LVIS_SELECTED | LVIS_FOCUSED);<br />
ServerListCtrl.EnsureVisible(0, FALSE);<br />
Thanks!

Use SetCurSel() and SetSet().

How? They aren't members of CListCtrl 
|
|

Oh. Those functions work for a list box, not a list control.

That looks right to me (although you're using a list view control, not a list box, they are different things). If your control doesn't have the LVS_SHOWSELALWAYS style, the selection won't be visible when the control does not have the focus, so maybe that's causing the problem.

I want to display the database records in the listbox. All I have done with database is specifiying the database support while creating the project so that I get a record by record display.
Could anyone tell how to implement it?
Thank You

A lot depends on what kind of database access you are using and what kind of database you are accessing. ADO is the easiest method and is well documented with examples at http://www.codeproject.com/database/

Programming is great. First they pay you to introduce bugs into software. Then they pay you to remove them again.

Looking for an ACM (Audio Compression Manager) tutorial somewhere. I've just made an app that enumerates all the different drivers and formats, but i don't know how to convert from one format to another.
Thanks

Hi
do you know how to include inline assembler code in Dev-C++?
I tried __asm {}, _asm {}, asm {}, __asm__ {}, but nothing works...
-Dominik

From MSDN:
int power2( int num, int power )
{
__asm
{
mov eax, num ; Get first argument
mov ecx, power ; Get second argument
shl eax, cl ; EAX = EAX * ( 2 to the power of CL )
}
}
- Anders
Money talks, but all mine ever says is "Goodbye!"

Your example doesn't work.
Error: "parse error before { in line xxx"
