Subject: Re: How To Start Your Web Browser?
Thanks. Mats, another member of this list server, sent me a URL that I =
borrowed a code snippet from. The code that I borrowed was from the
Code =
Guru's web site, (thanks Code Guru), and it went something like this:
HINSTANCE CHyperLink::GotoURL(LPCTSTR url, int showcmd)
{
TCHAR key[MAX_PATH + MAX_PATH];
// First try ShellExecute()
HINSTANCE result =3D ShellExecute(NULL, _T("open"), url, NULL,NULL, =
showcmd);
// If it failed, get the .htm regkey and lookup the program
if ((UINT)result <=3D HINSTANCE_ERROR) {
if (GetRegKey(HKEY_CLASSES_ROOT, _T(".htm"), key) =3D=3D =
ERROR_SUCCESS) {
lstrcat(key, _T("\\shell\\open\\command"));
if (GetRegKey(HKEY_CLASSES_ROOT,key,key) =3D=3D =
ERROR_SUCCESS) {
TCHAR *pos;
pos =3D _tcsstr(key, _T("\"%1\""));
if (pos =3D=3D NULL) { // No quotes =
found
pos =3D strstr(key, _T("%1")); // Check for =
if (pos =3D=3D NULL) // No =
parameter at all...
pos =3D key+lstrlen(key)-1;
else
*pos =3D '\0'; // Remove the =
parameter
}
else
*pos =3D '\0'; // Remove the =
parameter
lstrcat(pos, _T(" "));
lstrcat(pos, url);
result =3D (HINSTANCE) WinExec(key,showcmd);
}
}
}
return result;
}
I hope the formatting of this message is decent. I not certain as to
the =
proper settings for a compliant universal email just yet. A friend uses
=
Pegasus email and she says she can never read Microsoft Outlook's =
default settings. I haven't tried any new settings yet so I do hope
this =
works. Anyway, thanks for the suggestion.
PS, I must have 2 dozen books on C++ and I can't seem to find the =
ShellExecute command in any of them! Isn't it ironic?

If you want to open a browser with a parcticular page in it -
you can use ShellExecute() function with the http address as a parameter
(have a look in help for the usage of that function).
Else you can find the path of the default browser in the registry at
HKEY_LOCAL_MACHINE\Software\Classes\htmlfile\shell\open\command

Subject: Re: How to find a directory is exit ?
Hi,
It is a good way to determine it:
DWORD dwAttrs = GetFileAttributes(sDir);
if ( dwAttrs == 0xffffffff )
{
if(GetLastError() != ERROR_FILE_NOT_FOUND)
TRACE("GetFileAttributes(%s) returns error code !", Dir);
return (FALSE); // Not exists
}
if ( (dwAttrs & FILE_ATTRIBUTE_DIRECTORY) != 0 )
return (TRUE); // Directory exists
return(FALSE); // Not exists (only file with the same name exists)

Subject: ActiveX Container support
Hi,
I need to write an app with activex document support. I was working with
vc4.2, but now I'm working with vc5.0. I thought vc5.0 would have this
functionality but there is only support to activex servers.
Is there any source of information, samples, etc.
Any idea?
Thanks in advance

Subject: Re: VSS, Help
Dave,
Thanks for replying. I knew I left out a few details in my original
message.
I'm running VSS version 5.0 on Win95. Since you mentioned "each pane",
I'm
guessing you are using the format 'Visual'. (Two, side-by-side panes.)
My
problem is in the format 'SourceSafe'. (Single pane, lines marked
INS(erted),
DEL(eted), etc.) These difference formats may only be available in VSS
version
5.0 and above. (I've never used earlier versions.) I can look at half a
pane
of 'white space' to the right of the truncated lines, so I don't think a
horizontal scroll bar would help, even if there was one in this view.
Does anyone have any other ideas?
Jeff Nygren
(P.S. Dave, I DO appreciate your reply, even if it wasn't the solution
to my
problem.)

When I look at differences in files, I have two scroll bars at the
bottom
of each pane and can move left/right. I am on NT 4.0. I am pretty sure
it
works on Win95. Do not know about nt 3.51. I have heard rumors about
horizontal scroll bars not working under some condition. Are you running
service pack 3 if NT 4.0?

Subject: VSS, Help
I apologize for this being a little off-topic (only a little).
Can any of you who are using Visual SourceSafe for you source control
system,
help me with this problem? I select a project and click "File/Project
Difference". Then I select any of the 'Changed' files and click the
"File/Project Difference" button in the "Project Difference" window. In
the
"Difference Options" dialog, I have the format "SourceSafe" selected
and I
click OK. The "Differences for <file>" that is displayed is truncated at
around the 80th column! I can't find any way to get SourceSafe to
display
the
full line! This is pretty worthless when the changes are beyond the
column
where the display or printout is truncated.
If any of you can tell me how to get around this problem, I would
greatly
appreciate it. Thanks.

Subject: Windows API Messages
Hi all!
For various reasons (largely, but not entirely related to legacy code),
my
company codes the API directly, without using MFC. I'm having trouble
getting a handle on the Windows API messages (no pun intended). I found
what appears to be a comprehensive list of messages known to the system,
but it's too big to be managable. Does anybody have a list of what the
prefixes on the messages stand for? That would go a long way toward
making
that list useful. For instance, WM_CLOSE has a WM_ prefix which I know
stands for Windows Message. Similary, WN_ is Windows Notify.
Any ideas? I can't hit the web from my desk just now, so a resource
e-mailed to me would be great, but don't shy away from sending a url if
that's all you've got; I'll just have to surf to it at home.
TIA!

Thanks for the suggestion,
I am using a modal dialog box, specifying it with DS_MODALFRAME. I tried
using SetCapture in the WM_INITDIALOG section of the dialog box
procedure
and ReleaseCapture before EndDialog, but with no luck. I can still click
on another window and windows transfers focus there.
Thanks,
Tim

Subject: Re: Retaining keyboard focus.
SDK documentation states that: "Dialog boxes with the DS_SYSMODAL style
receive the WS_EX_TOPMOST window style but no other special properties
or
styles; this means the user still has access to other windows on the
desktop even though a DS_SYSMODAL dialog box may be displayed."
I'll try it, but it doesn't seem promising.
Thanks,
Tim

Subject: TrackPopupMenuEx
Environment: VC++ 4.1 / Win95
hi.
i have a new problem.
when i load a menu from a menu resource and then try to call
::TrackPopupMenuEx()
or CMenu::TrackPopupMenu(), either way windows draws a small rectangle
and only
after i move on top of this tiny rectangle, does the menu pop out? What
is happening
here, any clues. On the other hand, if i do not load the menu from menu
resource,
but instead Create the menu on the fly using CreatePopupMenu() /
AppendMenu(),
TrackPopupMenuEx() shows the menu fine without any little rectangle.
What am
missing?
Another problem which seems to perplex me is like this. I have the new
user.exe /
user32.dll files from microsoft which have certain GUI enhancements of
Memphis
like gradient CaptionBars and animated sliding menus. Again, my problem
concerns
menus. When i write a menu in a MFC Program, the menu doesn't slide like
the ones
in memphis but come straight up like Win95. But if i write a standard
WinAPI32
application, the same TrackPopupMenuEx() makes the menu slide. I am
really confused
as to what is happenening. Has Microsoft hardcoded the menu code in MFC.
That
seems very unlikely.
The third problem concerns menus with a bitmap logo on the side of a
menu like Norton
Utilities. Can anyone throw light on how to do this. The mene looks
something like this :-
*********************************
| This | Cut |
| Area | Copy |
| contains | Paste |

| Bitmap | Exit |

Any suggestions?
