For the ahadows check this http://www.codeproject.com/menu/shadowmenu.asp, tha flat look, well i'm working on that, but is really hard for me 
|
|
|
|
|
Some hints
- See the Fakemenu sample in an older PSDK dsitribution (emulates a menu, capturing mouse)
- In WTL, see http://viksoe.dk, for a flat (no shadows, but flat  ) sample.
- Generic
Set a Hook, once again, the WTL files show you how to set the hook and the magic number to detect the menu window (somewhere in CCommandBarCtrlImpl<t,...> , don't remember where)
Regards,
R.

I am using the following lines in function InitInstance() to associate file types to my application in a MDI architecture:
//Associate the file types
EnableShellOpen();
RegisterShellFileTypes(true);
The procedure is standard MFC and documented in many places.
When I double click my files with extension .spt the application is starting, but I am also getting the following system error message:
Cannot find the file "D:\VC++\MyApp\test1.spt" (or one of its components). Make sure the path and filename are correct and that all required libraries are available.
This message is wrong because the path and filename are correct. Could somebody explain what is happening?

I've had the same problem in the past when registering the same extension from different programs (or the same prorgam at different locations). Try looking for the occurrences of .spt and related identifiers (Spt.Document, stuff like that) in the registry and deleting them.

I know it has been a while, but did you ever find out what the problem was? I am having the same problem.

I'm using the following command in my program to close the CD Tray.
::mciSendString("set CDAudio door closed", NULL, 0, NULL)
But the problem is, after closing the CD tray the program is waiting for the CD to be read by windows (i.e. open a autorun file etc.). During this time the program appears to be hung. I was using the same API call in my VB version of the program. It did not have this problem. The app should only wait like this if I had used "notif" or "wait" parameters, right?
What am I missing here?

What is the reason to have most of ATL source code in .h files? Is there any disadvantage to having template functions in .cpp files? Can anyone point me to good articles on this topic?

IIRC, this is just so that the functions will be automatically inlined (where possible, of course).

You can't have template functions in CPP.
Now the standard does have the 'extern' keyword to provide the ability to place template functions in CPP files, however, nobody supports this element of the standard.

Meaning "Templated Functions"? So I cannot declare them in a CPP file, or I cannot specialize the template in a CPP file? I am asking because I am under the impression that specializing an STL template (like std::vector) creates templated functions (like vector::push_back), and while I do not do it personally (I use typedefs in .H files), I have seen code that specializes templates in CPP files like this:
<br />
std::vector< DWORD > vecDWORDs;<br />
<br />
vecDWords.push_back( 0xFF );<br />
vecDWORDs.push_back( 0xFFFFFFFF );<br />
Or am I misunderstanding you (or templates, for that matter)?
Peace!

Ok, let me clarify. What you can't do is define a template in an H file, then implement the methods of that template in a CPP file and THEN try to use those routines in another CPP file.
So, you can define templates in a CPP file just fine. But the methods can not be used in a second CPP file. That is why template methods are commonly found in the H file as inline methods.

OK, now I get it. I do not think I have ever tried that particular scenario, which explains my ignorance of it.
Thanks for clearing that up for me.

Is that 'export' or 'extern'?

DOH, you are probably right.
I'm getting old.
The mind is umm... what is it... umm... just on the tip...
What was I talking about?

I am trying to place on of these on a dialog, and it works (somewhat), but here is the interesting thing: the CHtmlEditCtrl class has a protected destructor(!).
Private and protected destructors force you to allocate an object on the heap (or by some other custom method, which I think is a bad idea in this case). OK, fine, I have it allocated off of the heap, but I cannot deallocate/destroy the damn thing, and it does not nuke itself when it gets it's DestroyWindow(...) method called (which is where most CWnd-derived classes that destroy themselves actually destroy themselves, so I leak that object!) 
Is there something that I am missing here? There is no exposed method that "self-destructs" the object. So I am at a lost as to explain why in the hell this thing has a protected destructor! 
Peace!

It's a weird thing, kinda shocks me too. For a quick fix, derive from CMyHtmlEditCtrl from CHtmlEditCtrl and use this instead. But this of course doesn't explain why the dtor was protected in the first place.

Hi,
I have a MFC program that I want to make it to take a path instead of a filename for its calling argument. Something like: AppName c:\docs\SupportFilePath
I noticed that the default action for having an argument in MFC program is it goes to Document::OnOpenFile(). Is there a way to prevent onOpenFile be called, but instead, get a hold of this argument in CMainFrame::CMainFrame()?
Here's what I've figured so far... Is the following an effecient way of getting a hold of the argument and passing it to CMainFrame??
(Inside CApp::InitInstance()
<br />
...<br />
CMainFrame* pMainFrame = new CMainFrame;<br />
if (!pMainFrame->LoadFrame(IDR_MAINFRAME))<br />
return FALSE;<br />
m_pMainWnd = pMainFrame;<br />
<br />
CCommandLineInfo cmdInfo;<br />
<br />
cmdInfo.m_nShellCommand = CCommandLineInfo::FileNew;<br />
<br />
pMainFrame->setCustomPath(cmdInfo::m_strFileName);<br />
<br />
ParseCommandLine(cmdInfo);<br />
<br />
if (!ProcessShellCommand(cmdInfo))<br />
return FALSE;<br />
What do you think?

I'd say this is fine

Hmmmm... I am under the impression that you need to call ParseCommandLine(...) first in order to populate the fields you are manipulating (like cmdInfo::m_strFileName)? Then you can change the m_nShellCommand value to prevent the app from opening the file...?
Peace!

I think you are right. I wasn't too sure what ParseCommandLine did. Thank you both!

Hi!
I have to calculate the number of characters an HTREEITEM of tree ctrl can hold. I am not sure what functions can help me with this. I would appreciate any suggestions on this.
Thanks,

A HTREEITEM is a handle to a tree item. Like all Windows handles, it is a 32 bit unsigned quantity. Perhaps you meant to ask something else?

Yes I did. I meant, the number of charaters each item(line) in a tree ctrl can hold. I want to calculate the number of characters that the tree ctrl can display on a single line.
Sorry for the confusion, I hope this is clear.
Thanks,
NC

Can you get the tree control's client area, take into account the item's indentation (get the tree item's label rect basically), and use CDC::GetTextExtent(...), or a similar function, to determine that? (Note, of course, that this will only get you a solid value if you are using a monospace font, like Courier New.)
Peace!

The text size of each column for a tree control entry is theoretically unlimited.
