Does anybody know how, or if it is even possible to display tooltips on a dialogue based application. I have created a toolbar and would like tooltips to appear when the mouse is held over the buttons. I would appreciate it very much if someone could help me with this problem, cheers.

Hi ALL,

I have created an Ole Control with property pages, and it's a good bit more complicated than that... I derived my own property
page from COlePropertyPage.
Everything is allright untill i wanted to hide the propertysheet buttons (Apply, OK, Cancel) which contains my propertypage.

I write something like that in the COlePropertyPage derived class,

...
CPropertySheet * pps = ( CPropertySheet * ) GetParent ( ) ;
pps->GetDlgItem ( ID_APPLY_NOW )->ShowWindow( SW_HIDE );
pps->GetDlgItem( IDCANCEL )->ShowWindow( SW_HIDE );
pps->GetDlgItem( ID_APPLY_NOW )->ShowWindow( SW_HIDE );
...

but the application crashes.
i want to have a solution for this issue.
Need help.
Hajer.

Pls help

Thanks in advance

Hello,

No. You rename the DLL and change the CLSID in file ( using GUIDGen tools in Visual c++) and recompile it. Then your CLSID Changed.

With Regards,

Hello Selvam,

Thnks for the reply.

Yes i used uuidgen tool to get the guiid and changed in the IDL file..
The renamed DLL gets registered but it doesn;t work...the program just exits..

Pls help...

Context Menu Handler

I am not sure whether I posted at a very unfavourable time and my posting vanished behind several questions posted later - or if I did not make myself clear enough to be understood. I might even have violated some rule I am not aware of. Anyway, I will quote my previous post. If you have even the slightest idea how to fix this, please drop a few lines.

Thanks in advance

Quoted post:
"Hello everyone,

I've got quite some problems with programming a Context Menu Handler in
Visual C++ (6.0, SP5) under Windows 2000.

[...]

Until now, I only wrote basic C and some more advanced Java Code. A few
days ago, I received a new project:

I should create a context menu entry (submenu with 2 or more menu items). Selecting one of these entries should start the corresponding application.

I read several "Context Menu"-Pages until I found out that, in order to have a sub-menu, I would have to write a COM-DLL, a "context menu handler".

[...]

Reading on that topic in the MSDN did not help me much, as I have not programmed (in the?!) COM yet.

I then stumbled upon Michael Dunns "The Complete Idiot's Guide To Writing Shell Extensions" and downloaded his example projects.

Well, it did not work. The example projects were compiled (0 errors, 0 warnings), registered (regsvr32 dllname -> Registration Successful) and written into the registry (shellex->ContextMenuHandlers), mostly as scripted in the RGS-File of the project.

I tried several of the example projects, none worked. The context menu - even though the handler is registered for the filetype - does not change or give the desired new options.

I am a local administrator, but I even wrote the GUIDs to the APPROVED section as described in M. Dunn's first chapter. Well, they still dont work, and I am pretty much *censored* since I can not get it to work.

I do have absolutely no idea what causes the failure, I did not change any of the example projects.

Can someone please help me?"

Greetings from Germany
Sebastian

Logging off and back on (to restart) Explorer should make the menu items appear

Thanks, that worked for your BMPView Example.

But it did not for the OpenWithExt-Example, which does not compile correctly.

OpenWithExt contains the following code, which generates an error:

// Insert the submenu into the ctx menu provided by Explorer.
MENUITEMINFO mii = { sizeof(MENUITEMINFO) };

mii.fMask = MIIM_SUBMENU | MIIM_STRING | MIIM_ID;
mii.wID = uID++;
mii.hSubMenu = hSubmenu;
mii.dwTypeData = _T("C&P Open With");

InsertMenuItem ( hmenu, uMenuIndex, TRUE, &mii );

return MAKE_HRESULT ( SEVERITY_SUCCESS, FACILITY_NULL, uID - uidFirstCmd );

Obviously, Visual Studio 6 Enterprise (thats what we are using) cannot resolve
MIIM_STRING. If I fire up the MSDN, there is no MIIM_STRING for MENUITEMINFO.

Is that a typo or did I do anything wrong?

I am curious because this "Submenu-Example" is pretty much what I need to implement, with a few lines of additional evaluation code and multi-file-support.

Cheers
Sebastian

It sounds like you're using old header files, install the Platform SDK to get the latest. More info is in the C++ FAQ (see my sig)

Using stable_sort with predicate function: Help please.

Cloaca8-Feb-04 19:36

Hi everyone,

I have a class like this:

// Header file
class CFoo
{
public:
	CFoo();
	~CFoo();
	BOOL SortByName();
	// Other functions declared here...

protected:
	std::vector<CRec*> m_Recs; // CRec is a class with CStrings, etc.

private:
	struct NameComparer
	{
		bool operator()(const CRec* A,const CRec* B)
		{
			return ((A->m_strName) < (B->m_strName));
		}
	};
};


// CPP file
// Other functions are defined here...
BOOL CFoo::SortByName()
{
	std::stable_sort(m_Recs.begin(), m_Recs.end(), NameComparer());

	return TRUE;
}

Now, basically, I am trying to properly write and use a predicate function (I think that's what they're called; please correct me if I'm wrong) in the context of calling std::stable_sort (and just std::sort for that matter). There are many helpful examples around, but they don't seem to cover dealing with a non-trivial class (or if they do I haven't 'gotten it' yet).
In my case, I want to be able to sort the vector of CRec's according to several different CRec member variables (different CStrings, ints, doubles, etc.). My questions are:
1) Did I use proper coding techniques to solve the problem as I have shown here?
2) Is it the case that I need to add additional structs under the private section of CFoo for each comparison CFoo member function I want to write (with the comparisons applied to the std::vector m_Recs and based on the CRec members themselves actually)?
3) Why do I need to wrap the comparison functions in a struct? How does that fact relate to operator(), etc.?

Thank you all again for reading and giving any advice,
Best, Smile | :)

Eric

How to delete CFileFind Object

9-Feb-04 5:47

It's easy to make the "All" line the first item in the list, but I do not know of a way to ensure that constraint in the presence of scrolling.

I am sorry but it was really silly mistake and if I add I will get too many comments on that …
The mistake was that I was using the same public CFileFind object in two function in each one I use this object and close it once time in the main after I call both so I add the close function in each fun
I really do not mean what you said

If the comment you receive is from a professional, it would probably have something constructive in it. Otherwise, if the comment was laced with this-is-crap, what-were-you-thinking, and isn't-it-obvious remarks, you can ignore those anyhow as they serve no other purpose than to humiliate.
