Re: Menu Control Popup using TrackPopupMenuEx

for the first problem: just call setforegroundwindow() before trackpopupmenu().

secondly if u r usig mfc, u can have message map entry for every command and if not then u trap the command in the wndproc().

enjoy

Ok I know that but cannot find how to do it?
I create my menu from a resource with id 350.
And here is my message map:

BEGIN_MESSAGE_MAP(CMyWnd, CDialog)
	ON_WM_CLOSE()
	ON_WM_SIZE()
	ON_WM_TIMER()
	ON_BN_CLICKED(152, ...)
	ON_BN_CLICKED(156, ...)
	ON_BN_CLICKED(171, ...)
	ON_BN_CLICKED(172, ...)
	ON_BN_CLICKED(173, ...)
	ON_BN_CLICKED(174, ...)
	ON_BN_CLICKED(175, ...)
	ON_BN_CLICKED(176, ...)
	ON_BN_CLICKED(177, ...)
	ON_MESSAGE(WM_USER_SHELLICON, ...)
	//<big>What should I write here to get menu messages?</big> :confused:
END_MESSAGE_MAP()

Thanks....

Typically ON_COMMAND and ON_UPDATE_COMMAND_UI are used for menus.

Yeah I have read a lil bit but I couldnt make it work...
I have tried a map

ON_MESSAGE(WM_COMMAND, Menu_Message)

also

ON_MESSAGE(WM_MENUCOMMAND, Menu_Message)

but still didnt worked! D'Oh! | :doh:

This is my function which I hope to handle messages:

LRESULT CMemorizerWnd::Menu_Message(WPARAM wp, LPARAM lp)

well in debug mode it never enters to my function.

So I am still looking for a solution for this... Unsure | :~

Maybe remove the TPM_RETURNCMD flag from the TrackPopupMenu() call
and use ON_COMMAND instead of ON_MESSAGE in the message map.

Also, you won't get the command message until TrackPopupMenu() returns.

Including methods in a DLL

Hi,

I have written a DLL to encapsulate the Winword interface which works OK but I would like to include all of (or maybe a sub-set of) the methods defined in msword9.h in my DLL without me having to write a wrapper for every method.

This is because I have wrapper functions for the most commonly used things but sometimes I need to do some other less-used thing and I end up having to re-build the DLL. For example I have a GetActiveDoc() method an I would like to be able to use this pointer to call any of the _Document methods.

Is there a way to force the complier to include all functions and methods declared in msword9.h in my DLL build?

Thanks

Tony Wink | ;)

I do not know whether there is any method provided by complier itself. In my project what I have done is added the whole power point class after importing them from the TLB file. You can get how to import all the methods from a TLB from CodeProject. Laugh | :laugh:

I think the simple answer to your question is no. However COM does allow you to do this sort of thing. I'm sure MSWord still exposes COM interfaces and it might be possible to aggregate them with your own wrapper object. In that case anything exposed by Word would be exposed your object. If this sounds like it might help then you'll need to look into COM aggregation.

Hi,

Thanks for the reply. Using COM sounds like a workable solution but I have not been able to find any documentation on this - not even in the Office development kit Frown | :(

Any ideas where I might find this information? Confused | :confused:

What you are trying to achieve is can easily be done in this way. My project is running fine.

Basically in your interface class you have to derive the classes in this manner.

class MyPPTApplication : public TOleHelper
{
// Operations
public:
LPDISPATCH GetPresentations();

}
This is just a hint how in my project I have achieved this for PPT.
In this way you have to get all the methods for Word, call the method in proper order & you will get the required result. GetPresentations does nothing it internally call this method

LPDISPATCH result = 0;
InvokeHelper(0x7d1, DISPATCH_PROPERTYGET, VT_DISPATCH, (void*)&result, NULL);

I do not know what is the use of you Dll, if it is to show the Word application then you have to create your own container object that is a whole big area in it's respect. WTF | :WTF:

Hi,

Thanks for the reply. The purpose of my DLL is to wrap the code that you have suggested so that I dont have to do this in my applications. Besides which, the msword9.h documentation is so sparse, I find it can take quite a while to figure out what objects i need, what methods to call and what the parameters mean.

For example, to insert a table into a document, you need need to get all kinds of objects (app, document, selection, range, table) and I dont want to have to do this each time I want to insert a table so I have a InserTable(rows, columns) method.

I guess I could still do what you proposed when I want to do the lesser used objects/methods, I could call them with InvokeHelper.

Thanks

how to show a button after move it?

tataxin24-Jul-08 20:26

I have a button on a list, something like whenever you select a row, move the button to that row. So I implement this in OnLvnItemchangedList event:

void CMyDlg::OnLvnItemchangedList(NMHDR *pNMHDR, LRESULT *pResult)
{
...
// canculate the rec by seleted row
CRect rec;
...

// move button
m_myBtn.MoveWindow(rec);
m_myBtn.ShowWindow(SW_SHOW);
m_myBtn.BringWindowToTop();

InvalidateRect(rec);
m_myBtn.RedrawWindow();

}

It works, but I cannot see the button. Confused | :confused:

If the mouse moves over the button, it shows then I can see it.
I don't know why, maybe there's something wrong in my last two source code rows. Can anyone explain how to solve this??

Thank you in advance !!

i downloaded a source code named mpeg2dec, but when i began to compile it i got such an error.
I am not sure why it occurred. The original project is a vc6 project. I use vc2005. So, who recognize this error and how to resolve it?
The original error is:
1>c:\program files\microsoft visual studio 8\vc\include\stdlib.h(592) : error C2485: '__restrict' : unrecognized extended attribute

Does it because VC2005 not support __restrict keyword?

Thanks

I would expect it to be the other way around, VS2005 to recognize __restrict and VC6 not to if anything.
Check that your source isn't intended to be compiled with GCC/glibc which makes extensive use of __restrict. As the error is showing in stdlib.h a standard header file I'm guessing something you've included before stdlib.h has messed with the Compiler by doing something like a #define __declspec or a #define restrict. I've only ever seen that sort of thing when someone is attempting to get cross compatibility with GCC. It's just a guess though, could be something else entirely.

Hi all,

I want to overload a function to do a simple processing. Only one argument is used in two cases, std::string variable and std::wstring variable. I want to try out it without overloading.

Took a tour in Google and I feel that there is a way to do using templates. I never work on with those. Can you guys give me a help. I just want to do a simple test. If I'm correct templates is a long section to completed.

Your help really valued to me.

Thanks

I appreciate your help all the time...

Thanks for the quick replay.

I found that in most of documents templates are define as follows.

template <class t=""></class>

So, what's the different with your answer and this?

By the way, can't I pass values by reference. I tried it and working fine. But give a warning there.

<br />
see reference to function template instantiation 'int <br />
GetString<std::string xmlns:std="#unknown">(T &)' being compiled<br />
<br />
        with<br />
        [<br />
            T=std::string<br />
        ]<br />
</std::string>

sorry forgot to include code tags in the post...correct code is

template<typename StringType><br />
void foo(StringType str)<br />
{<br />
    // Do processing here.<br />
}<br />
<br />
string str;<br />
wstring wstr;<br />
<br />
foo(str);<br />
foo(wstr);

you can pass by reference, use this code.

template<typename StringType><br />
void foo(StringType& str)<br />
{<br />
    // Do processing here.<br />
}
