That all sounds right.
What are the errors you are getting?
Peace!

Hi
I am trying to write a Context Menu extension and I'm having some problems with it. I need it to have MFC support as well. The extension works fine without the MFC support but everytime I include it, it just stops working. There are no errors, the registration works fine, all regkeys are set.
But the menu does not appear when I right-click on an item. However it did appear without the MFC support...
I have initialized MFC manually whenever I use an exported function. I don't know what the problem could be...
I would appreciate any kind of help.
Thx Zs.

Here is my problem :
I have a MainFrame (declared like any other WTL main frame). This
mainframe is creating child windows depending on user input (so at
runtime). There is nothing wrong then.
As far as I understand the child windows shares the same message loop
as the main frame (and I can verify this by printing the Thread ID in
any message handler).
It is becoming a little bit tricky now. Because I have too many child
window, the message processing takes ages to be done. So far so good,
I can create separate thread for the child windows.
So the mainframe's thread add its stack created the message loop to
the _module and run it.
The child windows' thread add their stack created message loop too and run it.
Great, it works, as long as I don't leave. When I quit the app, the
child are never destructed, and the main frame exists before the
childs (then, Winmain exits, etc)...
I don't want to add another thread just to handle the mainframe, so
how can I be sure that the child windows are stopped ?
I've thought about posting a message when a child windows exits the
loop, but this will not work as the main frame might already have
leaved its message loop.
Then I've thought about creating an event in the child window, and
setting it when the child window exits, but then again, this will not
work as the mainframe will not receive windows messages (if any
remaining) while waiting for events. Said differently, if the
mainframe miss a child window destruction, then the corresponding
event will be deleted, and the mainframe will wait indefinitively for
a never occuring event.
The only solution I could think of, would be to create a child window
event array in the main frame, and then spend some time to monitor the
events, and maintain the map.
I guess there is a easier way, but I can't figure it out.

Just don't do it....keep all your windows on the same thread....

What are you doing in your message handlers???? How many windows have you got???? Make use of worker threads to do non-UI work, but please keep all windows on the same thread...

Why are you saying this ?
Is there a reason for this or simply a "used to be said" rule ?
I can't create worker thread for non UI work, as it would require too many synchronization objects, etc...
|
|

|

Consider this....
Window A, owned by thread 1
Window B, owned by thread 2
In Windows A, you need to set a property of Window B, so you call SendMessage(WindowB, ....). In handling that message, Window B needs information from Window A. This translates to SendMessage(WindowA, ....). Result? can be deadlock, can be OK
You might think multi-threading with synchronisation objects is tricky. However, multi-threading with windows uses many *hidden* synchronisation points, so you can have latent bugs that are very difficult to detect. This link[^] highlights some of the pitfalls.
All I'm saying is that multiple windows owned by different threads are in general not the best design choice...

I need some kind of a "slim" combobox control. I want to use it for local edit in a listview control. Standard Windows' combobox cannot be resized beyond some minimum size.

hi!
i have written an activex control for MS Word that stores some binary data. now when after placing my control into word doc i store binary data (vary
between 25KB to 10MB). control persists it. when i close it and reopen the
document it is there. but when i place another control and store data into
it, the data stored into the first control is truncated, not the whole data
but only few KBs. i m using BSTR to store binary data using SysAllocStringByteLen. I tried to find out the reason but couldn't. Is there any
Guru to give me a hand. I am in too much tension about this problem.
Plz help me.
Thanks in advance.

 I using vc++ to create a console project that codes below:
The codes is according to some conditions:
1. sort elements count greater than SORT_MAX.
2. all elements is equal.
2. predicate 'greater' overriden pair of brackets to compare two elements, when two elements are equal that returns true.
#include "stdafx.h"
#include <afxwin.h>
#include <algorithm>
using namespace std;
class greater {
public:
greater()
{
}
bool operator ()(int x1, int x2)
{
ASSERT(x1 == 12); // There is aim to assert pointer over
if (x1 > x2)
return false;
return true;
}
};
int main(int argc, char* argv[])
{
// UINT arr[] = {12, 14, 31, 9, 6, 30, 11, 65, 30
// };
UINT arr[] = {12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12
};
int nSize = sizeof(arr)/sizeof(UINT);
greater gt;
sort(arr, arr+nSize, gt);
for (int i = 0; i < nSize; i++)
printf("%d\n", arr[i]);
return 0;
}
//////////////////////////////////////////////////////////////////////////////
// i'm debugging into for(;_P(*_F, _Piv);++_F) which in template function _Unguarded_partition, Why is infinite cycle here?
// i guess the problem has associated with above 1. 2. conditions.
template<class _ri,="" class="" _ty,="" _pr=""> inline
_RI _Unguarded_partition(_RI _F, _RI _L, _Ty _Piv, _Pr _P)

return (_F);

2. predicate 'greater' overriden pair of brackets to compare two elements, when two elements are equal that returns true.
This is the problem. std::sort expects a comparison predicate that implements what in techical terms is called a strict weak ordering[^]: your class greater violates (at least) the irreflexivity condition, i.e. when comparing an element against itself it returns true when it should return false. As you don't play nice with std::sort, this routine won't work.
In less technical terms, the comparison predicate must behave like the numerical < or > relationships do. In your case you have two options:Hope this helps.

I have gotten _Document pointer from withing my ActiveX control using GetContainer() function. it works fine for _Document object. now i want to access _Application pointer from this _Document pointer but couldn't. i am using following code.
CComQIPtr<MSWord::_Document> spDoc(pContainer);
ATLASSERT(spDoc);
MSWord::_ApplicationPtr spApp = spDoc->GetApplication();
ATLASSERT(spApp);
where pContainer is IOleContainer pointer which i got through GetContainer.
plz help me.
Thanks in advance

Hi
I wrote code using MS Visual C++ 6.0 and used different kinds of containers and algorithms from the STL. Can I take my code to be compiled and run in Unix without fuss?
Thanks!

Why not download GCC (which includes STL, IIRC) from here[^] and try it  GCC is the most widely used compiler on Linux/Unix, so this Windows version is the easiest to try!
You may have some problems - some parts of MSVC6 STL (and MSVC for that matter!) aren't compliant with the C++ standard. There's a few things in std::string that aren't right and all the member template functionss defined in the standard aren't member template functions in MSVC STL. However, there shouldn't be too many

STL is the Standard Template Library. It's part of the definition of the C++ language, so any correctly written code should work on all compliant implementations of STL.

To all the experts:
I would like to display an open-file-dialog by a click on the ellipsis button ("...") in the property browser. I have a simple ATL/MFC control and would like to give the user the possibility to enter the path to some file the control needs at desing time by clicking in the "..." button on the right side of the property name. Some stock properties like "Back Color" etc. have simliar functionality (they show a color picker instead of an open-file-dialog).
So what I really need to know is how to display something after a click in the "..." button.
I know how to activate the file-open-dialogs, so my problem is more the property/propety-page part.
I'd appreciate any comment since I have been searching for a solution in C++ almost one entire day

if your ATL is MFC enabled you can use CFileDialog Class and if your ATL is without MFC then [GetOpenFileName] api will help

Thanks for the answer, but I'm afrait, that was not my question.
I'm wondering how to implement an "..." button or maybe a whole custom property editor for my ActivX-Control (ATL 7.0 + MFC-Support).
So what additions do I have to make to a property, that my IDE (VB6, VB.NET) displays this button on the right side in the property browser?
