To control the thread externally, i.e, from another thread, you can do a SuspendThread[^] on it after the specified time has elapsed.
This is not recommended in cases where the thread being suspended holds locks or synchronization objects.
In such cases you can send events to the thread to suspend itself.
But then the thread must be designed to handle such events.

One word for you; Redesign. Even if you succeed in creating that mess it would look horrible just opening 10K items in a menu, and a contextmenu at that.

Ignoring the fact if this is userfriendly or not, it shouldn't be impossible to create something like that.
With 100 hierarchy levels and 10000 items, it's not needed to have the actual 10000 items in the menu at the same time. You can add the sub items when their parent is opened, rather than adding everything at once.
e.g.
Visible menu:
File | Edit | View | History | Bookmarks | Tools | Help
That's 7 required visible items. Now when the user clicks on an item, for example Edit, you'd insert the appropriate sub items;
Undo | Redo | Cut | Copy | Paste | Delete | Select all | Find | Find again
Now you've added only 10 items, since you can ignore all the subitems under File, View, History etc.

I would suggest you have 9,990 too many. Nobody can possibly navigate that many items (nor would they want to) in a main window menu, let alone a context menu. Go back to the drawing board and re-think what you are trying to achieve.
I must get a clever new signature for 2011.

I hope that is a typo. If not there is something horrible wrong with your design. Having 10K menu entries is simply not the way to design an application. One word comes to mind, Refactor your design.

I take it there are tons of functions being called by these menu items that are technically the same, but are just applied on different data, with different options, in different modes of operation, etc.. Provided this is true, you should seriously consider all these entries to be replaced by a call to just one dialog box that lets you select all the extra parameters you need. Do that with all menu of your current menu items and see how many individual function calls you end up with - I bet it's less than a 100. If not then this is the most weird application I've ever heard of, apart from MS Word.

Please consider usability, especially when designing UIs.
I've come to understand that UI design is very involved and it is a winning factor between competing products.
You must first think if you yourself will use such a software.
In this case think of selecting a random menu item every minute.
Run that through your mind for some time and see if you give up using it.

Think the main rule is that if the user have more than 8 menu items to choose between, then you should consider redesigning the GUI.

Hi All,
i want a library/dll through which i can convert jpeg images to mpeg4 video format and vice versa.
i googled and found FFMpeg, many sample codes use the exe and do the conversions; i donot want that way, i want any library/dll to be linked to my project and then i will be using the api(s) directly!
Can you please suggest me any open source like or easier that FFMpeg?
Note i am doing this in VC++!
Regards,
Kapardhi

Generally a list control keeps two states of check box CHECK and UNCHECK
i want 3 states of check box in list control. Is there any sample to use more than one state of check box in list control?
how to do it?

Hello everyone, if the file csFilePath opened by other application. The statement, SHGetFileInfo() will throw exception. who knows how to resolve it?
SHFILEINFO sfi;
SHGetFileInfo((LPCTSTR)(csFilePath), 0, sfi, sizeof(SHFILEINFO), SHGFI_PIDL| SHGFI_SYSICONINDEX | SHGFI_ICON);
if (sfi.iIcon != 0)
m_ListCtrlLocalFileList.SetItem(i, 0, LVIF_IMAGE, NULL, sfi.iIcon, 0, 0, 0);
if(sfi.hIcon)
DestroyIcon(sfi.hIcon);

What kind of exception did you get (I see no exception mentioned in documentation)?

You have passed an invalid parameter in the third field, it should be the address of the SHFILEINFO structure, thus:
SHGetFileInfo((LPCTSTR)(csFilePath), 0, &sfi, sizeof(SHFILEINFO), SHGFI_PIDL| SHGFI_SYSICONINDEX | SHGFI_ICON);

when copy the code to the codeproject I delete this & signature.
But now the error dispear, after I set the sort property of the CListCtrl to none.
thank you for your reply.

Hi all
Recently, I learned how to split a window using CSplitterWnd and OnCreateClient.
In my application, I need different window layout (2X2 , 3X3)for different function modules.
function modules are invoked by clicking on a menu item.
I need to show different layouts when the use calling different function modules.
Thanks

This should work but I'm not sure.
Create 2 views initially.
In one do a 2x2 and in the other do a 3x3.
Now you can try to show/hide the parent view.

I am getting brave(r) in my old age in “pasting” libraries into my project.
(OpenCV does that to me anyway!)
What is a preferred way to include "external" files and link libraries?
Using compiler command line parameters / options or using #pragma ?
I am using both methods and getting rather confused when debugging the mess I create.
Comments?
In this case I'll make an exception – any comments are welcome.
Thanks for your time.
Cheers Vaclav

Always use compiler options, #pragma's aren't portable in any sense of the word. If you stick to command line options then you're reducing the amount of vendor lockin you have to cart about. In my experience it's far easier modifying a makefile (or making a new one for a new compiler) than changing a shed load of source files to cope.
Cheers,
Ash

To link in libraries, the header files that require the library use #pragma to include the library. I do not use compiler options since I do not want to include libraries that I do not need or might not need in the future if I no longer use a specific header. Another reason I prefer not to use compiler options is that I have had a lot of extra work porting Visual C++ to newer editions when some compiler options such as include directories were thrown out.
Note that you should also might use #pragma message to list libraries that have included when you set a particular preprocessor flag. This would make porting to another compiler that does not support #pragma easier.
When I do use compiler options, I use one of a few .props files with some project specific settings for things like preprocessor macros. I do not modify project settings via the GUI provided with Visual C++, except for a handful of options that do not load properly from props files.
