put the template in a .H file and let anyone who wants to use your template #include that .H file.

good afternoon,
The memory leak report looks like this:
{404} normal block at 0x00FD8CD8, 49995 bytes long.
Data: < > 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20
{399} normal block at 0x00FD8770, 1309 bytes long.
Data: 48 65 61 64 65 72 20 4C 65 6E 67 74 68 3A 20 30
{166} normal block at 0x00FBDAC0, 14844 bytes long.
Data: <5 a p > 35 00 00 00 90 D2 61 00 70 81 13 00 00 00 00 00
c:\dev\c++\billing\voldisc\voldiscdlg.cpp(592) : {147} normal block at 0x00E25028, 64 bytes long.
Data: < > CD CD CD CD CD CD CD CD CD CD CD CD CD CD CD CD
the Last part with all CDCDCDCDCDC seem like unintinized object, but it looks alright in the code,
DiscountData = new DISCOUNTDATASTRUC;
what about all the 20202020202020, it has 49995 bytes long.......is it the leak size? this application works, but it has all the memory leak..
thanks.

Right, it is an uninitialized object and is used for debugging purposes. You can see it, and others, in dbgheap.c. Initialize all of your pointers to NULL.

thanks for your reply,
"it is an uninitialized object and is used for debugging purposes", do you mean this should not effect the release version of the program? it seems like stop and didn't create the report when I ran debug version ....

If you can run the program in the same exact way, you can put this:
_CrtSetBreakAlloc(404);
in the beginning of the program (where 404 is the number in brackets above) to get the program to break when it allocates the memory that doesn't get freed. I put mine at the beginning of my app's InitInstance. That might tell you something; I've found it to be a very useful tool. But like I said, it needs to be run in the exact same way so that the number doesn't change.

thanks for the command, I have tried this tip on my APP's InitInstance, it stop at the DBGHEAP.C, when I look at the call stack, it hit this part of code int nResponse = dlg.DoModal();, and the least are MFC stuff......couldn't really tell where it cause the problem
it brought up another question, all the numbers inside {}, some of them are connected next by each other, like 191, 192, 193, is it means one uninitized pointer causing couple crashes or something like that? I don't really know how to read this. thanks again!

Just double click on the "c:\dev\c++\billing\voldisc\voldiscdlg.cpp(1169)" line and it will take you to the leaky object.

Hello gurus,
I'm currently rewriting a 20 years old 2D game. The game I rewrite is BubbleBobble for the TI-68K platform in standard C (C99). I ask my questions on this forum because it might interest other people and I don't know where to find the answers.
I would like to know where I can get information about old fashion 2D games programming for the following things:
- Physics of sprites:
* Jumping of sprites with detection of elements of the map (player, ennemies and bosses)
* Collision detection between sprites of different natures and sizes (player/ennemy/bubbles)
* Collision detection with the elements of the map (mainly walls)
- AI:
* Tracking algorithms with path-finding: that is ennemies follows the player and avoid obstacles when encounting them
* sentinel movements
Thanks in advance for the help.
Best regards.
There is no spoon.

you have to make a sprite manager for sprite collision, etc...
buy a book something like Game programming in 24h or lesson it`s a good book of 2D game programming

There are lots of game programming sights on the net that have tons of code for doing every thing you are looking for.
Some good keywords to search for: Graphics, Gems.
"Graphics Gems" are a series of books on graphics algorithms, and the code is online.
There's also another series of books with "Gems" in the title that covers: graphics, AI, collision detection, sprite management, ect...

If the answer is yes, could anybody tell me how to do it please? And also how to connect with mysql database in a MFC application please?

Yes, you just wouldn't be able to test it effectively.

Create a DSN and then look at the MFC classes CRecordset and CDatabase, or the ODBC API if you are not using MFC.

I'm trying to set up info tips for different subitems in a CListView in Report mode. I can catch the LVN_GETINFOTIP when you hover over subitem 0, and correctly display the text I want. But hovering over any other subitem doesn't produce the notify. It would seem that the method CListView::SetInfoTip might do what I want, but it fails (returns false) when I invoke it, and I have no idea why.
I have an application manifest, and I am using version 6 of ComClt32.dll. I've set the extended style to include LVS_EX_INFOTIP.
I'd like to get this API working. Alternatively, if there's some way to get the LVN_GETINFOTIP notify when hovering over a different sub-item, that would do it too.
thanks,
Stache

The docs say that LVN_GETINFOTIP is only generated for the first item.
As for SetInfoTip, make sure that you are using a wide string. I had the same problem only to find out later that I was passing a ANSI string when it expected a wide string.

Ok, I think I've done all the manifest stuff correctly. DLLGetVersion on "comctl32.dll" reports Major Version 6, Minor Version 0, Build 2900, Platform 2.
Here's the actual code fragment, since at this point, I think I must be missing something blindingly obvious:
LVSETINFOTIP sit;<br />
sit.cbSize = sizeof( sit );<br />
sit.dwFlags = 0;<br />
sit.iItem = 1;<br />
sit.iSubItem = 1;<br />
sit.pszText = L"fake primary info tip";<br />
<br />
CString str = m_ListCtrl.GetItemText( 1, 1 );<br />
<br />
BOOL bResult = m_ListCtrl.SetInfoTip( & sit );
The extended style includes LVS_EX_INFOTIP and LVS_EX_LABELTIP, and I've tried either, both or none with no difference in results.
Any insight would be greatly appreciated!
thanks,
Stache

Hi I need to write a small console application that goes through all the entries and appends a character to the caption of every resource id string. Does anyone have some sort of example that could be useful or anything else that could help me get started?? Libraries I should use to read a an etry from a table might help. ok thanks

Given the following format:
STRINGTABLE PRELOAD DISCARDABLE
BEGIN
ID1 "GymScores"
ID2 "Ready"
END
STRINGTABLE DISCARDABLE
BEGIN
ID_INDICATOR_EXT "EXT"
ID_INDICATOR_CAPS "CAP"
ID_INDICATOR_NUM "NUM"
ID_INDICATOR_OVR "OVR"
ID_INDICATOR_REC "REC"
ID_INDICATOR_ITEMCOUNT "9,999 items"
ENDYou would need to read each line of the file until you find a line starting with "STRINGTABLE." Skip the next line that starts with "BEGIN," and process the next N lines until you encounter one that starts with "END." Since there can be multiple STRINGTABLE/BEGIN/END sections, you'll need to do this in a loop. Make sense?

I want to create a file mapping object, map it writable to a view and write some data to the shared area, and then give the file mapping object to the clients for read-only. To be able to first write to the shared area, I have to use PAGE_READWRITE with CreateFileMapping, but with this the clients can call MapViewOfFIle with FILE_MAP_WRITE and write to the shared area.
Any idea how I can avoid create a file mapping object and still write to it once and only once?
Thanks for any ideas.
