When you say you don't know where to begin, what do you mean ? Have you used DX before ? Have you read the Crystal Space docs ? Joined the mailing list ? Played with the demonstration applications provided ?

I haven't used Crystal Space ( 3D is high on my gunner list, but below GDI+ as of a few days ago, so unlikey to happen soon ) but I'd suggest that while others here *might* know a bit about it, you're more likely to find meaningful help from the mailing list, which is full of people who are using it. I'm not suggesting it's wrong to ask here ( it isn't, at least not in my NSHO ), but just that your success rate could be higher if you also try the people who are all using it and discussing it's use.

Total memory crash when converting from regular to extension DLL

5-May-01 9:03

Hi!
I've spent quite a lot of time trying to convert a regular DLL into an extension DLL. The
problem is that the memory managment seems to be broken. The compilation and linking is warning-free, but when I start to test the application, I get all sorts of memory-related errors. Which errors depends on which features I test during the debugging session.

Error examples:
HEAP: Free Heap block 347fd0 modified at 348040 after it was freed
Acess violation when trying to write to normal variables.
_ASSERTE(_BLOCK_TYPE_IS_VALID(pHead->nBlockUse)); fails.

What do you think, have I done something bad in the DLL, or perhaps do I have some problem
which wasn't discovered when using regular DLLs?

Double check to make sure you are using the correct run-time library (Project Settings, C/C++ Tab, Code Generation Category). If your DLL is using a different run-time library than the application (or DLL) that is using it, you will get all sorts of crashes if you allocate memory in code using one run-time library and deleting it in another. Other than that, buy a memory checking tool like purify or bounds checker (which you should have anyway, well worth the money).

I've got the correct library versions, thanks anyway. I'm afraid a memory checking tool is out of the question since I am a student.

I can't think of any reason why going from regular DLL to extension DLL should cause any problems. Without a memory checker, you will have to debug it the hard way Cry | :((

. If you get stuck, email me your project and I'll throw it under bounds checker for you.

ctrl+break

5-May-01 8:43

I run console application with redirected input/output (to files) from GUI application via CreateProcess.
Actually, console isn't allocated and that application works in background mode.
How can I send Ctrl+Break messages to that application for stop running?
Confused | :confused:

Nothing like a specific question.....

I'm not sure what you want - is your game running in a window, or full screen ? Is it using DirectX or OpenGL, or is it just using standard Windows graphics stuff ?

Assuming you're running in a Window, you can catch OnSetCursor and set your cursor to whatever you want, based on any condition you desire.

Linking errors when converting from regular to extension DLL

4-May-01 19:22

Hi!
I when I tried to convert my regular MFC-dll to an extension DLL, I get

mfcs42d.lib(dllmodul.obj) : error LNK2005: _DllMain@12 already defined in CommonDLL.obj
mfcs42d.lib(dllmodul.obj) : error LNK2005: __pRawDllMain already defined in CommonDLL.obj
mfcs42d.lib(dllmodul.obj) : warning LNK4006: _DllMain@12 already defined in CommonDLL.obj; second definition ignored
mfcs42d.lib(dllmodul.obj) : warning LNK4006: __pRawDllMain already defined in CommonDLL.obj; second definition ignored
Creating library Debug/CommonDLL.lib and object Debug/CommonDLL.exp
Debug/CommonDLL.dll : fatal error LNK1169: one or more multiply defined symbols found

I found an MSDN-article, Q148652, about this, but it seems like that text, discussing CRT libraries, isn't applicable in this case.

Any idea's?

Solved. The cause of the error was that I forgot to remove AFXMANAGESTATE macros.

Trapping Escape key with dialog based apps?

4-May-01 11:22

Hi,

I need reminder or just a little help to trap the Escape key on the dialog based app to not close the dialog, instead use a button or the supllied menu item.

Thanks.

You can do that in PretranslateMessage, but I tend to put something at the top of OnCancel like:

if (GetAsyncKeyState(VK_ESCAPE))
return; // or do whatever else I want ESC to do

Hello, the codegurus around the world.

Paul DiLascia wrote his article about some similar situation.

Check here.
http://msdn.microsoft.com/msdnmag/issues/0700/c/c0700.asp

Someone asks Paul about "enter" key action to close the dialog box. Cool | :cool:

Have a nice day!

Override the OnCancel function like so:

void CYourDlg::OnCancel() {
	//override oncancel so we don't exit when they hit esc
}

In addition if you would like to catch the enter key you can override OnOK

void CYourDlg::OnOK() {
	//override onok so we don't exit when they hit enter
}

There is always the F1 key too which will search for a .hlp file which can be overridden by:

void CYourApp::WinHelp(DWORD dwData, UINT nCmd) {
	//CWinApp::WinHelp(dwData, nCmd);
}

(Notice this last one was in your App not the Dialog)

Hope this helped.

Given that it is a dialog box, my way is better - you don't stop the OK/Cancel buttons from working necessarily, but check if the Enter/Escape key is down respectively. That way the button works, but the key does not.

Christian

I've learned that you cannot make someone love you. All you can do is stalk them and hope they panic and give in.
