I'm afraid not, but it's all in MSDN. Read the Bugslayer columns for a start.

If you want to catch exceptions coming out of the DLL function, you can do the following. However, if the DLL function is "extern C", you'll have to make sure you specify the /GX compiler option for your project.
try
{
MyUnsafeDLLFunction();
}
catch( ... )
{
AfxMessageBox( _T("The DLL function crashed :(") );
}
This should handle all exceptions coming from the DLL function.

I need to load and render an object from 3dmax(3dstudio) and show it as a 3d game.

The easiest solution would be direct-x9, but there's no support for 3ds files. However, there is a converter for 3ds meshes to direct-x meshes.
I did this once, it's straightforward.

Dear Zizilamoroso,
Thanks for your help,
Please send more information about this to me.
I want to show and move 3dMax(3dstudio) Files

If you want to load meshes into c++, I assume that you know how to program in c++. 
So, all you have to do is this:
- install dx SDK (min. 8, pref. 9)
- find the converter on the internet (it's called conv3ds.exe or simmilar)
- convert *.3ds to *.x
- there's an example on how to load those converted meshes (*.x) into c++ dx9.
btw. There're some helper classes in a common dir somewhere. You can do something like this:
<br />
pMesh->Load("test.x");<br />
pMesh->Render();<br />
Easy or what? 
regards

Hi, I have an MFC application with a COM interface. When I try to load a document when a call has been made to this interface, I get an assertion in OpenDocumentFile after AfxGetMainWnd() is called (wnd == NULL). I guess this call asserts because I called it from a different thread.
Anyone knows a (clean) sollution for this one?
|
|
|
|

To use OpenDocumentFile() from worker threads in ED (see sig) I post a message to the main thread which calls OpenDocumentFile() and then synchronize this with the worker thread. This is the only way I've found to do this sort of thing from a worker thread.

I was afraid that was the only way.

Doing anything much in any thread except the main one which has anything remotely to do with CWnd* and/or MFC Handle Maps is a real pain in the backside. I go through various hoops in ED to work-around these limitations.

Hexadecimal data are stored in a string(CString type).How can I
convert them to a Hexadecimal value?
LeonOrient
|
|
|
|

Use the CString.GetBuffer(CString.GetLength()) function to get the buffer of the CString and then use
unsigned long strtoul( const char *nptr, char **endptr, int base ); to convert the string to an unsigned long. After this, call CString.ReleaseBuffer().
The base for the strtoul function would in your case be 16.

_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

|
|
|

This is a difficult way. At first I think as you. But after a moment
I think that since this is a frequent convertion, so the Micro Soft
should offer a function to solve the problem.
What is the function? Can you tell me?
LeonOrient
|
|
|
|
|
A difficult way? 3 lines? 2 lines for preparing the CString and only 1 line to do the conversion? Not that much I would say...

_outp(0x64, 0xAD);

__asm mov al, 0xAD __asm out 0x64, al

----------------------------------------------------------------------------
_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
Could you tell me what the codes above can do with?
LeonOrient
|
|
|
|
|
Yes, I could. Have you tried it?
-Dominik
_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??
|
|

|
|
No, but I haver tried another way, it's very easy. Please look!
strText=m_lstWrite.GetItemText(i,j+1); //Get the CString: strText
sscanf((const char*)(strText),"%x",&temp); //convert,Only a sentence!
Of course, It's very nice to discuss with you.
LeonOrient
|
|
|
|
|
Well! BUT you use a const char * cast to get the char* from the CString. My solution with GetBuffer/ReleaseBuffer is safer.
If I would do it with a cast like you my solution would be:
strText = m_lstWrite.GetItemText(i,j+1);
temp = strtoul((const char*)(strText),NULL,16); Only one line of conversation code then too!

My god!
It is very good and very easy!
And it's also very regretful for me to say that and not to read MSDN carefullly after you gave me the tip.
Thank you very much!

A frequent conversion?
not for me... it's rare that I want to convert a string into a hex string of individual bytes. If I was writing hex dump programs, it might be.

I should use "not very easy" to replace "difficult".
Sure, it is a good way to solve the problem.
In addition, maybe we will program simply to find the endptr's value, do you think so? (  I am not good at using the function yet, maybe i am wrong again.)
Could you give us an example, please?
LeonOrient

Just use NULL for endptr

;PProblem: Convert CStrring to int. etc
We can use the function: atoi,atof,atol etc
LeonOrient

As far as I know atoi, atof and atol cannot read Hex strings
