Crashes in MT apps can be nasty. Check this out: http://www.codeproject.com/debug/XCrashReportPt1.asp. One of the easiest ways to debug this might be to instrument your threads with logging - the thread id, module name, line number, etc. - using __FILE__ and __LINE__.

Hi All,
Thanks for your valuable inputs. I will follow the suggestions given.
Hopefully I should be able to nail down the crashing issue now.
Regards

Maybe someone mentioned this, but if you can get it to crash fairly easy, you can then attach the
debugger to the process and work your way back through the call stack (on any thread).
You don't need to be running in the debugger or have breaakpoints set.

good point!
heck even a crash dump will help  learn how to take a dump....lol it's potty training time!!! ...brings tears to my eyes, lil-jr is growing up 
you can always load the dump into your debugger of choice and work backward that way too!

I have created a small program that creates a 5 byte TCP packet to a server then the server sends it back. I'm unsure of how the wisock send and recv functions work exactly, does it just poll the connection until there is something in the buffer or is there an interrupt. I'm suppost to setup an interrupt, so any info you know or a good place I could find this info would be great!
Thanks
Simon

Interrupt handling will happen in the device driver level, not in Winsock or in the transport service provider that implements the TCP/IP protocol.

Default behavior of send(...) & recv(...) is blocking on the call till requested operation is finished.
Not aware of how this wait is internally implemented.
As an application programmer, I assume that you want to model your application so that it doesn't block on such calls and utilize the CPU cpu cycles for other tasks. If that is correct, you need to explore which I/O strategy we want to use:
http://tangentsoft.net/wskfaq/articles/io-strategies.html
Translating the "interrupt" to be the case where instead of blocking you want the program to be notified when data is there to read,
WSAAsyncSelect() can be an easy path to go as your app/window is notified through message loop.

I create SDI project that derive from CEditView (it look like NOTEPAD).
Then I create dialog project with some function that can open text file as well as show data of file in first project.I use ShellExecute() as
ShellExecute(NULL,"open","firstproject.exe","C:\\New Folder\\Text.txt","",SW_SHOW );
My problem is I can't open text file if that file keep in folder that the name including space charactor.
for example the above code
If the "Text.txt" keep in folder name is "NewFolder"(No space)it can open.
but if the folder name change to "New Folder" it will show Messagebox
"Access to C:\\New was denied".
Please give me some idea for solved this problem
|
|
|
|
|
Try this
ShellExecute(NULL,"open","firstproject.exe", "\"C:\\New Folder\\Test.txt\"","",SW_SHOW );
|
|
|
|
|
Thanks you but after I try
I got the Message "C:\New Folder\Test.txt was not found"
|
|
|
|
|
Have you actually checked that there is actually a file there with that name?
|
|
|
|
|
What about if I use variable for keep string?
<br />
void function(TCHAR m_szFile)<br />
{<br />
ShellExecute(NULL,"open","Firstproject.exe",m_szFile,"",SW_SHOW );<br />
}<br />
because m_szFile I get from DragQueryFile() function
DragQueryFile ( hDrop, 0, m_szFile, MAX_PATH ) )
|
|
|
|
|
You will still have to wrap quotes around the contents of m_szFile because it is a path that contains spaces.
|
|
|
|
|
Thanks a lot.
The problem already solve.

There's nothing wrong with the ShellExecute() statement. Look at how firstproject.exe is handling command-line arguments.

Can you tell me more about this sentence
"firstproject.exe is handling command-line arguments"
|
|
|
|
|
Such as?

I use App wizard create first project.exe, I don't know how the program work when I call it to open file.

Hi,
I have a doc/view app, main menu (IDR_MAINFRANE) and another menu (IDR_POPUPMENU1).
What i'm trying to accomplish is adding menu IDR_POPUPMENU1 as submenu to one of the
menu item in main menu.
I'm doing it in following way in OnUpdate():
<br />
CMenu csm;<br />
csm.LoadMenu(IDR_POPUPMENU1);<br />
<br />
VERIFY(pCmdUI->m_pMenu->CreatePopupMenu());<br />
pCmdUI->m_pSubMenu=&csm;<br />
and needless to say, it doesn't works...
can anyone help me out?
Thanks...

I use code from here[^] to merge two menus.
But I do TrackPopupMenu() with the result. This may be different, though the code claims it can handle top-level menus..
Failure is not an option - it's built right in.

Hi all,
I am having a dll with Dialog as a Resouce. I have created a Class for that Dialog also.
for example :
if Dialog Class is "one"
in the DLL Function
DLL Function()
{
one o;
o.DoModel(); // Here not populating the Dialog.
}
I then start debug the DLL. It is giving error in
BOOL CDialog::Create(LPCTSTR lpszTemplateName, CWnd* pParentWnd)
{
...
...
#ifdef _DEBUG
if (!_AfxCheckDialogTemplate(lpszTemplateName, FALSE)) --> here is the Error
{
ASSERT(FALSE); // invalid dialog template name
PostNcDestroy(); // cleanup if Create fails too soon
return FALSE;
}
#endif //_DEBUG
}
I am not able to Load the Dialog in the DLL. Please help me out.

before calling the function to display, you need to call the method AFX_MANAGE_STATE( AfxGetStaticModuleState();
|
|
|
|
|
Did you this code on the first line of your function
AFX_MANAGE_STATE(AfxGetStaticModuleState());
