Hi
I am a d**khead!

I just realised that the shared hard drive on Machine_2 was not shared as "C", but as "Mikes C"

Changing my app to this has got it working!
Thanks for your help

I will check more thoroughly before asking again!

If Machine_2 is not "resolveable" then this will fail.

You can put the entry in your "HOSTS" file (Not really ideal)

or

You can put an entry in your domain's DNS server(s) and make sure it is the first DNS server the machines hit and "forward" unresolveable requests to outside DNS servers for those non-intranet thingy's like yahoo.com, msn.com, etc... (preferable for deployments as changing server IP's simply requires a change in the DNS entry at the server(s))

or

put the IP directly in place of the computer name in the UNC path (best for testing)

GetFirstView Position()

I have this:

<br />
POSITION rpPos ;<br />
<br />
rpPos = pDoc->GetFirstViewPosition();<br />
while (rpPos != NULL)<br />
{<br />
   pView = (CView1 *)pDoc->GetNextView(rpPos);<br />
}<br />

How do I know which View I am in? Is there any way
of displaying rpPos and knowing from that which view
I am currently in?

Please, any response any one can give me will be
greatly appreciated.

Sincerely,

their are several ways, see CObject::IsKindOf(...)

you might consider designing your own solution.

How does wanting to know what view is in a list have to do with designing one's own solution?

I meant eliminate the use of RTTI or CObjects version of it to identify the "type" of "view". My post was not clear at all, my bad.

Problem with termination of a thread

Hi,

I have an application, in which I run a thread when the application loads. This thread calls a certain function that initializes an array, and takes a few minutes to run. The thread works good, but if I close the application before the thread is done then there is an assertion.

How can I overcome this? Can I maybe force the thread to end if the user closed the application before it finished?

Perhaps in your OnClose handler you could have...

ShowWindow(SW_HIDE);
WaitForSingleObject(m_hThread, INFINITE);

Is the assertion a Debug only mechanism? What is the behavior in "Release" mode?

You will need to do 2 things to do this cleanly:

First, create an event and pass the event to the thread. Each pass of the Thread, use WaitForSingleObject with a low timeout value to see if the thread needs to exit (if it does, do any cleanup you need to and return from the thread).

The first step will allow the thread to exit cleanly. In your main thread, you will need to also add a WaitforSingleObject and use the thread's handle as the object. Use a timeout value appropriate for you (INFINITE is NOT appropriate here as it will deadlock your application's shutdown procedures). If the Wait times out, call TerminateThread with the handle for the thread (this is a forceful killing of the thread).

If you decide to become a software engineer, you are signing up to have a 1/2" piece of silicon tell you exactly how stupid you really are for 8 hours a day, 5 days a week

CString Array

Hi All

I am using a CString array which holds a list of ID's

for ex

arr[0]='37373';
arr[1]='37432';
arr[2]='37213';
arr[3]='37666';

i need to add an extra element to each array item

so my array would be something like

arr[0]='37373','fred';
arr[1]='37432','bob';
arr[2]='37213','june';
arr[3]='37666','alf';

what would be the best way to do this, and how would i go about it

thanks

Si

Do you mean

and

arr[0]="37373,fred";

?

You have to use some delimiter for adding extra data into each element of the array..like following.

arr[0]="43545" + "," + "mydata";
or use the Append method of the CString for each element.

Linking files - inline, or Dev studio?

Is it better to link .lib files using a line such as:

#pragma comment(lib,"XXXXXX.lib")

or, should they be linked via the project settings? What are the practical differences to these approaches?

Thanks, -mutty

they're easier to find, if you put them in the project settings.

I think there is no difference regarding the final executable, but I think putting of #pragma comment(lib,"XXXXXX.lib") in your files at least requires less configuration work when you re-use your code in other applications. You will not need to remember each time which external libraries must be used.

For instance, this practice can be seen in the header files supplied with MFC.

MFC Class Wizard has Stopped Working

Hi:

Does anybody know about this problem?

I have been developing this application for several weeks now. I've created all sorts of dialog boxes and used Class Wizard to create a CDialog based class for each one.

Since late last week, Class Wizard has simply stopped working. I create a dialog resource, double click it to invoke Class Wizard, the window pops up, I fill it out and press "Finish". Nothing happens. It does NOT generate the class files. No error is reported, it just doesn't do anything.

I am at a dead stop here. Is anyone familiar with this problem? Somebody suggested last week that I delete the NCB file. This is Visual Studio 2003. I do not see an NCB file in my project directory. I have tried deleting the ASP file but this has had no effect.

Thanks in advance,
Mark

I don't see a CLW file either. Perhaps that is the problem...
