Automatic Demonstration Capability - ideas?

Hi there
I would like to add a Demonstration feature to my Visual C++ application. For example the user would click the "Demo" menu item, this would start executing a script and move the mouse, click buttons, display tooltips, that kind of thing.

I'm sure I've seen it done in some applications before but can't remember where. Has anyone ever seen this sort of thing before, or any ideas where I could find such a thing?

It would be so useful for me and I'm sure many others.

Thanks
[d3m0n]

Usually it's a movie. A product like powerpoint should allow you to prepare a demo
that you could run from your product.

Thanks, I've looked into using Powerpoint, but having bitmaps and animation is not as memorable as seeing something actually happen inside your program.

If I could only remember where I've seen this before.... D'Oh! | :doh:

Using _T() and L&quot;&quot; in UNICODE Projects? [modified]

Hello community,
have one question about L"" for unicode strings:
do i have to use this L"" for strings always, even if is only one caracter length,
also, if i have an single character to compare, something like this:

('H' == *lpsz) // lpsz is an LPCTSTR loaded from an CString
//or to use
(L'H' == *lpsz)
// and 
("H" == *lpsz)
//or to use
(L"H" == *lpsz)

to often my application breaks in this line:

// original code, my program breaks here sometimes:
while( (*wcStrToAnalyse != '\0') && (*wcStrToAnalyse != ' ') )
// i want to loop through this string before i find an first space or string end

and my project is in unicode.
thanks in advance
break;

if you're using LPSTR (CHAR*) strings, then don't use any.
if you're using LPTSTR (TCHAR*) strings, then use _T().
if you're using LPWSTR (WCHAR*) strings, then use L.

Debugging a dll project!

Ok, here's the deal. I have several dll's that call each other. Now I would like to debug them to know what they're doing and understand their flow. How do i do it? Unsure | :~

do you own their sources or not ?

moreover, to debug a DLL, it must have been compiled in debug mode (otherwise, no chance to do that).

then compile all in debug mode, and set a breakpoint where you want it to stop.

debug just as if it were an exe...

Best go for a tree view which gives lot more features and flexibility. Or
else explain ur scenario more elaborately. Like u need sub groups like folder view in explorer or something else.

treeview seems good.

but explaining this in English (no SMS) is better so that everybody can understand your post Wink | ;)

Where Does the Extra Thread Come From?

Cliff Hatch4-Dec-06 23:42

I'm working on an application that launches a separate thread for some processor intensive activities.

I used Spy to look at the running application, expecting to see two threads - but there were three! I can make out the main thread and the one that I launched. Both these clock up CPU time as expected. The third thread doesn't appear to do anything - CPU time etc. stays at zero.

The application works fine - I'm just curious to know where the extra thread comes from. I assume the system creates it automatically for some purpose. Does anyone know what it might be for?

Best Regards

Debug your application and halt it after your second thread is created and it has ran for a while.
Switch the context of the unknown thread and have a look at the bottom of the call stack.
Does it say something with 'RPC'?

Thanks for the suggestion Roger, but I'm having difficulty following your instructions.

All the threads close down cleanly when I halt - I assume you mean "pause"?

How should I switch the context of the unknown thread? The number of switches increments when I refresh the Spy properties window - is this what you mean?

I don't see how the call stack or anything else will be affected when the application is paused.

Apologies for this - I think I must be completely mis-interpreting your suggestion - could you provide some clarification?

Best Regards

Cliff
