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

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.... 
Cheers

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)
(L'H' == *lpsz)
("H" == *lpsz)
(L"H" == *lpsz)
to often my application breaks in this line:
while( (*wcStrToAnalyse != '\0') && (*wcStrToAnalyse != ' ') )
and my project is in unicode.
thanks in advance

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.

Hello,
thanx for help,
is this for single characters to, like this : 'H' or _T('H'), 'H' or L'H', "H" or L"H"?
Sorry about this question, but i need help!
regards

yes, this is also extended to single characters

Be carefull with '' and "" ... can drive you into some problems.

are you suspecting me to confuse characters with C-Style Strings ?

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?
|
|
|
|
|
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).
|
|
|
|
|
Yes I have all the sources. Its a VC++6 Dll projects.
|
|
|
|
|
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 
thanks

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

:-> Ummm, terminology stuff... Yes, I meant "pause", otherwise the rest of my suggestions would not be of any use.
Find the menu option 'Threads...', in VC6 it's under the 'Debug' menu.
Inside the small thread window you can choose which thread you'd like to see the context for. As I understood it there will be three whereas you'll recognize the top of the call stack for two of them since it most likely will be your own code. The third is the unknown and it would help a lot if you can provide information about the call stack for that thread.
Cliff Hatch wrote: I don't see how the call stack or anything else will be affected when the application is paused.
Of course the call stack won't change during the application pause, but the contents of the call stack are important: what's at the bottom and what's at the top of the call stack.

No worries!

Many thanks for this Roger.
I didn't know the "Threads" window existed. I found it under "Debug", "Windows", "Threads" in .NET 2002, and suddenly your original post makes perfect sense. 
The unknown thread has the generic sounding title "Win32 Thread", and the call stack contains just two entries:
ntdll.dll!7c90eb94()
kernel32.dll!7c80b683()
I'm still curious about what it does, but it is clearly a system thing (see also reply from David Crow below). I'm happy to accept that - and even happier to have discovered a new Visual Studio feature along the way. 
Best Regards
Cliff

The other thread could come from code other than yours. For example, use Task Manager to watch Visual Studio's thread count. Now open a file, and watch the thread count increase by several.

Thanks David
Yes, I see the thread count changing. There seem to be a number of short-lived threads in addition to the persistent one I noticed.
Best Regards
