Hello *,
dialog boxes can have a question mark button in their caption that (when clicked) changes cursor and provides help for selected control.
I'd like to have the same functionality in the main window of the application, triggered for example by a toolbar button.
I guess a specialized message loop is needed to provide all the functionality (changing cursor, sending the WM_HELP, cancelling on ESC, ...) Is this piece of code avaiable or would I need to implement it myself  ?
One more thing - no MFC if possible, just pure Win32.
Thanks in advance,
Vlasta

This is what I would try,
When user clicks on '?' button:
- capture mouse to main window
- set flag variable that context help is active
In main window's WM_SETCURSOR function set cursor to question mark.
In main window's WM_LBUTTONDOWN:
- use ChildWindowFromPoint() to get the window clicked on.
- Post WM_HELP to that window
- Release the capture
- Clear the flag variable

Thanks for the reply, I was hoping somebody already did this. Oh well.

How do I query the settings in the Windows Properties Display Panel, e.g. to find whether normal or large or extra large fonts have been selected?
thanks in advance!

My first guess would be the Windows System Information functions like GetSystemMetrics(...), SystemParametersInfo(...), etc. Try starting with those functions in MSDN help, search and KB articles.
Peace!

Are you referring to the Appearance tab of the Display Properties dialog? If so, that information is stored in the registry at:

Does anyone know an algorithm that recieves an unknown amount of numbers(it stops when it recieves -1) and calculates how many of them are above the average without using an array, list, vector, stack, file ect.?
Is it even possible?

i'd say "no, not possible".
|
|
|
|
|
while number received != -1
store the number
end while
calculate the average
iterate through the array constructed below
if number in the iteration is above the average
increment counter
end if
end iterations
but the question is, WHY don't you want to use the STL ??
managing your own memory with such growing arrays are not good things to do by yourself...

While you can certainly compute the average without any additional storage, you'd still need to be able to go back through the set of numbers to pick out those greater than the average.
Just for our edificaton, why the restriction?
Is this your post, too?

why does that matter?
the original post said "no arrays".
|
|
|
|
|
because even if "iterate" is not the correct word, he can still traverse the array he'd have built...
|
|
|
|
|
he said 'no arrays' which I think means no arrays not iterators

sorry, don't get you...

You just can't use arrays!
You have no array at the beggining, the user writes for you the input number by number-NO ARRAYS!

WTF !!
even if you had a console program, by which the user typed all the values in a single line, you could still create an array (or an STL container), parse the string to extract the values, and store them then...
if you don't explain your problem exactly, how can we guess what you're doing ?
|
|
|
|
|
the problem says that you mustn't use arrays or other allocation of memory.

then, no chance to resolve it 
|
|
|
|

You say that there is no chanse to resolve it so can you prove it mathematiclly?

i'm tired with your thread... go find someone else to bore

Do you have any idea about it?
