Bitmap dialog drawing problem

24-Aug-01 3:14

I have designed a class for win32 (not mfc) which takes a bitmap , makes a region of it and then draws that bitmap on the window canvas.(skin stuff)
I use a memory dc to speed things up.
However when i quickly move the window it still leaves prints behind.
I don't use any own code to move the window, i intercept the NCHITTEST message and respond with return HTCAPTION;
I have tried writing my own code for WM_LBUTTONDOWN, WM_LBUTTONUP, WM_MOUSEMOVE to allow tracking and moving of the window and then use SetWindowPos to actually move the window but this sollution leaves even more trails behind. I also capture the WM_ERASEBKGND message.

Any idea on how to speed it up? The only thing i can think of is not moving the window but showing a rectangle of the new window position when people are dragging the window. I tried something like that but got into trouble. I was using a hdc that i got via ::GetDC(NULL) since i need to draw on top of everything else then but i couldn't find a good way of deleting my previous rectangle.

I have looked at other samples for skinwindows but they al seem to use the same draw stuff like i do.

Does anybody have a sample program for this or know how to speed up the drawing without leaving a trail?

Thanks.

Visual Studio and stray files

John Hagen24-Aug-01 2:39

Ever since I installed one of the Service Packs for Visual Studio 6 I have been seeing stray files in my \Windows directory. For instance, one of them there today is "fffe09cd_{EBCCC94F-1148-4B95-8DC0-6FD293E98B0C}.tmp". It seems I get these everytime I reboot and they are not deleted unless I go do it myself.

Anyone know the story and how to stop these files from clogging up my directory?

Thanks!

DirectX and timers

24-Aug-01 0:52

Hi In my project, I need my app to "wake up" once a minute. Currently, I use a timer for this. It seems that when some games is running, the app fails to wake up. Can this be cause by some for me unknown DirectX-stuff?

It might be because the game uses *all* of the CPU, and your app doesn't get any CPU-time to do anything...

The problem is probably the game using DirectX's exclusive mode.

That's all I know - I don't know a better way to do it but I thought by suggesting that as a cause it might trigger someone else (or yourrself) to find a solution.

My version of MSDN says

"The exclusive (full-screen) mode does not prevent other applications from allocating surfaces, nor does it exclude them from using DirectDraw or GDI"

Is this outdated?

problem in CTreeView

24-Aug-01 0:48

I am working at tree view. My application is just like Address Book of Windows. I am using instance TV_INSERTSTRUCT to insert items in tree view. It works well in this way. I also save TV_INSERTSTRUCT instances for all items in array. After adding few items I delete all item at runtime and again inserts those item from array, which already have instance of TV_INSERTSTRUCT of previously, inserted and deleted items. But this time only first two items are inserted and all others are not shown in Tree view window. Can some body help me to solve this problem.

I agree you solution, but my problem is that the scrollbar (when displayed) is always disabled!
Can you tell me why?

Thanks.

a scroll bar in list box is disabled until it needs to be enabled, ie its enabled when there are mroe items in list box than the list box can show at one time.

ordering a STL - list of objects

Bernhard23-Aug-01 23:59

Bernhard

23-Aug-01 23:59

in my program i use a list of pointers to objects like this:

class object
{
public:
	int x;
	int y;
};

class A
{
public:
	std::list<object*> list_b;
};

now.. i do have got problems, because i should sort this list by object.x . i have tried to use te list::sort() function.. but it obviously doesn´t work, case the program doesn´t know how to compare this objects..
is there any member function i can override?
or is there any possibility how to use a set instead of that (would be perfect) ?

i am sorry.. i really tried to find a solution on my own.. but in all the docs and webpages i was searching in this problem seemed to be too obvious... so nobody ever told me how to do this

thanx in advance

Use the code below, just don't ask why it's done this way.

template<>
struct std::greater<object *>
{
bool operator()(const object* &lhs, const object* &rhs) const
{
return (lhs->x < rhs->x); 
}
};


// sort the list
std::list<object *> lst;
// ... insert objects
lst.sort(std::greater<object *>());

Need to strip zeroes from FP value

23-Aug-01 23:49

I am wondering if there is possibility to strip zeroes from floating point number using printf () function. I searched all printf options and didn't find any suitable one. Is there any other function convenient for this easy task?

Example: I have an array of doubles and I want to display them with .3 precision:

printf ("%.3f\n" f[i]);

Some numbers will look like 45.100 and some like 568.897. In case of 45.100 I want it 45.1 without trailing zeroes.

Well, your search quality isn't very good. Smile | :)

Use %.3g, 'g' instead of 'f' will strip trailing zeros.
