(1)Note that the background is not filled when the CMFCButton::m_bTransparent member variable is TRUE.
https://msdn.microsoft.com/de-de/library/Bb983413.aspx

(2)SetFaceColor() is ignored by modern theme engines. The wizard greates something like:

CMFCVisualManager::SetDefaultManager(RUNTIME_CLASS(CMFCVisualManagerWindows));

You can comment this line out to disable custom MFC themes. This works, but the button
will not look good because of classic theme.

Possibly you can Load a Color-Bitmap to get the color you want.

Another solution would be to do an ownerdraw button - handling the OnDrawItem() or WM_DRAWITEM
message and do the painting yourself.

There is no need to store mWindowTitle, mWidth and mHeight at all. They can be easy accessed over mHwnd.

For several Windows it would be better to store mHwnd as a vector.

Have the Invaders a strategie, do they come down per random or something else ?

You can do all that in AnimateAlienBullets; just write a AlienMove() Funktion and add it below "case '@':"

You are far away from your initial question. Please close this Question, dont forget to vote.

If you have new Questions open a new Question and show your actual code. Bye.

1. The Levels ARE implemented, just add it to the menu yourself (its your work,easy)
2. You can add a Timer like this:
// Create a waitable timer.
HANDLE hTimer = CreateWaitableTimer(NULL, TRUE, "WaitableTimer");

LARGE_INTEGER liDueTime;
liDueTime.QuadPart=-100000000;

// Set a timer to wait for 10 seconds.
SetWaitableTimer(hTimer, &liDueTime, 0, NULL, NULL, 0))

// Wait for the timer.
WaitForSingleObject(hTimer, INFINITE);

Note that no Errorhandling is included, but should be!
3. Cant belive that my gotoxy does not work for windows, if you have
another OS you have to look for a solution for that.

By the Way - what Compiler and OS do you use ? My code is testet with VisualStudio.

What is the problem to change the position of the Invaders ?

Just delete it at the current position an redraw on a neigbour position.

You should post the code with code-tags.
The Funktion game() is missing. ClearScreen() is not defined. After inserting a simple
ClearScreen() and an empty game() the screen is flickering.
Its no good idea to clear the screen without need - just draw the differences.
I would also suggest an function drawgame() to draw all the stuff.
The menu should be coded with switch case.
main should call menu. The menu should also be displayed when leaving
the game e.g. ESC-Key should work.

You are right, something is wrong with the shift. But your comment does not catch the facts.

He tries to shift 176 Bits, converted to hex-text into a 50 char output buffer.

Both datatypes are to small for this action. See Solution 3.

value: 11 * 2 * 8 Bit = 176 Bit

formatString: 2 + 44 + 10 + 1 = 57 chars

The shift is strange and the buffer to small.

merano 7-Mar-14 17:59pm View

You need at least 57 chars for output buffer, but before that you need

11 * 2 * 8 Bit = 176 Bit datatype for value, but i think there are only 64 Bit.

The shift is strange.

ourStruct args[Chunks];

for (j = 0; j <= numOfChunks; j=j+2) {
rc = pthread_create(&thread[0], NULL, Method_Encryption, &args[j]);
rc = pthread_create(&thread[1], NULL, Method_Encryption, &args[j+1]);

The Field args has to be bigger (not equal) than numOfChunks because of [j+1]
Cant see where numOfChunks is calculated.

1048575 = 0xFFFFF Means everything is supported.

Did you try waveOutGetDevCaps() ?

merano 13-Nov-13 14:12pm View

Did you check the Capabilities ?Here are some more hints:

http://msdn.microsoft.com/en-us/library/windows/hardware/ff536383.aspx

WAVEFORMATEX is sufficient for describing formats with sample sizes of 8 or 16 bits,

but WAVEFORMATEXTENSIBLE is necessary to adequately describe formats with a sample

precision of greater than 16 bits.

merano 12-Nov-13 16:19pm View

The waveformatextensible is working here. Where is the exact error line ?
Do you get an Error Code or Message?

merano 11-Nov-13 18:50pm View

What is the Problem with your code ? Do you get Compiler-error ?
Can you post essential code snipet ?

merano 8-Nov-13 19:59pm View

Perhaps you have to handle OnCtlColor() and OnEraseBkgnd()

Here is a Example for the MFC-Way

Solution 1 is based on CLI code - you need .NET
Nothing of this is usable for C++ and pure Win32 API.

Google says: You don't need to call x264_nal_encode because x264_encoder_encode return already encoded nals.

This Solution does only support a-s-d-w keys no arrow keys, why ?

Here a solution for that:

case SDL_KEYDOWN:
keypressed = event.key.keysym.sym;

// ##########################
// support arrow keys
switch(event.key.keysym.sym){
case SDLK_LEFT:
keypressed = LEFTKEY; // alternate SDLK_a
break;
case SDLK_RIGHT:
keypressed = RIGHTKEY; // alternate SDLK_d
break;
case SDLK_UP:
keypressed = UPKEY; // alternate SDLK_w
break;
case SDLK_DOWN:
keypressed = DOWNKEY; // alternate SDLK_s
break;
default:
break;
}
// ##########################

What do you mean with "Static DLL" ?
Did you link MFC static ?
You should not link MFC static for a DLL. You are never shure what Version
the Main-application is running with.

merano 5-Feb-13 18:17pm View

This member does only use the parameter max what about x and y ?

Not able to figure out why you think you need two for loops.

when you calculate the fillpos you can fill with 1 pixel wide sprite

with one for loop

fillpos = (fill * 128)/(max -min);

for(int i=0; i<fillpos; i++) ...

Managed C++ says that it should be CLR

The first Ref is Win32 or MFC. Code is not UNICODE - see also comments.

merano 2-Feb-13 5:10am View

Works perfect if only replace lea for adresses, not for e.g. ARRAYSIZE

<asm>
GET_ARRAY:
__asm {
// Get values in arr from the user
// Run Merge Sort on the array
lea EAX, arr //instead of mov EAX, arr
lea EBX, temp_arr //instead of mov EBX, temp_arr
mov ECX, ARRAYSIZE //ARRAYSIZE (no lea!)
call Merge_Sort
jmp finish
}
<asm>

You get 5 from me!

Read MSDN plase: Typical buttons are the check box, radio button, and pushbutton. A CButton object can become any of these ...

http://msdn.microsoft.com/de-de/library/yf1wax6c

Your Solutions are based on Ownerdrawn Buttons, not compatible with modern GUI.
The "Enhanced Colored Button" from codeguru does work, but its quite old (from 2004)
and does probably not comply with newer requirements.
Another Problem is, that your Solution needs additional header and cpp files not
from Microsoft. I suggest using MFC-Classes supported by Microsoft to solve.

merano 31-Jan-13 16:52pm View

Only owner-drawn CButtons respond to the parent window processing the WM_CTLCOLORBTN message.
http://msdn.microsoft.com/en-us/library/windows/desktop/bb761849
In this case you have to draw the Button yourself.
See Solution 4 for easier way.

The C++ Language does not include Graphics. If you want to code this Functions you have to use System-Calls or a Library that covers this.
When you do not want to use " third party libs" you have to use System-Calls or Librarys that come with the Development Environment. If you use Windows with Visual-Studio you could use GDI for Example, for Unix you have to go other ways.
