Hi,
I'm all out of ideas,
I want a lump of eye-candy for when my dialog app is downloading data etc,
Something more exciting than an AVI control,
But still logical and relevant, And most importantly its got to look really rad !
I want an idea not how to do it !
Any Ideas ???

What about an irregulat shaped dialog with picture background and then the AVI to indicate data movement
Happy programming!!
|
|
|
|
|
Hmm, I'm still trying to visualize your suggestion !

How about drawing a moving object using OpenGL?
|
|
|
|
|
How about embedding an mpeg player control in the dialog and showing two people doing "it".
Actually something more indicative of what the *user* will be doing, show an mpeg of a guy spanking his monkey...
|
|
|
|
|
"show an mpeg of a guy spanking his monkey..."
So you'd like to see a bloke 'tossing his caber' whilst the data is downloading. urrrrrhm.

I'm trying to integrate my C++ code to MFC, and am stuck 
can you tell me what all I have to do "to transfer a stream of data into or out of a rich edit control"
I tried MFC help and am confused.

If you just need "plain text", you can use (CRichEditCtrl: GetWindowText(...) and (CRichEditCtrl: SetWindowText(...).
If you need to ge/putt RTF from the control, look into the CRichEditCtrl::StreamIn(...) and CRichEditCtrl::StreamOut(...) functions or the "EM_STREAMIN" and "EM_STREAMOUT" messages.

class A multiply inherits from class B and C.
Class B has function B::fn(int arg1).
Also, class C has function C::fn(int arg1, int arg2).
Which is correct way to use fn from A ?
|
|
|
|
|
easy - the function called is decided by the arguments provided. I assume class C's function has no default values ? If it did, you'd need to define where like this
C::fn(int arg1)

P.S. Chris, why am I not logged in ? ARGH !!!

Normally, a function hides a function with the same name in a base class. However, in this example where B and C are at the same level in the inheritance tree, any call to A::fn() is ambiguous, even though they have different parameter lists, because there are two fn's in the definition of A. Neither fn() hides the other.
You need to call them thus:
class B {public: void fn(int arg1) {} };
class C {public: void fn(int arg1, int arg2) {} };
class A : public B, public C {};
A objectA;
objectA.B::fn(1);
objectA.C::fn(2,3);
Wacky syntax there.

which is better between the following two ?
(1) int i;
for(i=0; i<8; i++){ }
and
(2) for(int i=0; i<8; i++){ }
|
|
|
|
|
Well, to qoute an etseemed former colleauge, 'it depends'.
for(int i = 0; i < 19; i++) {
++i;
}
++i;
It's a question of scope basically, muddied by the fact that in the C++ standard the scope of i here should end with the '}' - but not all compilers support this yet. Stylistically, I like this form, and it follows the practise of declaring vars when you need them. Of course, form one allows you to reuse i in another loop on a conforming compiler.
|
|
|
|
|
what is diff between the following two c++ statements? Where to use which?
(1) for(int i=0; i<8; i++) and
(2) for(int i=0; i<8; ++i)
|
|
|
|
|
The second might be considered academically more efficient, since there's no need to create a copy of i.
In practise, however, compilers tend to be smart enough to generate the more efficient code in a context like this. I forget author of the CUJ article I read on this - one of the regular QA guys - Becker?.
Had me preferring the second version for a couple of days, but old habits die hard

We should blame the guy who gave the name C++ to this language but not ++C

In the case of the for loops, effectively nothing,
but in the case of :-
char array1[10], array2[10];
char c = 'a';
int i = 0;
int i2 = 0;
while(i < 10)
{
array1[i++] = c;
array2[++i2] = c;
c++;
}
The two arrays are not the same!
Indeed array2[0] is uninitialised, and array2[10] doesn't exist! (well you've overwritten the end of the array
So if you are going to use ++i careful how you use it in
your (especially compound) statements.

Does anyone has come across procedures in recording and playing back voices on a microphone using MS VC++ 6.0 API ?
|
|

I just posted this with you in mind,
But I'm unsure if its what you are looking for
Any how
Good luck

C:\msdn cd1\Samples\Msdn\Techart\asfasasfas\print.cpp(578) : error C2440: '=' : cannot convert from 'void *' to 'struct HINSTANCE__ *'
Conversion from 'void*' to pointer to non-'void' requires an explicit cast
C:\msdn cd1\Samples\Msdn\Techart\asfasasfas\print.cpp(590) : error C2440: 'initializing' : cannot convert from 'void *' to 'struct tagDEVNAMES *'

Can anyone tell me what error is this and how to rectify it?
Thanks a lot

This is sometimes a symptom of porting C code to C++, since C's parameter type-checking is less strict than C++.
I think you'll get some more info on this if you search this forum for 'cast' or 'explicit'. Always a fun topic!

My code is below and the error occurs at "hOldBitmap = SelectObject(hMemDC, hBitmap);" show below. I tried adding static_cast< ...> in front of the input hMemDC & hBitmap but got syntax error. So what should be done to the code?
HBITMAP CopyScreenToBitmap(LPRECT lpRect)
{
HDC hScrDC, hMemDC; // screen DC and memory DC
HBITMAP hBitmap, hOldBitmap; //
....
hScrDC = CreateDC("DISPLAY", NULL, NULL, NULL);
hBitmap = CreateCompatibleBitmap(hScrDC, nWidth, nHeight);
hMemDC = CreateCompatibleDC( hScrDC);
.....
hOldBitmap = SelectObject(hMemDC, hBitmap);
}
|
|
|
|
|
try:
hOldBitmap = (HBITMAP)SelectObject(hMemDC, hBitmap);
This is actually a 'C style' cast. You'll see this kind of casting done a lot in typical Windows code.
Also, one often resorts to it in dealing with MFC functions that return a CWnd, when what we really want is a CWnd derivative:
CButton *pButton = (CButton*)GetDlgItem(IDC_MY_DIALOGS_BELLY_BTN);

I thank you for your earlier suggestion which helped solve most of my errors but it could not solve one error.
extern HANDLE ghDLLInst; // Handle to the DLL's instance. Set in DllMain.
.....
...
int APIENTRY InstallHook (HWND hWnd, BOOL bCode )
{
....
...if (bCode == bHookInstalled)
return 0;
if (bCode)
{
hHook = (HHOOK)SetWindowsHookEx(WH_KEYBOARD, (HOOKPROC)KeyboardHook, (HANDLE)ghDLLInst
, 0);
......
}
....
}
The error lies in the line"hHook = (HHOOK)SetWindowsHookEx(WH_KEYBOARD, (HOOKPROC)KeyboardHook, (HANDLE)ghDLLInst
, 0);" the complier says that cannot convert parameter "ghDLLInst" from 'void *' to 'struct HINSTANCE__ *' Conversion from 'void*' to pointer to non-'void' requires an explicit cast.
So how to solve this ? Anyway thanks alot for your earlier help.
