I am developing an application to play mp3 files using directshow .I want to show visualization like windows media player .But I am not getting how do i this . Is there any filter or any technique to show visualization in custom mp3 player.
|
|
|
|
|
what's the meaning of 'visualization'?
it's my pleasure to make friend with you.

Visualization is the visualization effects on to the renderer screen. such that when we play mp3 or any audio file in the media player then in the media player it produces the Album Art or Bars & Waves or Battery visualization effects.

I have a SDI project. I try to change the background colors of both its View and Frame.
For the View, i try :
CMyView::CmainframeView()
{
m_brush.CreateSolidBrush(RGB(100, 255, 100));
}
BOOL CMyView::OnEraseBkgnd(CDC* pDC)
{
return TRUE;
}
void CMyView::OnDraw(CDC* pDC)
{
pDC->SelectObject(&m_brush);
CRect rect;
pDC->GetClipBox(&rect);
pDC->PatBlt(rect.left, rect.top, rect.Width(), rect.Height(), PATCOPY);
}
and it works really well ! But when i try to change background color of CMyFrame :
int CMyFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
m_brush.CreateSolidBrush(RGB(255, 0, 100));
}
BOOL CMyFrame::OnEraseBkgnd(CDC* pDC)
{
return TRUE;
}
void CMyFrame::OnPaint()
{
CPaintDC pDC(this);
pDC.SelectObject(&m_brush);
CRect rect;
pDC.GetClipBox(&rect);
pDC.Rectangle(rect);
pDC.PatBlt(rect.left, rect.top, rect.Width(), rect.Height(), PATCOPY);
}
the background color only changes when the window is resize, but it flirt. I also try to hande WM_SIZE message but it doesn't help. Can you give me some suggestions ?

Not really sure what you're trying to achieve by painting on the frame because the frame is pretty much covered with other things.
CPaintDC will only give you the DC for the client area.
To paint other areas, use CWindowDC.

I have two DateTime picker Controls in my dialog: (1) One is for collecting the Users selected date(style is: :spin Control) the other control is (2) simply collects the time the User selects.
In (1) which selection do you select in the Property Page for the control, ie, DTN_DATETIMECHANGED, etc. And once you have made that selection what is the code (in MFC) for retrieving the data?
In (2) which selection do you select in the Property Page for the control, ie, DTN_DATETIMECHANGED, etc. And once you have made that selection what is the code (in MFC) for retrieving the data? I want to insure the format recieved is hh:mm (no seconds).I need sample code for each control: (1) and (2).
I need working examples; if you do not have such, don't bother responding, PLEASE!

Use the GetTime() method.

David, the first (1) picker has an assigned varable of m_cDate and the second (2) has an assigned varable of m_cTime. if I use CString str = m_cDate.GetTime() will it return a str with the value in the picker? and should this value be received in the DTN_DATETIMECHANGED notification function or what function should I select in the PropertyPage for the picker? I don't know, that's why I'm asking?

No, it "returns" a SYSTEMTIME pointer, a COleDateTime object, or a CTime object.

Simply put; how do I get the value the User has selected in the picker into a CString? simple code plese!

Did you look at any of the three objects I referenced?
Use one of those along with CString::Format().

If you are talking about this: "No, it "returns" a SYSTEMTIME pointer, a COleDateTime object, or a CTime object."
I still don't understand how what the User selects will be relayed to the instance of one of these " "returns" a SYSTEMTIME pointer, a COleDateTime object, or a CTime object."
when You initialize the m_cDatew or m_cTime varables with one of those; how will it also retrieve the User's response? Wouldn't you receive back the same initialization you inputed to the varables?

By using the GetTime() method. It comes in three different flavors depending on what type of object you want in return.

Hello everybody,
I've got a console project generating 6 elements combinations of strings(6 out of 10)for example:
ia11,ia72,ia190,ia21,ia102,ia180
ia11,ia72,ia167,ia64,ia102,ia178
etc...
(altogether 210 combinations)
I've also got a map:
typedef map<string,vector<int> >container;
container::iterator it;
container map;
map.insert(make_pair("ia11", via11));
map.insert(make_pair("ia34", via34));
map.insert(make_pair("ia72", via72));
map.insert(make_pair("ia167", via167));
map.insert(make_pair("ia190", via190));
map.insert(make_pair("ia21", via21));
map.insert(make_pair("ia64", via64));
map.insert(make_pair("ia102", via102));
map.insert(make_pair("ia178", via178));
map.insert(make_pair("ia180", via180));
The map has also string keys(the same as in the console output in order to make comparison possible).
That's because I want to populate the console output with integer values from the map vectors.
In other words the map is the source of data for the output. To put it in other way: when we've got ia21 in the output, the programme should compare it to the map and find a string key in the map (which is ia21 too) and after that insert values of integer from the vector(value in the map)into the string output.
What is the simpliest way to do it? What classes, compare functions or bool operators should I use?
I would be grateful for any kind of help!

Use map::find[^] to search for the string in the map.
It will return an iterator which will be equal to map::end[^] if the string is not found.
The iterator has a parameter called second which will be the vector of integers.
Use second to get an iterator to a vector of integers and iterate from vector::begin till vector::end to read all the integers.

Dear Superman,
I have thought out what you said last night and tried to take your advice practically, but somehow it doesn't work. (I also came to a conclusion how little I know about iterators. I promise to learn more about them.)The code map::find consists of two parts. And to be honest I'm not interested in finding one or two vectors in the map (this is in the first part of the code). My task is to find all the vectors matching the string output keys.(if I understood it correctly, this would be the second part about using a dereferenced iterator, but I'm not sure). The fact is I got completely lost in those damn iterators!
Here's what I wrote with header files to compile and run it.
cpp. first-
#include "IndexCombination.h"
using namespace stdcomb;
void CIdxComb::Init( unsigned int SetSize, unsigned int CombSize )
{
// Assign CombSize

m_LastIdx = CombSize - 1;
// Assign SetSize

if( CombSize > SetSize )
CombSize = SetSize;
m_SetSize = SetSize;
m_LastSetIdx = SetSize - 1;
}
bool CIdxComb::SetSizes( unsigned int SetSize, unsigned int CombSize )

if( SetSize == 0 )
return false;
if( CombSize == 0 )

if( CombSize > SetSize )
return false;
m_ArrSize = CombSize;
m_LastIdx = CombSize - 1;
m_SetSize = SetSize;
m_LastSetIdx = SetSize - 1;
return true;
}
bool CIdxComb::GetNextComb( std::vector<unsigned int> &vi )
{
// Check if the last element is at the end
if( vi[m_LastIdx] == m_LastSetIdx )
{
if( m_ArrSize == 1 ) // Completed
return false;
// Check if the subsequent elements(counted from back)
// is also at their subsequent positions
//////////////////////////////////////////////////////
bool Completed = true;
// Incomplete Index, init value not used
unsigned int IncompIdx = m_LastIdx - 1;
bool FirstIdx = false;
unsigned int ArrIdx = m_LastIdx - 1;
unsigned int SetIdx = m_LastSetIdx - 1;
while( !FirstIdx )
{
if( vi[ArrIdx] != SetIdx )
{
Completed = false;
IncompIdx = vi[ArrIdx] + 1;
break;
}
if( SetIdx )
--SetIdx;
if( !ArrIdx )
FirstIdx = true;
else
--ArrIdx;
}
if( Completed )
return false;
else
{
for( unsigned int i=ArrIdx; i<=m_LastIdx; ++i, ++IncompIdx )
{
vi[i] = IncompIdx;
}
}
}
else if ( vi[m_LastIdx] < m_LastSetIdx )
{
(vi[m_LastIdx])++;
}
else // bigger than the m_LastIdx! Impossible!
{
return false;
}
return true;
}

Hello.
How get the video card memory size(total physical video ram size) under vc++ ? 
I tried with IDirect3DDevice9::GetAvailableTextureMem(); ,but not work. 
Thanks for help!

Try to get this info using WMI and Win32_VideoController based on COM API for WMI.I'm not 100% sure but MaxMemorySupported member of this class should do the job. 
Life is a stage and we are all actors!

but doesn 't work.

I have a wizard application and it was all necessary to use such function in scenarios where I let the user to skip some pages..
Searched the internet, with no use, yesterday and consequently posted my question 10 hours ago but was all sure that if there would be a solution then an answer won't be sent until the sun reaches the US.
Thanks.
