Your requirement can be met by using Windows Media Player component for playing audio/video files. Follow the below steps:
Create a dialog box application.
Select Project->Add to Project->Components and Controls.
Select Registered ActiveX Controls folder
Select Windows Media Player component
When you select, a confirm classes dialog box appears. Click "OK"
Go to your dialog resource. Windows Media Player icon would be displayed on the controls selection view.
drag drop the control onto your dlg box. Add a member variable for the control in the class wizard.

Use 'SetURL' and GetControls() methods of the media player object for controlling the audio/video files (like play, pause, stop etc.)

E.g
m_MPlayer.SetUrl("D:\\Songs\\Xyz.mp3");
m_MPlayer.GetControls().play();

FYI: I am using Windows Media Player Ver 11

Hope this helps! Smile | :)

I created a test application and I am using GetControls() method, which returns an object of class CWMPControls. This class has all the control methods like play, pause, stop etc.
As I said earlier I am using WMP ver 11. I am not sure if the above class is defined for earlier versions of the WMP control.
Try to upgrade your WMP to 11 and check it out. If it doesn't work out.. I'll share my test source code then..

At what point are you looking at dt? If it's before the assignment, it will indeed be empty.

Right-click on the taskbar and choose properties.

Clear the "on top of other windows" box
Or maybe use auto-hide.

Hi all, would anyone happen to know the equivalent of comparing a string declared variable or character? Sort of like strstr or strcmp, i just cant find which one is used for C-like string. Thanx in advance!

strstr and strcmp does not work for string unless its declared as a char

I dont know what to search for because i've already tried Google and nothing came up that refers to what im looking for.

Stuff like this?

strcmp(str.c_str(), str2.c_str());
wcscmp(str.c_str(), str2.c_str());

operator== ( <string> )[^]

You may try the following

CString s1, s2;

if ( s1.GetLength() != s2.GetLengtth() )
// Not equal
else
{
for( int i = 0; i < s1.GetLength(); i++ )
{
if ( (Byte) s1.GetAt(i) != (BYTE) s2.GetAt(i) )
break;
}
if ( i != s1.GetLength() )
// String Not equal.
else
// String equal.
}

Hope this will help u, if ur string length is small.

Ram

Why do people continue to recommend using CString methods when the OP is using a string object? It just doesn't make sense. Roll eyes | :rolleyes:

Furthermore, why would you not just use CString's Compare(), CompareNoCase(), or == operator?

Try using CString::Compare.

// example for CString::Compare
CString s1( "abc" );
CString s2( "abd" );
ASSERT( s1.Compare( s2 ) == -1 ); // Compare with another CString.
ASSERT( s1.Compare( "abe" ) == -1 ); // Compare with LPTSTR string.

"string" class has overloaded "==" operator. You can directly use the == operator.

Eg:

string s1("hi");
string s2("hello");

if (s1==s2)
{
....
}
else
{
....
}

Hi All,
Does anybody out there know of any functionality that returns the maximum size of the recycle bin?, or is there any functionality to scale the size of the recycle bin?. Im aware of SHQueryRecycleBin, which will get me the current size information but what im after is finding out whether a file will fit into the recycle bin. In order to delete the file im using SHFileOperation but im not using and UI attached to it, nor do i want to as i would like to handle any messages by my own system.

Regards

BM_SETIMAGE doesn't work in XP

kenmckaba18-Jul-07 11:29

I want to have a button with an icon and text. I used Visual Studio to create a dialog based MFC app and added this to OnInitDialog and made the OK button bigger:

// TODO: Add extra initialization here
HICON voipIcon = (HICON)::LoadImage(AfxGetResourceHandle(),
MAKEINTRESOURCE( IDR_MAINFRAME ),
IMAGE_ICON, 48, 48, LR_DEFAULTCOLOR);

::SendMessage(::GetDlgItem(m_hWnd, IDOK), BM_SETIMAGE, IMAGE_ICON, (LPARAM)voipIcon);

The icon and text appear correctly on Vista, but on XP only the text appears. Also, it only appears under Vista if the manifest has a dependency on Common Controls v6.

If I set the BS_ICON style on the button the icon appears with no text. This is expected behavior based on the MS documentation: http://msdn2.microsoft.com/en-us/library/ms673567.aspx.

Any ideas why the icon and text only appears on Vista? Why does it require Common Controls v6?

Thanks,
Ken

Maybe if you derived CButton you can solve this problem.
