Invoke Default Mail Client (with attachment) [modified]

hi

I want to invoke the default mail client with a specific file as attachment.
i tried mailto:xyz@xyz.com&Attach=".." but could not invoke the mail client with the attachment.

So I tried another approach by using a dll which uses MAPI and was able to invoke the default mail client with attachment but this doesn't work with MS Outlook. Frown | :(

is there any other way to accomplish this??

Any links or suggestions would do fine.....

Nope. At least not consistently. MAPI doesn't define the URL layout that an e-mail client should handle.

As you've seen, what works with one client won't work with another.

You might be able to look up the default e-mail client, or let a user choose if there are more than one, and then use the correct format for the client.

I've written MAPI code and tested it with Outlook, so I know it can be done. Post your code.

SOS urgent Help Required!!!Worker Thread Trouble

I need to implement a worker thread in an dialog based MFC. the thread callback function (controlling function that i want to use must be a member of the dialg class itlself but the only functions that the AfxBeginThread function is accepting is the function identifier of a global function of type
AfxBeginThread(MyFunc,....);
//the above statement is to be used in a member funciton(button click event) of a dialog based //MFC.exe

UINT MyFunc(LPVOID lpParam);
How can i use AfxBeginThread if MyFunc also needs to be part of the MFC dialog Class.
Any help in this matter would be great.
If any sample code can be given that would be wonderful.

First declare a funtion in your class

static UINT MyFunc(LPVOID pParam);

now onButtonClick()

<br />
OnButtonClick()<br />
{<br />
 CWinThread* pThread = AfxBeginThread( MyFunc, this,<br />
                        THREAD_PRIORITY_NORMAL,<br />
                      0, CREATE_SUSPEND, NULL);<br />
<br />
 if( pThread != NULL ){<br />
    pThread->ResumeTrhead();<br />
 }<br />
}<br />
<br />
UINT classname::MyFunc(LPVOID pParam)<br />
{<br />
  classname* obj;<br />
  obj = (classname*)pParam;<br />
...<br />
}<br />

When using worker threads keep this in mind. Don't directly manipulate any window / control that your thread did not create! If you must update a window / control, post a message by using PostMessage to the main thread.

Please read Joseph Newcomer's essay on worker threads here: Using Worker Threads[^].

In addition to the _anil_'s message, after you obtained a pointer to your dialog in static MyFunc function, you can simply call the dialog's member function you need, for instance:

<br />
UINT classname::MyFunc(LPVOID pParam)<br />
{<br />
  classname * const obj;<br />
  obj = (classname*)pParam;<br />
  obj->DoWork(); // call member function<br />
  return 0;<br />
}

It is probably preferable to declare this function as a static member function, inside your class. In this way, you are able to call DoWork even if it is private.

you can use GetPixel(x,y) in the loop like this
R=GetRValue(Image.GetPixel(10,10));
m.SetPixelRGB(10,10,R,120,120);
of course this way isnt good because you need to two loop for x and y and if your picture is 1024x768 its not good.
----------
Another way you can draw your bitmap on the dc and use from graphic functions (for example Graphics)
----------
you can codeproject examples that are helpful

Crazy with USB Audio device Mapping! Help pls

Dong Nguyen2-Jun-06 0:42

Hello,

Can anybody help me how to distinguish 2 USB audio devices? I have one PCI2USB card (4 ports) and have 4 USB composite (HID + Audio) devices, which can be use which Skype. Anytime I reboot my PC the device name changed, sometimes it is "USB Audio Device", sometimes it is "USB Audio Device 2", sometimes it is "USB Audio Device 3", and sometimes it is "USB Audio Device 4". Anybody know how Windows assign the USB device name? Any naming convention? And finally, how can I get the VendorID/ProductID from the device name? (For example, i want to know if "USB Audio Device 4" is mapped to which vendorID/ProductID?

Thank you in advanced

Best regards,
Dong

Hi I hope that you might have known the GUID of your device.
Then you can search for the GUID in registry
[HKYE_LOCAL_MACHINE\SYSTEM\currentcontrolset\control\class]
under this key you will find your GUID key
under your GUID key thir will be one
"MatchingDeviceId" key which stores VID and PID.

Anil

Anil,

Thanks for quick reply.

Seem that under HKYE_LOCAL_MACHINE\SYSTEM\currentcontrolset\control\class, all USB audio devices have the same name "USB Audio Device". I could not find "USB Audio Device (2)", "USB Audio Device (3)", and so on. But if I open Sound and Audio Devices Properties Dialog, I could see 4 USB Audio Devices "USB Audio Device", "USB Audio Device (2)", "USB Audio Device (3)", "USB Audio Device (4)". I could recognize my USB device is "USB Audio Device (2)". But next reboot, my device may be named as "USB Audio Device (3). So, my previous setting becomes wrong.

Best regards,
Dong
