I would be very grateful to anyone who could give me some easy code to tell me how timers can be used in a MFC application in VC++6.0...
MSDN is not that helpful in the matter as i am getting only .NET hits...
I need to be able to call a purticular member function of the dialog class on timer event..

Define a timer id
#define ID_MYTIMER 201

Use SetTimer to set and initiate the timer .
SetTimer(ID_MYTIMER,1000,NULL);//1000 is the mseconds

Put your code in the OnTimer function . You can find it using the Class Wizard.
Use KillTimer() to stop the timer
Somethings seem HARD to do, until we know how to do them.

   There is one important thing to remember when dealing with Windows timers that people often forget. The SetTimer function returns the ID of the created timer. There is no guarantee that the actual returned ID of the created timer will be the same ID as requested.

   The return value of SetTimer(...) should be used to identify the timer in the timer-handling function and when destroying the timer.

   (Note that the link provided below to http://www.codersource.net/mfc_working_with_timers.html does this correctly, although it does something really stupid in the OnTimer(...) by using dynamically allocated memory for no good reason...)

   Peace!

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

Sharath862-Jun-06 1:05

Sharath86

2-Jun-06 1:05

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.

Re: BitMap coloring

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
