open your project properties

in the C/C++ section, there might be a "Additional Include Directories" section. then add the folder which contains the headers you need. be sure to add it on both debug and release configurations Wink | ;)

if u include a file say #include"Iostream.h" in any of ur project files, it will automatically get added in the external dependencies fileview.

Hi All,
I was trying with Michael Dunn's article on Introduction to COM

I had a try with my own console application. But in the beginning itself, it said that IActiveDesktop is undeclared. I included shlobj.h but no use at all.
But the sample he provided working fine Frown | :(

in VC++ 7.0 but mine is not working well Frown | :(

could you please help me in this regard?

Look in the header files. I've had a look and it seems that:
- WIN32_IE needs to be defined >= 0x400.
- _WININET_ needs to be defined.

You get _WININET_ defined by #includeing <WinInet.h> before you #include <ShlObj.h>. You typically define WIN32_IE in your "stdafx.h" with code something like the following:

#define _WIN32_IE	0x0400

Do this before you include any files.

Can I pass a parameter to the function if I have a worker thread and use AfxBeginThread?

From MSDN[^]:

CWinThread* AfxBeginThread(
   AFX_THREADPROC pfnThreadProc,
   LPVOID pParam,
   int nPriority = THREAD_PRIORITY_NORMAL,
   UINT nStackSize = 0,
   DWORD dwCreateFlags = 0,
   LPSECURITY_ATTRIBUTES lpSecurityAttrs = NULL 
);

pParam<br />
Parameter to be passed to the controlling function as shown in the parameter to the function declaration in pfnThreadProc.

Then ask a clear question. What is your problem ?? We cannot guess it.
Why don't you just pass your data (as a pointer for example) using this parameter ?

This is my controling function

UINT CMina_sView::run(LPVOID p)<br />
{<br />
		<br />
     CMina_sView * me = (CMina_sView *)p;<br />
     me->ascultarea();<br />
     return 0;<br />
<br />
}

And this is how I start the thread

void CMina_sView::OnList() <br />
{	<br />
     running = TRUE;<br />
	 AfxBeginThread(run, this);<br />
}

I want to pass a paramater to ascultarea. How do i do it?

You already passed a parameter to your thread: it's the address of the class (the this parameter). So, you cannot pass two parameters.

But, why do you want to pass a parameter to this function ? Why don't you just have a member variable that hold this variable so that the function ascultarea can use it ?

The OnList is a menu item that opens a dialog in which I can select smth a i hold that in dlg.m_sel. I want to be able to pass dlg.m_sel to ascultarea.

Please make a little effort on the spelling because I cannot understand (english is not my mother tongue).

When are you opening the dialog ? Before or after spawning the thread ? If it is after, then why don't you simply take this value (dlg.m_sel) and store it into a member variable of CMina_sView ? Then in your thread, as you call the function ascultarea, as it is inside the SAME class, you don't need to pass it to the function. The function can simply get it from the member variable.

I think the problem is that you don't know what you are doing. You probably found some snippet of code to start the thread but you don't understand the mechanics beyond that. Am I right ? Then, I cannot explain you in details because the subject is fairly too large. (And I already provided you with the solution).

1)I knew I should've studied french a little more in highschool.
2)I started programing in VC++ just one month ago but I've read and understood anything I could in one month.
3) I open the dialog and then I spawn the thread.

I already explained you the solution 2 times. Once more won't help you to understand it better. After one month of studying C++, it is not a good idea to jump directly to thread manipulation (even more if you didn't know a programming language before).

The only advice I can give you is: start slowly. Try to find a good book or course and start to learn the basics first. Otherwise, you'll screw up everything and you'll be really disgusted for life.

files displayed on the CFileDialog

see me27-Jul-06 23:14

see me

27-Jul-06 23:14

Hi,

I hav a class which derived from the CFileDialog.
I gave OFN_ALLOWMULTISELECT option for that.

I want to update the CfileDialog when I change the file extension. So I override the function OnTypeChange() in that ...

I don't know what is the next..?

How can I update the files displayed on the CFileDialog window, when i change the extension( file type ) ????

I just tried it...!
CFileDialog is not updating that...!

CString szFilter = "AVI Files (*.AVI)|*.AVI|Bitmap Files (*.bmp)|*.bmp|All Files (*.*)|*.*||";<br />
CFileDialog FileSelect( TRUE, NULL, NULL, OFN_ALLOWMULTISELECT, szFilter, this );

Dream bigger... Do bigger...Expect smaller

mem allocation in console app

if there is allocation of some memory in console application and then it quits without deallocation (that is mem leak). Will windows free this leak itself after console application is terminated?
