Hi
I want to Activate project setting dialog by choosing menu item "Project"->"Settings...". but I cant find where settings in project menu.
The image shows my project not having any "settings"

Thank you.

Have you tried test opencv properties[^]?

That does not seem a setting for project because I need to Choose "C/C++" tab -> "Preprocessor" category. In test opencv propery does not have C/C++ tab

C/C++ tab would be just right there under configuration properties.

I won't click on another link if it ponits to a 2 Mb Bitmap. Why can't you upload it as a JPG?

And to solve your problem, is that an empty project[^]? The C/C++ settings applies for the files that belong to the properties of a project. So, if you don't have files, then the tab shouldn't appear. Try adding files to your project first.

There are no settings for C++ because you don't have any files in the project. Add some files and the settings will appear.

Hi All

I am useing SHFileOperation.Code is here

void CAbc::OnBnClickedButton1()
{

	CString pzFrom=_T("C:\\Test\\");
	CString  psTo=_T("C:\\");
	CopyFolder(pzFrom, psTo);

	
}
void CAbc::CopyFolder(LPCTSTR pszFrom, LPCTSTR pszTo)
{
	
   SHFILEOPSTRUCT fos ={0};
   fos.wFunc = FO_COPY;
   fos.pTo   = pszTo;
   fos.pFrom = pszFrom; 
   
   ::SHFileOperation(&fos); 

   
  
}

Both Directory exits.I am geting Error this on Dailog Box

Could not find this item

  This is no longer in C:\Test\.Verify the Item's location and try again.

I am not to figure out why this is happen.Becouse both directory exits.

Hi,

There you have just specified two folders name.
What happened to the file name.
Because its SHFileOperation file operation..

Of course when you use of this phrase you must be wait for CPallini but
your code is working for me:

SHFILEOPSTRUCT p={0};
p.wFunc = FO_COPY;
p.pTo   = _T("c:\\");
p.pFrom = _T("c:\\2\\1");

SHFileOperation(&p);

You got this error because you use of p.pFrom = _T("c:\\2\\"); but you must be set a name after \\

Did you try to use flags for SHFILEOPSTRUCT, like FOF_MULTIDESTFILES ? Did you read the documentation?

Try this:

LPCTSTR lpFrom = _T("D:\\SymbianDev\\Test\0");
LPCTSTR lpTo = _T("D:\\SymbianDev\\Test1\0");

SHFILEOPSTRUCT fos ={0};
fos.wFunc = FO_COPY;
fos.pTo   = lpTo;
fos.pFrom = lpFrom;

if(::SHFileOperation(&fos) == 0)
    cout<<"SHFileOperation succeeded"<<endl;

One suggestion

Rajesh R Subramanian wrote:
LPCTSTR lpFrom = _T("D:\\SymbianDev\\Test");
LPCTSTR lpTo = _T("D:\\SymbianDev\\Test1");

should end with two null characters
At least document says that i don't know if it works without that Smile | :)

Luckily, it works. But that's a good point there. I will modify my previous post.

Thread synchronization

Hi all,

I am having a list(queue)of tasks. My two threads are using the same list.

First thread is to insert the task into it. (appending the list)
Second thread is to process on each task . ( reading the list)

My aim is to give the maximum availability to Thread one without hanging thread two.

How to synchronize both thread so that, second thread should not wait for long and First thread keep inserting the item into list.

Thanks in advance

critical section! look for CCriticalSection class in MFC!

A piece of good advice is to stay clear of the MFC synchronization objects because they are not working properly. They may fail under certain circumstances.
E.g. you cannot recursively lock a CCriticalSection from the same thread because it will cause a deadlock.
Use the Win32 API with ::EnterCriticalSection() and ::LeaveCriticalSection() instead.

Wow, thanks for the info Roger. I've never used the MFC sync objects before but I don't think I will ever use them now.

Yup, pretty amazing, isn't it?

But the evidence is right there in the code. Dead | X|

I've never used the MFC sync classes since I read Joe's advice many years ago in a much earlier essay of his.

Even though CCriticalSection may work if it's only locked once in a call chain, you will eventually find yourself in a situation where you should perform a second lock due to encapsulation and at that time you're smoked; a re-write using the Win32 primitives is essential before it has a chance of working.

If I build a Win32 Application in vs 2005 or 2008 it has no dependencies correct?

Hey Guys,

I have always used MFC, but now that I have upgraded to visual studio 2005 and 2008 I am forced to use MSI installers due to the depencies on the new merge modules. I really don't like the msi installer I think it's horrible and I would rather use inno setup or the old wise installer.

I just want to be sure.... If I was to start writing all my code in a pure Win32 Application from vs 2005 or 2008 I would no longer require the vcredist files in order to run my applications correct?

Thanks,
Greg
