How about:

string str;
CString cstr("Hello");
str = (LPCTSTR) cstr;

or:

basic_string<TCHAR> str;
CString cstr("Hello");
str = (LPCTSTR) cstr;

The encryption library should not affect the underlying algorithm. In other words, you should be able to encrypt the data using one library and then decrypt it using a different library.

If I call AfxEndThread within a thread will the dynamic memory that I have allocated in this thread be released or just the memory that MFC itself have allocated for it's inner needs. Thanks.

Until you call delete or the application is shut down, the memory remains allocated.

Hello everyone.

I am quite new at COM and DirectX programming, and I have some problems to understand how to use properly all of this stuff to build my own transform filter.

My app take the voice as an input, convert it into UMTS format and send it through the internet, at the end of it, the data stream is uncompressed and played. But this is just my dream. For now I would like to know how to build a Transform filter, and how to use the CTransformFilter interface.

I have started to build a COM object with VC++ ATL Wizard, but any "public CTransformFilter" throws me away, even if the appropriate "#include "Streams.h" and "Strmbased.lib" in the Settings.

Thanks for any kind of help.

When I using SetIpNetEntry( ), I got wrong IP in ARP Table

When I using SetIpNetEntry( ), I got wrong IP in ARP Table

MIB_IPNETROW at1;
...
at1.dwAddr = inet_addr("80.0.0.30");
//or at1.dwAddr = pMib->table[0].dwAddr;

SetIpNetEntry((MIB_IPNETROW *)&at1);

Then I get 0.0.0.30 in ARP Table instead of 80.0.0.30.
Even if I get MIB_IPNETROW by means of GetIpNetTable( ) and then insert it to SetIpNetEntry( ) I get 0.0.0.X
Help me.

CTabControl m_tabctrl;
img.Create(IDB_BITMAP2, 11, 4, RGB(0, 255, 0));
m_tabctrl.SetImageList(&m_imagelistTab);

pfirst=new first;-------->This is a Pointer from a dialog..
pfirst->Create(first::IDD, &m_tabctrl);
m_tabctrl.AddTab(pfirst,"", 0);

The Image is adding to the Label.But there is a small space remaining in the Label.I don't want to add Text to the Label.
So How do I add Image completely to the Tablabel with out remainng Space?

How to launch a .job file in VC++ ?

I want to launch a .job file in C:\Windows\Task\ directory.

I use system(), WinExec(), ShellExecute(), CreateProcess,

but they all don't work Frown | :(

Is there any other way to implement this function?

Thanks a lot Smile | :)

What is a .job file?

If it has a registered executable associated with the file extension then the process will start if you use ShellExecute() correctly.

A .job file is created by task scheduler.

We can launch the .job file by double clicking it,

but it can't be launched by using ShellExecute() in VC++.

Maybe it doesn't have the registered executable associated with .job file

extension.

CListCtrl flicker...

Hi All
i have a nice and groovy CListCtrl which is showing images (100x100)

I have a thread which inserts the images into the control as the images are received. (the number of images is unknown beforehand)

When an image arrived, i add it to the Imagelist and then i do a SetImageList
(and then finally give it a title with InsertItem)

When i have a largish number of images, the control fickers when an image arrives and is inserted ...
I was wondering if there was a better method for what I am trying to do and what would be the best way to rid myself of the flicker?
cheers

ovveride the folowing

OnEraseBkgnd
OnPaint

in the errasbackground method you should do nothing..
and in the on Paint you should do something like this:

void CIcoListCtrl::OnPaint()
{
	CPaintDC dc(this);
	CRect r;
	GetClientRect(&r);

	CMemDC memDC(&dc,&r);

	
	Errase(&memDC);
	CWnd::DefWindowProc(WM_PAINT,(WPARAM)memDC.m_hDC,0);
	
}

I have a CustomDrawListControl with Icons and the Icons are zooming on mouseenter and mouseleave...
and it dont flicker at all!

I hope this helps..

OK, If I have read correctly I should be able to take a single executable file from the development environment and use it on another Windows based machine if I statically link with the MFC dlls. I appreciate that this will make it a more cumbersome .exe but it keeps my customer happy. As a final check I will not need any additional dlls to permit database access since I accomplich that using the MFC CRecordset classes. Is this correct?

I currently use the standard edition of VC++ ver6 and think that I have to get the Professional edition to do this. Again before I spend the dollars am I correct?
