Please debug and check the reason for failure
but i have the alternate solution as to suggest you to use SDK APIs

CopyFile :: Copies an existing file to a new file.
CopyFileEx :: Copies an existing file to a new file.
CreateDirectory :: Creates a new directory.
CreateDirectoryEx :: Creates a new directory with the attributes of a specified template directory.
CreateFile :: Creates or opens a file object.
DeleteFile :: Deletes an existing file.

This may not be an answer to your question, but the easiest way to do this is to place a picture control with a bitmap of the text with the required font size over the group box.

You mean some text inside the groupbox or the caption of the groupbox? If the caption of the group box, you could rename the ID of the group box such that it is NOT IDC_STATIC and then add a control variable to it (say m_GroupBox) and then call m_GroupBox.SetFont();

It is a crappy thing, but it's life -^ Carlo Pallini

OK, try this code:

CFont f1;
LOGFONT lf1;
::ZeroMemory(&lf1, sizeof(lf1));
lf1.lfHeight = 16;
lf1.lfCharSet = ANSI_CHARSET;
lf1.lfWeight = FW_BOLD;
::lstrcpy(lf1.lfFaceName, "Arial");
f1.CreateFontIndirect(&lf1);
GetDlgItem(IDC_GROUPBOX)->SetFont(&f1);
f1.Detach();

Obviously you'll have to change some things to make it work with your code but you'll get the idea.

Edit:
Actually, you might want to clarify first what Rajesh asked:
You mean some text inside the groupbox or the caption of the groupbox?

Problem about WUA Api

Hi all,

In my program, I have the following statement:

ISearchResultPtr spIsr = spWuSearcher->Search(criteria);

Most of time, the program will excute successfully, but when "criteria" is _T("UpdateID='12345678-9abc-def0-1234-56789abcdef0'"), then spIsr->Updates->Count is 0, but not 1 which is the right value.

Is there anyone who knows why or when this happens?

NOTE: I'm sure the "UpdateID" is right.

Any reply is appreciated.
Thanks a lot Smile | :)

If my pointer is pointing an invalid object. How to find proactively in run-time.

there are some memory check functions as _CrtIsValidPointer()

It is strongly recommanded to avoid this situation. use pointers to data, only for copying the data, if you need it later. -> make your own object Blush | :O

To check the validity of the pointer in Windows there are API functions called IsBadReadPtr and IsBadWritePtr to do that.

P.S. While using pointer developer should be careful that pointer is set to NULL once it is deleted. And not to use the deleted pointer before allocating memory.

There is no reasonable and fool proof way to make this check.
You as a programmer must ensure that this never happens.

it is an endless loop, the condition is always true.
In

i=printf("Hello");

it will always be 5.

Re: output of for loop with condition as i=printf("hello")

Adam Roderick J23-Jul-09 22:37

23-Jul-09 22:37

syntax of printf is
int printf ( const char * format, ... );
so it returns the size of the characters displayed, here "Hello" number of characters is 5.
since

for ( i = 0; i = 5; i++ ) is condition on execution.

now u can see that i=5 is condition which will never ends, so its a infinite loop Smile | :)

Client Server Application

Hi,
I want to create a simple client server application by using CAsyncSocket class of MFC to send and receive messages(data) through internet connection. I found a lot of stuff for this at .net plateform but I want to do it in VC++ ( with out .net support).

I found article at this site helpful but could not make the application working.
http://www.codersource.net/mfc_window_socket_programming_server.html[^]

I could not figure out the sequence of operations properly even after having some time with msdn as well. I remember in old days there was a book named "VC++ in 21 days" and it has a chapter related with client server application.

Any link where I can find an MFC based code for the stuff or any tutorial for this work.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
