One solution is NetServerEnum(). Check out MSDN.

hello again,
i refered your suggession and created one MFC application ....in which i m creating a button , a combo box a list box and some other control for my project.
1. what i did (achieved) is :
when i clicked the button the application is flooding the no of domains ,servers and the individual computers at a time in a sequence by a callback function NetServerEnum() (callback --->i think so till now not checked) & i m displaying in the list box. but my requirement is different in the following manner ....
2. my requirement is :
when i click the button the application should enumerate the no of domains first and should put in the combo box.then when i will select one of the domain from the combo , i should get the list of computers in that particular domain , which i want to show in the list box.
how to do that ... using the same function ...??
please guide me ...
thanking u.

Hi,
I need to access the XML data stored in a IWebBrowser2 (a CHtmlView in fact) to update some nodes without reloading the page, but I can't find how to do this.
I can update the final HTML result, but not the original XML data (I use XSLT to display the data)
Do someone have an idea ?
Thx

Off the top of my head and I say this isn't possible. I'm using the Webbrowser control in a new app (see www.surfulater.com[^]) and have written a lot of code to interact with it, but I haven't tried embedding standard Windows controls. You can probably only do this with an ActiveX control.

Hi,
I am trying to print to a network printer from a isapi exstension service on a web server. Basically I want to have the web server print a label automatically in response to certain http posts from a client. Ive got everything going except for the most important part. The printing. I cant seem to find any info on printing without using some sort of form. I would like to just print two, centered lines to a label printer. Any Ideas on this? Much Thanks in advance.

Your ISAPI dll is just another dll except that it is called by a web server instead of an application. You can call the traditional device context functions to print, such as CreateDC("WINSPOOL", "HP LaserJet 5P", NULL, NULL) and StartDoc, StartPage, gdi drawing functions, EndPage, EndDoc, DeleteDC, or you can opt to write directly to the print spooler with functions such as OpenPrinter, StartDocPrinter, StartPagePrinter, WritePrinter, EndPagePrinter, EndDocPrinter, and ClosePrinter.
The only real restrictions are that you should not create any windows, nor should you assume that you can access network resources, since your dll may be running under the localsystem account.
If you choose the DC method, you can use the WINAPI functions with HDC handles, or choose to use the MFC CDC class.
onwards and upwards...

I have created a ActiveX control using ATL.
The ATL control houses an MFC based control (that is use in other app). The ActiveX library also makes uses of some code that uses sockets and is multithreaded. The DLL itself is a CWinApp based class.
The problem is that when the DLL registers itself, all the initialization calls work fine, but when the closing ExitInstance call is made, it hangs while I try and clean up a thread, first telling the thread to stop, and then calling
WaitForSingleObject( threadHandle, INFINITE );
to wait till it's gone. This works fine when the code is used in an EXE, but used as part of the ActiveX DLL it just hangs.
Is there some trick I am missing to making an ATL based ActiveX control work with multiple worker threads?

How are you telling the tread to stop? If you control is Apartment threaded and you make an incoming call to the thread that created an (COM) object after you have told the thread to stop, you must pump messages as you wait for a worker thread to stop.
Try replacing the WaitForSingleObject with MsgWaitForMultipleObjects - including a message pump. Do a search for MsgWaitForMultipleObjects on MSDN, there is an example in there somewhere.
If that doesn't work try posting the code for the worker thread (the main 'loop' of it) along with what you do to make it stop.

Hey everyone,
I was wondering what would be the best way for me to prevent memory leaks in my application. I was also wondering if anyone could tell me how to test or check for memory leaks possibly caused by my application? Thanks in advance for your help!!

I will diffently try this out......Thanks John!

Good coding practice will remove all but a few "documented" leaks in the OS/frameworks.
if on Windows and using MFC, you can and should use the DEBUG_NEW macros to help you trace some of the memory leaks.
#ifdef _DEBUG<br />
#define new DEBUG_NEW<br />
#undef THIS_FILE<br />
static char THIS_FILE[] = __FILE__;<br />
#endif

Follow some simple rules:
1. Use smart pointers rather than "raw" ones. I reccomend ones from the Boost library. Watch for circular references when you use reference counted ones.
2. If you must use raw pointers, before every new put a comment like: "Who is responsible for deleting this?" and make sure that a matching delete is called in all scenarios.
3. If appropriate, look for some garbage collector library. At least one of them can be found on Code Project, and the most popular one is Boehm's[^].

Or do what I do - as soon as you write a new statement, immediately write the corresponding delete statement. Same with any other memory allocation.

Hi All,
Iam not able to delete a directory, which has more than three dot(.)s in its name using SHFileOperation. But iam able to delete directory will two dot(.)s. Why this happens?
Eg. Iam able to delete directory named "1212.1212". But, Iam not able to delete directory named "192.168.1.133".
I get message as
"Cannot delete file: cannot read from source file or disk".
but the directory is present.
How can i delete this directory??
Is this due to Dos Name problem??
With Best Regards,
A.Ilamparithi

At a guess, it looks like the directory name is being interpreted as an IP address. You may need to prepend additional information ro fully qualify the actual location of the directory.
e.g.
"C:\192.168.1.133"

Hi
I tried with full pathname only like the one you mentioned above.
eg.
SHFILEOPSTRUCT shFileOp;
ZeroMemory(&shFileOp, sizeof(SHFILEOPSTRUCT));
_TCHAR *p="c:\\temp\\temp1\\192.168.1.133";
shFileOp.hwnd=NULL;
shFileOp.wFunc=FO_DELETE;
shFileOp.pFrom=p;
//shFileOp.fFlags=FOF_SILENT/*|FOF_NOCONFIRMATION*/;
SHFileOperation(&shFileOp);
Regards,
A.Ilamparithi

Isn't the filename supposed to be double null termainated. That may cause a problem...
Address of a buffer to specify one or more source file names. These names can be either fully qualified paths, or standard DOS wild cards such as "*.*". Although this member is declared as a null-terminated string, it is used as a buffer to hold multiple file names. Each file name must be terminated by a single NULL character. An additional NULL character must be appended to the end of the final name to indicate the end of pFrom.

Hi everyone,
I have a DLL with some classes in it. Header file have dllexport feature on class.
This class has some methods, several of them are virtual.
So, the problem is that my test app looking for Foo method in DLL, but can't find it because in DLL it's defined as FooA, but not Foo.
Can somebody tell me what's wrong?
In this [post^] I describe situation in detailes with some code examples.
Thanks in advance,
va'Lery.

I'm not positive on this, but I believe the A specifies that the function is cdecl. I'd double-check the calling conventions.

Thanks for an idea.
I tried all three possible conventions, but result is still the same.
So that's not it.

I suspect that in the DLL, the function has the same name as a Windows function whose header you have included, while you haven't included the same header in the application.
Example: the Windows header WinBase.h defines the functions DeleteFileA and DeleteFileW. It also maps the name DeleteFile via a macro to DeleteFileA or DeleteFileW depending on whether the UNICODE symbol is defined. This allows you to switch between using the ANSI and Unicode versions of the functions simply by defining or undefining UNICODE.
Unfortunately the macro processor has no idea of scope and doesn't realise that you actually wanted to refer to a class member function rather than to refer to the Windows function, so it replaces your Foo with FooA.
Solutions: either rename the function, or #undef the macro. If you #undef the macro, consider using #pragma push_macro and #pragma pop_macro to store and retrieve the macro value (supported in VC 6.0, even though undocumented).
Using #undef in this way is a real hassle, though, so I'd simply rename the offending function.

That's it!
You're absolutely right. 
Thanks a lot!
