I don't know the answer ( well if there is a really easy way ) but you can try mouse hooks.

Well... I am a beginner ...

In the registry, set the HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System\NoDispCPL value to 1.

CreateNamedPipe permission question

Anonymous14-Jul-04 4:08

I have two apps which communicate with each other via pipes. When I logged in as admin, I was able to run it fine, but as a standard user, I could not run it. The CreateFile call to the named pipe would generate an ACCESS_DENIED error. I changed the security attributes on the CreateNamedPipe that I used on the server side. I did SetSecurityDescriptorDacl. This fixed my app's pipe connect problem. However, it created a new one. The messages on the pipe look like garbage. The messages looked fine before the security fix. Any ideas? Do I need to set the security attributes of CreateFile too???

how to validate access rights of a user on a folder??

Hi there!!!
On my system, there is a folder which can be accessed by a specific user(e.g. auser) of my computer. Administrator group has full access rights on that folder too. The problem is I need to validate the access rights of "auser" on that folder through programming. but dont know the specific API to do that. following API can do it, but still not sure:

GetNamedSecurityInfo(...)
GetTokenInformation(...)

Using GetNamedSecurityInfo(...) API, I can get the DACL of that folder. But how can I determine which user has waht access rights on that folder????

Would appreciate any advice as how to go abt it or any code snippet.
Thanks in advance.

try using _access(...)

if (_access("\\\\myserver\\myfolder\\", 6) == 0)
{
   // Read write permission for this folder
}

0 Existence only
2 Write permission
4 Read permission
6 Read and write permission

Thanks for replying. but unfortunately it only validates a specific rights on a file or a directory, contrary to what I am looking for Frown | :(

If I can translate my problem in an statement, it would something like this:
"Check 'auser' has read rights on directory(myfolder)????"
where 'auser' is a local user on a computer.

CString performance

i use CString to much i think, i've seen many people uses LPCSTR

am i losing much by using CString?

I don't think there's a huge performance loss when using CString; internally, it must be similar to using LPCSTR ( char* )é

For day to day operation, just the simpler usage of CString ( or std::string ) makes it up for the programmer at least.

it depends on how you use it! Smile | :)

CString is realy OK, the only thing
you should do is, if you pass a CString
as a parameter, pass it as const CString&
and dont an a lot of small datachungs
to a CString in a loop

int n=0;
CString dummy;
while(n<10000) {
 dummy+=(char)((n%30)+30);
 ++n;
}

AfxSetAppName( )?

I have an SDI application. The title bar text is:

FileName - AppName

My question is: how can I change AppName on the fly? I have a menu item to swtich between two options. I want the application title bar to reflect which option is currently selected. So I want the title bar text to be something as:

FileName - AppName option1
or
FileName - AppName option2

I searched MSDN, and found there is a function AfxGetAppName( ), but it is to get CWinApp.m_pszAppName. Is there a function to set the m_pszAppName?

Thank you very much for any hint.

So there are two major activities in your project.

1) Workiing with Serial Ports
2) Working with Modems

Which one do you want or need help with?
You might get more response to smaller more specific questions.

You must provide more specific information than that in order for someone to determine how to help.

Ok, In my project now, i'm working with serial port.

i've serial chat programming, and i try to send at command to modem.

I've tried with VCTERM from msdn, but i don't understand on it.Beside that i don't understand making a program with activex. So, i try with serial programming like chat program with serial because it can send character.

CFileDialog - customize

Hi, I want to pre-configure the state of the a CFileDialog (dialog) I use. What I want is the view to be set to "view Large Icons" or thumbnails.

Also, in another question, can I use the "Search (results) dialog" like a CFileDialog. My use would be a file/folder browse dialog that shows all possible files that match a certain file extension (.BMP,.JPG,.ICO) all under a common root folder.

Thanks!
Regards,
Johnny

Defaulting to large icons is easy enough using both CFileDialog and GetOpenFileName(). However, I've not been able to default to thumbnails using CFileDialog, only GetOpenFileName().

Either the parent frame is the desktop or the parent frame is a direct descendent of the desktop. Put a breakpoint on that line to see which of the two conditions is evaluating to FALSE.

Hi Raghunandan,

Did you subclass a view? It sounds like you are using a view where you should have a window. For example, CListCtrl is derived from CWnd but CListView is derived from CView.

Hi,
Mine is an SDI application where I do like this:
CSingleDocTemplate* pDocTemplate;
pDocTemplate = new CSingleDocTemplate(
IDR_MAINFRAME,
RUNTIME_CLASS(CConvertDoc),
RUNTIME_CLASS(CMainFrame),
RUNTIME_CLASS(CConvertView));
AddDocTemplate(pDocTemplate);

in my initinstance

CMainFrame is derived from CFrameWnd and CConvertView is derived from CEditView.

Is there any problme in this kind of creation?
