Unfortunately, no. The store app platform is very limited for security reasons.
Perhaps you could explain what you're trying to achieve and someone could suggest a workaround.
The difficult we do right away...
...the impossible takes slightly longer.

Is there any kernel equivalent of this method?
I can see IoVolumeDeviceToDosName(), not sure. if this is correct one.

Dear Friends,
I have requirement to disable UAC prompt through programmatically. Please anyone help me on this.
Thanks,

No. The UAC prompt is there to protect the owner of the PC.
|
|
|
|
|
That is not possible for the current login session because it would defeat the purpose of UAC.
You can change the setting using the registry but that requires a reboot to become active (see Enable or Disable UAC From the Windows Command Line[^]; it is for the command line but shows the registry settings to be changed).

whether its possible to assign administrator right to my application though programmatically. So that I can set value 0 or 1 to EnableLUA in registry.
|
|
|
|
|
Assigning administrator rights to an application requires administrative privileges. So while it does not have these, you can't change it. And you can not elevate the privileges of a running process.
You can use a manifest to specify that your application should run elevated, use the "runas" command or start other applications elevated from within your program. But in all these cases there will be a UAC prompt.
UAC is there for a reason. It is a security feature. The user decides which level of security should be used. An application can not bypass these settings.

l want to ask how l can do the following things in a tab control.
1)That is, for instance: In tab1, when a button is clicked, previous text is wiped and another is written. l had tried but all the texts overlaps and none cleanses off for new texts.
2)How can l erase the content of a tab control when l switch tabs. As in, when tab2 is clicked, contents in tab1 clears off and the things in tab2 only shows.
Thanks.

1. That means you are doing something wrong. Clearing the text of a windows control is quite straightforward.
2. Do you mean that you want to delete the entire tab, or just erase any text?
|
|
|
|
|
Yes, how l can erase the content(text) in a tab control.
Like, when next button is clicked, text content on the display area of the tab clears and another text is displayed.
Or moreso, when Next button is clicked, another question shows and so on.
Thanks.

It is impossible to say, since you have not given us any information about what tab control methods you are using, what controls you have on the tab, etc.

Then you must be doing something wrong. But, as I said earlier, without more detailed information it is impossible to guess what.
|
|
|
|
|
When you get the TCN_SELCHANGE notification (in a WM_NOTIFY message) you have to clear or hide the contents of the old tab and show the contents of the new tab yourself - the API doesn't help you with it.
|
|
|
|
|
Do you have any idea on how l can show the contents of the new tab as am only using TextOut function and not child windows/controls?
|
|
|
|
|
|
l have gotten a solution. l added the following lines of codes base on msdn WM_SETREDRAW message (Windows)[^]
SendMessage(hWnd,WM_SETREDRAW,(WPARAM)TRUE,0);
RedrawWindow(hWnd,NULL,NULL,RDW_ERASE | RDW_FRAME | RDW_INVALIDATE |RDW_UPDATENOW |RDW_NOCHILDREN );
Thank you all who contributed.

Hi,
I have a CAsyncSocket which is a member of a CWinThread class. The notifications however m OnSend, OnReceive seem to go the Main Thread.
Do I need a Window or does the thread CWinThread ( a UI thread ) have to have the
CDialog which is using CWinThread have it s m_pMainWnd point to a CDialog to get the
notifications sent to that CWinThread
Thanks

1. MFC class CWinThread does not have a member of the CAsyncSocket type. Perhaps, you meant that you created a CWinThread derived class which contain a CAsyncSocket derived object?
2. To handle CAsyncSocket notifications you have to override the CAsyncSocket::OnSend, CAsyncSocket::OnReceive and probably other virtual methods. See MSDN article Windows Sockets: Socket Notifications[^]

CAsyncSocket is a member of my CWinThread
Joe Newcomber informed that if I declared the CAsynsocket on the stack instead of the heap I will get notification thru the main thread
Thanks

Well where and how did Joe inform you about it?
|
|
|
|
|
I sent him a e-mail earlier about the problem my workaround was to save the threadid before doing the connect After getting the notification I did a PostThread to the Thread did the connect
Joe said that the reason this Happened (getting the notification to the Main Thread)
Because I had declared my CAsynSocket Class on the Stack e.g. CAsynSocket mysocket.
As opposed to the heap CAsynSocket *mysocket
I haven't tried this out yet

I'm working in MFC under Visual Studio 2010.
I've got my program associated with a file extension and clicking on a file of that type in Windows Explorer will open the program and load that file. All's well so far. Now I need to be able to click on another file of the type from WE and load that file into the same instance of the program already running. What happens now when I click on another file is the focus just switches to the program and nothing loads.
When the program isn't running and you click on a file associated with it, the program starts and in the loading of the App instance you check the command line, which is loaded into a CCommandLineInfo structure and the program deals with the command. I can't figure out how to get the second file to load when the program is already running by selecting it in WE (opening a file from within the program has been working fine from the start).
I have looked at WM_ACTIVATE and WM_ACTIVATEAPP which are called when the program gets focus while running, but I don't know how you would get the information about the file just selected in Windows Explorer. I'm probably missing some key terminology in my searches. I can't find any information on how to do this. Maybe I'm slow kid in class today...
Additionally if I select multiple files in Windows Explorer and open them at the same time, it opens multiple instances of the program instead of opening one instance any loading those files into that one instance. Is there any way to handle that?
Thanks

There are two solutions:
- Implement a COM server for
IDropTaget. - Use DDE.
The first one is the preferred method. See Verbs and File Associations[^].
The keywords from the above link may be used to search for example code (but I did not found something so far; note to myself: might be worth to write an article about this topic).
