It's hard to say why since you don't provide enough information, but there are many reasone that you might see the UAC prompt.
First, if your manifest file has
<requestedExecutionLevel level="requireAdministrator" /> this will force the UAC to appear for any user running the program. You can use
<requestedExecutionLevel level="asInvoker"> which allows the program to run without admin rights, and won't prompt with the UAC...
UNLESS
If your program attempts to perform a Vista restricted function (for instance, writing to a file in anywhere in the Program Files directory) then the UAC prompt will still appear.
Other causes can be the name of your executable file, contents of the VERSIONINFO resource in your .rc file and others.
Check out this thread[^] for more info - especially post #15.
Hope that helps.

What is the priority of MFC application's GUI thread?

Default value is THREAD_PRIORITY_NORMAL
you can use SetThreadPriority() to set desired priority.

Why dont you try your self using GetThreadPriority() function?
|
|
|
|

Thanks for your help!!
I thought these functions of setting and getting thread priority are for only user defined threads, but it seems we can use them for any thread.
But setting priority to GUI thread will work?
Thanks,
Suman

There is nothing called as an user defined thread. There are only two types of threads - UI and worker.

Why not try it?

Hi,
Thanks for your help..
I meant the thread created by user and not applications default one.
Getting or setting priority to application thread is possible, but as Cedric Moonen said, we shold take care when setting priorities.
Thanks & Regards,
Suman

I got it using GetThreadPriority() function inside InitInstance(), it is normal priority(THREAD_PRIORITY_NORMAL = 0).

It's not a answer to your question, but are you really sure that you want to change the GUI thread priority ? If you are still talking about the same problem as yesterday, then I guess that changing the thread priority to avoid a race condition is not the way to go. Besides, if you handle that not correctly you may end up freezing your whole system.
If you use critical section with care, that should solve a lot of your problem (even if you think this will be slower).

Hi Cedric,
Is that just me or nobody's CPMRU will be able to cope with this[^] post? Please tell me that I'm not alone.

Hi,
I asked this to just know and not for any problem.
That problem of race condition resolved already by updating write pointer count only after current write is finish which Pallini suggested.
BTW: My current project consists of many threads, timer, callback from me and other developers, thats why I wanted to know priority level of each.
Thanks for all your help!!

Oh my God! Is it related to this[^]? If yes, you're doing a terrible thing. Please follow the guidance given to you by Cedric.

Hi all,
How can I pass to a string variable the content of an environment variable?
for example
string a;
I want the content of a the value of the environment variable TEMP?
Thanks,
Jayjay

Does this GetEnvironmentVariable(/*parameters*/) help
Somethings seem HARD to do, until we know how to do them.

Thanks Anshuman it works now

Hi,
I am not sure about data type of environment variable, but if you know the data type, you can use CString variable and format it.
Refer here:CString::Format[^]
What compiler are you using?

I have an application which need to start the audio/video settings on a button click. I have written code for that:
************start of code**********************************************
HRESULT hr = CoInitialize(0);
if (FAILED(hr))//CoInitialize failed
return hr;
//Obtain a pointer to the IUccPlatform interface
//by way of the cocreatable UccPlatform class.
CComPtr <IUccPlatform> pIUccPlatform;
hr = CoCreateInstance
(
__uuidof(UccPlatform),
NULL,
CLSCTX_INPROC_SERVER,
__uuidof(IUccPlatform),
(LPVOID *)&pIUccPlatform
);
if (FAILED(hr))
{
AfxMessageBox(IDS_STR_ERROR_COCREATE_INSTANCE);
return hr;
}
CComBSTR bstrAppName = _T("application");
hr = pIUccPlatform->Initialize( bstrAppName);
if (FAILED(hr))
{
AfxMessageBox (IDS_STR_ERROR_INITIALIZE);
return false;
//device settings
}
CComPtr<IUccMediaDeviceSettings> spMediaDeviceSettingsPtr;
pIUccPlatform->QueryInterface( &spMediaDeviceSettingsPtr );
spMediaDeviceSettingsPtr->InvokeTuningWizard((OAHWND)theApp.m_pMainWnd->m_hWnd, UCCTWP_AUDIO | UCCTWP_AUDIO_NONPRIVATE | UCCTWP_AUDIO_NOTIFICATION);
//AfxMessageBox(IDS_STR_ERROR_INVOKE_TUNING_WIZARD);
pIUccPlatform->Shutdown();
*****************End of Code************************
and as I know we have to add the three dlls(UCCAPIRES.dll,UccApi.dll,RTMPLTFM.dll) in application project, I have done that and I also got success in that. But when I run my application on other system after clicking button to start the audio/video settings I got an error message "Error CoCreateInstance ".
If any idea then please share.
Configuration for apllication is
WindowsXp
