I am changing certain registry keys using VC++ and after that I want to refresh explorer. I have tried following two ways but none of them works under vista.
1. SHChangeNotify(SHCNE_ASSOCCHANGED, SHCNF_IDLIST, NULL, NULL);<br />
2. SendMessageTimeout(HWND_BROADCAST, WM_SETTINGCHANGE, 0, 0, SMTO_NORMAL, 1000);
Is there some other way to refresh explorer under vista?

Hi all,
i have coded one 8 KHz 16 Bit PCM audio with ITU's G.729A codec. now i want Media player to run the coded file. I'll be really thankful if somebody helps me filling WAVEFORMATEX structure so that RIFF header can be append with the coded file.
Thanks

Hi,
I have some application that i wrote as doc/view architecture.
In this application i pop up some child window using DoModal.
The child windows is up and the application need to ignore all the action that i doing on the main window ( because of the doModal of the child window ).
But - actually - when i try to minimize the main window i find out that the application not ignoring the minimize command and the application is minimize.
How its can be ? how can i solve this problem ?
P.S: the minimize is done by doing a lot of clicking on the minimize button on the title bar. If clicking only once - nothing happened.
Thanks.

I am not sure but, I think It could be a reason some time main window is getting the message while the modal dialog not getting.
May be very rare.
Thanks,
Suman

Its obvious that the main window got some message - but how its can be ? and how it can be solved ?

this is the programming for the image conversion...let say, i want to create a loop for this command...how i want to do it?

First of all, please, use <pre> tags around code snippets.
Why don't you wrap that code inside a function and then iteratively call it?

Because that adds the cost of a function call to every pixel that is processed ?

Hello,
I have made a dll of my classes and using them in a project. The project compiles properly but when I try to execute the project the behaviour is wierd.
The classes otherwise (without dll) are working as expected.
what must be the reason?

Hello,
Thanks for all your replies.
The classes are working fine.Now when I make dll of them and include that dll for a client project the classes don't behave as were behaving earlier.
For ex I have a code
int Parent=0;
for(int i=0;i<10;++i)
{if(mstruct[i]=="Parent")
++Parent;
else
--Parent;
}
Now even if mstruct[i] = "Parent" the compiler moves to Parent--.
In my code (without dll )I would get ++Parent.
What must be the reason?
Thanks for your co-operation
Pritha
