Multiple Writers with IStorage

I am having problems using the IStorage interface with multiple writers. I've reviewed and used all the info on MSDN regarding these but regardless if I have two writers at the same time, I lose the changes of one.

In particular I've noticed problems using multiple writers and TRANSACTED mode, I was wondering if anyone has done any work with this?

Specifically, if I have two writers open the storage at the same time and the modify two different streams or sub storages, the writer that closes the storage last keeps their changes. It does not seem to matter what flags I specify and I can't seem to get this working with multiple writers. If you have any suggestions please let me know.

Thanks,
Dustin

am i using sockets correctly?

<br />
class CMySocket : public CAsyncSocket<br />
{<br />
public:<br />
	CMySocket() : CAsyncSocket() {}<br />
<br />
	void OnAccept()<br />
	{<br />
		_tprintf(_T("incoming connection\n"));<br />
	}<br />
};<br />
<br />
//and then later<br />
<br />
if( !AfxSocketInit()  )<br />
           _tprintf(_T("Cannot init sockets"));<br />
<br />
		CMySocket* sock = new CMySocket;<br />
		if( sock->Create(1935,SOCK_STREAM,FD_READ | FD_WRITE) )<br />
			 _tprintf(_T("Created!\n"));<br />
		if( sock->Listen() )<br />
             _tprintf(_T("Listening!\n"));<br />
delete sock;<br />

the thing is that listening doesn't seem to get aby results though another app connects to that port. i am sending data from my FLASH movie via XMLSocket object but no result Frown | :(

Inflate EXE on startup

Some time ago when it was common that an application/game came on a single diskette one way to make it fit was to compress the executable and then inflate it on startup into memory.

Is something similar available for Win32 executables?

Thanks Andre

Receiving a RPC_S_SERVER_UNAVAILABLE (1722) Error After Calling GetEffectiveRightsFromAcl

Edward Abrahim2-May-06 9:57

Hi All,

The project I am working with is a Win32 in Visual c++ 6.0.
I am calling the API GetEffectiveRightsFromAcl:

dwResult = GetEffectiveRightsFromAcl(
ppDacl, // PACL pacl,
pTrustee, // PTRUSTEE pTrustee,
&dwAccessMask // PACCESS_MASK pAccessRights
);

It is returning with error code 1722 (RPC_S_SERVER_UNAVAILABLE).

The parameters ppDacl and pTrustee seem to be set properly.

Other APIS, such as GetExplicitEntriesFromAcl and LookupPrivilegeValue can be called with no errors returned.

Any help is appreciated.

Edward

Subclass the button and handle the WM_RBUTTONDOWN and WM_RBUTTONUP messages. There are several articles on subclassing controls here on CP, just do a search.

The preferred way is to handle WM_CONTEXTMENU, that way the user can get to your right-click feature using the keyboard as well.

When to create Dialog-based app and when to use normal window ?

I'm trying to decide when it's best to use a dialog based app and when to use a normal window.

What are the advantages and disadvantages of both methods ?

What basic rules should I use to decide which method to use ?

Just found the following article by Nish

http://www.codeproject.com/dialog/pretransdialog01.asp

which indicates a key difference "...is that in a dialog based application the focus is always on one of the child controls and not on the main dialog window."

He also gives a couple of ways to handle keyboard messages and accelerators.

Aside from this, are there any other big differences ?

What do you mean by a normal window ? A dialog box is also a normal window Smile | :)

.

Are you speaking about the SDI (single document interface) framework ?

Re: When to create Dialog-based app and when to use normal window ?

Defenestration2-May-06 9:52

I mean a non-dialog window (eg. SDI or MDI). Smile | :)

Then it depends of the complexity of your program. The advantage of SDI/MDI apps is that they have the document/view architecture that can help a lot writing complex applications. But also, if you have a very simle app (two buttons and an edit box for example Poke tongue | ;-P

), then it is a little bit overkill.

Of course, I'm speaking here about a SDI (or MDI) app when the view class inherits from a CFormView (to have a something similar as a dialog box).

Also, what I forgot to say is that SDI/MDI apps offer more support for toolbars, menus, serialization, ...

You have to be way more specific. How is your image stored? How are you reading it in?

to be more specific here matrix means a two dimensional array of interger,

here we have to find the intensity of each pixel and store then int he array

for example consider an image with resoultion 5x5 if the intesity of
0x0 pixel is 10 and 0x1 pixel is 20 then

the matrix will be
10 20 .. .. .. ..
.. .. .. .. .. ..
.. .. .. .. .. ..
.. .. .. and so on
