Do you want to set the Mouse Cursor in your application to hand/hourglass etc? See SetCursor with IDC_HAND etc

Somethings seem HARD to do, until we know how to do them.

Thanks for your reply
But i don't want to set Cursor, i want to get it.
i.e. Whenever the Cursor changes from one type to another then my application should come to know that now cursor is changed and with which type.

Is this possible?

I think the handle to system cursor return from LoadCursor(IDC_WAIT/...) return the unique same value everytime for the same cursor.

u can compare the handle to the handle returned from GetCursor.

and also i think u can compare that at WM_SETCURSOR notification.

but why u need to know the state of app from the cursor, normally u will be setting the cursor for ur application, then u are able to know the current cursor without quering from the cursor.

No this is not the case.

I am developing application for screen sharing.

In that i want to pass the type of mouse cursor just like (HAND, HELP, WAIT,...)
I can also get the HCURSOR handle and by comparing it with inbuilt type i am getting cursor, but problem is with application that uses custom cursors like flash uses.

So is there any other alternative then this one?

CURSORINFO cInfo;<br />
  cInfo.cbSize = sizeof(cInfo);<br />
  if(cInfo.hCursor == LoadCursor(NULL, IDC_HAND))<br />
  {<br />
     // For Hand Cursor<br />
   }

This works fine when cursor is of system type
Now it will broken when i use it with flash because flash uses custom cursor so cInfo.hCursor will give some long values.

Now i think you should understand my problem.
If is there a way to know the type of cursor just like this is a cursor of type hand

Thanks for your kind reply
please help me on this.

Thanks

I would like to know why u need the type of cursor,

if u want to use the same cursor on different process, use the handle, it is shareable among process [^], to use on different machine u can pass the image of cursor (for once).

if u want to identify the type of cursor and there by determine the state of application, it is upto the application, for instance i can use WAIT cursor to indicate the purpose HAND.

what about adding the exe as resource.

ya excatly, do u know any thread in codeguru????

Rajkumar R20-Feb-08 20:14

20-Feb-08 20:14

u can search for it,

but actually it is very easy,

1. add the exe as custom resource
2. load the resource LoadResource()
3. Get the buffer pointer to the resource using LockResource().
4. Then save the data to a file.

if u refer the api u will get the example code.

Try looking at the top of the web page. You see the logo of an alien? What do the words next to it say? In big letters?

If you want to know about threads on codeguru, then you might be better *asking* on codeguru.

I'm pretty sure there are articles all about embedding and extracting abritrary resources in executables here on codeproject but apparently you are not interested in them...

I have no problem with people asking for help - what you're trying to do is not easy. I helped someone with a very similar problem last week, so please look back a few days for my name in a chain conversation.

It just amused me that you were posting on codeproject asking about threads on a different website!

Hi Experts,
I am filling a file content with Zero and renamed it and Delete it.
but when I rename the file and try to delete it, file file's lost contents are come back.
If I do not Rename the file everything is fine.

Its like
1.Fill content with Zero
2. szString=RenameFile(szString)
3. DeleteFile(szString);

But I put a Sleep(2000) in between 2 and 3 It works well but get slow.

Is there any workaround?

Thank You.

You have to close the file handle first!

CopyFile("Src.txt", "Dest.txt", FALSE);
DeleteFile("Src.txt");

rename("Src.txt", "Dest.txt");

CopyFile() create another copy of that file. I do not want to create any other copy of this file.

Actuelly we want to delete the actual file not Copied file.
