I tried it and it seems to work..

char* tst = "hkjsdh\\ks\\dj\\sdsdsd\\sfssf\\sfsfs";

for (int i=0; tst[i]; i++)
 {
  if (tst[i] == '\\')
     printf("[backslash]");
  else
     printf("%c", tst[i]);
 }

I suppose the bug is somewhere else in your program?

Try this code out :-

char *p=abc; //abc has full path
while(strchr(p,'\\'))
{	
	p=strchr(p,'\\');
	p++;
}
MessageBox(p); //p has filename

Are you required to write this yourself? If not, then use PathFindFileName() in shlwapi.dll. Otherwise, use strrchr() to find the last backslash.

char* pLastBkslash = strrchr ( szPathName, '\\' );
char* pFilename;
 
  if ( NULL != pLastBkslash )
    pFilename = pLastBkslash + 1;

That assumes that there is only one slash???
Or did it implicitly imply that the guy has to repeat that till he gets the last backslash?

I used strrchr (notice the extra 'r' meaning "from the right") which finds the last occurrence of a character.

If i'm clocking code speed using QueryPerfomanceCOunter()
would it be more accurate if if set the current process/thread to a highest priority...?

Windows time slicing gives so much exec time to each process higer the priority = more time...?

This would mean less likely an interuption correct...?

Thanx!

p.s.I just d/l 34 Mb file in less than 3 minutes Shaw cable...Incredible... OMG | :OMG:

Take a look at the CPUTest article, it's related to your question. Most of the people tried it said it's better at real time priority. Just make sure you set the priority back to normal after the loop you want to clock

I would figure

cs.x = FIXED_SIZE;
cs.y = FIXED_SIZE;

Although i dunno if this is enough...I'm thinking you'd probably control fixed sizes in OnSize.

Maybe returning false in PreCreateWindow would work, i dunno i'm too lazy to try it out first... Poke tongue | ;-P

Sorry man I must correct myself.

I thought you were after only resize to a fixed size then hault.

But if all you want is a fixed size...

cs.cx = FIXED;
cs.cy = FIXED;

cs.style = WS_DLGFRAME;

However you could probably use Onresize to control this agin, but it's unessecary..

FIXED or FIXED_SIZE are undeclared identifier,and compiler return error.
And there is one problem with "cs.style = WS_DLGFRAME;"
,the minimize,close buttons(I mean system menu) disappear?
thanks

Oh God, someone help me.

Can't you tell that the variables being shown to you define the window size and need to be inserted by you ? He's showing you where to put the size you want.

For the caption you need to add the style bits for the system menu, etc. I don't recall them exactly, but it's something like WS_SYSMENU. Try msdn.microsoft.com to get a list of them. Actually, the better way to do it is take the old value, strip the style that you want to lose and then add the one you want. For exmaple, to remove WS_SYSMENU, you do this: myStyle &= (~WS_SYSMENU); I am presuming myStyle is a variable to which the old style has been stored.

I'll help you Christian Laugh | :laugh:

this was my code:
cs.style = WS_DLGFRAME;
cs.style = WS_OVERLAPPED | WS_CAPTION | FWS_ADDTOTITLE
| WS_THICKFRAME | WS_MINIMIZEBOX | WS_SYSMENU;
cs.cx=cs.cy=600;

Here there is one problem and user can "RESIZE" the frame,of cource I have
system menu at this case,if I put WS_DLGFRAME at the end then I can't resize it but I don't have minimize and system menu.
At last I solved it with this:

cs.style = WS_OVERLAPPED | WS_CAPTION | FWS_ADDTOTITLE
| WS_THICKFRAME ;
cs.cx=cs.cy=300;

cs.style = WS_DLGFRAME;
cs.style=WS_SYSMENU| WS_MINIMIZEBOX;

and everything is ok now
thanks toboth of you

Now you DO realise that two of these four lines of code are useless, don't you ?

I'm not sure if this will work, but I suppose you could get the IHTMLDocument2 interface (CHTMLView::GetHtmlDocument), put the data in an SAFEARRAY and use IHTMLDocument::write to put it in the document.

Seems like you can. Found this article while writing the reply:
