Do you mean that you cannot hard code that path? Can you please clarify?

The standard way is to use the SHGetKnownFolderIDList()[^]function by passing the REFKNOWNFOLDERID as FOLDERID_Public. This function is available only in vista and in you case since you cannot install latest SDK, you have to dynamically load the function from the shell32.dll.

How ever I think the following code will also work( I didnt test it because i dont have vista right now )

TCHAR tcPath[MAX_PATH];
GetEnvironmentVariable( _T("PUBLIC"), tcPath, MAX_PATH );

Yes, by clicking outside the edit box. $Shucks | :-\$

or you can explicitly set focus to some control other than the edit box after setting it first on the edit box. ON another note, OnKillFocus is called by the framework, when the control looses the focus.
or
Try SendMessage with WM_KILLFOCUS as one of the params (Just a guess)

Hope this helps..

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

If you click button then the focus will be set to button. So the OnKillFocus of editbox will be called, provided you have mapped like
ON_EN_KILLFOCUS(IDC_EDIT1, OnKillFocus)

Did you declare OnKillFocus for editbox?

Simply map "OnKillFoucus" to the click event of button

ON_BN_CLICKED(IDC_BUTTON, OnKillFoucus)

i am having problem with sscanf being how I say o.O

line exactly

<br />
"spawn = 1648\t3409\t3536\t0\t3410\t3557\t3408\t3535\t2\tCow"<br />

the code I use

struct Pos {
	int x;
	int y;
};

int npcId = 0;
Pos coords;
int heightLevel = 0;
Pos moveRange1;
Pos moveRange2;
int direction;

sscanf(line,"spawn%*[ ]=%*[ ]%d%*[\t]%d%*[\t]%d%*[\t]%d%*[\t]%d%*[\t]%d%*[\t]%d%*[\t]%d%*[\t]%d",&npcId, &coords.x, &coords.y, &heightLevel, &moveRange1.x, &moveRange1.y, &moveRange2.x, &moveRange2.y, &direction);

"spawn = 1648\t3409\t3536\t0\t3410\t3557\t3408\t3535\t2\tCow"
outputs =
npcId: 0 (has to be 1648) (wrong for no reason o.O)
coords.x: 3412
coords.y: 3536
heightLevel: 0
moveRange1.x: 0 (wrong for again no reason as the format pattern matches)
moveRange1.y: 3557
moveRange2.x: 3408
moveRange2.y: 3535
direction: 2
the last \tCow is to be ignored its not really needed.

So whats wrong really Sigh | :sigh:

I now its right.. because I used the same code.. just a little modified for another part of loading files.. and it works perfectly.. but this.. doesn't.. i should post full method can u try it?. I believe my error is divine intervention because god doesn't want me to become a programmer.

BTW, first you should identify which line of data is having the error. Did you try so?

Well it obviously does or you would not be asking for help. Use the debugger.

Debugger isn't helping what do u think I've been using this whole time before I posted question.. it just breakpoints on 1 line.. i see everything inside sscan the tokens and such... I even see the npcId value but it doesnt set up inside the npcId datatype.. which remains zero................................. WTF | :WTF:

How could I possibly know the answer to that since you never mentioned what you tried?

As someone that helps on this board FOR FREE AND IN MY SPARE TIME, my assumptions are based solely on the information, or lack thereof, that you provide. If you want us to know something, tell us.

If you replaced the 0 in line to some other number, what value would moveRange1.x have?

Cbadboy wrote:
So whats wrong really

How about coords.x having a value of 3412 instead of 3419?

What does sscanf() return?

Which means you had a short int.

No such difference exists.

Try the CArray class in the MFC and if you dont use MFC, check the vector class.

You can also approach in STL way with std::string/std::wstring with containers like vectors, deque, list etc...

e.g vector<string> arrString; defines a string array in STL way. you can also approach other containers based on your use. Probably a vector will do.
