I have been racking my brain for a while now trying to make my program track down the size of a folder/file. I would like to track how much space a folder is using on the hard drive, which I have determined that means recursing through the sub folders and adding up the size of all files... Ugh! Is there an easier way? If not, the problem I'm running into at this point is simply finding the size of the file! I've looked into every which way of find the file sizes and they all want some variable/handle that I don't have... I've been looking through the code for the tree's here and have found some very nice tips and stuff, but of course (as always) they are in dialog boxes with special controls, yadda yadda yadda. (Doesn't anyone else use MFC with a doc/view?) But I'm not seeing how to add up the size of files and stuff. Please, someone help me out. I'm getting frustrated to the point that I can't even explain it right

G'Day Greven,
Maybe I have mis-understood what you are trying to do but you can use CFindFile to recurse sub directories. CFindFile has a member function GetLength() which returns the size of a found file. So it is easy to step through a directory and work out its size
something like will come close (cut and pasted from existing code so I may have chopped some bits out but you should get the drift)
TraverseDirectory(CString strDirectory)
{
int nBytes = 0;
BOOL bWorking = finder.FindFile(strDirectory);
while (bWorking)
{
bWorking = finder.FindNextFile();
strFileName = finder.GetFilePath();
if (finder.IsDirectory())
{
if (!finder.IsDots())
TraverseDirectory(strFileName);
} else {
nBytes = finder.GetLength();
}
}
You can also use GetDiskFreeSpaceEx to determine free space information.
Hope that helps.
Richard.

That is exactly what I have been looking for... Thank you very much. And you know the worst part? I've used CFindFile many times before... Just never noticed the GetLength() function... (maybe it's just a really bad name for it

You can also use CFile::GetStatus() to get the size of any file.

Hi there
I have MDI application.
Child MDI window consists of CMDIChildWnd and CView.
What events and what situation I should handle in
CMDIChildWnd and what I should handle in CView?
Second question, if I need to change size of CView then
I have also change
size of CMDIChildWnd, is it true?
In CView I inserted CPropertySheet and I need to make size of child MDI
window the same as size of inserted CPropertySheet, what is the right way to do it?

Hi,
I have a complicated (to me) problem reading/Writing data in binary. Here is what I am doing.
For example let say a text file has the following:
File: test.txt
-----------------
1234a5678b9
-----------------
Here is what I am doing:
istream inData;
ostream outData;
inData.open("test.txt", ios::in | ios::binary);
outData.open("modified.txt", ios::out | ios::binary);
inData.seekg(0, ios::end);
int size = inData.tellg();
char *temp;
temp = new char[size + 2];
inData.read(reinterpret_cast<char *="">(temp), size);
temp[size + 1] = 'c';
temp[size + 2] = 'd';
outData.write(reinterpret_cast<char *="">(temp), (size + 2);
-----------------------------------------------------
The code above should work okay. As you can see, all I am doing is reading data from a file, add two characters "c" and "d" and then writing it back to the file. Everything is fine.
Now, let say I read the modified file back.
Here is what I am doing:
istream modData;
ostream weird;
modData.open("modified.txt", ios::in | ios::binary);
weird.open("hungry", ios::out | ios::binary);
inData.seekg(0, ios::end);
int size = inData.tellg();
char *temp, charA, charB;
temp = new char[size];
inData.read(reinterpret_cast<char *="">(temp), size);
charA = temp[size - 2];
charB = temp[size - 1];
-----------------------------------------------------
Do you see what I am trying to doing?
1)read fileA in binary
2)save data from fileA to tempX
3)add characters to tempY
4)write temp to fileB
-----------------------
1)read fileB in binary
2)save data from fileB to tempZ
3)extract ONLY those characters I added to tempX from tempZ
-----------------------
The method I use to extract the added characters from the modified file after I read it back is subscript. I assume let say temp[5] is 'a'. When I read the data back, I look at temp[5].
My question is when you read a file in binary, add characters to it in specific spaces and write it to modified file, is it possible to read the data from the modified file and extract those characters you added via assumption subscript? How are data saved when you read and write in binary?
Thanks,
Kuphryn

I see some problems with what you are doing.
First, arrays are zero-based. To append two characters to the end of an array of size means you write to temp[size] and temp[size+1]. The write command with (size+2) is then correct. Accessing [size+2] means you must allocate and write (size+3) items. The last of the original data will be at index (size-1).
To extract only the characters you added then seek to position size on your input stream and then read 2 items.

Interesting. Thanks.
I got everything write. When I read teh modified data back, sometimes it comes out right and sometimes it does not. I do not know if it is writing the modified file differently everytime.

Is possible to rebuild IntelliSense ASC stores found in <msvs-root>\Common\MSDev98\Bin (Win32.ncb, Mfcatl.ncb and Crt.ncb) ? Simply deleting them only disables code editor's IntelliSense features 
I'd needed to recreate them because they contains in some instances improper data, f.E. incorrect number of function parameters, wrong return type etc. - it could be very confusing.
Does anybody know how to solve this problem or knows something about internal format of .ncb files ? I know there is a good replacement called Visual Assist from WholeTomato software but it isn't free
Thx

If you have a network (LAN), go to your network connections in Control Panel and right click on the Local Area Connection (or whatever you have there). You can make it "Enable" or "Disable" (connect or disconnect). Now my question is how to do this programmatically in Windows 2000? I was looking in MSDN and didn't find nothing.... Change user info, get domains.... all what you want but not something like Connect or Login.
IF someone knows the answer, please tell me
Thanx
Philip Patrick

if you are asking about #ifndef then the main difference is the #if form permits complex expressions such as :
#if( !define(THIS) && !define(THAT) && !(THE_OTHER_THING) )
I don't believe that #ifndef supports this type of expression. It may but I have never seen any.

- Thanks pal!
- I think the statement "#if( !define(THIS) && !define(THAT) && !(THE_OTHER_THING) )" should be
#if( !define(THIS) && !define(THAT) && !define(THE_OTHER_THING) )
- Am I right?

Yep, I missed that last define.
I was just testing you. 
Actually, they should all say defined but your compiler would tell you that soon enough.
Good Luck.

_DEBUG is the standard definition that VC++ uses when performing a debug build. I don't know about DEBUG. I couldn't find it in the docs.
