i have a structure, call

<br />
struct FileType<br />
{<br />
  char type[_MAX_EXT];<br />
  char size[20];<br />
   <br />
};<br />
<br />

and the text file that looks like

.txt 4140
.tif 4100
.doc 21000
.pdf 3459
.
.
.

so i want to read from the text file and put it into array.
so used vector.

<br />
#include <vector><br />
typedef vector<TypeSize> typeNsize;<br />
<br />
  TypeSize typeNsize;<br />
<br />
  ifstream filelist("TableOfType.txt",ios::in);   //open TableOfType.txt  <br />
  while(!filelist.eof())<br />
  {<br />
    filelist>>typeNsize.filetype>>typeNsize.size;<br />
    <br />
  }<br />
  filelist.close();<br />

my application is dialog base.

and i have following errors

<br />
<br />

<br />

i was thinking to use CStringArray like read the sentence like

<br />
char info[50];<br />
filelist.getline(info,50,'\n');<br />
CString infoline = (const char*)info;<br />
CStringArray array;<br />
array.add(infoline)<br />

if i do so , i have to separate the string into two parts, type and size, again. i dont' want to do that..
do you have any idea better than what i have right now?

Try this

================================================
#include <iostream>
#include <fstream>
#include <vector>

using namespace std;

/*

Other code here

*/

struct FileType
{
char type[_MAX_EXT];
char size[20];

};

/*

other code here

*/

vector<FileType> v_filetypes;

ifstream filelist("TableOfType.txt", ios::in); //ios:in is optional

while(!filelist.eof())
{
filelist >> v_filetypes.type >> v_filetypes.size;
}

filelist.close();

================================================

That should work fine... I think.. but my brain isn't working the best Smile | :)

CView border

Does anyone know how to remove a sunken style border from a CView? When I use ModifyStyle and ModifyStyleEx on it removing the border flags on it, it doesn't seem to make any difference? Does anybody know a way around this problem?

Joel, have you tried changing the style in: CJoelsView::PreCreateWindow(CREATESTRUCT& cs)?

After you change the style of a window, you need to call SetWindowPos in order to force a repaint of the frame. make this call:

::SetWindowPos(hWnd, NULL,0,0,0,0, SWP_NOMOVE SWP_NOSIZE | SWP_NOZORDER | SWP_FRAMECHANGED | SWP_NOACTIVATE);

BTW, this is in the documentation for SetWindowLong.

Good Luck

I've just written this line of code:

CFrameWnd *fw= (CFrameWnd*)AfxGetMainWnd();

It lies in the OnCreate handler of a docking window, but for some reason the pointer returned by AfxGetMainWnd is not the expected CFrameWnd, but a pointer to a CToolTipCtrl Confused | :confused:

. This I don't really understand. Does anybody know why the problem occures, or how to fix it? Thanks for your time.

How do you know it is pointing to a CToolTipCtrl? As an aside it isn't a good idea to use the old C style casts. In this case use a dynamic_cast.

Is the OnCreate running in a seperate thread to the main app code?

Basically all it does is to return the m_pMainWnd member! You sure you are not meddling with m_pMainWnd soewhere else?

Hello,

I've just read an article here saying how to enumerate the data in windows' protected storage.

http://www.codeproject.com/w2k/pseenuma.asp

I can't understand , without having a COM calss being registered, declared and Created at runtime, how are we able to access its methods and properties?

I would be glad if anyone can give me an example for doing this. Smile | :)

hi.. all
i have a function that travel the file tree( like window explore ), get the tree item, calculate the file size, and estimate how many page will print. and print to the .txt file.
the function is doing ok. it is fast when estimating all files( let's say 1000 files). but for 12000 files, so.. slow. for 35000 files, even worst. it took 10 minues to finish all travel, get file size, do caculation, and write to the file. i found out for that 35000 files, the txt file has 238 pages, which is the reason it took 10 minues, i guess.

here how i print to file.
1. open file -> ofstream file; file.open("c:\estimated.txt");
2. do estimate-> get file size and calculate
3. print to file -> file<

Are you opening the file each time you write to it? If so, you might consider keeping the file open for the duration of the whole scanning process. This should speed your app up by orders of magnitude.

If your opening the file each time then that woudl slow it down. Just open at the begining of your app and close at the bottom.

ofstream outFile("estimated.txt");

and then close it Smile | :)

pnpfriend1-Jun-02 7:52

yes.. i do open the file very top and close it after tree travesal, and calculation for all has finished.
but thanks i have another file which is getting the size of the file open and close for each file. i will put that into array and read it from array. hope that will speed my estimate page function.

thanks guys

Try using a vector... itmight work quicker than an array. Especially if your filling it with lots of info... and it's dynamic too [and genreic] Wink | ;-)

wow!!!
i use cstringarray to store files types and sizes
as follow:

<br />
char info[50];<br />
CStringArray array;<br />
ofstrea filelsit.open("type.txt");<br />
while(!filelist.eof())<br />
{<br />
filelist.getline(info,50,'\n');<br />
CString infoline = (const char*)info;<br />
array.add(infoline)<br />
}<br />

guess what it only tooks 16 sec to read and estimate page to print for all 350000 files.
compare to old function, way way faster. old function took 10 mins and now only 16 sec.
i say WOW WTF | :WTF:

let me try to use vector.. i think vector might be faster because i dont' have to separator type and size again.
