how can i speed up when loading files? it's no sense that it takes so much times.
|
|
|
|
|
is it a C++/MFC programming question ? or an Operating System question ? or a General question ?
what takes a long time ? showing the file dialog or loading the file itself ?

open the file itself. it's not a programming issus

Wich are your machine specs? And AuctoCAD version? Besides, is it Windows XP or Windows 2000? =$
If you don't have much RAM memory, then having all those files on the same directory is not a good idea.. That's probably why it is crashing.
Also notice this is a Visual C++ / MFC forum.. Next time choose the appropriate forum for your posts.

I write a programm with C# and it's ok. But with Visual c++, I have the error: "include 'ATLComTime.h' not found. I add it in my project, but ich get new errors like the first one.
Why can i do to eliminate these errors?
Thank you.

didn't you forget the #include its header in the file that's using it ?

Hã? You can't compile C# with a C++ compiler... But if the problem is an #include directive, then try adding the file's path to the "directories" list. Access Tools | Options and then click "Directories". But I'm not shure that's what is happening to you.

I'm Creating an ActiveX subclassing "EDIT". I would
like it to be able to change the colour of the background, text or indeed
both.
I've added the BackColor and ForeColor as Stock implementation.
I've changed below:
BEGIN_PROPPAGEIDS(CEditTestCtrl, 1)
PROPPAGEID(CEditTestPropPage::guid)
END_PROPPAGEIDS(CEditTestCtrl)
to
<CODE>BEGIN_PROPPAGEIDS(CEditTestCtrl, 2)
PROPPAGEID(CEditTestPropPage::guid)
PROPPAGEID(CLSID_CColorPropPage)
END_PROPPAGEIDS(CEditTestCtrl)
</CODE>
I've also modified the OnDraw method to;
<CODE>void CEditTestCtrl::OnDraw(
CDC* pdc, const CRect& rcBounds, const CRect& rcInvalid)
{
DoSuperclassPaint(pdc, rcBounds);
pdc->FillRect(&rcBounds, &CBrush(TranslateColor(GetBackColor())));
}</CODE>
The Bakground colour changes. The problem lies when enter text in the control, the control reverts back to the orignal colour.
The question is what is the correct way in achieving this?

Hello Alton Williams,
I don't have answer to your question but i just want to know why are you doing this through ActiveX control. I mean you can change the background and text color of standard Edit control by Handling WM_CTLCOLOR Message. Is ActiveX your requirement?

}
Use pdc->SetBkMode(TRANSPARENT) to make text background transparent.

I need to verify that the outputs from two separate builds, using the same source code, is equivalent. If I compare the DLLs, there are 13 bytes that are different. Is there a tool somewhere that can do this kind of comparison?
Thanx,
Steve

Use fc /b file1 file2 from a command prompt.

I've tried that. There are 13 bytes that are different. I can see no reason for them to be different since the source code is the same and the same version of Visual C++ is being used. Is there a build date or something in the DLL that would cause the miscompare? If so, is there a way to ignore it?
Thanx,
Steve

I think I read somewhere in the PE literature about the linker writing date-related information to the file. It should be the number of seconds since December 31st, 1969 @ 4:00 P.M.

I wrote a small code to read a file and write it out. I found the program can not read all the lines. I do not know what is wrong ? Please ckeck it for me.
---------------------------------------------------------------------
// blast_vib_procDlg.cpp : implementation file
//
#include <iostream.h>
#include <fstream.h>
#include <string>
using std::string;
int
main()
{
// read seed waveform data file
// string qq;
char filein[35];
char fileout[35];
ifstream f_ptr1;
ofstream f_ptr2;
char buffer_seed[90];
int i=0;
//
string pp;
cout << "input file name ?";
cin >> filein;
cout << "output file name ?";
cin >> fileout;
f_ptr1.open(filein);
if(!f_ptr1) {
cerr << "error: unable to open input file: "<

How many lines are in the file? The while loop terminates when it encounters a \n character. Is this intentional?

I am using VC++ compiler.
My intention is to read a file completely. So my intension is to read until
the end of the file. I do not know what is the best symbol to put at
while(!(qq=="'\n'")). I tried a few different symbols, does't help.
Thanks

I think you need to use the eof() method instead. Something like:
while (! f_ptr1.eof())
{
f_ptr1.getline(...);
f_ptr2.write(...);
}
On a side note, are ruilin Yang and mrby123 one in the same?

Hi DavidCrow
You solved my problem. ruilin = mrby123
Thanks
By the way, I do not like the f_ptr1.getline (par1,par2,par3); I do not like to
specify the number of the characters or the third parameter ' '.
I like to use the string function: getline(f_ptr1,s), This looks more robust,
but it does not work. The compile do not know the function, even you can see
I have #include string
The program is funny, when I put #include iostream and #include fstream
I got :'ifstream' : undeclared identifier
I have to put: #include iostream.h and #include fstream.h
Then the program works. I do not understand why I can not use #include iostream.
