Re: [Dev-C++] dynamic allocation and structs

[Per W. <pw...@ia...>]

Well, maybe not directly forever.

It will also be automatically released - for most operating systems, that
is - when the application ends.

Re: AW: [Dev-C++] Strange phenomenon

[Daniel G. <sp...@ho...>]

Do you need to use BYTE? you seem to be typecasting a lot.
You've allocated memory with new
BYTE *CalledPartyNumberStruct = new BYTE[1024];
then used malloc to allocate more memory later, why is that?

[Dev-C++] dynamic allocation and structs

[Scott W. <se...@al...>]

Hi,

I'm working in C (no C++ please).  Got a couple of questions related to
dynamic allocation and in particular, dynamically allocating an array of
structs.

First, what is the duration of memory allocated by malloc (etc.)?  In
particular, I want to dynamically allocate/de-allocate several global
variables within a single subroutine called from main and so want to be sure
that the allocated memory exists beyond the scope of that subroutine.

Second, it is my understanding that it is perfectly acceptable to have an
array of structs.  E.g.,

struct mystruct {
  double var1;
  long   var2;
  etc...
}

. . .

struct mystruct data[100];

Is this correct?  If so, what then is the calling sequence to dynamically
allocate an array of structs, and, in particularly, make the result
available globally?

Thanks for your help (& sorry if this is naive).

Scott Williams

I tried to store all the info in a linked list, but I think I did something
wrong because the program just froze when I tried to draw something. Then I
thought it would be easier to store the drawing in a compatible memory
bitmap and then just copy it back in the client area when it needs to be
redrawn, but this also didn't work because the program froze again. That's
why I was asking if anyone can give me some guidelines about how to do this
(the bitmap way).
As for the tutorials, I read the book "Teach yourself VC++ in 21 days" which
also has some stuff about this, but although I think I did everything the
way it's done in VC++- it doesn't work.

[Dev-C++] Strange phenomenon

[Christian W. <Chr...@vo...>]

Hi List,


i have a strange phenomenon in my project:

I call a function: Test(char szTest[1024]) with Test("test");

In that function another Function (like the first) will be called:
Test2(szTest);

the adress of szZest is 0x000000000....

and the content is empty ....


Anyone an Idea ????

Kind r

Chris

RE : [Dev-C++] How to keep the DOS console open?

[Pierre L. <fam...@gl...>]

You must send a command to DOS to pause for sometime.

The solution look like this :


#include <cstdlib>  // function system


=85

void main {

=85 your programm

 system(=93PAUSE=94);

} // end of main.

Re: [Dev-C++] Whoops - drawing in Windows

[Daniel G. <sp...@ho...>]

Nope maybe not, serialising is for saving and restoring.

I think you have to store the info in to an array, but looking at this old 
code I cannot remember what exactly you have to do. I worked on the Scribble 
tutorial that comes with VC++ - have a look on MSDN for it.

Re: [Dev-C++] drawing in Windows

[Daniel G. <sp...@ho...>]

Yes you need to serialise the information to a file. I'll see if I can dig 
up some information on this, but that's what you need to do.

Re: [Dev-C++] Input one file output another.

[Daniel G. <sp...@ho...>]

This constructor may help
fstream( const char* szName, int nMode, int nProt = filebuf::openprot );

szName is the name of the file,
nMode is ios::in, ios::out etc.
then use
filebuf::sh_read   (Read sharing allowed.)
and
filebuf::sh_write   (Write sharing allowed.)
with the || operator.


Try closing the file as well once you are done with it.

[Dev-C++] drawing in Windows

[Vlada D. <dj...@im...>]

Hi, everybody
Here's my problem: I'm trying to write a simple drawing app (just for =
exercise) and so far its been going OK. I can draw lines in client area =
in different colors, but when ever I minimize or maximize the window, or =
something similar happenes, all the content of the window is gone. I =
tried to use a memory DC an bitmap to save the contents in, and BitBlt =
it back in response to WM_PAINT message, but the program just "froze". =
Can anybody give me a hint how to do it? Here's the code used for =
drawing lines without any restoring parts:

        case WM_MOUSEMOVE:
        {
            switch(iTool)           /* iTool is used for dtetrmining =
which drawing tool is selected(line, rect etc.)*/
            {
                case 0:
                {
                   if(wParam=3D=3DMK_LBUTTON)    /*if line is selected =
(itool=3D0) and left button presed*/
                   {
                         HDC hDC=3DGetDC(hwnd);           =20
                      =20
                       HPEN =
hPen=3DCreatePen(PS_SOLID,iCurWidth,crCurColor);
                       HPEN hOldPen=3D(HPEN)SelectObject(hDC,hPen);
                       CLine* pLine=3Dnew =
CLine(ptPrevPos,MAKEPOINTS(lParam),iCurWidth,crCurColor); /*create new =
line object*/
                       pLine->DrawLine(hDC);
                       ptPrevPos=3DMAKEPOINTS(lParam);
                       SelectObject(hDC,hOldPen);
                       DeleteDC(hDC);
                   }
                }
                break;
                case 1: /* nothing here yet*/

Antw: Re: [Dev-C++] vUpdate can't find devcp.cfg

[Frank W. <F.W...@wi...>]

Hello Colin,

after downloading vUdate you metioned in your mail i be able to start
vUpdate but got the "devcpp.cfg" error within the vUpdate status
window.
After I got connected  with vUdate to look for new updates I was
informed that there is a more recent version of vUpdate.
It is not possible to update parts or files of Dev-C++ without updating
vUpdate first. So when I click on the update button a new version of
vUpadate will be installed and if I click on Look for Updates within
Dev-C++ I will get the error message described in my last mail without
opening vUpdate.

Greetings

Frank

>>> Colin Laplace <ha...@bl...> 10/23 2:00  >>>
Hello,

With Dev-C++ 4.9.6.0 the config file directory has changed for NT, 2000
and 
XP. You need to update your vUpdate to have it look for the correct
directory.
If you cannot autoupdate it, you can download it from :
http://www.zero47.com/devfiles/vUpdate.exe

[Dev-C++] Help file (dev.hlp) missing

[Haag A. <ach...@fa...>]

Hi,

after installing dev-c++ 4.9.6.0 I found the help file to be missing. On =
the mailing list, the answer to exactly the same question suggested to =
do a 'Check for updates' via the intenet. This would detect that the =
file 'dev.hlp' was missing and download it.=20

Alas, I do not have an internet connection on the machine where dev-c++ =
is installed. I have searched the whole of the bloodshed page as well a =
the last four month of the mailing list, but could not locate this file. =
Thus my question:

Where can I (manually) download the help file for dev-c++ 4.9.6.0.

Thanks a lot for your help,
Achim

[Dev-C++] One more whack at this question....

[David S. W. <xi...@pr...>]

I am getting errors using the wxwindows module for Dev-C++

I run Windows XP (and Linux)...but am writing a C++ application 
specifically for windows.

The first error I am getting is that "string-insensitive" compare has 
not been defined
The second is an illegal toolkit in font.h

Does anyone know anything about running Dev-C++ on XP with the WxWindows 
package?  Heck..it might not have anything to do with the WxWindows 
package...

Has anyone gotten Dev-C++ working on Windows XP?

[Dev-C++] Setting Up Tools

[Charles <cha...@at...>]

I need some guidance in the implementation of Tools.  I got the idea of
invoking some source code beautifier utility such as Great Code or Artistic
Style as a Tool.  They both work fine from the command line but I'm having
some trouble getting them to work from within Dev-C++.

I think that I want to use an Available Macro to specify the file to be
worked on.  The Quick Help on Macros doesn't give me enough information to
go on.  Can anybody tell me when to find documentation on the Tools
Configuration?

I'm running Dev-C++ version 4.9.6.5 (and 4.01) under Windows 98SE and have a
devcpp.hlp file current as of yesterday.

[Dev-C++] Input one file output another.

[Mitchell, T. (DLM) <Tam...@dl...>]

Rephrase question.

I am trying read test from one file and output to another file and am not
sure how to complete correctly.

#include<fstream>
#include<iostream>
using namespace std;

void main(){
   ifstream fin;
   ofstream fout;
   fin.open("Eb.txt");
   /*if(fin==0){
	   cout << " input file xx.txt not found "<< endl;
   }*/
   fout.open("y.txt");
   int a[10],i;
   for(i=0;i<10;i++)
	   fin >> a[i];
   for(i=0;i<10;i++)
	   fout << a[i] << endl;

}


Can anyone offer any suggestions.
