[Noorez K. <lor...@ho...>]

Is there a way to prevent an HWND window from being resized?

[Dev-C++] Again Resource Editor

[Benjamin S. <B.S...@ar...>]

Hi, i tried searching for it in the mailing, and there were many results 
but i couldnt
find clear answer for my question.

In the help file fer dev-cpp 4.9.9.2  a Resource Editor is 
mentioned(Step 6 i think)
but i am unable to find it.

Is it a bug at my side or isnt it there yet(or ever).

[Dev-C++] Packing wxWidgets application with libraries

[Francis B. <fb...@fr...>]

Hi,

How can I create a bundle my wxWidget application developped with Dev-C++ and wxWidgets Devpak, to install it on a Windows box?
I'm a Windows newbie ;) and I don't know how to start my software out of Dev-C++ context and install my software on an other computer.

Thanks

Francis

 

[Dev-C++] Possible bug? (fdopen and fgets)

[Tracid <tr...@za...>]

Hello.

I've got a little problem. If I use the fdopen function, and then I use 
fgets, the compiled program crashes*.
Example:

#include <stdio.h>
#include <winsock.h>
#include <windows.h>

#pragma comment (lib, "ws2_32")

int main(int argc, char *argv[])
{
    WSADATA wsaData;
    if (WSAStartup (MAKEWORD(1, 1), &wsaData) != 0) {
       printf ("[-] WSAStartup failed.\n");
       return (1);
    }

    int sockfd; 
    char buf[1024];
    FILE *in;

/* some stuff here, connection to server is successfull */

    in = fdopen (sockfd, "r"); /* in
    while (fgets(buf, sizeof(buf), in) != NULL) { /* and here the 
compiled program crashes* */

/* some other stuff */
------------------

Using cygwin, it works well.
*Crashes = Windows error reporting window appears, and program ends 
suddenly.

Is this problem caused by Dev-Cpp or the Windows sockets?

Thank you.

PS: I admit that I am quite a newbie at C programming, but I've tried a 
lot of different variations for this, but it still crashes....

Re: [Dev-C++] Scrollbars

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

No, I don't have the time to read through the code to look for errors -
it's about 2 am local time...

However, don't you think that you should describe your problem a little
bit more than: "There is a bug while trying to resize though."

When asking for help: Always describe what happens and what you expected
to happen.

[Dev-C++] Scrollbars

[Jason B. <red...@ya...>]

Here is my best attempt at scrolling a bitmap.  There
is a bug while trying to resize though.  Since a put
this together from missing parts in about half an
hour, that would make sense.  Any ideas?


//-------------------------------------------------------------

#include <stdio.h>
#include <string.h>
#include <windows.h>

/*  Declare Windows procedure  */
LRESULT CALLBACK WindowProcedure (HWND, UINT, WPARAM,
LPARAM);

/*  Make the class name into a global variable  */
char szClassName[ ] = "WindowsApp";

int w,h;
HBITMAP bitmap;
BITMAP bm;
HDC hdc;
HDC hdcmem;
HINSTANCE hinst;
PAINTSTRUCT ps;
SCROLLINFO si;

/* These variables are required by BitBlt.            
         */

         */

[Dev-C++] WSAAsyncSelect

[Noorez K. <lor...@ho...>]

I dont know if i'm really understand the WSAAsyncSelect function after 
reading the MSDN.

Ok...So lets say i receive a connection on a SOCKET. Could i then call the 
WSAAsyncSelect on the socket with FD_READ to know when i have to call the 
recv() to get the data from that SOCKET?

And if I then wanted to echo the data back, would I have to call 
WSAAsyncSelect on the SOCKET  with FD_WRITE before I call the send() 
function?

[Dev-C++] How to convert numbers in string format to a vector

[Rodrigo C. <rc...@gm...>]

Hi C++ gurus: hope you have a nice Xmas!

I want to convert a string that cointains numbers separated by spaces (or
other characters) to a vector or array containing the numbers, like:

"0 1 0 3 4 0 5 0"   =3D> [0 1 0 3 4 0 5 0]

or

"0,1,2,4,6,7" =3D> [0 1 2 4 6 7]

The number of colums (number of numbers) of each string is unknown. How can
I do this using C++ strings?

Thanks.

down for a program that i'm making. I can't find a tutorial on this. Does 
anyone know of any?

I'm afraid Dev-C++ will not allow you to do that. I had been looking for 
something like that myself, until I found the freeware program "Source 
Monitor", which does not only count lines, but also provide other 
metrics (which can be very useful for monitoring a larger project).

You can get it at http://www.campwoodsw.com/sm20.html

I know, this is not what you asked for originally, but it may be helpful 
anyway ;)

Yours,
  David.

[Dev-C++] total number of lines in project

[Murat A. <mur...@ya...>]

I like to see how many lines of code I wrote, but
the project properties shows them per file. Is
there a way to count the total number of lines in
the whole project?
