Need GUI Input box and button to execute :)

P: n/a
Hey guys,
I've just started in a programming company, and meet some difficulties,
as I start from scratch.....

I have a command line program I've wrote, and want to transfer it to
GUI.

It does this: reads user input with cin >>, and then inputs it in a
variable, when you press enter, it starts executing code, based on your
input.

What is the easyest way to transfer the program to GUI?

I have a program Dev C++ that is opensource, but it does not allow to
edit the program in GUI.

here is the source I have automatically generated by the Dev C++
program:

#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 WINAPI WinMain (HINSTANCE hThisInstance,
HINSTANCE hPrevInstance,
LPSTR lpszArgument,
int nFunsterStil)

{
HWND hwnd; /* This is the handle for our window */
MSG messages; /* Here messages to the application are
saved */
WNDCLASSEX wincl; /* Data structure for the windowclass */

/* The Window structure */
wincl.hInstance = hThisInstance;
wincl.lpszClassName = szClassName;
wincl.lpfnWndProc = WindowProcedure; /* This function is
called by windows */
wincl.style = CS_DBLCLKS; /* Catch double-clicks */
wincl.cbSize = sizeof (WNDCLASSEX);

/* Use default icon and mouse-pointer */
wincl.hIcon = LoadIcon (NULL, IDI_APPLICATION);
wincl.hIconSm = LoadIcon (NULL, IDI_APPLICATION);
wincl.hCursor = LoadCursor (NULL, IDC_ARROW);
wincl.lpszMenuName = NULL; /* No menu */
wincl.cbClsExtra = 0; /* No extra bytes after
the window class */
wincl.cbWndExtra = 0; /* structure or the
window instance */
/* Use Windows's default color as the background of the window */
wincl.hbrBackground = (HBRUSH) COLOR_BACKGROUND;

/* Register the window class, and if it fails quit the program */
if (!RegisterClassEx (&wincl))
return 0;

/* The class is registered, let's create the program*/
hwnd = CreateWindowEx (
0, /* Extended possibilites for variation
*/
szClassName, /* Classname */
"RemoteClick", /* Title Text */
WS_OVERLAPPEDWINDOW, /* default window */
CW_USEDEFAULT, /* Windows decides the position */
CW_USEDEFAULT, /* where the window ends up on the
screen */
400, /* The programs width */
200, /* and height in pixels */
HWND_DESKTOP, /* The window is a child-window to
desktop */
NULL, /* No menu */
hThisInstance, /* Program Instance handler */
NULL /* No Window Creation data */
);

/* Make the window visible on the screen */
ShowWindow (hwnd, nFunsterStil);

/* Run the message loop. It will run until GetMessage() returns 0
*/
while (GetMessage (&messages, NULL, 0, 0))
{
/* Translate virtual-key messages into character messages */
TranslateMessage(&messages);
/* Send message to WindowProcedure */
DispatchMessage(&messages);
}

/* The program return-value is 0 - The value that PostQuitMessage()
gave */
return messages.wParam;
}
/* This function is called by the Windows function DispatchMessage()
*/

LRESULT CALLBACK WindowProcedure (HWND hwnd, UINT message, WPARAM
wParam, LPARAM lParam)
{
switch (message) /* handle the messages */
{
case WM_DESTROY:
PostQuitMessage (0); /* send a WM_QUIT to the message
queue */
break;
default: /* for messages that we don't
deal with */
return DefWindowProc (hwnd, message, wParam, lParam);
}

return 0;
}

Use an HTML or script front-end that runs your program.

Otherwise, use a C++ GUI library.

The details of that are system-specific and off-topic in this group.

Is there a cross-platform way to do this? Just wondering...

I think that depends on whether one's willing to have the user install
something much, much larger than the original little C++ program...

So, the answer basically is "no". I can't do some:

<form target="myprogram.exe">
<submit>Run it on Windows</submit>
</form>

Well, that's what you /can/ do. For some platforms you can do a
platform specific HTML thing that runs the program (in Windows that
would be an [.hta] file). And you can put the program on a server and
invoke it via e.g. CGI; I guess that includes using a local web server.

What I meant was that there's a certain rather large overhead, compared
to a really tiny C++ program, if it is to be platform-independent.

Then perhaps better to just use a portable C++ GUI library...
