Hello, I am doing this program for my dad, which stores medecines. Can any one help me make a GUI for this Dos program, let's just say I'm not into Windows right now, I'm trying to get a good knowledge out of only using Win32 Console Application.
Well, if any of you guys find a way how to make things more efficent, please let me know, I would really appreciate it.
So far this is what i've done.
Thankyou in ADVANCE!! :D
How about I give you code for a window and you work it out. It seems as if it would almost be easier to rewrite the whole thing than mess with that and change every single DOS bit. Well if you want some code snippets relating to Win32 then let me know because that's my area ;).
Well, I don't know, are you talking about MFC?
Bleh, don't even say that. I despise MFC, I'm Win32 API all the way.
Ok...then...yet be easy on me...only 14...don't have a complex mind as others...
thankyou
Well don't worry I'm only 16. Ok Ok, here's the basic stripped down code for a window:
All that code will compile with only ONE header included "#include <windows.h>" but I saw that you included that in your code. All that code does is create a fixed window in the center of your screen, or at least the center of most screens. Try cutting and pasting your code into this and reforming it into something that will work with this. You will need to create child windows to display and receive user input from.Code:LRESULT CALLBACK WndProc(HWND,UINT,WPARAM,LPARAM);
int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,
PSTR szCmdLine,int iCmdShow)
{
HWND hwnd;
MSG msg;
WNDCLASS wc;
wc.style=CS_HREDRAW|CS_VREDRAW;
wc.cbWndExtra=0;
wc.cbClsExtra=0;
wc.hInstance=hInstance;
wc.lpfnWndProc=WndProc;
wc.hIcon=LoadIcon(NULL,IDI_APPLICATION);
wc.hCursor=LoadCursor(NULL,IDC_ARROW);
wc.hbrBackground=(HBRUSH)(COLOR_WINDOW+1);
wc.lpszMenuName=NULL;
wc.lpszClassName="Window";
if(!RegisterClass(&wc))
return 0;
hwnd=CreateWindow("Window","Window",WS_POPUPWINDOW|WS_CAPTION|WS_MINIMIZEBOX,(GetSystemMetrics(SM_CXSCREEN)/2)-320,(GetSystemMetrics(SM_CYSCREEN)/2)-240,640,480,NULL,NULL,hInstance,NULL);
ShowWindow(hwnd,iCmdShow);
UpdateWindow(hwnd);
while(GetMessage(&msg,NULL,0,0))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
return msg.wParam;
}
LRESULT CALLBACK WndProc(HWND hwnd,UINT msg,WPARAM wParam,LPARAM lParam)
{
switch(msg)
{
case WM_DESTROY:
PostQuitMessage(0);
return 0;
}
return DefWindowProc(hwnd,msg,wParam,lParam);
}
Um....I already know the basics of "Windows API" the only reason I didn't my program in this, is because I don't know how to get input from the User, only by buttons, but that doesn't help when you need letters for the medecine names
Oooh well that helps narrow it down. Well for that you will need to create an edit child window. As is done here(revised main function):
Then the NULL paramter after hwnd in the CreateWindow for hEdit is where you would make an ID for it so you can access the messages received and get the data from the Message Loop.Code:int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,
PSTR szCmdLine,int iCmdShow)
{
HWND hwnd,hEdit;
MSG msg;
WNDCLASS wc;
wc.style=CS_HREDRAW|CS_VREDRAW;
wc.cbWndExtra=0;
wc.cbClsExtra=0;
wc.hInstance=hInstance;
wc.lpfnWndProc=WndProc;
wc.hIcon=LoadIcon(NULL,IDI_APPLICATION);
wc.hCursor=LoadCursor(NULL,IDC_ARROW);
wc.hbrBackground=(HBRUSH)(COLOR_WINDOW+1);
wc.lpszMenuName=NULL;
wc.lpszClassName="Window";
if(!RegisterClass(&wc))
return 0;
hwnd=CreateWindow("Window","Window",WS_POPUPWINDOW|WS_CAPTION|WS_MINIMIZEBOX,(GetSystemMetrics(SM_CXSCREEN)/2)-320,(GetSystemMetrics(SM_CYSCREEN)/2)-240,640,480,NULL,NULL,hInstance,NULL);
hEdit=CreateWindow("EDIT","",WS_CHILD|WS_BORDER|WS_VISIBLE,5,375,625,40,hwnd,NULL,hInstance,NULL);
ShowWindow(hwnd,iCmdShow);
UpdateWindow(hwnd);
while(GetMessage(&msg,NULL,0,0))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
return msg.wParam;
}
EDIT:
Urgh, I gotta do my homework so I might be back on later tonight to help some more. Good luck mate!
strange, your title claims you're a C++ programmer and yet you eschew a relatively clean OO interface for one of the ugliest C interfaces known to man or machine. care to explain?Quote:

Well as far off topic as that was, were you trying to doubt me due to some deep fault or shortcoming of your own or just for the fun of it? Do you really think that in THIS thread that comment was necessary? Hmm, if you really had a concern couldn't you have just PMmed me so we don't branch-off on this poor kid's topic? As for why I don't like MFC, it is because it's a strew of classes and it's just one giant mess. It isn't as readable as raw Win32 and not as neat. Are you some MFC freak and want to start an argument or something? Well if so, NOT ON THIS THREAD.
Good. Now use wxWidgets. No need to rewrite your app if your dad wants to switch to *nix!Quote:
Bleh, don't even say that. I despise MFC, I'm Win32 API all the way.
If I PM'd you that wouldn't really help the OP, would it? I'm not an "MFC freak" (although I have used it professionally for several years), but I DESPISE win32 with a passion, and I don't like to see it advocated to beginners.Quote:

Well...do you guys can help me on my code...please...I wanna help my dad...
Here's your Dad's meds GUI database. You'll have to get an icon for IDI_ICON1. Also, you'll have to finish the EDIT option.Quote:

It doesn't actually update the Listview. So, you'll have to figure that one out. Please test thoroughly before your Dad uses it.
