So basically I am new to API programming and teaching myself. I've done a bit of console C++ that I got off of.... an internet tutorial. The story is the same here too. I am somewhat aware of what the lines of code do, though I am not yet a dictionary so please if anyone wishes to help, keep that in mind.
Onward to the problem --> I am trying to make a dialog box show up when I click on one of my menu options.
Curently the menu option I chose is "Blurp"-->"Go"
When I compile and run the program, I get my window and menu but upon selecting "Go", I get the "Oh God..." window saying "Dialog failed!" so I guess it's not creating the window...
I have checked my dialog box code (made in Resource Builder) against (in) another program that runs the dialog box out of a .rc file and it worked.
#include <windows.h>
#include "resource.h"
HWND hwnd;
HINSTANCE hInstance;
const char g_szClassName[] = "myWindowClass";
BOOL CALLBACK AboutDlgProc(HWND hwnd, UINT Message, WPARAM wParam, LPARAM lParam);
LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam);
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
LPSTR lpCmdLine, int nCmdShow)
{
WNDCLASSEX wc;
HWND hwnd;
MSG Msg;
wc.cbSize = sizeof(WNDCLASSEX);
wc.style = 0;
wc.lpfnWndProc = WndProc;
wc.cbClsExtra = 0;
wc.cbWndExtra = 0;
wc.hInstance = hInstance;
wc.hIcon = LoadIcon(GetModuleHandle(NULL), MAKEINTRESOURCE(IDI_MYICON));
wc.hCursor = LoadCursor(NULL, IDC_ARROW);
wc.hbrBackground = (HBRUSH)(COLOR_WINDOW+1);
wc.lpszMenuName = MAKEINTRESOURCE(IDR_MYMENU);
wc.lpszClassName = g_szClassName;
wc.hIconSm = (HICON)LoadImage(GetModuleHandle(NULL), MAKEINTRESOURCE(IDI_MYICON), IMAGE_ICON, 16, 16, 0);
if(!RegisterClassEx(&wc))
{
MessageBox(NULL, "Window Registration Failed!", "Error!",
MB_ICONEXCLAMATION | MB_OK);
return 0;
}
hwnd = CreateWindowEx(
WS_EX_CLIENTEDGE,
g_szClassName,
"The title of my window",
WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT, CW_USEDEFAULT, 240, 120,
NULL, NULL, hInstance, NULL);
if(hwnd == NULL)
{
MessageBox(NULL, "Window Creation Failed!", "Error!",
MB_ICONEXCLAMATION | MB_OK);
return 0;
}
ShowWindow(hwnd, nCmdShow);
UpdateWindow(hwnd);
while(GetMessage(&Msg, NULL, 0, 0) > 0)
{
TranslateMessage(&Msg);
DispatchMessage(&Msg);
}
return Msg.wParam;
}
BOOL CALLBACK AboutDlgProc(HWND hwnd, UINT Message, WPARAM wParam, LPARAM lParam)
{
switch(Message)
{
case WM_INITDIALOG:
return TRUE;
case WM_COMMAND:
switch(LOWORD(wParam))
{
case IDOK:
EndDialog(hwnd, IDOK);
break;
case IDCANCEL:
EndDialog(hwnd, IDCANCEL);
break;
}
break;
default:
return FALSE;
}
return TRUE;
}
LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
switch(msg)
{
case WM_COMMAND:
switch(LOWORD(wParam))
{
case ID_FILE_EXIT:
DestroyWindow(hwnd);
break;
case ID_BLURP_GO:
{
int ret = DialogBox(GetModuleHandle(NULL), MAKEINTRESOURCE(IDD_ABOUT), hwnd, AboutDlgProc);
if(ret == IDC_BUTTON0)
{
MessageBox(hwnd, "OK... OK?", "Notice", MB_OK | MB_ICONINFORMATION);
}
else if(ret == IDC_BUTTON1)
{
MessageBox(hwnd, "CANCELLED!", "Notice", MB_OK | MB_ICONINFORMATION);
}
else if(ret == -1)
{
MessageBox(hwnd, "Dialog failed!", "Oh God...", MB_OK | MB_ICONINFORMATION);
}
}
break;
// Other menu commands...
}
break;
case WM_LBUTTONDOWN:
{
char szFileName[MAX_PATH];
HINSTANCE hInstance = GetModuleHandle(NULL);
GetModuleFileName(hInstance, szFileName, MAX_PATH);
MessageBox(hwnd, szFileName, "This program is:", MB_OK | MB_ICONINFORMATION);
}
break;
case WM_CLOSE:
DestroyWindow(hwnd);
break;
case WM_DESTROY:
PostQuitMessage(0);
break;
default:
return DefWindowProc(hwnd, msg, wParam, lParam);
}
return 0;
}
Here is my .h file (There may be some extraneous definitions but I figure they can be weeded out later if they are there)
#define IDR_MYMENU 101
#define IDI_MYICON 201
#define ID_FILE_EXIT 9001
#define ID_BLURP_GO 9002
#define ID_HELP_ABOUT 9003
#define IDD_ABOUT 9004
#define DIALOG_0 9006
#define IDC_BUTTON0 0
#define IDC_BUTTON1 1
#define IDC_STATIC -1
#define IDC_TRACKBAR2 2
Here is my Menu - menu_one.ico is something I just had to pick and place myself... but it works for me.
#include "resource.h"
#include "windows.h"
IDR_MYMENU MENU
BEGIN
POPUP "&Blamo"
BEGIN
MENUITEM "W&indow Smash!", ID_FILE_EXIT
END
POPUP "&Blurp"
BEGIN
MENUITEM "&Go", ID_BLURP_GO
MENUITEM "O&ut of Bounds", 0, GRAYED
END
END
IDI_MYICON ICON "menu_one.ico"
And even though it seems to be fine, here is the dialog code (has extraneous features just for fun):
#include "windows.h"
#include "resource.h"
IDD_ABOUT DIALOG MOVEABLE PURE LOADONCALL DISCARDABLE 0, 0, 250, 100
STYLE DS_FIXEDSYS |DS_SETFONT |WS_POPUP |WS_VISIBLE |WS_SYSMENU |WS_THICKFRAME |WS_MAXIMIZEBOX |WS_MINIMIZEBOX |WS_CAPTION
CAPTION "Yoyo This Is It"
FONT 8, "Ms Shell Dlg"
LANGUAGE LANG_NEUTRAL, 0
BEGIN
CONTROL "Go",IDC_BUTTON0,"BUTTON",BS_DEFPUSHBUTTON |BS_VCENTER |BS_CENTER |WS_CHILD |WS_TABSTOP |WS_VISIBLE ,29,60,63,20
CONTROL "Dude!",1,"BUTTON",BS_DEFPUSHBUTTON |BS_VCENTER |BS_CENTER |WS_CHILD |WS_TABSTOP |WS_VISIBLE ,157,60,63,20
CONTROL "",2,"msctls_trackbar32",WS_CHILD |WS_VISIBLE |0x18,10,20,230,20
CONTROL "Woah Slide Bar",IDC_STATIC,"STATIC",SS_LEFT |WS_CHILD |WS_GROUP |WS_VISIBLE ,15,9,51,8
END
So yeah, the code feels a bit patchwork to me when I think about it, but it runs just fine aside from this dialog box problem.
In short, I am just needing help getting the dialog box to ... appear when I click "Blurp"-->"Go". However I would be totally thrilled to hear (read) suggestions or input of any kind in adittion to that.
