Hey, its me agian. First off i would just like to say thanks to all those of you who helped me in my former posts(everyone was incredibly nice and helpfull), and er keep it coming boys with your help im'a gonna learn me to program and make me one of those there MMORPGs ive heard so much about (just kidding
.
Anyway, so ive been trying to make a command line box thingy (a box into which one can enter text and then hit enter, and then something happens,) and after three or four false starts i believe i have finally hit a snag which no amount of googleing can solve.
Heres the back story: I started out by "M$ paint"ing nine little squares that each had a part of the border for my edit box, and then loading them and turning them into spites and then making a new bitmap and then writing Sephnroth's text to that, and then making that into a sprite and then displaying the whole thing like one big happy family. I dont remember how i captured the input (as this was a few days ago,) but it had problems and in general the whole thing was crap, so i scrapped it.
After that i moped for a bit, until, as if by devine providance i chanced across Sephnroth's Menu's and Dialogs - DarkSDK Tutorial, (Sephnroth you Rock, by the way) which opened up a whole new world for me. Really. It did. And i have been simply head-over-heels about the Windows API ever since. Not really, but i do need to get this thing to work so here is the down and dirty.
An edit box is perfect for my needs, but i cant figure out how to know when the enter key is pressed. I figured it was something like:
case: WM_CHAR
case: WTF_THE_ENTER_KEY
in my dialog's procedure thingy, but i aparently have done something incorectly because it dont work. Any help would be greatly appreciated. Thanks.
I created a new DGSDK project in VS 2003 which i named Main.
Here is Main.cpp
// Main.cpp : The main entrypoint for the application.

#include "DarkSDK.h"

BOOL CALLBACK CommandProc(HWND hwndDlg, UINT message, WPARAM wParam, LPARAM lParam);
void PaintScreen();

bool Exit = false;
bool textInput = true;
bool textWindow = false;
char cmdString[256];
HWND textBox = NULL;
void DarkSDK (void)
{
dbSyncOn();
dbSyncRate(0);
sprintf(cmdString,"This should display the text in the above box after hitting enter");
lpPrevWndProc = (WNDPROC) SetWindowLong(g_pGlob->hWnd, GWL_WNDPROC, (LONG)MainWndProc);
textBox = CreateDialog(GetModuleHandle(NULL), MAKEINTRESOURCE(IDD_CMDDLG),
g_pGlob->hWnd, CommandProc);
if(textBox != NULL)
{
ShowWindow(textBox, SW_SHOW);
}
else
{
MessageBox(g_pGlob->hWnd, "CreateDialog returned NULL", "Warning!",
MB_OK | MB_ICONINFORMATION);
}
// loop until the escape key is pressed
while (LoopSDK())
{
if (dbEscapeKey())
{
break;
}
dbText(40, 40, cmdString);
dbSync();
}
}
//========================
// Window message handler

LRESULT APIENTRY MainWndProc(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam) {
switch (uMsg) {
case WM_PAINT:
//PaintScreen();
break;
default:
break;
}
return CallWindowProc(lpPrevWndProc, hwnd, uMsg, wParam, lParam);
}
BOOL CALLBACK CommandProc(HWND hwndDlg, UINT message, WPARAM wParam, LPARAM lParam) {
int len;
switch (message) {
case WM_CHAR:
switch (wParam)
{
case 0x0D:// Process a carriage return.!!!!!!!!!!!!!!!!!
len = GetWindowTextLength(GetDlgItem(textBox, IDC_CMDEDIT));
if(len <255) {
GetDlgItemText(textBox, IDC_CMDEDIT, cmdString, len + 1);
SetDlgItemText(textBox, IDC_CMDEDIT,"");
}
//return true;
break;

break;
}
case WM_COMMAND:
switch (LOWORD(wParam)) {
case WM_CLOSE:
DestroyWindow(textBox);
break;
case WM_DESTROY:

break;
}
}
return false;

Some days the cascading moments which constitute my experience dissolve to reveal a sense of clarity which transcends reasoning.
And then there are days like today.
