aight trying to use CreateProcess() for a remote control plugin and it's erroring up the ying yang now and it USED to work, the complied dll still works but just can't compile

here's the code

Code:

		case RMCTRL_0:
			STARTUPINFO si;
			PROCESS_INFORMATION pi;

			ZeroMemory( &si, sizeof(si) );
			si.cb = sizeof(si);
			ZeroMemory( &pi, sizeof(pi) );

			// Start the child process. 
			CreateProcess( NULL,  // No module name (use command line). 
				"\"C:\\Program Files\\Winamp\\Winamp.exe\"", // Command line. 
				NULL,             // Process handle not inheritable. 
				NULL,             // Thread handle not inheritable. 
				FALSE,            // Set handle inheritance to FALSE. 
				0,                // No creation flags. 
				NULL,             // Use parent's environment block. 
				NULL,             // Use parent's starting directory. 
				&si,              // Pointer to STARTUPINFO structure.
				&pi );             // Pointer to PROCESS_INFORMATION structure.

			return TRUE;

And here's the error msg:

Code:

I've been reading the MSDN pages and have taken code EXACTLY off their site and it errors.

I'm programming in VS6 on WinXP SP1

Thanks

gets you every time

yea i know, i hate stupid things like that!!

now if i can only learn how to read and write to a dialog box i'll be all set

freestyler,

for a simple read/write, try "GetDlgItemText" and "SetDlgItemText" ... Basically if you had a textbox called "IDC_TEXT1" and a string callad "lpszText" and the handle to the dialogbox was called "hWndDiag", it would look like this:

to get the text in the textbox:
GetDlgItemText(hWndDiag, IDC_TEXT1, lpszText, strlen(lpszText) );

to set the text in the textbox:
SetDlgItemText(hWndDiag, IDC_TEXT1, lpszText );

cheers,

GTC

What program are you using to write it in? I am learning C++ currently, and have been using the GCC/G++ 3.3 compilers and Pico as my editor. Nice and clean, and I can do it from anywhere

Make it easy on yourself and learn to use the vi editor. Saves a ton of time.

**SiGmA_X** · 08-01-2003, 01:11 PM

Yeah, vi is elite

But I don't want to waste the time learning it.. It's what we use at work so I should learn it tho, damnit!

yeah that's what i thought, must have an error elsewhere, silly windows programming

**freestyler** · 08-01-2003, 09:23 PM

ok here's what i have and it's not working:

Code:

#define BUFSIZE       80
#define ID_NUM_0	  1040
#define ID_NUM_1      1041
#define ID_NUM_2      1042
#define ID_NUM_3      1043
#define ID_NUM_4      1044
#define ID_NUM_5      1045
#define ID_NUM_6      1046
#define ID_NUM_7      1047
#define ID_NUM_8      1048
#define ID_NUM_9      1049

FILE *fp;
int gFocusBoxState,gStopWatch,gResize,gVolume,gVolInc,gVer;
char NUM_0[BUFSIZE],NUM_1[BUFSIZE],NUM_2[BUFSIZE],NUM_3[BUFSIZE],NUM_4[BUFSIZE],NUM_5[BUFSIZE],NUM_6[BUFSIZE],NUM_7[BUFSIZE],NUM_8[BUFSIZE],NUM_9[BUFSIZE];

......

	SetDlgItemText(hDlg, ID_NUM_1, NUM_1);
	SetDlgItemText(hDlg, ID_NUM_2, NUM_2);
	SetDlgItemText(hDlg, ID_NUM_3, NUM_3);
	SetDlgItemText(hDlg, ID_NUM_4, NUM_4);
	SetDlgItemText(hDlg, ID_NUM_5, NUM_5);
	SetDlgItemText(hDlg, ID_NUM_6, NUM_6);
	SetDlgItemText(hDlg, ID_NUM_7, NUM_7);
	SetDlgItemText(hDlg, ID_NUM_8, NUM_8);
	SetDlgItemText(hDlg, ID_NUM_9, NUM_9);
	SetDlgItemText(hDlg, ID_NUM_0, NUM_0);

.........

		GetDlgItemText(hDlg, ID_NUM_1, NUM_1, strlen(NUM_1));
		GetDlgItemText(hDlg, ID_NUM_2, NUM_2, strlen(NUM_2));
		GetDlgItemText(hDlg, ID_NUM_3, NUM_3, strlen(NUM_3));
		GetDlgItemText(hDlg, ID_NUM_4, NUM_4, strlen(NUM_4));
		GetDlgItemText(hDlg, ID_NUM_5, NUM_5, strlen(NUM_5));
		GetDlgItemText(hDlg, ID_NUM_6, NUM_6, strlen(NUM_6));
		GetDlgItemText(hDlg, ID_NUM_7, NUM_7, strlen(NUM_7));
		GetDlgItemText(hDlg, ID_NUM_8, NUM_8, strlen(NUM_8));
		GetDlgItemText(hDlg, ID_NUM_9, NUM_9, strlen(NUM_9));
		GetDlgItemText(hDlg, ID_NUM_0, NUM_0, strlen(NUM_0));

ID_NUM_X are "Edit" boxes on the dialog box, NUM_X are just my global vars

GetDlgItemText & SetDlgItemText both don't seem to be working, the ini file that gets created isn't having anything wrote to it which would come from the dialog box

TIA
