Now I'm getting runtime errors whenever I try to kill a process.

try
char szExe[260];
or
do what Wiccaan said to do, (initialize the charecter using the LB_GETTEXTLEN before)

Don't you need the correct permissions to kill a process?

PROCESS_TERMIANTE is all you need.
Got it working. But I'm a little confused. I made my PK function to take a char*, and not a char. But I declared szExe as a char and not a char* and it worked. Shouldn't I have got an error trying to convert a char to char*?

an array of char is treated like a char pointer
char * buf;
char buf2[33];
type function(char* buf){
do stuff
}
You could pass buf and buf2 in this because array char is a char pointer

Oh really? Never knew that (weird no tutorials mention that). Got a question. If I wanted to make a new (child) window when the user hits the about button. Would I do something like this?
| Code: |
... //skipping WM_COMMAND and case IDC_PK_BUTTON:
case IDC_ABOUT_BUTTON:
HWND Ahwnd = CreateWindowEx(0, szClassName, "About", WS_CHILD | WS_VISIBLE, CW_USEDEFAULT, CW_USEDEFAULT, 100, 100, hwnd, (HMENU)IDC_ABOUT_FORM, GetModuleHandle(NULL), NULL);
|
I'm not really sure because I've never made a child window before.

I, at least, use resource dialogs. So for my cPAD app the part of the dialog was like this
| Code: | IDD_ABOUT DIALOG DISCARDABLE 0, 0, 220, 60
STYLE DS_MODALFRAME | WS_POPUP | WS_CAPTION | WS_SYSMENU
CAPTION "My About Box"
FONT 8, "MS Sans Serif"
BEGIN
DEFPUSHBUTTON "&OK",IDOK,174,30,50,14
GROUPBOX "About this program...",IDC_STATIC,7,7,225,52
CTEXT "CPad written by Steve B.\n\n\nWritten in C++",
IDC_STATIC,16,18,144,33
END |
Then you make a button or some WM_COMMAND do this
| Code: | case IDM_WHAT_ABOUT:{
int ret;
ret = DialogBox(GetModuleHandle(NULL),
MAKEINTRESOURCE(IDD_ABOUT), hwnd, AboutDlgProc);
if(ret == IDOK){}
else if(ret == -1){
MessageBox(hwnd, "Dialog failed!", "Error",
MB_OK | MB_ICONINFORMATION);
}
}
break; |
Of course IDM_WHAT_ABOUT is my own resource...
Notice the last param of MAKEINTRESOURCE (AboutDlgProc). You have to make ANOTHER, yes another, wndproc. I'll paste mine.
| Code: | 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;
}
break;
default:
return FALSE;
}
return TRUE;
}
|
Notice that you return TRUE and FALSE. I forget the reasons but it deals with how windows processes child messages. If you return numbers it will never continue and hang, as far as i know.
When in Doubt:
http://www.winprog.org/tutorial/dialogs.html
Appalsap also mentioned creating a dialog template in memory and not resource, just throwing it out there.

Definitely. I plan on releasing it with the source.
@blankrider
Is there anyway to do it without using resources. Like at runtime (I really don't like resources). Oh and btw I get an unexpected end of file with resource.h. And is there a link to a tutorial on how to make child windows, like real windows, and not dialog boxes (for new projects I will work on).

Proc terminator example attached. Uses resource file to create the about dialog. Sorry if the codes sloppy I just tossed this together fairly quickly and I haven't slept in 2 days which is what I'm going to go do now... sleep time >.>

Ok...this didn't really help. So I'm just going to post my code...(btw I don't use resources a lot, so yeah...and I did it all manually)
resource.h (get an error on this, unexpected eof found)
| Code: |
#define IDD_ABOUT_POPUP 104
|
resource.rc
| Code: |
#include <resource.h>
IDD_ABOUT_POPUP DIALOG DISCARDABLE 0, 0, 220, 60
STYLE DS_MODALFRAME | WS_POPUP | WS_CAPTION | WS_SYSMENU
CAPTION "About Process Killer"
FONT 8, "MS Sans Serif"
BEGIN
DEFPUSHBUTTON "&OK",IDOK,174,30,50,14
GROUPBOX "Creator",IDC_STATIC,7,7,225,52
CTEXT "Process Killer written by oib111\n\n\nWritten in C++",
IDC_STATIC,16,18,144,33
END

Just put a new line, blank of course, at the end of both the files
The resource and header compiler is picky. So just put a newline and you'll be fine
