Thread: Weird things happening!!!!!!

This is a bit difficult to explain, but here goes anyway

I have a workspace with 2 .c files, 3 .h files and a .rc file

every now and again i get errors about 2 functions that have always worked and i have not altered them in any way whatsoever either directly or indirectly

because i cant track down the cause of these errors i remove the debug folder and rebuild the project. No errors, i make a small change to a file, 26 errors, i remove the change, 26 errors are still there ?????

i am slowly loosing my sanity, can someone have a look at my code and aid me in fixing this weird happening please

the functions in question are doFileSave & doFileOpen in the test1.c

i have already reinstalled visual studio 6 in case it was a bug in the program, but still the same, i am running winXP

thanx in advance

Code:

BOOL LoadTextFileToEdit(hEdit, pszFileName);
BOOL SaveTextFileFromEdit(hEdit, pszFileName);
//void DoFileOpen(hwnd);
//void DoFileSave(hwnd);

void splash(hInstance);

HWND CreateNewMDIStatus(hMDIClient);
LRESULT CALLBACK WndProc(hwnd, msg, wParam, lParam);
LRESULT CALLBACK MDIStatusWndProc(hwnd, msg, wParam, lParam);
BOOL SetUpMDIStatusWindowClass(hInstance);
BOOL CALLBACK SplashDlgProc(hwnd, message, wParam, lParam);
BOOL CALLBACK AboutDlgProc(hwnd, message, wParam, lParam);
BOOL CALLBACK MenuDlgProc(hwnd, message, wParam, lParam);
BOOL CALLBACK ToolDlgProc(hwnd, Message, wParam, lParam);
BOOL CALLBACK WeightDlgProc(hwnd, message, wParam, lParam);
BOOL CALLBACK SearchDlgProc(hwnd, message, wParam, lParam);
BOOL CALLBACK EditDlgProc(hwnd, message, wParam, lParam);
float convertTextToNum(char *text);
void displayMenu(hwnd);
void displayUserScreen(hwnd);
void clearUserFields(hwnd);
void displayUserControl(hwnd);

See anything wrong here? Your prototypes are correct elsewhere so I assume this is a tiredness induced problem and I won't go into details. I didn't think this was valid either(but I may be wrong on this one):

Code:

static void logger(char path[MAXSTR], char test[MAXSTR]);

Fix your prototyes in test.c and header files and see if the errors remain.

Does anyome know why the compiler doesn't baulk on these invalid "prototypes"? The errors suggest that the compiler interprets them as being functions whose argument lists are not specified or take no arguments.

many thanx, i dunno how i missed all them function prototypes, i must have looked at them loads of times

but as i recall when i started this code, when i put the variable type and name i got errors which is why i changed them to just the name

anyhow many thanx again

damn it, now all of a sudden one of the functions that worked before aint working too good, sometimes it works sometimes it crashes the system

in one instance i ran the program and all worked well, so i exited the program, removed a commented line and ran the program again, IT NEVER WORKED

i undid the removal of the uncommented line and then it worked

Question: How stable is Visual Studio 6?

the line number that is giving me problems is 989

can someone have a look and see if they can spot anything wrong with my code as i am completely confused by all this

thanx

Line 989 is:

Code:

int temp = popStack(0); //get value from top of stack

popstack calls removeStack():

Code:

static int removeStack(stk * stack){
		stk * ptr;   
		int temp;
		
		ptr = stack->next;   // Set temporary variable to the second item in the list
		temp = ptr->id;   // Retrieve the ID number of the removed item
		stack->next = ptr->next;   // Alter the list
	
		total ++;
		free (ptr);   // Remove the item from memory
		return temp;
}

The question I would ask is "what happens if stack->next is NULL?".

A good idea is to learn to use the debugger. Set a breakpoint on the line that is causing you trouble and follow the code through to where it is crashing.

>>Question: How stable is Visual Studio 6?<<

Believe me, I've sworn at the compiler numerous times when I've had an unexplainable error. However, it has usually turned out to be a problem in my code. No compiler is perfect but most seem to be pretty good.
