hi again, first of all thanks to all of you for your comments. some data : board is asrock-k8upgrade-nf3 (since asrock states that this model is NOT sold world wide, I don't know if you are familiar with it. there's no on-board graphics, so the only part attached right now is the gforce graphics...

I selected 'normal start' and it shut down. tried again, same thing. replaced the hdd, tried to install winxp, first step it does, then install process restarts pc, I see winxp logo for half...

hi, hope there's somebody around in the world of web-programming who remembers old BASIC and MASM. here is what i got : compiled BASIC-program start.exe compiled BASIC program prog1.exe three libraries of asm-modules asm.lib, prog.lib and start.lib, where asm is the base-library. prog needs...

instead of the directory structure you can can use structures (or classes) and store the data in ONE file. for that you'll have to study access to binary file. or try serialization with class-data

if you store at position x, your array can only handle 1440-x bytes.

try this : sWork[MAXLENGTH] = '\r'; sWork[MAXLENGTH+1] = '\n'; for (i=0; i<MAXLINES; i++) { for (j=0; j < MAXLENGTH; j++) sWork[j] = psL.psLine[i][j]; PrinterSendDataString (sWork); }

build sWork using a loop and look what happens and you know that inserting '\0' will overwrite data.

thank you guys, I tried it, it works !

hi, void f(MyStruct* p) { p = new MyStruct; } is called like this : f(ptr1); with ptr1 declared as MyStruct* ptr1; I think passing the pointer as above is incorrect 'cause p has a correct value but ptr1 is 0 after the function call. so what's wrong ? thanks in advance

what's the backslash for ? makes sense that way [\[\]] and will compile

it works !!!

hi, great site but no solution to my problem I will describe it differntly: func1(char*, int(*)()) is hidden somewhere in an old c-library the 2nd argument of func1 is a pointer to func2(char**, char**) both functions are declared in the c++-app using 'extern C' I must, however, declare func1...

Hi good morning (well, at least here in germany it's morning) now it's more than a day I've been trying to solve the following problem : from c++-application I call extern function func1 func1 has as argument pointer to func2. i cannot modify func1 and func2 however I'm unable to set the...
