You are correct but, There are 47 names, units, min, max. At each (ith) position the data is related. If I just run through the loop 10 times then I won't get the rest of the data all put in the correct array within the struct. I have it working with a 2 dimensional array. I have limited memory so I need to really be sparing on memory. So, I really need to store the names and units in a single dimension array I hope all of that made sense. I have a feeling that it won't work. thanks, Steven

Like I said, untested code, and I'm a little rusty on C++ templates, but I figured it was essentially ok, and certainly illustrated what I wanted to suggest. -- Ian Darling If I was any more loopy, I'd be infinite.

It's saying that the type of void is unknown or zero. thanks steven

strcmp() returns 0 if the strings are the same, non-zero if they are different. Your if statements will always be executed if the strings are not the same, which I assume is the majority of times. It looks like you want the if statements to be executed if the strings are equal, so you'll need to modify them like this: if(strcmp(temp, "pla") == 0) etc...

Yes, I have a PCI card with a gig of memory that is shared with 5 other machines. Some of the words are longer than others so, if I just make the 2nd dimension the size of the longest word will I have any problems reading them on the other side of the network? thanks, Steven

TSimHeader header; strcpy(header.Name, name.c_str()); Should do the trick. If you're sending an array of TSimHeader's then you'll have something like this: TSimHeader headers[10]; strcpy(header[0].Name, name.c_str()); Similarly for other members of the array.

Prototype: char *_strdup( const char *strSource ); Bad: (char)strdup(name.c_str()); // this is incorrect usage Good: strdup(name.c_str()); // normal usage Ok: (char*)strdup(name.c_str()); // this is redundant INTP

OK I see what you are saying, Thanks, steven

The size of a double is 8 bytes. Use the sizeof(double) to see that your self. I have no clue why you would want to do this. Also if you don't pack the data using #pragma pack(push,1) before your struct and #pragma pack(pop) after your struct you will get unexpected results. John

a char is a single byte so the highest value if cast as an integer would be 255 unsigned or 127 signed. It sounds like you are actually asking about the max length of a char array. This would be determined either statically by the defining your array like: // pick a number that is longer than your longest word #define MAX_WORD_LENGTH 20 // if you know how many words you will conceivably have #define MAX_WORDS 100 char words[MAX_WORD_LENGTH][MAX_WORDS]; If this definition is made locally - you'll be limited by the size of your stack. If made globally, you'll be limited by your data segment size - or something like that :) If you don't know how many words you will have or how long they could possibly be then you'll need to pre parse the file and determine how many words there are and how long the longest one is. Then you could use char* buffer; buffer = (char* )malloc(NUM_WORDS*LONGEST_WORD); I'm going to live forever or die trying!

I am not completely sure what you asking. what I meant is : class A { public: typedef struct B{...}B; const B* getMyDatamember() const {return &b;} private: B b; };

then I need to see full cpp file compilation of which gives an error

That aside, once you have the members of this variable set accordingly, you need to do individual assignments to TSimHeader_arr[0], like: TSimHeader_arr[0].Min = TSimHeaderVar.Min; TSimHeader_arr[0].Max = TSimHeaderVar.Max; TSimHeader_arr[0].SignalCount = TSimHeaderVar.SignalCount; etc.

Unless you are using data_ptr during the parsing of the file, don't initialize it until afterwards.

Figured it out, I just made a pointer to the structure and accessed the data using the pointer sj
