[QUOTE=atrusmre]If I have a MFC program that opens a socket connection, how would I test to see if the socket has succesfully opened or not?[/QUOTE] almost any function in the winsock api returns the value SOCKET_ERROR in the event of failure. you only have to check this for errors. if …

well, if the number of controls is small, using global variables is okay. but i prefer to create them locally inside the create function and then use GetDialogItem API to get the handles of the controls when i need them. this eliminates the need of global window handles and makes …

Since you have functions that determine [QUOTE]If the year is a leapyear how many days the month in the dates have[/QUOTE] the rest is easy. Your function to output the number out of the total days in an year should be something like this [code] int ReturnNumberOutOfTotalDays( Date date ) …

Wont go mad at characters. But you will have to guard against multiple characters …

Well perni's solution should work. But why cant you use a normal array like [code]char pBuf = char[1000025][/code]? It will cleanup itself as it goes out of scope. Saves you a lot of trouble.

Well what do you mean by running only once? I compiled and ran the program, and it ran okay. I added two patients, one doctor and printed the patient and doctor list, all by one go at the program. The other options didnt work as I think you have to …

I dont think it is a sorting function at all. All it does is ask the user for a name, searches the database for a match, and once a match is found display the information the user wants to see. Nope, no sort.

unichar can be more than 2 bytes? I thought it was always 2 bytes.

If you want to do the detail entering and the detail printing seperately, you should define a doctor array inside the main function, and pass that function name to the two functions you are using ( Enter_Doctor_Details(), and Print_Doctor_Details() ). Better if you look up for, global scope, local scope, …

Define the Constructors for junior and consultant. [CODE]junior::junior()[/CODE] and [CODE]consulant::consultant()[/CODE] , or remove the [CODE]junior(); [/CODE]and [CODE]consultant();[/CODE] lines in the class declarations.

use the [URL=http://www.cplusplus.com/ref/cstring/memset.html]memset[/URL] function.

Dont use same variable names. It makes it confusing to you and creates bugs that are very hard to find.

I personally believe that following the Petzold Book ( I believe that is the book number one in your list ), is the best when starting GUI programming in Windows. So before starting on MFC you better go through that. Initially the Applications will look ugly, due to the use …

Shouldnt [code]for (index = 9; index<0; index--)[/code] be [code]for (index = 9; index[COLOR=Red]>=[/COLOR]0; index--)[/code]. And since you are passing the size of the array use that instead of the hard coding 9. Like this[code]for (index = size; index>=0; index--)[/code]

No, your question is not stupid. If is one that occurs to all beginners in socket programming. Actually all 3 of your options are possible. So I will give you the answer for the first question which is I think the easiest and good to get some exposure to thread …

Yes it is possible. But the problem is you are not saving it to a variable in the main function. The variable [CODE]option [/CODE]is declared inside the display_function so the main function does not know about it. Change your code as below and it will work. [code] #include "display.h" int …

and give us the compile errors.

Lets say you have a global variable and a local variable with the same name. When you compile it, the compiler will use the local variable, and not the global variable. If you prefix the variable name with ::[variablename], then the compile uses the global variable. [code] #include <iostream> using …

search for the malloc, calloc, realloc functions.

The declaration `void getdata(ifstream fin);` and its definition int getdata(ifstream fin, ofstream fout) { ... } does not match. You will get a link error. Also I think I see a mismatch in the {} braces. This also should give you an EOF not found error. Use properly indented code, …

could it be that infile and outfile are not defined? It would help if you posted the compile errors. [CODE]outfile.open("report.txt"); infile.open("people3.txt");[/CODE]
