If ScheduledIn will be of type char (i.e. char ScheduledIn) then you cannot use double quotation marks in the if expression, use ' ' instead ... [code] char ScheduledIn; ... ScheduledIn = toupper(SchecduledIn); if (ScheduledIn == 'Y' || ScheduledIn == 'N')) { }[/code]

The client needs to specify how much data it sends, i.e. you have to use the value you get from fread(). The server must write only the amount it gets from recvfrom(). The return value of recvfrom() gives you that information. And last but not least, you must add error …

y is a single integer, so it cannot be passed to the functions as such. You need an array of integers holding the data you have read in. [code]int main() { enum { ARR_SIZE = 3 }; int y[ARR_SIZE] = {0}; // Array of ints, at max ARR_SIZE elements int …

Below is one option, maybe that is what you are after [code] private: System::Void button5_Click(System::Object^ sender, System::EventArgs^ e) { Form2 ^form2 = gcnew Form2; form2->Show(); } [/code]

obj must NOT be const because you intend to modify it, so use only plain gydytojas& obj i.e. [icode]friend fstream& operator>>(fstream& fs, gydytojas& obj)[/icode]

If you are going to set the value of mAccountNumber inside BankAccount::getAccountNumber(), then the function must be [B]non-const[/B], i.e. you need to have it like: [code]size_t BankAccount::getAccountNumber () { // set the value here ... }[/code]

BCB version 3 is ancient, really consider updating to much more recent version, a full version is available for free, see [url]http://cc.codegear.com/free/cppbuilder[/url] To convince you, given that ThreadFunct1 is a member function of the form class, the following code [icode]ThreadHandle[0] = CreateThread(NULL, 0, ThreadFunct1, this, 0, &ThreadId[0]);[/icode] should not even …

Shouldn't you rather be calling the setType() through the DO pointer instead of BP (assuming that the Base class does not and is not intended to have a setType() method), i.e. DO->setType("hello"); should work.

I think the original findHighest() code was working quite well, to get the actual highest score, simply use person[max].testScore once the index of the highest score is known (i.e. max in this case), so ...

If you need to copy a file, you can use System::IO::File::Copy()

The #import directive with Dev C++ is not doing what you expect, practically it is the same as #pragma once i.e. related to include guards instead of type library imports. See e.g. [url]http://www.delorie.com/gnu/docs/gcc/cpp_54.html[/url] If you really want to tackle Office automation, you could switch from Dev C++ to a free …

<<then the program will print to the result.txt A (last line ,transformed) The reason why this happens is that the push() uses everytime the same buffer (=record), so effectively the stack contains pointers to this single buffer, and what was last written to the buffer, gets printed to the file …

I think you should forget trying to use a String to store and restore a color. Instead, you can simply use a member variable of type System::Drawing::Color to save the original color and restore it back when necessary. So in your Form class, add a member variable like; [icode]System::Drawing::Color ColorSaved;[/icode] …

I suggest that you familiarize yourself with the concept of passing by reference, including passing by const reference. And while you are at it, check out returning by reference too. Now you are passing vectors by value into functions that are supposed to modify the input, however, that simply will …

Just a suggestion, have you considered using a struct/class the encapsulates the data of a single item? You could then operate with a vector of such struct/class instead of the many separate vectors you have now. E.g. [code]struct Item { string ID; string Name; double Price; }; void getData(ifstream& infile, …

vardas is an array of 25 Strings. So if you want to keep it that way, you need to use something like: [icode]gydmas[1].vardas[[B]some_valid_index_here[/B]] = Edit21->Text;[/ICODE]

Sure you can write your C++ code using notepad, it's a text editor after all. But you need to have a compiler/linker to turn the code into a program which you can then run.

You need to randomize the hillsize and gridref values within the loop in which you initialize the list.
