There's a time to smile, and a time to frown. I try to smile all the time while at work as a WalMart cashier and often wear a happy-face sticker on each shirt lapel. I haven't been punched in the face yet for smiling :)

read [URL="http://www.devsource.com/c/a/Using-VS/Calling-Unmanaged-Code-from-Net/"]this article[/URL] Seems to me it would be a whole lot easier to use managed streams.

Has anyone tried to write [URL="http://support.microsoft.com/kb/307398"]this tutorial [/URL]using VC++ 2008 Express? The article claims to be written with VC++ 2005. But I thought 2005 and 2008 used compatible versions of CLR language. I'm getting all kinds of compiler errors -- for example [icode]String* str;[/icode] instead of using [icode]String^ str;[/icode] and …

Its the same as any other sort algorithm -- when you need to swap just swap Person pointer in the PersonList structure. It would be a lot easier to convert the linked list to an array of pointers into the linked list, then sort that array.

Learn the c++ language first -- don't jump into the deep end of the pool until you know how to swim. A program like you describe will take a firm grasp of the C or C++ language (could be in other languages as well).

The President is not a miracle worker -- although I think that was one of his campaign promises :) All presidential-hopefuls promise things in their campaigns that they can't possibly fullfill, or that they later decide are unworkable. And I wouldn't be supprised if Obama is the same.

You will learn a great deal more by writing it yourself instead of trying to copy someone else's work.

pass to function: its just a parameter [code] int foo(int n) { return n*10; } int main() { // This line passes the value 15 to the function foo() // and gets the return value in the variable named x int x = foo(15); } [/code]

You mean like this: Color coding requires the language option in to code tags [code=cplusplus] #include <iostream> int main() { std::cout << "Hello World\n"; } [/code]

>>If you need other pieces of the code I'll post them here... Please don't. Post all your technical questions in one of the language boards. I would move this to the right place if I knew what computer language that code was written in.

What variables do you want initialized? >>SendMessage(hwndListBox, LB_GETTEXT, a, etxt[a]); That's not correct, the last parameter is only passing a single character, not a pointer to a character array.

You didn't mention the compiler you are using, but assuming it is VC++ 2008 (Express) Select menu item Project --> Properties --> expand Configuration Properties --> General. In the pane on the right, the third item from the bottom, change "Character Set" option to "Not Set"

>>I do not know how to use FILE for writing data. Excellent :) Don't use it in c++ programs. Use fstream, ofstream or ifstream objects.

assign.cpp calls read_accounts() twice -- why??? line 87: >> strcmp(accountList[i].get_accountNumber(),tranAcct)==0; that should be an if statement -- without the [icode]if[/icode] the loop will not work correctly. [icode]if( strcmp(accountList[i].get_accountNumber(),tranAcct)==0)[/icode]

I think your formula is incorrect. See [URL="http://geography.about.com/c/ht/00/07/How_Convert_Fahrenheit_Celsius0962932698.htm"]this[/URL] [code] int main() { float f = 82; float c = (f - 32.0F) / 1.8F; cout << "c = " << c << "\n"; } [/code]

I compiled the *.cpp file with VC++ 2008 Express and got some errors [quote] 1>c:\dvlp\wintest\wintest\wintest.cpp(23) : error C2440: '=' : cannot convert from 'HGLOBAL' to 'LPSTR' 1> Conversion from 'void*' to pointer to non-'void' requires an explicit cast 1>c:\dvlp\wintest\wintest\wintest.cpp(61) : error C2664: 'SendMessageA' : cannot convert parameter 1 from 'int' …

I believe most programs contain language-specific dlls for each of the languages they wish to support. If its a MS-Windows gui program then put all the resources in language-specific dll.

Please describe the problem -- what does the code not do correctly? Or are there compiler errors, post some of the errors. And what operating system/compiler are you using?

Great idea, but I haven't the slightest idea how to do it.

[QUOTE=kangarooblood;908242]use the iomanip header [code=c++] cin.width(30); // reads max 30 characters/numbers cin >> input; [/code][/QUOTE] Nope, that doesn't help.

You call that c++ code ???:D My suggestion to you is to scrap it and rewrite in true c++ -- a program without all those C style functions calls.

The error message is quite clear -- you failed to code the function named get_record().

line 88 of the code you posted: You can not code a function inside another function. Write that function outside any other function then just call it on line 88.

c++ does not allow initialization of variables like that. No c++ compiler on earth will do it. What you might be referring to is [icode]const int x = 5;[/icode], which is allowed but not implemented by all compilers.

Its almost impossible to read .xls files directly because they contain proprietary MS-Excel data. But if you really really really have to do it then read [URL="http://sc.openoffice.org/excelfileformat.pdf"]this document[/URL] The simpler solution is to convert the xls files to cvs files using MS-Excell program.

Dev-C++ is not really recommended any more because it is no longer being updated and is already several years old. >>i.e. not for beginars. If you want to spend the $$$ for it, then buy a copy of VC++ 2008 Professional. [URL="http://www.embarcadero.com/products/cbuilder/"]Borland C++ Builder [/URL]is also considered pretty good.

Its not necessary to test for file existance beforehand. Just open like this: [icode]ios::in | ios::out | ios::ate[/icode]. This will append text to the end of the file every time the program is run. [code] int main(int argc, char* argv[]) { fstream out("HelloWorld.txt", ios::in | ios::out | ios::ate ); if( …

Its not calculating the average score correctly. It should be <sum of all scores> / MAX_SIZE. To do that you need another loop before the one you already have [code] int sum = 0; for(int i = 0; i < MAX_SIZE; i++) sum += scores[i]; average = sum / MAX_SIZE; …

line 11 of that code snippet is wrong. It should be delete[], not delete.

That was the title of the original thread.

There is a message in that compile.txt file that states it must be compiled with VC++ 2008 (probably express edition will be ok).

Must be some other problem -- your program works perfectly for me using VC++ 2008 Express on Vista Home.
