looks like you are compiling your program for UNICODE. Turn it off. Prject --> Properties (last menu item in the list), then expand the Configuration Properties and select General. Then on the right side of the screen change Character Set to Not Set

Some of those other warnings say that your program is downgrading a double to a long. You will have to decide which data type you want and either change or typecast it. In some cases typecasging will be ok, but in other cases it isn't. So you will have to make a decision on a case-for-case bases.

this is my new error build log
the warnings im not worrying about for now, just the linking part.

Look up those functions in MSDN and it will tell you what libraries you have to link to. Then add them to the project link settings. Just enter the function name in the search box from here.

[Slavrix]

to add em to the project link settings thats in project --> properties--> include --> additional library dependancies ?

[Garock]

since u seems to be using vc++, you might try using #pragma comment(lib, "user32.lib"), and try with other libs that way

[Slavrix]

thanky ou very much for your help guys its now compiling.

just gotta put in the static casts and then just gotta tweak numbers. cheers.
