Sign in to vote Hi ALL,This lot is my latest version.Built with the Express "Orcas" Edition,( which you can install alongside Visual Studio or another Express Edition ) from here. >>>>http://msdn.microsoft.com/vstudio/express/future/default.aspxor here>>http://msdn.microsoft.com/vstudio/express/future/downloads/default.aspxLeft-click on the filename Calculator_V2.zipwhen you download the project from here. >>>>http://efuncenter.5squid.com/Calculator_V2/I have now added the .exe file to the download area.Left-click on Calculator_V2.exe to Run or SAVE the file.Still not as many buttons. checkboxes and radiobuttons as the Windows version in scientific mode.It uses; 1 Checkbox 40 Buttons !! 1 Textbox 3 RadioButtons on 1 Panel 2LabelsI have kept it as simple as possible for beginners to follow.See a picture of the layout of it here. >>>>http://s13.photobucket.com/albums/a272/u-might-want-this/?action=view&current=Calculator_Pic.jpgI will try to put the project as a ZIP file on the internet for download, in case anyone is interested?Version_1.00 is in this
