Of course you'll need to access teh doctors appointments database for these scenarios. <br /> <br /> Or what you can do is to allow to make a request for an appointment and later manually inform teh status. But definitely the earlier method is much much better.http://forums.asp.net/thread/716172.aspxMon, 11 Oct 2004 17:08:05 GMT4c671506-2930-414c-a40b-8bf57ded5924:716172Zyess0http://forums.asp.net/thread/716172.aspxhttp://forums.asp.net/commentrss.aspx?SectionID=48&PostID=716172Now i use my mobile phone to book an appointment with doctor at a specified <br /> <br /> time (so my mobile phone now access the mobile website in order to do so) but unfortunately <br /> <br /> the time i specify is not suitable because doctor is busy at that time so in this case a <br /> <br /> person, e.g nurse, need to instantly inform me of this (so the nurse need to access the <br /> <br /> mobile website and send me a message regarding to this matter). <br /> So in this case i need to code directly inside the mobile website or other <br /> <br /> alternative ways????..........it is a bit like sms.....what i really want to know is that can mobile web <br /> <br /> application support two-way communication, which mean customers use mobile phone to book or <br /> <br /> whatever (client side), then we at server side can also send message instantly back to them <br /> <br /> just as the scenario described above......is it possible??? or which commands or methods i <br /> <br /> can refer to in order to make this happen??? <br /> <br /> <br /> I hope you can understand what i mean. THANK YOU.
