My application is for visiting pass. This application is connected with intranet lan connection with 5 or more computer. The computer operator make gate pass at same time for multiple visitors. but how to do it i have no idea. like computer 5, application user at same time 5 , and visitor also 5 how to do if we want to make 5 passes at same time using 5 computer or more

what do you mean by at the same time ? if button is clicked at one instance then each computer connected in intranet should capture image from webcam? instead capture image at anytime but save at same location with timestamp or Guid etc.

Sachin Singh · Answer

yes after capturing the image give them an option of selecting the printer to print the document. if you willl print all documents by one printer then obviously it will print one by one , it completely depends on the infrastructure do you reall want to use multiple printer or just a single printer.

Does this mean that the computer operator has to set the default printer in his computer?

Sachin Singh · Answer

No not at all , we all are accessing this website at a time so , is there any problem. The only problem may come to printer settings each computer should connect to different printers if you want to print all the same time , meaning based on operator name your software dynamically change the printer name. otherwise no issues.

i have used web method to capture image using webcam. but i have one question when the all computer operator capture image at same time then what it is not generate any error ? because server is only one and access user is more than 5 when they access this application at same time from one server. [WebMethod()] public static bool SaveCapturedImage( string data) { //string hostName = Dns.GetHostName(); //string myIP = Dns.GetHostByName(hostName).AddressList[0].ToString(); //myIP = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"]; //if (myIP == "" || myIP == null) //{ // myIP = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"]; //} // string fileName = myIP + DateTime.Now.ToString("dd-MM-yy_hh-mm"); string fileName = DateTime.Now.ToString( "dd-MM-yy" ); byte [] imageBytes = Convert.FromBase64String(data.Split( ',' )[1]); //Save the Byte Array as Image File. string filePath = HttpContext.Current.Server.MapPath( string .Format( "~/CapturedImage/{0}.jpg" , fileName)); File.WriteAllBytes(filePath, imageBytes); return true ; }

Sachin Singh · Answer

Then what's the issue? You have already implemented the webcam functionality in your application then it will work for all computers doesn't matter how many concurrent operations are you doing. it will work in all situations , you are just overanalyzing that in parallel connection it will not work.
