PING!

Author	Message
Roger Sau #1 / 3	PING! -- I'm currently trying to validate a server address via VB4-16bit. I'm shelling out a DOS .bat file containing the following: "ping serverid > S:\VBDEVE~1\INTERF~2\!ping!.res" I have the usual 'round the houses' code to check when the task has completed, this works and I can then read the 'piped' file to dicover nuggets of information such as "Bad IP address server." No problem so far. Trouble is, after about 8 test runs of the program I happened to change application via ALT+TAB and discovered lots of DOS windows still happily sitting there, cluttering up the computer. Anyone know how to shell a DOS program and GUARANTEE to close the window on completion? Under WIN95 and NT ? NB I do not want to be checking boxes on shortcuts etc to close on exit, not unless I can do it via code as this will run on an unattended system and nobody will be there to click the mouse. Alternatively, how do I PING a server name via VB? remove NOSPAM to reply via email regards, Roger

Client Excele #2 / 3	PING! In the batch file make EXIT the last line of the batch file... But move on you need a TCPIP socket control for your VB Application.

Dave Lam #3 / 3	PING! check out Q129796 in the MSKB. It will tell you how to use the WaitForSingleObject function to simulate synchronous behaviour in Shell.
