Please use [ code ] [ /code ] tags (without spaces) when posting code.

Most probably a network issue. Add Log(LastException) to Socket1_Connected to see the error message.

I will use it just not remembering the [ode] (i used spaces).
Using VB6 Server I found I get that computer's IP is 192.168.43.1
Here is the view (if any information given, leopardise my PC's security , please delete them)

I'm sure that the problem is related to Windows 8.1 settings but don't know what to do in order to make it work. I use on the same PC the VMWare running windows7 and all things works ok (on WIndows 7, the Server's IP is 192.168.1.196)

run your server as administrator?

Hello,
I'm watching this thread with interest. If you find a solution please let us know.

I had a slightly similar problem recently – there are many differences but I bet the solution is somewhat related.

On a new Windows 7 computer using B4J my app connected via the net to a third-party Web server. It didn't connect properly on my new computer. I posted the question, Erel replied: "Works for me!"

I tried the same B4J program on an older, heavily used, Windows 7 computer and it worked.

There must be something about my network configuration on the new Windows 7 computer that causes this error. I'll bet it might be similar to your Windows 8 problem.

Barry.

Hi,

no probs so far on my WIN8.1 64Bit.

Could you upload both? I would test it on my machine @home.

Question: What is this address good for: 192.168.43.1? I would have expected 192.168.1.43...

As I have understood this, the subnet mask must be 255.255.0.0 in that case? 255.255.255.0 would filter it (254 possible addresses)? Probably I'm wrong...

Did you try all 3 ip addressess?

That echo tool might only bind to 1 IP address.

Temp. dissable the 2 vmware nics so that the tool grabs the 1.x address,
enable nics again and give it another try.

Klaus: you are right, the mask might need to be modified to reach the other subnet. But as traffic comes in in this case it shouldn't matter I guess.

on the other hand, if the phone/tablet is in the .1.x range it will never reach the 43.x one unless you change DHCP settings.

@mbatgr Your computers ip is 192.168.1.184, not 192.168.43.1 (That´s from VMware-Machine (possbly an emulator?))

 

[sorex]

it's the vmware host nics used for bridge and other modes.

it seems that the echo tool is grabbing its IP from one of these 2.

THanks guys for the help...I deeply appreciate it
