View 3 Replies[2008] Make Web Service Ports?
Feb 2, 2009I'm making an application that tracks jobs we log in our IT department and as I'm often out and about it would be handy to be able to use this app from my laptop and connect in to our server at our office. The problem is that a lot of the places I go block all outboundtraffic apart from port 80 and 443 (for HTTP and HTTPS). Now I know I could write an ASP.NET front end that I could just access over the internet but to be honest I just plain dont like making ASP.NET web pages and so if there is any way I could do this just through my standard desktop app that would be good.
I've heard a bit about "web services" and to me this sounds like a solution but I dont know enough about them to decide if I should use one or not.The main thing that will decide this is whether or not I can make this web service listen on port 80, is that possible?Also, is it hard work making something use HTTPS instead of HTTP so that the data is encrypted? I mean, do you have to do all of the encrypting yourself or is there some sort of automatic function you can use to handle this?

Mar 27, 2009I have been stumped on this for about 3 weeks now. In the beginning me and my partner have been trying to hit this at the internal angle. only problem is different html tables are constructed different than others. We are needing to extract from multiple pages and sites so we know that Regex will be the best solution. We can use the same script for everything. This is my first time working with Regex, I got it actually extracting the very first ip[proxy]. I have no idea why it isn't extracting every one on the page. I also have to add the . in between each each octave of the ip. That is weird because I have it in the Regexpession to find the .'s.What I'm Needing is for this to basically scan the whole page and grab all the ipsorts and add them to a listbox.Here is my

VS 2008 Checking To See If It Can Connect?
Apr 25, 2009i know My.Computer.Network.Ping but as alot of people know, it's glitchy and bugged.
I want something that checks to see if it can connect with something, as simple as it sounds.
I'm experimenting with sockets at the moment, but having trouble so i thought i would come and ask here
What i'm up to:
VB
IP = Net.IPAddress.Parse(getinfo("settings.inf", i & "IP"))
socket = New Net.Sockets.Socket(Net.Sockets.AddressFamily.InterNetwork, Net.Sockets.SocketType.Stream, Net.Sockets.ProtocolType.IP)
[Code].....
However the problem with this it that i pinged 1.1.1.1 and it still connects, ALSO i would like to be able to check a hostname not just an IP to make things more convenient, please help me to find a way to properly check a connection with IP or hostname.
Note: The getinfo function is defined by me
VS 2008 - Checking If Date Variable Is Not Set
Feb 28, 2010In the following code, a Date variable is declared but not set to anything:
Dim myDate As Date
What's the proper method of checking if the Date variable is "new" and not set to anything?
For example, getting the lowest date value from an array of dates:
Dim dtMostRecent As Date
For i As Intger = 0 To myDateArray.Count - 1
If myDateArray(i) < dtMostRecent Then dtMostRecent = myDateArray(i)
Next
In the code above, I need a way to check first if dtMostRecent is unassigned, in which case just give it the first value, after which it can be compared with subsequent values. How to check if a Date variable is unassigned.

VS 2008 Checking For Changed Text?

The Handler would be added after the data had been loaded. The question is:Is there another way of checking for text changes without having to add and remove 22 handlers.

VS 2008 Checking For Existence Of Registry Key?
Jan 6, 2010I am trying to have my program check for the existence of a registry key so I do not get a null reference exception error. The key may or may not exist depending on the computer. How can I check to see if it exists and then change its value if it does exist or skip over it to the next one if it does not exist? (I already know how to change the value part of it) Im just not sure how to check for the existence of it for example would be trying to set the value of a key that does not exist called test below... this obviously would throw a null exception error so how do I check for the existence of the key before executing these instructions and then if it does not exist it skips this and keeps going to the next code ?
Dim testkey As RegistryKey = Registry.LocalMachine.OpenSubKey("SystemCurrentControlSetTEST", True)
Dim keyval As Int32
' Set to ON
keyval = 1
testkey.SetValue("ON", keyval)
I also check the status of the registry entry on form load
Dim Test As RegistryKey = Registry.LocalMachine.OpenSubKey("SystemCurrentControlSetMYTEST", False)
'Get the reg value.
Dim Testflag As Integer = CInt(Test.GetValue("ON"))

if it is 1 then the selectedindex = 0
if it is 0 or does not exist then the selectedindex = 1
if RegistryKey2 is 3 then the selectedindex = 2

View 1 RepliesVS 2008 Checking Forms Design?
Aug 3, 2009I'm very green with VB Express 2008 and am going through the tutorial. I'm skipping over a lot of the exercises as some of it is review for me - I've a fairly solid background in MS Access VBA and forms design there. But I have a simple question on VB Express forms design (I'm not worried about data handling or anything yet).How do I test a form? In my first form on my project, I just press F5 (Start debugging) and it opens just fine. However, I'm playing around with a second form in design mode and can't seem to get it to open to test some of the code (simple msgboxes associated with buttons).
In Access 2003 and earlier, there was a design mode and form view. The Access design mode was the equivalent of the design tab in the VB project, but I can't seem to find the equivalent of the Access form view in VB so that I can open that form. VB F5 only seems to open the first form.BTW, is VS 2008 the correct tag/prefix for this question on VB Express 2008? I see there's a separate tag list - is there an approved list of tags aside from the prefix before the title in the posting screen?
