On my program I am trying to make a ToolStripStatusLabel's text change to "connected" if connected to a network and if not connected to a network change the text to " Not Connected" then I don't know how to display a image if connected to a network or not connected. So if the computer is connected to a network I have a image that I would like to be displayed next to the ToolStripStatusLabel. And if not connected to a network, can the program display a different image? I tried this:
My.Computer.Network.IsAvailable=True(ToolStripStatusLabel2.Text "Connected")
My.Computer.Network.IsAvailable=False(ToolStripStatusLabel2.Text "Not Connected")

I really like the coding speed that vb.net provides, but I don't like the possibility to forget to declare variable types, return types of functions, etc. and that is why in each class I use[code]..
Is there a way to define those two options on the project/solution level?

the combo box style 1 has both the drop down option but also a manual entry option. I need to know how to code it so that when you manually enter data, it takes that data and places it in a text message "The shipping charges for "data" is $15" displaying in a text box. Shouldn't be hard but have developed a mind block.

what does these two code means in vb.net: Option Explicit on Option strict on i think option explicit means the compiler is not going to do any kind of conversion and i need to do all of them by the code;also it becomes case sensitive i.e;

1. I have read that keeping Option strict on and Option infer off is good practice and will insure your code is tight and properly written. I would like input regarding this, pro's and con's from those who are in the know.
2. Having said that, I have set Option strict on and Option infer off in an existing program I wrote (that was working perfectly mind you) with them off and on respectively. I went through and cleaned up all the errors on the 'need AS' and casting of variables, but one is leaving me a bit put out.[code]
I have also read where using My.Computer.System.Directory.GetFiles() instead of System.IO.Directory.GetFiles() is probably not a good thing, but when I change to this I get no error, but also no dataI am thinking I should stay with the strict on and infer off but am really slogging through getting this code correct.Running Win7 on Dual Quad Core XEON Intel Extreme with 8Gb RAM.

I am writing a text editor program and I have written the new, open, save as, exit menu items but I am struggling with writing the save option.Now I have created the menu itself (well vb did, I just used insert standard items) but how do I code up the save menu option so that it updates the current document or if the documnt has not yet been saved bring up the save file dialog.Here is the code I have so far
Public Class Main
Private Sub NewToolStripButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles NewToolStripButton.Click, NewToolStripMenuItem.Click[code]....
I know I have some finishing touches such as messages and error handling and stuff but at the moment I want to get all the basics working,I think the save menu option is all I am struggling with at the moment.

Using VS2008, targetting framework 3.5, trying to update some VB4 code. Yes, VB4.I have a bunch of legacy code I'm trying to update, and I had the idea of trying to work through it by executing the old code, working out what was causing each error as I came to it, solving the problem, and then moving on.In order to do this, I have sinned and set Option Strict Off, Option Explicit Off and Option Infer On.Yes, I'm going to hell for this.Problem is, I'm still getthing errors that various things haven't been declared.All of these the items showing errors are in the form: itemName(obj)Is my problem that the compiler thinks that these are method calls for methods which haven't been declared?PS: For anyone wanting to tell me not to use these settings, I already know

I have to take over a project written in vb.net, which contains more than 400k lines of code written in option strict off mode. I want to build it under option strict on first before I do anything else -- which maybe converting it into C#. I found there's thousands of lines of code raises compilation error, mostly are about implicit type casts. Is there any tool would help to make it compile under option strict on mode if I don't want to correct every single line manually? Because it's really painful to add CStr/CInt invocation into every line of Code myself.

I have inherited a VB.NET application that I need to compile so I can run dorkumentation on it. I first received "Option Strict On disallows implicit conversion from x to y" errors, so I turned off the Option Strict option in the Project file.
So why do I still fail with the same error message?

But is it possible to remember the second choice when i change the first? the program should select the the option in the second if possible or other select the first option.[code]

i am trying to enumerate all IPs on my local network, but i am not having any luck. The only thing i have came up with so far is a really tedius "get my own ip and scan the subnet with pings" which surely isn't the best way? I am really only trying to get the ip of a tivo box, and i can determine it's a tivo by mac address or name. My router lists the "computer name" of the tivos as a long string of numbers with the prefix "tivo".What about broadcasting a ping packet? I could also attempt to connect with telnet to port 31339 on every one of them.

I'm viewing reports on a VB.net form using CrystalReportViewer. Once a report is opened, the Access database that is used within the report is locked (i.e., the Access MDB file can't be deleted). Even after the report is closed, the database stays locked until the VB.net app "ends". This is a problem because I want to be able to delete the MDB file at some point while running the app and can't. The VB.net app starts by opening a form named "Startup". No database connection occurs here. A button is pressed using this [code]I must not be properly closing the CrystalReportViewer or the Report form.How do I close the Crystal report and unlock/release the Access database?

My first post here in vb forums. I'm new to sockets programming since I migrated from Winsock and I learn a lot from Atheist. using his code, I can't access the messageReceived() every time a client sends a message on the server. but then I put a code to catch the message on sub doRead() and I can retrieve the message. My problem now is how can I determine if a client is still connected to the server or not so I can delete it on the ConnectedClient ?
[Code]...
Note: the server runs on Win7 x64 ultimate and the clients are laptops on win7 x86. I read a comment that the server should be having a static IP address, but when did it together with the clients, It still doesn't work. I am just using a switch for the network.

I know how to pull the fields onto the form and get the information to display on the form by clicking the binding navigator at the top of the form.
