Easy Way To Detect Internet Connectivity?
Oct 28, 2009I saw another forum which discussed how to detect whether a LAN was connected, but I need to know whether my Internet connection from my ISP is up or not (I'm writing a program for day trading, so knowing if my internet connection is down is critical). I know I can simply open a browser in VB and browse to a site and see if it doesn't come back "page not found", but that involves a fair amount of overhead, and if the internet is down, it often takes many seconds to a minute to come back with "page not found". Is there some simple command that will quickly tell me that my internet connection is working? I'm using VB in VS 2008, and currently using XP although I plan to convert to Windows 7 in the next couple months.
View 3 RepliesQuick Find And Quick Replace Dialog Windows For 2008 IDE?
Dec 7, 2010I am developing a VB application using the Visual Studio 2008 IDE. I was making changes to my code using the Quick Replace function when the dialog window stopped displaying. Selection of Quick Find or Quick Replace from the Edit menu, as well as use of shortcut keys (CTL+F and CTL+H) all have the same affect: the IDE loses focus but no dialog windows display. Is this a known issue with an available fix?

Aug 29, 2011Okay, I've been at this ALL DAY no one's advice has helped so I'm zipping up the simplest version of my problem and attaching it a silver dollar for anyone who wants a quick and (seemingly) easy problem. What it is:
frm1 loads with a button to start frm2(and populate a datagridview).I'm trying to save its data in the module in the example but it might not be necessary.Then another button closes/hides form2 and you can push a button on form 1 to TRY TO get the frm2.datagridview1.item(0,0).value.I can't do any more tonight.

Get A Quick Piece Of Code To Close All Non Visible Forms?
May 30, 2010I am starting to debudg my application in depth, and have realised that at certian points, if you close what appears to be the only open form, the application stays open. I was just wondering if there exists somewhere, a list of all open forms that you can view during debugging?Alternatively, is there a quick piece of code to close all non visible forms?
For Each frm In Application.OpenForms
frm.Close()

Setup DataTableAdapters To Allow For Easy Code Change When Change Server Names?
Feb 20, 2012I'm getting familiar now with using the Dataset Designer and how it makes for quick and easy updates and query of tables. I use to use the OleDB commands and leave the Connection String as a Global Constant so I can easily change it if the server name changes, or if we have to re-direct the .NET to another instance of the database.
But now that I use the Dataset designer I'm concerned that I maintain flexibility and support in the long run. how the Dataset designer works and where it stores it's connection string info? And how difficult that would be to update. It looks like I modify the App.config file, but I'm unfamiliar with this.
What am I getting myself into? It looks like a standard XML file. Is that it?

Detect ASP Session State Type From Code?
Jun 7, 2010I'm trying to track down a problem on our test environment. Previously it was set to use InProc Session State Type, but I've added in the SQLServer type for one specific Web App. I did this because we use the SQLServer type in our production environment and I want our test env to match as closely as possible.
However, after changing it to SQLServer I do not get any errors when trying to store unserializable data in session like I would expect. It works just fine, even though I would think it shouldn't. I'm a relative newbie when it comes to configuring this, but from the various tutorials I googled, I thought I covered all the bases.I was wondering if there's any code snippets to verify which session state type an application is actively using.
Getting Code To Detect The Operating System Running?
Mar 15, 2009I need code to fit for an 'if then' statement based on an operating system. So let's say I am running windows XP, the program detects it, and with a simple if then' statement it opens form2, if i was running vista, it would open form1. So basically i need something like: If (WindowXP current OS) then form2.open, If (windowsvista currrent OS) then form1.openOf course, the above statement won't work because I need code to support the detection of the O.S.Note: I just need code for just these two O.S'es, also I don't care if its Windows XP SP1 2, or 3, just as long as it's an XP.

View 2 RepliesUI-threading An Easy Way To Fix It?
Jan 23, 2012I am communicating with a USB-HID device. It will successfully complete hundreds of send-receive requests but occasionally get a Null Exception error.
[Code]...
at the rxData.dataPacket(i) = element I will get a NullReference error every now and then. I could enclose it in a try/catch statement, but I'd like to fix the root problem if possible.This device is communicating to microcontrollers, and it is possible that they won't always give a value... but my feeling is this is some sort of UI threading issue. When debugging, even though there is a null exception, many times there actually does seem to be data in dataReceived.data.ToList(). Is there an easy way to place the whole data processing routine on a thread separate from the UI?Edit: Changed code to match answer and give more info on where it is used. Still get NullReferenceExceptions after about 1,000 completed send/receive requests to the HID device.
.net - VB Flamed For Being Easy And Yet Python Is Not?
Sep 19, 2010I have always wondered about this and seen this among lots of programmers. Why is a VB programmer or VB code easily dismissed as too noobish and easy while the same does not apply to Python or Python code? After all, isn't Python as easy as VB is? And it does provide drag-n-drop GUI application building also. So why is it that VB is flamed and yet Python is not?

Apr 15, 2012I've been trying to play with DirectShow but it's getting on top of me and my question on here didn't answered so I'm thinking maybe I should go with a different approach. (DirectShow VB.net can't change recording format). <- Where as that 'works' I can't get it in the format I want it, and I don't really understand it so I'd obviousl like to go down the route of something I can get my head around.
I've googled till my fingers are raw trying to come up with an easy way to record video in my vb.net application, it doesn't have to be fancy, just a preview with a start record, stop record button, that's it.

Quick Search In A Richtextbox?
May 13, 2010I have a RichTextBox where I expect 100 characters per line. Each line can start with the letter A, B, or C. I may have thousands of lines and most of them will start with the letter C.When the cursor is moved from one line to another and is placed on a "C" line, I need to be able to quickly locate the nearest "B" line above it. It may be hundreds of lines away. A loop to search for the "B" line using GetFirstCharIndexFromLine(x) is too slow.
The user may want to paste many lines into the textbox. If necessary, a mild wait after pasting is acceptable.Do you have any suggestions for a technique to accomplish what I need to do? Even just a high level suggestion like "use a linked list"
