Creating Button To Search Wireless Networks Or Ping
Oct 13, 2010
I am using VB 2008 and doing the project on office 2007. I've created a Ribbon (Visual Designer) and put a button. Now thats all I've done. I'm still researching on how to make it so that when I press the button , a box will appear and at the side of the box will be something like" Search, Stop, Select, Cancel" buttons the box will be a container where when search is pressed, the wireless/LAN connections will be displayed.
I would like to create my own application that will simply discover the wireless networks in the area, similar to how the wireless card software works. I don't really know where to start, except with maybe the System.Net namespace.
I'd like to build a program which shares files between two computers. My method for doing that is setting up a home network, basically, on one computer, put a file there, and share that file on the network. The other computer would then connect to the network (through my application) and find the file and read it. I know this is very long. I would just like you to help me start up.How do I create a wireless network ENTIRELY THROUGH VB during the initial setup of the application? I don't want the user to deal with creating the network himself.
I have been trying to figure out how to get my code to work. (It was a homework assignment which has already been turned in but I am determined to get this code to work.)I have a text box titled txtSearch and btnClick.I need to search a list box for a city name and then have it displayed in a message box. If there is not a match then I need to display an alternative message box stating there is no match. City is in the list box starting at 16.The text needs to be case insensitive.I am only getting the message "That is not a valid city." for any entry that I type into my txtSearch even though I know it should be a match.
Here is what I have for code
Private Sub btnFind_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnFind.Click ' Declare variables to find text on txtSearch when button clicked Dim length As Integer = txtSearch.TextLength Dim value As String = txtSearch.Text.ToUpper
i have tried altering some code i have to ping an ip address and store the result in an access db.i had it working when i had the ip hardcoded in as a string but I am now gettin an error.instead of having the ip address hardcoded in to the code i want it to be read in from the access db but im now getting this error:System.nullreferenceExceptionbject reference not set to an instance of an object at...button1.click event args ei have underlined the piece of code i tried to change
I'm very much a beginner programmer in Visual Basic 2008 Express. I am trying make a program that when a button is pressed, it pings a set of IP's, let's say in Listbox1 and have it go down the list of IP's. The good ones will be added to Listbox2. I would like to know how I can have the listbox contain multiple lines as well as getting the ping information to check if the IP works or not. Then if the IP is up and running it will add it to listbox2.
I'm creating a search function to search through a binary file and find a record based on the users input. Surprisingly, that isn't the problem! The problem I'm having is that as part of this I'm using a procedure to display results in text boxes, and I'm getting the error "Too many arguments to private sub display customer"I've encountered this error before, but never really knew what it was... Here is my code.
Private Sub btnSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearch.Click FilenameCust = "F:\College\CustomersFile.bin"
I have a datagridview with 2 columns, 1 is Batch_Number and another is Existing_Stock, there is about 6000 rows.My question is, I want to be able to write in a TextBox and hit a Search Button to search the Batch_Number column and filter out or highlight the row with the matching number to see the Existing_Stock
I'm using SQL as a database in VB 2010, I already add a table to my form as a datagrid view but I don't know how to add buttons for filtering, deleting and adding things in my table, for example I want to have one button on my form call it search button to search in table names or Phone Numbers. how can I do that and where shall I write the code?
I'm in a bit of a quandry. I am trying to build a simple search form where the user selects the column title and in puts the criteria then clicks the search button. This is the code I am using

I have a MS access database connected to a VB2008 developed software. I want to make a search button to search through all the tables in the database. how can I do this?

I have a matrix for example (10 x 10) which represents 10 nodes. The matrix called MyMat(9,9) The rows of this matrix represent the source node (From Node) and the columns represents target node (To Node). It has 14 links which are randomly distributed. The non zero values represent the connections between nodes.
I am working on a video chat program and I have almost everything working on my network I now need to figure out how to establish comunication between two clients from diffrent networks without having a middle person to switch each meassage to each other.
To clarify: I belive that I need to have a server running that each client when they start up the program will login to the server handing thier external ipaddress and port forward to get to each respective client, this will be stored in a SQL database (I know how to add the data just not hwo to get it from the source)
Then the server would brodcast the clients name to anyone that is authorized to know (currently everyone) and has there data stored on the server.Finnaly when the client shouts down it sends out the logging-off comand and deletes the adressing information from the server.The client programs will be windows form applications that use the tcpclient connection to send text meassage And the server application will be I hope a webapp.
I have a form with two listboxes. The user selected the directory using a FolderBrowserDialog1 then my program searches the directory and displays a list of files. They them select the files they want to store under a project name and the names are placed in a database. My problem is it stores the mapped file path not the network path. (ie N:examples estfile.txt I need \myserverexamples estfiles.txt) That is because the person that reads this database may not have their network drives mapped to the same letters.
I need test data for a IP Subnet calculator I have developed. I have tested some obvious scenarios, and all seems good, but the person developing can often be the wrong person to test.
The calculator can do one of two things: 1 - Given an existing network and CIDR (mask), and a new CIDR it will create a number of networks with the appropriate number of hosts. 2 - Given an existing network and CIDR (mask), and a list of c,h, (c = count, h=number of hosts) it will create the networks.
I have written some software for a company I want to start, basically I want to supply automotive parts. The software I have created uses a database to hold information for users, parts, suppliers and so on.I want to write in a search bar so I can search for a part by name.The code I have written so far for this form is basically what is created when the new dataset wizard is used.[code]I have a datagridview that loads the data for my partslist table, underneath there is a textbox control for my search bar and a button to perform the search, underneath that I have placed another datagridview control to receive the results from the search.Can anyone help me write code to perform a search and place the results in the second datagrid control.
I have been asked to write a search screen for a rooms booking application.I have kept the design nice and simple so all the user has to do is enter the dates they want to book a room for and the results are shown in a datagrid view, if no rooms are available for that date a message is shown.I have absolutly no idea where to start with the code.I have written the code for the connection to the sql database, but this is as far as I get, everything I have tried so far just hasn't worked.
there anyway to retrieve the SSID of the network the pc's currently connected to or the list of available networks? I've googled for examples, but I only find vb.net 2005 examples that don't work in vb.net 2008
Lets say a search engine is doing a search by date range. If we want to further expand the search by decreasing the date range by looping with date range one month close to end date how would you change the parameters?
For example if these are the date parameters:
start date = 05 / 07/ 2009 end date = 05 / 07/ 2010 050709 - 050710
Thats my set range; so now I want to change the range by month like this
i am creating a search system i have one of y search querys working but when i try to do the same on a different part of the project i get this error message and one of my text boxes underlined message is : -

i am trying to create a search function/filter for a list box basicly when i type a letter or letters into a text box i want the listbox items to be filtered so say i have 5 names in the list box as follows:
I'm creating a search control where searches can be compounded. So, for instance, I could create a search for Orders where OrderID = 1232 or OrderID = 2343 and OrderID <> 23435
So I have a button that users can click to compound. Obviously its a complicated problem to do well, but in any case, on my path to trying to find the best way to do it, I wanted to create a variable that could be either '=' or '<>' depending on the value of some other variable set elsewhere.Is there a way to do that? Or do I have to switch to Expressions?
I created 2 forms in Access 2003 (Form1 & Form2) for the purpose of creating a 'smartform' of sorts for my company. In essence they can click on a search feature in the top cell and input an employee ID # which automatically fills in about 10 to 15 fields.
- There is only 1 table attached to the forms.
- The group I created this for is uncomfortable using Access.
What I would like to do with VB.net:
- I thought I would create an internal webpage using VB.net so they wouldn't need to log into Access [the DB would be stored on a separate server.]
- I would need a clean & simple interface that has 2 buttons, one for each form.
-When the form is called up I would need a search feature "EMPLID _________" which would connect to the Access DB table and retrieve the correct information.
-Id also need to have the form printable & have the ability to search again or return to the front page.
I am developing an ASPX VB.NET file using SSMS 2008.I need to add a search textbox so that users can filter SQL records on one of the columns. I have been working on this several hours and although I have the SQL records returning correctly now, the search functionality is not working. I do not get error messages from this code,
Here is my ASPX file code: <%@ Page Language="VB" Debug="true" Src="../Global.vb"%> <%@ Import Namespace="ChartDirector" %>
I have already written a code to search for staff records from my staff database and it's working fine, but the problem is, if someone enters a wrong a wrong staff id or just any number or alphabets, it still displays the "Found Record" message, instead of "No Record Found".Please I need to write a check if a valid staff id is entered in the search textbox and if its invalid, "No Record Found" should be displayed.
Here's my code below. Private Sub btnSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearch.Click
