View 10 Repliesi am working on a VB project for Chem and im making it for converting grams to moles, moles to molecules or any thing like that. and i have about 110 elements set up and working fine the way that im doing it but i have a feeling this is a horrible way and to abundant.
i have a textbox set up to if i type in the element He and hit enter it will find ChemElement(1)="He" and it calls "Sub DisplayElement(ByVal number As Decimal, ByRef label2 As Label)"
Which then displays the Chemical mass into a Label.

i have problem with searching key value in registry I have that
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim itm As ListViewItem
Dim root As RegistryKey
Dim searchkey As String = TextBox1.Text
[code].....
But on line: For Each valueName As String In root.GetValueNames, it says: Object reference not set to an instance of an object.
if it is possible for me to go to the specified listbox item via searching. Example;
Listbox1 items are
Apple
Banana
Guava
Pineapple
Peach
When I key in the word Apple in a textbox, the SelectedItem would go to Apple,
i want to select all items from listbox1 and then use that items for searching.if it finds the items, it will be displayed on listbox2 and if not, it will be displayed on listbox3.give a simple code for this? i am thinking of making listbox1 items into string so that it would be more easy for searching.
View 11 RepliesI have a listbox with multiple items:
Quote:
The Sopranos (Season 5) Boxset (DVD)
Braveheart (DVD)
MTV The City - Complete Second Season 2 (DVD)
I have a TextBox where a user enters a search:
The Sopranos Season 5 Since ListBox.FindString() wants a String and not a RegEx, I can't use a Regular Expression. (right?) So, if TextBox.Text = "The Sopranos Season 5", then ListBox.FindString(TextBox.Text) will not find my entry with "The Sopranos (Season 5) Boxset (DVD)".
I have a program which grabs the source code of a webpage and puts it into a string. I would now like to search the string for two values.
"video_id": "value 1 here"
"t": "value 2 here"
The problem, is that I don't know the position of the values, and I the values change depending on each webpage. All I know, is the text before the value, e.g. "video_id" and "t:"
Here is my code:
Dim videoid As String = TextBox1.Text.Trim
Dim wc As New System.Net.WebClient()
Dim result As String = wc.DownloadString(videoid)
I do not know if it is possible to implement this problem in VBA or it must be done with VB. Net using Visual Studio.
Problem: Excel has its search function and it is a pain if there many value available or you must find a value that far away from column A.
I would like to have something like this
In which I can specify what columns I want to display by their header name. Rearrange the column in the way I would like to, and ability to copy and paste. Like datagrid in Visual basic?
Right now im using
If ListBox1.FindStringExact(TextBox2.Text) = "0" Then
Label2.Text = "yes"
GoTo procheck
[Code]....
and it searches the first item in the listbox correctly but nothing else. Im assuming im going to need to loop through the listbox somehow?
I have a code to search through a listbox with mutiple search criteria. Here is the code:[code]When I search for something, how do I make sure I do not obtain 2 of the same results, If both criteria are found, or if all three are found?

For Each sWord As String In listbox1.Items
If textbox1.text.Contains(sWord) Then
but the problem is if the textbox1.text value is ( new text ) and the list box have like 3 items

it will return me 3 values i want it to return me only 1 value which is the exact text as textbox1.text ( new text )
I know the sort of a thread is already here, but I have a different question. I have ListBox1 and TextBox1 and the Items of ListBox1 are:California
Chicago Washington and as I start typing the text into the TextBox1 (TextBox1_TextChanged), then it will select the first Item in ListBox1,that is closest to the text in TextBox1:
For example:
If I type "A" to the TextBox1, it will select California (California)
If I type "C" to the TextBox1, it will select again California (California)
If I type "CH" to the TextBox1, it will select the Chicago (Chicago)
AND!!! If I type "SH" to the TextBox1, it will select the Washington (Washington)
so it won't only search the first letters, but it will even search the letters in the middle of the text, too.
I am using VB.net 2003 application program. I am trying to do a select statement whereby I'm searching between 2 datetime values that are being stored as datetime. records are stored inside Access. For example, I am searching between 2 datetime:
StartTime = 2/23/2009 9:00:00 AM
EndTime = 2/23/2009 11:30:00 AM
So I need to find all the records in between 9:00 AM and 11:30 AM on 2/23/2009.
strSQL = "select OrderID from Orders Where OrderDate >= ('" & StartTime & "') AND OrderDate <= ('" & EndTime & "') "
but i got the error showing below:
An unhandled exception of type 'System.Data.OleDb.OleDBException' occurred in system.data.dll
strSQL = "select OrderID from Orders Where OrderDate >= DATEVALUE('" & StartTime & "') AND OrderDate <= DATEVALUE('" & EndTime & "') "
But when I use DATEVALUE, it takes the date from the string and set time as midnight (00:00:00). So it returns no records between 9:00 AM and 11:30 AM on 2/23/2009, but I can see there are records. [Code]
strSQL = "select OrderID from Orders Where OrderDate >= TimeValue('" & StartTime & "') AND OrderDate <= TimeValue('" & EndTime & "') "
And when I use TimeValue, it returns the time from the string and set date as jan 1st. so it returns no records between 9:00 AM and 11:30 AM on 2/23/2009, but I can see there are records. [Code]
but none of the codes above is returning records between 9:00 AM and 11:30 AM on 2/23/2009, but I can see there are records. i searched and found all those examples. but that didn't work. Is there anyway i can search between 2 datetime values. i need to find all the records that lies between that time period (for example: between 9:00 AM and 11:30 AM on 2/23/2009).
Disable dynamic searching when typing in a listbox?
View 1 RepliesI will include a link to a copy of my source Code. The Problem is that I have to create a user management system. I have almost all my features working but there are one or two I can't get working. When the program loads a text file is read and the program lists the first name of everyone in the text file into a list box. I want to be able to get so that when you click a name in the list box, the persons information will be displayed in the text boxes to the left. And also when you edit those text boxes you can click the button for modify current and it will modify that persons data. The other problem I'm having is being able to search that text file for the users e-mail and return the first names of people who have that e-mail into the listbox.

I have to scan through documents. Excell, Word, txt, ect looking for company names that match a pre-difined list of companies.I then email the companies some specifics in regards to that doc.The problem I have been having recently is that the list of companies keeps growing and I am starting to miss some more than I used to.What I would like to build is a tiny app that has 2 Text boxes.1 on the left for input (where I would copy/paste) the document text I receive.and one on the right for the output where it will highlight any line that contains the name of any of the pre-defined companies.
I started toying with the idea and so far I have form with a SplitContainer. Within that SplitContainer each side has a TextBox... Below the Textbox on the left hand side splitcontainer I have a submit button with no actions currently assigned to it.

I am very new to vb.net. I have been using vb6 for a while and I am making the leap.I have a list box that receives entries from another text box, there will be multiple entries, and only some will be applicable per record(its a report writing app).e.g. The user says ok I need this and that signer for this record.
lstSigners.Items.Add(strSigner + strSigner)
The entries that are needed are then selected via checkbox in the listbox. I now need to be able to capture which items the user selected.

I'm trying to create a calculator that does this formula : Amount=Principal*(1+InterestRate) The point of it is to Calculate the compound interest earned over however many years the user selects between 1-15 from a listbox. The user also inputs the investment & interest rate. When calculate is clicked the results show in another listbox below.
year 1 $$$$$$
year 2 $$$$$$
etc
[Code]....
I stopped the code at Year 2 as it repeats the ElseIf to EndIf unitl selectedIndex = 15 & intYear 16.
it works for Year 1 but the problem comes with Year 2-15. it needs to take the value from the previous result in lstOutput and use it in the formula for principle.
I have a list box which gets populated on the first run of the program by the user. On the next run it needs to be completely cleared so new values can be displayed.
