I am very new to VB and was thrown into the water with a very big project done in VB.What I am trying to do is this:1. The initial search is for locations within an area of 200 miles.2. If no locations are returned search for locations within 500 miles.Seems easy enough but I cannot seem to figure out how to do part two.If thunder.apps.ddr.franchiseconnect.bll.Current.Settings.Location.hasValue Then'we run this procedure to get the location's value from ZIP db for lat, long assignment
First I should say that I have just started to use .net and have made some good headway with my first project. However, I have come to a bit of a block. I need to set the path where files will be searched for based on whether a radio button is checked or not i.e radio button 1 is checked = path is c:apple, radio button 2 is checked = path is c:anana. I am using this little bit of code I found to search for the files and it all works fine until I try and put the Dim path as String part inside a conditional and set it as Dim path As String = ("c:anana").
I have a textbox that a user can type in an ID to search for in a database. It currently just checks for 1 ID.[code]And now this is where my question comes into play. How can i create a query based on how many ID's the user inputs into the textbox?
I need some help Adding a search button in VS 2010 VB.Net application linked to an Access Database...
screenShot:
what i need is I want to put the ID in the TextBox besides the search button,and when it finds the ID ( which is the PhoneNumber here ), it automatically fills the fields below with the correct data from the ID found...
I've been working on some autocomplete abilities for a webbrowser I'm building, rather like in IE or Firefox. This is what I mean: I have absolutely everything working - adding search providers from webpages, getting the search suggestions as an XML file from whatever provider may be being used, and adding them in a multithreaded manner to the combobox with all the suggestions in it.
But there's a problem. Due to the fact that the search suggestions are only retrieved (in a matter of milliseconds) after the user has typed something in the Combobox, the suggestions only flicker up, as they are modified just after the text is changed, therefore I get an effect like this:
Again, I'm pretty sure I'm getting this effect because of the fact that I'm adding the Auto Complete suggestions to the combobox right after the text is changed - so they just hide themselves again - and this process is repeated. Does anyone know any way in which I might be able to stop this disappearing from happening? Because I've had a good think about it and I can't really think of any workarounds.
I am Looking for a combobox that does a full search and O mean by that the following : It starts searching data upon inserting or adding new character to the textbox of the combobox and vice-versa, which means that if I moved back by deleting a character then it starts searching again selecting the first data resembles the textbox. In another way I want a combobox class does exactly the same as combobox in Encylopedia.
I'm having a problem with part of my application I'm trying to get the directory entry for a computer object in AD (it could be mutiple computer objects based on whether or not the users passes a wild card for the object name). These names would be added add a child node of the parent node "Computers" in the tree view. I'm just having problems with using the search results...
Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim parentCNNode As TreeNode = New TreeNode("cn") TreeView1.Nodes.Add("Computers")
i have a listbox, that i want to make sure the value im about to add to it, is not already in the list, here is what i have but it dosent put anything in the list box.
For Counter As Integer = ListBox1.Items.Count - 1I To 0I Step -1I If InStr(CStr(ListBox1.Items(Counter)), hyperlinked(0)) < 1 Then ListBox1.Items.Add(hyperlinked(0))
I made a Search Button on my TableDataGridView, which is MemberID... i add query and in MemberID Filter i put LIKE @MemberID + '%'
My MemberID Data Type is Varchar50 / System.String and i also remove this in the form ' Me.REGISTRATIONTableTableAdapter.Fill(Me.PSCDatabaseDataSet1.REGISTRATIONTable) ..
The template I use for all of my pages looks at the style.css to get the header image. I want to change it so that it looks at who logs in and displays an image based on who they are.
Is there a way to set a variable in VB.NET in an IF statement. I would like to do the following:
[Code]...
Is there some way I can get the last "ElseIf" to work? I know I can re-write it to get it to work but is there some syntax that will make it work the way it is?
In this query against a datatable i'm trying to do some conditional filtering.The check against Timeband(index N) should only be done when the Index exists. (the base code only had three item fields, i've converted them to a simple list)
Dim res As DataTable = ( From dr As DataRow In dtTimedRow.AsEnumerable() Select dr
[code]....
The above code triggers an Exception if the count = 1. It executes the code next to imeBands.Count > 1 which it should not. What would be the correct solution for this code.In the mean time i've added a simple filter function.
I have a datagrid in asp.net and vb.net, and i'd like to show the status of the item of a certain row with two possible icons.I have a function that checks validation and returns a boolean value that uses some fields of the datagrid.
I have some textboxes on a report in VB 2005. There are three "Status Types": A, B and C. I want an expression like this to work on a number of textboxes:
I have two combo boxes: cboRepairCategory (plumbing, landscaping, etc) and cboVendors. I am using Stored Procedures in SQL to store the data from my database and then load them into the combo boxes.The cboRepairCategory will be loaded first. Once the user has selected what type of repair it is I want it to restrict the amount of vendors that can be selected, so instead of saying:CREATE PROCEDURE dbo.up_Fill_Vendor_Combo
AS SELECT VendorID, CompanyName FROM Vendors
[code].....
I would select only the vendors that have the RepairType of say Landscaping, so thecboVendor would load now only Vendors with Landscaping instead of all vendors.My question is this: Is this done in SQL in my Stored Procedure or is it done in VB in my functions for my combo boxes. I've never tried this before I am totally lost on it. I have fiddled with the code on both ends but to no avail.
I have a DGV that is bound to an Access DB DataTable. I have added a column in the DB that is either a 0 or a 1. When the program loads, I want to change the backcolor and forecolor of each row based on the value of this column's cell. ie: a 1 makes the row red, a 0 makes the row green. this column would be hidden in the DGV.
Is this possible to do at runtime even though it is bound?
I'm not sure when I would actually do the color swap, formLoad?
Second question, as I iterate through each row of the DataGridView and need to change the value of this column, will this update my DB automatically, or do I need to call an update() after each row?
In Perl (and other languages) a conditional ternary operator can be expressed like this:my $foo = $bar = $buz ? $cat : $dog;Is there a similar operator in VB.NET?
I want to be able to call forth hundreds of different photos be selecting them from a listbox or something of that nature.
Normally, if I only had a few images, I would amke their visibility false and then use If statements to turn on their visibility once it is selected. However, putting hundreds of images on to a form and then changing their visibility, seems like a pain.
I was wondering if there is a way to call forth each photo within the resources folder when an item is clicked so I don't have to put each one directly on the form.
Quick question, of which the quickest and easiest answer may well be to rearrange related code, but let's see...So I have an If statement (a piece of code which is a part of a full working solution written in C#) rewritten using VB.NET. I am aware the VB.NET IIf(a, b, c) method evaluates both b and a regardless of the trueness of the first evaluation, but this seems to be the case in my standard construct, too:
If (example Is Nothing Or example.Item IsNot compare.Item) Then 'Proceed End If
In the members region I declare _Name and assign it the value "NameA" but how do I assign this value conditionally?The idea is that if in some file there's a value set than that should be the default value and not the hard coded one, if non is set the hard coded one should stick.
#Region "Members" Private _Name As String = "NameA" #End Region #Region "Properties"
Is there a way to conditionally format an Excel Chart? For example I have a bar graph. Currently I have the bars a purple color. I would like to turn a certain bar red if it meets certain criteria. Is there anyway to do this?
I want to display an image if 2 conditions are met. The data item is not null.
