Updating Label From DGV Item?
Jun 10, 2009
i can grab the value of an item from a datagridview but i cannot change a label with that value. don't know why it ain't working.this works, the msgbox displays the value i click.
Private Sub DataGridView1_CellContentClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick
Dim row As Integer = DataGridView1.CurrentCell.RowIndex
[code]....
but this does not work, the label does not get updated.
label23.text = DataGridView1.Item(column, row).Value
could it be because that label is on another tab from the DGV? should i reference the other tab?i tried TabPage2.label23.text = DataGridView1.Item(column, row).Value but of course it's not working.

What I am trying to do is update a label with a value from a sql table using a combobox.this is a record from the table concerned
Species_ID (PrimaryKey) | Species | Genus_ID | Avg_Length | Avg_Height | Est_Weight | Diet_ID
1 rex 1
46 18 14000
1
On my form I have a combo box that is bound to this table with Species_ID as the Value Member. When I select a value from the combo box I want to update 3 labels with data from the Species_ID row corresponding to that value.

I have Data coming in through a serial port and it consists of pretty much all numerical values except for a few begining response characters. Its a Load Cell which spits out Tension in Pounds. I'm making a simple terminal program with the ability to log the Incoming Data for record keeping and data plotting. I want the incoming Tension to be displayed on the screen real time.I can get it into a text box and have it scroll indefinetly as it updates the data,but I'd like to keep it localized in one Label. I can display it in the Label but it wants to scroll down as it comes in. I want to keep it refreshed in one spot if that makes any sense. Heres what I have thus far. It will put it in the Label but wants to scroll like in the textbox. For example if I send #00F0 followed by a carriage return it replys back with whatever is displayed on the Screen which usually is the tension.it says "01TK 00.074 LBS" no quotes.. for a reply.I'm assuming it needs to be stripped down to just the numeric characters first.'here is what gets sent to the Load Cell to tell it to output data fast as it can to the serial port.[code]

Using VB 2008 Express.
How would I create a label that reports a file size at all times? Or, on a regular basis, say every 10 seconds or so.
In my form, I want a label to watch certain file sizes (logs, etc.) in case one suddenly becomes too big.
It is easy enough to report a static file size when a form launches, but changing it dynamically...I don't know how to do that yet.
The following example is generic and simplified for illustration purposes.
The file is C:Applicationapplication.log
The label might include:
("The application.log file is {0} bytes.",GetFileInfo.Length)
or something like that. But that would report a file size once and never again unless I quit and restart the form.
If any .NET concept is used, can you provide a link to the documentation or msdn stuff?

I've been programming in vb.NET for a whileAnd to be honest, its turning out to be a real pain.Here is the
Form1.vb: Imports System.Threading
Public Class Form1
Dim trd As Thread[code].....
So, I have a form (form1) with a label on, this label simply reports the status of the thread.The thread begins the Class1.Main() sub, and I have a delegate setup to change the text propoerty of the label.Now,I know the label is created on the UI thread,so I assumed the delegate would work. However,it seems that it updates the .text property, but doesnt redraw the control when .Update() is called .What am I doing wrong?I have found lots of examples of delegates, but all run from within the same class. I want to use threads too, not a backgroundworker! This code is a "simplified" version of a project I am on, which is encountering the same problems

We are working on an asp.net 2.0 web app that emails users an ical to save to their outlook 2003 calendar. We noticed none of the code to update or delete an item seem to work even though the ical 2.0 spec supports it. We are curious if Outlook 2003 just ignores this?Does Outlook 2007 act differently?We have situations where an event may change or be cancelled which fires off an email notification but the updated ical just adds a new event, it nevers deletes and or moves the original.

I'm trying to program a calculator, of sorts, that you would input amount of gasoline and cash or credit, and it calculates the total and the place where it is cheapest. I've gotten everything down, but for certain places, depending on cash or credit, and gasoline amount, gives rewards, such as discounts, gift cards, etc. I'm trying to get the free item to appear in a label, but i'm having problems with it showing up the wrong gift.

I am attempting to create a program that opens a file and reads the contents to then display them in a set of four text boxes (e.g. id, firstName, lastName, avg.Salary). it stores the data in an array.
i have done all that i can do, however, i wish to display in a label something similar to this "5/10 (5th record of a total of 10)" meaning the 5th record in the array out of a total of 10 records. i have already done the code to display the total amount of items in the array, that part was simple, but i can't get my head around trying to code something that will display the record that i am currently viewing in the text boxes.
i have a "view previous record" and a "view next record" button that will go through to the next or previous record, in doing so will change the "5/10" records to the next appropriate number, e.g. "5/10" goes to "4/10" if the previous button is pressed (in doing so, obviously the records that are shown in the text boxes will change to the next or previous record)[code]...

I'm having an issue wherein after I run a search filtering a datagrid, the corresponding datadetails will not update anymore when a new item is selected in the datagrid.I would like it so after clicking an item in the datagrid, the details update automatically.
[URL] The problem is, after running a search (or hitting 'show all') the label/details no longer change when selecting a new item in the datagrid.[URL]
Private Sub Sheet1BindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
Me.Validate()
Me.Sheet1BindingSource.EndEdit()
[code]....
To clarify, the search itself filters the datagrid perfectly as intended....it just seems to stop the details from updating when new items are selected which is my problem.

I have a list of names in a database and what i want is to get all of these names and display them in a label or a text box to the user on the website. I have tried to do this using a for loop but it is always overwriting the label each time. I have a list of 10 different names in the database and what it is doing is putting the first name in the label and then overwriting this with the second name and so on until it reaches the last name. I think i need to store each of the names from the database into an array or an arrayList and then make the label display all of the contents from the array or arrayList. The for loop i have used for this is:
Dim g As SQLadmin = New SQLadmin()
g.DB("SELECT nameOfPerson FROM Persons")
For i As Integer = 0 To g.array.GetLength(0) - 1
[code]....
i can select the names from the database and store them in an array then make the label display each of the names.

I have a list box on the form which functions as a copy/paste. When you copy something, it is automatically added to the list box as a "clipboard helper". Here is the problem,however: if the text is more than 1 line, the list box does not show all the text.It ends up looking messy.So getting back to my question, is it possible to make the list box item height for an item depending on the amount of lines that item contains?This is a one line sentence in the list box and should take up one line.This is a multi line sentence in the list box and should take up two lines for item height.

I have a webpage with a form that is used to edit some object. This object contains a Collection of other objects defined like this: Public Overridable Property Employees As List(Of Employee)
On a form I can delete an employee, add a new one or modify existing one. When I click save new values are sent to the server. On a server I check if the user exists. If exists then I modify its values, if it does not exist then I add it. All employees that exist on the server and were not sent are marked as deleted (State changed to EntityState.Deleted). I try to use the following code (dbCollection = database entities, newCollection = collection sent from the form):
[Code]...
This code does not work, because changing to EntityState.Deleted removes the object from collection, and for each loop breaks, since the collection is modified...I know that I can overcome this problem by using a for loop or adding objects to delete to some other list first, but I hope maybe there is a pattern that would make my code nicer.

Is it possible to compare 2 dataitems and then display the result depending on the 2 values using if eval at run time?I have a ListView with databound controls. 1 is RedemptionChoice and the 2 is CashBack.When 1 reads "0" and 2 reads > 0.00 the output should read AUTO I have read many comments online and most point to create a new function within code behind but have found it impossible to implement on my own.I tried this as a test on the actual page:
<%# If(Eval("CashBackRedemptionChoice").Equals("0") & Eval("[CashBack]").Equals("0.00"), "Auto Cashback"))%>
2 needs to be greater than 0.00 for AUTO to be displayed. Hence I know this would not work. Just trying to give an example of what I would like.
