VS 2008 - Taking Column And Adding Input Elsewhere
Nov 15, 2009
I am working on a program where the user inputs values, then the program calculates those values and outputs the sum. When the user hits the button exit then those values entered by the user are saved. When the user starts the program again, the values are still there. I wrote the code and everything works fine. I am saving those values in notepad... and the program grabs the input in notepad and outputs those values to the program. But here comes the problem: Lets say the user wants the information in a certain column to be added to another column somewhere in the program. Is that possible ? And if it is can it be done when I am saving those values in notepad?

I'm writing a database program that will take various information from the user via text boxes, then save them as a *.txt file. I've already figured out the majority of that business. However, I'm having trouble programming a ListBox.
The ListBox needs to accept three pieces of information from 3 Text Boxes, then concantenate them when a button labeled 'Add' is pressed and scoot them to the ListBox (lstshowresults) while clearing the three boxes at the same time.

I am trying to add some style properties to a column but the code I am currently using doesnt seem to work at all?
Dim oApp As New Excel.Application
Dim oWB As Excel.Workbook = oApp.Workbooks.Add()
Dim oWS As Excel.Worksheet = CType(oWB.Worksheets(1), Excel.Worksheet)
Dim style As Microsoft.Office.Interop.Excel.Style
style = oWB.Styles.Add("Style1")
[Code] .....
It's still the same as "default" would look when just opening up excel for the first time.

I am dynamically creating and adding a ComboBox to a specified column in DGV. I also set a DataSource, DisplayMember and ValueMember for the created ComboBox. Somewhere else in my program, I select a number ( let's say 5 ) and based on that number I want to change the SelectedIndex of the current ComboBoxColumn ( I actually loop through the Columns collection ).I tried something like this in a event handler I created:
vb.net
Private Sub combobox_validated(ByVal sender As Object, ByVal e As System.EventArgs)
Dim combobox As System.Windows.Forms.ComboBox = sender
Dim colIndex As Integer = combobox.Tag
[code]....
You will notice here, that I'm not actually trying to change the .SelectedIndex property, but the Value of the current cell.How do I reference the actual ComboBox?

I've been working on some code to add together input from an input box to make a string and display it in a message box. I've put the code in a loop so that it will add all input into the string until nothing is entered in the input box.
Dim stringInput As String
Dim message As String
Do Until stringInput = String.Empty
[Code].....
All I get is just the last input entered to show up in the message box and none of the previous entries. How do I get all the input to be added together and show up in the message box?

I have a table adaptor that pulls from the sql database, when I edit the table adaptor query it makes this specific table adaptor not a part of the dataset. I have added a column to my database which will contain an integer, when I try to add this column to the query this error occurs, i am using the configure area of the table adaptor.
Error 'AuditProductsTableAdapter' is not a member of 'MemKingClient.MemKingDataSetTableAdapters.TableAdapterManager'.

Is there a way to use ReadAllLines to read in a text file that contains some Chr(10) (linefeeds) but uses ONLY the Chr(13) (carriage return) as the true end-of-line?What I mean is, DON'T treat a Chr(10) as the EOL. ONLY treat a Chr(13) as the EOL.Obviously I could just read in the whole file as binary and then split it into lines by scanning for Chr(13), but I just wondered whether or not there's a setting in VB.NET to set the EOL character so I didn't have to do that.

I have wrote a program that uses sendmessage to automate clicks. I have also made it where it can minimize to tray, hides form & shows an icon in tray. The problem is that when it's minimized it takes focus from whatever else I'm doing, like if I'm typing in Notepad when the program sends the message it takes the focus from notepad.

It can be just a hint if it's too much code for the whole thing. This is the assignment:
Quote:
This form will collect from the user their name and e-mail address. It will display for them what they entered and then ask them to be sure they entered the right name and e-mail address. If the user selects �yes‟ from the message box, the name and e-mail address will be added to the data file.

I have a datagridview that is binded to an database file. I also have a group of textboxes that are also binded to the same database. I wanted the user to add new inputs from the textbox to the datagridview. I tried using the code
Me.tableBindingSource.Addnew But instead of adding the new inputs into another row and column. It edits the input that is on the datagridview that is currently on focus before I can add new inputs.

I am trying to simulate human temperature taking. Basic i just need a button, a text box , a progress bar and a timer.What I want to do is that when the button is clicked, the progress bar will slowly increment and after it reaches maximum, a random number in the range 35-40 will be generated in the text box.Now so far, this is what I`ve done:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Timer1.Start()
Dim r As New Random
[code]....
So the progress bar is working fine. The random number generator too. But here are my problems:
1-Once the button is click, the number is generated. I would like that to happen after the progress bar reaches maximum.
2-So this is suppose to be a temperature gadget for kids and therefore when a certain amount of temperature is reached...an alarm is sent to the parents. How do I generate a dialog box (to acknowledge an alarm was sent) in case the temperature exceeds say 38? The dialog box should close after some 5 seconds. If possible, in case of such excess, the button color should turn to red or otherwise(no excess) blue.

I got a table related to another table by orderref. I need to know what should be my SQL adapter command if I need to take some information from one table and some from another where orderref = "" or should I be making two separate SQLs?
I used to have this when I had only one table:
myStr = "select * from orders where Orderref='" + txtorderref.Text + "'"
Dim sqldaHistory As New SqlDataAdapter(myStr, nwindconn)
sqldaHistory.Fill(myDataset, "orders")

With my datagridview I have column for datetime. I used the following for format.
Mydatagrid1.Columns(3).DefaultCellStyle.Format = "dd/MM/yyyy"
But the problem is it's getting input like MM/dd/yyyy and after pressing enter it's changing to dd/mm/yyyy style. So is it possible to read input like "dd/MM/yyyy".

My program has an access database with a table called "Contacts". This table stores many values. I have a seperate table that stores surveys. Each contact should have a column for every survey, indicating whether or not the survey has been completed. However, this means I need to add columns to the database while the program is running. I tried the following code, which runs WITHOUT errors, but does not seem to actually add the column.
contactsDataAdapter = New OleDb.OleDbDataAdapter("SELECT * FROM Contacts", frmAdmin.con)
contactsCommandBuilder = New OleDb.OleDbCommandBuilder(contactsDataAdapter)
dtContacts.Clear()
