Error - Conversion From String "" To Type 'Integer' Is Not Valid

Aug 25, 2009

Basically I am trying to have it so when they click the save button it changes the timer.interval to what they entered in the textbox.On form load I have it do this.

Timer2.Interval = My.Settings.timer_interval
timertxt.Text = Timer2.Interval / 1000

When they click the save button.

My.Settings.timer_interval = timertxt.Text * 1000
Timer2.Interval = My.Settings.timer_interval

The program works, but it throws an error Conversion from string "" to type 'Integer' is not valid.I understand that the textbox is a string and the Timer Interval is a Integer, make it work without having to click continue after it throws the error.

Conversion From String To Type Integer Is Not Valid

I have the below code in my app... Nothing is declared as a integer so I dont understand or see where the problem could be... It is saying:

Conversion from string "9838 Co Rd 47" to type 'Integer' is not valid.

The address is flowing through the entire function as a string the only place I think it could be getting changed somehow is in a function call... Below is the function that throws the exception. Followed by the function that returns the address.[code]...

Conversion From Type String To Integer Is Not Valid

Public Class Form1
Private Sub RealTime_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RealTime.Tick
Real_Sec.Text = DateAndTime.Now.Second
End Sub
Private Sub Real_Sec_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Real_Sec.TextChanged
Sim_Sec.Text = Sim_Sec.Text + 1
If Sim_Sec.Text > 59 Then
Sim_Sec.Text = 0
End If
End Sub
End Class

When the timer is on, it will tell the current seconds in real time, and when the text in the textbox for the Real_Sec changes, it will increment the text or the value in the Simulated seconds... FROM 0... No matter where the seconds are in the real seconds, it will display real or simulated seconds in the sim_sec text box... Starting from 0... But there Real Seconds, because the Timer is not accurate. So I Simulate the Real Seconds. How to write it the right way, it's keeps throwing the error:
An error occurred creating the form. See Exception.InnerException for details. The error is: Conversion from string "" to type 'Double' is not valid.

Show Textbox Input In MsgBox Error! Conversion From String "Tabii" To Type 'Integer' Is Not Valid?

Feb 19, 2012

The project I'm working on is a Multichoice RadioButton quiz with answers and percentintegers. At the end there is a MsgBox that gives the number of answers counted 'correct'and the percent 'correct'. Also after you press the confirm button on that MsgBox it emails the results to the built in information given on the SMTP information. What I am trying to do now is show the input typed into the textbox on FormA in the MsgBox at the very end.

Conversion From String YyyyMMdd To Type Integer Is Not Valid

Oct 2, 2009

I have a dataset containing a datatable, and I enumerate all rows in that datatable. When trying to format a column in that row, I run into an exception. (Part of) the code is:

For Each dr As DataRow In ds.Tables("records").Rows
file = dr("timestamp").ToString("yyyyMMdd") & "~.wav"
Next

This results in the following error message:

Conversion from string yyyyMMdd to type Integer is not valid. (translated from a Dutch error message to the English equivalent)

dr("timestamp").GetType.FullName results in "System.DateTime", so I don't understand why I run into this exception, as for example Now.ToString("yyyyMMdd") results in "20091002", and "Now" is of the same type as dr("timestamp"), "System.DateTime" that is.

VS 2008 - Conversion From String To Type Integer Not Valid

I am working on a program that has a combobox that gives you selections for email address endings, but when I try to enter it in as part of the final email address get an error. Here is my
mail.To.Add(TextBox1.Text(ComboBox1.Text))

When I click debug, it give me this error. "Conversion from string "@txt.att.net" to type 'Integer' is not valid."
"@txt.att.net" is the value of the combobox selection.
In the end it should be something like: "anything@txt.att.net"
(Textbox1.text = "Anything" & the current ComboBox1.text selection = "@txt.att.net")

Error: Microsoft.VisualBasic: Conversion From Type 'DataRowView' To Type 'String' Is Not Valid

I now have SQL Parameters set up and I'm using them to save/delete/add my data. This all works well, except when it's trying to save a combobox to the datatable it appears with the error above.Majority of my comboboxes have datasources, and the valuemembers of these are the actual list items, not the ID's of the list items.I'm not sure why this error could be happening, I'm fairly sure I've connected everything to the binding source correctly; I've checked it a few times.Does anybody know what the cause of this could be? I've looked around a bit and I haven't found much

I am getting the error "Conversion from type 'DataGridViewTextBoxCell' to type 'String' is not valid." When trying to display a cell from DGV in a listbox.I have my variable for the cell reference as follows:

Dim a As Object

lstLetter.Items.Add(a)

This will not actually display the entry inside the referenced cell, it shows this in my listbox instead:

DataGridView TextBoxCell { ColumnIndex=4, RowIndex=1 }

how I need to convert this to display.

Jun 25, 2011

I wanna perform a function like this. When you save a record, I need the primary key of that record to be auto-generated (X001). Say, when you create a new record and save it, it should be saved like X002 automatically.So to test this before I implement that on this project I'm working on, I created this little program.form.png

All its supposed to do is, when you click on the OK button it shows a code that is fetched from a database table. (X001). Then when you click on it ober and over again. The number should increase. X002, X003, X004... so on.Here's my code
