Error - Conversion From String "" To Type 'Integer' Is Not Valid
Aug 25, 2009Basically 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.

Oct 20, 2011I 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]...

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:

Conversion From String YyyyMMdd To Type Integer Is Not Valid
Oct 2, 2009I 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.

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
May 25, 2011I 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

Error : Conversion From Type 'DataGridViewTextBoxCell' To Type 'String' Is Not Valid
May 2, 2010I 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
a = DataGridView1(4,1)
To insert it in the listbox as follows:
lstLetter.Items.Add(String.Format(a))
I tried:
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.

Conversion From String "Fixed_Fan_Electric" To Type 'Integer' Is Not Valid?
May 26, 2009I am currently working on a school project that requires me to develop a quote system for a heating company. It needs to include Date/Time, Customers Name, Address and phone number which isn't a problem.It also needs to be able to select different heating options each with specified prices (using a combo box), the price also is affected by how big the house is (using radio buttons - big house or small house). It also has to generate an overall price including GST which is 10%.
I have come up with a design and some code, everything works fine for the first option, however, when i clear the form and then attempt to calculate another quote i get the "Conversion from string "Fixed_Fan_Electric" to type 'Integer' is not valid." The other problem i have is the first option in the combo box calculates correctly and after re-opening the form (to avoid the first issue) i select another option from the combo box, the program is unable to calculate a price for it and just leaves the label blank.
