Error: Option Strict On Disallows Operands Of Type Object For Operator '='. Use The 'Is' Operator To Test For Object Identity
Jan 27, 2010I am tightening up my coding with the Option Strict set to ON. It has now produced alot of errors. An example of this is:
If AllocatedDGV.Rows(i).Cells("RoomNumber").Value = RoomsAvailableDGV.Rows(j).Cells("RoomName").Value Then
It gives me the following error: Option Strict On disallows operands of type Object for operator '='. Use the 'Is' operator to test for object identity.
Option Strict On Disallows Operands Of Type Object For Operator Use The 'Is' Operator To Test For Object Identity
Apr 6, 2012I need to write an interface to get data to/from our data files.
We have a low level class that holds field values for each record read from the files.
This just holds two values, the value read from the file (DBValue) and the updated value that may need to be written back to the file (CurrentValue).
These values may be any of the standard value types (integer, date etc) or a string.
Either value (DBValue or CurrentValue) may be null if not defined.
I have written the class to manage this data which works fine while option strict is NOT on.
But we have an office policy of having option strict on all the time.
When I put option strict on, my object value comparisons fail with the error: "Option Strict On disallows operands of type Object for operator '='. Use the 'Is' operator to test for object identity."
Question, how should I change the following code to handle option strict on ...
This is all running on Visual Studio 2010

View 7 RepliesVS 2005 Getting The Correct Number Of Attributes To Match The Correct Number Of Text Boxes?
Apr 18, 2009I have created a basic query generator which allows a user to select the Select, WHERE and criteria attributes using a number of checkboxes.However i have got stuck. In the results form i have the following code
Private Sub DisplayRecord()
RichTextBox1.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(0)
RichTextBox2.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(1)
RichTextBox3.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(2)
[code]....
The program keeps on crashing if the user does not select the corresponding amount of display records from above for the amount of attributes they want for the SELECT part of the query in the intreface in form 1.
How would i go about making something where the number of SELECT attributes selected which are listed in a string create the correct number of textbox fields in the results form (form2)

VS 2008 Checkboxes Not Showing Correct State?
Nov 5, 2009I have a form that has many checkboxes located on a tab control with 3 tabs each tab has checkboxes on it.I have a button that when pressed selects all the checkboxes. That does work and it does execute all that were selected. However there are no checkmarks appearing at all. This worked before! It seems like the more checkboxes I added to the form the less they properly showed f they were checked or unchecked. Now none of them show unless I close the form and reopen it then all of the boxes are checked like they should be when the select all button is pressed.

VS 2008 Input String Was Not In Correct Format?
Nov 15, 2009I am building a program for my CINS-113 class where it allows the user to enter a number 1-15 in a masked text box and then hit OK and it will display that number in a ListBox as such:
Say they enter 1...
1 X 1 = 1
1 X 2 = 2
1 X 3 = 3
...
1 X 12 = 12
I have gotten everything to work great, but when you enter anything but numbers 1-15 it properly provides a message popup telling you that your entry is basically not the right value, but then I get a build error that says "Input string was not in correct format" and it highlights my line: "intInput1 = Convert.ToInt32(strInput1)"

Problem #1: It does not send the keys fully correct all the time because its trying to send them all at once! So i want it to send them 1 letter after the other with 200 ms sleep in them! Problem #2: The sleep is not working: The reason i know is because even after it did the first textbox1 text it didnt wait that 2000 ms!
