Determine Which String: "Input String Was Not In A Correct Format"
May 14, 2009
I am receiving this error message: "Input string was not in a correct format." on my ASP.net 2.0 VB project.
When looking at other posts with this error its obvious that each time it will be specific to the users' project. Therefore my main question is, is it possible to generate a more informative error message?
I am already in debug mode but it does not tell me in which string the problem lies. I am converting some strings to integers with "Cint" and have also tried the Integer.Parse() method to no avail.

I'm having an issue with a page I created that was working fine two months ago. Nothing has changed in structure of the SQL tables and I have even done an insert within SQL to the table and all works fine with SQL. So the problem lies within the code. I'm getting this error:
Input string was not in a correct format.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.FormatException: Input string was not in a correct format.
Source Error:
Line 71: Dim sv As String = grd.Rows(i).Cells(7).Text
Line 72: ApproveManifest(sv, ffisID)
Line 73: Insert(sv.Remove(0, 6))
Line 74: PushIn001(sv.Remove(0, 6))
Line 75: PushIn002(sv.Remove(0, 6))
[Code] .....
If I comment out line 73 and run it, I get the same error on 74. If I comment out 73, 74 and 75 the code runs to the end fine, it just doesn't insert the data into my table. It was working just fine and now it's not working.

Making a currency conversion program and I'm trying to run this code and I get an error saying that "Format exception unhandled: Input String is not in correct format". Then it points me to the line decUSDollars = Convert.ToInt32(strUSDollars) under Private Sub btnConvertButton_Click. I've looked all in my textbook and I can't figure it out.

My error message is as listed in the header "Input string was not in a correct format" however the stack trace is even more cryptic [code]...
This is worse due to the fact that nowhere in the project does it use "ParseDouble". I believe that this has something to do with the objectfactorylibrary but can't pin anything down.

With the following snippet
Foo = IIf(String.IsNullOrEmpty(txtFoo.Text), 0, Integer.Parse(txtFoo.Text.Trim))
I get the error when I submit the field without a value: "Input string was not in a correct format." I don't have any space or something else and String.IsNullOrEmpty(txtFoo.Text) returns true.

I am having some trouble with a DataBound TextBox with the Decimal DataType.
Here is the situation:
- I have a TextBox bound to a column in DataTable in a strongly typed DataSet.
- I have an ErrorProvider that has the BindingSource set to the same binding source as the TextBox.
- The Datatype of the column bound to the textbox is Decimal.
- I have my business rules set up as Partial Classes in the Dataset.
- I am capturing the ColumnChanged event in the Partial Class for the DataTable in question.
The issues are:
- The ColumnChanged event fires in all cases except when there is a data constraint. For example you enter non-numeric values in the TextBox.
- Once you violate a data constraint you cannot leave the TextBox empty even though the column is nullable.
In the above scenario the error icon appears beside the TextBox with the error "input string was not in a correct format."
There seems to be an internal event triggering before my business rule logic is able to process.Desired functionalty:Bypass this internal event and present my own error message to the user using the business logic coded in the partial class.

I have a dropdown list which extracts data from my SQL database and gives the users two options to choose from (Weekly / Monthly). The database has an ID for each of these. Weekly is set to 1 and Monthly is set to 2. This drop down is linked to a gridview which extracts / displays the data based on the selected item. All of this works perfectly fine. This issue I have is that I want to add some code in my Page_ load event to populate a text box with the selected item. I would also like to set the dropdownlist as default to weekly when a users access thie page. I thought that the two following bits of code would work but I get the message 'Input string was not in a correct format'.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
'This works fine
lblTodaysDate.Text = GetDate()
'I thought I could complete an If Statement to get the text box to work.
If DropDownList1.SelectedValue = 1 Then
txtMeeting.Text = "SMC Weekly Meeting"
Else
txtMeeting.Text = "SMC Monthly Meeting"
End If
End Sub
I am new to .net but have read that I might need to convert my int to a string?

I keep getting the following error: "Input String was not in correct format" and it relates to the following line of objRow1 = objDataSet.Tables("tblStudent").Rows.Find(selA) I cannot grasp why this error keeps occuring. I have definately used this format (i.e. datarow = dataset.tables("tablename").rows.find(something)) elsewhere and have had no problems.
What I'm doing is reading the values in a listbox and trying to find their related IDs. The values in the list box are names from one particular table in a database and I need to get their IDs to save to a second table.

Within a project of mine I have created a group box that I am using to convert an input temperature from Celsius to Fahrenheit with the click of a button. The input is a text box value, manually entered. However, VB is giving me an error when I try to parse the string input of the text box so that I can convert the temperature values. I want the temperature to be converted for any values entered into the input box. Here is the code I am using...
Private Sub Button9_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button9.Click
TempC = Double.Parse(Text3.Text)
TempF = Double.Parse(Text4.Text)
[code].....
The error tells me that "the input string was not in a correct format"
The code works when I replace the input strings with an actual string, but again, I want the user to simply type in a value to the temperature box, hit convert, and then receive the conversions.

But when it executes, I always get a FormatException:

What could be causing this?i am sending value like this.

When I attempt to read my Xml file when using a schema file I get the following error message:
Input string was not in a correct format.
If I delete the schema it read its fine so I am assuming something in schema file isn't matching the incoming data? How can I determine which line is creating the error?

I 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)"

I keep receiving this same error about 3-4 times a day and have had no luck tracking down how to resolve this issue. According to the stack trace, the error is occurring within the Microsoft.VisualBasic library so how exactly would I go about fixing this issue? Here's the report I send to myself and what gets generated by the server. Any suggestions would be greatly appreciated.
[Code]...
Update: I understand what the error is and what would cause the error to occur. The problem I'm running into is finding out where exactly this error is coming from within code. The stack trace tells me its coming from Visual Basic but there's nothing else. No line numbers, no other info about what function caused this error to occur, there's zilch to go on so I'm left scratching my head trying to diagnose something, that looks to be wrapped up in a .dll probably.
We're running Ektron 7.6.6 sp2 if that sheds any light onto the subject. Is there any way to get a more robust stack trace? I checked the event viewer on the server and the info i posted earlier is all that's displayed in the event viewer. Which is none to helpful.

I am just learning VB. My problem is the following "Input string was not in a correct format."
Dim fmtStr As String = "{0,-12} {1,10:C2) {2,7:C2}"
lstDisplay.Items.Add(String.Format(fmtStr, "Item", "Quantity", "Price"))
lstDisplay.Items.Add(String.Format(fmtStr, "pizza slices", QP, Pizza))
I get the above message or one that states the following: "Index (zero based) must be greater than or equal to zero and less than the size of the argument list." My teacher is of no help, she tells me to submit the project and she will tell me then. I have submitted a project with the same problem and she told me it worked. I know it didn't. Can someone explain what these messages mean ?

I have some code in a VB module. When I run this with the SQL statement having hard coded values in the where statement it works. I am now trying to add Parameters to the module so that the Form can except an Input from a user, but I am getting the message: Input string was not in a correct format.
Here is the section of code:
objCon.Open()
objCmd.Connection = objCon
objCmd.CommandType = CommandType.Text
objCmd.CommandText = sSQL

Like I said, if I substitute the Parameters for fixed values it all works.

I have the following function for generating sha512 hashs. The hash is generated successfully, but is causing this error when the resulting string is passed to other functions:
Input string was not in a correct format
When debugged the variable holding the returned hash (set as string) is empty. I have tried changing the type to int, int64 and byte (array and standard variable) in the function and in the calling code, which causes various other errors. How can I change the datatype correctly to solve this?
Function create_hash(ByVal password, ByVal salt)
Dim salty As String = password & salt
'convert salty password to binary to feed into hash function
Dim encText As New System.Text.UTF8Encoding()
Dim btText() As Byte
[Code] .....
Calling code:
Dim i_h_pass As String
Dim i_pass As String = pass.Text
'handle password generation (matching passwords checked at validation)
Dim newHash = New hashing
Dim salt As String = Convert.ToString(newHash.create_salt)
i_h_pass = Convert.ToString(newHash.create_hash(i_pass, salt))
The create_salt function has also been checked - it works perfectly and returns a random integer, returned as string for convenience.

I have a user that is receiving the following error: "Input string was not in the correct format"So I looked into the code and I can see why he is getting the error. The code is trying to execute this line:
_MyObject.LineBreaks = "0"
And the property looks like this:
Public Property LineBreaks() As Integer
Get
Return _MyLineBreaks
[code]....
Now, I immediately see that this old code is trying to set a string into an Integer and the old programmer was not using Option Strict, so he didn't notice this, BUT the problem has only happened one 1 user's PC. Running from the IDE works fine as well as installing the application other PCs. The code is executed every time the application runs, but yet only one person has reported the issue.Why would one PC baulk at this, but not the VS IDE or any other PC so far? Is there some system setting that determines how type conversion is handled? I need to get this user up and running.

I have a DGV with a column bound to a Double. When I enter "1%" I get:
System.FormatException: Input string was not in a correct format.
I then try: MsgBox(System.Double.Parse("1%")) and get essentially the same error. (same for "$")
Is there a setting that will allow "$" & "%" as not only valid Double input but also do the correct adjustment for "%"?
