Input String Not in Correct Format

[tjonsek]

I'm building a string to be used as the body of an email.

I'm getting this error message. "Input String Not In Correct Format".

I've checked several newsgroups, however, for the posts I found it was
always in conjunction with a query or conversion. This is neither.
It could be the control break I'm trying to use. I also tried
researching that but came up with a bunch of posts for web/window
controls that are breaking, rather than something to do with display of
text.

Here is the line of code that seems to be causing issues.
body = "The following payout is requested " &
Me.ddlType.SelectedValue.ToString & ": " & g_key & ". " & vbCrLf & _

Polite input is very welcome.
Thanks

always in conjunction with a query or conversion. This is neither.

That depends, conversion is possibly occuring. What data type is the
variable "g_key"? What is "body" -- the MailMessage.Body property or your own
variable? If it's your own variable what is it's data type?

Try the following:

body = "The following payout is requested " & Me.ddlType.SelectedValue & ":
" & Convert.ToString(g_key) & ". " & vbCrLf

Changes:
* Removed the .ToString() call on Me.ddlType.SelectedValue since
..SelectedValue is already a string
* Added an explicit convertion to string for g_key since it's data type is
not specified here.
* Remove the trailing ampersand and underscore (& _) after the visual basic
constant vbCrLf.

I made the changes you suggested. Here is the full code for that
string. It's still bombing out on that line.
Not quite sure why.
body = "The following payout is requested " & Me.ddlType.SelectedValue
& ": " & Convert.ToString(g_key) & ". " & vbCrLf & _
body = body & "Date Prepared: " & Now() & vbCrLf & _
body = body & "Date of Incident: " & Me.txtDtStart.Text &
vbCrLf & _
body = body & "Union: " & ddlUnion.SelectedValue & vbCrLf & _
body = body & "Reason: " & Me.ddlType.SelectedValue & vbCrLf &
"For the following employee(s):" & vbCrLf & vbCrLf

I split up the commands to build the string to make it easier to read
and debug.

Oh, and g_key is an integer.

Ok. I did notice that my line with

body = body & "Date Prepared: " & Now()

was causing a conversion error as well, so I changed that to: body =
body & "Date Prepared: " & Convert.ToString(Now() )

I'm still getting an error, however the stack trace has changed. I
dont' understand the error message "[InvalidCastException: Cast from
string "Date of Incident: 12/12/05" to type 'Boolean' is not valid.] ".
I don't know how this could be happening. This is the line references
'Date of Incident':

body = body & "Date of Incident: " & Me.txtDtStart.Text & vbCrLf & _

Here is the complete stack trace as I see it on the browser when
testing:

Thanks!

Never mind. I made a dumb error and did not remove the '& _' when I
changed how I built the string.

Maybe try making use of StringBuilder Class.
It would make life much more easier

Like Patrick said, it's much more readable if you use a string builder. I'll
give it to you both ways:

body = "The following payout is requested " & _
Me.ddlType.SelectedValue & ": " & _
Convert.ToString(g_key) & ". " & vbCrLf & _
"Date Prepared: " & Now().ToShortDateString & vbCrLf & _
"Date of Incident: " & Me.txtDtStart.Text & vbCrLf & _
"Union: " & Me.ddlUnion.SelectedValue & vbCrLf & _
"Reason: " & Me.ddlType.SelectedValue & vbCrLf & _
"For the following employee(s):" & vbCrLf & vbCrLf

With a string builder:

Dim sb As New System.Text.StringBuilder
With sb
.Append("The following payout is requested ")
.Append(Me.ddlType.SelectedValue)
.Append(": ")
.Append(Convert.ToString(g_key))
.Append(". ")
.Append(vbCrLf)
.Append("Date Prepared: ")
.Append(Now().ToShortDateString)
.Append(vbCrLf)
.Append("Date of Incident: ")
.Append(Me.txtDtStart.Text)
.Append(vbCrLf)
.Append("Union: ")
.Append(Me.ddlUnion.SelectedValue)
.Append(vbCrLf)
.Append("Reason: ")
.Append(Me.ddlType.SelectedValue)
.Append(vbCrLf)
.Append("For the following employee(s):")
.Append(vbCrLf)
.Append(vbCrLf)
End With
MailMessage.Body = sb.ToString()
