Hi,
Appreciate being able to get any feedback. I'm somewhat new to ASP.NET using 3.5
Getting error after adding a new field to an existing sqlreader class. The error is supposedly pointing to a null value in a datalist. But if this one line is removed there is no problem for the entire ItemTemplate.
_var= reader["field"] != null ? (int)reader["field"] : 0;
The only other change to the sqlreader class is the new field's get set.
Thank you in advance

If your field2 contains null, Eval("field2") will be null so you'll get a null-ref while calling Equals on it. Simply swap the operands:
<%# "".Equals(Eval("field2")) ? "" : Eval("field3") + " " + Eval("field4") + " " + Eval("field 5") %>
Although I'd recommend comparing with null which is more readable and likely more correct.

How can I have my telegramBot send automatically messages in a group?
def handle_event(event):
#print(event)
global amount0In
global amount1Out
global amount1In
global amount0Out
amount0In = event['args']['amount0In']
amount1Out = event['args']['amount1Out']
amount1In = event['args']['amount1In']
amount0Out = event['args']['amount0Out']
if amount0In and amount1Out != 0:
print(f"Token Sold {amount0In /10**18}, and eth {amount1Out/10**18}")
buy()
else:
print(f"Token Bought {amount0Out /10**18}, and eth {amount1In/10**18}")
sell()
def buy(update,context):
buyMessage = f"Buy!!!!\n💴: {amount1In/10**18}\nToken Bought: {amount0Out /10**18} \n"
update.message.reply_text(buyMessage)
def sell(update, context):
sellMessage = f"Sell!!!!\n💴: {amount1In/10**18}\nToken Sold: {amount0Out /10**18} \n"
update.message.reply_text(sellMessage)
In case the IF statement is met I want to send a message to a telgram group, however I cant execute the update message this way, because I keep getting this error:
TypeError: buy() missing 2 required positional arguments: 'update' and 'context'
How can I fix this?
To send a message, all you need is an instance of telegram.Bot. Please have a look at the introduction to the API for more details.
The functions buy and sell look like callback functions for handler. Since you are apparently not using python-telegram-bots handler setup to handle the event, there is no sense in defining those functions to accept the update and context arguments.

I have a problem with a SQL query. The problem is with the IN ...., but I don't know how to correct it. This is the query:
SELECT *
FROM Reports, Games, Developers
WHERE Game = SpelID
AND Developer = IDDvl
AND Land IN[‘Japan’,‘USA’,‘UK’,‘Indië’,‘Duitsland’,‘Zweden’]
This is the error message:
An unhandled exception of type 'System.Data.OleDb.OleDbException'
occurred in System.Data.dll
In operator without () in query expression 'Game = SpelID AND Developer = IDDvl
AND Land IN [‘Japan’, ‘USA’, ‘UK’, ‘Indië’, ‘Duitsland’, ‘Zweden’]'.
dagoederen = New OleDb.OleDbDataAdapter("SELECT * FROM Reports , Games,
Developers WHERE Game = SpelID AND Developer = IDDvl AND Land IN (‘Japan’,
‘USA’, ‘UK’, ‘Indië’, ‘Duitsland’, ‘Zweden’)", connectie)
You need to replace [ ] with () after IN
Use right brackets and quotes:
SELECT *
FROM Reports , Games, Developers
WHERE Game = SpelID AND
Developer = IDDvl AND
Land IN ('Japan', 'USA', 'UK', 'Indië', 'Duitsland', 'Zweden')
replace with this code
Imports System.Data.OleDb
Public Class Form1
Private Sub cmdsql1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdsql1.Click
connectie.Open()
Dim dagoederen As Data.OleDb.OleDbDataAdapter
dagoederen = New OleDb.OleDbDataAdapter("SELECT * FROM Reports , Games, Developers WHERE Game = SpelID AND Developer = IDDvl AND Land IN (‘Japan’, ‘USA’, ‘UK’, ‘Indië’, ‘Duitsland’, ‘Zweden’)", connectie)
Dim dtgoederen As DataSet = New DataSet
dagoederen.Fill(dtgoederen, "Reports")
connectie.Close()
dggoederen.DataSource = dtgoederen.Tables("Reports")
End Sub
End Class
The answer is specified in the error provided" In operator without () in query expression". Replace the "[]" with "()" for the IN T-SQL

I using version 3.2. When a soap fault returns from a service I want log the error and force the Global Exception. I tried using
<test:component throwException="true" />. While it does force the Exception to execution it also genreates a ton of messages in my log (see below). I need to clean this up or find a better to force the execution of the exception.

looks like this code is compiled pre generics support,
An error occurred at line: 236 in the jsp file: /dashboard_new.jsp
Syntax error, parameterized types are only available if source level is 5.0
recompile the code with jdk >= 1.5 would be my guess or maybe the tomcat server is setup to use a jdk < 1.5
hope that helps
EDIT:
all of the errors apart from the one below seem to be a compiled version issue.
this one :
An error occurred at line: 338 in the jsp file: /dashboard_new.jsp
Incompatible conditional operand types String and int
335: out.println( "<td valign=\"top\">" + frameBean.getLatitude() + "</td>" );
336: out.println( "<td valign=\"top\">" + frameBean.getLongitude() + "</td>" );
seems to be trying to concatonate Strings and Integers. this should also work in later versions of java, i think.
