convert string to int

Strings are converted automatically:

You can use IsNumber to make sure that the string can be parsed to a number:

Dear Erel.

If I use:
Socket1.Connect("10.100.100.103",123,5000)

it work's

but if I use
Socket1.Connect(strServer,intPort,5000)

It doesn't works, but strServer contains "10.100.100.103" and intport contains 123

See code down

Sub btnConnect_Click
Dim intPort As Int = txtPort.Text
Dim strServer As String
strServer = txtServerIp
Socket1.Initialize("Socket1")
Socket1.Connect(strServer,intPort,5000)
'Socket1.Connect("10.100.100.103",123,5000)
end sub

Please use [ code ] [ /code ] tags (without spaces) when posting code.

Check the values of intPort and strServer with the debugger. Make sure that there are no extra spaces.

By the way, a notice I have and hopefully I don't have to change thread. While quering an sqlite db, noticed that when requesting an int field, and the filed is null, I get a 0. Don't know if this is how it goes, but surely it would be nice for me to throw an error (so I can do other things with the null result). For now, my workaround is to request a string and check if it is 'null'.

@mc73: In order to avoid unwanted 0 in a SQLite table insert, update or query, I have started storing field type (data type) as TEXT even for numbers instead of INTEGER or REAL, except of course for a PRIMARY KEY. By doing so, you can still validate numbers before inserts and updates and you can insert an empty string without a 0 popping up when you query the data.

Dear all,
I found the problem.. very stupid I am :signOops: :sign0013:

4. strServer = txtServerIp.text
