Looking for a thorough Iron Python tutorial.

Yes, collect the coordinate values from your up/down control and then redraw the rectangle with the new values. You probably need to override the OnPaint method in order to do it properly.

My understanding of basic Python is pretty good, but my memory fails me on all available modules and so forth, but when I last used Python, we had no luxuries like the DLR. I'm now looking for some advanced, in-depth Python tutorials, and I thought it best to look for ones that concentrate on integration with .NET. All suggestions are most welcome.

Hehe, oops. Blush | :O

I somehow missed the "IronPython .NET Integration documentation" when I downloaded IronPython. It is more reference format though, but I should be quite fine walking myself through building something small.

How can i learn OOPS concepts in a easy way to get the grip over the subject and use it in my daily coding life.

Assuming that you mean OOP concepts (Oops is an exclamation), then you could start with https://www.google.co/search?q=OOP[^].

I know, hence my comment: it's OOP not OOPS. And did you follow the link I gave you?

Thanks Richard. I am getting an error while trying to opening the link it is showing error message as I am trying to open it from Google. Could you please suggest me another link so that it'd be grateful for me to learn.

aspx file: Operator '&' is not defined for string

Re: aspx file: Operator '&' is not defined for string

18-Mar-15 8:07

OK - I'm pulling my hair out trying to figure this out. I'm saving my file as an aspx file.

My error message is Operator '&' is not defined for string.

Here's my code:
*******************

dim sOutput1
dim sOutput2
dim sOutput3

strconnect = ("PROVIDER=Microsoft.Jet.OLEDB.4.0;DATA SOURCE=" & server.mappath(dbName))

dbconn = server.createobject("ADODB.connection")

dbconn.open(strconnect)

selAll = "SELECT * FROM PH_Stf_Dist2 ORDER BY dept, [last name] " 'sort by last name then first name

qresults = dbconn.execute(selAll)

sOutput1 = "<td> <input type='text' name=DEPT maxlength = '4' value="

sOutput2 = qresults("DEPT")

soutput3 = "></td>"
			
Response.write (sOutput1 & soutput2 & soutput3)

***************

I have broken it down so I could see exactly where the error occurs (soutput3). This worked in .asp; but .aspx is not working.. Confused | :confused:

Actual error page:

Operator '&' is not defined for string " ")
Line 102: Response.Write (" ")

Source File: E:\Websites\cwa\Intranet Home\PhoneDirectory\phone_directory.aspx Line: 100

Stack Trace:

Any help would be MUCH appreciated!

Your post is completely unreadable. Don't copy and paste the text from the web page. Copy and paste the actual code that threw the exception and put it inside PRE tags.

Response.write (sOutput1 + soutput2 + soutput3)

The original post ended up in 4 columns. When the formatting gets all weird compared to a standard post I cannot assume I have all the information intended. To you, it looks fine because you are the only person who saw the screen and you are the only person who knows what to expect in the copy'n'paste.

Other people who have not seen your screen do not know what to expect.

You don't show the definitions of the sOutput1, soutput2 or soutput3 so assumptions have to be made.

If your code snippet was a copy'n'paste job, not typed by hand, try it this way

Response.Write(String.Concat(sOutput1, soutput2, soutput3))

nope.. same message with the '+' instead of the '&' (but thank you for the suggestion!)

You're still using ADODB in a .NET application; you should look at switching to ADO.NET[^] instead, which has much better support.

Using ADO.NET for beginners[^]
Migrating from ADO to ADO.NET[^]

The problem is most likely that ADO is returning an ADODB.Field object, which can't be used with string concatenation. If I remember correctly, you need to access the field's Value property, and convert that value to a string:

VB.NET

sOutput2 = Convert.ToString(qresults("DEPT").Value)

You should also specify the types of your variables when you declare them:

VB.NET

Dim sOutput1 As String
Dim sOutput2 As String
Dim sOutput3 As String
