Python Use In VB .Net As Compared To Excel?
May 1, 2012
I have an interesting issue I've run into where I can easily tap into python code from VB in an excel instance, as described here: Calling python script from excel/vba.However, when I mimic the exact same code structure in visual studio in a form, the pyscript.language = "python" line fails. Does anyone know if MSScriptControl.ScriptControl can be used in VB .Net to control python like you can in excel? This would be a lot easier than setting up a com object for my python scripts.
Example code (need to add microsoft script control 1.0 and excel object library):

In VB.NET projects, errors are highlighted immediately after cursor leaves the line. In C#, I have to wait several seconds for IntelliSense to highlight it. Also, the C# version doesn't show all project errors in "Errors List", unless you start to build it. Actually, it seems to work differently in every way. Is it possible to adjust that behavior?
I am using both Visual Studio 2008 and Visual Studio 2010.

Yesterday I was at an interview where my interviewer (who admittedly didn't claim to be an expert on the subject) stated that "VB.NET is more weakly typed then C#" - (At the same time he couldn't recall an example). This statement seemed incorrect to me (particularly given that both languages use the same framework libraries for their types) and I advised as such and that perhaps he was confused with the option to turn Option Strict or Option Infer on/off.
At the same time I know that VB.NET has situations where it will do type coercion - leading to occasionally unexpected results (although I also cant recall under what conditions) - (Actually I think I just remembered that it was mainly when performing arithmetic operations with different types - whereas other languages will force you to be explicit (?) ).

I've been developing databases for research using ms access for the last few years. The application is used on accross a hospital network and while it was slow initially, itstarting to come to a grinding halt as numerous users are accessing it at once. I've been debating whether to try and develop the front end using vb.net in hopes of making the application faster.Does anyone know if this would be the case?

However, for several years now, I have been working primarily in the .Net space. Initially, my transition into the .Net world consisted of writing and maintaining VB.Net code. VS provided almost all of the nice intellisense support I came to expect after years of working with the Eclipse/Java combo. Eventually my employer decided to do new development in C#. My initial impression of the intellisense support for C# was less than stellar. At times it seems as if VS has no background compiler for C#, but occasionally it does something smart, indicating there is some background processing there, but not quite enough to really boost productivity in meaningful ways. Is there any sane technical reason for this discrepancy regarding intellisense support between the two languages?

I need to write software that will do a lot of math. Mostly it will be matrix multiplication with integers to compute DCT. How much faster should I expect the code to run in native c as compared to VB .Net? Factor of 2, factor of 10, factor of 1000...?

I am working on a large project with hundreds of dll's being used on the same machine, on the real large windows there is latency issues that I would love to address. The VB6 project was quick and effective but dotnet is bulky and slow compared to vb6 version, what changes from vb6 to dotnet would increase performance and reduce latency in the larger windows?
Working with VB08 3.5 Framework so parallel isn't going to work sadly, what other methods are there from a code standpoint could I use? DUring the conversion process could it be using parts of code that bog the system down?

Is it possible to create a class in VB.NET that can be compared to a string in a switch statement? For example, let's say I have a class Foo:
Public Class Foo
Public Bar As String = "test"
End Class
Is it possible to implement some interface or override some equality operator so that I could use Foo like so?
Dim foo As New Foo()
Select Case "test"
Case foo
' It worked!
End Select

I am using VB.NET and I can't compare the radio button lists selectedItem.Value to a string, it doesn't work...here is the code: (I have also tried selectedValue it does not work either)
[Code]...
Why won't it evaluate that rblOne.SelectedItem.Value = "No" !?!?!? I tried rblOne.SelectedValue, that doesn't work, AND I added .ToString to both, which did not help, I even tried it w/ "No".ToString...this doesn't make any sense.

I have a program that someone else designed the form on and sent to me to populate the code. I am not sure what could have been done to cause this problem, hoping for a quick oversight on my part. There are several fields of textboxes that the user enters numbers in. Normal behavior for textboxes is when you tab to them the current contents are highlighted. On one of these textbox fields, and only that one set of textboxes, the contents are highlighted like normal at first, but after the user edits the content of the textbox, if you tab to it again it will go directly into edit mode instead of highlighting the contents. Each textbox in the field does this individually, so if you just edit one, all the rest will continue to highlight contents until you edit them as well. It appears you don't actually have to change the value of the textbox, just entering edit mode and getting a blinking cursor is enough. I cannot find a difference in the properties of these textboxes compared to the rest.

I have a function in vb that is converted to a dll that I want to use in python. However trying to use it, I get an error message this is the VB function

print test.DISPLAYNAME("one")
But I get errors so what is the right way of calling the dll
Traceback (most recent call last):
File "C:Test estdll.py", line 4, in <module>

I have always wondered about this and seen this among lots of programmers. Why is a VB programmer or VB code easily dismissed as too noobish and easy while the same does not apply to Python or Python code? After all, isn't Python as easy as VB is? And it does provide drag-n-drop GUI application building also. So why is it that VB is flamed and yet Python is not?

I want to create a (3n*7) Matrix in python through Iteration, I did this in VB.Net and it worked but it gives me some challenge in Python as this a new language to me. n can be the number of Iterations to build up the matrix, i.e. ; if u iterated 3 times, the matrix will be a 9*7 matrix. Here is how I did it in VB.Net. :

I'm writing a python plugin for a geo referencing program called QGIS where I want an Excel sheet to do all my calculations for me. For different data points I need to set certain input values into the spreadsheet (which was already written by someone else). I'm fine setting the int values (using win32com.client) with
sheet.Cells(row, col).Value = value
For radio buttons I would expect it to work like so:
sheet.opt_name.Value = True
But I get the error message:
AttributeError: '<win32com.gen_py.Microsoft Excel 12.0 Object Library._Worksheet instance at 0x232878608>' object has no attribute 'opt_name'
What are the options attributes of? How do I set their values?

It is possible to do this in Visual Basic with .DLL classes?

I never thought I'd say this, but I am getting pissed at how easy it is to just plop down a variable in python without any declaration. I have an existing python script which interfaces with a server, and it builds its own messages to be communicated via sockets. What I am trying to do is take the command line python script and convert it into a VB GUI app that is more user friendly.

I am trying to run a python script inside a vb.net application, which means executing the code inside vb.net instead of runing it external. The problem is:
I am using MsScriptControl and set the language to "python", I tried to run it and get the error "A script engine for the specified language can not be created". My research has told me i need these keys in my registry. The problem is I cant find them so how to I make them. Or even better a full solution to my problem.
