View 3 RepliesI'm creating an application that allows the user to create their own queries based on criteria in various list boxes and my idea was to produce the results of the SQL in a "new" DGV, which in turn will be created in a "new" TabPage in a separate form . Each time the user runs a query a new DGV and TabPage is created. I've named each "new" DGV based on a user textbox so each "new" DGV will be named differently. The problem is how do I reference each new DGV? At the moment I get-"the value of type 'Syst.cannot be converted to string"It allows me to name the DGV with a string, but not reference it!
Any ideas how I reference a DGV when its created in runtime.

In VBA from Access 2003 I was able to employ the following :Form.Controls(" in here I am able to use a string variable holding the name of the control I want to reference ").property= etc.Is this kind of thing possible in VB .netI have a listview control to which I am adding 'errors' and the tag property of each item hold a string that is the name of the control I want to set the focus to when they double click on the listview item. So I want to do something like this :<listviewitem.tag>.focus()and have the string interpreted as a control name.
View 5 RepliesI am using this:
Dim oFile As System.IO.File
Dim oWrite As System.IO.StreamWriter
oWrite = oFile.CreateText("e: est.txt")

oWrite.Close()
Which works, but I would like to have it so instead of creating test.txt it names the document using multiple input text instance.

What VB.NET or C# coding standards are you using for your .NET applications?I was looking at hungarian notation and I don't think it is a good idea for a .NET application.
I have the following controller actions:
<HttpGet()>
Function News() As ActionResult
End Function
<HttpGet()>
Function News(ByVal id As Integer) As ActionResult
End Function
I want it to be smart, and go to the first if I have no ID in the url, and the second if there is. I got the following error:
The current request for action 'News' on controller type 'MarketsController' is ambiguous >between the following action methods:
System.Web.Mvc.ActionResult News() on type TradeChaseMVC.MarketsController
System.Web.Mvc.ActionResult News(Int32) on type TradeChaseMVC.MarketsController
So, I thought if i explicitly created routes without the id parameter optional, like this:
routes.MapRoute( _
"Default2", _
"{controller}/{action}/{id}",
New With {.controller = "Home", .action = "Index"},
New With {.action = "^[a-zA-Z_]+$", .id = "d{1,8}|"}
[Code] .....
It would work, but it doesn't same error. Now I know the simple solution is to call my methods different things, but i don't want to do this. I was also thinking of creating an attribute to prefix the ID method, to check for ID being there, and if it isn't dont allow that method, but I can't get this to work either.
I'm having the exciting task of finding out about VB.NET's <> and Not operators. Not - I'm assuming by my small use of it - is the functional equivalent of ! in languages such as C# and <> being equivalent of !=.
In VB.NET a common problem is doing Boolean expressions against objects that don't have a reference, it appears. So if we do If Request.QueryString("MyQueryString") <> Nothing Then This will actually fail if the query string doesn't exist. Why, I don't know. The way that it's done by older coders is as follows: If Not Request.QueryString("MyQueryString") Is Nothing Then
And this tends to work. To me they're functionally equivalent though operators tend to do different comparisons dependent on certain factors such as operator precedence, why it doesn't work in this case however, I do not know, and neither have I found any relevant material. I ask this as I'm having to write standards documentation and we're determining the use of either the Not or <>.

View 1 RepliesI've created a VB.NET2010 stub service application with a bunch of common features that I'd like to be able to use repeatedly as the starting point for various more specialized projects.
For each spin-off project I want to be able to start with the stub and then rename the service "completely", so that each instance behaves as if it was created from scratch with its own unique name.
I've tried the steps below with limited success; the re-named service builds as wanted/needed, BUT it won't run because I can't add the new service name to the StartupObject pulldown list.
Change ServiceInstaller.ServiceName from stubName to newSvceName.

Mostly because of reading this site, I'm trying to move away from Hungarian Notation. Or I guess the improper (system) Hungarian.
I can figure out a better way to name most data types, but I don't know what to do with objects. What would be a good naming convention for objects? I use objRS for recordsets now.

View 3 RepliesI wish to be able to instantiate my Cell class while naming the cell instance with such name as "A", "B", "C", etc. just like in an Excel spreadsheet.

NativeCell = nativeCell;

I would need to generate a name based on the alphabetic letters and double and triple them once I encounter the last alphabet letter 'Z'. The algorithm would have to generate the letters that I would concatenate with the rowIndex value that would result to this naming strategy such as Excel.
The letters would be:
A, B, C, D...Z, AA, AB, AC...AZ, BA, BB, BC...BZ, CA...XAA, XAB, XAC...
While we clearly know that colIndex value 1 will definitely designate column "A", value 2 = "B", value 3 = "C", etc.
My problem is particularly when we double the letters.
how I could achieve this in the simplest possible form?

I am generally not one to engage in subjective arguments over matters like variable naming, code formatting, etc. So I have no intention of starting an argument here.I just came across this (old) blog post which recommends not prefixing member variable names:
[Code]...
I get it: member variables can be lower camelCase, and public properties/methods can be PascalCase. But VB.NET is case-insensitive, so you can't really give a private member the same name as a public property except with a lower case first letter.I've generally prefixed member variables with an underscore, but I've been told that's not idiomatic.
So really I'm just curious: how do you name your member variables in VB.NET? And is there a "standard" way?
I'm not asking because I believe there's a "right" way or because I particularly want to change my style, and certainly not because I have any desire to tell others they're "wrong." Like I said, I'm just curious.
In the code below, the namespace is called "Navigation" which I think is correct. Then I have a class called "Heading", which by definition is the direction a person/vehicle is truly pointing towards. I think that is also named correctly. In the code below, I have four things I have named:
_WhatToName1, WhatToName2, WhatToName3, and WhatToName4.
The value that gets passed in and stored is a double between 0 and 360 -- essentially the degree value from a circle. For WhatToName3 and WhatToName4, I have seen a lot of places that just use "value" as the name. Is that standard?
Namespace Navigation
Public Class Heading
Private _WhatToName1 As Double
Public Sub New(ByVal WhatToName3 As Double)
Me.WhatToName2 = WhatToName3

I have experienced this in both VB 2005 and 2008. First, design a form by placing your UI elements where you want them. Then, go back and start naming your controls the way you want them (i.e. "txtWhatever" instead of the default "TextBox1", etc.).I find that after you change the name of a control, there is a slight but annoying delay as VS IDE digests the fact that you changed the name, thus slowing down my workflow. I recall that this process was much more rapid-fire in the VB6 days - i.e. name one control, click the next one and start typing, boom-boom-boom.
Has this annoyed anyone else, and if so, have you found any kind of remedy to speed things up in this regard?
What is the most commonly used convention (in C# and VB) to name object, when I want to emphesize that it is an instance of class that implements some interface. Like here:
//is iDisp correct name?

iDisp.Dispose();
Console.WriteLine("Disposed");
}
I'm relatively new to .NET and am wondering how people handle naming their private variables and the public properties that access them. Like if you want to be able to just read it, but not write to it.
[Code]...
So far I've taken to putting a 'l' (for local) in front of the all the private variables so as to be able to use the full name for the property. Is there a better way around this, or do you just always have to have different names for private variable/public properties? If so, what sort of conventions do people use?
Its not a huge deal, its just a minor annoyance and I was wondering if I was missing something.
