Why Not Use Underscore (as Opposed To CamelCasing Etc) In Function_names

Apr 4, 2012

Is there any good reason not to name functions with underscores in them? I'm aware of using a leading underscore for private members etc. but why not have functions like do_this_work()?

VS 02/03 Underscore In Folder Name?

May 3, 2009

The code below works fine on Windows XP but raises "InvalidCharacter in path" exception on Windows 2003. It works on Windows 2003 when I remove the underscore from the foldername. I don't have a Windows 2003 machine at hand right now so I was wondering whether the underscore is a reserved character on Windows 2003.

foundFiles = Directory.GetFiles("c:junkwatch_product", "BA*.txt")

IDE :: Setup Project Now Gives Error If The Same File Included Twice Opposed To Warning?

Oct 23, 2009

I include 2 exes in my setup project which share dlls. In 2008 this just resulted in warnings when building but I now get an error instead indicating that the file is already included.I can fix this by excluding them but they will reappear after each build so have to be excluded again which slows the process down - example error message is below:

Error 14 Two or more objects have the same target location ('[targetdir]interop.excel.dll') C:DevelopmentPIMSPIMSSetupPIMSSetup.vdproj PIMSSetup

Hide Member Without Using Underscore?

Aug 8, 2010

I have a class written in VB.Net exposed to COM via the ComClass & ComVisible attributes. The class is then made available to VBA via a TLB. In VB6 you could easily mark a member hidden in the object browser but still available with a check mark. In VB.Net the only way I found to make a member hidden the VBA object browser is to prefixing the name with an underscore.

Is there a way to hide a member without underscoring it?

Program Won't Compile Because Of Underscore

Feb 23, 2011

I've been running the same project on the same computer for months now in VS2010.

There have been no code changes to the class that contains the following [code]...

Recently, when I compile, I get an error that my class must implement event ValueChanged.

When I remove the underscore and bring the Implements piece to the same line, it compiles.

If I then undo checkout and revert it back to what the code was before, it compiles.

Underscore In Label.content In WPF App?

Aug 14, 2010

I have a series of variable values that use an underscore to represent the space between words (e.g., abc_def_hij or klm_nop). When trying to display them as label.content (e.g., MyLabel.Content = DataType) the label always suppresses the first underscore. The examples I gave would display as abcdef_hij or klmnop and I can't seem to find anything that defines this anomaly or how to alter its behavior.

Getting System.Data.DataRowView In Drop Down List As Opposed To Values From Database

Sep 30, 2010

I'm populating a custom dropdown list control on the fly that's tied to data grid using VB .NET 2008. The form will display all the manufactures when the edit button on the data grid is selected.

The dropdown I created works fine. However, when I try to populate the drop down with the respected manufacture values from the database, I only get a value of "System.Data.DataRowView" that being populated in the dropdown list as opposed to my values from the database.

Here's the basic code I use to first create and populate the drop down control:

<asp:DropDownList ID="Manufacturedd" Runat="server" DataSource='<%# m_ItrackerData.Tables("Misc_Manufacture") %>' SelectedIndex='<%# getSelectedManufacture(DataBinder.Eval(Container, "DataItem.Manufacture"))
%>'></asp:DropDownList>

VB 2010 Underscore And Small Rectangles In String Outputs?

Dec 1, 2010

I've made some good progress with my first attempt at a program, but have hit another road block. I'm taking standard output (as a string) froma console CMD window (results of dsquery piped to dsget) and have found small rectangles in the output. I tried using Regex to clean the little bastards but it seems they are related to the _ (underscore), which I need to keep (to return 2000/NT logins). Odd thing is - when I copy the caharcter and paste it into VS2K10 Express it acts like a carrige return?Going to try using /U or /A CMD switch next..

Regex Email Address Validation Fails If Underscore Character Present

Aug 31, 2010

My Regex works, except if the email address entered has an underscore character (_) in it.

Because of my lack of experience with regular expressions, I'm not sure where in my pattern I'm supposed to add the offending character to allow it:

Dim pattern As String = "^[-a-zAZ0-9][-.a-zA-Z0-9]*@[-.a-zA-Z0-0]+(.[-.a-zA-Z0-0+)*." & _
"(com|edu|info|gov|int|mil|net|org|biz|name|museum|coop|aero|pro|tv|[a-zA-Z]{2})$"

He said he fixed it by adding the _ after the numeric check.

I see the A-Z0-9, but I'm not sure which is the numeric check...

.net - Different Increase In Email Size Using SMTP Class To Send An Email As Opposed To Outlook?

Jan 6, 2010

I am sending an email with an attachment using the following Code

Dim msg As New System.Net.Mail.MailMessage(req.EmailFrom, req.EmailTo)
Dim att As New System.Net.Mail.Attachment("C:Documents and SettingsmichaelrDesktop1216259.pdf")
With msg
.Attachments.Add(att)

[code]....

The file size of the attachment is 396KB, upon the recipient receiving the email outlook shows the file size as 543Kb. Strange thing is if I send an email with the same attachment using outlook the file size is 396Kb.I understand that file sizes can increase due to the attachment being base 64 encoded as opposed to just raw binary.What I am failing to see is why outlook send a file which is 396KB in size but in code when sending it, the same file is 543Kb.

DB/Reporting :: Get A Count Of The Physical Pages (as Opposed To Logical Page Count) To Use With A Print Dialog

I have some reports that I use with the MS ReportViewer and I need to get a count of the physical pages (as opposed to logical page count) to use with a print dialog. I've implemented a workaround so the ReportViewer control displays the correct number of physical pages, but is there a way to get that value from the ReportViewer control? The only publicly accessible property gives the logical page count.

Access A "private Virtual" Property Starting With Underscore Through Reflection?

Apr 10, 2011

I was trying to access the following property using Reflection because I don't have the original source code (suppose this was decompiled through Reflector). It seems that something is special about it being "private virtual" or maybe because it has "_" in the beginning of the property. I can access all the other private properties no problem except this one. Just can't figure out what I am doing wrong:

Forms :: Share Data Between Forms (as Opposed To Passing Data)

Nov 26, 2011

Quite a few threads on passing data from one form to another, but I'm struggling to work out how to share data between the two - back and forth.

For example:

Class1 is a class with 10 string properties

Form1 has 10 labels ("Label1", "Label2" etc) and a [Configure] button.
Form2 has 10 textboxes and a [Apply] button.

I want to load with Form1, and create an instance of Class1. Click the Configure button and load Form2, passing Class1. On Form2 I want to manually fill in the 10 textboxes and hit Apply. The Apply should update the Class1 instance and close the form.

Form1's Label controls should then be updated with the data from the Class1 instance.

I'm fine creating the forms and classes, as well as passing the class into Form2 with a custom Sub New(EmptyClass as Class1) constructor. This gets the empty class into Form2, but how can I get the populated class back to Form1?

As Form1 already exists I don't want to create a new instance with another custom Sub New(PopulatedClass as Class1)

It's also key to be able to use the Form2 multiple times, basically ending up with a Data class being displayed as part of Form1 but updated using Form2? (For example if the Class has already been created and populated with data when it's passed back to Form2 for the second time I would pre-load the Textboxes with the values already in the class).
