Avoiding Namespace Declaration In Each File?

Sep 25, 2009

One feature of C# compiler is that namespace declaration by default follows the folder name structure in the project. By e.g. you have MyProject1MyDrawing and inside you create a class MyPoint the namespace for MyPoint will be MyProject1.MyDrawing

In VB I cant see any namespace declaration(apparently it implicitly 'inherits' the project(MyProject1) namespace). If I create a MyPoint and MyLine clases in the MyDrawing folder I need to surround each of created classes with "Namespace MyProject1.MyDrawing"..."End Namespace".

Is it possible to automatically name the namespaces like in C# by the folder name?

.net - Import A Tab Delimited File Into A Table : Avoiding 'End Of File' Errors?

Nov 4, 2009

I'm trying to import a tab delimited file into a table.The issue is, SOMETIMES, the file will include an awkward record that has two "null values" and causes my program to throw a "unexpected end of file".For example, each record will have 20 fields. But the last record will have only two fields (two null values), and hence, unexpected EOF.

Currently I'm using a StreamReader. I've tried counting the lines and telling bcp to stop reading before the "phantom nulls", but StreamReader gets an incorrect count of lines due to the "phantom nulls".I've tried the following code to get rid of all bogus code (code borrowed off the net). But it just replaces the fields with empty spaces (I'd like the result of no line left behind).

Public Sub RemoveBlankRowsFromCVSFile2(ByVal filepath As String)
If filepath = DBNull.Value.ToString() Or filepath.Length = 0 Then Throw New ArgumentNullException("filepath")
If (File.Exists(filepath) = False) Then Throw New FileNotFoundException("Could not find CSV file.", filepath)

[code]....

I've tried using SSIS, but it encounters the EOF unexpected error.

Adding Namespace Attribute To XElement - Prevent Blank/empty Namespace On Child Elements?

Mar 17, 2011

I need to read an xml document from a database record into an XDocument object in order for it to be deserialized. So that the deserialization will work, I need to apply a specific namespace to each of the level 1 elements. So XML looks a bit like this:

System Namespace Conflict With Sibling Namespace

Nov 16, 2011

This class is located in the namespace Acme.Infrastructure.Interface.A class with the same name EventArgs exists in the System namespace.In another project in my solution I have a class Acme.BusinessModules.MyModule.MyClass.When attempting to use the EventArgs class I have to fully qualify the class name or the compiler thinks I am using the System.EventArgs class.My understanding of namespace resolution was that the compiler would first look for the class in the current namespace, and then its parents. It seems that the compiler checks in System before it checks in sibling namespaces. Is it correct that System is checked before the sibling? Or is this behaviour caused by other issues (Imports order?)?

I have downloaded and installed Visual Basic 2008 Express Edition today, as my hard drive that had Visual Basic 6.0 is getting old and was nearing the end of its life cycle.

Private Sub GetNames()

Select File/folder In Namespace Extension In Windows Explorer?

Jun 9, 2012

I am having a namespace extension implemented, which is visible in "MY Computer". I want to write automated test cases to browse through the same. I am able to open the explorer window till the namespace extension. as -
Process.Start("explorer.exe", "shell:::{CLSID of my namespace }")

next I want to search for a particular folder name inside the window opened. For example if i give input as "temp", then my mouse should move to "temp" folder in the namespace explorer window. then I double click on the mouse's current position and enter that folder. next i give input as "doc1.doc", then my mouse should be able to locate & move to "doc1.doc" file. Also getDirectory or GetFile etc APIs won't work because I don't have a standard drive associated with my namespace & don't have a relative path either.

Generic DAL Avoiding Reflection?

Oct 13, 2010

I'm working on a new DAL for my latest project. As the performance is essential I'm avoiding late binding/reflection as much as possible. One central part is the DAL function for populating Business Objects.One class is called in order to connect to the database with the given SQL (stored procedures can't be used in this environment) and the given Business Object or List is populated. As different Business Object types will be populated by the same function I made an Interface that all of the Business Objects implements with the Sub called "Fill". The question is - will reflection be used in this scenario? My thought was as I'm "describing" the objects trought the interface the compiler doesn't need to use Reflection.

Avoiding 'Microsoft Excel' Prompt

I'm writing the following bits of code for a SaveFile Dialog box in Visual Basic 2010.NET. The code works well as the XLSX file is created and opens in Microsoft Excel. However, the problem that I am having is that if the program overwrites a file, the user is getting two prompts. One prompt is from the program's own SaveFile dialog confirming the choice. The other is from Microsoft Excel asking you the same. It's as if the program is running in the background.[code]

Avoiding Referential Integrity While Updating

Jul 4, 2009

I have an MS Access database and an MS Visual Basic 2008 front end.I get this error when trying to update a record that has related records:The record cannot be deleted or changed because table 'X' includes related records.I only want to update one field in the row in the 'parent' table which is not the primary key field of either record but the 'Update' command seems to want to rewrite the whole datarow. Rewriting the whole row causes the error (as this updates the primary key). If I switch off refrential integrity checking in the underlying database this solves the problem except that I want to maintain referential integrity so its not really a solution. I have tried beginEdit and EndEdit with no success - same error.Is there a way to update just one field in a row and write that back to the database?

Avoiding Updating A Form From A Thread?

I've seen a good bit written on avoiding updating a form from a thread.However,I was wondering if that was a problem if the thread exists in an object that programatically builds the form?Thus the form and associated logic exist within the same "thread space." Seems on the face of it like it would work since everything in the form should be in a single dispatch queue.

Avoiding Boxing / Unboxing On Unknown Input

Feb 25, 2011

I am creating an application that parses an XML and retrieves some data. Each xml node specifies the data (const), a recordset's column-name to get the data from (var), a subset of possible data values depending on some condition (enum) and others. It may also specify, alongside the data, the format in which the data must be shown to the user.

The thing is that for each node type I need to process the values differently and perform some actinons so, for each node, I need to store the return value in a temp variable in order to later format it... I know I could format it right there and return it but that would mean to repeat myself and I hate doing so. So, the question: How can I store the value to return, in a temp variable, while avoiding boxing/unboxing when the type is unknown and I can't use generics? P.S.: I'm designing the parser, the XML Schema and the view that will fill the recordset so changes to all are plausible.

.net - Avoiding Overlapped Bookings In Booking System Application?

Aug 22, 2011

If a booking is present in database on 12/27/2011 at 5:00 pm for 2 hours and i try to make a new booking on 12/27/2011 between 5 to 7 pm then my code generates an error message. Even if i try to book at 4:00 pm for 2 hours it generates an error message as the 2nd hour will be overlapped here with already made booking from 5:00 to 7:00.

Now here comes the problem part. When day changes it doesn't generate error message i.e. IF a booking is there on 12/27/2011 at 11:00 pm for 3 hours then it should not allow new booking till 12/28/2011 2:00 am but when i try to book 12/28/2011 at 1:00 am it saves it in the database and doesn't generate an error message. I want an error message generated in such a case.

I am using two separate fields in database one for time and one for date. Both of them have DateTime datatype.

newtime refers to time on which i'm trying to make new booking addednewtime refers to time after adding the duration to time on which i'm trying to make new booking
