VS 2005 Reading CSV File?
Jun 13, 2010Normally CSV files I work with lookes like this : d,e,f,g,1,2,3,4,5 What I am trying to do now is importing a CSV file that contains a title field, HTML description field ect. so at the end the CSV file format looks like this:"Record Title",1,2,3,"HTML description, which contains "",, ect",1,2,3,4,5, I need to know how to work with the above CSV format, where all the strings are inclosed with "" and may contain commas, so I can't use the split function as is to split where it incounters a comma as it may be part of the HTML description or Title field.

View 2 RepliesVS 2005 Reading An XML-Type File?
Jun 22, 2010I am trying to read in and eventually manipulate an 'XML-type' file. I have picked up a hobby called 'Geocaching', some people probably have heard of it, where you use gps coords to locate items placed by other people. Well, you can download the gps coors within data files from the website,'Geocaching.com' and these files are in a XML format.
There are a lot of programs out there that people offer, some are better than others, but I am not happy with the results. So, I am trying to see how I can use these files myself and create my own program to use the data in a way that I want to use it.
I have tried to use Linq, XMLdocument, XMLreader and probably a couple of others over the past week. I have had marginal sucess with each of these methods, but nothing great and I owe that to my lack of knowledge.
I eventually hope to add the data to a Access db that I am using and manipulate the info from the db.
I am attaching a sample of one of the downloaded files and if someone would have the patience to help me work my way through it, p.s. The file typically ends with '.gpx', but since its an xml and thats what the system recognizes, I added the extension in order to upload the sample file.
VS 2005 OleDb - Reading TXT File Into DataTable
Aug 15, 2011My program reads a 3rd party .txt file using OleDb and reads the file into a datatable. It's overall working fine except a user will occasionally have a problem reading a file. At this point.
Line that gets hung up
Try
Dim comm1 As New OleDbCommand("SELECT * FROM " & safeFileName & " Where " & Status & " = '" & StatusClosed & "'", con)
Dim dasold As New OleDbDataAdapter(comm1)
dasold.Fill(dtsold)
AddColsold()
[Code] .....
It can not retrieve a date for one of the fields, then gives error and does not get dates for each records after the one it gets hung up on but the date is in the file. If I open the file in excel and play with the column sizing, for instance just autoformat column width then it read the date and will work fine. I have looked at the file in notepad and cant see anything wrong in particular on the record it gets hung up on. I have no control over the .txt file since it comes form a 3rd party.

VS 2005 - Reading File Into Buffer / Encrypting And Writing Data
Sep 29, 2009I'm reading a file into a buffer using the Space function. Then I'm using blowfish dll's to encrypt it, and want to write the encrypted data to a txt file. (I realize you can use .NET cryptography classes, but I need to use these old blowfish dll's for this project.) Anyway, when when I encrypt the data in the buffer, I can see all encrypted data, but when I write it out to a file, I get a few lines of encrypted data and the rest of plain text.

Interaction With Database (Reading / Writing Tables And Fields)
May 2, 2012Using Visual Basic 2008 express, I would like to access a database with 2 tables, one table (useraccounts) which has Users and Password and ID, and the other table which has information (linktable). Basically I would like to do a login form which reads from the table useraccounts and be able to create new users which will write into the database.
Another is that I have a form with a number of links which I would like to store in the table 'linktable' and it basically just gets the links from the table and straight to the form where it is used. I have tried using access or the .mdf files that visual basic has but I have been unable to find an answer for either.
I wouldn't mind using either access or the .mdf file for the database, I would just like it to work. Overall I am trying to get:
Login form which reads from database table 'useraccounts' and has a new user feature
Just a form that can read / write to the database once the save button is clicked.

VS 2005 Select All Fields And Cdbl For One?

Refactoring A Module Into A Class: Changing Shared Fields To Instance Fields
Nov 14, 2011I'm currently refactoring an old Visual Basic DLL (VB.Net), which stores all of its data in one module called Globaldefinitions as public fields. There are about 200 fields, referenced thousands of times all around the code:
Public Module Globaldefinitons
Public a As Short
...
Public zz10 As Double
[Code]...
I need to change the module into a class with non-shared fields. This means, each and every of these thousands of references needs to reference the instance of that class:
globalDefinitionsInstance.a = 5
How do I go about this efficiently?
Regular expressions operating on the source fall flat. Refactoring tools like Re-Sharper or CodeRush don't seem to offer this functionality. Visual Studio 2010 cannot do it automatically either.
Can The Initialization Order Of Class Fields In .NET Be Influenced By References To Other Fields
Jun 19, 2011Class Foo
ReadOnly name As String
Public Sub New(name As String, dependentUpon As Foo)
Me.name = name
[code]....
The output of New Bar() is:
Dependent created. Dependent upon nothing.
Independent created. Dependent upon nothing.
It seems fields are initialized in the same order as they appear in the source code, which (a) leads to an unexpected result, and (b) seems a little puzzling, given that one is normally not permitted to read from uninitialized variables in .NET, yet that seems to be working fine above.I would've expected VB.NET to be smart enough to initialize referenced fields first, and only then those that reference it; i.e. I'd have liked to see this output instead:
Independent created. Dependent upon nothing.
Dependent created. Dependent upon Independent.
how to get VB.NET to behave like that instead, without simply having to swap the declaration order of dependent and independent inside class Bar?
Create Word Form Fields With Memo Fields From Access?
May 27, 2012I'm trying to create a table in Word using data from a table in Access. There are four fields in the access table that I need. 3 fields are text which I can populate the Word without any issues. However the fourth field is a memo with >255 characters.I'm struggling to come up with the proper code to allow me to populate the Word field with the memo data that has more than 255 characters. The code I have so far is listed below. But when it hits the memo field, it crashes on the line I marked with **. I know it's not text, but I've tried many different field types, but nothing has worked so far.[code]...

VS 2005 'Global' Key Reading
May 20, 2009I'm in high doubt of this actually exsisting but still want to check, is there a way so that whether the VB form has focus or not it can still read the keys being typed? I am using winamp and i type something and the form picks it up, so when i type something like ctrl+"exit" the application closes. the thread should be running as the form is Always on top, however for obvious reasons the form does not have focus, so something like keyPressEventArgs won't have an effect, is there any way that you can catch the keys in a global perspective.
