Fill Fields In A Structure In A Single Line Of Code?
Sep 21, 2009
Just suppose that I define a structure, and an array such as
Structure Person
Dim First_Name as String
Dim Last_Name as String
[code]....
Can I fill in my list of people using a single line of code for each record? Something like this, it doesn't work, but this shows the sort of thing I mean.
My_List(0) = {'John', 'Smith', 24, '555-1234'}
My_List(1) = {'George', 'Jones', 31, '555-8123'}
My_List(2) = {'Tom', 'Green', 40, '555-3434'}
It's easy enough to fill it in line by line. I could do that without problem. But I want to be able to look at the code and see the contents of each line. Doing it as above would make it easier to read.I could make it a multidimensional array of strings, rather than a structure.If it makes any difference I'm using Visual Basic 2005 Express Edition.

I am converting a VB 6 app to VB.Net. In the vb 6 version I have a table that contains roughly 80 fields. Over that table the users currently have a single form which gives 12 diferent views. Each view is placed on a different tab, which, although giving a distinct set of fields per tab, also leads to a ton of duplicated code. Changing the underlying table is not an option.
What I would like to do is to use a single datasource (containing all 80 fields), a single datagridview on the form, and have a combobox act as the filter choice for the differing views. Does my solution seem like the right way to handle this? If so, I'm not sure I know which controls would best be used.

I have a class (using a class rather than a structure only because I can set a default field value for the fields I declare in the class) and I'm using a web service that returns information (demographic information) in JSON. I am using LINQ to get the values of each "entry" from the returned list and in that, I have to parse through and pull out the actual data that I want.Here's how I have it doing right now (just a start, there are 44 of them total, thus my question which will follow the code):
Dim returnedStats = From ljo As Linq.JObject In returnedObject.SelectToken("results")
'
'
For Each stat As Linq.JObject In returnedStats

a user copies multiple lines of text (say, from an email) into the clipboard. Based on my observations, when one tries to paste the text into a single-line textbox, only the first line is actually pasted in. (I am aware that the "obvious" solution would be to set the Multiline property to True, but there are reasons I am looking to avoid this and to put multi-line data into a single line.)
In the TextChanged event handler, I wrote code that parses the clipboard data to successfully convert it to a single-line, comma-delimited format.
Private Sub txtMassTrackingNo_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) _
Handles txtMassTrackingNo.TextChanged

I have a simple app where I am trying to fill in a bunch of fields (Client Info). The controls are bound to a DataSet (ClientDS and the table I need is Clients). I have a data navigator which should allow me to scroll through the selected info for each client. I have the following code

The problem is ... it won't accept the Clients in (ClientDS.Clients). ClientsDS is the existing dataset I've created and to which the controls are bound..

Basic scenario is that I need to programatically fill out a PDFs text fields that resides on a webserver. The fields will be mapped and filled out with data contained in a CSV. The PDF must be opened in the browser (browser control or ie/ff/chrome/etc) and edited in place. Cannot be downloaded, filled out, and uploaded (it must be filled out and submitted using the submit button in it; I've tried editing the buttons submission path to no avail).Thus far I've put a web browser control on a form and made it navigate to the website, login, and load the PDF file. How do I interact with the PDF file thats open in the web browser control? Looking through various PDF libraries, they seem to mainly interact with a closed pdf located on the harddrive, make the modificatio

I have tested my code in order to pass single value to single parameter field in crystal report from VB.NET Form, it is ok but the problem is that I want to pass multiple values to only one parameter field called "Product Name" and it displays only one last record.
I want to display like this
Receipt : 0001 Product Name
pencil

I already set parameter field "productname" for allowing to multiple values, but it is still the same.

I'm not getting this at all I suppose. I've tried so many variations to split the lines into individual fields and I still cannot get it to do what I want.
I have to get lines from a sequential file which read like:
CODE:
And load them to a listbox like this:
CODE:
With the ID # padleft(10, "0") and the commas eliminated, and only the Last Name, First Name and Middle Initial showing.
This is my mess of a code (it is just one of many variations)
CODE:
I've got the ID field right but the rest just shows up as it is in the file commas and all.

I need to put 2 different fields on the same line/row/subscript, into a one-dimensional array or list. I've done this before with a delimiter and then parsed it out later, but I wonder if there is a nicer way to do this?

"John,Address1" PERSON_ARRAY(0)
"Greg,Address2" PERSON_ARRAY(1)

I am trying to create a data structure that would look something like this: [Name; xLoc; yLoc; zLoc; [Jagged Array]] Note: Name needs to be dimensioned as a string, xLoc and so forth as integers.

How can I structure my classes so that the user interfaces though a single class while the supporting classes are hidden from their view? I think its best understood in an example:
Public Class MyInterface
Public Economic as EconomicClass
Public Sub New()
MyBase.New()
[code].....
So you might ask why am I even separating them? It's strictly for others who will be working with this interface. I need to funnel them though a logical structure:
interface.Economic.MyMethod
interface.Currency.MyMethod
etc
This way everything is already handled for them in the background and they only need to run the method they need. I don't know if I can have it both ways in VB.NET.

How do I read a line from a database using WHERE? I've read this post but it doesn't really cover it and the forum search throws out the words, 'From' and 'Where' as being common. This is my bit of code but it just skips over it as if it doesn't exist so presumably there's an error, I dunno. I'm trying to read an entire line from the database where it equals the value of 'getweek' where 'getweek' is a variable.

I'm using Visual Basic 2008I've been trying to create a auto typer where I can put a whole page of words into a rich text box and the auto typer then pumps the words out one at a time.The code that I use is:
Timer1.Interval = TextBox1.Text
SendKeys.Send(RichTextBox1.Text)
SendKeys.Send("{Enter}")
That code would just type all of the words at once. Also, I'm putting the words in a rich text box. How could I save the rich text box so that each time I load up the application it still has all of the words in it?

Is there any box type in vb.net that is multi lined, however stays as a single line and when you click on it , it will open up into a multi lined box (because I want 10 of them in a small area , in single lines will be perfect but needs to have lots of information stored in each one) and then when the user clicks out of the box / into the next one, it returns to its single lined state?

give me a working regex expression (C#/VB.NET) that can remove single line comments from a SQL statement ?I mean these comments:
-- This is a comment
not those
/* this is a comment */
because I already can handle the star comments.I have a made a little parser that removes those comments when they are at the start of the line, but they can also be somewhere after code or worse, in a SQL-string 'hello --Test -- World' Those comments should also be removed (except those in a SQL string of course - if possible).Surprisingly I didn't got the regex working. I would have assumed the star comments to be more difficult, but actually, they aren't.
As per request, here my code to remove /**/-style comments (In order to have it ignore SQL-Style strings, you have to subsitute strings with a uniqueidentifier (i used 4 concated), then apply the comment-removal, then apply string-backsubstitution.
static string RemoveCstyleComments(string strInput)

string strPattern = @"/[*][wds]+[*]/";

For example the user has typed a list of names in a text field (1 on each line)
jerry
mark
mark93
ewji84
fjkewo93
the program will auto fill this in the submission form jerry
when it finished the first registration now moves on to the second string:
mark
and so on....
I already made the multiline text boxes and the main functionality of my bot,
all I need now is the program to submit multiple keywords from user input and it should be 1 keyword in the field per submission.
