View 7 RepliesI have a situation where a class's properties are being exported/imported from an Excel sheet. Each property is in a specific column, so I want to make a mapping between each property and column # (a Dictionary collection would be sufficient). That way I can just loop through each property and/or column in the dictionary when read/writing data (maybe something like Class1.PropertyA = ws.Cells(curRow, Propto ColDictionary(PropertyA???).value). But, you obviously can't treat properties like other value types, so I don't know how I would store a property in a dictionary for this purpose. So could this sort of thing be achieved via reflection, or am I off-track?
View 8 RepliesThis is my programs complete code, the only problem is i want to fix the amount of decimal places that show up in my gridview. The problem is if i do this on the asp side the location of the column gets thrown off and the column is duplicated. I figured if i just remade the table on the asp side it would work only problem is if i remove the sql for that particular column the asp side column cannot get data.

i am checking for if the column code is Null or not in that same i wnat to check whether the column has any of the duplicate values then i should mark as isGoodRecord = 2,
If (IsDBNull(Row.Code) Or Row.Code = String.Empty) Then
Row.IsGoodRecord = 2
ErrorDesc += "Code is blank;"

I have a program that reads a 3rd party .txt file using OleDB into a DataTable When it reads it, its creating a column alias name, and works fine.
gives the user the ability to save a record to the .txt file by using an OleDb command statement and inserting a record into the DataTable then I re-write the file using stream writer because my understanding is you can NOT write directly into the .txt file.
I have created the program to read column postion rather then name since some data providers call columns different names, but I havent encountered a provider using the same name for 2 different columns.
I am using the TextFieldParser to read a 3rd party .txt Tab Delimited File Sometimes the file contains duplicate column names and subsequently I cant create my DataTable.
How can I check for duplicates first and change the name of the duplicate fields so I can populate my Table?
Example:
I have two columns called ST and would like to Change of of them to ST1 or something similiar to populate my table
Dim safeFileName As String = IO.Path.GetFileName(Me.OpenFileDialog1.FileName)
Using myReader As New Microsoft.VisualBasic.FileIO.TextFieldParser(safeFileName)

I have a gridview where I need to have column names within 1 sortable pageable gridview as the same name, but when I set up the sql query as
select x as 'col', y as 'col', z as 'col'
it shows up in the gridview with autogeneratecolumns on (theres a lot of columns in the page I don't feel like not autogenning it)
and it shows up as
col
col1
col2
in the gridview but I want it to just be col, col, and col. I understand that this could cause a sorting problem without turning autogenerate columns off, but I was hoping there was some type of work around.
I am trying to create the code which will stop duplicate entry of an Account Number being entered in the column 'Account Number'.

I am sending values from Combobox and Textbox to Access Database in VB.NET.I am phasing the problem when i enter the Duplicate values.In the database one of the column is Indexed.(Yes Duplicates not allow)That column i bind to Textbox("txtperson1").I used the TRY and Catche method to solve the Indexed Problem.when i run the application the value which i enter is not a duplicate that value save on the db.

I have tried to do this buy use something i saw on msnd's website:
Dim foundRow() As Data.DataRow = customerDS.Tables("Details").Select("HNCNO Like '33%'")
However if i change the line to notice the i beside the like
Dim foundRow() As Data.DataRow = customerDS.Tables("Details").Select("HNCNO Like 'i%'")
but i get Index was outside the bounds of the array. Ok i know that means that there is nothing in my array. What i would like is to find the duplicate row associated i. you will probably understand me better when you see the code.

I am working on DataEntry Forms in VB.NET There are two controls are having in a present window. One is Combobox and one is Textbox. Combobox values are Mobile, FAX, E-mail. By the mistake some one enter the values like , In the combobox-E-mail and in the Textbox-9987453434. Finally these are saved on the Database. But i want to Re Enter the values.
For this i was selected in the Combobox-Mobile and in the Textbox-9987453434. These are the right values i want to save on the database.
But here the problem is that Phone number column(Textbox) is Indexed. (Unique) or No Duplicates in the database. Now i want to update only one column which is coming from Combobox in the database.

View 3 RepliesThe issue I'm currently having is mapping multiple GUI fields to object properties (i.e. Presentation layer to Business Logic Layer mapping). To be more specific, this is in VB.Net 2.0 WinForms. The nature of the solution requires us to have 4 columns which exhibit the same type of behavior on our GUI - each column consisting of 11 textboxes (we'll just use this small sample size, as the problem extends beyond 11 textboxes).
What I am currently doing is setting the tag of each textbox in all four columns to a value like so:
Textbox1.tag = "name"
Textbox2.tag = "type"
Textbox3.tag = "speed"
[Code]...
As you can see this can get very bad, rather quickly. Currently we're setting 43 some odd properties that can be mapped to -- thus that select statement is extremely long -- many of which are embedded in multiple methods to try and attempt DRY (I've watered down the code to essentially a conceptual implementation).
Question is: how can I refactor this? I've attempted using a dictionaries/hashes to a certain extent, but it either became overly complex, or just plain didn't make an implementation sense as it convoluted the problem even more.
I've followed the instructions found at the letter (albeit also adding the parameters to pass a username and password), but have had no success connecting to a network drive that requires authentication to access.

what options do I have for creating a VB.Net application with a mapping framework; obviously I am not going to write my own. So is there any OFFLINE components free or otherwise that I can use?
Application Background : Basically I have a mobile device that sends its location back to a socket server (I am writing using .Net sockets) every 10 Seconds (possibly longer 10min, not decided). The client (which I will also write and need the map component for) will login to the server and download the latest number of GPS points and simply plot them onto a map surface (thus the maps need to be of street level quality). Although the map database can be updated over the internet, I have to assume the user does not have an internet connection. So using something like Google earth is no good. Initially I need the UK only, but will need the option for Europe and possible the USA later on.
