How To Sort CSV That Imports To Combobox
Apr 21, 2010
I need to have a CSV get sorted alphabetically before/during/after it gets filled to a combo box. What I have is a text file with a list of company codes, and company names in the following format:
companycode,companyname the code below loads the CSV and then fills a combo box with each value. When a user selects the company name from the combo box, the corresponding company code is loaded into a text box and used to upload a file to a sepcific directory based on customer. I've looked at ways of sorting comboboxes, and presorting the CSV before loading, but is there a way to do it during the importing/datafill?

I list folders in my combobox but I'm trying to sort the folders alphabetically and then numerically or vice versa.
My coding to populate my combobox is
With Combobox1.DataSource =
(From folder In New IO.DirectoryInfo("Path").GetDirectories
Select (folder.Name)
).ToArray
End With
Is it possible to sort the combobox?
I have folders that are numbered like 1, 50, 115, 189 etc.
These should display as
1
50
115
189
however they display as
1
115
189
50

I have a ComboBox with several items from C1 --> C999. And I would like to ascend the combobox to be easy to manage, so I set True for Sorted Properties. However, the problem comes after that is for example, it shows C11 --> C110 --> C12, etc. I believe because it counts from left to right. So how can I solve this problem.

Hi,I´m trying to build a form that allows user to choose if he want the combo-boxes sorted or not. The comboboxes are filled when form is loaded, when user clicks on checkbox (chkSortList) then I want the comboboxes to be re-arranged. Can anyone give a hint how to do that ? Tried cmbMerk.Refresh(), cmbMerk.Update() ... but the sort-order do not change. I can re-load the items to the combo-boxes but is there a better way to do it ?

Select Case chkSortList.CheckState

I have a function when fired queries against the database (twice) and returns the results in a dataset. It checks the results (to make sure there are some) then loops through and grabs each row from the returned dataset and imports (copies) it to a different dataset.I also add a primary key into a List so I do not add the same item twice (from the 2nd query) to the dataset.I then return the dataset.The problem? The query works and there is a returned value.. however the dataset in which I aim to import the row(s) to does not keep the imported row.
Public Function GetClientsWithMonitors(ByVal argHost As FOO.Interfaces.BAR) As DataSet
Try
Dim localDataSet As New DataSet()
Dim clientsWithMonitors As New DataSet()

how do you know what imports to add to the top of the page? The only way I have figured it out was to look up other people's code with the methods I am using to see what is used.

I have created some code that pulls certain data from sql and saves it as a txt file (columns seperated by commas). I can't seem to find a way to import these newly created txt files into excel. I create 2 txt files, and would like to import the 1st one to sheet and the 2nd one to sheet 2. Then add a row to each sheet and fill in headers.I have the code down, and create the workbook and sheets and adding the rows and headers, but I can't seem to find a way to do an import into excel through the vb.net code.

I knew from here that we have to do the explicit imports for child namespace because imports will not include the child namespace.But my question is that if I do "imports System" whether it will include all the classes/methods inside that namespace in the IL/native code or only referred ( used inside the application) will be included in the IL/native code.

I have never used LINQ before, and I am getting an error in an application that does use it. This is a VB.NET (.NET 2.0) project in Visual Studio 2008.
Here is the offending code:
Dim orderedRows = From r In resultRows Order By r.FIELDNAME Select r
And here is the error (names changed to something generic, but otherwise accurate):
Expression of type '1-dimensional array of
Company.OurLibrary.FunctionalArea.Library.StoredProcStuff.USP_MYPROC.ResultRow'
is not queryable. Make sure you are not missing an assembly
reference and/or namespace import for the LINQ provider.
C:projectfilename.vb
So I recognize that I need to import LINQ libraries. This link led me to add "Imports System.Linq" to the file, but that is an unresolved reference. Based on the same link, I figured I needed to add a reference to "System.Core" to my project, but it is not listed as an available option when I try to add a reference (nor is it already checked).

a common VB.NET class should look like the following:
Public Class MyClassName
End Class
Besides, I have already seen, if I remember correctly, all of the import statements visible just like in C#:
Imports System
Imports System.Data
Imports System.Linq
Public Class MyClassName
End Class
How to make these default imports visible by default in VB.NET using Visual Studio 2008?Is there some setting or the like in the options I shall set?
