Select A Non-contiguous Group Of Cells From Multiple Columns Within A Row That Is Defined By A Variable?

Nov 10, 2010

I am trying to write a module that will select cells from multiple, non-contiguous columns within a row that is defined by a variable. The column numbers are known and are unchanging. For example, my worksheet might look like this:

A B C D
Row 1 X X X X

I want to select cells A1, B1, and D1; however, I don't want to use the row number (1 in this case) in my code. Rather, I want the row number to be specified as a variable. The code I am writing is inside a For/Next loop, so I would like to use the iterative variable (i in this case) to define the row number. That way, every iteration of the For loop will select cells from a different row.

Select A Range Of Non-Contiguous Cells In A Column, Then Return The Address Of The Last Active Cell

Jan 4, 2011

With an excel file opened, i'm trying to:

Select a Range of Non-Contiguous Cells within a Column, then return the address of the last active cell.

Below, is what I have so far: Note the section maked:

' I can't get the next bit to work: '

To make it work, so far :(

1. Create a new Project using VS-2010.

2. By default, the form should be displayed as "Form1.vb".

3. Add a Label (No need to name or set anything).

4. Add two buttons (Again, No need to name or set anything).

5. Double click on the Form...

6. With the form code displayed, Select all, then paste the following.

'Option Strict Off
'Option Explicit On
Imports System.IO

Linq To Datarow, Select Multiple Columns As Distinct?

Apr 16, 2010

basically i'm trying to reproduce the following mssql query as LINQ

SELECT DISTINCT [TABLENAME], [COLUMNNAME] FROM [DATATABLE]

the closest i've got is

Dim query = (From row As DataRow In ds.Tables("DATATABLE").Rows _
Select row("COLUMNNAME") ,row("TABLENAME").Distinct

when i do the above i get the error

Range variable name can be inferred only from a simple or qualified name with no arguments.

i was sort of expecting it to return a collection that i could then iterate through and perform actions for each entry. maybe a datarow collection?

As a complete LINQ newb, i'm not sure what i'm missing.
i've tried variations on

Select new with { row("COLUMNNAME") ,row("TABLENAME")}

and get:

Anonymous type member name can be inferred only from a simple or qualified name with no arguments.

to get around this i've tried

Dim query = From r In ds.Tables("DATATABLE").AsEnumerable _
Select New String(1) {r("TABLENAME"), r("COLUMNNAME")} Distinct

however it doesn't seem to be doing the distinct thing properly.

Select Multiple Lines Then Push That Out To A Single Variable

Nov 20, 2011

I have a listview box. I load the listview up from a text file and everything is divided into three groups. I need to be able to select multiple lines then push that out to a single variable, separated by commas. Two things are happening that are problematic:

1) If I just have it set to smallicons and no checkboxes, anything I select is highlighted right up until the control loses focus at which point everything un-selects.

2) If I turn on checkboxes, I can click boxes and they stay selected when I lose focus BUT the checkboxes are cut off on the left side of the control. (The checkbox appears to go off the edge of the control.) There's plenty of space in the control for the checkbox and the listed items.

How To Group Distinct Columns In A Linq Query

Nov 4, 2010

The following data is created by joining two sql tables together:I would like to group together distinct rows of DateStamp/UserName/ StudentName/ InstructorName/TableName/PrimaryKey (I'll call this 'group records') and then group under these ColumnName/PreviousValue/NewValue (I'll call this 'subgroup records')The end result would be that I could iterate through the 'group records' - there would be 5. In each 'group record', I could then iterate through the 'subgroup records'. The 5 groups would contain 3, 2, 5, 2 and 1 subgroup records respectively.What would be the syntax to create a query to do this? Ideally this would be in a vb.net linq syntax.

Linq To Sql, Aggregate Columns ,group By Date Into Listview?

Aug 3, 2011

also i have a table called Orders with several columns, they contain information about the order and store the ID of the Customer they belong to.Question is: how can i query that table with (preferably) linq (the datacontext is from LinqToSql) to return the following dataI want to search for any entry with the matching CustomerID which took place, group them by Year, Sum the Totals respectively and add them to the listview?I now i could use lamda expressions and aggregate, its just not clear how (option infer on,db is a datacontext object,CustomerID is an int32 variable):

Dim Orders = (From order In db.Orders Where order.CustomerID = CustomerID).GroupBy(Function(p) p.Date.Year).GetEnumerator
I reckon i'd have to create an anonymous type like the following:

Section And Title Are Columns In A Dataset Defined By DtName That Exists

Aug 13, 2009

I am having very odd behaviour from my compiler when i run my program, i have two practically identical snippets of code that are doing pretty much the same thing: both are populating nodes on a treeview using information from the treenode above but when the program runs one of the snippets tells me at runtime that something i have defined is nothing. [code] section and title are columns in a dataset defined by dtName that exists, and the where bit is refering to a column where the entries match the value assigned to volume. which is 1 in the first iteration.

Original DataTable Object Has Columns Added When Variable Has Columns Added?

Oct 6, 2011

I have a datatable property called prpParametersTable in a class called clsBatch. I have a procedure that sets a datatable variable called dtP equal to prpParametersTable at the beginning of the procedure. I then add three new columns to dtP.Here is my problem. When I add the three new columns to dtP my original table prpParametersTable also gets those columns added to it, why? I only want to add the three columns to dtP and not prpParametersTable. How can I do that?

Private Function prvfnc_InsertBatchParameters(ByRef cnn As SqlConnection, ByRef trans As SqlTransaction) As String
' set new columns that have BatchID, Insert DateTime, and UserID for the SQLBulkCopy method below
Dim clm As DataColumn
Dim dtP As DataTable = clsBatch.prpParametersTable

Select All Cells In A DataGridView Column / Row On Header Click?

Apr 2, 2012

I have a DataGridView with SelectionMode = "CellSelect". I do this because I want the user to be able to click the Column Header and drag the column to a different DisplayIndex. They move the column by clicking and holding down the left mouse button, then moving the column. I also want the user to be able to click the column header and all the cells in the column would be selected. But if I change the SelectionMode property to "FullColumnSelect" or "ColumnHeaderSelect" the user can no longer move the column.In the code below, I can select all the cells in the DataGridView just fine, but I can't select all cells in a particular Column or Row.

Multiple Datagridviews Cells Being Selected?

Feb 16, 2012

VB 2010 form has 1 panel, 1 DGV in the panel, 1 TabControl with 3 tabs in the panel each tab has a DGV all 4 bound to the same DataSet through code.

I have a form that has multiple Datagridviews on it, 1 in the main portion of a panel and the other 3 in a tabcontrol. If I click on cell 0,4 of DGV1 cell 0,4 of DGV2 is also "hilighted" and the same goes in the reverse order. If I click on cell 1,4 in DGV 1, cell 0,1 is hilighted in DGV2 (basically it stays with the last selected col and what ever row for that DGV).

This isn't the functionality I'm really looking for here, when I single click or change cells on any of the DGV's I don't want any of the others doing anything.

As you can see there are 2 cells selected this was created by a single click in the 4th cell of Param0
