Access Value In Named Range In A Worksheet?
Sep 1, 2011I'm working on converting an Excel VBA project to a VB.net Office Solution. In VBA accessing a named range within a sheet was pretty easy.Sheet1.Range("NamedRange")would give you the value in that cell.
In VB.net I've tried several different things, all ending in failure. [url]...
I'm using one of the Visual Studio Excel 2010 Document template, and I managed to set a value in a named range on a sheet. The template creates a class for each tab on the worksheet, so I was able to do this.[code]...
Excel Automation In VB2008 And Dynamic Named Range?
Nov 7, 2009Having created a small (Excel Automation) VB Appl. to manipulate and present data from Excel sheets in an organised form, I ran across a problem resulting from creating a named range on a sheet, the code line:
oWB.Names.Add("DR_AppData2", RefersToR1C1:="=OFFSET(AppData!R3C1,0,0,(COUNTA(AppData!C1)-2),1)")
seems to work as expected, my only issue here is that this was written on a System that is US-en, and when trying this on a PC DE-de - we have users with varoius language sets - the code fails with a COMException. The only cure I have found to date, is to write the German language version of this:
oWB.Names.Add("DR_AppData2", RefersToR1C1:=BEREICH.VERSCHIEBEN(AppData!R3C1;0;0;(ANZAHL2(AppData!C1-2);1)
How can I write my code / what tools do I need to use, in order that my application will work with any Excel language - and me not having to know all possible equivalents for a particular command or function?
Reading Named Range Into Array - Constant Expression Required
Mar 11, 2011I need to read a named range into an array. Then if the value in the 1st position matches a static value, read the value in the second position. I've been looking into array's and this is what I think will work, however I get a compile error on the columns.count "constant expression required". Is it because in the DIM statement I'm attempting 2 things? This is a macro in Excel. The range name is Data1 and the string comparison is "AnyString". The second value will be an integer.
Sub macro1()
Dim rng As Range
Dim x As Integer
Dim y As Integer
rng = Range(Data1)

Clearing A Range Of Cells In A Row?
Apr 28, 2012is there a way to select a range of cells in a worksheet and clear the data in them?i DO NOT want the WHOLE ROW to be deleted, only a few selected cells (they are all adjacent to each other)and i don't think the ActiveSheet.ranges method works as:
1) the coordinates of the cells in the row to be cleared are determined logically by a VBA sub, i know how to get the coordinates, just dunno how to delete the row
2) this needs to be applied in different areas of the worksheet AND across OTHER worksheets as well.
I'm quite sure I have the logic needed to find the coordinates just need to know how to clear the cells if there is a way to do it that is similar to ActiveSheet.cells ( row, column ) then it would be best from my understanding the ranges method only takes in letter and number formats in strings... i need something that takes in number and number?

View 3 RepliesSelect A Range Of Non-Contiguous Cells In A Column, Then Return The Address Of The Last Active Cell
Jan 4, 2011With 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.

.net - Remove Single Quotes From All Cells In A DataTable?
Apr 2, 2009I have a table with many values inside of it that might have single quotes around them. I need to create a duplicate table without those single quotes. I can't modify the original table as I need to use it, 'as-is' later.
I've done this with a table.Clone and using a foreach to loop through the rows and columns removing single quotes as I need and then putting that new row into the new table. It works and it's straight forward.....but
I'd like to do the same thing using LINQ. This was my attempt....
Dim myResults = From myRow In dtTable _
From myItem In myRow.ItemArray _
Where TypeOf myItem Is String AndAlso _
myItem.ToString.StartsWith("'"c) AndAlso _
myItem.ToString.EndsWith("'"c)
I had trouble finding examples that weren't looking at a specific column in the DataRow. It looks like my code does pull back all the matching results - but I'm at a lose for how I can create a duplicate table/modify the values?
The only requirement is to not using a For Each; as I already know how to do that. I've gotten closer - but I still can't seem to create a new row or a new table.
My new approach hits a dead-end when I try to do this:
Dim MyNewRow As New Data.DataRow With {.ItemArray = myRemovedQuotes.ToArray}
The Error message I get says, "Error 1'System.Data.DataRow.Protected Friend Sub New(builder As System.Data.DataRowBuilder)' is not accessible in this context because it is 'Protected Friend'."

View 8 RepliesDateTimePicker: Selecting A Range Of Hours Within A Single Day Only
Sep 18, 2009I'm looking for a way to use two DateTimePicker controls to select a range of hours and minutes within one day. That is, to basically select a 'starting time' and 'ending time'.
I started with two DateTimePicker controls with the custom format of h:mm tt. I tried adding (on ValueChanged), a check that made the selected 'starting time' will become the 'ending times' minimum and vice versa, the 'ending time' becoming the 'starting times' maximum
However, that approach didn't seem to work -- I was still able to select 11.00 AM on the 'ending time' and 1.00 PM on the 'starting time'. I have a feeling that the current day of the timestamp has something to do with it (e.g. the starting time is of the previous day, and therefore is less).
I thought about changing to a combo box of preset half hour intervals throughout the day; however the minutes need to be more flexible than that...
UPDATE:
Dan's comment below answered this problem... This is the code I ended up with for reference;
Private Sub DateTimePicker1_ValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DateTimePicker1.ValueChanged

View 1 RepliesCheck If Int Is Within A Range?
Nov 4, 2009On my form i have a textbox that users can enter a value into, how to i check whether the value entered in the textbox is within the range bewteen two other numbers?
i.e
Top int is 10
Bottom int is 5
The user enters 7 into the textbox
I want to check that the value entered is within the top and bottom range, and in this case as the number 7 is between 5 and 10 the answer would be yes?
If the user had entered 3 for example, then the answer would be no.
The Top and Bottom Int's will be set at runtime by the value entered into another textbox so will differ each time the user uses the form.

Check If An IP Address Is In Range?
Mar 23, 2011Is there a way to check if an IP address is within a certain range without having to iterate through a huge range of IP addresses?

I could also do with this working for IPv6 for futureproof my code.

Multiple Datagridviews Cells Being Selected?
Feb 16, 2012VB 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

DataSet Has Errors In Multiple Cells After Fill Method?
Mar 2, 2012I am experiencing something very bizarre when I execute the Fill method of my adapter. I've been running this query for months and all of the sudden this is happening after I installed SP1 for Visual Studio 2008. For some reason several DataRows in 2 of the 3 tables within my DataSet have errors in them when I view them in debug mode using the DataSet Visualizer. Here is a picture of what I'm talking about
It does this to random rows. If I execute the Fill method the first time, rows (5-10) will have these errors. If I execute the Fill method again rows 12-23 are affected and so on. I have no idea what is happening here.
This is effected my DataGridViews, because they don't display any rows, because of the erros. I should also note that when I run the lines of code below in the Immediate Window it says the DataSet doesn't have errors.
?Me.ds.Tables("Current").HasErrors
False
?Me.ds.HasErrors
False
