Access Value In Named Range In A Worksheet?
Sep 1, 2011
I'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]...

Having 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?

I 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)

I have a table in an Access database named 'tblSubscriptions'. I need to check wether a user with a certain user id has any subscriptions but im not sure how i would go about it. The fields within the tblSubscriptions table are: User ID, Topic Code, Completed I'm assuming i'd need to use the following command: OleDbCommand("SELECT 'Topic Code' FROM tblSubscriptions WHERE 'User ID' = '" & Username)But i wouldn't know how to use an if statement to check whether the user has any subscriptions.

I've got a number of buttons in an 8x8 grid named cmd_A1, cmd_A2, etc all the way to cmd_H8.
I want to have a string that contains the name of a particular button, and then use that string to access a particular button.
1) Dim button_string as string = "cmd_A1"
2) Dim current_button as button = [the button named in button_string]
3) current_button.text = "♖"
How do I do step 2?

What I need to get done here is not a GUI, like the SQL Import and Export Wizard, which can be run from the SQL (2000) Enterprise Manager only, but a code that I can run from within the Visual Basic For Applications IDE from Microsoft Excel 2003, maybe in the form of a module, class or userform or a combination of all three. The best that I have come across so far, was a class that first checks if the worksheet is in a database formattable condition, then creates the database, if it does not exist, a table and then transfers the data from the worksheet to the table.
I have tried the Access 2003 TransferSpreadsheet method, but that does not solve my purpose, because I want to move the data from Excel to Access, starting from the creation of the database itself.

I have an Excel Add-In with a custom ribbon and custom buttons. I'm trying to get these buttons to insert different templates that I have created for our reports. I want these templates inserted into the active workbook, after the active worksheet.This code will add the template worksheet to the active workbook, but it is placed before the active worksheet:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As Microsoft.Office.Tools.Ribbon.RibbonControlEventArgs) Handles Button1.Click

I have been having problems getting the template worksheet inserted after the active worksheet.Here is what I have so far:

I get an error with the 'ws' aspect of this particular line: Globals.ThisAddIn.Application.Sheets.Add(Type:="C:Template File Name.xltm").WorkSheets.Add(After:=ws()) The error message states: "Interface 'Microsoft.Office.Interop.Excel.Worksheet' cannot be indexed because it has no default property."

I have the following code to select records from an access table based on a date range. The user is required to select a week ending date (Saturday) from a datetimepicker field.The date field in access is formatted as short.The values in the database range from 12/04/2009 to 2/05/2009. When I select datetimepicker as 2/05/2009 (i.e. 2 May 2008), no rows are returned. Following is the resultant sql statement:
show: Select * FROM Work_Time WHERE WorkerID =1001 AND (WeekDate >=#26/04/2009# AND WeekDate <=#2/05/2009#)
However, if I select datetimepicker as 25/04/2009, the correct numbers of rows are returned. Following is the resultant sql statement:
show: Select * FROM Work_Time WHERE WorkerID =1001 AND (WeekDate >=#19/04/2009# AND WeekDate <=#25/04/2009#)
Private Sub btnGetTSData_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGetTSData.Click
Dim dSelect As Date
dSelect = dtWkEnding.Value

I want to dynamically call form, but after the form is closed and reopen i got the error "Cannot access a disposed object named "MainForm"". I've been searching about this error and found out that basically i'm trying to access invalid control.
My question is how i can use the object again? I mean closing and opening form is very common thing to do, so it should be able to be accessible trough the run time. To give you better perspective [code]...

I have an MSAccess 2007 DB to record our employees Personal Days Off (PDO). Until now I have only had a form to record each single day taken. This results in time consuming repetitive entry when an employee takes multiple consecutive days or weeks off.
My database consists of two tables:tbl_PDO (to hold the Worker, DateTakenOff and TimeTaken) tbl_Employees (containing the Employees contact info, Name, Address, etc.) A form for Single date data entry with tbl_PDO as the record source and the following fields: (This is the original entry method one day at a time and works as it should)cboWorker(with Record Source tbl_Employee[Worker] DateTakenOff(ShortDate) TimeTaken (in hours) A form for Date Range entry with tbl_PDO as the recored source and the following fields: cboWorker(with Record Source tbl_Employee[Worker] StartDate EndDate TimeTaken (in hours) I have been trying to work with bits and pieces of code Ive found online to create multiple rows in a table based on a date range.[code]...

I want to create program in vb2008 express with ms access database. Can somebody help me so i can learn how to program using classes hard coded. I have learned vb6 before but it has a big difference on vb2008.
I have a database named "DATABASE" in ms access 2003 and the details are: Table :
EMPLOYEE(EmpNo, EmpName), DEPARTMENT(DeptID, DeptName), CATEGORY(CategoryID, CategoryName), SUPPLIER(SupplierID, SupplierName), ITEM(ItemID, Itemname), ITEMLIST(ItemListID, ItemID, ItemDescription), INVENTORY
[CODE]...
All the CAPITALIZED name are Table and all items inside the parenthesis are fieldnames. I don't know where to start on working on this RECORDS. I was able to understand visual basic 6 a bit, and i am trying to apply the coding to VB 2008 but all i get is errors. I am hopeless now and i need help to be able to start my programs. If someone can give me a sample code, i think i would be able to trace the line of code to be able to understand it. I am currently an inventory manager on the small company i was working with and i like to organize my record by using database.

I'm using vb in excel 2007 and need to work through a range or array, the size of which varies from time to time.
The examples of using range always demonstrate using literals eg "A1:A25"
How can I programatically determine the end of the range - ie up to where the cells value is blank
And then can I use a variable in the range statement - eg .[A1:Lastcell]

I have the following code to add a row to my worksheet... DashboardSheet.Rows(DashBoardRow - 1).Insert shift:=xlUp It does add a row but it also clears the row above where it was added. In my program I add a row then populate the row, add a row, then populate the row. Since each time I add a row, it clears the previous row that I just populated, I end up with all blank rows excep the last one.

Now that C# supports named parameters, I was checking to see if it was implemented the same way VB did it, and found that there is a slight difference. Take for example a library function like this:
public static void Foo(string a, string b)
{
Console.WriteLine(string.Format("a: {0}, b: {1}", a, b));
}
[code].....
The way VB does it requires much fewer instruction calls, so is there any advantage to the way C# implements it? If you don't use the named parameters, C# produces the same thing as VB.
EDIT: Now that we've determined that the extra instructions go away in release mode, is there a particular reason for them to be present in debug mode? VB acts the same in both modes, and C# doesn't insert the extra instructions when calling the method normally without named parameters (including when you use optional parameters).

I am very new to VB.net and for a project I am supposed to do some "outside research" and create a database. The database should consist of items (sports players) who have a number of different values (one set is physical: strength, speed, agility, acceleration) and preferably another (technical ability: ball skill, dribbling, shooting, etc). I want the database to classify these and give each traits such as "Power Shooter" if the shooting stat is upwards of 90, etc. I want to be able to bring up characters through this and also through named searches.
