How To Dynamically Change A Data Type Of A Variable From One User Defined Type To Another
I have a situation like this. I want to declare a variable of a user
defined type that changes dynamically.
Like i have a user defined type called type1 and another called type2.
And i use

DIM var1 as type1

At later point of time i want the same variable to be declared to
type2. Use of REDIM is for arrays only and not for user defined types.
Is there any solution? Your suggestions would be of great help to me

Change Data Type
Hi all
I have a Access 97 table for which i need to change the datatype from text to number...I tried using code to do it but get the error 3219:Invalid Operation.

Is there any way I can do this? Cannot do it via "Alter table" statment either...

Code:
Public Sub ChangeColumnType()
Dim db As DAO.Database
Dim tbl As DAO.TableDef

Set db = CurrentDb
Set tbl = db.TableDefs("role_temp")
tbl.Fields("final").Type = dbBigInt

Set tbl = Nothing
Set db = Nothing
End Sub

Change Type Of RecordSet
Hi!

I open a RecordSet with dbSnapshot for viewing. After that the user can press an edit-button and then a save-button.

When the save button is hit, i want to create a copy of the recordset but it should be editable.

So i think i have to use dbDynaSet. So how can i copy a recordset and change the type as well??

Thanx for some help!

Change Data Type For Excel
Hi all,
I made a VB program that converts Excel to Access using DTS service from SQL Server. I usually copy an Excel file into my Excel template, save it and then convert it using this program. There's only 1 problem, if I paste the data from Excel file that contains number (which is not in 'text' format), my program assumes the resulting cell as null. I've tried formatting all cells in my template as 'text', but nothing changes. I've also tried to copy and paste-special ==> then only select 'Value', but still not work. Does anyone know how to solve this, so whatever I paste in my Excel template is in 'text' format? Thanks a lot!

How To Change Type Of The Cells In Excel?
Hello,

I have problem with getting cell values from an excel sheet which contains only numbers. Excel returns null, if the other cell values of the column contains text.
How I can solve that problem?
I tried some ways to solve that problem:
1. ALTER TABLE [Customers$] ALTER COLUMN Customer_Name CHAR(30);
2. UPDATE [Customers$] SET [Customer_Name]= '''' + [Customer_Name]
3. MAXSCANROWS=1;

First case failes with excel sheets, because Microsoft supports ALTER TABLE command only for databases.
Second case failes, with that simple reason SQL can't add char value to a number value (data type mismatch...).
Third case don't worked in my ODBC connection string, I think that's only works with text driver.

How To Change Type Of The Cells In Excel?
I tried to change type of the column in excel with SQL command: "ALTER TABLE [Customers$] ALTER COLUMN Customer_Name TEXT(30);" Result: Operation is not supported for this type of object. With MS Access table don't have problem, it's works. In the help of the MS Access I found the following text from Microsoft: The Microsoft Jet database engine does not support the use of ALTER TABLE, or any of the data definition language (DDL) statements, with non-Microsoft Jet databases. Use the DAO Create methods instead.
I want to convert all fields in the excel sheet to text type, because I have problem when I try to read trough ODBC cells which contains numbers, and it's type not set to text.

Thanks, Arman.

Change Table Data Type From Int To Varchar
I need to change the data type in a column in one of my tables from int to varchar. The kind of data that goes into this column is a 6 digit number. eg 217283. But now this column has to take other kinds of numbers eg. FIL78432. Is it safe to simply change the data type? Will the integer still work if its column type is changed to varchar? Is it better to create another column for this?Has anyone got experiance with this?
Thanks

How Do You Change A Fields TYPE And SIZE Values
I have an existing database that when opened needs to be automatically updated to reflect all the new field types and sizes from the new database. I have the routine built into my VB app that searches for any NEW fields and adds them to the old database.. but I am having a hard time getting the program to update the type and size of old fields that may have changed.
For instance.. what used to be just a text field now needs more than 255 characters of text.. so has to be changed to a memo field. How would I do this??
every time I try to change the type.. I get an invalid operation error.
Also note that the database does have data in it.
Thanks

Change The Connection Type, IP, DNS And Gateway Information Of An Internet Adapter
Hi everyone:

I have a laptop computer and I often move between home, work, university, etc. and in all these places the Internet configuration is different: another connection type and when I say connection type, I mean static IP address or DHCP. So I need to develop a program in wich I specify a profile (work, home, college, etc.) and the program makes all configurations for me.

So, I think I need to be able to set between Static IP or DHCP. In case the profile needs Static IP Address, I should be able to set IP Address, Subnet Mask, Gateway, Primary DNS Server and Secondary DNS Server as well.

The question is obvios: HOW CAN I DO THAT? Is there a way? Maybe some DLL or OCX control?
Maybe you know a freeware program that makes the same I'm trying to do. And maybe the program is open source so I can make some modifications.

Please any help.

Thanks in advance,

Andy
