I know that I can use an Alter Table query to add table fields from code.
But what if I just want to change a field from being Required or Not Required, or perhaps change the field width of a text field?
How do I do that from VBA?
I want to create an attribute called "order_line_price", which is basically the quantity field * the cost per product.
I have written the following SQL query which works fine:
SELECT Order_line.order_number, Order_line.product_number, product_name, quantity, (quantity*price) AS [Order line price]
FROM (Order_line INNER JOIN Product ON Order_line.product_number=Product.product_number) INNER JOIN Price_band ON Product.price_band=Price_band.price_band;
I can create a table from this query, and all is ok. However, I want to store the value of each order_line_price next in its appropriate row in my Order_line table. I cant do this no matter what I try. I know that what im trying to do is store a derived coloumn, however I need to do it, because I have an attribute elsewhere which is the SUM(order_line_price), which I want to limit by specifying the order_number for which to add the order_line_prices up for.
So basically, how can I store a derived column like that? I guess I need to set something up in the default value property and lock the coloumn or something?
Ive posted here before, and havent had replys. So if your reading this and dont know the answer, but do know the link to a forum or chat room with speedier replies, please post the link.
Thanks.
Hello,
in my Access database there is quite a bit of VBA code.
I have set my LAN and file path in some of this code but will need to change it when this database will get to other users using a different LAN and path.
Is there a way I can avoid them to open the code and manually change this information?
I was thinking of some sort of text box where they will write their path (ex. \S01000sharedoffice*.*) and use a cmdbutton to overwrite the existing path?
Thanks.
I am trying to set the default sort code to something other than the primary key. Example- Book Code is Primary Key but I want the table to be sorted by Title. I have went into properties and used the Order By property and typed 'Book.Title' however when I view the datasheet, Book Code is still the 1st column??? Is it still being sorted by Title??
Any help would be greatly appreciated
This is getting into some stratospheric territory for me.
I am trying to change the visibility property of a label and corresponding text box, based on the contents of a different combo box. cboHow is a combo box that uses a value list as its row source, since the content of the list won't change. There are three fields that I need when the content of cboHow = "FIS". Otherwise I don't need them and I don't want to see them. My code is below:
Private Sub txtFISDepartmentNumber_BeforeUpdate(Cancel As Integer)
If cboHow <> "FIS" Then
lblFISDepartmentNumber.Visible = False
txtFISDepartmentNumber.Visible = False
Else: lblFISDepartmentNumber.Visible = True
txtFISDepartmentNumber.Visible = True
End Sub
At the moment there is no error code, but the label and text field don't respond by becoming visible/invisible when the contents of cboHow changes. Do I put this code with the txtFISDepartmentNumber or in cboHow? and do I use BeforeUpdate or AfterUpdate? Should I have a separate If..Then..Else for the label and the text box?
I have been playing around with this for several hours now and seem to be going in circles.
I am using A2K

Is there a way to change the vertical scroll bar position to always be at the top when I move from form to form. Right now, it will start at the top, but when I move to a different form and back, the vertical scroll bar is positioned in the center. I turned off the autocenter property of the form and saved it in the desired position, but that doesn't work. My form is maximized when it opens. I would greatly appreciate some help. This has been an annoyance for quite some time now.
View 1 Replies View RelatedI'm changing a record source on a form when the user clicks a "save" button.
I'm doing this to store a value from the current form in a table that is not part of the default form query.
This works fine.
I have a separate button on my form called "Home", when the user clicks this button it requerys the current form which triggers the before update event to run, this in turn brings up a message box which asks the user if they want to save or not. If they click yes then it runs the SaveButton click() code.
For some reason when the user presses the save button and then exits, everything works but if a user presses the “home” button which triggers the save button then it brings up the “2107 The Value you entered doesn’t meet the validation rule defined for the field or control.” Runtime error and stops on the change recordsource command.
Why triggering the same code directly from a button or indirectly from a before update event has two different outcomes.
I have a tbble with attributes
'image_data','resolution','created','file_size'
At the moment i'm sotring the 'image_date' as an OLE object datatype. Is there anyway that i can get access to automatically populate the attributes 'resolution', 'created' and 'file_size'? or could this be done using a different datatype for the 'image_data' itself?
PLEASE help, it would be SOOO much appreciated.
Thanks

Hi,
I was wondering if anyone might be able to help me here. I was trying to write up a technical report for the Access database i built. Are there an easy way of exporting all the tables with their attributes in Access?
For example, in the student table,
ID
FirstName
LastName
...
Thank you in advance
I have a DB with about 50 tables. I have arranged them in a particular order in the relationship viewer and would like to print out as much of the viewer as I can by choosing the paper size and/or setting a scale factor. Access does not appear to let one do either. When looking at the relationship page, the 'page setup' under File ->Pagesetup is grayed out. Selecting 'print' causes the relationships to be printed in some sort of predefined manner, on 81/2x11 pages. Is there anyway to control how this view is printed?
On a related note: When in the relationship viewer, the only way to scroll the view is by the margin slider bars (the mouse wheel does not work). SHould the mouse wheel do the verticle scrolling? Also, if I want to move two or more tables (at the same time) in this view, how can I select them?
Thanks

I'm creating a database of companies. Every company has at least one field of services they provide. There are three main groups which contain all the services (Let's say I have three tables).
What I need is to have a form/table (query?) where I can assign to a company any number of services from any group. Is it possible to do it in a form where I could simply add a service by choosing a group first and then a proper service, and then add more in the same way?
hello,
Recently I have started working for one of the company where I have to deal with one of the access file. this file has lots of tables containing many fields.

This might be simple but I just can't figure it out.
I have a table that has a number field. Everytime I enter the number 1.50, it changes to 2. I would like to keep the 1.50. Somehow, I can't get this right. Is there a setting that I have to change? Would I need to make setting changes on the form portion also?
thanx for any help
Help needed: Large Yes/no tables!
I have a form with names of employees, and different skills that employee has.
It is listed in a form as columns with the employee name in rows, and columns for the skills. The form is in fact really great, but I see that the solution might bring problems in the future because of maintainance issues, and field limitations. I add fields frequently, and the table is growing without me beeing able to control it.
I have organized this in only one table, and used the name of the skill as a field. There is many other tables in the DB, but none of them covers this area.
exampletable:
employeeID | auto
employeename | text
Hireddate | date/time
Fireddate | date/time
baking | yes/no
cooking | yes/no
driving | yes/no
juggling | yes/no
With this solution I get the skillname as a heading, and the name as a column with lots of yes/no values. I love the filter functions, and the form is quite nice...
exampleform:
Employee baking cooking driving juggling
employeeeID1 yes no no yes
employeeeID2 no yes yes yes
employeeeID3 no no yes yes
employeeeID4 yes yes yes no
and so on.
Is there a way to organize this so that the skill name comes in the top row, the results get listed as shown above when the skill is placed as a field value, not a field itself?
I have looked for a solution with many-to-many relations with 3 tables, but cant seem to make it work right. It is especially the form I have trouble creating with the new design.
I have also tried to make crosstab queries with minor success.
Does anyone have a suggestion on how I can make the relations work.
One employee can possess a great number of different skills, and the skill can be possessed by a great number of employees. This is not a difficult issue by itself, the problem is to make the form as shown over.
Thank you, in advance.
Hi All,
I have built queries based on tables. The field names are the technical field names of an application. For example pernr is actually Personnel Number etc.
My queries are set up as follows:
Field = pernr
Table = etc
I would like to rename pernr to Personnel Number so that the column heading in the datasheet view is Personnel Number.
I know I can do this manually for each query by using the following as the field: Personnel Number: pernr
Is there any way of getting this be done dynamically using a lookup table etc. I have lots of queries and I don't want to manually change them all. Furthermore, if I wanted to rename Personnel Number to Personnel No. then I could do it in the mapping table rather than in all the queries.
Thanks,
Evan
Hello,
I have a form that I need to modify. Currently, the field list shows Query 1 as the 'control source' for the text boxes on the form and I need to change to use Query 2 but I am unsure of how to do this. Do I have to delete the test boxes and start fresh or can I change the field list and use Query 2 as the source?
Thanks for any help.

I have a property form for keeping track of houses and buildings owned and then on that form i have a policy field for the policy number of the insurance called txtPolicy. Next to that field I have a little button which opens a form so it will show all the insurance policies associated with the housing group which the property is in. When i select the appropriate policy and double click it in the listbox I want it to close the form and set the value of the txtPolicy to the one just selected in the listbox. I know how to get the value of the item selected in the listbox but I just don't know how to set the value of a field on another form...
