I am new to access and I need help implementing a Dlookup function to call the associated value from a data sheet. I know how to run a perfect Vlookup in excel to solve this but I am lost for access.
The issue is that I would like to automatically call the Book_ID when the Name_of_Book is entered or selected from the list in Student_Data. Please see attached images. This is the formula that I am trying is Book_ID:=DLookUp("Book_ID","Book_Data","Name_of_Book")

My goal is to create a matrix like shown on this picture from database values:
The object diagram is shown below. I'm using LINQ and Entity Framework Core.
So I want to get all Users and all Customers that are in database and if there is an entry in UserOrder table for user and order, display the user order value as value in matrix.
I'm then trying to use these values in a kendo grid.
Hope you understand what I was trying to explain, please ask if there are any unclear details. (I am unfortunately unable to embed images so they have to be included via a link).
Thank you
I have a table called "Subsidiary Companies" where I store the names of different subsidiary companies and their corresponding company logo images as an attachment in a table.
I have a form called "invoice" where I use it to generate invoices. Whenever I select a subsidiary from a Combobox, it will change the image attachment box on my form to the one corresponding to the company selected.
After I attach the image to the table it worked. When I closed my entire access program and went back to it, it doesn't work anymore even though I did not change any codes, settings or image path. I got an error instead, "Runtime Error 2220: Microsoft Access can't open the file image.jpeg".
Here is my code to select the attachment image based on the company selected:
Me.AttachmentCompanyLogo.DefaultPicture = Me.ComboboxCompanySelection.Column(1)
Not sure where it went wrong as I am not very familiar with Access, would appreciate some help, thank you :)
based on this statement: " When I closed my entire access program and went back to it, it doesn't work anymore"
that behavior would occur if you failed to also include the primary/foreign key cross reference value in the record. such that when you next go to select it - it can't be found because when you added the image/path it also needed the key value as a cross reference...
this is just a guess of course...
look directly at the table and see if this data is missing...
on a different topic; if you have only a small quantity of images the use of attachments is ok however if there will be a larger quantity then one should not use the attachments feature and instead store the image docs in a separate folder while putting the path to the image doc in a table.
I have a form where a user enters an Id into a text field, and I then I validate said Id on the server. If the Id does not exist in the system, I display an error. I do this using async validation. If the Id does exist, however, the server will return a record from our database. I want to use those values to auto populate other fields in the form.
How would I accomplish this?
I did some searching and the closest solution I found was this other question on StackOverflow. The thing is, I want to change the value after my asycValidate logic has succeeded. I don't think I can trigger the action creator from inside asyncValidate, and I'm not aware of a way to have asyncValidate trigger a callback from inside the form component.
I was able to get it to work, by following the solutions discussed in the following thread: https://github.com/erikras/redux-form/issues/442
Have just got back into coding in Microsoft Access, so it might be something stupid.
Situation:
Sqlite database linked to Access db via ODBC.
Have created a form which has bound controls from a table.
Due to the way sqlite stores dates, as text, I am not able to use the calendar picker. I thought easy I can create an unbound text box control, set the format to date and then I will have a date picker. Then in VBA just get it to change the value of the bound date control, which would be hidden.
Me.txt_Date_of_birth.Value = Format(Me.Txtdate_of_birth_with_calandar_control.Text, global_date_format)
It works it changes the value of the bound control (which for testing is not hidden).
But when I change records I am getting an error of
Write conflict. This record has been changed by another user since you
started editing it. If you save the record, you will overwrite the
changes the other user made.
From my testing it is being caused by this unbound control updating the bound control. Anyone know a simple fix?
And I would prefer not to get my data from a query that formats the text field into a date field.
And I can confirm that the error does not occur when I create an access table and try to update a bound control.
Try saving the record at once:
Me.txt_Date_of_birth.Value = Format(Me.Txtdate_of_birth_with_calandar_control.Text, global_date_format)
Me.Dirty = False
Does this table have a primary key? - in the eyes of Access - by which I mean when you look at the table in design view with Access.....
If not try adding that.
I am working for a hospital and must create a form which MDs can use to submit accounts of child abuse. I must use Microsoft Access.
I have created the form itself, but I must now create a way which information can be harvested from the form. For example, if the doctor inputs the age, where can I store this?
I know access works through fields, but not how to create them. Is it useful here to use excel?
Thank you.
Condolences on having to use Access :-) Been there, done that.
Access stores the data in "tables". A "form" is just a front end for entering or displaying table data. When a doctor enters the age, that field in the form needs to be linked to a column in the underlying table.
When you want to create a "report", you will first need to create a "query" that selects and sorts the data from one or more "tables". You can see the query results in a spreadsheet format while you are designing the query. Then you can create a "report" which is a formatted layout for the query results.
I would recommend a book like Access 2010: The Missing Manual to help you get up to speed on Access quicker.
