    Calculating with Null Fields in a Query

    I haven't had time to really look into it yet, but I just found out there's a ' WHERE EXISTS' function in access that I didn't know about. I think this may hold the key to solving our problems, but like I said I haven't really looked into it yet.

    Calculating with Null Fields in a Query

    But wouldn't that only work for missing values in a field, and not for 'missing' records? Or am I mistaken?

    Calculating with Null Fields in a Query

    I think I have a very similar problem so I hope you don't mind if I explain mine in the same topic. I have a database that keeps track outgoing money per category, incoming money per category, and budget per category per year. I want to calculate remaining budget by calculating budget - (sum of...

    Copy record data to another table through form

    I don't think I explained the problem well enough, but by now I found the answer. I found out Access automatically selects the correct/current record when you place a button in the details section of a form. I assumed I somehow had to tell Access which record I wanted the data from so I was...

    Copy record data to another table through form

    Hi, Each table has it's own autonumber as ID. I'm not storing any 'real' invoice numbers because it's not for business purposes.

    Copy record data to another table through form

    Hi all, I have a form with 2 subforms, each based on their own table. One displays categories of invoices (e.g. rent, electricity, etc.) including some details like monthly costs. I would like users to be able to select one of those categories and copy this to another table, after which they...

    Problem exporting form to another database

    I'm currently in the process of pasting the controls and fields but it's a pain in the butt. I also seem to have lost the stacking property of my fields, so first I have to make them stacked, then change the padding between them, add a field, copy 3 controls back in and re-align them with the...

    Problem exporting form to another database

    Hmm, actually I just noticed something else keeps going missing: a few text fields that I added at a later stage than all the other text fields... the buttons were also added at a later stage... I can't put my finger on what's going on here. :S

    Problem exporting form to another database

    Hi all, I'm trying to export a form to another database. I've tried both simply copy/paste and using the export function. In both cases the form is copied to the other database, but my buttons go missing. Is there a way to move the form to another database and keep it intact?

    Cascading combo boxes working yet not working

    I think I finally just solved it myself. I was making two mistakes. First of all I should have put the fields with the details in a sub form rather than on the form itself. I already tried that before but with no results. The second thing I needed to do was give the sub form a 'where' clause...

    Cascading combo boxes working yet not working

    Do you mean that I shouldn't add more criteria as I go to the next combo box and then the next? So in stead of saying combo box 3 needs to take box 1 and 2 into account, it should only take box 2 into account? If that is what you mean, that does make sense and is good to know, but I don't see...

    Cascading combo boxes working yet not working

    Hi all, I'll try to explain this as clearly as possible: I have a database consisting of 4 tables, each containing items of a certain type. I also have a 5th table which is a join table, because different combinations of items have specific properties (e.g. 1 item is 50 cm long, the other is 60...

    DLookup without criteria?

    Hi all, I've never used DLookup before and I can't get it to work for me so far. I have 1 table which contains products and different properties of each product, such as the weight of the product. I have created a query which sums the weight of all products, but only for those that have a...

    Limiting order amount based on available stock

    Hi guys, Thanks for your replies. I'm taking it one thing at a time so first I'm trying to redesign my database based on Mihails advise. I'm wondering though with this new way of keeping track of transactions: how can I still keep track of which customer places which order, and optionally which...
