Hi all This post is an extension of the previous post ( how to develop a carousel ). Here I will show how to manage a summary form linked to a detail one, in order to show data and detail them. I want to clarify that this is not "the way" to work with access, this is "a way". This is the way I use. After been developing Access applications, I've found this is a good solution, and I use it almost always. I will improve the previous example, the used cars seller adding a new form. The new form has a listbox and some buttons (add, delete, duplicate and modify) to perform those operations. All those operations are solved using VBA, as you may see. The new form is named Main. You may see in the next screenshot I've added new records. Once the form is loaded, the data are stored in the listbox using the Form_load event. The objects are named as follows: Button Add is named cmdAdd Button Duplicate is named cmdDuplicate Button Delete is named cmdD...

Introduction Hi all! This week's post is a mix of part of the previous made practical. I will make grow the present example in following posts. We have seen how to organise an application, how to manage attached files, and how to work with options. This week we will join some of those characteristics to develop a Carousel. This is an example I've made some years ago to help a user with a carousel for used cars. It's made thinking on the spanish market, and I've used the plate number usual in Spain, that is, a number between 0000 and 9999 and three characters B-Z (avoiding the vowels). It's made with Access 2003. What is a carousel and when may be useful? A carousel is a form to show images, pictures, and when is loaded shows, automatically, a picture each time. In this case is each 5 seconds (5000 milliseconds). This may be useful, for example, in a business where you want to show photos of your goods to your customers: used cars, real estate..., that can...

Access is a powerful tool not only to manage data, but also to develop professional software. Due to its powerful structure, it is possible to work with it in some diffent ways, while the application grows up. For the rookies, I will expose, first, a brief of the objects you may find in an Access file. Objects These are the main objects and their meaning: Tables: where the data live. You may imagine them as sheets organised by rows and columns, where the columns are named fields, and the rows are named records. Each field has a data type, that is, all data contained on a field is always the same. Queries: these objects are very useful when you want to combine data of tables. Forms: to show and to enter data, those objects may contain text fields, check boxes, command buttons, text areas, list boxes, and other type of controls. Each form may have linked a module where to write code in VBA programming language for automate its behaviour. Reports: similar to forms, but only ...

Introduction Today I will explain how to do an Options dialog box with parameters for your application in MS Access. An options window is a simple dialog form. It may be linked to a table, but I prefer to do it using VBA, to have a more professional look and a very good maintenance. This post is organized in six steps: the table, the form, the records, the code in a module, finishing the form, and the code for the form. At the end of this post you may download a small Access file with the form options, the table and the code to manage it. First step: The table For the table, I usually create a table with three fields. The name of the table is Options: parName (text, 50, Primary key): the name of the parameter parValue (text, 50): the value of the parameter Details (text, 255): a brief explanation text field to have information about the field, like a comment. Later in this example we will see that there are different types of values, but the field is always a text fiel...
