What do I do if my Microsoft Access Combo Box won't let me change the values in it?
Is it bound to a column? if it is bound to a column, make sure that column can accept the value the combo box is providing. Make sure the combo box is enabled, too, and make sure that you have a valid record (that the form allows data entry) to input into. If your form isn’t bound to a RecordSource and you have a combo box with a query record source, there won’t be anywhere for the value to go to.
How can I store a data collected from an HTML form in Microsoft Access or MySQL?
Hey there,You can easily do it using PHP like Viktor said.First, you have to open a new connection:$server="localhost";$user="Username";$pass="Password";$dbname="DatabaseName"; $connection=new mysqli($server,$user,$pass,$dbname);if ($connection->connect_error){ exit("Cannot establish connection to database. Error cause:".$connection->connect_error);}Then you have to put your data into variables (you can use dynamic methods, this one is static):$data1=$_POST["YourDataHere1"];$data2=$_POST["YourDataHere2"];$data3=$_POST["YourDataHere3"];Finally you have to prepare the statement, bind the parameters (“sss” stands for “string, string, string”, change it according to your data type), execute the statement and close the statement + database connection:$statement=$connection->prepare("INSERT INTO
(YourDataHere1, YourDataHere2, YourDataHere3) VALUES (?,?,?)");$statement->bind_param("sss", $data1,$data2,$data3);$statement->execute();$statement->close();$connection->close();?>You can read some more examples on w3schools website: PHP Insert Data Into MySQL
How do I add a "select all" option to a combo box in Microsoft Access?
in an MS Access form or a user form in other applications, the list must be a value list, and have multi-select allowed to select all of the items in the list. The folllowing procedure will do the job:Public Sub ListBox_Selection_SelectAll(ByRef xListBox As ListBox) 'select all items in the specified list box control 'only selects all items if list is configured as multi-select Dim k As Long With xListBox For k = .ListCount - 1 To 0 Step -1 .Selected(k) = True Next k End WithEnd SubI would recommend that you go to my website and download the Tools and Utilities code library that I have published at this link: MSH Library - Tools And Utilities; an MS Access VBA Code Library by Matthew S Harris This code library contains a lot of code for working with list boxes, Select All, Invert Selection, and move items up or down in the list.
How do I use different combo boxes in a form to accept input to a field in a table in MS Access?
How do I use different combo boxes in a form to accept input to a field in a table in MS Access?Andy has a good suggestion, but his answer got collapsed.I will share another trick.If the ControlSource of a Combo Box is set to the name of a field in the Forms Recordset, it will Update it automatically when the User selects a choice.Another handy Trick for the properties of a Combo Box is :-ControlSource = “Sex”RowSource = “M”,”Male;”F”;”Female”;”U”;”Unknown”RowSourceType = Value ListBound Column = 1Column Count = 2Column Widths = 0, 2.5This will give the user a list of Male,Female,Unknownbut the Table Field will store M, F, or U
What is the difference between list box and combo box?
Let's start with ListBox. This box is scrollable and filled with choices. You select an item by clicking on it, and you can hold down the Control key while clicking Two important properties that you'll find in Visual Studio .NET's design mode are Rows and SelectionMode. Rows lets you specify how many rows of information should appear; you can define this as any number between one and 2,000 (the default is four). You can set SelectionMode either to Multiple or Single, which determines whether you allow the user to select multiple items from the ListBox.A ListBox is a container for a collection of ListItems. These ListItems can comprise a dataset bound to the ListBox, or you can generate it manually. For the demo code, I use manually generated data (and I freely admit that I cheated and used the Items property in design mode rather than generating HTML for the items by hand). A quick perusal of the HTML shows the value assigned to a list item is a property of the list item element, and the text displayed appears between the opening and closing spans of the element.A combo box is a commonly used graphical user interface widget. Traditionally, it is a combination of a drop-down list or list box and a single-line editable text box, allowing the user to either type a value directly or select a value from the list. The term "combo box" is sometimes used to mean "drop-down list".In both Java and .NET, "combo box" is not a synonym for "drop-down list" Definition of "drop down list" is sometimes clarified with terms such as "non-editable combo box" (or something similar) to distinguish it from "combo box".combo box:1. We can select ony one option from list.2. We can add info. at run time.3. We have only drop down facility.4. We can't use checkbox within combobox.List box:1. We can select multiple option from list.2. We can't add info. at run time.3. We have both drop up & drop down facility.4. We can use checkbox within listbox.
MS access help: Have a field auto-fill based on a combobox selection?
Joseph that was very helpful. Before i try, would the user be able to, hipothetically speaking, change the phone number of the employee, and store it in another Table, whilst keeping the original intact? In my database it makes sense because im dealing with default values and excentricities. I want the textbox to automatically fill a default value for a certain product after said product was selected AND let the user change it in case of any irregularity in the test.
How to Display an empty value in a combo box in a C# Windows application using MS Access?
Welcome to my very first article in Code Project! This is a very simple C# windows application that explainsof how to display a combo box without showing the first value in the database but an empty value. I was working on a windows application where I needed to display a combo box that would load with an empty field instead of displaying the first value in the table. I needed to do thiswith out physically inserting and empty field into the table that populates the combo box which is bad practice. Unfortunately as I'm still learning I was unable to find a good source on the internet that was able to help me. I can only assume this was because I probably did not type a key word or the article did not really deliver the information that I needed. I'm hoping my article will help those whoare also searching of ways to modify the way their combo box displays.

What is your opinion about using value list to populate a combo box in Microsoft Access as compared to using a separate table and query?
The most obvious problem with using a value list is that it is static i.e. the values are stored in a list that is not updateable easily. If you use a separate query to make up the list, you can easily create a way for your general users to update the list when they need to by making an appropriate form with the relevant controls. Anything where you lock the users into coming back to you for simple things leads to people resenting the software. Even if you end up being the person who does the actual maintenance of the list, you would thank yourself if you have used a table and query (that only you know how to access for example) rather than having to delve into design mode for a form and update the list there.
How do I delete Combo Box in Excel?
If you simply want to manually delete a combo box that has been placed on an Excel worksheet, it depends on how the combo box was created from the Developer tab. If the control was created by inserting a Forms control combo box, just unprotect the worksheet, if protected, right click on the combo box and 'Cut' (or press the DEL key). If the control was created as an ActiveX control, then access the Developer tab, click Design Mode in the Controls group, right click and 'Cut' (or press the DEL key).
How do I create multiple cascading Combo Box based on "Find a record on my form based on the value I selected in my combo box" in MS access?
Here’s a paper a colleague wrote which includes a sample database illustrating cascading combo boxes.The example is a list of species, both plants and animals, categorized by their taxonomic rank (kingdom, phylum, class, order, family, genus, then species).The solution involves adding code in the "AfterUpdate" event for one combo box, to update the RowSource property of the next combo box based on the selected value.Microsoft Access Form Cascading Combo BoxesHope this helps.
