what is the maximum size of data that can be sent from a text field on clicking the submit button?
I am asking this because the data in my text field comes up to be about 51KB. Will the whole data be sent to the server on clicking the submit button.
I don't think there is a limit on the data from a text area , If you want you can restrict the data using max length

What I need is a single text box where I can scan a barcode. Every scan gets saved to a column in the table.
Table
1-----2----3----4----x1----x2----x3----x4
123--123--123--123---23----23----23----23
where 123 is the barcode entered in the form, and the "x1x2x3" are extracted from the barcode entered in the "123" by calculated field.
I have the rest figured out somewhat but I can't seem to find a way to have a single text box to enter number to different columns.
To clarify I want help in the form section, I need help on where I can scan the upc code in one box and have data captured from that upc saved in a 1 column in the table and the next upc scanned will be saved in another column. How can I accomplish this thru vba or any other method. In the form I'll have a date and around 56 boxes where the scanned barcode will be saved for each boxes.
I have created a textbox and can put an infinite number of characters in it, I want to restrict that to only allow the user to type in 250 characters as this is the limit in my database.
I have tried myTextBox.MaxLength = 250
this will still allow the user to type in more than 250 but when I go back in it will only display 250 which means that some data after this amount is lost and the user might not be aware.
I am looking for a way to restrict any more characters from being entered after 250 characters.
The problem here was that I was limiting the size of the string being displayed on my form after I pull the data from the database when I used myTextBox.MaxLength = 250 when loading my form. here I was actually limiting the amount of text being displayed and not the amount of text the user could add.
by adding the code myTextBox.MaxLength = 250 when loading the component it now limits the amount of character I can type in the text box.
Good Morning All,
I am wrestling with a problem with continuous forms.
I have a continuous form based on a query that pulls transaction information from a table.
I want to have text box on each row where the user can override the fee value, at which point when the submit button is clicked the overridden information is written into a second table in the database.
When I add an unbound text box onto the continuous form I end up with all entries reflecting the amount I have just entered.
If I add a dummy column onto the SQL query, I am unable to edit the information.
Is there a way to do this? Below is an example of the form input I am shooting for:
Snip:
I don't think this can be done in Access.
I think the closest you can get, is to display the value from the secondary table in your continuous form; and then, after some user input (focus into the textbox, or double-click the text box, or button click), prompt the user to enter a value using either the VBA InputBox function, or leveraging the built-in Zoom box. Check that the user-entered value is a valid number, update your external table, and refresh the query results.
You might also create a custom form to validate the input.
I'm new to MS ACCESS, I would like to know if there is a way to clear an auto number field using a clear button. I've tried to follow some videos on you particularly this one but it seems to be not the proper way on how to deal or create an auto number field.
This is the image is the sample of the form which I'm experimenting with this particular subject.
And this image is the error code which I'm getting right after I clicked the clear button.
[![enter image description here][3]][3]
Below is the code I use for this experiment.
You don't need to clear autonumber field, it handled automatically. So, remove EnployeeID field from INSERT statement and delete rows with Me.txtEmployeeID from clear procedure
The AutoNumber Data Type is assigned automatically and can't be
changed. Also once you enter data into some other field like Employee
Name(New Record event initiated), access will assign a value to the
AutoNumber let's say 1. If you press Esc, access will cancel the edit. Next time you create a new record access will assign the value 2 and so forth. Unless you repair the database then access will reset the AutoNumber counter.
If you want a data type that you change its value, you need to change the Data Type to Number. In this case you need to assign each value by code or by the user input.
Out of the box SSRS reports cannot have data exposed in the page header. Is there a way to get this data to show?
One of the things I want in my reports is to have nice headers for my reports. I like to have a logo and the user's report parameters along with other data to show to give more information for the business needs the report needs to clarify. One of the things that Microsoft SQL Server 2005 Reporting Services cannot do natively is show data from a Dataset in the header. This post will explain how to work around this and how easy it is.
Create the Report Server Project in the Business Intelligence Projects section and call it AdventureWorksLTReports. I use the AdventureWorksLT sample database from CodePlex.

Next show the Page Header by right clicking in the Report area with the designer.

The Page Header will appear. If you want to show the Page Footer this can be accessed from the same menu as the Page Header.

I created a stored procedure that returns data for the Sales Order to be presented in the Page Header. I will show the following information about the Sales Order in the Page Header:
Order Date
Sales Order Number
Company
Sales Person
Total Due
I create a TextBox for each of my data fields in the Page Header along with a TextBox for the corresponding label. Do not change the Expression in the TextBoxes that you want the Sales Order data in.

In the Report Body, place a TextBox for each data field needed in the Page Header. In the Visibility for each TextBox, select True for Hidden. This will be the placeholder for the data needed in the Page Header.

Your report should look similar to the screenshot shown below.

The last step and most important is to reference the Hidden TextBox in the TextBoxes located in the Page Header. We use the the following Expression to reference the needed TextBoxes:
=ReportItems!.Value
Your report should now look similar to the following:

Your Report preview should now have the Sales Order Header data in the Report Header.

You have to do it through Parameters. Add a parameter for each piece of data you would like to display, then set the parameter to Hidden. Then set the default value to "From Query" and set the Dataset and Value field to the appropriate values.
I think the best option is creating a internal parameter, with the default value the field of the dataset you want to show.
Here are two possible workarounds:
You can place the databound field within the body of the report as a hidden textbox, and then in the header place another textbox with it's value pointed at the the one hidden within the body.
Try using report parameters to store the data, and use those parameters to access the data in the header.
This technique wouldn't work if your report spans over multiple pages, use queried parameters instead, and set the textbox value to =Parameters!Name.Value as per this article.
I'm with Orion Adrian here. Report parameters are the way to go.
I wanted to show a field, common to all returned rows, in the header, and for this scenario I went for the linked table solution (placing a table containing the field in the body and link a textbox in the header to this table).
I did that because if you are using the parameter solution and no data is returned to the field in question, the text "Parameter is missing a value" is shown instead of just a blank table. I reckoned this text would confuse users (as the parameter isn't even visible).
