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.

I am not a programmer, but have been tasked with doing this anyway! We are working on a research project that involves testing properties of different samples. I am trying to create a form that will generate a custom report based on what the user chooses. So, I have multiple text boxes and check boxes to allow the user to define the query parameters (e.g. composition of the sample must contain at least 5% component A) and choose what data they are interested in seeing in said report (e.g. show pH, color, but not melting point). I have successfully created code to generate the query, then generate a report based on that query, but the report defaults to column widths that are generally too big (for example, the pH column width is 3 inches, it only needs to be about 1). I would like to be able to fix this, but have not been able to figure out how. At the same time, some of these fields contain numbers that are averages of multiple test results, so I would like to limit the number of digits shown, and display them as % where appropriate. I started with just fixing the column width issue:
I have tried to make a collection of the fields that are included, then loop through the collection and set column widths, but cannot figure out how to identify a field with a variable:
If I know the field name I can do this:
Reports("ReportName")!FieldID.Width = 200
But if I have a collection of names, FieldNames, or a string VariableName, none of these work, giving me an error that FieldNames or VariableName is not a valid field in the report:
Reports("ReportName")!FieldNames(1).Width = 200
Reports("ReportName")![FieldNames(1)].Width = 200
Reports("ReportName")![VariableName].Width = 200
Is there a way to reference a field name with a variable?
Alternatively, I thought there might be a way to loop through all fields and set widths - this would involve looking up a column width for each field, which I thought to do by adding a key to a collection of column widths. But I cannot find a way to do that, something like:
For each Field in Reports("Report")
Field.Width = ColumnWidthCollection(Field)
Next
This hangs up on the Field.Width line, with "invalid procedure call or argument", which brings me back to how to reference a field name with a variable.
Any help would be greatly appreciated!
Try with:
Reports("ReportName")(VariableName).Width = 200
I am using Access 2013 and I am trying to create a chart report on one of my reports based on a table. There are about 30 fields in this table. The first field ID is auto number and there is another Customer ID which is set to number, the rest are all "long text" (such as name, review and etc) When I went to the form design and created the chart, at the step which it asked me to choose the fields I need, there were only two available fields - ID and customer ID - available, none of the rest popped up(like the customer name and other stuff)
Is there anything I did wrong? I recall I have made this happen in the old version. And I also realized that there is no pivotchart or table view options in 2013 anymore. Is this because the version thing please/
Thanks, any help and advice will be appreciated.
Do you really need more than 255 Characters for fields such as Customer Name? I think you need to change the datatypes of the fields you would like to include in the chart. Think about a field in a chart that used the max of a long text field.
From the MS Office website "In Access web apps, the Long Text field can store up to 2^30-1 bytes"
My guess is that access does not allow Long Text fields to appear in charts because of the most logic use case for charts, which does not involve the possibility of using a field that is THAT big.
Anyway, try fitting your data in short text fields. If that is too small, then here is a link to increase the size of your short text fields to 4000
In most word processing programs there is a multicolumn option that allows text to overflow from one column into the next. Is there any way to do this using two multiline textboxes or richtextboxes in vb.net?
I have a form that will display a varying amount of data in a textbox, anywhere from 1 to 250 lines. Right now the user can scroll, but I would like to allow the user the option to expand the size of the form, and if the form is wide enough, spill over into a second column to reduce the overall height of the form/reduce the need to scroll.
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
Why is the length for my longcomment field (defined as varchar(600)) only up to 255 coming from an Excel spreadsheet? The length of the value in the spreadsheet is over 300 characters and the field in the table is defined at varchar(600). However, when I select on that field in SQL, it is truncating at 255.
Thanks!
When an Excel files is parsed for import, only a certain number of rows are scanned to determine column size of the input. How you are importing the data makes a difference on what you need to change, basically you either need to override the detected column size or increase the number of rows scanned. Leave a comment with what import method you are using if you need additional help.
In Microsoft SQL Server Management Studio, you can change the size by going to the Tools/Option menu and opening the Query Results branch on the tree control. Then under the Results to Text leaf is the the “Maximum number of characters in a column” value.
