Setting a textbox's controlsource in VBA on a report

Posted on 2001-08-21

Simple question,

I have an unbound txtbox on a report, we can call it txtValue.  In the report I want to take the values from three other txtboxes that are dynamically generated, sum them, and have that value displayed in txtValue.  I don't understand why when I write the code and I reference txtValue that it doesn't give me the option for controlsource.  I have the summed value, i just don't have a way to give it to txtValue so it can be shown on the report.

Please help

By the way, I'm using a recordset to get the values that I want for the other textboxes.

Try summing it in the report detail's OnFormat event.

Reports are a bit special.  In the way that controls and fields work together.  The approach is not to set the controlsource, but simply fill the control in with a value:

  Me![mycontrolname] = 1

  Would put a "1" in the control.  Replace the "1" with the rsult of your calculation.

How do I replace the 1 with calculation?

You said you had the summed value correct?  Just do:

 Me![mycontrolname] = <summed value>

 in the OnFormat event of the section where the control is located.

  or did I miss something?

Actually, I have five textboxes that are receiving values.  I'm just trying to get the total of the first three. I got the total by using a variable and looping it through the first three.  That's in VBA, but I can't use that in the expression builder.

My report looks like this:

Year1 ... Year2 ...Year3 ...Year4 ...Year5 ... 3Yeartotal

I don't have a running sum or anything like that. All of the year captions and values get their data from a recordset since they change depending on what the year the user wants to specify.

In that case there shouldn't be any need for coding in OnFormat event.  Just set the textbox's controlsource as an expression sum it up.

Then in the OnFormat, simply do:

 Me![year3Total] = Me![Year1] + Me![Year2] + Me![Year3]

for example (but you need to use your actual control names)
