String too long I guess!

I use a procedure to create a listbox that shows all the queries in a database, so the user can select a query to run.

In testing, I ran into error 2176, something about "The text you are putting in this field is the wrong size, it must be either 255 or 2048 bytes...."  (I'm paraphrasing there!)

I set the list box for ROwSource=ValueList.

The DB I was using had LOTS of queries, so maybe the list was too big.  Anyway to handle this?  I suppose, the string I build containing queries, I could split into 200 char chunks, and display them thusly....And why do some queries come up with wierd names that I can't see in the DB window (things like ~sqqryWhatItIs).

I would tend to think that the value list can support up to 255 charactors. Dumb question but are you separating the values with semicolons?

another way to try this is by writing the names of the queries to a temp table and then set the controlsource of the list box to the temp table.  see if it displays.

with temptable
delete everything

keep the list box hidden(visible = false)
create a table with 1 field
loop through your querydefs and retrieve the names
write each name to the table

listbox.requery
listbox.visible= true

A list box can display a maximum of 255 entries, and each entry can be a maximum of 255 characters.
The character length shouldn't be an issue, because I don't think a query name can exceed 255 characters either.

The strange "~sqqry" entries are probably temporary querydefs that Access creates beind the scenes to help run your code. You should be able to filter out this entries using an SQL expression (e.g: SELECT *
FROM MSysQueries WHERE.....)

Nice idea.  Yea, separated with commas.

You're welcome.

If you need any more help doing this let me know.  I was brief in the explaination but I hope you got the idea.
