Hi
Is it possible to change the default table setting in Access 2000 for the 'Allow Zero Length' property from No to Yes? Or does anyone know any code that can be run to change any existing fields with Allow Zero Length = No to = Yes?
Any assistance would be much appreciated.
Thanks.
in my db, all fields that aren't required default to a zero-length string.
In some reports (like mailing labels) I want the rows that contain no information (like the second Address line) to "shrink". I set all my properties to "can shrink" etc., but of course it's not working, because the value of the "empty" fields is "" instead of Null.
Is there a way I can write an IIF statement that will set the value of the field to Null if it contains a zero-length string?
I am trying to change a field lenght of a large database (access 97) It is at 50 right now and want to change it to 25. When I try to change it and save the table I get a error when the bar is about 3/4 the way accross the bottom.
Microsoft can't change the data type - there isn't enough disk space or memory.
then
not enough space on temporary disk
This is error 3183. In the help it says that the TEMP DOS enviroment variable location doesn't have enough space. (summerising). Now I have a 100+gb drive that isn't close to being full. I also changed the MaxLocksPerFile registry dword to 8,000,000 as my table has around over 3 million records. I have tried this on a xp and 2000 machine same results. Next I am going to try it on a 98 machine. I could do it by breaking up the table into 2 differnt ones and do each one individually but there is an autonumber field used as a reference number (I know I know). So that would screw up the numbering scheem (Yes I know there are ways arund that also). this database is about 400MB
Couple of questions
1. Is there a way around this? I have not found a solution on line yet.
2. Will lowering the field length make the database smaller (the data that is in there now is less than 25 charecters and the field is set to 50.) I have gotten mixed info on this. there are a few fields I would like to reduce.
Thanks

I have a continuous form that displays data from a table. What I am trying to accomplish is to change the format of the field if the string length is equal to 11, to "@@@-@@@-@@@@-@". Otherwise if it is greater or less than 11 then no format.
I have tried it using code:
If Len(Me.FormFieldName)=11 Then
Me.FormFieldName.Format = "@@@-@@@-@@@@-@"
End If
Is it even possible and if so is my syntax correct or am I way off base?
I have a report that prints labels (similar to avery labels) which pulls data from a query. These labels are all unique and vary in length. Due to the length variance, I want the font size to get smaller for labels with more characters. I want the text to go down to another line when necessary.
In my report under the OnPage Event Procedure I wrote this:
Private Sub Report_Page()
If Len(Text2) > 20 Then Text2.FontSize = 8
If Len(Text2) > 10 And Len(Text2) < 21 Then Text2.FontSize = 10
If Len(Text2) < 11 Then Text2.FontSize = 14
End Sub
This works to some degree but the problem is that once there is a longer label, all of the proceeding labels are resized & the longer label that should have been resized was not.
Is there another place I should be writing this code? I looked under events for the textbox but there doesn't seem to be anything that would work since none of them would trigger when printing labels
G'day,
I preface this question as most newbies do. I have just started using Access(2000) and have built rebuilt/converted from DOS a database for a basketball club. I did start from scratch and just inported the table data.
I have already made a number of forms and subforms, e.g. searching for a player displays all the other players in that team and displays the team staff from the relevant tables. So I understands the concepts.
What I have tried to do, and succeeded in part is to populate some of the fields of the Player Account records from the Fees table. I managed to do a query from the Fees table for this using a drop down for the FeeCode, which fills in the Fee Description and Fee Amount. However if I change the Fee Amount it changes all of the fee amounts for that Fee Code type. (I think I solved this myself as it is a query and that is what it should do, correct me if I am wrong). Note that all of the retrieved data is static except for the Fee Payment, which can be different amounts, this is where it changes the source. Also as it is a query I think , the retrieved data just shows on the screen and doesn't get written to the Accounts table (not the description though).
So I have obviously gone about this the wrong way and rebuilt the Accounts trying to use lookups. Here is my problem (finally you say). I cannot get the default value to lookup the fee table based on the fee code. Note I have not started on the VB side yet so please be easy on me. There is a drop down box for Fees Charged but this lists nothing, so like the query before nothing gets written to the Accounts table.
I think (maybe I don't) understand the lookup thing as I used an old (DOS) database before and did the same thing and was able to change the default value just for that account. i.e. lookup the table>field where the fee code is = to this. I have tried the subform wizard a few times but just cant get it right.
Should the lookup be in the table field or the subform. Am I on the right track and if so how do I get the retrieved info from the Fees table into the Accounts table. My end result should be something like this.
Fee Code(lookupFees - write to accounts), Description (lookupFees - display only), Fee Charged(lookupFees - write to accounts), Fees Paid(lookupfees - modify write to Accounts), Date(Accounts), Receipt Number(Accounts).
Thanks for taking the time to read this, I have tried to give as much information and hope I haven't given too much.

DrF :)
I am trying to set the default sort code to something other than the primary key. Example- Book Code is Primary Key but I want the table to be sorted by Title. I have went into properties and used the Order By property and typed 'Book.Title' however when I view the datasheet, Book Code is still the 1st column??? Is it still being sorted by Title??
Any help would be greatly appreciated
Hi Everyone,
I hope someone can help.
I have a form with a combo boxes and a table with relevant list and additional field, fldDefaultDrive (Yes/No Field).
Currently in order to set the default value, I have used the following code for each default;
Private Sub Form_Load()
Forms!frmMediaLabeller!CboDriveName.DefaultValue = """D"""
End Sub
However, I want users to be able to go into the table and change the default value if thier CD player default Drive is anything but D: Drive. I have tried to replace the D above with an SQL statement but with no success.
Private Sub Form_Load()
Dim Drivename As String
Drivename = SELECT tblMediaDrive.fldDrivename FROM tblMediaDrive WHERE (((tblMediaDrive.fldDefaultDrive)=-1));
Forms!frmMediaLabeller!CboDriveName.DefaultValue = """Drivename"""
End Sub
This is definetly not working, can anybody help, I have a feeling it is syntax but not sure where? :confused:

Um, well hi
I am a VB programmer, and need a database for a diary program i am making. Only i need more then 255 characters in one of my fields.
Is this possible, if not, what are my options.
Thank you

I have a fax number field iwhich has a mask. +(000)-00-000-000 in a table of many records.
The problem is that every record has a number in the first part of country code +(001)which must have come there by mistakes, few records have complete and true fax numbers.
I need a query that can Update this Fax_Number field where the length of the string is less than 7 digits.
Some thing like UPDATE Contacts SET Contacts.Fax_Number = ""
WHERE ((Len("Fax_Number")>"6"));
How can i do this. Thanks.
I have a field, integer, that needs to be exactly 6 characters long, no more, no less. How would I set this?:p

I'm looking for some advice on what the maximum field length is in Access. Which option will provide the maximum length. I am wanting the field to capture both numbers and text.
Any pointers in the right direction would be much appreciated.
Thanks in Advance.
What is the maximum number of characters which can make up a query?
Is it 255?
J-F
is there a way to allows more that 255 chars in to a text field in a mdb? or do i have to do something like save it to a test file then link to the text file (cos i really dont know how to do that :P)
View 3 Replies View RelatedI've notice a situation in a few databases. One is where we track sidewalk construction. There are two called fields LENGTH and WIDTH. In my report I have text box with the control source =[Length]*[Width]. However it returns some bogus number. If I change the field names to something else like Width1, it works fine.
Any ideas?
Thanks,

Would it be possible for someone to explain to me how to program a variable length text fields in a table, as opposed to a fixed length field?
Also - what would be the disadvantage of using this type of field ?
Thanks

Hello,
If I read the documentation then memo field in a Access table can be 65.000 chars long.
I have three memo fields in a linked ODBC table which is filled by a append query from SQL-server database. The text in these field is cut off by 255 chars.
Does somebody know what the cause of this can be?
1. Is there a limitation/property where I can configure the length of Access memo field? DAO? I have read something about this but I don't understand this.
2. How can I trace that everything is send from the source? Maybe it's cut off at the source site. On this moment I don't know something about a Linked tabel.
Is there a sniffer or trace tool so that I can see what kind of data is realy send?
Thanks in advance

Hi everyone,
I am using a table that stores data and one of the fields is just a text field with a maximum length of 10.
However, when I store the data in the field, if I only enter 5 letters in it, it stores the 5 letter word correctly but followed by some spaces (I assume 5 spaces but I may be wrong.
I cannot figure out why does anyone know why?
If not, then can I trim the field if I use it in a query/report?
Thanks.
Gareth.
All,
I am using an Make-Table query to add many new fields to a Table using Fieldname: "".
However, when I use this, it sets the Allow Zero Length to No.
Is there code that I can use to stop this happening?
I am using this method for multiple fields and across multiple tables.
Your help appreciated,
Jem
I have a query in which I need to pull all values from a field that is exactly 10 characters in length (Alpha or Numeric). Can anyone help me with this?
Thank you!
In a database that holds membership records, I have three years worth of info relating to membership dues paid. I want to extract who has not paid a membership fee for the last three years, so we can strike them off our records, i.e. I have members' personal details, but there are no records in the payments table, nothing has been entered because they just have not paid. Do I run a query looking for a zero length string? Just how do I achieve this? Have I done right in not entering anything?
Help appreciated!
I posted this before, but didnt get any answers
In A2007, has anyone had a problem with checking whether a text field is equal to "" in a query
ie - select * from whatever where targetfield = ""
-----------
this generated a type mismatch (I actually had <is null or ""> in the query definition, but it was the "" it didnt like.
I have written a bit of code in a Microsoft Access 97. The code basically creates a Microsoft outlook message. I am trying to add in the message that I want to display in Outlook by using the MyMessage ="" command. But the message I want to add is too long to fit on one line of code - I get to the end of the line and can no longer type any more! I have tried to add the second part of the message to the next line but all I get is an "Expected line number or label or statement or end of statement" error message. I think this might be because access keeps putting a " at the end of the first line - every time I remove it and add the " to the end of the second line it keeps adding it back to the end of the first line!
any ideas would be gratefully received!!!!!
I am using VBA code to export a small table as a .csv file, which is no problem, except that the customer insists that where a field is blank, the .csv file must contain a pair of double quotes.
In other words, I can produce this:
"Field1","Field2",,"Field4","Field5"
but they insist on this:
"Field1","Field2","","Field4","Field5"
In the table design, I have made the default for each field = "", but I still can't seem to force the double quotes into a blank field.
Any suggestions will be welcomed.
Hello and Good Morning,
I am trying to create a 5 page report filled with colorful tables, charts, and graphs. This report will need to be reproduced 115 times. I am almost finished with page 2 of 5. When I try to start page 3, it appears that the height of the report is capped.
I have reset my computer to clear my RAM, but I still have the same problem. I try extending the length of the report, but the window will not scroll down beyond 22". Is there a way to extend the height of the report?
Thank you in advance, and I will try to answer your question in return.
