I'm using Access and VB for the first time, trying to develop an application for hobby use. I built and populated my database, and I'm building my first module. Unfortunately, one of the most simple actions is tripping me up. I'm attempting to perform an action only if a 255-character text field in a file doesn't contain data, but comparing it to " " or "Space$(n)" doesn't yield the actions I'm expecting.
View RepliesSimple, I'm sure, but I am having one of those days...
I just need to compare two currency fields and do something if the difference is greater than one cent.
Any help with that incredibly simple expression, please? :D
I am comparing the columns in two tables in a JOIN to see if there are differences. The columns, COL3 and COL4, are "Text" fields. They are declared as:
Field Size = 255
Default Value = "" (an empty string)
Required = No
Allow Zero Length = Yes
Indexed = No
I use the SQL comparator <> in my test... so ...
Code:
SELECT * FROM
Table_A AS Tgt
LEFT JOIN Table_B AS Src
ON (Src.Col1 = Tgt.Col1 AND Src.Col2 = Tgt.Col2)
WHERE Src.Col3 <> Tgt.Col3 OR Src.Col4 <> Tgt.Col4
I expected that where Src.Col3 was set to 0 (the string character zero) and Tgt.Col3 was set to the default of "" (a zero length string) that the query would return that row? It does not however? No doubt this is tied in with the old NULL string and Empty string chestnut?What is the best way to compare "text" fields in Access.
i am in a query and trying to use criteria box to get rid of any record that has a blank in the ItemDescrption column.
i have tried Not Like " *"
Not Like "*"
Not Like " "
with no success.
Thanks
Hi all- I'm creating an update query.I have a field [dateLastEdit] that is stored as text, I have to compare it to a date entered on a form by user [date_from] (I need to select all dates greater than this) but I'm running into problems:when I use date_from in text or date format and compare it to dateLastEdit in text format the comparison is made in numeric order(so 12/02/2006 is selected as well as 12/02/2005 when date_from is 12/01/2006)SELECT PTSData.LastEditDateFROM PTSDataWHERE (((PTSData.LastEditDate)>=[Forms]![chMgmt_frm]![date_from]));when I use date_from in date format and compare it to dateLastEdit converted to date format I get "expression typed incorrectly or it is too complex to be evaluated" msg.SELECT DateValue([LastEditDate]) AS Expr1FROM PTSDataWHERE (((DateValue([LastEditDate]))>=[Forms]![chMgmt_frm]![date_from]));[LastEditDate]'s format is always mm/dd/yyyy hh:mm:ss, but as text, not date data type.I've tried CDate with same results, isolating it in its own query to test it, using hardwired dates as criteria, but no joy, am I missing something obvious?forgot to add- I've used all the above with left also to select only date portion with same results
View 5 Replies View RelatedI have five address fields:
add_1
add_2
add_3
city
county
zipcode
What I want to achieve on my (Word) letters, forms, reports etc is a concatenated list that does not have any blanks!!
city, county and zipcode will always be filled however it is possible that add_2 and add_3 could be blank. I hope I am explaining this correctly?
How do I achieve this? I envisage a query which produces just one list that I can just add to my documents but I am struggling with the formula to ignore the blanks.
Anyway, here is what I am looking to do:
1.) Generate a random number between 1 and 100 and assign the result an identifier, like a person's name.
2.) Generate a second random number between 1 and 100 and assign the result a different identifier, like another person's name.
3.) Compare the two randomly generated numbers.
4.) Have the identifier of the LARGER random number displayed on the screen.
I would like to have this linked into a button click.I am hoping there is an easy way to accomplish this task.
I need to have the comparison variable (< or >) to be read from a field in the form.
Namely:
WHERE (((([PackagesCosts].[TotalCost]) & [Forms]![F_Reports]![Increased] & [C].[TotalCost])
Where [Forms]![F_Reports]![Increased] is the filed on my form.
What is wrong in the syntax (as it is not working properly)?
I am having a database in access and i want to highlight particular text from nearby column to the next column. For example,
--GCCCAGGCCCAAGAATGTCGCCGT GGAGGACTGTCTGTACATCAACGTGTTCGTGCCACGGCCCAGGCCCAAGAATGTCGCCGTCATGCTGT
GGATCTTCGGGGGTGGCTTCTGACAAGCTATTGTGTTCGAAT ACACTGATT
--CGAATGAACGCTGTCCCTTCCACTGCTGGCAACATGCTCCCAGCCTTCGACAATGGCCCTCAATTCGA
GGACTGGTTT CAACGAATGAACGCTGTCCCTTCCACTGCTGGAACTTCCGACTCCTTGTTGCCTAGAATGTCGCCGTCATGC
The first column text it should take as query and then it should only search the adjacent cell and highlight that. While searching in the internet i came across a code also, But i dont know whether i can use that code or not.
ALTER PROCEDURE [dbo].[Search]
(
@searchTerm nvarchar(100),
@style nvarchar(100) = 'font-weight:bold; background-color:yellow',
@maxLen INT = 100
[code]....
-How can I address the fields on my forms? I just want to create a button that increases a value by one on click.I tried
FORMNAME.FIELDNAME = FORMNAME.FIELDNAME + 1
FIELDNAME = FIELDNAME + 1
FORMNAME!FIELDNAME = FORNAME!FIELDNAME + 1
but the button does nothing. And that is all I found by googling.

View 6 Replies View RelatedThe database contains the records of a collection of thousands of photographs and negatives.
One of the fields contains information on the subject matter of each pic and can sometimes be very long. The field was changed from text to memo so as to hold more characters but they appeared in one long string, which means a lot of scrolling to see the information. That has been changed back to text and we are adding a second or third record such as xxx-xxx-xxx cont1 xxx-xxx-xxx cont2 so as to get shorter strings. Is there a way to make the text wrap onto a second or third line automatically after a specific number of characters have been entered or can a carriage return be put in to force the text to a new line?

I have
Table called "Products"
Field 1= "Product ID" which is a text field (PK) but numbers are used (ie 1 -20)
Field 2= Products -showing our list of 20 products
When I enter a new product, currently I have to look in the table to find the last ID used then use the next one available. I have created a form to be used for data entry to enter new products
What I am trying to do is :- 1, have the form open at data entry level but still able to scroll and see all records and 2, Have the form auto generate the next number available. For example, I have 20 products entered so when the form opens to enter a new product, the ID is automatically at number 21. I know absol nothing about coding. I have looked at other suggestions on the forum incl the DMAX +1 and having tried and not worked, I wondered if its because the field is a text field or I am trying to insert the code in the wrong place.

Encountered this bug in Access 2010:
1) Create a table with a single text field
2) Enter some text values, including one which begins either "aa", "AA" or "Aa" (but not "aA"!)
3) Sort the field, and note where it puts the string(s) created in (2)
For me, they appear at the wrong end of the sorted list! I have tested this in Access 2007 and 2010 and it only happens in 2010. I'm using 32 bit Access on 64 bit Win 7 Pro.
"The value you entered isn't valid for the field 'ID'.
For example, you may have entered text in a numeric field or a number that is greater than the FieldSize setting permits.
This error happens when i try to filter my results and select the topic I wanna search for. The field size is almost double what my longest field is. I am trying to do is from a table i used a lookup wizard to search that table for all the topics under that table.
I'm trying to concatenate two text fields into a memo field using an expression in a select query. My problem is that the text fields together end up more than 255 characters, so I need the resulting field to be a memo instead. I can't change the underlying text fields to memo fields because this is a large database used by others who need those fields to be text.

I have multiple fields in a table that are set up as Yes/No and display as checkboxes on a form. Now I need to create a text field on a report that showes all the Yes answers. The text field needs to figure out if it's a Yes answer, then display the field name, if there is more than one yes answer in the fields it is looking at, it should separate each with a "," . This is a large text field, that could show as many as 10 Yes answers.
What is the best way to go about doing this? I use Access 2010
I am creating a inventory database for work. I am trying to get the cursor to jump to the next text box for data entry using a barcode scanner. I have a limit on how many characters there can be in this field but yet even after it is all filled the cursor stays in that same field. I am fairly new to access, especially in code building. Do I use "After Update" under "Event" in the "Property Sheet"?
