Hi. Welcome to AWF!

Please correct me if I am wrong, but the way I see it in your code, you are requiring the user to enter a From and To dates for the search, is that correct? If so, what exactly was your question about? Are you asking how to make either From or To input dates as "optional?"

In my tasksearchformbycombobox i have kept search by date to and from and search by task category and %complete.

all the functionalities are working fine in my form but when i search by date it only shows me complete task and it doesnt show me incomplete task when i try to generate report using command button60.


Note: try search using command button 60.

i am tired trying to resolve this issue. in my query which generates report i have even included is null field but that doesnt work. please give me a workaround for this.

hi ashah08 (what is your name?

I'm not sure what to look at ... currently viewing DateSearch but you didn't specify a form. By the way, "Null" means the ABSENCE of a value ... can't show what isn't there. If you want to find Null, as well as values, that needs to be in the criteria

You could Have a look at my Task manager template There are a number of search forms maybe they will help you

Hi there,

Thank You for your prompt response.
My name is Akash

By null i mean i want to show fields as per my category.
my category consist of complete and in-complete task.

i am using parameterized query in which input for date search is through textboxes.
textboxes are dateFrom and DateTo

what i am trying to achieve using my report is to display both the categories complete and in-complete, when i generate a report through date search.

Form through which i am trying to achieve this functionality is named as tasksearchformbycombobox

My report is generated using Command button 60, this command button opens my report which based on query named " Copy Of TaskQuery22"

in my query i have included the functionality for date search using textboxes from from tasksearchformbycombobox but when i generate my report it only gives me values for completed task and it doesnt show me in-complete task.

in-complete task are those task where completed date is not mentioned.

Moral of the story - my date search works but it shows value where my datefrom and dateTo are enetered but if any of them are null or no values or field is empty then it doesn't show me on my report.

For Reference i am attaching my database please check


Please help me thank you

My 2 cents - I never use dynamic parameterized query because of complication of handling parameters when no input is provided. I prefer VBA to build criteria and apply to form or report. Perhaps MickJav template has examples of that but here is another source to review http://allenbrowne.com/ser-62.html

If you must use dynamic parameterized query, consider providing alternate values if user does not do input:

Between Nz([Forms]![TaskSearchbycombobox]![OrderDateFrom], #1/1/1900#) And Nz([Forms]![TaskSearchbycombobox]![OrderDateTo], #12/31/2199#)

Hithere,

Thank You so much for your prompt reply.
I have used vba only to display my records on form.

but frankly i am new to ms access and i am using it because i am asked to do so or else i would prefer something else.

I dont know how to create report using Vba?

I have my vba code to display all records on my sub-form and it works fine but when i had to create report i couldn't find any alternative other than using Queries

can you guide me on how can i create report using Vba?


Thanks once again !!!

I tried using this but output still stays the same.

Thank You

Yes @June7 It builds a where string which is used to limit a queries output.

VBA does not build report, it builds filter criteria and applies it to report when report is opened. You have been provided references with examples of that.

The report is a different question I thought we were dealing with the search problem?

I would suggest you download that template as It has a print screen as well the templates cover everything needed to get you going.

Hi @June7 ,

i tried this to display records based on filter on my report but it displays only first record from the database.

DoCmd.OpenReport "DemoReportSubform", acViewPreview, , "ID = " & ID.

Can you tell me whats wrong ?
i want to display all the records based on my search criteria from the form.

[ashah08]

it allows to download only 1 template per day and its not allowing me to download the template that i actually need.
