Count Characters In Control In Real-time

Dec 9, 2005

Okay, seems like it should be simple... maybe I'm wrong though:

Any one know how to do real-time counting of the number of characters in a text box so that once it reaches 3 it automatically moves to the next text box? (Doing a phone number ... area code (int) and phone (long) to make for a total of 6 bytes.)

I've tried several versions of code for the on-change event but I can't seem to find the right way to assess the number of characters currently in the control... I'm pensive about setting an invisible control to just 'count up' because the on-change event would stack it even with a deletion. See most recent attempt below...

Obrigado,
~Chad

Private Sub txtAreaPhone_Change()
Dim bytCount As Byte
Dim strAPhone As String

If IsNull(Me.txtAreaPhone) = False Then
strAPhone = Cstring(Trim(Abs(Me.txtAreaPhone)))
bytCount = Len(strAPhone)
If bytCount = 3 Then
Me.txtPhone.SetFocus
Else
End If
Else

MsgBox "This is Null"

End If

End Sub

Display Real Time Now() Etc.

Aug 31, 2006

Detailed search cannot answer my time problem. Returning after long break in programming, I am trying to create a form to display TimeIn and TimeOut fields such that actioning an OnClick command (or separate tick-box), TimeIn field will hold current time for that record. Need to set the same for a TimeOut field. Both cases time always to be < 24 hours.

Am so rusty on MS Access putting default value as =now() produces an error!!
Any basic help to wind up the old mind always appreciated.

Getting Values In A Real Time

Sep 17, 2006

Hi:
I try to get the value in a real time. There are two subforms inside a mainform. First user enters value into mainform. Than comes to subform1. And after that on the basis of a choice in subform1, the 2nd subform is open. In 2nd subform i create a listbox with that query.

SELECT [tbl_Events].[PPVVOD_Outlet] FROM tbl_Events WHERE [tbl_Events].[ticketnum]=[Forms]![tbl_PPVResearch]![ticketnum];

But it shows empty. [tbl_Events].[PPVVOD_Outlet] is a subform1

Challenge: Real Time Queries And Lookup

Mar 4, 2006

Greetings!

Hoping somone could help me here.

I am trying to create a database (duh!). At the moment, I have two tables. One table is a small timetable with the fields:

Day, Airline, Flight Number, Time, Origin, Destination, Aircraft

The other table (Delay) has the following fields:

Date, Day, Airline, Flight Number, Time, Origin, Destination, Delayed by.

I would like to do the following. In Delay I put in the date: 01/07/2005, fine. The Day (field format Date/Time dddd) is also 01/07/2005 which Access transofrms into the word "Friday". Airilne is BA. In Flight Numbers, I want the database to do a query on "TIMETABLE" to search all flights that operate on a Friday as some do not operate daily. (By the way in the 'Day' column of Timetable the values are "Monday Tuesday Wednesday Thursday Friday Saturday Sunday" or "Monday Thursday Saturday" depending on the flight). This query/lookup should be performed right after I type 01/07/2005 in the "day" field of "Table: Delay". A lookup combo box should be displayed when I arrive at the field FLight Number. I select a flight (e.g.: BA001) and automatically the Time, Origin and Destination of the flight should appear in the "Table: Delay".

I have been unsuccessful at even getting past the first hurdle. I tried a query of the "Table: Timetable" and fields "Day" and "Flight Number". The Criteria I do not know what to put in. "Like [Delay]![Day]" or "[Delay]![Day]" does not help and brings up nothing. However, "Like *Monday*" does bring up all the flights which operate on a Monday. However isn't there some way of telling the query to automatically occur after I type in the relevant day in the "Delay" table? Futhermore I would like to avoid (but not totally exclude if it's impossible) macros as eventually I hope to publish this to SQL or whatever.

Cheers in advance.

Forms :: Check For Duplicates In Real Time

Apr 2, 2013

I have a form which im using to store records about companies that I have mailings with. The company name is my unique field as no two companies should have the same name. This form is accessed by several different people and data is input so I dont want duplicates of the company name being produced. Currently, the form wont save a record if it is duplicated but by then I would have filled out the entire form and wasted my time. Is there a way to do the following:

As I enter the company name it would look up exisitng company names. eg if i wanted to enter a new company called 'Dans Plumbing', I would type 'D' and below the text box would display a load of existing records starting with D. after that when I type 'Da' it would only display records starting with Da and so on. All being well, when I have finished typing the company name there should be nothing underneath so that I instantly know its not a duplicate and vice versa.

The possible duplicate doesn't have to be underneath it could auto complete IN the text box a bit like the address bar on a web browser.

Aug 15, 2006

I am trying to display a total based on 3 separate combo boxes in a form. there is a name with an associated number value using 2 fields. the values come from a linked value spreadsheet. the name field is "text" and the number is "number". the user selects their name and number using a combo box drop down window. this occurs 3 times in my form and i want to sum them in a 4th combo box. this is about how it should look, where "Total" happens automatically depending on the name selected.

Lewis 3 Smith 2 Parks 2 Total= 7

Forms :: Combo Box Where List Of Choices Are Narrowed In Real Time As You Type

Sep 29, 2014

I would like to create a combo box (or something similiar if a combo box simply can't do it) where the list of choices in the pulldown shows only the matches of what a user types in. The list of choices are coming from a field in a table. Also I would like the "search" of the user's input to include what is "within" each choice, e.g. if a user type "ber", then valid results should be bertha, october, robert.

Limit Characters AND Line Feeds In Memo Control

Mar 1, 2006

I have a data entry form with a memo control physically sized to match the allowable space for this information when printed on a report.

Basically, I need to be able to stop the user from further input when the cursor reaches the lower right corner of the memo control. Beeping when reaching the limit is acceptable, but a pop-up message would be ideal.

I have not been able to find a solution that will limit the amount of text displayed in the memo control that will also include however many LF's a user inputs. All of the search results refer to only limiting the number of characters and do not take into account LF's.

I am new to Access and would appreciate all suggestions.

Make Row Searches For Multiple Sets Of Characters At Same Time

Jun 18, 2015

I want to be able to make row searches for multiple sets of characters at the same time.The default setting cancels a row if I have inputed a set that is not on that row.Something that could be used in a store or by a lawyer looking for specifics.So these are what I am looking for:

Primary

1.) I want any row with any of the words I type to show on the results.

2.) I want the rows with the most matches to show up first.

Secondary

1.) Recognize sets of characters that are close to what I type to make up for spelling errors and typos, prioritize those that are closest.

2.) To be able to choose the rows I want and add them to another list quickly where the summing cost will be calculated in the last raw (multiplying the price of a row by how many the customer wants.)

Help! I Can't Count Time!

Mar 26, 2006

Hello,


I have been trying to get 'TotalMins' field to calculate to total minutes between 2 time fields 'StartTime' and 'FinishTime'. All the update queries i make only seem to adjust the underlying date. I have been advised that i will have to have both the date and times in the field,but this would reduce the simplicity of the form, i am using short date as the field settings.

I have also been told that as the finish time is occasionally past midnight ie. 0030 to a 2300 start time that this will also be a problem?

Any help would be appreciated!

I'm trying to generate a query that can be used for a pareto chart (Bar Chart shows the count of a defect and a line chart as a second axis counts the cumulative percentage)

I've grouped my data, and sorted the Count of each time the record appears but I cant get my head around working the cumulative percentage. My datasheet currently looks like this:

Reason Count Per Expr1
A 35 47.9 Random Numbers
B 11 15.1 "
C 10 137 "

Forms :: Login Form Time And Reset Count

Jul 1, 2014

I have a login form that closes automatically after a specified time if you do not login with user name and password. It also keeps track of how many times you login and whatever value you set for a password reset it forces you to change when that value is met.

Problem: If you do not login within the allotted time even though a password change has been scheduled, my code resets the login count back to 0.

This is what i want to get around if I can. Either I have to pause the timer or stop the reset.

After you enter the password is when the login count is fired.

And also when it checks if a new password is required.

Queries :: Count Number Of Tasks - Group By Date / Time In A Query

Aug 14, 2013

I want to count the number of tasks by department by week. I need the time so my date the task was added is formated as a date/time.

I created a query and added the department (twice so that I can group and count), and transaction date. I clicked on totals and added the count function under the department. I added this criteria to the task date: between [start date] and [end date].

Problem is that it's grouping by day and each one is different because all times are different. How do I group these by day and not time?

General :: Control Source - Set Value Of A Combo Box To Time Field

Oct 10, 2012

i have a list box with 6 columns. in column 6 there is a time field. on selecting this list box i want to set the value of a combo box to the time field.

so in the control source i put

[Forms]![frmAppointmentTreatmentItems]![comboTreatmentDuration]![Column](5)

This has no effect. I am not sure if i have done this correctly. but the combo box has manual values in it. the reason i want to have values in it is so if the treatment is 45 minutes at default. But i want to change it to 30 minutes just for a single occasion then i thought that this would be the way to do it.

Modules & VBA :: Web Browser Control To Navigate A Website That Only Allows One Session At A Time

Oct 16, 2013

I have constructed an application in Access2010 that uses the ActiveX WebBrowser Control.I am using the Web Browser control to navigate a website that only allows one session at a time and normally (if using a regular web browser) if you close the tab you're working on, you have to completely close the browser and reopen it to be able to acces the website again.

I have this application on 2 networks.

On PC

A) when using the WebBrowser control I can navigate to the site. But if I need to navigate away or need to log in as a different account on the site, I can close an reopen the form and that will suffice to regain access to the site.

However on PC

B) it will not allow me to navigate back to the site by closing and reopening the form (the website recognises it is not a new session). I have to close the entire database and reopen it to get the site to work again.

I would very much like PC B) to be behaving in the same manner as PC A) so that I do not have to tell users to restart the whole database in order to reaccess the site.

Modules & VBA :: Default Property For Control Bounded To Date / Time Field

Dec 4, 2013

Access 2007

In a table I have 2 fields:

D1 , Date/Time , DefaultValue: Date()
D2 , Date/Time , DefaultValue: Date()+1

In a form (bounded to this table) I have, of course, 2 controls bounded to this fields:

txtD1 and txtD2

If the user change the value in txtD1 (using the Date picker) I like to change the DefaultValue for txtD1 to the new date and the DefaultValue for txtD2 to the new date + 1 day. Something like this:

Code:
Private Sub txtD1_AfterUpdate()
Me.txtD1.DefaultValue = Me.txtD1
Me.txtD2.DefaultValue = Me.txtD1 + 1 day
End Sub

I tried whatever crossed my mind... with the same "result" : #Name?

My Regional settings:

Short date format: dd.MM.yyyy
Date separator: Dot
Simple: 05.12.2013
