The database response is significantly slow when our application requests data over a network. Are there any settings to adjust network response? The network is connected via a T1 line.
According to information I've found online, our application is the front end to the database and the database sits open on the server.
Hi
I have developed a DB for work and it has grown, it is about 60Meg, all of a sudden when I am opening Design View in Reports, or queries it started running really slow.
I always Compact on Close
I have Split the DB.
Still no Joy, I have a brand new Dell PC so nothing wrong there.
What is happening? it is a nightmare to get anything done.
Please advise.

I have a front end that is connected to three back end files. The front end is on my local computer while the back end files are on a network drive.
There are a lot of calculations that go into the queries and intermediate queries. For a report, I have based it on a UNION query.
But when trying to design the report it takes about 45 seconds just to do any one thing, e.g.;
- Add Groupings
- Add Grouping Headers//Footer, sorting option
- Add bound textbox
:eek:
Needless to say this is very annoying.
:mad:
The union query itself runs fine (takes about 15 seconds to run) and returns about 12,000 Rows. The union query looks like this (I changed the field names to make it read easier, hopefully);
SELECT a1, a2, a3, a4, a5
FROM qry_A;
UNION SELECT ALL a1, b2 AS a2, b3 AS a3, a4, a5
FROM qry_B;
UNION SELECT ALL a1, c2 AS a2, c3 AS a3, a4, a5
FROM qry_C;
UNION SELECT ALL a1, d2 AS a2, a3, a4, a5
FROM qry_D;
UNION SELECT ALL a1, e2 AS a2, a3, a4, a5
FROM qry_E;
UNION SELECT ALL a1, f2AS a2, tblG.f3 AS a3, tblG.f4 AS a4, a5
FROM qry_F;
One solution I came across when searching the forums was to use an Append Query to append the query results to a table and base my report on that. This does indeed fix the problem.
But what I was wondering if it was is my query design that is causing it to be slow or is it just the fact that I am returning 12,000 rows?
:confused:
In case it matters, I wanted to mention that I can’t use the report wizard to create the report. When I select the union query, the fields will be showed for awhile then they just disappear. That in and of itself doesn’t cause any trouble since I am creating the report using the design view and not the wizard.
Hi, All--
I am designing a database to capture the data of returned surveys. I want to design the database to facilitate data analysis through crosstabs or other aggregation queries.
If I design a table where each record is the complete survey responses to all survey items in a returned survey, this is not friendly for such query analysis. (In this, each field would be a survey item). Call this the horizontal method.
The other way would be to have a reference table containing the survey items , and have responses entered in a seperate table linked by item id and response id (from a third table containing a record for each submitted survey). Call this the vertical method. This would take more time to set up but would probably be easier to query.
The item response table would become quite long contaiging every item response for every survey turned although each record is short.
Does anyone have any opinion on this, or perhaps a completely different approach that I haven't thought of that would be easy to set up but also easy to query?
Thanks.

Will archiving older data improve response time of a database?
What is the best way to archive data knowing that older records will still be accessed twice a year?
Hi,
I have a database for booking equipment in and out.
I have the backend stored on a shared drive on our LAN, and the front end on each client machine.
The database has been working fine until just now, it runs very slow and my DCount functions have stopped displaying data.
I have no idea why this has happened, please help?
This problem is driving me nuts!!
I`ve just spent a fair few months creating a database to be used by our sales team, I`ve about finished it and came to trial it with the sales manager. When he is using the database at the same time as me it becomes slow.
The design has a front end with all the queries, forms etc and a back end on a server containing the tables.
The database was created using Access 2000 and was designed to replace a similair db created on 97 which has a decent speed on the network.
The other strange thing is that one particular macro that I`ve been using for the speed tests runs quite slow (about 3 secs) when 2 pcs have the db open but once the macro has run if it is run again it takes typically less than a second to run.
What would cause a db to run a macro at different speeds after they`ve been run once? I`ve tried everything I can find on the net to try and improve the speed to no avail.
Help please!!
Hi everybody,
I have an access database which is around 40 MB after compacting it and I feel that it is slow especially when I open cross table form. Is there any way to speedup the databse.
Note: my databse is on the share drive in my work.
I have two databases, one is much larger than the other, but both have the same start up code. The larger database opens quickly, but the smaller database takes forever. I tried compacting and repairing the front end and the back end of the database, but that did not help. Any ideas on how I can speed this up?
View 4 Replies View RelatedMy database is opening much slower than normal just over the past few days. When I run a performance analyzer it is telling me that my database is only being compiled in a partial state. How did this happen and what do I do to fix it??
Thanks...
I am new to access.
On occasion my access database all of a sudden begins to operate very slowly, I notice the queries take a much longer time to run.
Last week it suddenly began to operate very slowly after idling in excess of 30 mins
Today when I change the screen to design view and then back to form view once again it begins to operate very slowly. (yesterday was working fine on my desktop at home, I have not made any changes to the database with exception to saving and using the file this morning on the shared drive at work) If I shut down and re open it operates well but once again changing to design view causes the same issue. Sometimes compact and repair rectifies sometimes not.
I recall reading somewhere (fairly recently) about a parameter or property in Access which is "On" by default and allows a form/query to identify when backend table field names or query arguments are changed and automatically looks for and "fixes" the renamed link. By leaving this switched ON, the database is slower than it could be. The db speed performance can be can be improved significantly by switching this 'feature' off. (i.e. Name of the property)
View 3 Replies View RelatedHi All,
I'm having trouble with access. Basically it has been very slow to load
(over 30 seconds when not opening a database) and when opening a database it just crashes.
Has anyone any idea what could cause this as it worked fine before ?
also would a reinstall help ??

I have a database which tracks onsite and offsite files. I need to create a pop up message box using the toggle button function, with a "yes" or "no" response, so when a file is onsite and you click the offsite box, a pop up message box will display the following message, "Are you sure you want this file offsite?" and if yes is clicked, it will switch to the offsite field. If no is clicked, it stay as is, (onsite would be the default). The same thing applies for when a file is offsite and you want to return it onsite, when you click in the onsite box, the pop up message box would display "Are you sure you want this file onsite" if yes is clicked, it will switch to yes, and if no is clicked, it stay as is. Can this be done?
Thanks!
In my database I have many names in alphabetical order. What I want to do is create something where, for example, if I type a 'B' in a text-like box the list of names from the database automatically scrolls/moves to the beginning of the Bs either in table view or preferrably in another text-like box that mirrors the table contents. Then if I enter an 'E' after the 'B' the cursor moves to the beginning of the names with 'BE' in them, and so forth for each additional letter. Each move would happen immediately after each key is pressed, without using the <enter> key, probably like a 'keypress' event.
I would appreciate some direction or if someone knows where there might be some existing code or examples.
Thanks ahead of time for your effort!!!
Looking for a way to supress this message box...
The text you entered isn't an item in the list.
Select an item from the list or enter text that matches one of the listed items.
... when the NotInList event fires.
Trying to just open an unbound modal form, pass a couple values to it, and set focus on a particular combobox for additional information to be added to my lookup table:
Private Sub cboPostalCode_NotInList(NewData As String, Response As Integer)
On Error GoTo Err_ErrorHandler
Const Message1 = "The postal code you have entered is not currently on record."
Const Message2 = "Would you like to add it?"
Const Title = "Unknown Postal Code"
Const NL = vbCrLf & vbCrLf
If MsgBox(Message1 & NL & Message2, vbQuestion + vbYesNo, Title) = vbYes Then
DoCmd.OpenForm "frmPostalCode"
Forms!frmPostalCode!cboCountryID = Me.cboCountryID
Forms!frmPostalCode!txtPostalCode = NewData
Forms!frmPostalCode.SetFocus
Forms!frmPostalCode!txtCity.SetFocus
Else
Me.cboPostalCode.Undo
End If
Exit_ErrorHandler:
Exit Sub
Err_ErrorHandler:
MsgBox Err.Description, vbExclamation, "Error #" & Err.Number
Resume Exit_ErrorHandler
End Sub
Any thoughts?

I have an 18.8MB Access application consisting of the following:
140 tables
410 Queries
67 Forms
5 Macros
26 Modules
It's not a lot of data storage, but is very computationally and mathematically intensive. As we continue to develop and expand the application, I noticed last week that we suddenly experienced a massive falloff in performance. Access is taking an incredibly long amount of time to traverse the querydefs collection, find objects, etc. It seems that the object collections themselves are not indexed, meaning that it takes a much longer amount of time to run a compiled and saved query than it does to simply build the SQL string and execute from within code. I continue to hunt for coding bottlenecks and any other efficiency problems I can find. Has anyone else experienced this? Is there a "critical mass" for the object containers?
Here's my crosstab report
Answer Name1 Name2 Name3
Yes 90 95 85
No 10 10 35
Total 100 105 120
I need to devide the number of Yes responses for Name1 by the total number of responses. I tried doing it like this =(([Name1]=Yes)/sum([Name1])), but that isn't working.
Thanks in advance,
Dave
I have a table of issues (tblIssues). Each issue has legislation that it must be dealt under. Some issues relate to more than one piece of legislation. Some legislation deals with more than issue. Ideally, therefore, I'd like to have a separate table of legislation (tblLegislation).
Where any issue refers to two (or three) pieces of legislation, can I store that in a single field? Or do I simply need to create a record in tblLegislation for the combined legislation?
Hey. Basically I have several tables. One table (vistiors) has a combo box in one field called Hostee. Each hostee is listed in another table with all their information. When a hostee is selected in the hostee field of the visitors table I simply need it to count how many people including the currently selected person are being hosted by the person and check if it is greater or less than the amount of people set in the host table which has a field called Limit that has a number which is the maximum amount of people one person is willing to host.
If its greater than the amount in the host table a warning message should come up informing the person (but still allow the assignment to occur.)
As a note I have the combo box set to show the first name of the individual but select both the first name and ID
the code is below for the row source:
SELECT [Hosts].[First Name], [Hosts].[id] FROM Hosts;
If someone could tell me how I could get it to show multiple things within the combo box that'd be great.
IE Right now it shows just a first name liek Alex, Rachel, Bill. I'd like it to show the first name as well as the last name and a third additional field. IE Alex Lastname T1 or Rachel Lastname F4 etc.
Can anyone show me the general code to do this? I do know some VB but I'm used to using SQL with PHP primarily. I am new to access and only know it vaguely. Thanks in advance!
I have a form that records followup activities for protocols. The form allows the user to enter up to six f/u actions from a dropdown menu in six separate fields (called fu1_action, fu2_action, etc).
I am trying to write a query that retrieves only protocols that only have one f/u action selected as "telephone correspondence" and am having trouble. It seems I could write a function in VBA that would somehow loop through the 6 f/u action fields and give a value of 1 to those that have 'telephone correspondence' as a response, and then add them up to give a total of calls for that specific protocol, and then in a separate query only retrieve those that have a total number of calls = 1, but how to get started in writing this.

I would still want to push the information to it like it does in the current new email button.

I'm working on a database which is designed to connect to an app called Canvas (www dot gocanvas dot com). It's for a client which runs a team of heating engineers. All the information regarding the engineer's job is uploaded to Canvas through their API as an XML file, and the engineers use an app on tablet to view the job details. When the engineer goes to their customer and does some work, the completed info (which parts were serviced etc) is then downloaded as an XML file via the API into the database. Also, the customer signs on the engineer's tablet to confirm that the work has been done.
Although the XML files for the job data upload and download fine, there's a different API for getting a download of the JPEG which contains the customer signature, and I'm having real problems finding out how to use this.
The API guide says this:
----
The Submissions API is restricted to authenticated users and requires a username and apassword to access. In addition, the ID field is required. If these fields aren't specified, an error is returned.
The result of this webservice invocation will be either a standard JPEG image or an error code.
Example: [URL] ....
All my code (which I've pasted at the foot of this message seems to work fine. There are no errors, and the ResponseBody object appears to contain a byte stream which would be the jpeg... if only I could get it into a jpeg file!
How I go about taking this "stuff" that's come back in the responsebody and actually create a jpeg image file from it? I feel that I'm so close that I can smell it, but can't get the last step!
Here's the existing code :
Code:
Sub DownloadImageFile()
Dim xhr As Object
Dim webServiceURL As String
Dim actionType As String
Dim PostData As String
Dim strResult As String

I am sending an email using SendObject. Sometimes it works, and sometimes it makes the computer freeze up with no error message. I have tried this with Outlook running or not running, seems to make no difference.
Code:
'The sub procedure below sends e-mail in response to a click on the Send button.
Private Sub SendMessagesButton_Click()
'For Access, define some object variables and make connections.
Dim myConnection As ADODB.Connection
Set myConnection = CurrentProject.Connection
Dim myRecordSet As New ADODB.Recordset
myRecordSet.ActiveConnection = myConnection
[Code] ....
I have added some MsgBox () to narrow down where it crashes. It is after 'Five' and Before 'Six'. On the line:
Set appOutlookRecip = .Recipients.Add(eMailAddress)
I am mystified as to why it works OK sometimes, and not others. The email address being used is valid.
