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?
I am using MS Acsess 2010 and some time I am getting ODBC Connection Error. How to increase the ODBC & Query Time Out property in MS Access?.I am using 32 bit version of Access 2010 on a 64 bit operating system.
How can I add an ID-number that always increases (by 1) each time I add a new record to a table (using a form)? I want to always use some info from the record that was added last to fill in a different form. The reason for my question is that I heard that the autonumber does not necessarily increase each time a new record is added...
Is there any way i can increase the amount of columns in a table before importing data? I am importing data from a notepad doc that needs abt 300 columns but i can only get abt 100 columns.
I have created a table in which there is one column of type memo. When I copy the content in this column it is allowing me to enter only 255 characters. How to increase the length of this column type memo?
I have a query with GroupBy. Is it causing me the damage? How to overcome this situation.
I have a table, tblEvents, which I use to store information about a meeting, training session or field trip, including the [StartDate]. I also have a table, tblEventDays, which I use to store the [DayNumber] 1, 2, 3... At the moment I have to enter the day numbers in the subform frmEventDays manually, but I would like to add button controls to increase/decrease the number of days for each event (i.e. add a new record where [DayNumber] is incremented by 1, and delete the last record if I have added too many day records).
I have added button controls to my EventDays subform and managed to use the macro builder to select and duplicate the last [DayNumber] record, but cannot figure out how to increase each successive [DayNumber] by 1.
1. Add a day...
Option Compare Database Private Sub AddDay_Click() ? End Sub
2. Remove a day...
Option Compare Database Private Sub RemoveLastDay_Click() ? End Sub
I have a form with multiple fields on it. We will call them SLO
They are text boxes and there are 6 of them named SLO1, SLO2.....SLO6
What I want to do, is use VB to update each as a string to a table individually. But Id like to only type the code once, and use a DO WHILE and increase the value by one. Example.
Current Code looks like this:
Private Sub UpdateButton_Click() Set rstNewInventoryDataRecord = CurrentDb.OpenRecordset("Select * FROM MetricData") Set CurrentForm = Screen.ActiveForm Dim Counter As Integer Counter = 1 rstNewInventoryDataRecord.AddNew rstNewInventoryDataRecord.SLO = CurrentForm.SLOT1.Caption rstNewInventoryDataRecord.Update MsgBox "Update Complete" End Sub
What I want to do is use the counter to increase by one after each loop and stop after 6. So...Do while Counter < 7
And increase the CurrentForm.SLOT1.Caption by one each time.
Is it possible to increase the number of columns in Access 10?I upgraded MS Office because I knew Excel no longer restricted you to 256 columns. I often pull data from a data base that uses as many as 800 columns.When I try to open these files I get a "too many cross tabs" error prompt.
Do you guys think the database will get small in size if i have like 200 records and each one of them have a 4 kb thumbnail as OLE object?
I know that putting big images in OLE objects gets very big but a small thumbnail is ok and doesn't increase the size of the .mdb so much? (130x98 pixels)
Can someone tell me that more remark / comment lines in VBA might be one of the reason of increasing the db size?
Because now a days I am removing the queries from my db and started to use VBA code lines behind each forms and keeping some remark / comment lines to know what a particular set of code line means and what they are doing. So I put everywhere some remarks / comments line. Now my forms are faster than before but the over all size of db become heavy.
Are comment lines one of the reason in increasing db size?
I have a main form with a few imbedded sub forms. Sometimes these is a great deal of data in one of the sub forms & non in the others. Is there a way that the sub forms can grow depending on the amount of data there is in each particular sub form. (The sub form grows for a lot of data & shrinks for little data) The way I have it now is that each sub form is always the same size and a scroll bar appears when these is extra data. This is OK but I need to see all data in sub forms at once if possible. Can anyone help with ideas please?
I have created a list that has 5 column. Data is filled in list using a query. I know how to remove 2 columns, but I do not know how to increase the width of columns.
It has been a month and I'm still 'stuck' on my Microsoft Access lessons due to a peculiar error. I have a video of the error, but it won't let me post a link until I have 10 posts. When I create an action button and then scroll at all, the button jumps in size 50% to the right and down, but this extra space can't be edited. Clicking on the 'extra space' is like clicking the background.
I have tried
1. Reinstalling Office 365 2. Reinstalling my graphics card drivers (Using a GTX 560ti SLIx2) 3. Manually entering the size for the buttons in the button properties (still increases in size)
I have a project where the schedule calls for a web-enabled database for 100+ users to merge five separate systems into one. If I can't get past this problem, I can't continue my lessons.
I just came across a problem that I didn't recognize before. I had an invoice table and corresponding form that had an autonumber for the invoice number. The problem now is that I would like the invoice number to begin at 256 and then increase incrementally, because I had some previous invoices from my books. How to go about doing this.
I'm using Dmax() to return a max number in a field which I then want to inc by 1 for a new record. Dmax is returning 999. I believe Dmax therefore thinks it's a text field. So where do I change this to a number field?
Is there a way to increase the maximum characters allowed in an expression of a macro setvalue action ?
I have an expression in a macro setvalue action that adds multiple form textbox values. I need to change the form name from "RATING ENGINE 2" to "E RATING ENGINE 2". When I do this, I exceed the maximum characters allowed in the expression. Is there a way I can rename "RATING ENGINE 2" without this problem. The expression is as follows:
I have an application with a backend db on PC 1, and the same application on PC 2 linked to the backend db on PC 1 via the network.
The link works fine but the time formats are different.
On PC 1 the time format is shortime and displays as it should i.e. in 24 hour clock format
However on PC 2, opening the same database via the network, the time format is still shorttime but when you read the time within the code it comes out in AM/PM format. Also, when the defaul tiem should be #20:00:00# but this changes to #8:00:00 PM#
Weirdly though, when you just open the table, the times are in the correct shorttime format.
Guessing, it must be a setting within the main core of Access 2003 that is different between the 2 instances?
I have a database that stores information for lab testing. Each time a tech does a "step" in the test process he logs it in the table, using an input form. There are different categories, for example preparation, testing, analysis, etc, and each of those steps take time. I have the form autopopulate the date and time with NOW() evertime the form is updated. What i want to do is calculate the time it takes to do each in days. I can easily get how many days it was from now since they logged the test, =NOW()-TestDateTime. What I want to do is get the number of days it took to do each step, ie the number of days between each event. Is there a way to do this?
I have an attendance database and I connect the time attendance machine db to my access db, what i am trying to do is to generate a report that shows the time in and time out for specific date. the type of attendance db is date/time.
Please see the attached screenshot db from attendance machine.
an also some time there is duplicate entry, I need to get the first and the last entry only for specific date.
Formatting issue regarding elapsed time calculated using DateDiff().
I understand that you can specify the output value for DateDiff(). In my case I have chosen "n" for minutes. Each result in my query shows the correct calculation in terms of minutes.
[PunchIn] = 11/23/2013 8:11:28 AM [PunchOut] = 11/23/2013 5:43:30 PM
Now when I try to format the result in terms of H:MM (be it in a form or a report) I get varied results. I'll illustrate an example below:
=Format(([ShiftLength]/60),"0") & "." & Format(([ShiftLength] Mod 60),"00") Returns 10.32 Not correct
=Format(([ShiftLength]60),"0") & "." & Format(([ShiftLength] Mod 60),"00") Returns 9.32 This is correct but I need my result to be in the form of a decimal such as my next example
=([ShiftLength]/60) Returns 9.53333333. Getting there but how do I have this result only show two decimal points 9.53?
