Refeshing Nightmare
Jul 5, 2005
Hi everyone. I was wondering if anyone could help me. I am in the process of designing a database (Access 2002, office xp), but the problem I am having is that when I am pulling in an ID number, from one form into another form, the form I want this number to land in crashes, with the warning that more than one user is trying to access the form at the same time (they are not, just me).
After having to clear this error box (a few times, it keeps reapearing) errors then appear in each of the destination forms fields. :eek:
I think it is something to do with the way the database is setup in multiuser envirionments and retry intervals etc - and I have been playing about with the values, which seems to work once, but then it goes straight back to crashing. :confused:
If anybody give me some default values that might work :o or any other remedies for this problem, this help would be very much appreciated :)
Many Many thanks.

Is there any way that I can import a text file and split the data into three columns without having to go through 65000 lines of text.
It is basically a print off of a directory structure. I have a very large text file that lists the files in folders for each of hundreds of users. I need to divide the information up into three columns so that the below data:

ends up looking like this:

BOBsongshappy 917,504 jolly.mp3

I easily imported the file into Excel, but it is still all in a column. Any advice would be appreciated.

Poor old Access. I think I've made it wave a white flag, but based on the following expression I am trying to get it to evaluate, I'm not too surprised...
The situation is that I have a large number of tick boxes on a form, which nicely filter through to a series of fields in a table whose values are either -1 or 0 (according to if the box is ticked or not). Unfortunately, I now need to generate a small piece of text for a report based on which boxes have been ticked. Deep breath...
institution:
IIf([people].[memctf]=-1,"CTF",(
IIf([people].[memwt]=-1,"Westcott",(
Iif([people].[memwy]=-1,"Wesley",(
Iif([people].[memry]=-1,"Ridley",(
Iif([people].[memwm]=-1,"Westminster",(
Iif([people].[memiocs]=-1,"IOCS",(
Iif([people].[memermc]=-1,"ERMC",(
Iif([people].[memmbi]=-1,"Margaret Beaufort Institute",(
Iif([people].[memcjcr]=-1,"CJCR",(
Iif([people].[memcym]=-1,"CYM",(
Iif([people].[memindepba]=-1,"Independent BA",(
Iif([people].[memhmc]=-1,"Henry Martyn Centre",(
Iif([people].[memregchelm]=-1,"Regional (Chelmsford)",(
Iif([people].[memregnor]=-1,"Regional (Norwich)",(
Iif([people].[memregpboro]=-1,"Regional (Chelmsford)",(
Iif([people].[memregalbans]=-1,"Regional (St Albans)",(
Iif([people].[memdiocedsips]=-1, "Diocesan (Eds and Ips)",(
Iif([people].[memdiocnorwich]=-1, "Diocesan (Norwich)",(
Iif([people].[memreg]=-1, "Regional", "Unknown"
)))))))))))))))))))))))))))))))))))))
The logic seemed to work nicely when there were just 3 options in the list, but when I try to enter the above, Access says "the expression you entered is too complex". Poor baby! :D
Does any one have any idea how I can get it to evaluate the data I need?

Many will look at this and laugh but its real.
My Access Dbs are opened in hidden state and i dont see my forms.
This must be the cause.
I tried to hide the menubars using ghudsons code,i disabled the shift key. But i dont know what has happened.
I can nolonger view them. I have tried every method out and i think the only option is to repair OS, may be it will work.
I have enabled the database which i disabled the shift key but when i hold down the shift key, it loads but the forms are totally hidden, STRANGE! ijust see the grey access background and when i click on it twice from the task bar.It pops up.
I have tried to make another database, use the autoexec macro to call a form which enables all command bars, but this works only for this database and when i press the shift key down, this database hides the toolbars and i only see the grey access background. This is happening on EVERY DB ive developed on this machine. I thought it was the access that is totally corrupted but i tried to reinstall my office and i still get the same results
This is now a NIGHTMARE to me.
When db is shifted to another machine it works fine as before.
This is REAL but can i get some suggestions from you folks before i repair my OS.

Greetings,
I'm using flash mx and MDM zinc which i assume connects using the JET rather than ADO database engine.
For the life of me cannot get a simple update to work due to the dates
involved, lost count how many hours have gone by trying!!!
Within access I can easily switch quotes and hash symbols and all SQL THREE SQL queries work without problems on my database i.e.
UPDATE UserOverallResults
SET Results = 20
WHERE UserName ='Robbie'
AND Quizdate= '19/2/2008 12:15'
UPDATE UserOverallResults
SET Results = 20
WHERE UserName ='Robbie'
AND Quizdate= "19/2/2008 12:15"
UPDATE UserOverallResults
SET Results = 20
WHERE UserName ='Robbie'
AND Quizdate= #19/2/2008 12:15#
Within the database the fields are defined as :-
Results (Integer) Username (Text) and QuizDate (Date/Time) within MS ACCESS DB schema.
in Flash MX TextDate param is a STRING and All parmaters are populated appropriately (see this later in error message).
Example of existing date data stored in database in format "19/02/2008
16:48:11" as a DATE/TIME field.
My code within in flash is :-
mdm.Database.MSAccess.runQuery("UPDATE UserOverallResults SET Results = " +
UserScore + " WHERE UserName = '"+ UserName +"' AND QuizDate = '" +textDate
+ "' ");
I've tried with and without Hashes still no joy ..
mdm.Database.MSAccess.runQuery("UPDATE UserOverallResults SET Results = " +
UserScore + " WHERE UserName = '"+ UserName +"' AND QuizDate = Format( '"+
textDate +"', "#yyyy\-mm\-dd hh:nn:ss#")");
The error message I get from the code above is ..
SQL Query has failed for the following reason: Data type mismatch in
criteria expression SQL statement: UPDATE UserResultsOverall SET Results =
30 WHERE UserName = 'd' AND QuizDate = Format('19/2/2008 19:4:35'
,"#yyyy-mm-dd hhnss#")
My text string removes the leading zeros not sure if that would cause an
issue or not (its doesnt in MS ACCESS running query) ...
Anyone have any ideas??? Losing my mind here !!
PS I had problems using '&' instead of '+' to concatenate fields.
Cheers
Rob

Hello, im having a real problem running a certain query in access. My database is used to monitor drain spillages, and the query im trying to build needed to look down a column and show descrite water spills. A descrite spill is when water spills for a bit then stops. I need to show how many times this happens in a column.
The complexity of the problem (comparing one value in a column to other values in that column) coupled with the size of the dataset (600K+ rows) just baffles everything I throw at it.
I had two stabs at it. One involved a recordset - looping through and updating a new field. Recordsets can cause database bloat - in this case it bloated the db to 2GB (Accesses maximum size causing the code to crash) - this is something I've never managed before. The other involved a function that left access frozen.
I was really stuck on this until a crazy idea came to mind, i want to know if this would work.
This might sound stupid but how about some crazy thing like adding a new column and numbering the fields, then adding some kind of query that says if the value is over 0.001 then add a 1, if not leave blank. Then have something like if the column has a 1 in it then check the next, if this one has a 1 in it then repeat this step, if not then this is 1 spill. Store the amount it starts and stops to a variable and just use that number as the Number of descrite spills.
Would this work?
Thanks,
Marley.

Hey All,
Im using MS Visual Web Developer with an Access Database, i am trying to enter a new row of data into a database via a select statment attached to a button_click event. the code i am using looks something like this.
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.AccessDataSource2.SelectCommand = "INSERT INTO [Tblissues] ([IssueDate], [IssueTime], [PlantLocation], [MachineName]) VALUES ('12/9/06', '3:00 PM', 'Gville', 'Snack2')"
End Sub
that being said. when i click the button, NOTHING happens, no error and no insert!!!
I did test the connection to the Database and its fine, i can do an update and i can read the data that exists in the database i just cant insert a new row.
This is not the first time i have delt with INSERT statments but this has me at my whits end and any help would be great.
Thanks

Hi
I have created a monster I think and I am not sure how or why.
I needed a query to tie together data from a range of tables and so it has about 20 constituent queries, each of which involves some calculation.
The query isn't so horrendous
SELECT tblApplications.lngApp, qryExpWkHomeHelp.WkHomeHelp, qryExpWkPrescrip.WkPrescrip, qryExpWkHosp.WkHosp, qryExpWkRent.WkRent, qryExpWkSup.WkSup, qryExpWkInt.WkInt, qryExpWkLife.WkLife, qryExpWkCouncil.WkCouncil, qryExpWkCar.WkCar, qryExpWkCar1.WkCar1, qryExpWkHp.WkHp, qryExpWkDep.WkDep, qryExpWkCont.WkCont, qryExpWkProp.WkProp, qryExpWkOther.WkOther, qryExpWkTel.WkTel, qryExpWkTv.WkTv, qryExpWkWater.WkWater, tblApplications.lngAppCon, tblApplications.bAppEleg, tblApplications.dtmAppGcSub
FROM qryExpWkWater RIGHT JOIN (qryExpWkTv RIGHT JOIN (qryExpWkTel RIGHT JOIN (qryExpWkOther RIGHT JOIN (qryExpWkProp RIGHT JOIN (qryExpWkInt RIGHT JOIN (qryExpWkLife RIGHT JOIN (qryExpWkCouncil RIGHT JOIN (qryExpWkHp RIGHT JOIN (qryExpWkDep RIGHT JOIN (qryExpWkCont RIGHT JOIN (qryExpWkCar1 RIGHT JOIN (qryExpWkCar RIGHT JOIN (qryExpWkSup RIGHT JOIN (qryExpWkRent RIGHT JOIN (qryExpWkPrescrip RIGHT JOIN (qryExpWkHosp RIGHT JOIN (qryExpWkHomeHelp RIGHT JOIN tblApplications ON qryExpWkHomeHelp.lngExpApp = tblApplications.lngApp) ON qryExpWkHosp.lngExpApp = tblApplications.lngApp) ON qryExpWkPrescrip.lngExpApp = tblApplications.lngApp) ON qryExpWkRent.lngExpApp = tblApplications.lngApp) ON qryExpWkSup.lngExpApp = tblApplications.lngApp) ON qryExpWkCar.lngExpApp = tblApplications.lngApp) ON qryExpWkCar1.lngExpApp = tblApplications.lngApp) ON qryExpWkCont.lngExpApp = tblApplications.lngApp) ON qryExpWkDep.lngExpApp = tblApplications.lngApp) ON qryExpWkHp.lngExpApp = tblApplications.lngApp) ON qryExpWkCouncil.lngExpApp = tblApplications.lngApp) ON qryExpWkLife.lngExpApp = tblApplications.lngApp) ON qryExpWkInt.lngExpApp = tblApplications.lngApp) ON qryExpWkProp.lngExpApp = tblApplications.lngApp) ON qryExpWkOther.lngExpApp = tblApplications.lngApp) ON qryExpWkTel.lngExpApp = tblApplications.lngApp) ON qryExpWkTv.lngExpApp = tblApplications.lngApp) ON qryExpWkWater.lngExpApp = tblApplications.lngApp
WHERE (((tblApplications.bAppEleg)=Yes) AND ((tblApplications.dtmAppGcSub) Is Null));
Well maybe it is pretty horrific!
However it is taking nearly two minutes to load on a fast PC (3.4GHz Pentium 4 with 1Gb RAM) so put it on a basic desktop and it will die.
I did wonder about fragmenting it into four queries and then putting one query at the top of the nest but reckon that's another layer and all the calculations need to be done.
Basically the sub queries are calculating a weekly value based upon input and periodicity of payments - i.e. if quarterly then it divides the payment by 13.
Any thoughts on how I could speed it up?
Thanks in anticipation
