Dlookup (Too Many Tables Open)
Oct 19, 2007
I have never some across this before but my database keeps throwing a "Too many tables open error" which has taken me a day to get to the bottom of. I believe that the use of a dlookup in one of the queries not cleaning up after itself.
The issue I have now is that even importing the tables into a new database causes this problem as i guess I'm inheriting the same table id issue.
Does anyone know how to clear the table IDs that the dlookup left open ?
Secondly, could anyone suggest a more robust method of looking up one value from another table. Basically I need to look up the USD to GBP rate (one value) for every record in an other table. I cant use a join (trade ccy->fxrate ccy)as there is properties to link on. Ive tried the elookup function I found on the net but performance is still an issue.
Any help is appreciated

I'm trying to do a lookup between two tables, whereas table A includes the product ID and table B includes the price. Is it possible to create a field in table A with a DLookup function on the product ID to get the product price from table B?
Whenever I try to type in the DLookup function, it does not calculate.

In the attached Word document I have a screen shot showing the fields for the "Membership" table and "Class table." I am working exclusively with tables, no forms.
In the Membership table, I will enter a numeric value in the Class field. In the Tuition field, I want to use a DLOOKUP, which would look to the class column next to it, take that value as a lookup number, then go to the Class table (second screen shot) and locate that lookup number in the ClassID field, find the corresponding value in the Tuition column, then drop that result in the tuition field of the membership table.
Example:
In the Membership table, I enter 7 in the Class field. The tuition field should automatically return $160, because in the Class table, the classID 7 corresponds to a price of $160.
I tried setting up the Tuition field in the membership table as a calculated field, then I entered a DLOOKUP in the expression box and received an error.
Is it possible to do this type of Lookup?

This is my code.
=DLookUp("[ItemDescription]","MasterData","[BarcodeID] = " & [Forms]![frmMasterData]![Barcode])
I have a from called "TakeOn". The from is based on a table, called "tblTakeOn" with fields ID, Barcode, ItemDescription and SerialNumber.
In the form "Take On" is is a combobox named barcode, that looks up the bacode values from a table called "MasterData".
The "MasterData" table has only 3 fields, ID, Barcode and ItemDescription.
I want to in the "TakeOn" Form to, in the ItemDescription Field, display the ItemDescription from the ItemDescription value in the 'MasterData" table.
Access displays a circular reference error message.

I'm new to access and need to modify an existing database to get a report I want to create. I'm an Excel user and could accomplish what I want to do in seconds using Excel's Lookup functions, so I'm trying to do the same with Access Dlookup.
I have two tables in my database that tracks components in a hardware product. The first table is just a list of hardware units shipped. The second table is a list of various components (and versions thereof) used in each unit. The two tables are linked by a UNIT_ID field. I need to create a report showing each unit and what the various versions of the components are. My difficulty is that the component table is does not have a dedicated field for each component and each unit can be comprised of a different quantity of components. So the tables look something like this:
UNITS TABLE:
ID Customer
1 Joe
2 Bob
3 Bill
COMPONENTS TABLE:
ID Component Revision
1 Main Board A
1 Blue Board B
2 Main Board B
2 Blue Board B
3 Main Board A
3 Red Board C
I want to produce a report that looks like
ID Customer Main Board Blue Board Red Board
1 Joe A B --
2 Bob B B --
3 Bill A -- C
I setup queries to get revisions of each Board and am trying to compile into the full report, but can't figure it out. Right now I'm trying to use Dlookup to lookup data from one of the queries and insert into a larger table. I can lookup a single value fine, but can't figure out how to get Dlookup to give me the Blue Board & Red Board values for each of the system ID numbers in a master query (which would be a snap in Excel).

Hello there. Nice place you got here...
Anyhoo....I've been trying to study for MOUS Certification in Access 2000. I was going to do a bit of playing around with some practice files today, however an error occured. I could open the database with no problem, but when I went to open a table, I got an error message that simply said "Unknown" and had the OK button below that. This happens on any database that I open.
I was going to go to the Fix & Repair option that is in Access, but it was prompting me for the disks, which are at my sister's house somewhere.* I also did a search in Microsoft's website/support center and found something for the same issue in Access 2002. That was to register a DLL file by running this: regsvr32.exe C:WINDOWSsystem32msjtes40.dll. That got me another error: LoadLibrary (C:WINDOWSsystem32msjtes40.dll") failed. GetLastError returns 0x00000485. Of course, searching on that error code got me nowhere fast.
So, if there's any kind souls out there that have suggestions for me, I'd greatly appreciate it.
Thanks!
*I've borrowed this computer from my sister. It's an old winME beast that I've named Demon Spawn because I have been fighting it from the getgo. It took 4 hours to get it to recognize there's a monitor attached and a month & a half to get Internet Explorer to even run. I still think the best thing for this machine is to take it out to an abandoned field and put a bullet in the CPU.

Hello all,
Can someone please help me with this run time error I am getting:
"Cannot open any more tables".
We have 2 big forms in our application. One has 6 tabs on it with many datasheets. This form works for a while when entering data. Then about a half-hour into the application, the drop down lists are blank for new data and the "cannot open any more tables" error occurs.
I have cut down the number of tabs from 8 to 6, and decreased the datasheets by 4.
The mdb went from 14 Megs to 9 Megs with some cleanup of obsolete VBA code and redundant GUI elements. I compacted and repaired the database using the menu Tools.
It helped some, but I still get this pesky error. Then the application is useless because there is no more data you can enter.
Is there anything I can do? Any suggestions or a Microsoft web site link someone can share?
Thank you,
Sal Magnotta

Can anyone provide assistance with the above error? It comes up when I try to open a report from my form. The form has 15 tabs and approximately 5 subforms on each tab, which I suspect is causing the problem.
I have found some help on the web, but I am not sure how to use it... http://www.mvps.org/access/bugs/bugs0010.htm ...Item number one describes my situation exactly, but I don't know where to set the "record source on click" for each tab. Any help would be greatly appreciated.
Thanks!

I have a report based on a query that has data for many dates. At the moment I have put a specific date in the criteria of the query so that I could build the report format. So it now displays all the data for the date i have in the criteria section. I will need to run this report several times per week so the specified date (and corresponding data in the report) will need to be changed to a new date when I open the report i.e. when I open my report I want to show data in the report only for a specified date.
Can I create a date parameter box open up when I open the report? Can I create a form with a button that when I click will open the report displaying data for that date? What would be the best way?I also need to display the specified date on the report.

Problem:
Visual Basic run-time error 7792: You can't open a subform when it is also open in Design view.
I have a subform with properties for SourceObject, LinkMasterFields, LinkChildFields changing according to objects and events in the master form.
The subform was bound to a query before which meant that the subform load event was happening as soon as the master form is loaded. I needed to restrict the subform loading until a certain point so I removed the SourceObject property for the masterform's subform. The subform on the master form is now Unbound.
(This is because I'm now running some code on the FormLoad event for the subform which needs to be restricted until the LinkMasterFields and LinkChild Fields properties have been assigned correctly otherwise it takes ages to load.)
Now I'm getting the above error. Obviously, i do not have the subform open anywhere in design view. No Visual Basic windows are open. I've closed the db, closed access, reopened it and clicked on nothing except the masterform. The error occurs when I raise the event in the master form which assigns the sourceobject property to the subform, i.e.
Me.sfmQryAllOV.SourceObject = "sfmQryAllOV"
Can anyone help me? I've googled this but finding no answers.

I currently have a button that opens a report. the report pulls from a query that has parameters set to "fromdate" and "todate". instead of using dates and parameters that pop up as blank text boxes, I would like to click the button, have a form pop up with a combo box to select all of the options available (currently 23 options) and then click a button to make a report that only displays the record (1-23) selected. I do not need any time constraints because as the databases get updated with more records, there would be more than 23 options to choose from.

Can anyone see where I've gone wrong. The purpose should be if the value in the query is 0 or less (a minus amount) and the order number and part number matches the order number and part number on the form then a warning should appear. It's not picking up the record for flagging when it should:
If (DLookup("OutstandingQty", "qryremaininginvoiceamount", "OutstandingQty <= 0" & " And [OrdNo] = " _
& Me.[OrdNo] & " And [InvPtID] = " & Me.InvPtID)) Then

Hi,
I am pretty new to Ms Access.
I have a table which has a list of trades (Builder, Carpenter, Painter etc) going down the side and going across the top I have the number of employees (1Emp, 2Emp, 3Emp). The values in the table show the charge for that number of employees for that trade.
I have a form which has three combobox's that show the Number of Manual Employees, Number of Clerical Employees and the number of working directors and a combo box that shows the trade. What I want to happen is when the user clicks a command button on the form the charge for the total number of employees for that trade is shown in a txt box.
I have the following code attached to my button:
Private Sub GetValue_Click ()
Dim TotalEmployees As Integer
TotalEmployees = [NoManual] + [NoClerical] + [NoWorkingDir]
Value = Dlookup(TotalEmployees & "Emp", "ValueTable", "[Business] = Forms![Form1]![Business]")
End Sub.
When I type "[3Emp]" in the Dlookup it will work fine and finds the charge for that trade. But when I pass it the Result from the addition and concatenate it with "Emp" it doesn't seem to work.
I originally thought it was because I declared the TotalEmployees as an Integer by I also tried declaring it as a string - to no avail.
I just can not figure out why it will not look up the TotalEmployees.
I would much appreciate any help on this on any suggest as to how I can get the values from my table.

Please help prevent my laptop from being smashed against a wall numerous times and then being thrown out the window, after all, the wall is mostly innocent in this situation.
I have read post upon post and other dim references to DLookup in the Access Help file, etc. I am generally a bright guy (although inexperienced in DataBases, VBA and some forms of lovemaking) but I have not been able to figure out the DLookup function. Could you please give me a VERY simple explination of how to use this function and it's expressions?
If it will help, we can use the following senario...
Table_Special_Needs
Special_Need_ID
Special_Need (Data Includes: Initiatives, High Ropes, etc.)
Standard_Price
Table_Event
Event_ID
Initiatives
High_Ropes
Extra_Linens
I would like to be able to add a price field for each item in the Event table and have the table lookup the price from the Special Needs table.
Many thanks for any help you can give.
