General :: Limit Number Of Entries Into Nested Subform?
Nov 28, 2014
I am currently trying to figure out how to limit the entries into a nested sub form to just one.
for example im making wine collection database, I have a PURCHASE table, a WINE table containing the FK of the PURCHASE PK, and an INVENTORY contain the FK of the WINE PK.
a purchase can contain many wines, but one wine can only be in one inventory location.
I am trying to add all this information with one form. I fill out the purchase details, enter the info of X bottles of wine were in the purchase, and then with one of those wines selected in their subform, i enter the inventory details for that wine. I go select the next wine in the first subform and the inventory nested subform doesnt allow another entry.
I have this code loaded into the On Current event for the main form:
Private Sub Form_Current()
With Me![INVENTORY Subform].Form
If .Recordset.RecordCount = 0 Then
.AllowAdditions = True
HeyI'm trying to create a Library database. This involves restricting the number of loans available to each member (currently 3). I need to make it so no more than 3 records exist in that table for each member. For now ive just entered a VB script that has a message box saying not to enter more than 3 loans per person but I dont think thatll be enough, I need some sort of validation for the whole table rather than a field.I know how to limit the returns of sql queries which is all I can find, but not how to limit the actual amount of entries. The loan table is part of a double query within a subform of the member form if it helps :s
My problem is the following: when I receive say 5 computers in a purchase form, I want to register the serial number of each of them in another form, bound to another table.If I receive 2 units in the purchase form, my user should only be able to input 2 records in the serial form (a continuous form), if we receive 3, then only 3 records,I cannot quite figure out how to build this second (serial number registration form), so that it refuses input after the correct number has been reached.
I am looking for a way to limit the number of rows that are added to the subform of a main form. Is there anyway that the allowable number of rows be defined using a field on the main form.
I have a form that retrieves information from a query (which of course uses data from a table).Everything is working great and I want to roll it out.will multiple users accessing the form/query/table at the same time corrupt the database or not return a result?
I have a mainform (F_main) and a subform associated (F_place).
F_place is the form of the table T_place. T_place is linked to F_main by the field "BizNumber". I also have the field "Place" and of course the "Place ID" (primary key) in T_place.
"Place" in linked to a combobox (in F_place).I want to avoid, at a given "BizNumber", the same "place" to be entered in the F_place.
I have a table 'project'. I want that the number of records in this table should not exceed 20. How can I code this is my code? And how do I set it in the 'table design'?
Hello all I was wondering if there is limitation to the number of IIf statements that can be nested in a calculated field. Basically I need to assign a particular ‘label code’ to a record that will be derived from data with in several fields within the query. The data from the table (that the query is derived from) will be completely deleted and recreated on occasions, meaning I can not write data back to the table as it would be lost when the re-creation happens. There is a possibility of many derivations for the ‘label code’ (maybe up to 100) so the nested IIf code will be substantial. If there is a better way to do what I want I am all ears however I am not a VB programmer so would rather stick to doing within the query design grid, or SQL at a stretch. Anyway the main focus to the question is there a limitation to the number of nested IIF statements.
I have a main form (frm_main) in which I have a subform as a datasheet (frm_sub1).In the first sub form I have a second (nested) subform (frm_sub_sub2) as a datasheet as well.
On the main form I have an unbound text box which gives me the value of the ID field in the nested subform (frm_sub_sub2).In the main this works well, however, I hit a problem at a particular point.
If I expand an entry in the first subform (frm_sub1), then, in the main form (frm_main) I get the first ID value from the corresponding records in the nested subform (frm_sub_sub2) as expected, which then changes as I scroll through the expended records.
However, if I then expand another entry in the first subform (frm_sub1) without collapsing the previous entry, the ID value shown on the main form (frm_main) from the nested subform (frm_sub_sub2) remains the same and doesn't change to the currently selected record. Even if I then collapse the first selected entry on frm_sub_sub2 - the original ID value still remains on the main form (frm_main).
I didn't know that Access is supposed to only have 2 subform deep. On my form, I have three subform deep. However, the master form is unbound, not linked to subforms, and nothing more than a container for tab pages which contains their own subforms and has no code directly associated with data. There is a code to move subform to new record when tabs changes, but that's all.
Does that mean there is really only two subforms deep from the topmost form on the tab page or the subform depth has been exceeded whether the master form has no role in data transaction?
I have searched for an answer to this question a lot, but I could not find it. I hope anyone can help me with the following:
I need to do a database in MS Access; however, there is so much information and some of it is not related. After normalising it, it looks like I need a number of tables. Is there a limit to how many tables you can have on Access? And how many tables is the recommended size?
Is there a limit on the number of records you can have in an access database? I've got one with 8500 records and it's been a PITA! I have a webpage on our intranet so users can go and enter their information to it, and they get a nasty error whenever they try to enter information. I'm trying to figure out why and i was just wondering... i know it's not the webpage because when i connect it to my test database it works fine? so i dunno :confused:
Hi All. Is it possible to limit the number of records in a form, to a number given in a linked form.
For Example.
tblA StreetName No_Of_Houses
tblB Name Number
I would only want the number of records in tblB to be the same as No_Of_Houses in tblA. I have seen previous threads where you can limit it to a number, but do not know where to go from there.
I am designing a database for a marketing company. One of my tables has all of the company's contacts. On the contacts form, I have a button that opens up a query that shows the information for the company that contact works for. I have a problem where if I have more than one contact per company, it will return that many results (which is just a repeated list of the same company information). It is an eyesore to look at the same information in two or more rows, so I was wondering, can I make the query return only one result? I've been looking online, and I haven't found this at all. Thanks a lot.
I have searched to find the correct syntax to refer to a combo box control on a nested subform. All the examples I've found Access 2013 will not recognize or find the appropriate control.
I have a parent form called IncidentDetails. On that form I have a control called ctrlLogDetail. Within that control is a form called sfrm_LogDetail. On sfrm_LogDetail, I have a control called ctrlType which houses a form called sfrmType. On sfrmType, I have a combo box called cboType. I need to be able to place the cboType choice into a query to filter records for another combo box on that same form. the query works appropriately when I have sfrmType open, however as soon as I try to call the query from the IncidentDetails form, Access cannot find the cboType control.
I've tried multiple variations of the syntax to call to cboType that I've found online. I found a very useful reference from BTA Development: however the syntax there will NOT work in Access 2013.
What is the appropriate syntax would be to get to my control within my 3 deep nested subform? I'm working Access 2013 and won't have a choice regarding Access versions.
My boss has a table with tons of fields on it, he designed it this way because it was easier to add data to one place, but now the table keeps crashing, does ms 2k have a limit to the number of fields in a table?? Thanks in advance.
I only seem to be able to add some 30 calculated fields to a form or report. Anything over this returns a #Name? error. I've seen this before but have searched this and other forums but cannot find an answer. I suspect a memory issue but I have 2 gb on Pc. Any Ideas?
I have a text box, which requires a 8-digit number entry. I have wrote the code to check that the length is 8 and if it isn't a label will turn visible next to the field telling the user entry must be 8 digits.
This works for when i enter a number less than 8-digits but when i input a number with more digits as it does not fit into the text box it turns it to a scientific format value and when the code runs it shows the length is actually 8! And therefore the entry is valid!
I.e. when i input 123456789 the text box shows 1.23E+08 which is 8 charecters!
I dont want any error messages to pop up as i handle them by code and use labels to show the error message next to the problem field and i would like to keep this consistent. Is there any way i can do this by a function or a property in the table or form?
I have a small database which lists delegates for courses. I have a venue which will hold only a small amount of people is there a way of stopping data entry when it gets to a certain point. ie putting a limit on how many columns can be entered on a single table
I am new to Access and I am developing a form. I have already read and found useful resources on internet but there is something I am not able to sort out.I have seen that the limit of fields I can enter in Access is 255 and my survey is far below that number.So no issue at all when I created the fields in Data view.However, the issues started when I created a form.
I created a form by Create>Form.The last few fields, at the very bottom of the form, are squeezed onto each other as if there was not any space available. Is there a limit to the number of fields I can have in a form? There should not be if I am allowed to enter up to 255 fields. How can I go about it? Should I alternatively create 2 forms? I would rather not to though.
I have a ODBC (Firebird) table linked using a DSN connection which has >300 fields. In Access, the linked table only show 256 fields (max for Access). Otherwise the link works fine. I have no control over the source Firebird table.
What I'd like to do is limit which fields from the Firebird table are shown in Access. I don't need all the fields, but I need some that are at the end and are not linked in the current setup.
I'm very much a novice at using ODBC, but can I somehow use SQL or some other method to specify which fields to show in the linked table?
Ok, not sure if this is even possible or where to even start..
I've got a form that has all the info for a client, eg.. Client First Name Client Last Name Client Hours Client WE/CS/EE Client Day And Times Client Phone Client Comments
Begin Date & End Date (2 boxs) on there for date input..
and what i'm trying to do is limit that any date entered between begin date and end date, it'll check and make sure there is only ever 20 clients on any 1 day..
i thought Datediff would be the way to go, but then again how do you get it to search each day and make sure theres only 20 clients on there..
