Forms :: Nested IF Statement To Check If Input Box Is Null On Form
May 9, 2014
I have a form in my Access database that has 3 input boxes by which a user can locate a record by. The problem I am running into is that I can not get a nested IF statement to work properly to first check which of the search boxes are filled in and second search by whichever is filled in. I have come up with the following code that seems to be only searching by the first input box. If the first input box is blank it does not move to the second or third numbers so I imagine there may be something wrong with the order of my IF statement or the syntax is off.
I've built a form on my Access database that invites a user to enter a start date and an end date into two textboxes. When i press a command button, a parameter query runs which uses the two textboxes as the parameter's criteria. However, to ensure that both textboxes have a data entry, i have tried entering in some VBA that prompts the user to enter in a date if its left null...then set focus to that textbox: Here it is...
If IsNull(Me.txtWeight1) Then MsgBox "You must enter a minimum weight!" Me.txtWeight1.SetFocus Else If IsNull(Me.txtWeight2) Then MsgBox "You must enter a maximum weight!" Me.txtWeight2.SetFocus Else If IsNull(Me.txtWeight1) And IsNull(Me.txtWeight2) Then MsgBox "You must enter a min and max weight!" End If
This will not compile for me! I've tried with and End If and without an End If and other stuff. Why won't it work?
I have a form called frmStartTimeEntry where a user inputs data using a barcode scanner. In this form there is a field called Part_No where after a value is inserted, I'd like the form to check if table_lines_per_part includes this part. If not found, then I'd like the form to open another form called frmLinesPerPart where the form would pull the same Part_No inserted in the previous form to fill in the Part_No field (which is hidden) and then the user would type in a qty for the LinesPerOrder. A user would then click a button btnOk to append this new record to table_lines_per_part and be returned to the frmStartTimeEntry to continue filling out the rest of the form.
This is the idea I have but I don't know how to code the part where the form checks after update if the part_no exists in the other table, nor how to capture the part_no to the other form and then append both the part_no and the lines per part to the other table.
I have a main form with many subforms. Each subform has couple of ComboBoxes or/and TextBoxes. I want to make sure that end users dont miss completing any of required values. For example, in the subform (Clients), an end user is supposed to put either "Male" or "Female" in the (Gender) ComboBox. In another subform (Job Info), the end user will put info of the job like Wage, Employer, Date of Job Start... ete.
What I want is to get VB IF statement which tests if the textboxes "Wage", "Employer", and "Date of Job Start" in the subform (Job Info) are not null, then the CobmoBox "Gender" in the subform (Clients) should not be null too, with a warning message to complete the missing value.
I have a table of dates that store all the Sundays of a year, as that is what all of our records are based on (how many items an employee sold on the week ending on such and such a date). The table is called WeekEndDates and the column is called WeekEndDate. I want to automate adding a new week, so I have a command button that has the following VB code:
DoCmd.RunSQL ("INSERT INTO WeekEndDates (WeekEndDate) VALUES (DATEADD('D',7, SELECT Max(WeekEndDate) FROM WeekEndDates)")
Any help would be appreciated, I don't know of another way to do this. I'm not sure if this is a SQL question or a VB question, so sorry if this is in the wrong spot.
I'm new to working with Access Iif statements. I'm attempting to change data values in an existing table for column named "Status." Some of the data in this column has the correct value (Active) that needed represented, while the rest is populated with either a "J" which is Active or "T" which is inactive. I needed an update query that will ignore any values that are already "Active," and convert any values that are "J" to Active and values that are "T" to "Non Active." Any help would be greatly appreciated. Below is the function I have written that's full of syntax errors:
IIf(([STATUS] T,"T") = "T", then "Non Active"), IIf([STATUS] J,"J") = "J" then "Active"), else Active = "Active"))
I am trying to calculate the time between two dates where one date field might be blank or not. Where the field is blank I want to use the current date to perform the calculation. So far I have the following but I keep receiving an error message saying that the expression has a function with too many arguments. Is there a simpler solution to this?
IIF([LastOfEnd_Date] IS NULL,(DateDiff(w,[LastOfDischarge_Date],NOW()))/4, IIF(Not isnull([LastOfEnd_Date], Abs(DateDiff("w",[LastOfDischarge_Date].[LastOfEnd_Date]))/4
I'm trying to make a nested if then statement in a query field, and I can't figure out why I can't get my formula to work:
Volume: IIf([MethodCode]="K",[total]*12.54*0.026873,IIf([MethodCode]="S",([length]*[width]*[depth])/2,IIf([MethodCode]="M" And [Location]="SH",[total]*5.08*0.026873,IIf([MethodCode]="M" And [Location]="C",[total]*18.58*0.026873," "))))
I keep getting the "data type mismatch in criteria expression" error. If I separate out all the individual if then statements individually, they work. But if I connect them all as a nested if then it doesn't work.
basically am creating a booking system, i have a add a room form. my form should check whether i already have a room number in my table, which works when the form is filled in. however when my form is null, then i press add new room button, i get this error rather than " please fill your form in"
Error: runtime error '3075' syntax error (missing operator) in query expression 'Room Number ='.
room number is a number field, integer but has primary key. i cant keep autonumber, as my requirement is to add new room number, but the roomnumber has to be unique.
here is the dlookup;
If DLookup("RoomNumber", "tblRooms", "RoomNumber = " & Forms!RoomPackages!txtRoomNumber) > 0 Then MsgBox "This number already exists." Else
I've attached screenshots of the table relationships and some nested forms that I need to discuss in my database.
If you look at the forms screenshot you'll see I have a main form "business/cmc issues" that uses a combo box to select a business name; nested into that I have a second form "policy issues log" that holds details of policy issues about that business; then inside that I have a sub form "issue updates" that records brief details about the actions carried out in trying to resolve each policy issue.
The same policy issue can affect more than one business (because of a relationship between the two companies etc) but still needs to be viewed separately. So for example in the business selector combo box I might have business "ABC". In the policy issue it might say "doesn't pay on time". The "doesn't pay on time" issue might also apply to business "123" and so if I picked that business from the combo box you'd see the same policy issue.
Because it's the same issue for two separate businesses, the actions carried out will be the same, so what I want to do is, after a new action is carried out (where relevant) to be able to click a button that would run some code that copies the actions entered in the sub form for business ABC and pastes them into the sub form for business 123 where the product area and policy issue are equal. This is to avoid having to enter the same data twice.
How (in VB) do you "check" to see if the user has selected an item from a listbox? I've searched the forums and tried everything I know and I keep getting: "Invalid Use of Null"
Hello, I am putting a check whether the inputted value in a text box(txt_id) is filled or not. If it is 'null' then it should not execute the insert statement but somehow the check for the null value is not working. Can someone tell me why??
Private Sub cmd_inserer_Click()
If txt_id.Value = Null Or txt_id.Value = "" Or txt_id.Enabled = False Then info = MsgBox("Veuillez remplir champ « Id »", vbInformation)
ElseIf txt_id.BackColor = &HFF& Or txt_libelle.BackColor = &HFF& Or txt_description.BackColor = &HFF& Then
info = MsgBox("Veuillez remplir tous les champs fausses!", vbInformation)
Else MsgBox txt_id.Value Set db = CurrentDb strSQL = "INSERT INTO objectif ( id , libelle,description) values ('" & txt_id.Value & "' , '" & txt_libelle.Value & "','" & txt_description.Value & "') ;" db.Execute strSQL db.Close
I am trying to using an iif statement to pick up null values, but I don't know what to type in the function. I tried using "is null", but got an invalid message.
What value I should type in to get null value in the function below?
After hours of playing around i finally have my IIF statement working the proplem is now is that when the Value is null it gives a blank value on my Report. How do i get it to show the value of 0 when it is Null. can i use an isNull withen my IIf statement maybe nested what is best practice?
I need to add a Yes/No field to a table. I know I can do this in design view. Next I want to loop through the table and set it to Yes if certain fields are null. What I need help with is the VBA looping part and setting the boolean field to Yes if the fields being checked are null.
I have a form that contains an unbound listbox that is populated from a table. The user selects multiple records in the listbox and then clicks on a "Commit" button. The "Commit" button then copies portions of the records to another table. (And now that I am analyzing the flow of data, I realize that not all the data needs to be copied over, but I'll fix that at a later time).
Anyway, the code looks like this:
Code: Dim lst As Access.ListBox Dim rownum As Variant Dim vHEDR, vLeague, vFname, vMI, vLname, vClass, vQual, vSex, vYouth As String Dim intResponse As Integer Dim sqlstr As String Set lst = Me![lstHistorical] DoCmd.SetWarnings False For Each rownum In lst.ItemsSelected vHEDR = CStr(lst.Column(0, rownum)) & "," vLeague = "1," vFname = Chr(34) & lst.Column(1, rownum) & Chr(34) & "," vMI = Chr(34) & lst.Column(2, rownum) & Chr(34) & "," vLname = Chr(34) & lst.Column(3, rownum) & Chr(34) & "," vClass = CStr(lst.Column(4, rownum)) & "," vQual = CStr(lst.Column(6, rownum)) & "," vSex = Chr(34) & lst.Column(8, rownum) & Chr(34) & "," vYouth = Chr(34) & lst.Column(9, rownum) & Chr(34)'<<Here>> sqlstr = "INSERT INTO tbl_RosterTest (HEDR, LeagueID, Fname, MI, Lname, ClassID, QualID, Sex, Youth) VALUES (" & vHEDR & vLeague & vFname & vMI & vLname & vClass & vQual & vSex & vYouth & ")" DoCmd.RunSQL sqlstr Next rownum DoCmd.SetWarnings True MsgBox ("Persons successfully registered")
At the <<Here>> point, I would like to proc a single dialog box the query the user for some additional information - 2 items from comboboxes and one is a yes/no. Is there a way to gather the info so I can insert the values into the INSERT string?
I have an input box and wanted user just to input 7 digital data. However, I am afraid user may enter string data. Is there any way to check and ensure user can only input 7 digital data to that input box?
I have form that user can filter the records and generate a report but I have difficult trying filter null date.
If I have check box called filter null if it has a tick in I would like it only show records that have no value (is null) in field "date start" but if unticked I would like it to only show records with a date in field "date start" ...
Im trying to concatenate a bunch of fields (50 arghh) which each are either blank or just contain one letter. This was someone elses setup for an attendance register which I think is an odd way of doing it. I would have used one field and then to get the mark for a week take a substring at the appropriate position. Anyway im trying to replace an empty string field with a letter to represent the register hasn't been marked using sql statement:
SELECT [400 Student Marks].acad_period, [400 Student Marks].student_id, [400 Student Marks].register_id, [400 Student Marks].register_group, Replace([1],"","U") AS attendance FROM [400 Student Marks];
[1] being the first register week then I would have concatenated with [2] etc...
This however causes an error each time on the attendance field so im guessing replace doesn't work on empty strings. Is there a way round this/alternative.
I have a form with two list boxes on it: listAllBANANA and listActiveBANANA
The listboxes are populated from tblBANANA. Active is defined by the tblBANANA field "ResponseDate" being Null.
Also on the form is a CloseBANANA command button. When pressed with no selection, it opens frmCloseBANANA to the first record. If a BANANA is selected in listActiveBANANA, the form opens to the selected record.
Now comes the tricky part: if a BANANA is selected in listAllBANANA, I first need to verify they have an Active BANANA selected, before opening the form. I've poked and tested and searched and cut and pasted my little fingers off with no joy. What I've deduced is that I'm either messing up the syntax of the DLookup or I'm incorrectly referencing the selected record. There's also the third option that I'm going about this in entirely the wrong way.
All other code below works. If I delete or comment out the line in red, I have no issues other than I may open up a blank form because I'm trying to close a BANANA that is already closed.
Code: 'If a BANANA is selected in Active BANANA or All BANANA, open Close BANANA to that record. If not, open form to most recent record Private Sub cmdCloseBANANA_Click() If Not IsNull(Forms!frmGUI!listActiveBANANA) Then
I have a report based on a query with 3 fields (Tested, RMA, OpenRMA). The query searches all the tables in my database and gives me a count of the equipment tested, RMA reported and open rma.
The report has two fields (Equipment, NumberTested) with a total below and also a total of the RMAs and OpenRMAs. I'm trying to hide RMAs and OpenRMAs from appearing in the body and only showing below the total. All three totals are showing correctly, but I am still seeing RMA and Open RMA with a null in the count in the body.
So in the report's Equipment.control I wanted to put
Iif([NumberTested] is null, null, [Equipment])
Meaning if the numbertested field is null the equipment field will be blank, if it is not just leave what is in the equipment field there, but it returns a #Error in the printout. It seems to handle the two null records correctly. Trying Equipment.Value also returned the same error.
