Modules & VBA :: Pass Combo Box To Another Form Always Null
Mar 25, 2015
I want to pass the Combobox value of one form to a textbox on another using the where condition. Using the break in VBA, the value of the combobox (in this instance "two") shows as null. the control of the combobox is [cboSubCategory] and I want it's value to pass to another form "tblCategoriesSub" (aware of the incorrect reference, as used wizard quickly - but will change if I can get it to work) to the "SubCategory" field.
I can't seem to figure out how to test a combo box null value.I try:
Code: If IsNull(Me.cboManufacturer) Then MsgBox ("Please select category") Else DoCmd.OpenReport "rptItemCategory", acViewPreview End If
This works if the combo box IS NOT NULL, but if null it gives me:
PHP Code:
Run-time error '3071': This expression is typed incorrectly, or it is too complex to be evaluated. For example, a numeric expression may contain too many complicated elements. Try simplifying the expression by assigning parts of the expression to variables.
I then tried:
Code: If IsNull(Me.cboManufacturer.Column(0)) Then MsgBox ("Please select category") Else DoCmd.OpenReport "rptItemCategory", acViewPreview End If
This works if the combo box IS NULL but if i've made a selection, it still gives me the message box as if I've selected nothing....
I have a main form with multiple combo boxes that filter a subform datasheet. In my main form combo box [PR_Filter] I added a selection titled "<Blanks>". When I select "<Blanks>", I want it to filter my subform field [PR] for NULL values. If I select anything else I want it to filter on that selection. I cannot get the NULL filter to work.
Here is the code that I have (Red is the field I need the NULL values):
Private Function PurchaseFilter() Dim strFilter As String Dim bFilter As Boolean bFilter = False strFilter = ""
I have two subforms in a tab formation sitting on a main form. They can both open up a single popup form (via a button) and that popup form is opened via openargs with the autoID field.
What I need to do is pass back a value on the popup forms [On Unload] event to the subform which opened it.
As the popup form is Modal, the subform which opened it can't be changed.
Am I right in thinking I can pass back the value to the form which had previous focus?
Previously, to pass a value from a popup form to a single form I've been using
Code:
If CurrentProject.AllForms("MyForm").IsLoaded Then do this else do this end if
But in this instance, how do I code the On Unload event in which to tell Access which form opened up the popup form, and pass a value back to it?
I'm guessing Screen.PreviousControl.SetFocus has something to do with it?
I'm working on a database that will be used when maintenance needs to be performed on our test equipment. So far, I have a form set up for the associates to track when a maintenance action has been performed. The top section of the form contains basic data about the part and there is a subform that lists the actions that need to be taken on the piece of equipment. In the subform, the associate can mark whether the action is complete or not.
If the action is marked incomplete, I wanted a separate form to appear for them to track why an action cannot be performed. If possible, I would like this separate form to automatically show the equipment ID and the action that was missed. However, I'm having difficulty getting the data to copy from the subform to the Exception form. Is this something that is possible to do?
I have a button on my main db, that opens a second db using hte following code:
---------------------- 'Dealing with external objects, use inline error trapping On Error Resume Next Dim appAccess As Object
Dim db As Database Dim strAppPathName As String Dim strAppName As String Dim strTimesheetPathName As String
[Code] ....
This code works great to open the other db, and handles wheter the other db is already open or not, but I cant seem to pass the variable to the other db using the startup switch /cmd.
I suspect if I used the shell method it would pass the cmd , but I havnt found any way to test if the db is already open with the shell method.
How can I pass a variable to the other db when opening it using VBA?
I am able to filter a data on a continuous form using drop downs and then the following code attached to a cmdbutton to create a report of the filtered data.
Code: Private Sub Command30_Click() Dim strWhere As String If Me.Dirty Then Me.Dirty = False If Me.FilterOn Then strWhere = Me.Filter DoCmd.OpenReport "rptconveyorerrors", acViewReport, , strWhere End Sub
On the same form where I filter the data i can sort it by clicking the headings aswell, however when i generate the report using the above VBA it doesn't take the sort with it and just generates it without the sort.
I am using the following VBA to sort my form
Code: Me.OrderByOn = True If Me.OrderBy = "[empname] DESC" Then Me.OrderBy = "[empname] ASC" Else Me.OrderBy = "[empname] DESC" End If Me.Refresh
I thought it may be possible to use the following sort of VBA to pass the sort however i cant get it to work:
Code: Private Sub Command30_Click() Dim strOrder As String Dim strWhere As String If Me.Dirty Then Me.Dirty = False If Me.FilterOn Then strWhere = Me.Filter If Me.OrderByOn Then strOrder=Me.OrderByOn
On a form, I want to disable the save button, 'cmdSave' whilst the form's mandatory fields have been left blank.
I've put in a smart tag, called, 'Req' against each required field and have used the following code on the forms current event.
Code: Private Sub Form_Current() Dim ctl As Control For Each ctl In Me.Controls If ctl.ControlType = acTextBox Or ctl.ControlType = acComboBox Or ctl.ControlType = acListBox Then
[Code] ....
The save button is disabled, but it won't enable again after each field has data entered against it.
I also have this code in the AfterUpdate event in each required field:
Code: Private Sub cboErrorID_AfterUpdate() Call Form_Current End Sub
There's a button(Button1) on the main form (Form1) and on the second form (Form2).On Form1, I've got a link(LinkToForm2) to Form2.When people click on LinkToForm2, I want access to open Form2 and hide/show Button1 depending on whether it is shown/hidden in Form1.
Is there a way to, maybe, set a value on Form1_Deactivate (depending on whether Button1 is shown/hidden),So that, on Form2_Activate, it can check that value and hide/show Button1 accordingly?
first form contains many textboxes second form is continuous and contains two textbox
I make a shortcut to the second form so i can open it with Shift+F1
Now when the form 2 open i want to double click on any row then the form 2 will close then the information well be copied to two specified textboxes in the form1
N.B form1 should still be opened when i open the form2
I am having problems with setting up a set of combo boxes.
What I am trying to do is if combo Productline is empty then in combo PartNumber would show all products but if combo Productline has a value selected then in the combo partnumber would only be able to select the partnumbers in that productline.
It might be an easy one but I just wasted the past hour deciphering through my code in order to solve the run-time error '94' that I'm getting when trying to execute the following code:
Code: Private Sub cmdUpdateDates_Click() '################################### 'This sub aims at combining the timesheet date and the start and end time into the fields [Start Time] and [End Time]. '################################### Dim intCounter As Integer intCounter = 0 Dim rs As ADODB.Recordset
I'm trying to add a new functionality on my search form where the user can search for records that haven't been modified(based on the field DateModified) for certain amount of time.This is what I added in my search function but it's giving me "Invalid use of Null"
If Not IsNull(Me.txtInactiveTime) Then Dim LValue As Integer LValue = DateDiff("d", Me.DateModified, Date) Select Case Me.txtInactiveTime Case "> 1 month" strWhere = strWhere & "(LValue >= " 30 ") AND " Case "> 2 months" strWhere = strWhere & "(LValue >= " 60 ") AND " End Select End If
txtInactiveTime is a combo box where the user chooses the time during which the records haven't been modified.(i.e. 1 month, 2 months etc.)
I have a form with couple of textboxes bound to a table. When the user opens the form to enter records, i want to write a function that would go through the textboxes to check whether the textboxes are left NULL. Now i can write code on button click for each form, but i was wondering if its possible to write a function that could be called for each form that i have to check for null values.
Nutshell: My user DB has one menu with 4 tabs (2 for adding records, and 2 for searching/editing records). Since the form opens up in the acFormAdd mode, Access already creates a new record (blank) before they type anything. It is resulting in blank false new records that are getting added to the table and they are getting annoying. My audit table is full of "user X created new record at this time" when it's just a blank record.
There must be a way to prevent this using VBA, but I cannot find it.
I've seen ways to disable "add new record" buttons and such, but nothing that disables Access from being smarter than me and creating a new record before I decide to.
The unbound Parent form has a listbox (SQL Server) , the selection updates the SubForm with a primary key ID. The Subform is a ReadOnly view from an Oracle Linked table. It populates with a Select * From Oracleview where ID = listboxID The code is at the link shown below update: The subform uses textboxes linked to the read-only record.
The main form can populate, no problem. However the SubForm data source is either populated OR is Null.
If it is Null, the subform stays blank. Two Objectives:
1. Set a boolean variable flag in the parent (main form) that subform record exist or that it is null. e.g. Parent obtain recordset count property from Sub form 2. Display the subform with blanks.
I am struggling trying to execute a function inside a Form_current event to display some stats.
The Function is this:
Code: Function FlightsByAircraft(Aircraft As Long) As Long Dim rst As DAO.Recordset Dim dbs As DAO.Database Dim str As String str = "SELECT * FROM tblFlights WHERE AircraftID = " & Aircraft
[Code] ....
The code for the Form_Current event is this:
Private Sub Form_Current() txtStats1 = FlightsByAircraft(Me.AircraftID)
Very simple. Well, the problem is when I move to a new record, a error message comes up: "Run-time error '94' - Invalid use of Null". It is because the AircraftID is not populated at that time. I tried to insert in the function code something like that:
Code: If IsNull(Aircraft) then exit function else .... (the DAO.Recordset code)
This is my first time writing a pass through query pinging sql tables using an input parameter from a form. I have gotten as far as executing the query but I can't seem to display the result to ensure it's pulling the right records. I also want to be able to append the records to a table. Below is the code I have written so far:
Sub GETRT()
Code: Dim db As DAO.Database Dim QDF As QueryDef Dim STRSQL As String Dim RS As Recordset STRSQL = "SELECT * FROM LAB_MESR.ODM_RT_DAYS" & _ "WHERE LOCATION_ID=" & [Forms]![PARMS]![STR_NBR] Set db = CurrentDb Set QDF = db.QueryDefs("001:GET_LT") QDF.SQL = STRSQL End Sub
I have a subform (this subform's source object can change to one of three diffrent forms) that allows the users to filter. I have a requirement to output the filtered data to excel. I am creating a query based on the subforms record source called qryExport. I now want to pass the subforms filter to qryExport. I have the string setup now I just need to know how to pass the data into the filter property of the query.
Good afternoon, I have a form with a subform and in the first txtbox of the subform in the GotFocus event I have a little procedure which checks the txtboxs on the parent to make sure that there is data in all four of the txtboxes. This works great the first time and it pops up a msgbox and it even setsfocus on the txtbox with no data in it, but if I tab into the subform a second time and there still is no data in one of the txtboxs on the parent form, nothing happens, no message and no setting focus on the txtbox with no data in it. Does anyone know of a way to get this procedure to re-set everytime a user tries to enter the subform? Thank you in advance to anyone offering and ideas and suggestions.
I have a after update event that will match the written record with any exist record in a table in the field "OrgName". If it doesn't find exact match, will call a function with a "soundex" algorithm to see if there is only a misspelling or another name altogether.
In the afterupdate event, I have a string called strOrg (wich is the name I want to compare).
I have the soundex function in a module, so I can use it for several form generally.
What I want is to pass the strOrg to the soundex function, however I don't know how to declare the variables. however I keep having this error:
"compile error: Argument not optional"
and goes to the line tagged as 1 in the private sub afterupdate
The afterupdate sub is the following:
Code:
Private Sub tOrgName_AfterUpdate() Dim strOrg As String strOrg = Me.tOrgName.value If IsNull(DLookup("orgID", "torg", "OrgName = '" & strOrg & "'")) Then resMsg = MsgBox("This organization name is not in the list. If you want to look for similar names press YES, if you want to register a new organization press NO.", vbYesNoCancel, "Organization not found")
[Code] ....
and the soundex function is declared as
Code: Public Function Soundex(strOrg As String) As String Dim Result As String, c As String * 1 Dim Location As Integer
Table: DailyExport Field: FailureGrouping (actually is offices)
I want to export all the fields from DailyExport each of our 9 offices to Excel, whetjer or not they have date in the DailyExport table. So if not, the exported workbook would only have columns headings.
I need to loop through the nine offices and export each office report to Excel.
Dim StrQry As String Dim strfullpath As String Dim SOffice as String strSQL = "SELECT * FROM DailyExport WHERE FailureGrouping = " & SOffice strfullpath = "Y:" & SOffice &" "& Format(Date,"mm-dd-yy") & "_Failures.xlsx" DoCmd.TransferSpreadsheet acExport, , FailureGrouping, strfullpath, False
I am trying to pass the results of what is selected in a list box to sql through an ado statement, when i select one result i can pass the value with no issue, when i select multiple item i get a run time error incorrect syntax near ';' i am guessing it is passing the data as a csv to sql and the where statement does not like that as criteria but i am not sure how to handle that either in vba or on the sql side.here is my vba code from access
Private Sub Command49_Click() Dim cn As ADODB.Connection Dim rs As ADODB.Recordset Dim strItems As String Dim intItem As Integer For intItem = 0 To List45.ListCount - 1 If List45.Selected(intItem) Then strItems = strItems & List45.Column(0, intItem) & ";" End If
