Modules & VBA :: Disable Button When Text / Combo Fields Are Null
Aug 5, 2013
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
I have a form called PAF_Assignment and on this form there are many textboxes for editing. After all fields are entered, the user clicks on a button and this button populates the PAF_Issued_Date field with the actual date.
Then I want to disable (enable=False) all fields on this form once there is a date on PAF_Issued_Date as I don't want any user to make any changes after submitting it, although the user would still be able to read the information submitted.
I have tried the following...
PAF_Assignment Form AfterUpdate Event If Me.PAF_Issued_Date=Not null Then Me.FieldName1.Enabled=False Me.FieldName2.Enabled=False Me.FieldName3.Enabled=False
[Code] ......
However this is not working, there is no error message or anything but the fields remain enabled with the date...
how to add recoreds in table thru form. There are 10 fields. first two are txt boxes and rest of are combo boxes. combo box are with drop down list. But they are unbound. two txtbox are auto filled by the username and empid. Now need to write the code to update these value to table. Just i wanna do ti thru vba coding only.
how can i disable a textfield or two in a form when the textbox is unchecked also how do i add a default value for it while the textbox itself is disabled, can i get away with it by adding a default value on the textbox?
using Ms access 2010.I have two text boxes where depending on what is entered on the first the 2nd disabled.that works fine but if I make a mistake and enters a value on the 2nd while it is enabled and return back to the first and enters a value which disable the 2nd, it disable it ok but keeps the value and even save it to the table.
Private Sub q300_AfterUpdate() If Me.q300 = "1" Then Me.q300_1.Text = "" Me.q300_1.Enabled = False Me.q301.SetFocus Else Me.q300_1.Enabled = True End If End Sub
I am new to this forum, and I am facing a problem while learning MS-Access.
I am preparing a database that stores the marks obtained by students in a particular paper in addition to their particulars in tables. A query is then generated to canculate the aggregate marks and result (Pass/Fail) for the student. It is then presented in a report fomatted as a marksheet, as well as one tabulation chart.
The database is very crude in format, but I am happy with it since I do not know programming at all, and still I could make it. I have used in built menu of "ms-access" and mouse clicks only for generating query. It was a learn by doing method.
The problem is that my marksheets require absent students to be marked as "ABSENT" or something of that kind. If I convert my Null values to :
Expr2: IIf(IsNull([E_1]),"ABSENT",[E_1])
It shows ABSENT for null value, but refuses to make column total for E_1; On the other hand if I do not enter such expression, it makes column total in tabulation report, but fails to mark "ABSENT" to those who did not appear. So I have to lose one thing to gain another, while I need both.
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 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 am creating a combo box with a button. In the below vba code, I am getting the string from the combo box. Then, I am trying to use SQL to the corresponding distro lists in the table (same row). This VBA code below is getting a Run-time error '438' Object doesn't support this property or method and it points to the SQL statment in the debugging screen.
Code: Private Sub Command11_Click() Dim cnn As ADODB.Connection Dim rs As ADODB.Recordset Dim SQL As String Dim vFld As Variant
Been having trouble setting up a combo box in a form that displays data from the same line in the table into a text box.
I am trying this with a memo field without any luck. I am using a 2 column query for the combo box, the first column contains the name and the second contains the requirements (memo).
I have put in the after update code:
Private Sub CustName_AfterUpdate()
Me!CustReq = Me![CustName].Column(2)
End Sub
Can anyone please shed light on what I'm doing wrong?
I have three cascading combo boxes. How can I program a button to record the PK's from these combos into a table, but only if those values don't already exist.The 3 combos are circled in red and I want to record those values into tblJewelryInventory (circled in dark blue).
I'm fairly new to Access / VBA and have been trying relentlessly to get a text box / search button on my Access form to pull up a specific record. Although the null command produces the correct error msgBox, it does not show any record if I enter a correct primary key term.
Code: Private Sub SearchButton1_Click() If IsNull(SearchField1) = False Then Me.Recordset.FindFirst "[UniqueAEVRef]='" & SearchField1 & "'" Me!SearchField1 = Null If Me.Recordset.NoMatch Then MsgBox "No record found", vbOKOnly + vbInformation, Me!SearchField1 = Null End If End If End Sub
If (Me.cboStatus.Value = "Approved" Or Me.cboStatus.Value = "Approved as Noted" Or IsNull(Me.cboStatus) Or Me.RecordsetClone.RecordCount > Me.CurrentRecord) Then Me.cmdNew.Enabled = False Else Me.cmdNew.Enabled = True End If
End Sub
The navigation buttons work flawlessly but the cmdNew button still is enabled when it shouldn't be. THe idea is that is will be disabled if:
-current record is not the last record -cbostatus is blank(null) -cbostatus is "approved" -cbostatus is "approved as noted"
The only code that seems to work is the "me.recordsetclone.recordcount > Me.currentrecord" .
Am I going about this the wrong way? How can I check what is in the cbostatus box and have the cmdnew button enabled/disabled based on its value.
This has to be simple, but the solution eludes me.
I have a database that works really weel, but I need to do some tweaking to the toolbars to "grey out" the "sort ascending" and "sort descending" icons so that hte users do not mess with those and change how the recoerds display.
There has to be an easy way to disable those two buttons or an alternate way to ensure that the form basically ignores them.
I have a command button which will work on a specified date of every year. After the user clicks it once (which will carry out calculations), I want this button to be disabled so that it is not available for second click. Is it possible?
does anyone have any idea on how to disable a button after the event has been run? I want to give the user a few options on a form. When one is depressed i would like that option not to be available any more.
I tried forms![frmmbiinfo]![command10].enabled = false
but i guess i need to refreash the page somehow. All i keep getting is an error saying "Object doesnt support this proerty or method"
I have two questions. I have a form with 2 combo boxes. The first pulls from a simple list. Once you make a choice, the second combo box is then filtered by the first. This works correct, except that once a choice is made in the first, the filter is locked. If you change the first combo box's value a second time it does not effect the second box. The query that I am using for the second combo box has two columns that pull the first 50 characters of a pair of memo fields. Quote: SELECT MSSS.SS_ID, Left([Application_Name],50) AS Expr1, Left([Description],50) AS Expr2, MSSS.Site_Code FROM MSSS WHERE (((MSSS.Site_Code)=[Forms]![Edit or Delete Requests]![Combo6])); These fields are then used to populate 2 text fields using an event procedure. Quote: Private Sub Combo10_AfterUpdate() ' Display Partial Application Name and Description based on choice Me!txtApplication_Name = Me!Combo10.Column(1) Me!txtDescription = Me!Combo10.Column(2) End Sub This is working fine, but it starts the next problem.
I need to change the form to include the entire memo field into a text box. I was using the columns of the second combo box to fill them in. Since the combo box is limited to only 50 characters, i could only grab part of it. I am guessing there is a much better way to accomplish what I need, but I am too inexperienced with forms and vb to come up with it. Below are the fields I need from table MSSS Business_Name Application_Name Description Acronym Level_1_Support Level_2_Support Escalation_process Troubleshooting Priority Links Modified Disabled
I am looking for a way to enable a user to fill in a number of fields on a form press a button(CreateButton) and duplicate the records how ever many times is stated in a text box(TxtQty). I also need this to increase the serial number by the amount of times stated in the text box.
There will need to be another text box (TxtNextSerialNumber) stating the next first available serial number
For Example: TxtNextSerialNumber = AD-Oracle-00010 TxtQty = 5 Press CreateButton to create 5 records TxtNextSerialNumber = AD-Oracle-00014
5 new records created with the below fields duplicated and the above happening.
I will then need a message box informing the user of the serial numbers created:
'You have created serial numbers AD-Oracle-00010 to AD-Oracle-00014'
Table Name: ADOracle Form Name: ADOracleTestData
Fields Names: CustomerName: Duplicate PartNumber: Duplicate OrderNumber: Duplicate OrderDate: Duplicate HoseKit: Duplicate Returns: Duplicate Comments: Duplicate SerialNumber: + the amount shown in TxtQty starting on next serial number available.
I have two unbound text boxes and a search button adjacent each that allows me to search for a user via two methods:
1) Payroll ID 2) Surname
They have the following code:
txtPayrollIDSearch
Code: Private Sub txtPayrollIDSearch_AfterUpdate() Dim sWHERE As String sWHERE = "[PayrollID] = " & Me.txtPayrollIDSearch sWHERE = "[PayrollID] = '" & Me.txtPayrollIDSearch & "'"
[code]...
Then minor differences between the above and the Surname search.I have two questions:
1) How do I make the search more friendly by allowing it to find partial matches, i.e., a user has a surname of 'Smith' but I want to search for 'Smi'?
2) How can I display further error messages if there aren't any matches?
I'm quite new to Acces (2010) . Currently, I'm working on a form in which certain fields are set to invisible. I'd like to toggle fields to visible based on the button clicked.
Example: Field 1: O No O Yes --> When No is clicked Field 2 (containing a date) becomes visible --> When Yes is clicked Field 3 and 4 (both yes/no fields) become visible
