Modules & VBA :: Assigning New Values To Blank Fields
Dec 19, 2013I got one months table containing a reporting_month ,timeperiod and an Index column ID with data type Autonumber.Basically I want to search through the table whenever the User types in a new reporting month or timeperiod over the dialogue.Now I want to realize the following options:
1. The user types in a new reporting month, when a record in the months table exists with a timeperiod and a blank reporting month field, it should be assigned there. For example the User types in reporting month = 032014 it should be assigned to the Time_Period Value = 042014-032015
2. Vice versa, the user types in a time period. This value shuold be assigned to the blank field beneath the existing reporting month.
Modules & VBA :: Insert Two Values From A Form In Table And Check If They Already Exist
Jan 27, 2015I'm trying to write some Code with the target to take a value from a textbox (out of a form) and a pregiven value (in this case = 2) and enter them in a new record in a table. But only if there is not already a record with the exact same combination of these to values. When done, the same button should proceed you to the next form (but this code is not already implemented in the fragment below) even if no values are added because they already exist in this combination.
Code:
Public Function GetID_PatientStudiesGroup&()
GetID_PatientStudiesGroup = [Forms]![frm_PatientStudiesGroupTZP]![ID_PatientStudiesGroup]
End Function
Private Sub BPRS_T1_Button_Click()
Call GetID_PatientStudiesGroup&
Dim strSQL As String
[Code] ....
As you can see, I tried to use a function to refer to the value out of the form, because I didn't find out how to refer to a form in an SQL Code.
Just to give you a better overview: The table where the information should be added is named "tbl_PatientStudiesGroupTZP". The form where you find the Textbox "ID_PatientStudiesGroup" (with the value I need to transport) is named "frm_PatientStudiesGroupTZP". Every part (except the WHERE NOT EXISTS part) worked perfectly for itself, but not when thrown together.
Modules & VBA :: DLookup With Multiple Values - Loop To Check Entire Table
Jul 14, 2015I have run into an issue with a basic DLookup. The database has grown in size and now we could have multiple entries, but I want it to return a certain one. So the information could be in it three times. Of course DLookup stops after the first one. How do I get it to loop to check the entire table? Someone mentioned to me to use a recordset, but how to write that as I have never used it before. Below is what I was using until this new request came up.
<code>
Private Sub txtloan1_AfterUpdate()
If IsNull(DLookup("[loan1]", _
"settlement", _
"[loan1]=""" & Me.txtloan1.Text & """ AND [status] = 'Open'")) = False Then
Cancel = True
MsgBox "Test", vbOKOnly, "Warning"
End If
End Sub
</code>
This was also executing after the user entered the information within a text field. I did not want them to enter all the data and then have it come back as a duplicate.

Queries :: Convert Boolean Fields To Integers / Blank For Null Values
May 22, 2015I have a query which returns, among other things, a number of boolean fields. In some cases, there will be a genuine True or False value in each of these fields; in others, it can and should be Null (e.g. as a result of a 'failed' LEFT JOIN of some description, where there is no associated record in the joined table which fulfills the criteria)
So something like this :
Code:
SELECT [tblTable2].[fldBooleanField]....
FROM [tblTable1]
LEFT JOIN [tblTable2]
ON [tblTable1].[SomeID] = [tblTable2].[SomeID]
However, I will be writing the result of the query to a text file and here's the problem. I want to show a numeric value for a genuine True / False (i.e. -1 and 0 respectively using the standard boolean conversions in Access) and a blank for any Null values.
So I tried this :
Code:
SELECT CInt([tblTable2].[fldBooleanField]) AS fldBooleanField....
FROM [tblTable1]
LEFT JOIN [tblTable2]
ON [tblTable1].[SomeID] = [tblTable2].[SomeID]
However, currently when I look at the exported recordset in Notepad, I am getting 0's for both False and Null values (and -1 for True)
How I can adapt my query to keep Nulls...null? And convert the genuinely present boolean values to integer form?
Only thing I can think of is to use (untested) :
Code:
IIf([tblTable2].[fldBooleanField] Is Null, Null, CInt([tblTable2].[fldBooleanField]))
But there's a number of boolean fields in there, all requiring the same treatment.
Queries :: Populate Blank Table With All Values From Another Table
Jan 23, 2015I have two tables (Table 1, Table 2). Table 1 is blank and has the fields "Field1, Field2, and Field3." Table 2 has data and 10 different fields ("Field1, Field2", etc). I want to copy all data from the matching fields in Table 2 to the corresponding Table 1. I've tried an Update Query in design view. Did not join any records, and just a simple:
Field: Field 1
Table: Table 1
Update To: [Table2]![Field5]
This returns 0 records to update. I thought about a Make Table to override the entire Table, but that isn't working either.
Modules & VBA :: Subform Date Filter That Shows All Values If Left Blank
Mar 2, 2015I am a bit of a novice when it comes to Access, but have managed to create a form with a subform embedded and various filters to show different data within the subform, including a date range filter. The code I have used for these filters is as follows:
Private Sub Command40_Click()
Dim strCriteria As String
strCriteria = createCriteria("[Introductions].Town", "List78")
strCriteria = strCriteria & " and " & createCriteria("[Introductions].Ownership", "List52")
strCriteria = strCriteria & " and " & createCriteria("[Introductions].Company", "List54")
[Code] ....
This all works fine, but I'm wondering what I need to add to this code to make it so that if the date boxes are left blank, records from all dates are displayed. At the moment I have to enter dates in order for it to work properly.

I am trying to write some code that after update of manufacturer in the form, will check to see if that serialNo and Manufacturer exist.

Modules & VBA :: How To Filter Out Blank Fields
Aug 17, 2013I am making a database which has its output in PowerPoint. I have set it up so that each field value is shown on a different slide with the code for each slide like this:
Code:
With .Slides.Add(rs.AbsolutePosition + 1, ppLayoutLargeObject)
.FollowMasterBackground = False
.Background.Fill.Solid
.Background.Fill.ForeColor.RGB = RGB(0, 0, 0)
[code]....
This works fine until a filed is blank (which they sometimes are) where it then crashes with error 94 invalid use of null. What I was thinking was putting the whole thing above in an If-then-else statement so that a blank field does not produce a slide, something like:
Code:
If IsNull(CStr(rs.Fields("Song 1 chosen_Verse 2").Value)) Then
Else
With .Slides.Add(rs.AbsolutePosition + 1, ppLayoutLargeObject)
.FollowMasterBackground = False
.Background.Fill.Solid
.Background.Fill.ForeColor.RGB = RGB(0, 0, 0)
[Code] .....
This doesn't work though - at least not like I have written it!
Modules & VBA :: Change Check Box Values Of -1 To YES And Then Fill Word Template
Jul 26, 2013I have the following VBA code that auto populates a word template:

On Error GoTo ErrorHandler:
ErrorHandler:
[Code].....
The code executes flawlessy but there are three values that are based off check boxes set as YES/NO (EMPLOYEDATREGISTRATION, EMPLOYED and FRINGEBENEFITS). These values show up as -1 for YES and 0 for NO.
Is there anyway to add code to mine that would allow me to change these values before they are sent to the Word template?
Modules & VBA :: Search Form Not Returning Records With Blank Fields
Nov 14, 2013I'm creating a search form to filter out data based on certain inputs. My VBA code looks like:

Me.FilterOn = True
Exit Sub
errorcatch:
MsgBox "Error #: " & Err.Number & vbCrLf & vbCrLf & Err.Description
End Sub
However, the output does not include records where other fields are blank. I have read that I may need to use Is Null but am not sure how to.

Check For Values In Form Field To A Table
Mar 23, 2006I'm certain this question has probably been asked before, but I can't seem to find it!
I have a form field called fldTitle, and want to ensure users write something that is meaningful by evaluating words within the title to a table of keywords (tblKeywords). I know how to write the IF/ENDIF and the other stuff required, but am struggling to find the right commands to do the comparision. Could someone help me out?
Many thanks.

Modules & VBA :: No Record In Table - Form Completely Blank
Jul 9, 2014I have a form with a drop down that links to a table where a user can select or type a record, If they type a record that isn't in the table, the form goes completely blank.

Modules & VBA :: Query A Table To See If Record Exists With Particular Field Blank
Mar 14, 2014I am trying to achieve the following - I want to query a table to see if a record exists with a particular field blank. If so, I would like to prompt the user for data.
In real world terms, when assigning an item to a user I would like to first make sure that the item is not already assigned to somebody else. I have 4 fields, UserName, Item, IssueFrom, IssueTo. So when an item is assigned to a user, the first 3 fields are populated and the IssueTo remains blank, until that item is assigned to somebody else.
At the minute I have nothing in place to prevent a user from assigning the same item to multiple users and having multiple records for the same item in the table.

If not, I want the user to continue unimpeded.
Required Entry If Check Box Is Blank
Aug 22, 2013I have a lot of fields that I want to make required entry only if one of the check boxes I have is blank. If the check box is blank then I don't want any entries to be required.
For example, I have a form that needs to be filled out only if a machine is running, if the machine is not running then only certain fields need to be filled out and the user will select the check box labeled "Machine not running".
BTW, I'm very new to Access and have no experience with implementing code, other than with excel.
