Modules & VBA :: ApplyFilter With Boolean And String Data?
Nov 14, 2013
I have a form used to gather data around some supplier details, and we have a review check box with Boolean data. I'm trying to establish a filter button to filter un-checked boxes by specific suppliers from a drop-down list.
Although I've been able to run filters on suppliers and the review checks separately, together I get a "Type Mismatch" error. I thought it might be because of the Boolean data type, so I tried converting that to String but get the same issue.
So far what I've created is this:
Code:
Dim Chk1 As String
Chk1 = CStr([RevChk])
DoCmd.ApplyFilter , (" Chk1 = " & Chr(34) & 0 & Chr(34) & "") And (" [Supplier Name] = " & Chr(34) & txtSupplSearch & Chr(34) & "")

I'm working on a software that was developed by someone who left the company. The problem is that the software works for all locations execpt one that is in austria, after debuging I found out that there is a statement in the code that uses boolean true or false, the only way it worked is when I put an if statement with false or true as string, ex: if doc = "true" then
buttom line has anyone faced this problem, I searched microsoft website and they said that some vb engines don't convert boolean to string. Please Please if someone has a clue try to help. Thanks.

I have an Access 2010 db which has a load of global variables of type Boolean. The values are different for each machine the database is stored on, so I have a linked table to a separate Access mdb. On startup the database opens the linked table and assigns values to each variable.
However I need to differentiate between a valuable value of False and the variable having not been set. As boolean variables default to False, this is a problem. One option is to use data type Variant, but I know this is not efficient. I am considering using data type Byte instead of Boolean, with 1 as False and 2 as True.

my teacher asked me to do Access homework to change data type from Text to Boolean. Data in "Owned car" field show as Y or N
17178
so I click on Design View and change datatype of this field from "Text" to "Yes/No" , than when I saved it show a message
17179
When I back to Datasheet view, all data in "Owned car" field change to be "No".
How can I change data type to be Boolean type without deleting my original data??? I want them to show the same as Y or N.

I have a backup subroutine which automatically triggers when the front-end is closed down (it just takes the back-end, makes a copy and compacts it).It's driven off a hidden form which I use to track who is connected to the BE at any given time. This form is opened as part of the AutoExec when the FE is opened and writes some basic user info to a table. When the form is closed, it updates the table and fires the backup process before quitting Access.
Part of that user tracking process checks to see if the same user is already connected - either elsewhere (i.e. on a different machine) or on the same machine (i.e. opening a second instance of the same FE) - which is undesirable (and, frankly, unlikely, but not impossible) A brief prompt appears to explain that they can only be connected once, at which point the application is quit (to enforce the rule) This also works fine.
I would add a public boolean variable, set it to True by default, then switch it to False if the same user is already logged on before quitting Access.Trouble is, the variable doesn't seem to be holding its value? Here is the Load event for the tracking form :
Code:
Private Sub Form_Load()
On Error GoTo ErrorHandler
Dim dbs As Database
Dim rst As Recordset
Dim strSQL As String
Call InterfaceInitialise
blnPerformBackup = True
[code]...
For some reason, blnPerformBackup is False every time, even though I set it to True at the very start of the Load event (and it is a Public variable, defined in a separate module where I store all my Public constants and variables)
why it is not retaining its value from the Load event? I've checked and it does get set to True - and when I debug, it remains True - but at runtime it reverts back to False by the time it reaches the decision whether to backup or not?

I am trying to filter a recordset with a variable q. The field in the table associated with the record set is of data type Date/time. I assigned data types String and Date to q but both cases generates the error message " Data type mismatched in expression".

:confused: I have a from with a combobox that is intended to filter a datasheet subform.
Private Sub CboFilterDate_AfterUpdate()
If [Forms]![Issues Selection and Reporting]![CboFilterDate] = "Today" Then
DoCmd.ApplyFilter , [Forms]![Issues Selection and Reporting]![Issues Selection Subform]![(Year([Opened Date]) = Year(Date) And Month([Due Date]) = Month(Date) And Day([Opened Date]) = Day(Date))]
End If
End Sub
My error reads that it can't frind the "Issues Selection Subform" mentioned in the expression.
Can anyone tell me where I messed up?

I have a form that prompts the user for a variable called PIDLookup and then applies a filter where the variable PID is equal to PIDLookup. For some reason when I run the following code I am asked to Enter Parameter Value for strWhere1. Why doesn't the program just take the user-inputted PIDLookup automatically? The code is as follows:
Dim strReport1 As String 'Name of report to open.
Dim strWhere1 As String
strReport1 = "All Visits"
strWhere1 = Me.PIDLookup
DoCmd.OpenReport strReport1, acViewPreview, ApplyFilter, "PID = strWhere1"
Thanks so much in advance.

I have to join multiple values into a string for summarizing data on reports and exports. This process in vba is taking up to 10 minutes to process and will get worse as the size of these reports grow.
My method so far is to query the individual items into a recordset, loop through the values, adding them to the string then return the string in the query.
Here is an example:
Public Function SO_Description(intSO As Integer) As String
Dim db As DAO.Database
Dim rs As DAO.Recordset
Dim strSQLSelect As String
SO_Description = "Profiles: "
Set db = CurrentDb
[Code] ....

I need to input a string into a column named "EventType". The code should first check if the column "Agent Name" contains any strings. If there is none, it will input "IBM Director" into the EventType column.
Once it has looped through the agent names, the code will then loop through the Details column and input into EventTypes based on what is displayed within the string.
These are the codes that I am using to achieve this, however nothing is being input into the EventType column.
Code:
Private Sub Command11_Click()
Dim dbs As DAO.Database
Dim rst As DAO.Recordset
Set dbs = CurrentDb
Set rst = dbs.OpenRecordset("Final")
[Code] ....
I think the problem lies with the code that checks the agent name. When I removed it, it managed to populate the EventType column based on the details. But I still need to find out how to check the agent name too.

I have a search tool, but right now it is 100% case sensitive in the sense that if i search for "test" and my entry is "Test" it will not return any results.
is there any way to setup so I could say search for "Test" and it would find "test" properly? Or even to the extreme where I searched for "Tes*" and it came back with the "test" entry.
Thanks,

I'm trying to get a value from a spreadsheet to import into my MS Access database. Currently I am trimming the spaces/carriage returns from it but need to strip some more data from the value.
Here is my code.
trimmed_department = Trim(Replace(new_department, vbCrLf, ""))
Example value being "123 Point 5 Finance and Accounting"
I want to use Mid (I think?) to remove the "123 Point 5" (it is always the same with no exceptions) but don't know how to use it as I don't know how to use multiple parameters within a string.

I need to create a user interface that will allow a boolean type search of a field. This would mean item1 AND item2 AND NOT item 3, item1 or item2, item 1 NOT item2, etc.
I've set up a combo box setup with the following script, but I can't figure out how to adjust it to allow the multiples.
Please advise if I should adjust this or try a differenmt interface format for my users.

I want to add a string as year to a date.
Somehow it doesn't work out. It should extract all records with Valid_from = 01.01.2013 and valid_to = 31.12.2013. The Year assignment works.
Code:
Public Sub BEN()
Dim strSQL As String
Dim t As Date, s As Date
DoCmd.SetWarnings False
Year = Right(pricedate, 4)
t = 1 / 1 / " & Year & "
s = 12 / 31 / " & Year & "
strSQL = "SELECT TRANSFER_PRICES.* INTO [TEMP] " & _
" FROM TRANSFER_PRICES " & _
" Where [Valid_from] = " & Format(t, "#mm/dd/yyyy#") & _
" AND [Valid_to] = " & Format(s, "#mm/dd/yyyy#")
DoCmd.RunSQL strSQL
DoCmd.SetWarnings True
End Sub

I have made a system for managing service calls and fieldworks.Part of this is checking the boards we install/service are working correctly.When the engineer calls in, we check the board - enter serial number, via ODBC talks to main server DB and pulls back what is listed below, along with ID and date/time which is all displayed in a list box.
9853911264,W-AMR,3,2:320:0:52,MAIN STORE,3.57,0,18,001.004.041,0,0*75
This works fine. In the string above are certain bits of information that need to be checked to ensure they are accurate and the board has been programmed correctly. What I want to do it, is when the user single clicks on the list box, it parses out the various sections of the above string and enters them into some text fields on the form. With some code these can then be checked to see if they are correct or not and alert the user if they are or not.
The checking part I can do, the part I am struggling with is parsing out the correct parts from the string.The parts will be the same parts required each time, and the string parts wont vary, just not sure how to go about it.

I use a form for changing data. So when the user selects a record from a listbox I fill all fields of the form with the content relating to the selected line in the box. Nearly everything runs as wished.
All updates take place immediately but the Boolean field does not update or better it updates only after I move the cursor over it. Then it is correct. To make it clear, I do not need to press a button or click, I only move the cursor over the boolean checkbox.
I access VBA after clicking the line in the listbox and use the dlookup command to get the right values. Do I need something like a requery for a boolean field ?
