General :: How To Define Variable In Form As String Which Can Work With Any Event
Jul 16, 2013
I have a form (Datasheet). I need to define some variable in form as string, which can work with any event. E.G in column "A"on event after update, in column "B" on event after update...
I will try to explain with a simple example : form (datasheet) columns: "A", "B"
on event after update in coulmn "A", I could have some like this:
(variable what I need to define) = 3
on event after update in coulmn "B", I could have some like this:
If (variable what I need to define) = 3 then
msgbox "ok"
end if
Now I try to work around the problem and use another column "c" to keep the value from after update A - but I know that, it's bad solution -Right?
Is it possible (and how...) to declare a module-specific form variable (or any variable for that matter) at the top of said module, so it doesn't need to be set at the start of each subsequent procedure?
I have a module of code specific to one form with a number of procedures, each one of which requires me to Dim / Set the form variable. It would be much neater if I could do it once at the start.
Code: Option Compare Database Option Explicit Public Sub Populate(lngParameter As Long)Dim frm As Form
I have a module that has a global variable defined as shown below
Module: initGlobals -----------------------
Code: Option Compare Database Option Explicit Public strGlobalUserId As String Sub initvar() strGlobalUserId = "Myuserid" End Sub
This is invoked in a login form("frmLogin") and it displays the above value before I replace it with the one that is accepted in the form.
Here is the code from the login form
Code: strGlobalUserId = Me.cboEmployee.Value
When the password is successful, I close the login form and open a form called "frmMainForm". In the form_open event of the "frmMainForm", I am trying to display the user id using strGlobalUserId but it just has spaces. What am I doing wrong?
Can anyone tell me how I use a variable I have defined within a SQL string.
e.g.
***code start ***
Dim ComputerName as string Dim Sqlstr as string
ComputerName = Environ("ComputerName") Sqlstr = "INSERT INTO ComputerName ("ComputerName") SELECT ***This is where I need help including the variable ComputerName I defined above ****
Hey all, hope this question isn't too newbiefied :D .
I have a database where I must run 10 tests depending on which product I have selected (from a drop box). Each product requires different tests (of the 10) and I am hiding the tests that I do not need after the product is selected. The way I have it set up right now is I have 10 different If statements...one for each test on the "On Change" event.
I have been trying to reduce this down to one If statement nested inside a while loop, but my visual basic isn't very good. I have named the Test buttons Test3- Test13, and want to increment just the number of the test. However, when I try to plug in my concatenated string, I have problems. My code is as follows:
Dim testcount As Integer Dim testcheck as Boolean Dim testnumber as String
testcount = 3
While (testcount < 14)
testnumber = "Test" & testcount If Me.selectedproduct.Column(testcount) = True Me.testnumber.Visible = True Else: Me.testnumber.visible = False End If
testcount = testcount + 1 WEnd
Me.testnumber is obviously not an object on the Form...so I guess my real question is, how do I get visual basic to plugin the variable testnumber so that the code reads Me.Test3.Visible.
I have a DB: This DB was sent to me via eMail (dropbox). It consist in a BE and 3 FEs. In each of the FEs I have a started form with some code activated by the Open event.
The issue: Access do nothing when I open the FEs. Note please that the DB is designed by me and it work very well on the user"s computers.
I use A2007 on Win7
The DB is in a trusted folder. Compact and Repair is not useful.
I have managed to populate a treeview with some menu items I required and it looks great but I now need to get it to do something. How do I get a tree view value (selection) to act as a variable in routine. e.g. if my tree look like this.
Menu ¦ - Compaint management I I----My compaints
When I "double click" on My Complaints I want it to a open a specific form. One I know how to do one action I should be able to figure the rest out for myself.
I am trying to set the following variable that will be used to create a PDF file in an already existing folder and name the file WorkorderIDddmmyyyy-hhnnss.pdf
The following variable setting creates the filenameddmmyyyy-hhnnssWorkorderID.pdf.
I just can't figure out how to construct it correctly.
Also, is there a way to dynamically create a folder if the folder doesn't already exist? I currently hard code the folder name but would really like to create the folder name based upon some other variable.
hello all, I am very new to access (my background is in VBA Excel, but I am not using VBA for access yet). I was wondering if some of the more advanced people can give me pointers on how to accomplish (or work my way) to make the kind of form I am trying to do. What I am trying to do is the following: I have a vending company with couple of products such as espresso, latte, black coffee, etc.. (all of the products are sold at the same price for each customer, so I might sell the products for company A for .75, but for company B for .55 etc) and I am selling these products to many clients company A, B, C, D, etc. As A start I created a table with my products, then I created a table for my clients (this one includes name, address, contact person, and machine number ). I would like to make a readout input form where it would get the customer name, machine number, each of the product's total for the readout period (this is usually every week), and the date of the readout. Now I would like the form to add a record in a table for the client machine number that was selected and maybe also in another table for the overall machine ( I am not sure how queries work, and weather I would need that or I can use queries for it). My ultimate goal is to be able to do the following with the data: - check (and perhaps graph) the overall statistics for a each of the products for all clients - do the same for a certain client - do the same for a certain machine at a client - check the overall sales of all products to all clients for each month of the year - do the same for a particular client or for an individual machine - do the same but for each year
I have done all of this in a VBA Excel based program but I was hoping to change the program to be access based instead of excel based, since this would make the data more centralized and easier to maintain, backup, check, and update.
So if anyone can post any hints or suggestion about how I should build my tables, the usability of quarries, and especially the construction of the forms I would very much thank you for that, since these are my first days getting to know access and I am absolutely confused with it, all the language you are supposed to put into text boxes, combo boxes etc....
Also if anyone knows of any good links to some online tutorials would be great, since most for the tutorials I found on a search was for constructing a for or a query using the wizard, but with no real discussion of how to bound the data to certain fields etc.
I am currently trying to create an update query (building a SQL String in VBA for a command button click event) to update a variable's value into a table.
Basically, there are 2 tables, displayed in 2 sub froms within the same main form. (OldTable and NewTable for arguments sake)
The basic method I want to implement is that a user highlights a record in the subform of "NewTable". (This value is stored as a variable "NewJPNUM" This value is then to be inserted into the highlighted row (or rows) of table OldTable on command button click.
So the basic idea is a user highlights a row in one table and this value is stored as a variable "NewJPNUM" . The user then highlights a row or rows in "OldTable" and the value from variable "NewJPNUM" is then written to field "NewJPNUM" in "NewTable" on command button click.
I am not experienced with Access but have decent experience in Excel / VBA so not really sure of best practice methods etc.
I am amending some Code I found online for an audit table, I need to store additional information in the table that is associated with some forms but not others.
I have researched about putting optional variables in, but I read this only works with the type VARIANT.
Is there a way to make a string optional as my fields contain text?
here is my code so far:
Sub AuditChanges(IDField As String, UserAction As String, Optional UserID As String, Optional DeviceID As String, Optional SimID As String) On Error GoTo AuditChanges_Err Dim cnn As ADODB.Connection Dim rst As ADODB.Recordset Dim ctl As Control Dim datTimeCheck As Date
I am trying to write vba code to enter a form. A am using an SQL statement in vba to enter the form with it.
I want to include a string variable in the WHERE clause of the SQL statement. The string variable is introduced in the DIM statement before coming up to the SQL statement.
The following is the SQL statement. numrukarta is the string variable I want to introduce. I need to know the exact punctuation to be able to insert it into this statement.
StrSq1 = " SELECT Employees.NName, Employees.SSurname, WorkItems.IDcardNo, WorkItems.DDate, WorkItems.EntryTime, WorkItems.FinishTime, WorkItems.Roster" _ & " FROM Employees INNER JOIN WorkItems ON Employees.IDcardNo = WorkItems.IDcardNo" _ & " WHERE (((WorkItems.IDcardNo)= numrukarta) AND ((WorkItems.DDate)=Date()) AND ((WorkItems.FinishTime) Is Null);" AND (Not (WorkItems.Roster) Is Null))
I have a main Part form and a Spec subform linked via Part key.
I need to add 6 Spec records automatically when a new Part is added so user can select desired Specs (default value is "n/a" for al 6 entries).
Right now I have the Spec entries added in AfterInsert for Part form, but I have to navigate out and back into record to trigger Part insert. I cannot add the Spec entries until the Part entry is added.
Is a command button my only option? Or is there another way?
AfterInsert is too late, and BeforeInsert is too early; that gets triggered as soon as the first character is typed in Part name.
I am using a public function to feed a variable string to a query. So far I have got:
Code: Public Function ClientStreetModule(firstLVar As Variant, streetVar As Variant, newFL As Variant) As String Dim cslStr1 As String, newStreet As String newStreet = Right(streetVar, Len(streetVar) - Len(newFL))
[code]....
However, I only need to use newStreet as the true part of iif, in which instance all are longer. At least I think this is the problem. I realise I might need to use NZ but am not sure how. Why it is evaluating and giving errors for all records and not just when the iif criteria is true as I want it to?
I have an access form and there is a textbox in which i enter a string and have a search button so I need the onclick event procedure to search a string from my table. so how do i do it in access 2010.
I'd like to expand me tree view automatically when a node matches a string variable from a table. In other words, when a node in a tree matches the given name (variable), the tree will expand all the way down to that name. I guess I need to use "For each node" and when the node and variable match, the tree structure will show up.
I have come up with something like this:
Code: For Each nd In Me.tree.Nodes If nd = level1 Then nd.Child.EnsureVisible Exit For End If Next nd Me.tree.SetFocus
But this only shows the first level of my tree ( btw. I have a 3 level tree). I get lost inside the FOR when I want to make use of another two variables - level2 and level 3
I have a listbox that is populated with data from a table. I would like to use one of the columns data as the where clause of a sql string that will populate another form, how do I get the selected items column data that I need into a variable? This is in Access 2010 vba.
I have a query and a form, and what I want to be able to do is have the user type in within the form the parameters for the query.
The part of the query that will hold the parameters is based on an amount (formatted as Currency), but I want the user to be able to enter >10 , =<100 or >100000 and get the correct results.
I have already set up the query and the form with unbound cells which are then referenced in the query I've tried just one cell where the user would enter >100000 or tried two cells where one cell would be for >,< etc and one cell for the value (which is formatted as currency), but that didn't work either.
The idea is that you enter the parameter and value then click on a button that runs a macro to export the query based or the user parameters, but everytime I try it I get a box appearing saying Property not Found.
I have a table of companies, with fields that contain data for 2008, 2009, 2010, etc.
I'd like to design a query that allows the user to define on a form the field, or the year, they want to query. (by text string or some other way, I am good enough with the VBA that I can figure this part out once the beginning part is figured out)
I want 2009 data, I type in 2009 and get 2009 data from a table with many years' worth of data. But I only need one query for all the years.
I notice that this is easy with reports, just use SQL in the the wherecondition, argument, but I can't find the equivalent for queries. I tried putting the text field from the form in the SQL in the query, but could not get that to work.
I am a novice to access. I am building a database in an effort to learn in the process. I wished to enquire about the possible issues that could be with defining the relationships that i have created in the project. (attached img).
I cannot seem to define a form based on these relationships to input the data.
We are creating a simple database to maintain driver license information for faculty, staff, and students who use cars from the university’s motor pool.
To do this, I have created two tables: tblDRIVER and tblLICENSE.
The fields in tblDRIVER are: pkfDriverIndex strLastName strFirstName strInitial strAddress1 strAddress2 strCity strState strZIP datBirthDate
The fields in tblLICENSE are: pkfUpdateIndex fkfDriverIndex datDateUpdated strState strLicNumber datExpirationDate ynViolations ynActive
Information about the driver is stored in tblDRIVER and the driver’s license information is stored in tblLICENSE. Periodically, we run a report that identifies drivers whose licenses are due to expire within a certain number of days. All this works fine.
My problem is that I am trying to create a lookup form that will load from a data entry form that will permit the Motor Pool Clerk to look up a driver by name and review the licensing information (which appears as a subform).
All this sort of works- I am using a combo box (based on a query) to look up a driver’s last name (which it does) and to populate all the driver’s information on the look-up form (including license information in a subform). Currently, the combo box locates the driver (including the unique index, last, and first names), and populates the form with first and last name but the rest of the information is not displayed on the look up form. Worse still, sometimes one driver’s last name matches up with the first name of the next driver listed in the table! This seems to happen only if a look up is attempted more than once. What gives.
