Modules & VBA :: Ms Access Lock Table While Inserting Data
Oct 31, 2014
In a Access 2003 database, I have an "Inscriptions" (subscription) database with a primary key on 2 fields idPersonnel (employee) and idSession. I have made a form so that user can select a session (in a listbox), then one or more employee (another listbox) and suscribe them to that session by using a button, which, on VBA side, first check that there is enough room on the session (defined by "MaxParticipants" field on "Sessions" table, linked to "Inscriptions" table on idSession), then insert data in "Inscriptions" table
This is working fine in a single-user environnement, but fails if 2 people want to join some employees on the same session at the same time, as I have a confirmation message between check and insertion. Therefore 2 users can select employees, get the confirmation message (at this point both are told there is enough room), resulting in having more people than expected joined to the session. Fortuneatly, if both users try to insert the same employee(s) to that table, one will get a duplicate error, but insertion will be made if employees are different.
On another DB engine, such as SQL server, I would use a stored procedure that would lock the table, do the check and the insertion then unlock the table.
But it does not seem to be possible in MS Access. What are the possibilities in MS Access to prevent a session from having more than maximum number of participants ?
I am trying to read from an excel file that has the same format but changes data every day due to reports that I run from a different program. I just export them to this excel file called test.xls
What I want to do is import this data from the excel file and insert it into existing data in my table. I need to this every day.
Currently I cannot get the data to append. I can only insert the data once and cannot get it to append. I tried using macros, but think it would be better to use VB.
I am building an application using MS ACCESS for a local volunteer ambulance corps and have almost complete it except for the last challenge. I have built many applications like this, with an form to add, modify and delete option for a single table. This time, the accountant asked for data to be saved before being deleted to another table so he can review it after it was deleted by a user and then delete it from that "backup" table. I am at a loss to write the code. However, being a reader of this forum taught me many things in the past and I decided to join and ask this query of the community. I know it is an insert command and I have created a mirror table for the real one with all of the twenty or so fields. The fields are the usual name, address, city state and zip with telephone numbers and some other info.
I'm new to vba programming and I've written a code which will insert a table in the current slide now i want to insert pictures in the cells of the table how can i do that?
This is my code:
Sub NativeTable() Dim pptSlide As Slide Dim pptShape As Shape ' code from google to create a table Dim pptPres As presentation Dim iRow As Integer Dim iColumn As Integer
i have a problem adding the data from the fiels on the form into a table. I know you can just click on the navigation arrows and it will save the record but i want to use a submit button as this is more user-friendly and suitable for the work i'm doing.
I have attached the database... the form that needs the code for submit button is 'frmNew_JobStatus' and the table i'm trying to insert the data into is 'tblJobStatus'
can anybody have a look at what i've done so far and suggest how i can fix this... sample code would be very usefull as i'm not an access expert.
I want to design a form , please note I have beginners information regarding Access, I have 2 tables , 1 table has Project No, Document No, DEpt NO. with all the information
There is another table-2 with Project No, Document No. and Resourcrce. There is not data in this table
What I want to do is , I want to create a form where in I select the Project No. and Dept No. When I select these items the form should list me the data in Table 1 for that Project no and DEpt No. , after this data is listed , I will add the REsource data and all this data has to be stored in table-2. I hope some one will be able to guide me on how to do this.
I am new to Access and i am designing a payroll system for my company. I have created a Table with
EMP Id, Name, Basic Pay, Total Working Days, Actual Work Days, Earned Salary, OT days, OT Hrs, OT Pay..
Now i have created a form with all the above fields.and calculated the earned salary from the control source where Earned Salary= Basic pay / Total Working Days*Actual Work Days and OT Pay =[Basic Pay/Total Work Days/8]*150%*OT Hrs.
Now my problem is i am not able to populate the fields in the table.
The command button has the code below, it works great and pops up with a window with the file name and path. I now just need the code to insert the file name and path into the table....
Code: Private Sub Toggle7_Click() Dim f As Object Dim strFile As String Dim strFolder As String Dim varItem As Variant Set f = Application.FileDialog(3)
I have a form for entry and some fields are computed or result of a query from another table. I have a function that looks up a value from another table like so
************************************************** ******** Public Function GetTargetType() As Variant GetTargetType = DLookup("type", "tblFormulations", "[tblFormulations!formulation]=Forms![frmNmsConsumptionEntry]![formulation]") End Function ************************************************** ********
Which works fine when I test in the immediate window.Then I have this form event. This however does not insert this value when I am adding records using my continuous form.
************************************************** ******** Private Sub Form_BeforeInsert(Cancel As Integer) Me!target_group = GetTargetType() 'Forms!frmNmsConsumptionEntry!target_group = GetTargetType() '[tblNmsConsumption.target_group] = GetTargetType() End Sub ************************************************** ********
making sure I can insert this value once retrieved.
I am new to access (using Access 2003) and am having trouble working with forms. Here's what I want my form to do:
-Use a combo box to select a specific system -Given the selected system, pull up ID numbers and descriptions (in separate text boxes) from two separate tables corresponding to that one system -Navigate through those ID numbers/descriptions from each table independently to find ones that match -Store the ID numbers of the ones that match into another linking table
The biggest problem right now is being able to navigate through the different table ID numbers/descriptions and add both ID numbers to a row in a different table. I've tried using a combo box with the INSERT INTO statement into the code builder, but I keep getting syntax errors.
Does anyone have any suggestions on a better way to do this?
In the above example student 1234 has a missing record in year 2004 which supposed to be Term2 in the previous year (i.e. 003) and Term2 supposed to be Term1 value in the following year (i.e. 004). Similarly for student 3311
I have a form and I want show a message on the form when the it is locked as another user is editing the data in a particular record.
I know the record selectors show the records lock status but it a very tiny symbol which will mean nothing to the users of the database and anyway I don't want record selector bar on the form. How I would do this???
I'd like a code to lock a table in my access database so that it can not be mistakingly deleted by the user. It's a very basic database program i am using for basic reporting purpose. I'd like to lock the master table from the user. How can i achieve this? Any ideas?
I am getting method of data member not found for the following code when inserting values to a table. Form has three frames. Add/Insert is on OnClick Event.
I have a DB with multiple import processes to take in information and populate various tables. This has been in place for some time and works with no issue.
The import process involves the creation of a local staging table, to which I import the received data, normalise it according to my own table structure, remove any duplication (i.e. same data imported repeatedly) and append the cleansed data to the main tables.
I've just added a validation step to check for data integrity. In other words, for duplicate data, rather than simply purge it as I was doing previously, I now check to see if the data has changed in any way and prompt the user if necessary (with the option to either ignore the change or update the existing record)
However, since I added this extra step, I am getting the following error message during my import process :
Error 3211 : The database engine could not lock table 'tblStaging' because it is already in use by another person or process
It only appears a) when a data change is detected and b) when the option to update is chosen, and seems to occur after the update has taken place (i.e. I can see the records suitably updated)
But I can't replicate the error while debugging so it seems to be a run-time issue. It's definitely not another user as the staging table is deliberately local (specific to that user's front-end)
I suspect I can probably solve the problem by adding some kind of DoEvents call or brief pause somewhere but the problem is, I don't know where the problem is occuring, so I don't know where to add the line? Or if that would even solve the problem at all?
Is there an easy function I can call to check if the staging table is locked? Which I could then use to debug and identify exactly where the lock is causing a problem? Or even apply the DoEvents to release the lock? (It must eventually get released as if I step through the code, I don't get the error?)
I have a form that allows a user to complete a stock take. I would like to stop other users from receiving or despatching stock while a stock take is in progress.
Is there a way I can lock a table, or stop users adding or altering records that match certain criteria. i.e. don't let users receive or despatch stock from with a locationID of 'A'.
I am using Excel/VBA as a frontend and Access backend. The sheet2 stores the queue name and Queue number. We have to update the sheet1 from column L to column O by looking for the values from the Access table for the date selected from the comboboxes. Now In sheet 2 , it says Queue number and in actual in access table it is the combination of Type & Type1 & Type2. So we have to look for Type & Type1 & Type2 in the table and find out total Batches ,Total Envelopes,Total documents and total pages and then store the values in the ExcelSheet1 from column L to column O.
The following formulas will be used in the select statment:
Total Batches = count(BatchNo) for date selected Total Envelopes=sum(Envelopes) for date selected Total Documents=sum(Cases) for date selected Total Pages=sum(Pages) for date selected
Function SyncSuppliers() On Error GoTo errhandle Filename = DLookup("SupplierPath", "Setup", "SetupActive = True") If Filename = "" Then Exit Function End If Set xlapp = CreateObject("Excel.Application")

The 5th row is where the problem is abbot and co will import n stop missing out the brackets (I need all the data). same for the last row A-BELCO LTD will import (HADAR LIGHTING) does not.
Code beneath worked perfectly with Access 2003.Now we switched to Access 2010 and it generates a table where data isn't put into my 77 fields like before, but seperated into 1 field, separated by some ;;;.I am not good with programming.
Dim rst_data As Recordset Dim oldname As String, newname As String DoCmd.DeleteObject acTable, "TBL_import_TPXP_Radi_Evvd" DoCmd.TransferText acImportDelim, , "TBL_import_TPXP_Radi_Evvd", "N:APPLSHAREPRDQSIGMKTDISTPWBUSPB1815RADIEV IMPACT.CSV", False, ""
I have an Excel file with a name range "DBIAS" which identifies all database data.
Then I have an Access file with a form to import that database (better, that named range) into an Access table. While importing, I have to filter some records or grouping by some field.
I cannot run correctly a VBA code to get data (filtered and/or grouped) from that name range and save those records to an existing or a brand new table.
I could get those data as DAO.recordset and printed out with "Debug.print" on immediate window, but I cannot complete the final step: writing those records to a table.
I am trying to write code in an excel worksheet to try to export excel data to a table in access.
The range in which the data is situated in excel varies. So the range address varies with the data. After a lot of searching I wrote the following code which works for a range which is fixed. The code is the following:
Dim acc As New Access.Application Range(Range("b22"), Range("b22").End(xlDown)).Select ActiveWorkbook.Names.Add Name:="ghazla", RefersTo:=Selection acc.OpenCurrentDatabase "D:PayRollFactoryJasminePayroll.accdb" acc.DoCmd.TransferSpreadsheet _
[Code] .....
As one can see from the first two lines of code I am trying to first delineate the range and then to name it. The intent is to name the range "ghazla" and so to cater for the fact that the extent of data varies.
The code works with the fixed range ="Sheet2$B140". However what I need to do is to adjust the code so that I can insert "ghazla" as the range name so that this can vary.
Now i want to write VBA code to check sheet name "Summary" in that workbook and check if any of column D value matches with Access table tblmain field "Reference" values. If yes then change the status field of tblmain to "Yes".
