Modules & VBA :: Using Access To Check Whether A Specific File Exists On A Website?
Aug 19, 2013
Actually what I am looking to do is have an Access application check some Web site for the presence of a number. This number could be the Serial number of the application and if this number exists to maybe show a message in the aplication or even terminate the application.
A quick and dirty way is for User Serial number 254, to put on a specific page of a Web site say arbitrary file 254.jpg (invisible on the Web site). The application would check for the existence of this file and if it is there, it could take some action. Everything would have to be done in stealth mode.
The following code can tell me if a specific URL exists, in this case [URL]
Code:
Private Sub cmdArbitray_Click()
Dim blnDum As Boolean
blnDum = blnCheckURL("http://www.VisualDentist.com")
' If blnDum = True then it exists
End Sub
Public Function blnCheckURL(ByVal strURL As String) As Boolean
Const FLAG_ICC_FORCE_CONNECTION As Long = &H1
blnCheckURL = (InternetCheckConnection(strURL, FLAG_ICC_FORCE_CONNECTION, 0&) <> 0&)
End Function
I have code working for some workers here ,who used to save excel files in a folder and my databse upload those files into database and then do the rest.I am looking for a code in vba which,on upload button matches the file in table and if the file already exists ,it should not upload again in the table and if it does not exists it should upload . I have attached my code below :
Private Sub Command0_Click() Dim strcPath As String strcPath = "O:QA FilesQC ReportingPending Review" Dim strcNewPath As String
I have a table with several thousand records. Each record as a path field that indicates a specific file that is associated with a given record (not just a directory, it identifies a specific file). I'm pretty sure that most of them are correct but I've seen and been cleaning up paths that have had typos in them or were otherwise not setup correctly. Is there a way that I can generate a report or a list of some sort that would tell me exactly which file paths exist and which ones don't? or even just the ones that don't.
i'm trying to do something that i thought would be pretty simple. what happens is i have 2 files that get used, one by access and one by excel. they are both the same, except if one gets modified then the other doesnt obviously. (theres reasons for having the 2 files).
anyway. in access i want it to pick the newer of the two files (i assume this is using a fso system object?), if the one it normally doesnt use is newer, it should copy the new one over the old one and continue using the one it normally uses.
i cant simply use the other file as another user always has that file open.
any sample code on how to check if things are modifyed at a later date? and copy/pasting using those fso objects?
I have created a form which enbles users to enter data into the fields which will add a new record to my table. What I am trying to do now is to create some kind of validation rule that will check whether the record already exists.
I need it to work this way; there are four input fields- 3 text and 1 is a date filed. When the user enters a new record they are not allowed to create a record that conatins the same combination of values. So if one record has for example filed 1 = 1 field 2 = abc field 3 = def; then no other record can have the same combination of values.
If the user enters an already existing combination there would be an error message saying which field is incorrect. If the combination doesn't exist it would add the record and display a message that the record was successfully added.
I have an application that I have automatically checking to see if tables are valid and connected, etc. If the app finds that the tables aren't connected or aren't working, it automatically tries to re-connect those tables in the background without the user's knowledge. The time I'm having trouble is if the SQL Server doesn't exists (the back-end tables are on a SQL Server). I would like to check to see if the SQL Server exists before I try to re-connect tables so that no SQL Errors pop up but I'm not sure how to figure that out with VBA.
I have a form, which has a combo box which a user can select an employee - the combo has three columns (Employee_Number, Surname, Initials) although the Employee_Number column is set at a 0 width, so not visible.
The form is bound to a query which only shows records that are 'Active'
When a user selects and employee in the combo box, I want the AfterUpdate event to check and see if there is already an active record - if there is, throw up an error message and then reveal a couple of buttons giving choices what to do next; if there isn't an active record, reveal three textboxes and then populate those textboxes with the values from the three columns from the combo.
The bit that is sticking me is the search - - I have tried DCount, but can't seem to get it to work
Here is the section of code that I am battling with:
Code: Dim EmpNo As String EmpNo = cboEmp_Check.column(0) If DCount("Employee_Number", "Incomplete_Training", "Employee_Number=" & EmpNo) > 0 Then MsgBox "Existing", vbOKOnly
I can already send emails out as PDF files when an email address exists, however, I'm trying to validate whether or not an email address does actually exist. My problem is, there are four possible locations where an email address could be: MainEmail or Contact1Email or Contact2Email or Email (the last one - Email - is in a separate table).
Four text boxes exist on the form that is being actioned (the form is based on a query to extract the relevant information) and are available to test for an email address being present. What I'm struggling with is ensuring that the 'To' box in Outlook always gets populated or Outlook chucks a hissy fit. I have been trying various IF Then Else and Do Loop plus a myriad of other ways but none are reliable, especially if no email address is present which can be the case.
I have a module that I am using to verify that file paths in my table point to valid jpg files. The table has grown quite a bit since I first created the module and it has gotten to the point where it's taking too long for the module to execute. I'm in the process of trying to change the record set for the module from the table to a stored query procedure but it's turning out to be a little tricky for me. When I execute the following module, I'm not getting any error code, it just doesn't seem to do anything at all. The bits in red are the parts I've changed. Before that the module executed as I expected it would.
Code:
Sub TestIt2() Dim strFileName As String Dim db As DAO.Database Dim rs As DAO.Recordset Set db = CurrentDb() Set rs = db.OpenRecordset("QryUpdateRevisionHistory")
I am storing values of pictures and the location of them in a table, this works fine!... using OpenRecordset. The problem is that when the function is called to store the information, it just keeps adding the same values of each file in the folder over and over again in a word "Duplicating" the information.
I have tried various methods using the OpenRecordset, but cannot seem to find the correct manor of applying the code.
Below is the function I have for storing the data...
Code: Public Sub GetFilesNamesFromFolder(strFolderPath As String) On Error GoTo ErrorHandler Dim objFSO As Scripting.FileSystemObject Dim objFolder As Scripting.folder Dim objFile As Scripting.File
I have a table in Access that I have a form saving new records to. Before this save occurs, I would like Access to check if the account number already exists and if the account does exist if it is outstanding. If both of those conditions are met I would like a message box to display and cancel the save as it is a duplicate. I can't seem to get it to work though.
I was thinking to use a filtered recordset based on one of the conditions and then perform a find on that recordset to see if it is null.
Code:
dim acct as long dim rstfiltered as DAO.Recordset Set rstfiltered = CurrentDb.OpenRecordset("SELECT * FROM tblclstrack WHERE [Request Status] <> 'Completed'") acct = Me.cd_number.Value
I'm trying to view a pdf in a form if the file exists. My search has brought me to trying the WebBrowser control. I have it loading the file but it launches Adobe instead of just showing the PDF in the window on the form.
How to search for a file using the dir function, however, i need to search for a file from a main folder which may have several sub folders.
I am having no luck so far - i understand there is a recursive search facility but im not sure how i can get this to work with what i am trying to achieve.
This is the code i have for the dir function:
If Len(Dir("as-tamworth-50midlands.qa$TamworthLaminate C of CsCircuit Foil" & CofC & ".")) = 0 Then MsgBox "This file does not exist" Else MsgBox "Yippee" End If
We have an access database which has a form that has a list box that details particular records. See attach "list box".
What I would like to do is double click on the record and this would look in a powerpoint folder (see attach "path") and open the presentation if there is a match to the value in Listbox Column 5 i.e. Tool Number.
I can get it to open the presentation if I include the tool number in the path but I cannot seem to be able to get it to compare the values and only open if there is a match.
I need some simple code that will copy an Excel file or a table in Access to a specific location on an FTP server. I would think this would be a very simple task, but I have yet to find any sample code that is *simple*. I have seen lots of code that requires downloading this dll or that mda, but the examples don't work. There must be something built into MS Access 2010 that will allow a file to be uploaded to an FTP site.
All the variables are known:
The FTP location (it never changes) The FTP Username and Password (they never change) The destination folder on the FTP site (it never changes) The File type (it never changes) The File name (available from the form in Access from which this will be executed)
I can either produce an output file, then copy it to the FTP site, or I can export the table directly to the FTP site with the file name for that day.
This seems to be a very simple task with no simple solution. Currently I am using an FTP app to get the file to the FTP site, but I would like to automate this. The process that creates the output file is already automated, so I would just like to add this to the existing code as its own module.
just made all that above up and none of it is a real function/command in VBA, but is just the kind of thing I'm looking for.
I would think that since I can download and XML file from an FTP site that it should be child's play to upload a simple file to an FTP site, but I can't figure it out.
I have been trying to come up with a solution for a problem I am having for a while to no avail. We have a backend database that stores various tables full of data. We then have a custom Excel Ribbon that connects to the database and pulls in the different tables depending on the user selection form the ribbon. Everything is working well on that end. The problem I am running into though is that in the development phase of the ribbon and database we had multiple versions and so there are still some people who are using old versions of the ribbon and therefore not connecting properly to the database. Is there some type of code I can add into the database and ribbon where it checks for a specific version to ensure the user is using the most recent version?
Basically, before any type of query is run to connect to the database the ribbon would have some sort of label on it somewhere and the database would check for that label and if it is correct, the code proceeds and if not a message box appears that tells the user they are not using the most current version of the ribbon and exits the sub?
Hi, I have the following problem which I hope someone can help me with:
I have a form which is used to enter data into a table. One of the fields is 'Code'. I want the form to check when data is enetered into this field is it already exists, ie if the code is already present in the 'code' field in the table, and if it is it should give a warning message, if not then continue as normal.
Any help would be greatly appreciated, thanks in advance!
I have a form used to enter new contacts. I would like to insert a query or macro that would automatically to see if the name (first and last) already exists in the table to which this form is attached. If the name exists, I want to open the existing record and add information to it. If not, I want to enter the information as a new record.
I have a problem where a user would enter a project code eg 113-099. I put in a list box that filters all the project codes for instance if the user enters 1 it will show all codes starting with a 1 and every additional number they enter it filters the list box to show which codes already exists! I hope this makes sense.
The problem i have is i need to check when they enter the project code that it is a unique value. The Database developer we got in didnt index this field as no duplicates allowed and as result we have large amount of duplicate project codes.
I have started to experiment with Dlookup but with no great success.
If anyone can help it would be much appreciated as i dont have much experience with access.
The field name on the form is
[forms]![projects_frm].[project_job_number] and the table which stores this information is [projects]
Is there any way to check if a particular table already exist in MS Access Database using ACCESS VBA?
Actually I'm creating temp table on the file but I want to check if temp table already exits then need to delete before creating.
e.g. I can check if query defniniton already exists using below code:
Code: If .DCount("[Name]", "MSysObjects", "Left([Name],1) <> '~' AND [Type] = 5 AND [Name] = '" & strTempQueryName & "' ") <> 0 Then .DoCmd.DeleteObject acQuery, strTempQueryName .CurrentDb.QueryDefs.Refresh End If
I am trying the get specific data out of an XML file. I managed to access a nodelist but I need more data.
This is the XML file:
Code:
<Document xmlns="urn:iso:std:iso:20022:tech:xsd:pain.008.001.02" xmlns:xsi="removed due to #posts"> <CstmrDrctDbtInitn> <GrpHdr> <MsgId>006-2012-11-09-12:21:47</MsgId> <CreDtTm>2012-10-12T12:21:47</CreDtTm>
[Code] ....
This is the code to start with:
Private Sub NameSpace_Click() Dim strFile As String Dim xDoc As DOMDocument Set xDoc = New DOMDocument Dim Nodes As IXMLDOMNodeList Dim xNode As IXMLDOMNode
[Code] ....
The extra data I need are the IBAN and Ustrd field. But they are on a different level in the XML.
Hello all, I have a form that looks at my "master table" where users put in general info about a sheet of material. There are two combo boxes on this form, Batch# and Lot#. They will use the same Batch# and Lot# for many sheets. Every time a new batch and lot are entered, this will bring up a pop-up form where the user needs to take a measurement of that batch and lot for QA. This will go into a different table, where the batch and lot #'s are unique(many of the same batch#'s with different Lot#'s). After the lot# is entered, I want to run a query in VB that looks for those unique identifiers, and if it doesn't find a record, my pop-up form will run. This is probably something very easy....... It was a very long weekend and I'm tired of thinking.
For a couple of days now I've been trying to devise a way to achieve what I want, but I just keep going in circles and hitting errors (thanks to forum members, I've been able to solve most of them.) So, here's what I want to be able to do:
Input a product using the iproduct combo box (which gets its list of values from the Products table); its brand, using the ibrand combo box; and its size using the isize textbox, all in the frmFoodSub form. I then want it to check to see if an exact record already exists (ie. the same product, same brand, same size.)
If it doesn't exist, I want to create it. If it does, I want to do nothing. Then I want the product - either the one I just created, or from a record that already exists matching the iProduct input - to be input into the product field of the PurchaseDetails table. I then want to use iQuantity and iPrice textboxs, already linked to the PurchaseDetails table, to input the newly added product's quantity and price.
I hope my explanation was clear enough. I'd appreciate any help with this you may be able to offer.
I have the following vba to check if a table exists, but I can not find on the net how to check if a form exists, I tried to modify this script but there does not seem to be a formdef
Code:
Sub table_Exists() Dim dbs As Database Dim tbl As TableDef Dim dbsExist As Object Dim tablename As String tablename = "Table2" ' Your Table Name Dim exists As String
