Modules & VBA :: Check If File Exist On HTTP Server
Sep 13, 2013
I found and modified this code to allow me to check (fast) if a file exist on a http server or not (without downloading it).
Code:
Public Function CheckNetFile(WebFile As String)
Dim XmlHttpReq As Object
Set XmlHttpReq = CreateObject("Microsoft.XMLHTTP")
XmlHttpReq.Open "HEAD", WebFile, False
[Code] ....
In the above code I managed to declare Webfile as a string so I can call on it later but one thing I still need to tweak is to also get a result out of the test code in a better way than having to publically declare the "CheckNet" variable somewhere else in my app.
First prize would something like this:
If CheckNetFile ("http://www.mysite.co.za/test/test.txt") = 1 then "Yes" else "No"
How do I build the 'booleon check' into the original function?
I'm working on a database which is designed to connect to an app called Canvas (www dot gocanvas dot com). It's for a client which runs a team of heating engineers. All the information regarding the engineer's job is uploaded to Canvas through their API as an XML file, and the engineers use an app on tablet to view the job details. When the engineer goes to their customer and does some work, the completed info (which parts were serviced etc) is then downloaded as an XML file via the API into the database. Also, the customer signs on the engineer's tablet to confirm that the work has been done.
Although the XML files for the job data upload and download fine, there's a different API for getting a download of the JPEG which contains the customer signature, and I'm having real problems finding out how to use this.
The API guide says this: ---- The Submissions API is restricted to authenticated users and requires a username and apassword to access. In addition, the ID field is required. If these fields aren't specified, an error is returned.
The result of this webservice invocation will be either a standard JPEG image or an error code.
Example: [URL] ....
All my code (which I've pasted at the foot of this message seems to work fine. There are no errors, and the ResponseBody object appears to contain a byte stream which would be the jpeg... if only I could get it into a jpeg file!
How I go about taking this "stuff" that's come back in the responsebody and actually create a jpeg image file from it? I feel that I'm so close that I can smell it, but can't get the last step!
Here's the existing code :
Code: Sub DownloadImageFile() Dim xhr As Object Dim webServiceURL As String Dim actionType As String Dim PostData As String Dim strResult As String
I'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.
In the code below I want to wait for ten seconds if there is connection to the server, if not to exit the sub with message "No connection to server". How to check it
Dim req As New XMLHTTP60 Dim resp As New DOMDocument60 Dim xmlNodeList As IXMLDOMNodeList Dim myNode As IXMLDOMNode Dim xmlNode As IXMLDOMNode Dim presription As IXMLDOMNode
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.
How I can check if connection to SQL server is established with VBA before the SQL is executed. btw I use VPN connection to connect to sql server, and some times VPN connection is going down in middle of work and it is quite unconvinced.
I would like help with a macro that looks to see if a record in my database table exists, then if it doesn't it adds a record with my data, but if the records does exist, it stops the routine and sends a message box to prompt if you want to continue with adding a new record.
The problem that I'm having is that my macro errors out when it doesn't find a record. I just want my macro to just see if a record exists or not. Then I can write my Iff statements based on whether it finds our or not. How do I just have my macro check for an record, then if it doesn't exist tell that it doesn't exist and not stop my macro. Is there some kind of IfExist() function or something?
I put a Dlookup function to compare the new entry in a form and the code is like this:
If (Not IsNull(DLookup("[empno]", "Attnd_tbl" , "[empno]=[empnotxt]")))then MsgBox "This Employee Already Exists" cancel = true Me!empnotxt.undo end if end sub
this works for comparing one field only, since I want to check if the employee is already entered on a certain date, how do I put two fields in this function to be looked up if for example "[empno]and[date]","Attnd_tbl","[empno]and[date]=[empnotxt]and[datetxt]"
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 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
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 a parent form which has a yes/no checkbox in the form's record source. Then in that parent form I have a sub-form. If NO records exist in the sub-form I want the checkbox to be UN checked. If records DO exist in the sub-form, I want the checkbox to be CHECKED.
But I want this to happen as records are added or deleted from the sub-form. In other words, if the parent form is opened and no records exist in the subform then the checkbox should be unchecked. But as soon as the first record has been entered in the subform, the checkbox on the parent form should be checked. Likewise, as soon as the last record has been revoved from the sub-form, the checkbox on the parent form should be unchecked.
I have a form with more records lines. For each record I have a button what will open a specific file if exist.
Dim strFoldername As String strFoldername = Me.Scan If Dir("M:Applications AccessCredit autorisationsDocuments" & strFoldername, vbDirectory) = "" Then MsgBox "Missing document" Else FollowHyperlink "M:Applications AccessCredit autorisationsDocuments" & strFoldername End If
To verify if the file exist, instate to press the button, I like to indicate on a new field [Ctrl_Doc], the presence of respective file. (Ex: True or False). I tried this, but doesnt work:
Private Sub Form_Load() If Len(Dir("M:Applications AccessCredit autorisationsDocuments" & strFoldername, vbDirectory) >0) Then [Ctrl_Doc]= True Else [Ctrl_Doc]= False End If
I'm experimenting with MS Access, and I've successfully split an MDB someone created into two files. I can access the database from 2 computers at once using the front end file connecting to a file server which hosts the _be.mdb file.
Could the _be.mdb file theoretically be on a NAS without any computer attached, or is there some runtime or full version of Access that needs to run on the machine with the back end file?
I use a batch file to distribute the front end of a database application. Currently, everytime the user clicks the shortcut on her desktop, the batch file executes and copies the front end from a network location to user's local machine. The FE is updated like every couple of days. The users run the database more frequently.
I would like to modify the batch file so that it checks some attribute of the FE file to decide whether it needs to be updated. I can't rely on file size, since the FE includes temporary tables. I essentially need something like the "tag" property of form controls, only for files. It would be ideal if it was me who sets this property, like "version number". Except it has read without opening the file itself.
I need deleting a file from a ftp server. I have the code for uploading but I can't seem to figure out how to delete a file. This is the FTP module I'm using
Code:
Public Sub UploadFileToFTPServer() On Error GoTo ErrHandler Dim lngRet As Long Dim abytData() As Long Dim lngBytesWritten As Long
[Code] ....
And this is the code for uploading i use in the form when i click a button
Code: Dim objFTP As FTP Const conTARGET = "ftpserver" Set objFTP = New FTP With objFTP
[Code] ....
All that works like a charm.
Code to delete a file from the ftp server, i'm kind of stuck.
I'm having problems creating a second subfolder in the main folder.
The main folder is used to keep inside the reviews of clients inside.
The code I have now, will only create a main folder if it does not exist and then a subfolder with the BIN nr, type review and date. If the client would have a diferent ones and in diferent years. So if it has first "Prototype Model", the next one could be "Prototype Review". The part of the code that checks if the main folder exist works, but how to let the code create in the main folder the second review subfolder? Please see below code I managed so far:
Code: Private Sub btn_Create_Folder_Click() 'XXXXXXXXXX working onXXXXXXXXXXXXXX Dim path1 As String Dim path2 As String path1 = "C:Test_FolderMedium" & Me.BIN & "_" & RTrim(Me.LE_Name) & "" path2 = "C:Test_FolderHigh" & Me.BIN & "_" & RTrim(Me.LE_Name) & ""
I want to do it bring up a form from which the user can send an email, and on the form is an unbound text box [Text1] in which the user can paste the attachment path.
Code: Dim olApp As New Outlook.Application Dim mItem As Outlook.MailItem ' An Outlook Mail item Set olApp = CreateObject("Outlook.Application") Set mItem = olApp.CreateItem(olMailItem) ' Add the To/Subject/Body to the message and display the message
[Code] ....
So, when I paste the file location into Text box [Text1] I get the Run Time error that the path does not exist or is not valid. Yet when I use the next line which is the same path, all is OK.
I have just started working with a team on a database that is available to everyone in this office. We have tried to lock it out and assign permissions by using workgroups, running security wizard, giving users no permissions, and deleting the Admin user, however none of this has sealed the database. The workgroup file is seperate folder on the server and the shortcut we make people use links to that workgroup. However Access is still defaulting to seperate workgroups on users personal computers. Is there anyway we can prevent this? Thanks.
I'm having trouble viewing values that exist in table 'tblTest2' to the user. The first set of code (below) doesn NOT work. Yet the second set of code (all the way at the bottom) DOES work. And by work I mean that it erases the old values and only puts the tblTest2's new values. The first set of code has values but they are not the right ones. The second set of code has the correct values for its statement...
Code:
strTable = "tblTest2" 'Table for storing values for viewing purposes DoCmd.DeleteObject acTable, strTable 'Delete tblTest2 old values CurrentDb.Execute "CREATE TABLE tblTest2 " _
I currently have this set as the forms default recordsource (which works just fine):
Code: SELECT TOP 5 tblUsers_Phone_Book.EMAIL_ADDRESS, weightedDL('me@mine.com',[EMAIL_ADDRESS]) AS Expr1
And I have this vba to dynamically switch around that email address.
Code: Private Sub Form_Load() Dim intPos As Integer Dim strControlName As String Dim strValue As String Dim sSQL As String If Len(Me.OpenArgs) > 0 Then ' Position of the pipe
[Code] ....
If I msgbox the sSQL - it shows identical to the default recordsource but I get the error:
The error message I get is:
Run-Time error '2580' The record source 'SELECT TOP 5 tblUsers_Phone_Book.EMAIL_ADDRESS, weightedDL('me@mine.com',[EMAIL_ADDRESS]) AS Expr1' specified on this form or report does not exist.
I tried copying the exact working default sql into the vba and get the same result.
I want to check if data entered in a form field is existed
The form is bounded to a table
I used this code
If DLookup("Telegram_Number", "tbl_Violation_Of_Building", "Telegram_Number Like " & Forms!frm_Add_Violation_Building!Telegram_Number) Then MsgBox ("number existed") Me.Telegram_Number = "" Else End If
everything is ok but if the data is existed the database show the message and clear the field but i'm getting a Run-time error
'-2147352567(80020009)': the macro or function set to the beforeupdate or validationRule property for this field is preventing [ISF] from saving the data in the field
I guess the problem because the form is bounded to a table so he will save automatically
My solution is to unbound the fields and save the data via vba but is there any solution with a bounded form???
We have a server that we use to run a Microsoft Access application. This application creates folders, subfolders and files on the server.Users are in 4 different offices. Each office has at least 3 computers. Some users also work from home.
Users creates file through word, or scanning a document or by saving an email on their local pc.My problem is that users need to be able to save a file to a specific folder on server.
We are on Win7 with Office 2013 (32-bit). I have had to migrate my application away from a network that is open to the web. I am now on a more isolated network. My problem is that I can no longer use Outlook for e-mail.
I knew that you can use CDO to send SMTP via a Mail Relay server. We've got one of those on this isolated network... but there is a show-stopper here. When setting up the configuration portion of the CDO message, there are these references using
CDO.Configuration.Fields.Item("HTTP:schema.micro soft.com.... etc.) = value
These references are how you define the SMTP server, server port, authentication method, etc. My problem with this is I can't get to that Microsoft site from the isolated network. The SMTP Relay won't do this lookup for me and I have no general internet access.
When I looked into the CDO library, I found that there were definitions for the fields like cdoSMTPAuthenticate and cdoSMTPServer and cdoSMTPServerPort - but when I attempt to use them, Access doesn't seem to like them even though the CDO library is checked in my references list and those values are defined. For what it is worth, the library file says it is version 6.6.7501 (or something close to that), so it is not the older version. The revision date is 6/6/2012, just about right for a file that would have been included in Office 2013's library set.
How to use CDO when you can't do the HTTP lookups? (I know how to use it when the lookups work...)
