How To Check A Computer Client Allready Off ?
Jan 18, 2007
Right now i using client server application using
- Frond End : Ms.Access + Winsock with UDP protocol. ( This program like Yahoo Messenger )
- Back End : Sql Server
I made this program for Remote Trading.
every second server or client will be send data.
Sometime Server send data only to specific client, so when client logon to application, I save the IP number and after logout i clear the IP
the problem will be happen when the computer client Hang, server cannt send a data to that computer, and waiting for ever until server hang too after that all client will be hang.
and the question is How to check status computer already ON or Off
i mean before server send data, server will be check status computer with that IP, If status computer On then True else False, so if computer client off, server don't need to send data.
thx

I currently have details of my clients in a table called tblSites, this tble includes a field with an email address. I currently produce a invoice which is automatically saved as a pdf and an email generated with the invoice attached. However, a few clients do not have email addresses (these are sent by post). My code (see below) will successfully produce the email with the attachment, but if the client does NOT have an email address in the tblSites it comes up with the "Invalid use of Null" error. What I want it to do is continue the process of just saving the invoice with a Msgbox stating "This Client does not have an email address etc etc.
'Save Invoice as PDF and annotate Invoice Number, Date and site name
Dim StrFile As String
Dim slSQLString As String
Dim rsEmailAddress As Recordset
Dim slEmailAddress As String
StrFile = "C:Redwatch Invoices" & Forms!frminvoice!txtInvoiceNr.Value _
& "-" & Format(Date, "dd-mmm-yy") & "-" & Forms!frminvoice!cboSiteName & ".pdf"
[Code] ....

Using VBA (in Access), what code should I use to check if a client name already exists in a table.
Say, client name is "Smith", my table is called tblClient and the field name in the table is called fldClientName.
I just need to do the check, that's all.

How to use VBA..... I have set up a simple database to enter data into then upload to a client web portal.
I have a form to enter the data and the table this data goes into has a check box at the end which I want to have ticked/checked/True after I have exported.
I have created a query that shows me all data that is unchecked (not yet exported to an xls)
I have created a simple export macro that sends the query result to an .xls
I want the macro to finish by checking the "export" checkbox once I have done this....
I am using Access 2010 attached is a screen dump of what I have so far....

Hi all
Brand new on here and desparate for some help and guidence.
So far with Access I have just used it as a store of addresses to mailshot prospective clients.
However, I now need a more complex database and this is where you might be able to help.
First things first, most of my clients are in universities. This means that I can be used by more than one person in more than one department at a university.
Does this mean I need to do three tables:
1/ "University Details" which gives the address details
2/ "Department" storing the departments of the unis we work for
3/ "Client" Name of the client(s) in that department.
After this how do I link them?
Thanks

Hi
I don't know ASP at all, and I know very little about the Internet.I do know JavaScript and VB6 among other things, so I am not a complete dummy.
I have a webpage on a webhosting company's ftp (they host asp) and my html file is working, but my asp file won't do anything (should I be calling it with the javascript from my html file?).
What I want to do is make a list of the top 10 players of a game.
My questions:
1. how do i get my asp to display anything?
If I use my winXP IIS I can view ASP files. But from this ftp the computer just asks me if I want to run the file or save it and then opens my interdev program. Please help before I throw this computer out the window and I don't get to see your message.
2. Should my access file be 2.0 or 7.0 or whichever?
3. I use this code (from a tutorial) to connect to a database,
but it doesn't work.
[code]
<%
Set Conn = Server.CreateObject("ADODB.Connection")
Conn.open "DSNname"
%>
What is DSNname?(In VB6 it is the name of the data control), but there is no such thing here, is it the mdb file name?
I think I will have many more questions but for now I'll stop here.
Thanks

After 2 days of searching I am sick too my stomach from not finding what I needed. I simply do not understand how it is possible that everyone, including Microsoft, assumes people just know stuff.
I have been wanted to read text files within an Access DB. The DB will extract key words and store them into fields. This is all very simple if I could get the rotten VB to read the files. I wanted to use the object My.Computer.FIlesystem, and all the others associated with that library. But going through the hundreds of possible references, I haven't a clue to which one has that library.
No matter where I went too look, not a single line, post, page listed how to reference it. Only how to use the function. So frustration.
My current reference list is as follows:
Visual Basic for Applications
Microsoft Access 11.0 Object Library
OLE Automation
Microsoft DOA 3.6 Object Library
Microsoft ActiveX Data Object 2.5 Library
If someone can please help.

Hi,
My question is...is there any way to get Access to work out the actual day of the week from a date entered into the computer? The reason for this is...I am designing and implimenting a bookings data base for a village hall, and I wish access to automatically store what day of the week it will be on the specified date, in a field called 'Day'. I need this field to produce a report for the week ahead, showing exactly what is in on which day of the week. Is there any way this can be done? Or do the days just have to be typed in manually, i.e. check a calendar and type them in? I would appreciate it if anyone could give me info...on ANY way this can be implimented...be it store the dates in a table or use a giant Iif statement or whatever! And the tags necessary would be helpful,
Thank-you for your help in advance, and i apologise for such a lengthy post!
Please get in touch directly through c.majury@ntlworld.com or alternatively post the answer here.

I am trying to create an Access database that can be used to configure computers for sale in a small pc repair shop.
What i need it to do is have drop down boxes for different parts, each part having a value, and at the end being able to update the total value depending on which parts are selected.
I have tables with different types of CPUs, Motherboards, RAM, etc etc... each table has description and price values ( a couple more for relational stuff but i don't think that is needed to figure this out ) Just to test it out i have a form where i can go through and select the different products, but i am stuck on the adding of values of the different computer parts.
So anyway, i am trying to take prices matched with values from multiple tables, then add the prices all together at the end for a total value, like any of the pc configurators online.
If anyone can help, greatly appreciated, if i make no sense just ask to clarify...

In my Frontend, i use parameters like:
1) computer name
2) a certain file's existance
So i'm sure that the front end is being run on an autherized computer.
i have hardcoded these values in the vb code and password protected the project so that no one knows about it.
what other parameters can i use to stop the front end being run from any other computer else than thoses allowed.

Hi -
I have a form used to enter criteria for display of records on a subform. There is a refresh procedure that is used to update the subform. This procedure is called on load as well as after changing any of the criteria.
This has worked fine on multiple computers running both Access 02 and 03. However, one of my clients has a machine that seems to choke on this procedure. I get the following error message -
"2455: You entered an expression that has an invalid reference to the property Form/Report"
The procedure called is:
Private Sub RefreshSubform()
Dim strSQL As String
strSQL = "SELECT * FROM qryProjectsCases"
If Not (IsNull(BuildFilter)) Then
strSQL = strSQL & " WHERE " & BuildFilter
End If
' Me.frmsubProjCases.Form.RecordSource = strSQL
' Me.frmsubProjCases.Form.Requery
Forms!frmCaseList!frmsubProjCases.Form.RecordSourc e = strSQL
Forms!frmCaseList!frmsubProjCases.Form.Requery
End Sub
The error occurs at the line where I try to set the record source property for the subform. Note there are two commented lines, this was the original code and experienced the same error. Both methods of referencing the form generate the same error (on this one particular machine - both work on the other machines).
The function BuildFilter generates a SQL string based on the various criteria on the main form. I have even tried setting SQL to a constant, but still get the error.
I have checked to see if the References are complete, but don't find any missing.
Any suggestions?

The problem I having is if I have a computer name of a computer on our network (not the one I am running the database on), is there a way using VBa to find the details about this machine.
For example if the computer name is 'DTP002133' I can click 'start' then 'search for files and folders' then click 'computers' in the search for other items. This search will give me the computer location and comments. I would like to be able to automate this process within my database.
Not sure if this one is possible but thought I'd pick you brains...
Thanks

I have a database built using Microsoft Access 97-SR2. I want to copy it to another computer (my office computer). I was successful in burning the file to a CD-R disc. However, when I run the database from the disc, a message appears saying its READ ONLY-it apparently makes it Read Only automatically. I want to be able to change and edit the data and the controls, ie. forms, reports, etc. on the other computer. How can I transfer the database my other computer, without it becoming Read Only?
Any help would be appreciated

I have hyperlinks from within Access forms that link to Adobe PDF documents; these are the new PDF Package documents created with Acrobat 8 - and give the message "Multiple files are bound together in this PDF Package."
The problem I am having is that when ever I click on the hyperlink the computer hangs (from the task manager, I believe that it is Acrobat Reader that is hanging). This problem only occurs with multi-file PDF packages and does not occur with regular PDF's. It also only occur with MS Access, as linking to theses files from MS Word encounters no problems.
Is anyone aware of a fix for this?

I have been searching and found a few great threads about checking users but the codes there were incomplete. Is there a way to effectively log a user's name & computer name when they open your database and also log when they close/exit your database. Without them noticing but just for your own personal security incase something happens and you would like to know who all was actually working in/on the database at that specific time?
Or just something that will show me who is in the database so I dont' have to keep seeing network333 something has it open.
Thanking you all in advance, and I know I am a P.I.T.A.!
