Port Database
Mar 3, 2005
Hello,
I have a lotus datbase at work and there are far to many conflicts with XP. I am trying to make an access database but keep getting as far as the calculations and then give up.
I have a ships data base. I am trying to calculate totals for each vessels cargo.
Some vessels have more than one cargo. eg A Shell Oils vessel may have Diesel, Unleaded or Leaded Fuel on the one trip.
I have been able to get these totals to work b4 but I forget how I did it. If I calculate Cargo1+Cargo2 + Cargo 3 I get 100200300
The other problem that I have is that the totals do not appear in the corresponding table and so I am not able to use totals in query or report.
eg Form Cargo Cargo Tonnage 100
Cargo 1 Cargo Tonnage 1 200
Cargo 2 Cargo Tonnage 2 300
Cargo Total 100200300 :mad:
Am I going about this form in the correct way or am I totally going against the grain of access?
Any help would be appreciated.
Thanks
Mr Wheeze

MSComm7.Settings = "9600,N,8,1" ' 9600 baud, no parity, 8 data, and 1 stop bit.
MSComm7.InputLen = 0 ' Tell the control to read entire buffer when Input is used.
MSComm7.PortOpen = True ' Open the port.
MSComm7.Output = "AT" & vbCr ' Send the attention command to the modem. Ensure that the modem responds with "OK".
Buffer$ = Buffer$ & MSComm7.Input ' Wait for data to come back to the serial port.

I have a few questions which I hope you all can help point me in the right direction.
A little background is in order. What I am trying to accomplish is Read the NMEA string passed to the Com Port 1 of a laptop from a Trimble GPS Unit. Once I have the string I need to parse it ang place the Lat Long in a couple fields in my Access Database. First off I have to capture the string from the Com Port.
Does anyone have any suggestions of where I can start to learn the code needed to read the Com Port 1 to retrieve the NMEA String pushed from the GPS Unit?
How can I do this from within an Access Database?
If I can get the string returned to a variable that would be great. From what I heard other people were writing this to a file?
Any help would be appreciated.
Thanks,
Jay

Is it possible enable and disable a usb port via vba?
An example of using this would be if I had a light plugged in a usb port and the code would turn it on and off.
Or maybe is there s some device like <PC-Some Device-USB light > which can be controled by vba

I'm trying to set up a simple query that links four tables. However, the tables are extremely large, all in excess of 1.5GB each so I had to split the tables up into four separate DBs. I've tried the following with no success:
1) Link the 4 tables in the DB which contains my primary key. This quickly inflates increases the file size above 2GB and won't let me go any further.
2) Build a remote query to connect the four tables. This looked promising until I tried to run the query and it became evident that it only knows to point to the last database source that you specified.
I'm running everything locally on my C drive. The data source are simple text files (1.6 million rows) from the FDA website.

Database: Access 2007
I have designed a touchscreen input system using Visual Basic.net and this writes to an Access Database. Each Touchscreen has its database locally so it can still work even if there are Network problems.
Now what I would like to do is have all these local databases write to a central database say every minute but only write new records to the central database. The Central Database can either be Access or SQL.
What is the best way to do this?

I have been working on a database for over a month now, and my boss just threw a monkey wrench in my work. I believed that the Metal Market Prices would be entered once a week in the current DB. My boss informs me today that he wants an employee to go in every morning and enter that days Price for Each Metal with respect to many different markets.
There is a total of 12 metals, and 5 markets. I need the data to be stored first by date, then by either market or metal, and lastly by which ever isn't used second (Either: date-market-metal, or date-metal-market). I think the Latter of the two methods makes the most sense. Is it possible for my current DB to lookup values from the Metals Database based on date-metal-market?

I have a problem that seems to be happening on several users' databases and is causing a big problem. None of the databases is a shared database...they are all single-user databases on stand-alone computers. I have tried looking for help within previous posts, but all seem to be related to shared databases.
I am getting an error message: "The Microsoft Jet database engine stopped the process because you and another user are attempting to change the same data at the same time." The database cannot be opened, imported, repaired...nothing seems to work.
Again...these are NOT shared databases. I appreciate any help I can get. I created the database for all of the secretaries in our school district to keep up with absence data. It involves many tables, queries, forms and reports, and has generally worked well. However I am now seeing several that are getting similar errors as mentioned.
Thanks!

I'm new to Access and VBA, for the record. What I need to do is copy a SQL database (table structures and records) and save it as a local Access database, so that the user can query and make any changes on the local file without editting the SQL database.
Looking around, it seems like the best option would be to use the TransferDatabase method with the acImport option. Does this sound reasonable, or can someone with more experience suggest a better way to go about it? Thanks.

I created a database with forms, querys, etc. Now I was thinking of creating a exe so everyone can use this database without having access to all the design functions.
the only problem I see about doing this is if we need to use the same database for different project, we need to always create a new exe for each project.
Is there a way to make a empty database exe with just the layout, querys etc but with no data on the tables and have a save, open and save as option. So we can have several projects using the same database?
I was thinking to create a VB code for the database to delete all data on the tables when the database is open.
and before closing the database exporting all the data to a txt file or something.
Then the next time someone opens the database goes to the main form which has a open bottom which imports the txt file into the tables.
This way we can have several txt file for several project and use always the same exe database.

I am working on a database that will be an addition to an existing one on the company server. However, to make the overall layout not so complex and allow room for other additions in the future, I'd like to keep the databases separate. This will also ensure more efficiency, integrity and troubleshooting overall.
Does anyone know how this is done?
Thank you in advance for your help,
~Kilch :eek:

I have a car dealership database and have a servicing section.
I want to create a form to service these vehicles.
The only vehicles which will be displayed on the from are the sold ones (because you cannot service a vehcile which hasnt been sold) which i have a query for.
I also want the form to display the customer who owns the car the service details (eg what they need), the parts availiable and the parts required for the service.
The calculations i need to make in this form are as follows
quantity needed (parts required table) - quantity in stock (purchasing customer parts table)
quantity needed (parts required table) * price (Parts Table) + labour (servicing table) = part/labour costs (servicing table)

any suggestions on how to do this would be fantastic

Hi all,
I was playing with passwords for one of my access db.
I tried opening the db with the password, but it won't work. So, I thought I forgot the password. I checked some posts on this forum that helped in retrieving the password and it's the same that I have been trying. I am not sure if the Name is correct, is there a way to retrieve the log on name?
I also noticed that when I try opening any other db on my system, it asks me to log on, I though I was only applying a password to one file.
Please help
Thanks!

I have been tasked with setting up a database for all employees the info contained is along the following lines:
Employee Number:
Name:
Qualification Status:
Qualification Run Out Date:
To name but a few of the parameters
I have currently set up the start up screen, main switch board and the complete employee records table with form (for simple viewing/input).
My problem is this we have four departments that require access to the database
Admin - Require access to all employee records (View)
1 Dept - Require access to their employees (View and update records)
2 Dept - Require access to their employees (View and update records)
3 Dept - Require access to their employees (View and update records)
Currently i have created one complete employee record table (Admin) how do i break this down for each department so that when the info within each one is updated it in turn updates the main Admin table?
I started by copying and renaming the Admin table for each department but this never updated.
Any help and info would be appreciated.
On a slightly less important note for the time being at least can i password protect each command button on the main switchboard?

Hello,
I basically started teaching myself how to use Access 2000 about a week ago. I am working on a project for work, that requires to have a report of all the training records. But my boss wants it to be color coded. He wants one color to show the people's training classes that are 45 days out from being over due, he wants another color to show what classes are due. And another color that shows classes that are over due. In my table, I have a column for the classes that show the date that they took the class, and I have another column that shows the due date of the class. But I have no idea how to go about getting the report color coded with what he wants. Any help at all would be great. Many thanks in advance.
