I have a wonderful database I designed almost 2 years ago. Other than a few hiccups with corrupted data (http://www.access-programmers.co.uk/forums/showthread.php?t=135483), my employer is 100% satisfied with it.
I’m graduating this winter with an AS in computer programming and I would like to update the database to a VB/ADO .NET (VS 2003) front end before I leave. Being a VB developer, I have had my fair share of “quick fixes” when I could not work out a solution with VBA. VBA is the evil twin of VB lol.
Other than PHP w/ MySQL I have never used two separate entities for data management. It’s always been strictly MS Access as the database and front end.
So my question is what major differences should I expect that I took for granted with MS Access’s built in functionality? Such as subforms with master/child properties, navigation, printing reports etc. Will I have to write code for every little detail that MS Access handled for me?
What are your thoughts on using VB.NET as a front end? Did the pros out weigh any cons from your experience with this setup? Any thoughts on using Crystal Reports?
I am currently using some of the code from ghudson's browsing2.mdb for importing XLS files into a database that I making. After pressing the import button which triggers the importing of the file it imports the contents of the XLS into a table called import and into another table at the same time. Both the import table and the other table have the same structure. For the sake of argument lets call the other table "table B".
I want to know of a way of how during the import of the XLS it can flag with a message box to say that that the information already exists in table B, and exit out of it. I was thinking this would be done in VBA. I have written some part of it (very basic) and would appreciate someone's opinion if I am on the right track. It basically searches if the same data lies in the 2 tables and pops up a message box. I would welcome any other solutions, but I would prefer it to be VBA.
----Start of Code--------------------------------------------- Dim strCompare1, strCompare2, strAppend1 As String
strCompare1 = "Select table B.field A from table B where (select import.field A from import);"
strCompare1 = "select import.field A from import where (select table B.field A from table B);"
If strCompare1 <> strCompare2 Then strAppend1 = "INSERT INTO table B ( field A, field B, field C) SELECT Import.field A, Import.field B, Import.field C FROM Import;" CurrentDb.Execute strAppend1 Else MsgBox "Piece-Marks already exist in the database, so if it is an update then use the update function" End If

Looking for some advise and help. I think an array will be recommended and if so, please help with code on how to do this.
I am trying to track prescription (Rx) dates (RxOutDate) going out to medical professionals on a particular order. There can be mulitple Rx going out so there will be multiple dates of when those Rx went out. What I would like to do is have the earlies date posted. ie one Rx went out on 10/13/04 and another goes out on 10/14/04. I would like for the 10/13/04 date to show. I'm using a continuous form to display all Rx's per order, on frmRx. I'm trying to display the date out on the form containing the order (frmOrder).
Any thoughts would be greatly appreciated. If an array is suggested. Please help with code on how to it. I've never written one so I would definitely be in the dark.
I am trying to calculate the number of weekdays between two dates in an access query.
I'm using Expr 1: DateDiff("w", #4/01/2006#, #02/26/2007#)
When I use this expression with "d" instead of "w" I get 331 days, but when I use "w" I get 47 days. I know this can't be right.... Is there something I'm missing here?
I looked up on msdn and "w" is for weekday. Is there something that I need to do to be more specific?
Im planning a db client's dinner questionaire that will comprise of client's favorites (meals, games, transportation). Each client is allowed to bring a guest. So the client's will also be filling out "the same set" of questionaire for his/her guest.
Meaning, a user will need to fill out the same form twice, one for himself and one for his guest.
Now, my question is, should i have two tables. Client's questionaire table and Guest questionaire tables with foreign key in the guest's table showing who's guest the question belongs to?
Or should i have one table for everyone (since they are the same set of questions). Having one table seem like a wise idea since it's the same set of questions (don't want to have 2 duplicate tables with only one field different). Now, if i go with one table. How do i go about handling this? So that client's and guest's info are linked. and i can run a query to tell who's guest it is? I have never tried thsi before. Care to share your thoughts?
I put a split database (created in 2000 format using Access 2003 SP2) on the network three weeks ago. Three times the entries in two of the columns have been changed for every record, essentially making the data useless. I have not been able to narrow it down to a specific event that is causing it in order to program around it. Any thoughts would be greatly appreciated. Here are the details:
The table involved is called tblTitleLog. It contains 13 columns, the first of which is an autonumbered ID field. Column 7 is called CompletedCSA. Column 9 is called CompletedDate. The data in those cells could be different, from record to record, or could be the same as several records on either side of it. The data in those two cells can be updated either of two ways:
On a per-record basis using a form that contains controls tied directly to the cells for a given record, or On a form that incorporates a multiselect listbox and an Update button. This form is specifically designed to allow batch updating of those two columns.
On three separate occasions, the data in those two cells suddenly changed for all 6940+ records. For example:
This: CompletedCSA CompletedDate Timmy 2/2/2008 Bobby 2/5/2008 Joey 2/10/2008
Would suddenly change to: CompletedCSA CompletedDate Bobby 2/5/2008 Bobby 2/5/2008 Bobby 2/5/2008
No warning messages about multiple people trying to change the same record(s) is displayed. None of the users have been able to spot a trend in something they were doing when it occurred. The code for the Update button on the batch update form only changes the records with the ID of the SelectedItems.
This is the code from the Update click event on the BatchUpdate form:
For Each i In Me.listboxTitles.ItemsSelected strWhere = strWhere & Me.listboxTitles.ItemData(i) & ", " Next
If Len(strWhere) > 0 Then strWhere = "WHERE ID IN (" & Left$(strWhere, Len(strWhere) - 2) & ")" End If
Duplicating the same actions the users reported just before it happened didn't seem to make a difference. So far, I haven't been able to duplicate the conditions. Management is not happy and I'm frustrated. Any thoughts or suggestions on how to prevent this from happening again?
Hello i want to use as a front end as i can create better forms etc... i want the end user to enter information into a form in Flash and then it automatically updates the access back end? is there a simple way of doing this??
I have read every post here on "distribution" and "deploying" the front end to the users but can't seem to get how to do it. I see many posts regarding updating the front end and using the runtime version to distribute but can't seem to understand how to initially get the database out to my users.
I have a split db and need to distribute it to about 20+ people. The back end will reside on a shared drive that is mapped the same on everyone's machine. I also have the FE on the same drive and am currently using a batch file run from a link on our website to open it, therefore we are all using the same front end which is what I am trying to eliminate.
Can I just zip up my FE and email it to my users? Will that maintain the links to the back end when they unzip it to their desktop?
Also, I would like to get some feedback on some software I am thinking of buying for pushing out my updated databases in the future. It is called Access Frontend Loader http://www.frontend-loader.com/
Has anyone used this before? Would appreciate any thoughts on it or any other program you may have used in the past.
I am trying to create a Preventive Maintenance Program for my facility,
I will create maintenance tasks: [ID],[Dept.],[Machine],[Task],[Frequency],[Completed Date],[Due Date]
Simple tasks,
Up front design help,
I will want the task to stay in the task table and the Due Date to be calculated combining the [completed date] & [Frequency]
Simple not a problem,
Here is my problem: I will need to create a task history table that will contain the Task details and the Completed date each time I complete the task; therefore my thought is that i will need to send the task detail to a history table each time it is complete, so I thought Append Query; but the problem is that it appends all of the records in the task table each time you run it including the tasks that have been appended on previous query runs.
any thoughts on how to capture the task details for a specific record and send them to a history table ?
I have a split database, the front end is showing to be 20.5 megs in size but there are only 4 forms and about 6 querys. Can someone tell me how to find what is making it so large?
I did a compact and repair but it did not reduce the size??
I think I am having some problem with my back end and frond end files. I have a mde file that anytime I enter new data or change some things in the old clients file, it does not update on the mdb file. Anytime I need to change forms or report or any thing at all, I am suppose to copy the BE file and the MDB file to my workstatio, remove the table link, make the changes I want to make on the design mode and then import the files back to the live copy of the mdb file then make another mde file to work with. But When I copy the BE and the MDB files, I don't have the updated client list or new client just added. So as not to affect other users, I can not make changes in the MDE file and even the MDE file will not even let me make any changes in design mode. I don't know If I am making sense but any help will be appreciated
I am having a trouble with a multiuser DB. I have split it using the Splitter Wizard and have put a copy of my FE to a second computer and relinking its tables. When I opening the bound form in computer 1, computer 2 can not open that form and sometimes computers lock and had to restart the machines. But if I open that form in computer 2 first and then the same form in computer 1 , it works fine. I have set full sharing to computer 1. I am using Access 2007 and Windows VISTA.
Both have FE, the BE is located in a shared folder with full permissions in C: in computer 1, the FE of computer 1 is in that same folder. Both computers are connected via a Cat5e Cable.
FE in computer1 table links to c:databaseBE and computer 2 links to computer1_IP_Addressc:/databaseBE
Hello I'm looking for a web based front end to put on my access database. Due to the way our work site is set up and the people who will be entering some of the data my boss wants it to be accessed through a web browser. Infopath wont let me enter data into an access database through a web browser and with DAPs becoming a thing of the past we dont really want to use them either. Some of the forms will be used for raw data collection while others will be used to fill out spill reports (i work in an environmental department) so we can get the information quickly. We have tried just using access to run everthing but have meet alot of resistance as most of the people who enter the data hate it. I also had someone enter half a spill report into an SQL sequence once..dont even know how he got there. That is the main reason we are looking for a web based data entry system. I dont believe my boss wants to use anything but access for the storage. So basicly we are just looking for a way for people to use a web browser to enter data into an access database. Any advice would be greatly appreciated. Thanks
I have a backend database and front end mdb file with forms. I established the necessary relationships in the back end, however when I open Relationships screen in the front end - it opens empty. Do I have to establish same relationships in the front end or can I leave it as it is and still have my relationships work as defined in the front end?
I've one FE & BE related question here. Ok first of all I've BE in server and each user have copy of FE in local PC. But I've one problem with linked tables between FE & BE.
Is there a way that FE can programmatically create connection to BE linked tables or user is able to link those tables manually, if FE can't find/connect to linked tables in BE? Or do I just have to manually configure each users FE linked tables?
All replies are welcome and well approciated at all costs! :D
I want to use access 2007 as a front end for Sql Server DB. I want to create a basic input form, a search and display facility, and have some reports generated out of the application.
If this would be possible to do using Access in 20 days?
i am creating a database that will house some supplier information. once designed, the db will be populated with all the data and then it will be used as a reference tool for future projects.
it was requested that an "excel front end" be used for lookup and ease of use to access the data when it is finished... i am not really sure how that works.
also, what is the best way to create contingent variables in access-- for example, if a certain value is in the database then you have a corresponding action. like if there were a field asking how many suppliers there were, and if say the number is 4, then 4 entry windows come up. a sort of if/then statement?
I split my database so that users could only edit/view data through the forms but when I opened the front end the tables where still there (linked though) and I could edit and look at them. I assume this is normal so how can I prevent users from seeing the tables. Do I just set them to hidden? Thanks.
I have a DB that I just distribute a shortcut to a front end on a network location. Then when I update the front end I delete the old one and give the new one the same name as the old one, so everyone's shortcut still works, but the FE has changed.
I haven't seen anyone else do this, which makes me nervous. Can you see any potential problems with this strategy?
I have Microsoft Access on my desktop connecting to a MySQL database at my host, using an ODBC driver. I can read the data just fine. But when I try to add another record, it won't seem to do it.
Is it possible to update a MySQL database from MS Access on my desktop?
I have just one table. Very simple. Is it to do with primary key number generation or something?
Hope this isn't too silly, but I've just discovered "decompile". Instructions don't mention back ends and front ends. Do you have to run decompile on the FE and again on the BE, or is it sufficient to do it only on the FE (which has links to tables in the BE).
I have a db that I have split out into a front end and a back end. The back end is on a network drive, and I have a copy of the front end on each user's computer.
The issue that I'm having is that 2 people can open the front end and 2 cannot.
When the database opens I have a form that loads on startup with a username/password combo.
On the 2 machines it works on, everything loads flawlessly, on the others they get an error message stating "\networkpathaccess.mdb" is in use
I am running an Access 97 database with the backend on the server and client databases on about 2 workstations. I also have a working model of the frontend on the server that I often update. I then have to go around to each workstation and manually install the new front end from the server. I am looking for an application built in Access 97 that I can apply before the client database opens, it checks the client on the server and if a newer version is available, it copies it to the workstation. Once copied, it then proceeds to open the new front end on the workstation. Tony Towes has an excellent application on the Granite website but I cant use it because it contains a VB programme that I cannot import onto our network (security restrictions).
Grateful if someone could point me in the right direction.
