Test For The Existence Of A File
Mar 3, 2006
If i hold a record in a table with the path and file name held in one field, is it possible to code Access 2000 to check that this file exists? I want the database to perform a certain action should it not be found.
Any help most appreciated.
Many thanks

hi,
I have an ActiveX control which needs to be registered the first time a user opens the database on a machine.
Is it possible to run a query/autoexec or similar on startup which informs the user if this particular ActiveX control isnt registered?
Our company is undergoing an OS upgrade and it would be useful to inform the user to register the control if not done..
Thanks in Advance

Table is named tblLVR
Field is BusinessName
I want to check the previous existence of this name in the table.
I assign a variable tBusVar to the entered name on it's changed event
and write the following code to see if it is already in:-
If DCount("[BusinessName]", "tblLVR", "[BusinessName] = " & tBusVar) > 0 Then
MsgBox "This current record is a Duplicate"
End If
Run_time Error :'2471' : The expression passed as a query parameter produced this error '<Name entered>'

I have some code that will run if I am populating an empty table(no duplication's possible) but now I am trying to create a Sub to check for existence of a record and handling it going forward.
Anyways the big picture is looping through a text file and placing data where it needs to go. The code follows including some comments point to the issue.
Code:
Sub PutinNewTag(TableIn As String, Tagtype As String, textline As String)
Dim strSQL As String
Dim NameIn As String
Dim TagName As String
Dim Db As DAO.Database
Dim rstin As DAO.Recordset
[Code] ....

Hi Folks!
I've been asked to make a 5 questions test to evaluation potential new employees' knowledge of MS-Access. Honestly, I need your input on what to ask. The goal is not to make a very hard test, but rather to see if somebody as at least basic knowledge of SQL and Ms-Access.
Some background information of what we do with MS-Access
We use MS-Access as a central hub for different download from different systems. We make a lot of daily imports. We export queries in Ms-Excel. We open it from Access and format the report. We make hundreds of reports every day. We don't really use forms or reports.
What questions to ask?
I was thinking of having 2 questions about SQL. One simple query with a formula, and a query with 2 tables (perhaps a left join). On what should my other questions be?

Hey all, I'm trying to design a Test / Survey database.
I have posted regarding this problem before if it looks familiar to you.
Please look at the .jpg attached
I have looked at some previous survey/tests design posted on this forum and had a good table design based off of a Pat Hartman suggestion. Now i am wanting more out of the database and need more advanced options.
The main problem is how to tell which answer/OptionDetail is the correct answer for both Surveys and Tests. Maybe it would be better to separate the two? All suggestions welcomed.
Case Survey
Here is what i am trying to do. When a user decides to make a new question for a survey they will have to choose what type of question the question will be. For example say the user wants to make a survey with a answer grid question. They would choose Answer Grid from the tquestionstypeMaster combobox. Then they would have the option of choosing a type of answer grid (Satisfy3) from the tQuestionTypeOptionsMaster combo box. Say the user chose Satisfy3 then they would be presented with a list of all possible answers that the test taker would see for the Satisfy3 choice ( Very Satisfied, Somewhat Satisfied, Not Satisfied).
This is what i want as far as the survey section goes.
Case Test
A user decides to make a new question for a test they will have to choose what type of question the question will be. For example say the user wants to make a test with a Multiple Choice question. They would choose Multiple Choice from the tquestionstypeMaster combobox. Then they would have the option of choosing a type of answer grid (Single Answer, Multiple Answer) from the tQuestionTypeOptionsMaster combo box. Now comes the part where im stuck. I have to somehow get the Multiple choice selections that the test maker is entering into the tAnswers table and figure out how to tell the program to look at tAnswers insted of tQuestionTypeOptionsMasterDetails when the test taker opens up the form. I also need to figure out how to tell which multiple choice selection is the correct answer.
I hope this makes sense to everyone.
Thanks Hooks

I need to evaluate a string, if the string is ?-* or ???-*, then I return the string, if not I use the Left function.
I would like to do this with IIF statement in my query, or a VBA function that I could place is my query.
This is what I have so far:
VBA:
Function change()
Dim str_sku As String
If str_sku = "???-*" Then
str_sku = str_sku
Else
str_sku = Left("str_sku", 5)
End If
End Function
I get a type mismatch error. I tested on change(Function change(983-00245)
In the IIF statement, I am not able to figure out the Or part.
SKU: IIf([ITEM] Like "???-*",[ITEM],Left([ITEM],5))
Missing the "1-*" part.
Any help would be appreciated.
Thanks

I have offered to help a local school ICT Dept with their A level projects. the first database they send me and I can't get further than the sub menus.
I would appreciate any assistance as I don't know wether it is something I am doing wrong or something within the structure. I've opened it using the Shift key to look at the code and can't see anything wrong. Any help will be very much appreciated. Regards. Bernard

Hey all,
So I'm pretty much done with this database project, but I've got a few minor snags... 3 actually.
1) get error when use delete button and select any option other than "yes"
2) my listbox selection does not load the record in the main subform area as it is supposed to (but I think I just don't know how to set this one up)
3) the frmAdd does not allow user to enter values into the fields for some reason, don't know what's up with that one
If anyone could take a peak, check it out, let me know if there is anything I need to fix, or more importantly, how to get those above things sorted out. It would be greatly appreciated. thanks in advance

I am trying to create a field that will calculate a persons age at the time of a test date. I have the DOB field that gives for example :
3/10/1993
Then I have a field that turns this into the Age in Year and months
14 yrs 0 mos
I have a TEST Date field that tells me when they took the test:
10/1/2001
Now I need a field that will calculate how old they were at the time they took the test. I tried using this formula:
AgeAtTest([DOB], [TestDate])
but then in my field I am getting this : #Name?
It should calculate them to be: 6 yrs old at the time of the test. How can I make this happen?
Thanks!

I'm not looking to spam anyone or sell their data but need help to test a simple market research system that i have built. I'm looking for about 25-50 people to let me send them an email inviting them to a webform to see if the "process" works correctly from start to finish.
The form asks for limited data about people but nothing that can identify them personally. Just gender, age group and postcode prefix.
Can anyone who is OK with sending me their email address to enable me to test this please send to:
mailconnection@dsl.pipex.com
Your help is greatly appreciated.
Thanks
Vince

Is there a way of doing a logical test to see if a filed has a "#Error" instead of a value?
If so what is the expression and syntax?

1.) What is the File Extension associated with Microsoft Access database files?.........MAF or MAD
2.) A Field Name may contain a maximum of ________ characters.
3.) A ____________________ determines the kind of values that users can store in a field.
4.) A Field Description is required for all data fields......T/F
5.) Use of Field Descriptions dramatically increases the size of the database and, in general, should be avoided.....T/F
6.) FirstName, PhoneNumber, and ZipCode are fields which typically include an Input Mask.......T/F
7.) A Field Name is required, but a Field Caption is optional.....T/F
8.) A 5 digit Zip Code should use this Data Type......
9.) An INDEX speeds up updates, but may slow searches and sorting on a field.......T/F
10.) A Default Value is a value that is automatically entered in a field for new records......T/F

Hi all
I have a bunch of student test scores. The test is scored out of 100. I want to COUNT the scores (ie I want to know how many kids scored 50 etc...). This is easy enough except the crosstab query will be very wide ie 100 columns.
I cant seem to reduce the size by grouping them into ranges (ie count the number of kids that scored between 50 and 60 in a cross tab. I've tried variations with select queries but without luck.
Maybe there is a way to code it.. and then show it on a report??
Any ideas?? Thanks

I have some code to delete a record from a table, which does not delete the record, presumably because of referential integrity settings. That is fine of course, that's what should happen. However I want to be able to notify the user if a delete did not succeed. How can I check this? I tried this code, but it did not return an error.
Code:
strsql = "DELETE * FROM " & tblAddress & " WHERE GenAddressID = " & Me.tb_edtID
Err.Clear
CurrentDb.Execute (strsql)
If Err.Number <> 0 Then
MsgBox (Err.Description)
End If

For example say the user wants to make a answer grid question. They would choose Answer Grid from the tblquestionstypes combobox. Then they would have the option of choosing a type of answer grid (Dual Scale, Rating Choice, Ranking Choice) from the tblQuestionOptionTypes combo box. Say the user chose Ranking Choice then they would be presented with a list of options for the Ranking Choice. For example 5 sets of rankings, 4 sets of rankings. 3 sets of rankings. (These are just coming off of the top of my head but i think you know what i mean.)
Question, Is this close to being correct. mind you i have just started this and am just throwing ideas around.
Where could i store the correct answer for each question. Sometimes there will be a answer and sometimes there will not be an answer due to the fact that it could be a test or a survey.
Any help or suggestions would be appreciated. Thanks

A form with a text box expecting a date has the validation property as, >#1/1/2010# And Is Not Null. If a date is entered older that this the error is caught however if the field is left null it is not caught as an error. I have tried several modifications of this statement with the same results.

I've gotten to a point with my database where I have split it into front and back ends, and then made a copy so that I have a test version and a live version. I have users in live who've started keying data, and I'm working on forms and tables in test that I then copy to live as they are completed. Up to now, I've been just copying the individual item in test, and then pasting it over the version that exists in live (example: I made some changes to a form in test, copied that form, and then pasted over the version of the form that was in live).
Where it gets tricky is that I am also in the process of designing and insurance underwriting feature that's going to be a part of this application. I've set up all the tables in test, and now that I'm working on setting up the relationships, I'm wondering how I'm supposed to copy the relationship setup into live. Am I supposed to be copying the entire front-end from test when I have changes, and replacing the existing "live" front end with it? And if I do that, will I have to edit it every time to keep the new live front end from sending data keyed into it to my test version (had that happen when I initially split it)?

I am looking to create a database that collects data from past tests, predict probable future score, and compare to goal score. Currently I am studying for the Bar Exam and want to track (in all 7 subjects):
-my current scores for practice exams
-prediction of what my score will be on exam day
-comparison of actual and goal score
-comparison of predictive and goal score
-all of the above, separated by different types of Tests for each subject
Below is an example of the type of data :
Ex: Civil Procedure--06/15/15-Kaplan questions-> 6/10 (60% practice score)-> (predict gain 1 point 70%)-> (actual exam goal 20/28=71%)
Civil Procedure --06/15/15--past MBE questions->7/10 (70% practice score)->(predict gain 1 point 80%)-> (actual exam goal 20/28=71%)
Also from this data I want to generate graphs
Would this be possible in Access? Should I use excel instead?

I have attempted to create a test environment, by creating a blank database in SQL and restoring a backup of the live environment over the blank database (now called test db). I then took a copy of the Access MDB file,and renamed this to testMDB. I then created a new ODBC link to the test db and refreshed the links to the tables by the importing the tables.
Majority of the system works, but I have noticed that after doing this, the forms that access some tables appear to be 'locked', in that no additional data can be added. The page effectively looks greyed out. If data already exists on this tab, then it can be viewed, but cannot be edited. In the live environment, the form shows an additional line is so that more data can be entered if required and any existing data can be amended.
I have attached two screen shots showing the difference.

I have been trying unsuccessfully to transfer about 20 details describing the name, up to 14 different colours, prices etc and one image of beads from the details displayed on a form to a report. I have no problem displaying the details of one bead using a combo box but then I want to send these details to a report. After that I select another bead and then want to send these details to the report.
The report is divided into 12 rectangulars to represent 12 sections of a display box. This tells the shop owners which beads to put in which section as display is important for sales. as there wooden beads, glass beads, plastic beads animal beads, letter beads etc, etc.
I have gone into this details so you will understand what I am trying to do. I would be very grateful for help but I am sure will realise that I am technically inept and please when you try to explain things to me to remember you are dealing with an idiot.
