I need to add some code to our access 2002 database to test incoming files for bytes, zero byte files in particular. Our system will then pick out the zero byte files for emailing to our customers. Can someone provide code for testing for bytes or provide me some direction on this matter? Thank you!
View RepliesI have a split accdb in Access 2010 with tables/data in the back end file (stored on a network drive) and the forms, queries and code in a front end file stored on each desktop. Note the front end file is common to two back end files. Both back ends will be mirrored but I need to use one for live data and the other for development and testing.
I want to be able to include vba code when the front end is launched that prompts the user to choose between one of two back end files, one 'test' and the other 'live'. But I've spent all afternoon scouring the net with no success on something simple but effective.
As I see it I just need an option on a form and depending on which is selected the following happens:
- links to current/existing tables are deleted
- chosen back end file (test or live) is selected (this has a password)
- links to the tables of the chosen file are created in the front end
- the appropriate back end source is now working with my front end
my issue is i have multilble text box in my form & based on change in one of this text box i need the code to compare between data in the form & table & returm Msg if it is not matching. attached screen FYI.
i look in the internet but i could not figuer out the VBA code since i do not know VBA. what comes to my mind to to use select case.
So I found this video (youtube.com/watch?v=FTjyuSTcTII&spfreload=10) and followed it to do a query for all upcoming birthdays. The video shows how to do it for the next two months and I tried to modify it just for the next 7 days. When I tried to run it, I got "Date type mismatch in criteria expression" error. I tried putting it back in the criteria she had, but still got the same thing.
At 6:53 you can find the code she used for the first table (basically asking when their next birthday is) and at 9:57 is the code for the criteria. Below is my modification.
Between Date() And DateAdd("d",7,Date())

I have to write a code for my database,i have folder with files "pending Review" and a table with column "tblExcelLocation". when i run my database all the files from pending review folder goes to "tblExcelLocation" on a click of button.But,if the files already exists it should not insert those files and insert the rest.For this i tried to write a code but i think i m unable to do that .
Code:
Loop through files in folder

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

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
Every hour a zip file is created in an FTP folder. The zip file contains an .mdb access database file with any changes to the data since the last hours file.

Can any one do this i need it real fast let me know!!

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.
View 3 Replies View Related 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?
Can someone tell me the VBA code for testing whether a query recordset is empty or not?
