i designed a form in ms-access 2010 . it's based on a table . i want that when the user enter data into the form and shift to the next or previous record the last record he had been in, by default changes to read-only property to prevent the user from editing any data by mistake
i hope the answer be by ms-access 2010 macro
second question :
actually , i googled my question before asking but i failed the real reason
when i designed a program in ms-access-vba to be used across multiple pcs , i face a big problem
the problem that the code does not work at all on some pcs unless i setup a version of windows 7 on the pc that the code doesnot work . and this solution is annoying and impractical
i hope to solve this annoying problem
that's why i ask every time from you all that answers be by macro not by vba .although i love vba but macro proved to be the alternative soultion to this problem
what shall i do?
any ideas for that problem
thank you very much in advance
There is a property you should check Form.DataEntry allows you to enable the form to ONLY add new records, but not editing.
Form.DataEntry property (Access)
Play with VBA, make the form as only to add records, and then allow users to edit records only if they click in the button to edit. That way you can prevent mistakes as you wish.
I do now know how your database is designed and how your forms are designed/linked, but what I do is loading the same form in 1 mode or another (adding or editing), depending where the user clicks. That way, for me, is easier to control mistakes.

I have been exploring Azure Form Recognizer for one of my project where we wants to perform OCR on some hand written texts.
The problem is that when we give scanned images to the tool to process, it some time doesn't even recognize the text written on it (even if it is clearly written). I tried multiple type of images by performing enhancement on it and also the B/W or colored copy of it but it doesn't works.
Some times it recognize value of two fields as one and this leads to incorrect data where one field is completely blank and other is having value of other one along with its own.
When there is NO VALUE in the tagged field in the testing data, it try to read the from some other place which is not even closer to that field or sometimes un-tagged
Could you please help with these queries.
Thanks in advance.
Can you please share also sample forms please make sure data is anonymized and without any real data ?
Please contact customer service to debug this issue.

Apologies if this has been asked/solved before. I've done a fair bit of searching but can't seem to find a direct answer to my problem.
I'm still very new to asp/vb coding.
I've created a complex calculator in asp.net using vb.net.
The user fills out a few text boxes with information then clicks the calculate button. The program then accesses an sql 2014 server to collect more information based on information the user has entered, then uses the information to run a few very complex calculations (I don't completely understand the calculations behind it).
It all works fine and is able to give the correct answer, the problem I've found is if there is more than one user accessing the site and they happen to click the calculate button within the same time, whoever clicked the calculate button first gets an error whilst the person who clicked second gets an answer.
I'm not sure if this is to do with how it accesses the sql database for information or if the information is somehow being overridden.
I was hoping this would be a common problem, but can't seem to find anything on it, at least I may not be asking the right question when searching.
Unfortunately for security reasons I'm not able to post any code for it (I'll see if I can get permission) but am hoping that someone has come across something similar and knows a work around. Maybe to have the site wait until the first round of calculations is complete before initiating the second round?
Thanks for your help in advance!
Please make sure that you should not use any shared variable in calculation because shared variables are common for all users. Also check for application variables.
I can understand, but if those public variable's value changed at one place, then after everywhere that variable's value will be new even if you are in middle of some processing.
I am new to android and java and working on an app that has a few remaining problems that I haven't resolved yet.
I have a main activity that is a viewPager, with each page being a fragment. If the 4 fragments 3 are extended from ListFragments and one from PreferencesFragment.
The ListFragments have CursorAdapters to get data to and from SQLite databases through providers.
I am able to get data into the database, insert, modify and query the data correctly and fill the list views ok.
My preference setting are to choose different ways of viewing the data in the database.
Not knowing how to do this, I have implemented a process where I modify the cursorLoader query to the provider with a number of different choices of the "WHERE" clause. I have worked out the logic for the preferences as they exist now, implemented the code but had some difficulty finding what to try to trigger the refresh of the ListView.
Since the "dataset" hasn't really changed, no trigger can come from there, plus that would just use the same cursor as it currently exists to run the query again and return the same results (or be smart enough to know that it doesn't need to run).
On Stack Overflow I did find a couple of references to a similar implementation that suggested reStarting the cursor loader, which would then on the reStart read the current values in the stored Preferences file, create a now modified WHERE clause that will show the sub-set of data as specified in the preference settings.
In testing the app now, even with the reStart of the cursorLoader, the ListView isn't getting refreshed.
The only time I can get it to work right is restarting the app. If I stop the app and restart it, the new values are used and the ListView presents as the preferences dictate.
In looking through Stack Overflow and the Android site, I did find another set of APIs that might have been a more natural fit for what I am trying to do, namely the Filter APIs.
First question then would be, did I go in the wrong direction on how to control the "filtered" view of the datbase. Is filtering a better approach and a recommended way of
doing what I am trying to do?
Second question would be related to the fragment lifecycle of my ListFragments to achieve this CursorLoader update.
Thanks for any input on the topic.

Found my problem here.
Two things, the way I am trying filtering is working and from what I have seen in the
Android development site, a reference there indicated that the filtering capability is
already implemented in the CursorAdapter, CursorLoader classes I am using.
When my preference settings changed, I did a reStart of the cursorLoader, but had restarted the wrong one.
Problem solved. Any input on is there a better way would be appreciated.

I'm part of a team building a large ASP.NET Web Forms application, and have recently gotten complaints that some records are being "cleared out" after being created -- in this case they create an "inventory" item, save it, and then perhaps after editing some of the data and re-saving, all of the fields are suddenly blank.
I realize that this could be some faulty logic on the save, in which case it will be difficult for you to offer insight, but we've never come across this particular issue before, and haven't really touched the logic. I'm wondering if anyone has some insight into what could possibly be going on, if it's possible that something sporadically happens on the client which makes the values of the input fields blank or unreadable...? I don't know, I'm a bit in the dark and frustrated because I can't reproduce the behavior, and we're losing a bunch of data.
Thanks in advance for any bit of direction or advice.
Related issues in WebForms are often caused by logic related to Page.IsPostBack and values being reset.
Without code it's hard to say; I'd suggest adding some temporary code to log the posted data (and function calls down the line to the database writes). Without logging you're blind.
How do I delete records from a DataGrid as well as the source database in ASP.NET using a checkbox to select them?
Step 1:
Lookup how to get the references to the selected items in the grid control.
Step 2:
Delete directly from the database using the references in step 1
Step 3: Refresh the grid control / page.

In the spirit of what makes this a good programming site, it behooves you to at least try to solve the problem yourself first.
Once you have had a decent go and can provide some samples of the way you have attempted to resolve your problem then the people here will be glad to help.
Simply expecting others to gift you with a solution is not really what this site is all about.
My suggestion is to go and do some research, have a go at solving this yourself and then come back and ask a question related to the specific problem you are facing when attempting to resolve this.
