i am developing an app for windows in vb net.
I am stuck in the last part which is the following and i would like some help on to where should i look or do.My question:I have one database in mysql called patient.each patient have the usual columns(name,surname etc..).Apart from all the columns there is one column called 'time' and another one called 'date'.I have also one datagrid where these values are displayed.When a new user is to be added,all the fields are filled and in the 'time' he fills the time of visit.I would like to ask if there is any way to restrict the range of time according to date...for example to be able in the beginning before adding the new patient,to say that in august 30 of 2014 the range of time for appointments is from 9 to 10.So when the new patient is added on that date ,to book only between this range every ten minutes eg 9:10,then 9:20 and so on until 10.
I am really stuck and been searching the last week for a solution ,so any ideas on the implementation would be appreciated.
Thank you in advance..If you need some of my code let me know.
If you want to restrict the input data, you have to use the DataGridView's CellValidating event. There you can check wether the input is ok or not. If it's not ok, you can set the ErrorText field of the edited row, where you can explain to the user what's wrong with his input.
Have a look at this HowTo from the MSDN.

I require people to enter data into columns A to AI. For each row (which represents a client) I would like to create in row AJ the date/timestamp somebody changed entries in A to AI (it does not matter if something has been added or deleted, I would just like to know when somebody last looked at client data and updated/changed something). Is that possible to program with a formula or VBA?
Many thanks.

In my win form application I have used 'Advanced DataGridView'. For filter string columns it is working good but when i filter Datetime column the grid view becomes empty.
When i did debug it, i came to known that it is getting only dates and not dateTime from the column i.e
([Date_Time] IN ('11/04/2017', '12/04/2017', '13/04/2017'))
and this is the reason why my grid view become empty because there is no row with only date.
here is my code for 'Change filterString' event
Me.crossMatchBindingSource.Filter = dgvCrossMatchDetails.FilterString
So, my question is how can i include time in the filter.
I believe you are trying to bind a grid view to a data source, which uses SQL to extract data from the databases. I believe you can just amend your SQL as follows:
([Date_Time] between ('11/04/2017' and '14/04/2017'))
This should cater for times as well as dates.
You should just go to DataGridView properties and set "DateWithTime" to "True".
Then you are able to filter by Date and Time now.
Please correct me if i m wrong. whoever created AdvancedDataGrid, the code he/she wrote to filter can only filter the date and not the datetime. So i should split my datetime in two columns then i will be able to filter my dates. Actually i have done it and it is working perfectly but time column shows every record separately like text in the filter and not making grope of hours and minutes as excel does.
I have inherited an excel spreadsheet of ~7000 jobs that I want to turn into a database. I am trying to write a new job entry form. One of the fields is a job ID that is the (YY) year followed by a three digit sequential number, eg 16001,16002... Clearly this will need to change with the year and for this reason using this as the primary key is unsuitable. It is highly unlikely there will be more than 999 jobs per year.
Could anybody explain how I can get the field in the form and subsequent table entry to update automatically with the next job ID? I can access the last entry value with Tools>SQL>SELECT... statement and even return that value + 1 but cannot figure out how to create a field in my form that can automatically display this value.
Thanks all

There are good examples (credit: user DACM) on using database forms in the OpenOffice community forum, see: [Example] Invoice Forms (without macros)
Have fun!
I am trying to create my own schedule control basically (very simple), where I want to use a datagridview to display the columns needed and I need the row headers to display specific times (ex. 7 a.m - 10 p.m : 7am,8am, 9am... 9pm, 10pm) in intervals for each hour. I am developing a windows form and I am using an Access database. Along with getting the header rows to display the specific times that I stated above, since this is suppose to act like a schedule viewer, I will need to somehow be able to link my "time" column in my access database to correspond and display within the correct time slot. Below is an example of how I want my datagridview to look..
This is being using to schedule appointments so it will be possible to have 2-3 data entries where the time would be 1:00 so I need the row Headers to span 2-4 rows but for each record in my databases that has a time of 1:00 or 1:30 I would need it to line up correctly with the 1:00 row header.
I do not have any code yet attempting to convert a datagridview into a schedule control because I am not sure if this can be done and I am not sure how to go about linking the database to the row headers. If it is possible for me to achieve this can anyone give me advice on a) How to create my row Headers so that the time in my "TIME" column will correspond? and b) How do I get the times to link between row header and database column? Would the linking between the times be something done in the code behind where I could give a range and then assign it to the appropriate row header?
I have a dataGridView object called dgvMonitor that will be used to display pending consultations that are required to be executed within a certain amount of time by a supervisor. The supervisor is given 24hours from the time he submitted an entry, into the program, to complete this task.
dgvMonitor is being filled with an SQL adaptor and once that is completed, I systematically add a new column (REMAINING_TIME) at index 0 or basically to the first column, in the DGV, after I fill the table.
Now, what I need to do is insert a timer, in each cell within column (REMAINING_TIME)
What I would like to do is use the date in column (DATE_SUBMITTED) which is located at index 12 or the 12th column, in the DGV, add 24hours to each date, in that column, and begin counting down. Once the counter is equal to 0, an event will be triggered.
I did some searching on here and all I could find was:
How to create multiple timer handler in vb.net
and
add computed remainingTime to each inserted row of a datagridview
but I couldn't figure out how to apply their scenarios to fit my condition.
I would really appreciate anyone's help. If you need more information to go off of, please let me know and I will edit my question.
Thanks.
