View 6 RepliesI have the following set of code for a Sub program. It's inserting a row into a MSAccess Database using data provided in the containing form. What I would like to do is grab the ID number of this added record so that it can be set for a property of a window that is invoked when successfully added. I tried looking this up but I get something about @@IDENTITY but it's using an entirely different way of connecting.

' TODO: Check the form for errors, or blank values.

View 7 RepliesI've created an exe that is a ticket management system for in-house debugging, etc... It uses the same database that is accessible via MSAccess. In order to create a seamless work environment, one of the supervisors wants employees to be able to see data from the tables the exe uses without actually opening the exe and looking up the record. That's no problem since it's all the same db, but they also want to be able to open that ticket with the click of a button...instead of opening the exe and doing the search themselves, they want to just *click* and have the appropriate ticket open in front of them. I have no clue where to even start to do this....

2) click on search button - all details of chemical appear in respective places
3) next, i would require a link label to be clicked on to bring me to the specified chemical file because each chemical has its own special file
Its like each time I search for chemical A, the link label will show chemical A's file upon clicking it.and if I were to search another chemical, chemical B,the link label will show chemical B's file upon clicking it. Problem: i'm figuring out how to connect my linklabel to open the specified chemical's file link which is stored in ms access.In my access table, I have a table with two columns;
1st column: All chemical Names
2nd Column: Contains all the links to the chemical files that i want to open in the task above.Code I have done so far which is left hanging coz, I don't know how to modify it,

In Visual Basic 2010, I would like to create a form that uses a datagrid view pulling rows from a temporary table made at run time. When the "Submit" button of that form is clicked, the rows from the temporary table will be copied into the regular table. (This is being done as there is no ID# available until AFTER the form is submitted. The ID# is needed because the rows made in the temporary, as well as the entire form, will be associated with THAT number.)
how can I dynamically create a temporary table in MSAccess OR how can I use a datagrid without associating it with a table?
i want to transfer data from datagridview to msaccess table...but there is something wrong in this code.. im not finding a way to do that

In vb2010 I am trying to create a small program, I have a textbox and a combobox.
The combobox items are dynamically loaded.
The msaccess database has 3 columns (excl id), groupname, realname, emailaddress.
When I select in the combobox an item, records who has the same name in the groupname column, should select all the email addresses (seperated by a ";") and put them into the textbox.
For example:
When selected Group1 in the combobox.
1: Group1, Rick, rick @ rick.com
2: Group2, David, david @ david.com
3: Group1, Louise, louise @ louise.com
In this case the emailaddresses of records 1 and 3 should be into the textbox:rick @ rick.com; louise @ louise.com
