When I work in one form, it will save this form name in History Menu, so that I can reopen this Form after that, we can choose the number of Forms saved in History Menu.

I have a small script that logs all of the website I visit and then displays them on a form. When I open the form the first time it displays all of the websites like it should. However, the second time I open it, it displays two of every website. The third time opening it, three of every website. I think that it is because the data doesn't get erased from the listbox when I close the form. Is there a way to clear the listbox when the form closes or do I need to find a new way to set it up?

The plan is to put the tool in a central location so that anyone can use it.I'd like to store, somewhere, the date of the last backup for each server. I was wondering if I could use an application settings (with Application scope) for this? Is this bad practice? If so, what's the best practice? XML? text file? registry?

View 2 RepliesI am trying to create a simple parent-child form in VB2010. I use a datagridview for each table/datasource and each is bound to the paretn/child table and each table grid fills correctly. What I want is the parent-child relation to enforce filling the child table with only rows that fulfill the current row on the parent. I have created a DataRelation in the form load, but it will not permit a relation between tables in 2 different datasets. If I attempt to place both tables in a single dataset and define the PK-FK relation in the SQL Serve,r I cannot create 2 separate datagrids from the same dataset.

[Code]...
I have a project that will need several forms with a similar structure - a Data Grid View control, a few buttons and some textboxes. They are not similar enough to use just one form and change things programatically so I would like to create a "template" and add several copies of it into my project. My first attempts have failed miserably, ending up with lots of "conflicts" and "duplicate items".
So, how should I save a form from my existing project in such a way that I can then load in multiple copies (giving them suitably different names) without having name conflicts?

View 5 RepliesI have another question (and anticipate that I will have about two more before I'm done with my class project). Here is my issue (and I'll copy and paste my code for clarification). I need to link up the control from the form on either side of the current form that I'm working on so that if I click on the buttons that I'm titling previous and next that I can click on the proper button and either go directly to the previous form or the next form. I was successful in doing this for two earlier forms on this project (with some direction from a couple of helpful people on this forum before), but for some reason, no matter what I details I use the controls do not connect to the previous and next forms.
