I'm working with a vb.net project that was converted to vb.net from vb6. One form has a groupbox array. So I see one frame, but there are several others behind it that I can only see if I drag the contents of the current frame to the side. Is there any way to view all of the frames at one time? I don't know how to edit or add something new to this form.
View 4 RepliesOn VB.NET 2005 and 2008, if you were debugging you could roll over the variable you set as an array and a little "+" would pop up next to the array variable and you could click it and see all of the data loaded into the array.

View 2 RepliesHere using VB .Net 2008. I seem to be having trouble getting group boxes to appear when I click a radio button.
For example:
CODE:
This indeed brings up the first radio button however I have other groupboxes underneath which with the same code will not appear when the radio button is checked.
Eg:

The second groupbox does not appear and is directly behind the first groupbox. The Top code doesn't seem to be working either.

I would like to integrate a day or week view to a time recording application. This would enable users to add preset activities to their calendar and edit those actiivities to reflect the time they've spent on them.A perfect example would be the excellent work from April16 here . Unfortunately, my company will not pay the price April16 is asking for this component. No need to post comments on that...The time recording application already exists but was recording activities in a different manner, which enabled me to use DataGridView with activities and percentage of time spent on them. I would like to make it more user-firendly.

I'm using VB 2010 Express. I'd like to ask about tree nodes - in my application, the user can change the nodes and add more. When I leave the application, I would like to return and for the new nodes to still be there. I've tried My.Settings, but I've decided there must be another way to do it in a file. For each node, I need to save the key and text, and reload it next time.
View 4 RepliesI have a table of 51 data points all numbers between 0 and 8000, i have stored the data in an array of ushors's, and on my form i have 10 numerical text boxes, So that the user can change the values in the table every 5th value. Using the value changed event the program then re-calculates the values in-between.
What i would like to do is show the table in a data gridview and allow the user to change the values in the array using the datagrid view, i know how to create a table but not how to link the table, so that it can change the values contained in the array.
Below is the code i am using to create the table:-

The problem (and confusion) that I have is - what is the difference, and which should I turn to?Am I right in assuming that VB.NET 2003 and VB 2005 are different, or am I ok to learn .NET 2003 until the 2005 version comes out?I know this might seem like a dumb question, but I want to move onwards and upwards and am a little confused, as I dont want to concentrate on 2003 if I'm going to be learning an outdated language in the next couple of years.
View 8 RepliesI'm working with a DataGridView. The DataSource for the DataGridView is set to a DataTable that I've populated with the results of a SQL query.
Then, I add an extra column to the DataGridView, a DataGridViewCheckBoxColumn. This allows the user to select a number of records in the datatable in order to save out selected files, represented by the rows of the datatable/DataGridView.
I have buttons that will programmatically check/uncheck all of these CheckBoxes, as there are frequently several hundred rows in the DataGridView. The user can also check/uncheck any number manually.[CODE..]
