visualize 2-dimensional array visual basic - vb.net

I started making a very simple application where a list of names is shown in a checked-listbox.
Now I would like to add a date as a second column value. This means i have two use a two-dimensional array.
What containers could be suitable to visualize a 2 dim-array on a form?
I was thinking as an alternative I could keep it one dimensional and use a delimiter. Would there then be a method to format this date on the extreme right side of a listbox? I guess I would have to extract the date part, but I don't see how i could position it in a listbox.
I am working with VS2010 and using a windows forms project. I have no experience in VB (but some in c++), and no experience with GUI's at all.
Thanks in advance

Either the ListView in details/report mode or the DataGrid would be good. Personally I prefer the ListView when possible.

How to use option buttons to change a value in a Word 2016 table

I am attempting to create a form that uses option buttons to assign a score, which would later be totaled for evaluation purposes. (I am using Word 2016 on Windows 10.)
Here is a pic of a portion of the proposed form, with 5 columns:Proposed Form
Here is a picture of the code I have attempted to use, which worked just exactly as I wanted it to "in EXCEL." Due to needs in other parts of the form, however we will be using Word, not Excel.Code Pic
Since we've decided to use Word, due to other features that Excel lacks, what code should I be using that would place a point value in the "Points" column? (I am assuming e2 to be the address of the 2nd row, 5th column?). I have spent 2 days so far trying to understand how to make this work. I know it can be done, but I lack the specific coding knowledge to make it happen. Thanks in advance for your help!
You appear to be using both formfields and ActiveX controls. It would be far simpler to use just formfields and, instead of having radio buttons, a simple dropdown for each item. That way, you don't need all those separate columns and the results could be tallied from the dropdown selections without the need for VBA.

VB.NET - How to Create Information Box

I'm creating a form that will display a long list of properties and their associated value. I'd like to display them in a sort of table-like control. Something with heading values at the top and a list of organized data underneath it. Something like these:
I realize those 2 examples aren't exactly the same but I'm flexible on what I produce as long as it gives a similar effect. My question is, how do I create a list like that? Is there a control in the Visual Studio toolbox that will produce this effect?
I'm sure there's something similar that easy to find but I can't figure out what to call that control so my searches haven't turned up anything useful.
Any help would be greatly appreciated. Thanks!
A combination of ListView and TabControl controls could be used to emulate what you're showing above. See the links for ListView and TabControl to help you get started.
Yes, there are windows form controls that provides this functionality.
For the tabbed windows use the TabControl:
For the different lists use a ListView control in the mode Details - which means a list with columns:
For the second feature, the ListView control has the Group features:
In order to group items togheter set the group for the chosen item(s):
All of this can be of course done programatically. There are good tutorials on MSDN and Channel9.

ReportViewer: two text colors, one cell

Is it possible to have 2 areas of text in one cell such that each can have a different color? You can do this in crystal reports but I cannot see a way to do this in ReportViewer. What it is doing is essentially highlighting an important text fragment if it appears in a cell description to draw the users attention. I am fairly new to reportviewer so it for now I am assuming it's my lack of knowledge that is making this difficult. I am using VS2010.
Thanks.
Turns out VicarlnATutu wasn't quite right.
You can do this, but only if you are using VS2010 (which I am) because it includes the new SSRS rendering engine for SQL-Server 2008. This allows you to put some basic HTML into a field and have multiple formats in one cell. For more info see below:

One thing that tripped me up is what they call a 'placeholder' in the MS documentation is the little bit of text inside the textbox control that shows up by default. You can select two different things on the control in VS2010. One is the textbox itself. Right clicking on the textbox gives you 'text box properties'. The other thing you can select is the default text INSIDE the textbox. Right clicking on this 'placeholder' text gives you a different context menu where you can select 'placeholder properties'. This is where you can change the cell to accept HTML.
No, unfortunately not. I don't know if there are custom controls out there for ReportViewer, but the built-in TextBox only supports setting color (be it Foreground or Background) for the entire thing.
ah, good to know. kind of a unintuitive way to tell a TextBox to display HTML, but nice to know that you can!

Best way to select from a list - aren't the two listboxes getting a little old?

How many times have we seen this type of selector:
List Box Selector http://geekswithblogs.net/images/geekswithblogs_net/dotNETvinz/MoveItemsListBox.jpg
I was just about to start creating this in a WinForms app, when I thought that others may have some ideas for doing this better. We need it to sort - so the right hand list will need up/down buttons. But this seems so old school. I love devexpress components, and was thinking of asking them if they would consider adding a component that handles this functionality with a slick UI.
I am thinking that a graphical representation of the objects, and a graphical representation of the listboxes - that would be a more intuitive way to move items around.
Has anyone seen an open source project like this?
If a CheckListBox won't suffice (and it usually will), then the "modern" approach would be to use a ListView or similar component with a "Transfer" column. Render the button inline in that column, one for each row, so that it only takes one click to move an item from one to the other.
You see this everywhere in Vista, usually with hyperlinks as opposed to buttons. Instead of clicking on an item and then choosing an action, you click the action at the item level.
I wouldn't go overboard with slickness as it can impair functionality, but the dual-listbox screen is definitely old-school.
Also, if there's a very large amount of data to manage, it helps to provide a progressive search at the bottom of one or both lists.
I have done this type of selection using (essentially) a single CheckListBox that displays each item as an image. Part of the image looks like a LED, which is on (bright) if the item is selected or off (dark) if it is not selected.
This works well if you have a reasonable amount of data to select from, and also works well in a multi-column format if you can predict that the options will have reasonably similar lengths.
Allow users to drag items in/out of list 2, and also drag to reorder in list2.
(All items dragged out of list2, and dropped anywhere outside the list, get put back into list 1, in their correct place in the list by alphabetical or natural order.)
You can merge the two list boxes into one with the help of groups (LVGF_GROUPID flag): one group for selected and one for not selected.
You can also implement group membership changes with drag-drop between them. This way single drag-drop can move an item into the other group at the appropriate position, saving most/all of the other buttons.
Additionaly the bottom of each group can have one pseudo item with help text (i.e. "Drag items here to...") that is visible only when relevant.

Porting a VB6 application with msflexgrid to vb.Net

I am porting a vb6 application to VB.net. One of the key forms has a large msflexgrid on it - about a 1000 columns and 50 rows. It has 2 header rows - the first header row has merged cells to form a main header and the second row has sub headings. There is no requirement for any data entry and it's unbound. The code does the work in deciding what to display (if anything) in each cell. It is solely used to display data in the form of a character and a coloured background and to display a tooltip text with more information when you mouse over it. Works beautifully in vb6.
I'm trying to decide whether to:
a) use the vb6 msflexgrid in the .net version
b) use the datagridview - which at a first glance seems to have a problem merging the cells on the header row
c) build my own custom control to do the job
Has anyone got any suggestions for the best approach?
I would suggest using the DataGridView, primarily because using COM objects in .NET is a pain. There is a MSDN page for exactly what you want to do here, and some additional discussion here.
