I can get this form to output everuthing but multiple items selected by the user. I am a student and I have been working on this problem for a long time with no luck.
Private Sub btnAddBooks_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAddBooks.Click

wondering if someone can help me some small issues I am having with building my first project.
1.I have comboboxes that allow users to enter their own choices in and then their choices are displayed into the gridview.
the problem I am having is this is allowing me to duplicate choices. for example:when I run debug to try my boxes, I can type in Johnathan into the combobox as many times as I want to and it adds is to the combobox list..so now I got 10 johnathans in my combo box.and then to make things worse, when I hit the button I made to send choices to display..it causes duplicated choices to show up in the display.What I figure is that it is easier for me to just prevent duplicates in combobox.
2.Lets say on one of 10 comboboxes I got...lets say someone skips the box and doesnt make a choice...my grid will then display the last choice made.. (man o man)for example:John chose in his boxes and is displayed on gridview: Combobox1 (john) Combo2 (5:00 PM) combo3 (waiting)now lets say I come up to the computer and in Combobox1(Dcurvez) Combo2( i skipped and didnt enter a choice) and Combobox3(In Progess)
The display will put Dcurvez....5:00 PM.....In Progress because I didnt make a choice in the time combobox..it put in the last choice (Johns) as 5:00 PM Can someone in very simple terms tell me how to fix this problem?? I am using visual studio 2008 and vb/vb.net as language this is not a webpage, btw. it is for in shop computer just.

I have a datagridview binded to a list of objects... I have a column named Selected containing a checkbox. When these checkboxes are checked and a button is clicked, I want those particular rows to be removed. I initially set it out to iterate through the grid's rows and RemoveAt(SelectedRowIndex) but of course when it removes an object from the List of objects at the selected row (IE Row 1, 4 and 6), the list indexes change and it fails to work properly when it goes to remove the next row since Row 4 is now row 3 in the list...? What is the best way to do this?

I'm making a combobox on a form. I want the combobox to have a list of choices from a table in a db. The two columns are a String and a Date. I want the date column to only show the year. I'm hoping I have the code right as it is above, but I'm not positive I've done the whole date thing right.

I'm new to Visual basic (which will be obvious from my question) and am writing program that does various calculations, then displays the results in a list box. the results, however, are all concatenated, end don't each appear on a new line. I tried adding a carriage return/line feed at the end buit the compiler rejected it.
I can't find any examples of creating a list box, and adding multiple entries (one for each time a loop is performed), nor of how to use columns to make the resulting display cosmetically pleasing.

This program is supposed to allow the user to check items in a checked list box. If the item is checked, it goes into the Completed List Box on the right. The program then adds the unchecked items to the Pending list box on the left. I keep getting placement values (e.g. O,1,2) instead of the strings (e.g. "Key Returned") in the list box results (see photo attached)

I have 12 Boolean values in an array. Each of these values represent a CheckBox in my application. I want my program to output a string, based on each value not selected. Each of these values will have a predetermined string that is different from the CheckBox's caption and will be joined to create a final string. I want to generate all the possible combinations for when there are 1, 2, 3, 4 and so on up to 12 of these options at once. I can better explain my problem through the repetitiveness of the code below.

I am trying to create a deployment project for a solution of many projects and two start-up projects. I understand that there are 2 primary outputs in this case. The solution will not work/make sense if either of the two outputs is not running.
At the moment, I have created a set-up project with the multiple outputs, but then I will have to open the outputs individually for them to work. I am wondering if there is a way to create a desktop icon that targets both outputs simultaenoulsy.

I'm having trouble lining up data from a file with their respectable columns in a list box. I am using print zones to space out data evenly, but when i run the program the output is still messy. So I need lining up columns properly together. As of now, the first 2 list box items line up with each other perfectly, the data i am looping through to add to list box is not lining up correctly. I have changed my zones several times, but still no luck.
A chunk of my code (some) :
Dim fmtstr1 As String = "{0,-5} {1,20} {2,7} {3,7} {4,7} {5,7} {6,7} {7,8} {8,12}"
Dim fmtstr2 As String = "{0,-5} {1,20} {2,7} {3,7} {4,7} {5,7} {6,7} {7,8} {8,12}"
Dim fmtstr3 As String = "{0,-5} {1,10} {2,7} {3,7} {4,7} {5,7} {6,7} {7,8} {8,12}"

My app outputs to printer and after much effort (and assistance from this forum) I got the print output formated to an acceptable output, except when certain user choices make for a multi-page document. The document prints one page and then cuts off. We formatted the output using a defined rectangle (the code for which I do not fully understand) to format the page. Can experienced users give me some help on getting a multi page output?

i am trying to create a list of list in that i would like to work on multiple accounts at the same time. lets say i have 5 accounts. every account has a seperate name. each account has a few fields. so i though of having a list of bookkeeping (with 5 accounts) and a list of accounts (with expense, income, tax, status, etc as fields). [code] and if the idea of using list of list works how do i loop through both lists.
