View 1 RepliesWhen writing to an Access file with one of the fields indexed (NO dupes allowed), I am getting the following message in the Immediate Window "A first chance exception of type 'System.Data.OleDb.OleDbException' occurred in System.Data.dll", when I enter a dupe.
I have put in a TRY, CATCH to catch the error and display a msgbox with the error. Is this message in the IMMEDIATE WINDOW just a warning message (generated by access), or is there something wrong with my actual program? My program does not actually crash, it seems to be working great.
I am creating a programme in which the user searches a file by typing into a textbox. if the search terms match anything in the file, it will be displayed in the list box. I understand this may be unclear so i will include an example:If the user enters "Oliver" into the textbox, the programme will search the file for any records that include "Oliver".The records are stored in structures:[code]The user will then click the desired record (several may appear)how would i get the integer and perform simple addition and subtractions on it?

First my prog scan a specific path "C:music" which contain Mp3. Then it takes the MD5# of all mp3 and put it in a listbox1. Also on the formload it does open a ".txt" which also contain MD5# that goes into listbox2.Now this is what i am looking to have :When i click my button it compare each line of my listbox1 to listbox2. If , for exemple , the first line of listbox1 is already in the listbox2 then it delete the first line of listbox1 (listbox1.items.removeat(0)). And Do until listbox1.items.count = "0".

this is the same code i used for my last app to populate a list box?
I have a program I'm trying to put together to allow my employees to submit shift reports. I'm doing this simply to make my life a little easier as this way, they will all be formatted the same. Instead of spending a large chunk of my afternoon thumbing through a bunch of differently formatted reports.
One feature that I need to figure out requires that one listbox can see what another is doing. Here, let me try to explain..
I have one list box that keeps track of EVERY action the employee does on a customers account. (cancel, upgrade, downgrade) and then a hidden listbox that JUST tracks "cancel" actions..one for "upgrade" actions and one for "downgrade" actions.
The reason behind that is that in the shift report, the all need to be listed separately. This way, I can just add each list to it's own array and list them where I need to.
The problem I've run into... If an employee handles an "upgrade" action at the beginning of the day..and then later on the upgrade is canceled, I can easily remove it from the main listbox that shows everything, however, I can't figure out how to find it in it's own listbox. The "Upgrade" box.

So unfortunately, on the shift report, it's still there even though it's gone in the program as far as the employee can see.The item in the main listbox doesn't have the same index as the item in each individual list boxes so I can't just tell it to remove the item at the same index..

I have built a web browser using vb.net and I want the user to use this only, that is I would like to restrict user form using any other browsers.So the question is, how to kill a process (IE) the moment user opens it. I am able to get all the processes and able to kill the current process. But the current process is always my app.

I've got my first ever program and it's working. Having tested it a bit it would be helpful for the user to be able to copy the results printed in a listbox into an email or text doc. Just somewhere where they can make a note of it really.Is there something I need to do to enable it? All the google results I found were referring more to doing this in code. I literally want to be able to support Ctrl+A, the Ctrl+C straight out of the program to wherever the user wants.
View 4 RepliesI am starting to feel completely dumb when it comes to VB.Net coding. I am using Visual Studio 2010 and am trying to compare the numbers in 2 listboxes. If an item from list A matches an item from list B, I want it to add that item to List C. Once it has added the item to List C, remove those searched items from list A & B. Continue until it runs out of numbers to check.
If you are wondering what I am trying to do, I want to make a Common Factor list. I already have the Factoring list done, but got stuck here.

I have this exercise which says the following: Create a form with 2 listBoxes. Add a number of items to one listBox. Create a button that when clicked removes the selected item in the first list and adds it to the second list... Also How can i create a Messagebox that will display error when nothing is selected
I wrote this code:
CODE:
I have a datagridview (parent) and a (well, several) listboxes that I am trying to create a relation with.Datagrid has master records which contain ID fields to lookup tables. The lookup tables are populated into listboxes.I have 1 dataset which contains tables for my datagridview(s) and my listboxes.I need to create the relations so that when they click on a row in the grid, it shows the corrisponding item in the listboxes as well.Problem is, a lot of the ID's in the parent table are empty... so when I try to create the relation, it blows up.
Code: "This constraint cannot be enabled as not all values have corresponding parent values." I'm doing like like so
Code:
lo_relation = New DataRelation("RelationName",DataGridTableIDColumn, ListboxTableIDColumn)
I tried to reverse it, naming the ListboxTableColumn as the parent. That allows the relation to build, but I can't set the Listboxes .ValueMember to that...I'm kind of stumped... as it needs to be a two way relationship.
1) When the parent record (datagridview) changes, it changes the value in the listbox
2) When the Listbox changes, it changes the "value" in the parent datatable so it can be updated.
Would I resolve my issue if I populated the parent with a "default" ID in each field (say 0)... if the database value is null? And furthermore, populate each lookup table with a "blank" default value as well? i.e. First record is ID = 0, Desc = ''?
I've seen the code on this site to setup a drag-and-drop between 2 listboxes (and that works perfectly for me), but I have a need to be able to move items between up to 12 listboxes. For example, I move an item from listbox1 to listbox2; at some point in the future, I need to be able to move that same item from listbox2 to listbox3, then at another point in time from listbox3 back to listbox1, etc. When I make these moves, I need the item to be removed from its previous location. I've attempted to modify the 2-listbox code to include, on my test form, a third listbox, but that code copies to the third listbox, and when I attempt to move the item from the third listbox to the second, it, too, only copies and does not remove the item from listbox3.
View 1 RepliesI have almost completed coding moving entries between listboxes. My only hangup is: when I trigger the dragdrop event I get the target listbox x,y coordinates. I need a way to convert these coordinates to an entry number so that I can insert the source entry in the proper place. Any one have a solution?
View 2 RepliesI want to create a program that will let the user input a number and it will go to listbox1. Then listbox2 and 3 will do some algorithms that i made. The only problem that i'm encountering is the average of listbox3.

what I want to do is make it so when i select the first item in Listbox1 it will also select the first item in listbox2 and if i select the second one it selects the second one on listbox2 as well. Is there a way to do this? i honestly have no clue and i know my code is wrong cus i do not know how to select the item # on listboxes but this is what i have:[code]

I have four list boxes, side by side. I've got a huge list of files that the program scans through and if (file insides) = (this) then; else if and etc. I know that part is working. The problem is actually the list boxes themselves. The reason I know this is:
I have four listboxes side by side, only the first one shows data, but if I delete the first one from the form, only the second will show data, if I delete first and second, the third one displays data, and if I delete the first three, the last one shows data. The problem is they wont display data at the same time. I was talking with someone else and they said I needed to change the IDs and I should see that option somewhere near the "Name" section. I use Visual Studio 2010... I don't see any IDs option to change. on how I can change this ID or maybe something I have to do to get these listboxes working?
How do I parse this and add the names and IDs in Listboxes ?

"data": [
{
"name": "Some Name1",[code].....
