I have struggled to find a way to make this work. I have a listbox that has 5 items. These items are lets say Company Name, Address, User Name, Phone, Fax. On the form I also have the same labels with richtextboxes under each of the above names.What I am looking to do is have each listbox item equal the text that is related to each textbox. Then write to file from the listbox.The file created should be the text from the related textboxes.The goal is to allow the user to re-arrange the items in the listbox via drag and drop (which I think I have figured out) and write a new order of the file[code]
I have a database called BDEP.accdb already connected to a program in vb.net is ok, but I have a problem.I have a list box with the name of the fields in the Customers table but I can not find the code to search this list information starting at a textbox.
i want to search item A (from a list of X items) in list B but i want to get the item not found example Search ITEM A in LIST B if not found then return a print....if found continue with ITEM B..and so on.
Hi, I'm working on a program that reads text entered into a textbox and creates a list of items by separating entries by commas. Everything is working fine, except, because I am using an array to store the items in the list, I have a limited number of entries. This is only a problem because, as it is written currently, each comma counts as an individual entry. Therefore, users can enter ",,," for example, and it would use up 3 places in the array.
I'm looking for a way to check to make sure there is text after the comma before adding an entry. I've attempted to use the .substring command to check the character after, which works until it gets to the last character. Because there is no character after that, it will give an error.
Here is my code for extra clarity:
Public Class frmMain Dim intCounter As Integer 'Stores the # of commas in the string Dim Messages(49) As MessageProperties
I know this must be more simple than i'm making it out to be, but it's not working for me.I have a listbox with items that are set up in a specific order and need to be kept in that order when going into the text box line by line.
I'm trying to add multiple items to a list box from a database but I'm having a few problems getting it to work. Below is the code i have so far but for some reason it will only add the last field in the database to the listbox and not the remaining 12.
I have squiz my mind out for this but no luck I have a Windows Form with a list box that gets data from a MS access Database table(table1).The table fields are NAME,SURNAME,AREA.In the list box i see the recors of AREA(for example:NY,Chicago,L,...).I want to do this,when a user selects a item from the listview and click OK Button to open a new form with the selected records(with all the table fields).How can i do this
I have a listview (details) with owner draw set to true (so i could make rows alternate in color, looks cooler) which basically contains items and subitems whose texts reflect status info that updates constantly the problem is, sometimes (if the task runs quickly) the status changes really quickly, and as a result, listview items "flicker" for a millisecond no error, no real problem, its just really annoying and makes the program look less professional.
Is there a way to make the listview not flicker? Or maybe there is a way to make it so that the listview doesn't process too many drawsubitem calls during the same time interval? or maybe there is some customized list view out there that does the trick better?
NOTE: i tried with owner draw set to false. it flickers less, but still flickers. same problem :S Also NOTE: i am not making cross-thread calls. i have 50 items in the listview and 4 colums, mainly the last 2 subitems change.
I've searched on the Internet and I can't find a solution to this simple problem. I've also looked on Microsoft's MUCH improved MSDN site and haven't found a solution, so here it goes. I'm trying to remove an entry from a list of class and it doesn't get removed. Here's a sample of the code I'm trying: (I renamed the class and variable names to make it a simple example)
Dim lstClass As New List(Of TheClass) Dim mClass As TheClass I tried this first mClass.filename = "The Entry to Delete" lstClass.Remove(mClass)
I have used list views for a project. I have used sum items on the items. The sub items are prices of products. I will need to use these sub items to come up with a total.Also, i have used to listviews, for a smoother look and feel. You click the product which then is removed from the list view and added to the second one. Would this also "move" the sub item across to the other list view?
Im planing to make a little radio application for my own use,I want a Combobox with list of items and a URLs binded to them.for example i got 3 items in the combobox:
Radio1 Radio2 Radio3
I want it to be like when im choosing the "Radio1" and press my Play button ( AxWindowsMediaPlayer2.Ctlcontrols.play() ), the 1.1.1.1/Radio1.asx will open.
on page load i have a listbox which gets populated with the subfolders of a folder, im trying to have it so a progress bar fills as each item is added but im not having any luck with remembering how to do this And googles not been to helpfull.Heres my code so far:
vb Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load ProgressBar2.Maximum = ListBox1.Items.Count ProgressBar2.Minimum = 0 ProgressBar2.Value = 0
I have problem on my project on vb.net I'm using visual studio 2008. May I know how to do to show all my sales everyday. I have sale almost 5 items every day I want to have list for this. I'm new on vB.net..
im making a small Keyboard macro, I have a multilined textbox and when a user pushes start
[Code]....
but its sending all of the textbox items at once, can I break it up using I dont know indexof? and send it one by one if so how do I use indexof correctly?
In my project when someone logs in I refresh the overhead and side menus. My overhead menu is an extended menustrip component that I have made. I am able to clear the menu, reload it dynamically but I am not able to add/insert the open windows which are managed by the mdiwindowlistitem property. These are the items named "1 - form name " "2 - form name" etc.
I have been able to copy the whole dropdown list, and with some very hacky loop work I can take out everything but the items related to the forms. But when I add them back in, they are not on my list. The related forms are still open and if you click the maximize button to shrink a open child window, and then re-maximize that same window...the items magically show up in the list.
This ManageMenus sub is called during a login change. If you breakpoint on "openwindowslist" after it is returned with data, it has the proper entries and nothing extra. It just seems that the for/each add loop does not actually add the items. Or, if it does add them, I can't see them.
Tried both insert and add functions, same results both ways.
CODE:
In my xmlMenuStrip component this is the function that removes everything but what follows the seperator. It returns them in a list.
I need to load a large txt file that is in a fixed width format. There are over 45K lines, so speed is important.I need to load one of the fields into a dropdown box and have another field (label) display the text of another field in the related line.I could import the file to an access db if needed, but would rather not as i also want the txt file to update from a link on a regular bases. So having it in a DB would be more work to process that part.[code]
I have a table being imported into my VB application that has 3 columns. I have written code to import the table, and have written code to display on the first column (country) in a list view.What I want to do now is have the user select / highlight an item in the list view, and have the third column (currency) related to that selected country appear in a text box when a button is clicked.Here's the code I've written that successfully imports the data and displays the first column:
code Private Sub frmCountry_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
I'm looping all the properties in an object via reflection:
For Each p As PropertyInfo In values.[GetType]().GetProperties() If p.CanRead Then 'Do stuff End If Next
how to determine whether the property in question is a generic List(Of T)? If it is I need to loop the list itself.
I've experimented with GetType and TypeOf but have not managed to get anything working.
To clarify, I want to keep this generic. I do not want to specify the type of T, I need to loop the list items and call the ToString method on each item. T could be one of a number of different types (application specific reference types). Is it possible to do this without specifying types?
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)
Public Class frmCheckOut Dim i As Integer Dim cleaning As String = "Cleaning Inspection" Dim damage As String = "Damage Repaired"
Another program I am working on for fun, I am basically shuffling a list inside a listbox, what I want to do is delete the rest but not sure how to go through with that. At the moment I have this: [code] Just contains the code, declarations outside weren't included.So anyway, once clicked, it will call on the function to basically shuffle in a for loop, I was wondering if I should (or how should) create another function and call it in the click button or have just a loop in the click button so it deletes half the list. What I am doing is I have 20 list of items, I want the program to shuffle the items and then deleting the lower 10, meaning, if I had 10 items and wanted 5 top, I'd want: 0, 1, 2, 3, 4 and deleting 5, 6, 7, 8, 9.
I am attempting to read the results from a SQL query into a List(Of) and I can see the List.count while adding items to the List increments, however in another part of my code when I am attempting to read the List the List.Count returns 0. My List is as follows:
I am making a program that when you click a checkbox it will add a corresponding list of items to a textbox. The only problem is that I have lists that are about 20-30 lines long, and all I know how to do is items.add "item" I was wondering if any one knew a way that I could add a long list without out items.add.
Here is a sample
Private Sub CheckBoxes_CheckedChanged() Handles CheckBox3.CheckedChanged, _ CheckBox2.CheckedChanged, _ CheckBox1.CheckedChanged
I have an error panel that is subbed in to a page if an error goes wrong to gracefully handle and display errors.Currently, I am just appending the error messages to a string and pushing that to a label. If you have multiple errors, this gets messy.I'd like to push each error to a list item in a bulleted, unordered list.How can I dynamically generate, from a vb codebehind file, new list items inside of an undordered list element?
I have two generic lists, named ListA and ListB. Both ListA and ListB could potentially have duplicate items. What I would like to do is use LINQ to grab the items in ListB that are not in ListA, but I'm unsure how to do so.
That was probably bad title, but I'll illustrate what I'm trying to do. I have a method in a class that I need to call several times. The method returns a List(Of String). I'm just grabbing some information from a database.
VB.NET Public Function GetTestList() As List(Of String) Dim int As Integer = 0
I am creating a program in Visual Basic 2008 and I would like it so when I check a check box, the word that corresponds with the check box (in the code) will show up in the text box. So if i had one check box that said, Hello. Whenever that check box was clicked the word, Hello, would show up in the Text box. And then if I checked another check box, Bye, the word Bye would show up right below Hello. So it would look something like this.
Hello Bye
But whenever I unchecked the check for hello, the word hello would go away and Bye would move to the top of the text box.Here is the code that I have so far. I can make the words appear in the text box but not at the same time in the list.
Public Class Form1 Private Sub CheckBox1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged If CheckBox1.Checked = True Then
I have a List(Of MyObj), and I want to iterate through that list and compare each element to all other elements in the same list, excluding (if possible) the same element. I have a solution that works, but it's slow and uses double For loops. It may possibly have also summoned Cthulhu from his sleep. This below is a sanitized version of what I have:
Dim MyList As New List(Of MyObj)({Obj1, Obj2, Obj3, Obj4, Obj5, Obj6}) If MyList.Count > 0 Then For i = 0 To (MyList.Count - 1) Step 1
