.net - Drop-Down Image List In Winforms?

Aug 17, 2009

I'm trying to find a dropdown-style list for images I can use in a program of mine. It's fairly simple, just needs to display a few images in a grid with tooltips for each one, and I need to be able to get whichever one was last picked. For example,[URL] without the tab bar in it. Unfortunately my monetary budget is zero which means I can't purchase any controls?

WinForms Version Drop Down List

Dec 29, 2011

what is the Windows Form version of a Drop Down List? I would think a Combo Box, but that only seems to have a Text for the Items, not Text/Value (with Value being my primary key for the table I'm populating it from).

Apr 5, 2011

Is it possible to reorder the elements of a drop down list (combobox) via drag and drop?For example, when the list is dropped down, I want the user to be able to drag the items up or down to reorder them. I tried this (and some google searching) but I'm wondering if its just not possible:

Private Sub cmbClassLists_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles cmbClassLists.MouseDown
If cmbClassLists.DroppedDown And Not cmbClassLists.SelectedIndex = -1 Then

Winforms - Uploading Multiple Files By Drag And Drop To FTP Server Using .net?

Jul 30, 2011

I am trying to add multiple files to FTP server by dragging and dropping and I am able to do that using try catch block and if we give the ftp settings correctly it takes 1 sec to upload them but when we give wrong details it hangs up and dosen't give me any error message though If I give an exceptional message.

Now I am getting error message as well as success message for every file I add.I do not want that to be happen.where should I give messages for success and failure so that it should take few seconds for uploading and if not should give me a message immediately.

Here is my code:

Private Sub uploadFile(ByVal FTPAddress As String, ByVal filePath As String, ByVal username As String, ByVal password As String) 'Create FTP request

For i As Integer = 0 to images.Count - 1
images(i).Dispose()

SQL Data Access: VB2008 / VB2010 - WinForms - Create A Datasourse And Drag / Drop Fields Or Tables On A Form To Create A Grid

Oct 22, 2010

I have used VB (versions 2 - 6) through many years; however, I am crash-course training myself into the VB2008 / VB2010 world kicking a screaming. I would like suggestions as to what SQL database access method should I focus more on in my learning process without making me feel that I'm a million years behind. I know I have WinForms where I can create a datasourse and drag / drop fields or tables on a form to create a grid (not really what I'm looking for).

My trouble isn't so much designing the form but in how I access the database. Theres XML, LINQ to SQL, ADO.NET, and many other methods. Not only do I need to grasp these methods quickly but I also need to know what type of projects I should create. What I mean is...I was thinking that I would design a WinForm app; however, I see that there are WPF apps and others to chose from. This is getting deep. I know it depends on the project that I'm working on. My plans are to write an app based off of either an SQL Express 2008 or SQL Server 2008 database. This first app will be standalone for now but may later become multi-user. I know I'm far behind on my learning curve coming from VB6. I have read a bit on VB2005 / 2008 / 2010. I own
both VB2008 and VB2010. I use VB2008 at work. I know ADO.NET is still alive but by what I read online, it's a dying method and is only kept for backward compatibility. XML and LINQ to SQL and other methods are all pretty new to me.

Winforms - List Data In Ms Sql?

Mar 10, 2010

Below is the code that I'm using in ms access to list the data according to what is selected in combobox and what is input in textbox.

My problem is there no commandbuilder in ms sql like in ms access, because it fails when I try:

Here is the code:

''#list school
If ComboBox1.SelectedItem = "School" Then
Dim connectionString As String = "Data Source=SENBONZAKURASQLEXPRESS;Initial Catalog=testing;User ID=SenbonZakuraRew; Trusted_Connection=True;"

[Code].....

-There is no such thing as commandbuilder in the options that will appear. Do you know of any alternative of commandbuilder in ms sql?

Finding Value In Drop Down List?

May 31, 2012

I am trying to compare a calculated date with a value in a dropdown list. The value is a date.toString.This is what I have so far:

Dim sched = scheduleDateVal.toString("d"
If Holidays.Items.Contains(New ListItem(sched.ToString("d"))) Then
ScheduleDate.Text = scheduleDateVal.AddDays(1).toString("d")
End If

Holidays is a dropdown list bound to a database so that I can add a day to a scheduledate if it happens to fall on a holiday. This works if I add a string value to sched rather than converting scheduledateval to a string.

Make Drop Down List?

Jan 13, 2010

I'm creating a simulation programe. In one sheet I have a group of cells (AngleConf) that have a drop down list. I would like to make some operations when I change the value of one of these cells. It always works when I insert the new value manually. But it doesn't always works when I change it by selecting the value from the list. I supose that that happens because of some option that I change while I'm working but I can't find out witch one exactly.The code that I think that its implicated:

Sub Worksheet_Change(ByVal Target As Range)
If InRange(Target, Range("AngleConf")) Then
Call resistance 'Actualiser le r�sultat mecanique

Winforms Flickering While Drawing Image On Taskbar?

Sep 8, 2010

Right now I'm drawing a small 16x16 image on the title bar of my window. It works nicely, except for an obnoxious flicker that I cant figure out how to get rid of. I'm simply drawing the image like this:

Protected Overrides Sub WndProc(ByRef m As Message)
If m.Msg = WM_SIZE Then
wnd_size = New Size(New Point(CInt(m.LParam)))[code]....

Its repainting the entire title bar each time something is changed on it(click, mouseover the corner buttons, etc), and its during the repaint I get the flicker.

Drop Down Combobox, A List Of Options Are Available?

Mar 12, 2012

Is using Public Property the best way to achieve the following.From a drop down combobox, a list of options are available. Each option in the combobox has a number of public properties that need to be associated with it.When a option is selected, the user will then have two buttons that each call a different sub, the appropriate options are passed to the sub.Each option will always have the same properties required to be passed.So I'm looking at something like this.

Public Class Parameters
Public Property server As String
Public Property replica As String
Public Propery path As String
End Class
