I'm trying to figure out how I can change a ListView's "Large ImageList" to another one at runtime. For example I have it attached to my Icons_64x64 ImageList right now but would want an option to switch it to Icons_128x128 at runtime. Hope that makes sense and someone has an idea out there. I haven't been able to come up with anything at all.

When I add an image to the imagelist, the con shows up. That's fine Let's say that I added 4 images (four items to the listview) then remove one item from the listview. From there, the next item I add will adopt the previous image added. How can I keep this from happening?
I've got a list view that opens items inside a folder and displays them. I want to know if there is a way to have the list view display the icons as well, maybe using shell32 or an imagelist. Here's the code:
Imports System.IO
Imports System.Xml
Imports System.Runtime.InteropServices
Imports Microsoft.VisualBasic

View 2 RepliesDoes anyone know if it is possible to resize an imagelist/listview image without repopulating the image list? I am using scroll bar to change the image size from 25 point to 256 point. When I leave the scroll bar the imagelist repopulates from the files list. This can be very slow when working with high resolution pictures. I don't want to limit the image size to 2 sizes by using large and small imagelist.
View 1 RepliesAny snippet of code for adding groups at run-time to a listview. I am currently listing books (and stats) without groups via the following code which is executed in a loop (one pass per book title).
item = New ListViewItem
item.Text = seq.ToString
item.SubItems.Add(Mid(titlenode.Nodes(N_CSTAT).Text, 3))
item.SubItems.Add(Mid(titlenode.Nodes(N_JSTAT).Text, 3))
item.SubItems.Add(titlenode.Nodes(N_PUBLISHED).Text)

The listview is set to details view. What I want to do is group the book titles by series. For example, books by Michael Connelly may be grouped by "Harry Bosch", "Jack McEvoy", "Mickey Haller", etc. I can create a new group for each new series by
groupnum += 1
group = New ListViewGroup("group" & groupnum, _
System.Windows.Forms.HorizontalAlignment.Left)
group.Name = "group" & groupnum
group.Header = series
But I cannot find how to add the group to the listview and add the new item to the associated group.

View 3 RepliesI'm writing an application for a device running Windows XP. There are 2 versions of the device and each version has its own API to communicate with the device's software. The application I'm writing needs to pull the same data from the API. My question is how to write a application that will detect at runtime which version of the device it is on and use the appropriate API.
I've created an interface containing all of the common methods and also classes for each device that implement the interface. Now I need to know how to activate the correct one at runtime.

I'm writing a Windows form application. I created a SQL database called myDB.mdf. The database/form connection was created using the wizard provided by VS2008.

I have multiple urls to the same webservice, each with it's own "token". I need to switch from one url to another during runtime. I have planned to do this by storing my URLs inside a XML-file, and then read it, copy innertext of an element and overwrite the WS url in my app.config. My app reads and write to xml just fine, it is when I actually use a method from the webserivice proplems start to appear.

I am creating a program that will be sold as a subscription. I am trying to decide how to prevent users from passing the program to others without purchasing it. I was thinking that on the very first run, the program could pull the MAC address from the computer it is run on, and create a constant at run time. This constant is then hard wired into the program and is used for comparison every time the program is run thereafter. If the MAC address do not match, it is on a different computer.
How do I recompile my .exe to include a globally declared constant used for comparison? And how do I use this variable throughout my program?Or is there a simpler way to create my program to require Key Codes for renewal once per year?
I did something that when I now load my program(VB 2008), my controls; combo boxes, buttons, progress bar, etc. look like they are from VB 2005 or like VBA buttons, not the rounded edge buttons of 2008.

View 1 RepliesI have a listview control. it has an imagelist attached to it with two images in it. I have entered items into my listview, and they are using the first image in my imagelist.... GREAT! Now, there is a variable I have that will tell me which index in the listview is currently active, noting to do with what I select that could be at another index it's just what's being processed by the program at the time in some task.
Create a function that will change the images of all my listview items by looping through them. If the index variable is set to 2, I want the 3rd item in my list view set to use the 2nd image in my imagelist. The rest of the items in my listview need to be set to the first image in the imagelist.

View 4 RepliesI'm writing a windows form application using vs2008. I need to connect to different SQL server express database files during runtime. There is a "how to do" video showing a technique for this
[Code]...
and then in the Form1_load sub and before calling the data adapter to fill data, insert codes below:
Dim strConnectingSting = NewConnectionString
My.Settings.RunTimeConnectionString = strConnectingSting
The method works but only for the first database. I found once adapter.fill is called and the connection to a database is established, the connection can't be changed.To do what I want, I have to create a startup project to call my main project. When I want to change connection, close the main project and start again.
I'm making a custom control that can be dragged around and it is semi transparent.
