Retrieve Image From Web And Show In Picturebox On Listview Selection Event?
Aug 12, 2010
whats the quickest and least application hogging way to retrieve image from web and show in picturebox on listview selection event?
Heres the code i have already which produces app lag for abut 3-5 seconds per image loaded, i think as it stretches the image to fit into picturebox (which is needed)
vb Private Sub bwGetScreen_RunWorkerCompleted(ByVal sender As System.Object, ByVal e As System.ComponentModel.RunWorkerCompletedEventArgs) Handles bwGetScreen.RunWorkerCompleted
For l As Integer = 0 To ListView2.Items.Count - 1 'start download selected If ListView2.Items(l).Selected = True Then Dim fileid As String = ListView2.Items(l).SubItems(5).Text.ToLower Dim recordid As String = ListView2.Items(l).SubItems(6).Text.ToLower + 1 urlpic = "http://se-board.com/index.php?app=downloads&module=display§ion=screenshot&full=1&id=" & fileid.ToString() & "&record=" & recordid.ToString()

Both images are in .gif format and the small image background is transparent.I set the picturebox's backcolor for small image to transparent, but I only get the backcolor of the form in stead of the big image.Is there anyway to see the big image at the transparent area of small image?

This is for my really advanced game maker. Which is really working well. But when I went to remake the game player and speed it up, I quit painting the map on the form and the char. So my idea now is the make a picturebox on the form contain the map image and then make another picturebox on top of that one. Now the first pictreubox contrains controls the user created, very useful thats why I switched to a picturebox. And the second one contains the char,anyway, The one that contains the char needs to be able to show the controls behind it, or my game maker wont work. The char image its self is transparent but I need to make that picturebox show all the controls behind it so that if that picturebox moves onto a user control they can still see it beneath the char.

I have designed this app with 5 pictureboxes. Each picturebox shows an image of a variation of a particular chord. Now, when a user types in (let's say) Cmajor (and it auto completes) how do I get the 5 pictureboxes to show the 5 different Voicing (Variations) of the Cmajor Chord?

I have 52 listview items in my listview1 and I have a picturebox basically I want it where I can click on a single item in the listview and display an image from a url in the picturebox. I basically have it right now that when you click on any item in the listview it just shows the same image in the picturebox no matter which item it is. I need to figure out how to do it separately for each item.

I 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.

I have a program I'm working on that, for one of the features, allows the user to drag an image from a picturebox, into the main form space, anywhere they want. [code]...
When trying to drag the image from the CurrentTilePicBox, the very moment I move the mouse while dragging the cursor becomes a circle with a cross and won't drag and drop into the new picturebox.

I am having trouble to make a form that displays the picture of the student which all his info is in a datagrid. I used the following
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
' TODO: This line of code loads data into the 'BdSyngentaDataSet.Training' table. You can move, or remove it, as needed
[Code].....
It worked. But, when i click on the next student and go back to the previous, the picture is not there. When I stop the debugging and start again the picture is there but it stops displaying again after going back and forward.

When setting the selection of a RichTextBox, the selected text is highlighted even though I set the HideSelection property to True. Once the RTB loses focus then the selected text is no longer highlighted. Programatically setting the focus to another control doesn't hide the selection, only physically clicking another control will hide it. So is there a way I can make the RTB not show the selection right from the start?
