View 2 RepliesI have a window application develpoed in vs 2008, framework 3.5, in which i have put a button.. Now where i click that button the other text boxes are filled up with the data from database thru web service.. what i want is while all text boxes are being filled i want to show an animated loading gif image till data loading is completed in all the text boxes.. i have tried to use image picture box but while data is loading gif image is displyes but in static mode.. cant see animation... i think this is because data loading and animation both are done thru one UI thread..
View 8 RepliesWell after coding a very basic image viewing application all seemed well. All animated .gif files played beautifully, all .png, .jpg, .bmp, etc, initiated well. However I've now, for some unkown reason, hit a snag. The animated .gif files still play, but they crash after a few seconds of play. Providing this error:

Here is my

why it's not working?
Im trying to show animated gif during busy process or loading. but it isn;t working rite. the gif stops to animate when loading instead and animates only when no loading is n progress. what i have done is to show formB from the formA. i load the gif into the picbox in formA and crete a new thread which will be opening another formB.
dim loadThread As Threading.Thread
LoadingGif()
loadThread = New Threading.Thread(AddressOf loadingForm)
loadThread.Start(formB)
but the gif doesn;t move at all unless another form is displayed.
what's the best way to stop a form from displaying in its Load event.I initialise a form using the following code:
Dim MyForm as new MyCustomForm
In the Load event of MyCustomForm, I ask the user to select a folder and use that to populate a listbox on the form.folder.If the user presses Cancel instead of selecting a folder, I don't want to display the form. Right now, I just call Me.Close in the Load event, but that still causes the form to briefly appear and disappear in the background. Also do I need to call Me.Dispose?
Okay, so I have been developing my own MP3 player recently, and now I thought I would make the player remember what songs were in the playlist when it shut down. It now remembers the playlist file that was used last, but I would still rather make it so that it remembers all the songs without saving the playlist.
I've been using a setting to save the playlist file, but when I try this:
...it doesn't work. The savedSongs is a System.Collections.ListArray. Heres the code at Form_Load I'm using at the moment.
Dim loadSongs As New System.Collections.ArrayList
loadSongs = ExperimentalPlayer.My.Settings.savedSongs
lbl_songname.Text = ""
[Code].....
Should I use some other kind of variable to save the filepaths? Well, the other option is that I use a text file for that, but I'd rather make it like this.
Ive been programming in VB6 for years, i figured its time for an upgrade. Here's what im doing, and what the problem is:
Im loading a bunch of pictures on top of one image. They are all PNG files, and some of the images have transparent edges, and some semi-transparency within the image itself.
So basically, i need to be able to load these images on top of the other images, and still maintain the transparency.
Is this possible in VB08? This is one of the main reasons i moved to 08 from vb6, more things possible including multithreading.

View 6 Repliesshow me how to Load an Image that is located in a Folder created on a nother Form. Public Class CroppingForm Private Sub CroppingForm_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load PictureCropper.Picture = Image.FromFile(MainForm.CurrentFilePath, "PreView Photo.bmp")
End Sub The Image that is sepose to be loaded into PictureCropper is named "PreView Photo.bmp"
By using: PictureCropper.Picture = Image.FromFile(MainForm.NewImage)the Image is being loaded correctly.
Unfortunately this is going to be a problem later on, for a Image with a diferent name will allso have to be saved to the before mentiond Folder. That is the reson for var."CurrentFilePath" it mast hold te Folder Path only "D:DIY.ID Photos"

I made two applications the first one calls the other. But the other application takes time to load. Even on a fast Pc. So i was thinking of adding a loading form to it. For example when the other application is done loading the loading form goes away.

Does somebody know where i can get Microsoft's status indicator bar animated image that has a progress bar on it that when it reaches the maximum it goes the other way round.
You can find a small version of it in :c:Program FilesMicrosoft Visual Studio 8Common7VS2005ImageLibraryVS2005ImageLibraryanimationsstatus_anim.gif and it is called
"Indeterminate status indicator bar".
I was thinking is there anyway VB2005 can be done if I create an animation( car) such that its movement can me opearted using another external component(example a sensor).

I can't really figure out how to extract frames and what not from an animated image stored in a picturebox. I made a post earlier similar to this matter. But now I must ask how it is that you work with GetFrame and SetActiveFrame.
View 2 RepliesJust want to know the best method to load a picture in a picture box dynamically. As part of my development, I was supposed to load 4 pictures from network to 4 picturebox controls.
For which, I found, 2 methods.
1. Picturebox1.Image=new bitmap("C:\test.jpg")
(or)
2. Piturebox1.ImageLocation="C:\test.jpg"
Which one is more suitable interms of performance.

I am writing an industrial control front-end that has some "fancy" graphics to indicate the states of some machinery. For example, I indicate that some heaters are on by showing red wavy arrows emanating out from a picture of a heater. I accomplished this by creating a class that inherits from PictureBox and using a timer to advance the images:
Public Class AnimatedPictureBox
Inherits PictureBox
Private WithEvents Timer As New Timers.Timer
Public Property Interval As Double

My question is "Is this an alright way to go about this or is there some obvious better way?" I'm not too good at programming and am worried that having several of these objects with their embedded timers taxing the CPU. I went with animated GIFs for some other animation stuff, but here, I wanted to be able to handle image formats that can handle a larger palette than a GIF (if that makes sense). In other words, when I tried to save some of my animations as GIFs, the image quality took an unacceptable hit.

How can I get my application to load the Sub Main at the start rather than loading a form on start up.
I have tried declaring 'Public Sub Main' on my forms and in some modules, yet in my project properties, it is not one of the options.
I have a DataGridViewImageColumn that should display an image for only certain rows. After I bind a generic list of classes to my datagrid, I loop through each row and update the image cell with an image that is an embedded resource for the rows that require the image. This works great if the form has been fully loaded. However, when I attempt this on form load the image doesn't show up? I also can't perform simpler things such as changing the row background color on form load. Should I be performing this logic in a different event after form load?
For i As Integer = 0 To dgvRoles.Rows.Count - 1
Dim imageStream As System.IO.Stream = Nothing
imageStream = Me.GetType().Assembly.GetManifestResourceStream("MyApplication.Timer.png")
