Quick question, I've developed a Forum specific C# WPF WebBrowser, for Windows 7.
I have completed so far for the Taskbar:
Tabbed thumbnails
Jumplists
Icon Overlay
Now as the WebBrowser uses the IE engine when a download is started the progress dialog is disp开发者_JS百科layed, what i want is for the progress to be reflected in the Taskbar Button of my application.
Is this acheivable? Thanks
I believe this is something that Scott Hanselman covered in one of his weekly source code blogs.
Not sure if that was what you were looking for or not.
I know how to put it in the Taskbar, i just need to catch the download progress so i can show the progress in the taskbar. Heres a snippet of how i get it to show navigation, the file copy is displayed without the need for code, shell is picking that up automatically.
#region Background Worker
void backgroundWorker1_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
this.TaskbarItemInfo.ProgressValue = (double)e.ProgressPercentage / 100;
}
void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
if (e.Cancelled == true)
{
this.TaskbarItemInfo.ProgressState = TaskbarItemProgressState.Paused;
}
else if (e.Error != null)
{
this.TaskbarItemInfo.ProgressState = TaskbarItemProgressState.Error;
}
else
{
this.TaskbarItemInfo.ProgressState = TaskbarItemProgressState.None;
}
}
void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
for (int i = 1; i <= 100; i++)
{
Thread.Sleep(100);
this.backgroundWorker1.ReportProgress(i,i.ToString());
}
}
}
}
#endregion
All thats needed for the Navigation is:
private void Browser_Navigated(object sender, WebBrowserNavigatedEventArgs e)
{
if (backgroundWorker1.IsBusy == false)
{
backgroundWorker1.RunWorkerAsync();
TaskbarItemInfo.ProgressState = TaskbarItemProgressState.Normal;
}
if (tabControl1.TabPages.Count > 10 && tabControl1.SelectedTab != null)
UpdatePreviewBitmap(tabControl1.SelectedTab);
And taken from the Window Load Event:
this.backgroundWorker1.WorkerReportsProgress = true;
this.backgroundWorker1.WorkerSupportsCancellation = true;
this.backgroundWorker1.DoWork += new DoWorkEventHandler(backgroundWorker1_DoWork);
this.backgroundWorker1.RunWorkerCompleted += new RunWorkerCompletedEventHandler(backgroundWorker1_RunWorkerCompleted);
this.backgroundWorker1.ProgressChanged += new ProgressChangedEventHandler(backgroundWorker1_ProgressChanged);
//
TabbedThumbnail preview = new TabbedThumbnail(this.Handle, tabPage.Handle);
//
preview.TabbedThumbnailActivated += new EventHandler<TabbedThumbnailEventArgs>(preview_TabbedThumbnailActivated);
preview.TabbedThumbnailClosed += new EventHandler<TabbedThumbnailEventArgs>(preview_TabbedThumbnailClosed);
preview.TabbedThumbnailMaximized += new EventHandler<TabbedThumbnailEventArgs>(preview_TabbedThumbnailMaximized);
preview.TabbedThumbnailMinimized += new EventHandler<TabbedThumbnailEventArgs>(preview_TabbedThumbnailMinimized);
//
TaskbarManager.Instance.TabbedThumbnail.AddThumbnailPreview(preview);
//
tabControl1.SelectedTab = tabPage;
TaskbarManager.Instance.TabbedThumbnail.SetActiveTab(tabControl1.SelectedTab);
//
scrollEventAdded = false;
Hope this makes sense. Thanks
