This Nuget contains extensions of UWP classes.

UwpMethods

Helper methods, used in this Nuget.

Function GetAppVers() As String     ' x.y.z (major, minor, build)
Function GetBuildTimestamp(bWithTime As Boolean) As String ' date in "yyyy.MM.dd HH:mm" format

Extensions

Many extensions for UWP classes.

UI related

StorageFolder.OpenExplorer()
Uri.OpenBrowser()
Uri.OpenBrowser(bForceEdge As Boolean)
WebView.GetDocumentHtmlAsync() As String

TextBlock.ShowAppVers(withDebug As Boolean) ' sets Text to x.y.z
Page.ShowAppVers(withDebug As Boolean)  ' creates TextBox in row=1 with app version

MAUI style calls

Page.GoBack()
Page.Navigate(sourcePageType As Type)
Page.Navigate(sourcePageType As Type, parameter As Object)
FrameworkElement.Show()
FrameworkElement.Show(show As Boolean)
FrameworkElement.Hide()

ProgressRIng and Bar

These methods are for:

1. ProgressRing, centered on Page, sized 50 % of Page, with TextBox for messages in center of Ring
2. ProgressBar, on top of last Page.Grid.Row

First, you should Init this, telling what should be created (Ring, and/or Bar):

Page.ProgRingInit(bRing As Boolean, bBar As Boolean)

Then, you can show/hide it. Calls can be nested, i.e. sequence: Show(true); Show(true); Show(false) would not hide Ring/Bar.

Page.ProgRingShow(bVisible As Boolean, bForce As Boolean = False, dMin As Double = 0, dMax As Double = 100)

Any text can be shown on page center:

Page.ProgRingSetText(message As String)

Other methods (for ProgressBar):

Page.ProgRingSetMax(dMaxValue As Double)
Page.ProgRingSetVal(dValue As Double)
Page.ProgRingInc()

file system helpers

All these methods are marked as obsolete; you should not use them in your new apps - instead, try to use System.IO methods (to make portable code).

StorageFile.WriteAllTextAsync(sTxt As String)   ' using Utf8 encoding
StorageFile.AppendLineAsync(sTxt As String)     ' appends string and \r\n to file, using Utf8 encoding
StorageFile.AppendStringAsync(sTxt As String)     ' appends string to file, using Utf8 encoding
StorageFile.ReadAllTextAsync() As String

StorageFolder.WriteAllTextToFileAsync(sFileName As String, sTxt As String, oOption As CreationCollisionOption = FailIfExists)
StorageFolder.ReadAllTextFromFileAsync(sFileName As String) As String

StorageFolder.FileExistsAsync(sFileName As String) As Boolean
