.Synopsis Replaces specified dependencies in an application file .Description Investigates whether the application file contains dependencies to a specific application ID and replaces the dependency if that is the case .Parameter Path Path of the application file to investigate .Parameter Destination Path of the modified application file, where dependencies was replaced (default is to rewrite the original file) .Parameter replaceDependencies A hashtable, describring the dependencies, which needs to be replaced .Parameter showMyCode With this parameter you can change or check ShowMyCode in the app file. Check will throw an error if ShowMyCode is False. .Example Replace-DependenciesInAppFile -containerName test -Path c:\temp\myapp.app -replaceDependencies @{ "437dbf0e-84ff-417a-965d-ed2bb9650972" = @{ "id" = "88b7902e-1655-4e7b-812e-ee9f0667b01b"; "name" = "MyBaseApp"; "publisher" = "Freddy Kristiansen"; "minversion" = "1.0.0.0" }} #> Function Replace-DependenciesInAppFile { Param ( [string] $containerName = $bcContainerHelperConfig.defaultContainerName, [Parameter(Mandatory=$true)] [string] $Path, [string] $Destination = $Path, [hashtable] $replaceDependencies = $null, [ValidateSet('Ignore','True','False','Check')] [string] $ShowMyCode = "Ignore", [switch] $replacePackageId ) $telemetryScope = InitTelemetryScope -name $MyInvocation.InvocationName -parameterValues $PSBoundParameters -includeParameters @() try { if ($path -ne $Destination) { Copy-Item -Path $path -Destination $Destination -Force $path = $Destination } Invoke-ScriptInBCContainer -containerName $containerName -scriptBlock { Param($path, $Destination, $replaceDependencies, $ShowMyCode, $replacePackageId) add-type -path (Get-Item "C:\Program Files\Microsoft Dynamics NAV\*\Service\system.io.packaging.dll").FullName $memoryStream = $null $fs = $null try { $fs = [System.IO.File]::OpenRead($Path) $binaryReader = [System.IO.BinaryReader]::new($fs) $magicNumber1 = $binaryReader.ReadUInt32() $metadataSize = $binaryReader.ReadUInt32() $metadataVersion = $binaryReader.ReadUInt32() $packageId = [Guid]::new($binaryReader.ReadBytes(16)) $contentLength = $binaryReader.ReadInt64() $magicNumber2 = $binaryReader.ReadUInt32() if ($magicNumber1 -ne 0x5856414E -or $magicNumber2 -ne 0x5856414E -or $metadataVersion -gt 2 -or $fs.Position + $contentLength -gt $fs.Length) { throw "Unsupported package format" } $memoryStream = [System.IO.MemoryStream]::new() $fs.Seek($metadataSize, [System.IO.SeekOrigin]::Begin) | Out-Null $fs.CopyTo($memoryStream) $memoryStream.Seek(0, [System.IO.SeekOrigin]::Begin) | Out-Null $memoryStream.SetLength($contentLength) $fs.Close() $fs.Dispose() $fs = $null $package = [System.IO.Packaging.Package]::Open($memoryStream, [System.IO.FileMode]::Open, [System.IO.FileAccess]::ReadWrite) $manifestPart = $package.GetPart('/NavxManifest.xml') $manifest = [xml]([System.IO.StreamReader]::new($manifestPart.GetStream())).ReadToEnd() $changes = $false if ($ShowMyCode -ne "Ignore") { if ($ShowMyCode -eq "Check") { if ($manifest.Package.App.ShowMyCode -eq "False") { throw "Application has ShowMyCode set to False" } } elseif ($manifest.Package.App.ShowMyCode -ne $ShowMyCode) { Write-Host "Changing ShowMyCode to $ShowMyCOde" $manifest.Package.App.ShowMyCode = "$ShowMyCode" $changes = $true } } if ($replaceDependencies) { $manifest.Package.Dependencies.GetEnumerator() | % { $dependency = $_ if ($replaceDependencies.ContainsKey($dependency.id)) { $newDependency = $replaceDependencies[$dependency.id] Write-Host "Replacing dependency from $($dependency.id) to $($newDependency.id)" $dependency.id = $newDependency.id $dependency.name = $newDependency.name $dependency.publisher = $newDependency.publisher $dependency.minVersion = $newDependency.minVersion $changes = $true } } } if ($replacePackageId) { $packageId = [Guid]::NewGuid() $changes = $true } if ($changes) { $partStream = $manifestPart.GetStream([System.IO.FileMode]::Create) $manifest.Save($partStream) $partStream.Flush() $package.Close() $fs = [System.IO.FileStream]::new($Destination, [System.IO.FileMode]::Create) $binaryWriter = [System.IO.BinaryWriter]::new($fs) $binaryWriter.Write([UInt32](0x5856414E)) $binaryWriter.Write([UInt32](40)) $binaryWriter.Write([UInt32](2)) $binaryWriter.Write($packageId.ToByteArray()) $binaryWriter.Write([UInt64]($memoryStream.Length)) $binaryWriter.Write([UInt32](0x5856414E)) $memoryStream.Seek(0, [System.IO.SeekOrigin]::Begin) | Out-Null $memoryStream.CopyTo($fs) $fs.Close() $fs.Dispose() $fs = $null } else { if ($Path -ne $Destination) { Copy-Item -Path $Path -Destination $Destination -Force } } } finally { if ($fs) { $fs.Close() } } } -argumentList (Get-BCContainerPath -containerName $containerName -path $path -throw), (Get-BCContainerPath -containerName $containerName -path $Destination -throw), $replaceDependencies, $ShowMyCode, $replacePackageId } catch { TrackException -telemetryScope $telemetryScope -errorRecord $_ throw } finally { TrackTrace -telemetryScope $telemetryScope } } Export-ModuleMember -Function Replace-DependenciesInAppFile |
