Consider this json file(TESTKill.json):
{
"CLT_PROD": {
"CLRDIR": "C:\\Test",
"CLREXE": "notepad.exe"
},
"CLT_PROD_GHOST": {
"CLRDIR": "C:\\Kontrolle",
"CLREXE": "powershell.exe"
},
"CLTc_PROD_Test1": {
"CLRDIR": "D:\\Kontrolle",
"CLREXE": "powershell.exe"
},
"CLT_PROD_Test2_GHOST": {
"CLRDIR": "F:\\Kontrolle",
"CLREXE": "powershell.exe"
},
"CLT_PROD_Test3_GHOST": {
"CLRDIR": "J:\\ABU",
"CLREXE": "powershell.exe"
}
}
I want to give only the object names(CLT_PROD, CLT_PROD_GHOST, etc.) in a dropdown list in the GUI. I have the following code for this purpose:
$CLRJson = Get-Content -Raw -Path "C:\Temp\TESTKill.json" | ConvertFrom-Json
$CLRObjects = $CLRJson.psobject.Properties.name #select only the object names.
$objDropDownDBSchma = New-Object System.Windows.Forms.ComboBox
$objDropDownDBSchma.Location = New-Object System.Drawing.Size(40,40)
$objDropDownDBSchma.Size = New-Object System.Drawing.Size(200,20)
$objForm.Controls.Add($objDropDownDBSchma)
#Objekte aus der json-Datei in die DropDown Liste hinzufügen
Foreach ($CLRObjekte in $CLRObjects) {
$objDropDownDBSchma.items.Add($CLRObjekte)
}
It works till here. I can select one object from the dropdown menu. The thing I want to have now is, after i choosed one object, i want to click a button and as a result, i should be able to get the values of the two variables "CLRDIR" & "CLREXE" of the appropriate object. For instance: if i had chosen the object "CLT_PROD_GHOST", i want to show the the value of those variables of this object in a text box. I don't know, how to script this. Anyone got any Idea ?
Thx for your help:)
CodePudding user response:
You read the value of the selected item from the dropdown menu.
This will give the name of the property you want to access. Then powershell
can dynamically access the property from $CLRJson
.
I don't remember exactly how to access the selected item of the drowdown menu.
You have also to register a scriptblock in the OnClick
event handler for the Button
you speak about that may contain something like this:
$name = $objDropDownDBSchma.SelectedItem.Value
$CLRObj = $CLRJson.$name
Write-Host $CLRObj.CLRDIR
Write-Host $CLRObj.CLREXE
