Assign icon to all forms in a powershell multiform gui with ps2exe

Question

I'm making a Winforms Application in Powershell that has 3 different forms and want to compile it into an .exe with ps2exe. I've used -iconFile for the icon but I'm running into a problem that only the 1st form uses the icon. The 2nd form opens once you press a button in the 1st form but it's using the standard .net winforms icon instead of the icon specified with ps2exe.

Is there any way I can assign the icon to all forms with ps2exe or a different tool? Maybe even in the script itself?

Answer 1

As suggested in the comments, you might just embed your icons in the PowerShell script as follows:

• Load your icon as byte stream:

$Icon = Get-Content .\favicon.ico -AsByteStream

Or, (as for this example,) I am using the (fav)icon from this StackOverflow site:

$Response = Invoke-WebRequest https://cdn.sstatic.net/Sites/stackoverflow/Img/favicon.ico?v=ec617d715196
$Icon = $Response.Content

• Convert your icon to base64

[Convert]::ToBase64String($Icon)

Note that there also several online base64 convertors as: https://www.base64decode.org/

• Copy the results ([Convert]::ToBase64String($Icon) | Clip) and paste it into your script where you assign it to a variable (e.g. $Base64)
• Convert your icon back from Base64
• Assign the icon to your form

$Base64 =
