Actually , i develop an application in vb.net .
The first step , i want to create a folder and subfolder in google drive (of course i need a test if a folder exist or not ) , then , i want to upload a file in specific folder in google driver

here is my code

VB

Public Sub createfolder()

    Dim dossier = New Google.Apis.Drive.v2.Data.File()

    dossier.Title = dat_sauv.SelectedItem 'title from combobox in forms
    dossier.MimeType = "application/vnd.google-apps.folder"

    Dim rep = Service.Files.Insert(dossier)
    rep.Fields = "id"

    Dim file = rep.Execute()

    'sub folder Creation
    Dim subfolder = New Google.Apis.Drive.v2.Data.File()

    'title from radio button in forms
    If (VT.Checked = True) Then
        subfolder.Title = VT.Text
    ElseIf (vm.Checked = True) Then
        subfolder.Title = VM.Text
    ElseIf (VI.Checked = True) Then
        subfolder.Title = VI.Text
    Else
        subfolder.Title = VF.Text
    End If

    subfolder.MimeType = "application/vnd.google-apps.folder"

    Dim res = Service.Files.Insert(subfolder)
    res.Fields = "id"

    Dim fil = res.Execute()
    dossier.Parents = subfolder

end sub

Solution 1

It does not look like you are passing the Parent folder id to the Subfolder before executing the create folder command...

1 / how and where i do it ?
i called a method createfolder() in button event

2/ for upload file to an specific folder , here is my code

Private Sub UploadFile(FilePath As String)

' la partie de l'import du fichier dans le drive
Dim ByteArray As Byte() = System.IO.File.ReadAllBytes(FilePath) ' lire le fichier dans un tableau d'octet
Dim Stream As New System.IO.MemoryStream(ByteArray) ' lire le bloc d'octet du tableau et écrit les données dans une mémoire temp

' Insertion fichier dans le drive
Dim f As New Google.Apis.Drive.v2.Data.File()
f.Title = fichier_txt.Text
f.Description = " fichier drive"
f.MimeType = "text/plain , image/jpeg"

Dim Up As FilesResource.InsertMediaUpload = Service.Files.Insert(f, Stream, f.MimeType)
Up.Upload() ' la méthode qui fait l'upload dans le drive

MsgBox("Upload Successful ") 'Succés d'upload

End Sub

I created my own API lib for Google Drive API. Looking at the documentation, you set it in the metadata... Work with Folders | Drive REST API | Google Developers[^] - Look at the "Inserting a file in a folder" example... folder works the same...
