creating a folder in VB

[fujiyama17]

Hello,
I am looking for a way to allow users to create a new folder as well as browse for an existing one and allow the user to select it... I have a few options. I would like to allow users to browse the exising folders, and have an option to create one. I have this code that allows the browsing of folders:

Private Sub Command2_Click()
Dim strResFolder As String
strResFolder = BrowseForFolder(hwnd, "Please select a folder.")
If strResFolder = "" Then
Call MsgBox("The Cancel button was pressed.", vbExclamation)
Else
Call MsgBox("The folder " & strResFolder & " was selected.", vbExclamation)
End If
Text1 = strResFolder
End Sub

where strResFolder is declared in an API

there isn't a way that I can have a button similar to the CommonDialog box button for creating a new folder?

Or maybe I can just ask if they want to create a folder, and have them enter the name. Does anyone know of code to do that? Similar to what you see when intalling items into your computer through an installer.

What my target is is a way to allow users to place files with as much ease an accessability as possible. A commondialog box has an option to create a folder, but, the selection of one file is NOT what I am looking for. Jsut a way for users to locate a folder or create one of thier own.

Look in the tips section of VBworld there is a great way to create directory structures. Or the code that Mathew just entered will also work!!!

[Troy Mac]

Never mind the tip section here is the code just add a form and a command button to the form and paste the code into the general section. This will create the Directory's C:\test\directory\vb\tips

Private Type SECURITY_ATTRIBUTES
nLength As Long
lpSecurityDescriptor As Long
bInheritHandle As Long
End Type
Private Declare Function CreateDirectory Lib "kernel32" _
Alias "CreateDirectoryA" _
(ByVal lpPathName As String, _
lpSecurityAttributes As SECURITY_ATTRIBUTES) As Long



Public Sub CreateNewDirectory(NewDirectory As String)
Dim sDirTest As String
Dim SecAttrib As SECURITY_ATTRIBUTES
Dim bSuccess As Boolean
Dim sPath As String
Dim iCounter As Integer
Dim sTempDir As String
Dim iFlag
iFlag = 0
sPath = NewDirectory + "\x"

If Right(sPath, Len(sPath)) <> "" Then
sPath = sPath & ""
End If

iCounter = 1

Do Until InStr(iCounter, sPath, "") = Len(sPath)
iCounter = InStr(iCounter, sPath, "")
sTempDir = Left(sPath, iCounter)
sDirTest = Dir(sTempDir)
iCounter = iCounter + 1
If Right(sTempDir, 1) <> "\" Then GoTo Missit
'create directory
SecAttrib.lpSecurityDescriptor = &O0
SecAttrib.bInheritHandle = False
SecAttrib.nLength = Len(SecAttrib)
bSuccess = CreateDirectory(sTempDir, SecAttrib)
Missit:
Loop


End Sub


Private Sub Command1_Click()
Call CreateNewDirectory("C:\test\directory\vb\tips")
End Sub

Didn't think anyone saw that. But here it is again:

Private Sub Command1_Click()
Dim x
x = Inputbox("Directory to create?", "Folder:")
If x = "" Then Exit Sub
MkDir x
End Sub

I have to tell you, Matt's is a lot easier than Troy's, but they both to the same thing, create the folder. Is there any way that I can have them search for a particular directory or even folder to create a folder within that instead of typing the whole thing out? That is what both codes do as of now. Could I integrate this code into the box that comes up using Matt's code and then have that fill into the box, so that all the user has to do is name the new folder?

Private Sub Command2_Click()
Dim strResFolder As String
strResFolder = BrowseForFolder(hwnd, "Please select a folder.")
If strResFolder = "" Then
Call MsgBox("The Cancel button was pressed.", vbExclamation)
Else
Call MsgBox("The folder " & strResFolder & " was selected.", vbExclamation)
End If
Text1 = strResFolder
End Sub

That allows me to browse in folders. Thank you for your help again!!

I am sorry.. That was really wordy. All that I am looking for is a way to search for a particular folder, and then allow the user to create a new one within the folder or drive that has been searched. I am just trying to make it easier for the user so that they don't have to type the whole thing out. Thanks!

Nope, I understand what your trying to do and it is pretty easy.

Assuming you have the BrowserForFolder code..even though I'm going to give it anyway. Here is what you want to do:

Option Explicit 

Public Type BrowseInfo 
hwndOwner As Long 
pIDLRoot As Long 
pszDisplayName As Long 
lpszTitle As Long 
ulFlags As Long 
lpfnCallback As Long 
lParam As Long 
iImage As Long 
End Type 

Public Const BIF_RETURNONLYFSDIRS = 1 
Public Const MAX_PATH = 260 

Public Declare Sub CoTaskMemFree Lib "ole32.dll" (ByVal hMem As Long) 
Public Declare Function lstrcat Lib "kernel32" Alias "lstrcatA" (ByVal lpString1 As String, ByVal lpString2 As String) As Long 
Public Declare Function SHBrowseForFolder Lib "shell32" (lpbi As BrowseInfo) As Long 
Public Declare Function SHGetPathFromIDList Lib "shell32" (ByVal pidList As Long, ByVal lpBuffer As String) As Long 


Public Function BrowseForFolder(hwndOwner As Long, sPrompt As String) As String
     
    'declare variables to be used
     Dim iNull As Integer
     Dim lpIDList As Long
     Dim lResult As Long
     Dim sPath As String
     Dim udtBI As BrowseInfo

    'initialise variables
     With udtBI
        .hwndOwner = hwndOwner
        .lpszTitle = lstrcat(sPrompt, "")
        .ulFlags = BIF_RETURNONLYFSDIRS
     End With

    'Call the browse for folder API
     lpIDList = SHBrowseForFolder(udtBI)
     
    'get the resulting string path
     If lpIDList Then
        sPath = String$(MAX_PATH, 0)
        lResult = SHGetPathFromIDList(lpIDList, sPath)
        Call CoTaskMemFree(lpIDList)
        iNull = InStr(sPath, vbNullChar)
        If iNull Then sPath = Left$(sPath, iNull - 1)
     End If

    'If cancel was pressed, sPath = ""
     BrowseForFolder = sPath

End Function

Private Sub Command1_Click() 
Dim strResFolder As String 
Dim x
x = Inputbox("What is the name of the folder you would like to create?")
If x = "" Then Exit Sub
strResFolder = BrowseForFolder(hWnd, "What directory would you like the folder to be created in?") 
If strResFolder <> "" Then 
MkDir strResFolder & "\" & x
Else 
Msgbox "Cancel was pressed! Folder was not created!", 16
Exit Sub
End If 
End Sub

Hat's off to you Matt. The coding works great.

[theman32x]

is there such a thing as "deldr" in order to delete a folder?

[fujiyama17]

theman, I haven't heard of it, nor could I find anything about that particular command I did find one thing though...

Private Sub Command10_Click()
Dim fso As New FileSystemObject
' Create a new folder with the FileSystemObject object.
fso.CreateFolder ("c:\Bogus")
' Get rid of the newly-created folder.
fso.DeleteFolder ("c:\Bogus")
Debug.Print "Deleted folder C:\Bogus"
End Sub

I hope that helps.



Bit of a new problem though, in concern with the code that Matt sent me. Here it is under the command_click

Private Sub Command3_Click()
Dim strResFolder As String
Dim x
x = InputBox("What is the name of the folder you would like to create?")
If x = "" Then
MsgBox "Please Choose the other button to browse a folder", vbExclamation
Exit Sub
Else
strResFolder = BrowseForFolder(hwnd, "What directory would you like the folder to be created in?")
End If
If strResFolder <> "" Then
MkDir strResFolder & "\" & x
MsgBox "You have choosen to place the file(s)/folders in the " & x & " folder under the directory " & strResFolder & "", vbExclamation
Text1 = strResFolder & "\" & x
Else
MsgBox "Cancel was pressed! Folder was not created!", 16
Exit Sub
End If
End Sub

The problem is that the user creates a folder, but then can't directly put it on a drive that is selected (i.e. "H:\" ). The user has to select a folder within the drive (i.e. "H:\app\"). I believe it has to do with the part of the code that is:

If strResFolder <> "" Then
MkDir strResFolder & "\" & x

b/c then you are mapping something like H:\\apps (this is my guess!!)

I don't know what is the best way to fix this. If you oculd help me that would be great. I didn't put what I declared here to tap into the API's... I didn't think that that was the problem. I could be though. Thanks again for your help.

There is no one out there that can help? What's up with that? I am sure there is a guru that knows how this stuff works...

theman32x, there is no such command. There is a command to remove a folder though. RmDir and here its very easy to use.

RmDir "C:\MyDir"

Here is the solution to what you want to do fujiyama17.

I included the Replace function only because I don't have VB6 yet and I needed to use it in order to rearrange the code around.

Public Function Replace(sIn As String, sFind As String, sReplace As String, Optional nStart As Long = 1, Optional nCount As Long = -1, Optional bCompare As VbCompareMethod = vbBinaryCompare) As String
    Dim nC As Long, nPos As Integer, sOut As String
    sOut = sIn
    nPos = InStr(nStart, sOut, sFind, bCompare)
    If nPos = 0 Then GoTo EndFn:
    Do
        nC = nC + 1
        sOut = Left(sOut, nPos - 1) & sReplace & Mid(sOut, nPos + Len(sFind))
        If nCount <> -1 And nC >= nCount Then Exit Do
        nPos = InStr(nStart, sOut, sFind, bCompare)
    Loop While nPos > 0
EndFn:
    Replace = sOut
End Function

Dim strResFolder As String
Dim x
Dim folder, newfolder
x = InputBox("What is the name of the folder you would like to create?")
If x = "" Then
MsgBox "Please Choose the other button to browse a folder", vbExclamation
Exit Sub
Else
strResFolder = BrowseForFolder(hWnd, "What directory would you like the folder to be created in?")
End If
If strResFolder <> "" Then
folder = Left$(strResFolder, 3)
Debug.Print folder 
'^will tell you which Drive has been selected.
newfolder = Replace(strResFolder, "C:\", "H:\")
'^replaces C:\ with H:\ like you wanted.
MsgBox "You have choosen to place the file(s)/folders in the " & x & " folder under the directory " & newfolder & "", vbExclamation
Text1 = newfolder & "\" & x
Else
MsgBox "Cancel was pressed! Folder was not created!", 16
Exit Sub
End If

[theman32x]

i knew there was a command that short just didn't remember the syntax for it ...

[fujiyama17]

Matthew,
I really appreciate your help on this. It works great except for one prob. I am not wanting to replace C:\ with H:\ . THe problem is that I cannot select a root drvie such as C:\ or H:\ to put the created folder in. It has to be put into another folder within that drive to be saved. Can I make it so that I can select the drive and not have to select a folder within the drive to place the new folder? I have about 15 different drives that documents can be placed into. Thanks! Oh, uh, anyone's help is apprecated on this. Thank you!

~Brian

I don't think there is a Drive Dialog box, but you can do something like this:

Dim strDrive As String
Dim x
Dim folder, newfolder
x = InputBox("What is the name of the folder you would like to create?")
If x = "" Then
MsgBox "Please Choose the other button to browse a folder", vbExclamation
Exit Sub
Else
strDrive = BrowseForFolder(hWnd, "What Drive would you like the folder to be created in?")
End If
Drive = Len(strDrive)
If Drive > 3 Then
MsgBox "You have chosen a folder and not a Drive!  Please choose a Drive instead!", vbCritical
Exit Sub
End If
If strDrive <> "" Then
MsgBox "You have choosen to place the file(s)/folders in the " & x & " folder under the " & strDrive & " drive.", vbExclamation
Else
MsgBox "Cancel was pressed! Folder was not created!", vbCritical
Exit Sub
End If

Or an even better way might be to have the user type in the Drive he/she wants.

Dim StrDrive As String
Dim x
x = InputBox("What is the name of the folder you would like to create?")
If x = "" Then
MsgBox "Please Choose the other button to browse a folder", vbExclamation
Exit Sub
Else
StrDrive = InputBox("What Drive would you like the folder to be created in?", , "C:\")
End If
If Len(StrDrive) > 3 Or Len(StrDrive) < 3 Then
MsgBox "You have typed in a Drive that does not exist!", vbCritical
Else
If StrDrive <> "" Then
'MkDir strDrive & "\" & x
MsgBox "You have chosen to place the file(s)/folders in the " & x & " folder under the Drive:  " & StrDrive & "", vbExclamation
Text1 = StrDrive & "" & x
Else
MsgBox "Cancel was pressed! Folder was not created!", 16
Exit Sub
End If
End If

Sweetness,
I'll try the coding out.
