[RESOLVED] i'm tryng clean a string without sucess:(

heres my MouseIcon property:

Code:

---

Public Property Let MouseIcon(ByVal vNewValue As String)
    strMouseIcon = vNewValue
    If strMouseIcon = "" Then
        UserControl.MousePointer = 0
        RestoreLastCursor
        Exit Property
    End If
    If ValidMouse(UCase(strMouseIcon)) = False Then Exit Property
    If UCase(strMouseIcon) Like "*.ANI" = True Then
        If Ambient.UserMode = True Or blnEnter = True Then
            SaveLastCursor
            StartAnimatedCursor strMouseIcon
        End If
    Else
        If strMouseIcon <> "" Then
            UserControl.MousePointer = 99
            UserControl.MouseIcon = LoadPicture(strMouseIcon)
        Else
            RestoreLastCursor
            UserControl.MousePointer = 0
        End If
    End If
    PropertyChanged "MouseIcon"
End Property

---

and heres the module for work with animated cursors:

Code:

---

Option Explicit

Private Declare Function LoadCursorFromFile Lib "user32" Alias _
    "LoadCursorFromFileA" (ByVal lpFileName As String) As Long
Private Declare Function SetSystemCursor Lib "user32" _
    (ByVal hcur As Long, ByVal id As Long) As Long
Private Declare Function GetCursor Lib "user32" () As Long
Private Declare Function CopyIcon Lib "user32" (ByVal hcur As Long) As Long
Private Const OCR_NORMAL = 32512
Private mlngOldCursor As Long
Private lngNewCursor As Long

Public Sub SaveLastCursor()
    mlngOldCursor = CopyIcon(GetCursor())
End Sub

Public Sub StartAnimatedCursor(AniFilePath As String)
    lngNewCursor = LoadCursorFromFile(AniFilePath)
    SetSystemCursor lngNewCursor, OCR_NORMAL
End Sub

Public Sub RestoreLastCursor()    'Restore last cursor
    SetSystemCursor mlngOldCursor, OCR_NORMAL
End Sub

---

to be honestly my property is empty, but the strMouseIcon still having the valeu. sometimes i don't understand somethings.
can anyone explain to me what isn't right?
thanks

i don't understand

What do you mean "clean a string"? You empty a string by setting it to vbNullString. Nowhere in your posted code are you doing that. The only way strMouseIcon can be empty is if it is passed that way to your property as vNewValue

ín these case the vNewValue is ""(empty).
but in debug is showed the strMouseIcon value.
why these is appen?

Recommend searching your project for lines like: strMouseIcon =
You might be setting the variable elsewhere in your project.

ok. i will try. but why i don't recive the value in property page section and in porperty window?

Maybe you should show us your Property Get MouseIcon routine?

Using Debug.Print, keep in mind that if you have multiple controls and the strMouseIcon value you are getting may not be for the control you think you are debugging? Just a thought. Maybe change your debug.print statement to:
Debug.Print strMouseIcon, Ambient.DisplayName

but way i recibe the strvalue with debug, but not in property get part?
my objective is show the anime cursor, when the mouse is in UC, but in these case the porperty don't have any value. then why with Debug key word i can get the value(but not right value)?

i try what you said, and yes it's the control name, that i know where is the error(where i change(before) the mouseicon value.

When the mouse is in the UC when? At design time, at runtime? There are no mousemove events when form is in design time.

Again, search your project to see if you are resetting strMouseIcon elsewhere. Are you changing the property in your form? Maybe in the MouseEnter event or other events? Those are places to check too.

"When the mouse is in the UC when? At design time, at runtime? There are no mousemove events when form is in design time."
in run-time. and after change the property, the icon is only showed in run-time.

Ok, are you saying that when you pass vNewValue as "", strMouseIcon keeps its original value? That isn't possible, and this should prove it.

Change: Debug.Print strMouseIcon
To: Debug.Print ">"; strMouseIcon; "<", ">"; vNewValue; "< Equal? "; (strMouseIcon = vNewValue)
