关于VB6修改注册表的问题

API就不发了。
下面是一个声明
'写入注册表字符串键值
Public Sub SetString(hKey As Long, strPath As String, strValue As String, strdata As String)
Dim keyhand As Long
RegCreateKey hKey, strPath, keyhand
RegSetValueEx keyhand, strValue, 0, REG_SZ, ByVal strdata, Len(strdata)
RegCloseKey keyhand
End Sub

下面是一行代码，用来添加的
SetString HKEY_LOCAL_MACHINE, "SOFTWARE\Microsoft\Windows\CurrentVersion\Run", "IE老板键", App.Path & "\IE老板键.exe"

结果添加是添加了，值也比较正常，只是后缀名没了。怎么回事？该怎么修改？

RegSetValueEx keyhand, strValue, 0, REG_SZ, ByVal strdata, Len(strdata)

【Len(strdata)】这个有问题。
