Hallo,

wir haben einen USB-Barcodescanner getest der am PC normal funktioniert. Benutzt man ihn am PicoMod, bekommt man bestenfalls ein (CR) zurück, mehr ist ihm aber nicht zu entlocken.

Eine Idee woran das liegen kann?

bzw. geht das überhaupt?

Oder gibt es ein Modell, welches jemand empfehlen kann, das funktioniert?

Hi,

the code for VB.net, but without errorhandling:

Quote

Public Class Form1
<DllImport("coredll.dll")> Private Shared Function GetSystemMemoryDivision( _
ByRef lpdwStorePages As Integer, _
ByRef ldpwRamPages As Integer, _
ByRef ldpwPageSize As Integer) As Integer
End Function

<DllImport("coredll.dll")> Private Shared Function SetSystemMemoryDivision( _
ByVal dwStorePages As Integer) As Integer
End Function

Public Shared Sub SetMemory(ByVal division As Integer)
Dim storePages, ramPages, pageSize, totalPages As Integer
If GetSystemMemoryDivision(storePages, ramPages, pageSize) = 1 Then
totalPages = storePages + ramPages
storePages = CInt(totalPages * (100 - division) / 100)
Call SetSystemMemoryDivision(storePages)
End If
End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'Set Memory 90%
SetMemory(90)
End Sub
End Class

Hi,

i got the same Problems. And i tried it with the dependency without any success. My solution was a small delay (1s) in the Application Sub Main(). Antoher solution ist to check is the API ready.

This test should be done in the entry point of the application, before it begins to do any functionality. Again, it depends on the application. It could be enough with:

while(!IsAPIReady(SH_SHELL))
Sleep(500);
