c# - OpenFileDialog - How to prevent the default directory from being overwritten? -


i'm trying find way reset initial/default directory after closing openfiledialog. consider following example:

using (openfiledialog openfile = new openfiledialog()) {     // example: opens in 'desktop' directory     // user navigates 'documents' directory in form before selecting file     dialogresult result = openfile.showdialog();     if (result == dialogresult.ok) messagebox.show(openfile.filename); }  // somewhere else, code runs using (openfiledialog openfile = new openfiledialog()) {     // problem: opens in 'documents' directory. not good!     // how open using same default directory (ie: desktop)?     dialogresult result = openfile.showdialog();     if (result == dialogresult.ok) messagebox.show(openfile.filename); }

just clear, 'desktop' example, won't know initial directory it's stored in registry (if understand correctly).

i tried using restoredirectory option. did not seem have effect. i've read elsewhere it's supposed reset environment.currentdirectory original value, sounds reasonable. however, don't think openfiledialog uses environment.currentdirectory since value never changed, , never matches openfiledialog opens (unless manually browse it).

is there might missing here? know how stop overwriting whichever directory variable openfiledialog uses default?

the default directory stored in following registry key on windows 7.

hkey_current_user\software\microsoft\windows\currentversion\explorer\comdlg32

iirc, different on other os's, might want find out exact directory depending on os version.

so grab value when application launches, , save in memory, , set openfiledialog.initialdirectory every time before open dialog.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
