c# run RegSvr32 programmatically through Windows Form and get its DialogBox's message

i'm creating c# windows form application register and/or unregister dlls programmatically. that, use instance of system.diagnostic.process class. redirect both stdoutput , stderror inside textbox element.

using following code, when reg or unreg managed .dll file (that use regasm.exe) can obtain redirecting goal.

in case of regsvr32.exe problem occurs: regsvr32's resulting dialogbox raises (in both success or error cases)... message totally blank.

so have tried use regsvr32's /s flag option... dialogbox not raise up, nothing becomes written inside textbox.

is there can me solve problem? i'm getting crazy! thanks!

a curious note: i'm stubborn, i've tried register unmanaged dll, using simple code (without /s flag), implementing c# console application... regsvr32 dialog box pretty visible in both success , error cases.

so i've substituted process block code in old code regsvr32 dialog box still not appear!!!

here windows form code:

in form1 class implemented following delegates , methods print inside form1.textbox element stdoutput , stderror:

void appendline( string line )  {    if( textbox.text.length == 0 )      textbox.text = value;    else      textbox.appendtext( "\r\n" + value );  }    void onoutputreceivedevent( object sender, datareceivedeventargs e )  {    appendlinemultithread( e.data );  }    void onerrorreceivedevent( object sender, datareceivedeventargs e )  {    appendlinemultithread( e.data );  }    delegate void appendlinemultithreadhandler( string text );  private void appendlinemultithread( string line )  {    // invokerequired required compares thread id of calling thread thread id of creating thread. if these threads different, returns true.    if(invokerequired )    {      appendlinemultithreadhandler d = new appendlinemultithreadhandler( appendline );      invoke( d,  line );    }    else    {      appendline( line ); // call directly    }  }

inside form1.run() method (it called when user click on run button) each item registers both events, , execute reg or unreg process:

void run()  {    foreach( registereritem in config.regitems )    {      i.errorreceivedevent += onerrorreceivedevent;      i.outputreceivedevent += onoutputreceivedevent;      i.execute();    }  }

and here registereritem.execute() method:

/// <summary>  /// method used register or unregister dll.  /// </summary>  public void execute()  {    string exe = "depending on hidden parameters here have 'regsvr32.exe' or 'regasm.exe'";    string args = "depending on hidden parameters here have '/codebase /s' or '/u /s'";      try    {      using( process reg = new process() )      {        reg.startinfo.filename = exe;        reg.startinfo.arguments = args;        reg.startinfo.useshellexecute = false;        reg.startinfo.createnowindow = true;          reg.startinfo.redirectstandardoutput = true;        reg.startinfo.redirectstandarderror = true;          reg.errordatareceived += onerrordatareceived;        reg.outputdatareceived += onoutputdatareceived;        reg.enableraisingevents = true;        reg.start();        reg.beginerrorreadline();        reg.beginoutputreadline();        //reg.waitforexit(); // commented 'cause @ moment don't care it      }    }    catch( exception exc )    {      throw new exception( exe + " " + args, exc );    }  }    public delegate void datareceivedeventhandler( object sender, datareceivedeventargs e );  public event datareceivedeventhandler errorreceivedevent;  void onerrordatareceived( object sender, datareceivedeventargs e )  {    if( errorreceivedevent != null )      errorreceivedevent( sender, e );  }    public event datareceivedeventhandler outputreceivedevent;  void onoutputdatareceived( object sender, datareceivedeventargs e )  {    if( outputreceivedevent != null )      outputreceivedevent( sender, e );  }

hi,

my suggestion not call such methods.

registering dll (unamanged / com) quite easy. regsvr32 not doing special. loading library , calls dllregisterserver. instead of calling regsvr32 executable, on own, too.

you can find example code at
