VS 2005 How To Call Fastboot From .net
Feb 14, 2011this is my very first post here (so please be gentle)I'm somewhat new to VB and a bit familiar with Android fastboot command structure. I have googled how to call commands from VB but most of the info I found has to do with DOS CMD.exe and most people simply recommended to batch my scripts then call them using shell(<nameOf.bat>)I am looking for a smarter way to use VB.net to call a process and to interact with it, get strings into it so I can create customized fastboot command (like flash XXX or SeRev etc), and have my program, menu driven so it's simple to use.I am running into issue understanding how to set a process, then call it when its not CMD.exe.
View 4 RepliesImport And Call Unmanaged C Dll With Ansi String "char *" Pointer String From .net?
Mar 11, 2010I have written my own function, which in C would be declared like this, using standard Win32 calling conventions:int Thing( char * command, char * buffer, int * BufSize);I have the following amount of VB figured out, which should import the dll and call this function, wrapping it up to make it easy to call Thing("CommandHere",GetDataBackHere).UPDATE:This code is now a working solution, as shown here:
Imports Microsoft.VisualBasic
Imports System.Runtime.InteropServices
Imports System
Imports System.Text
[Code]...
Updates: I got the code to build by following the help received here, and then I had forgot the As Return Type (which got me a MarshalDirectiveException PInvokeRestriction). Then I had an assertion failure inside my DLL, which lead to an SEHException. Once fixed, this works BEAUTIFULLY. There are newsgroups where people are saying this can not be done, that VB only loads managed dll assemblies (which I guess is the normal thing most VB users are used to).

View 4 RepliesVS 2005 - Return Value From Asynchronous Web Service Call
Aug 13, 2009I'm using ASMX web services in VB.Net in VS 2005. I am calling a function method on the web service that returns a true or false value. This works fine if I call the the web method synchronously, but if I want to call the method asynchronously, the function returns to a sub and there is no return value; therefore, I can't tell whether the result of call is true or false. Is there a way to make an asynchronous call and still get the true or false result (perhaps using the userState Object)?
For Example:
Dim MyResult as Boolean = MyService.GetResult(10)
Dim MyResult as Boolean = MyServer.GetResultAsync(10)
This doesn't work the compiler complains: "Expression Does Not Produce a Value"

Read A String And Call The Method Of The Same Name?
Nov 2, 2009Is it possible to read a string and call the method of the same name?For example: I have many buttons and if the user presses the button named A1, I want the Sub AI() to be called. I don't want to do an explicit If-Then for each button. Rather a common ONCLICK method that is called by all buttons and another method (the same name as the name of the button) is called.
Example:
Sub Click(byVal buttonName as string)
call ButtonName ' <<<< Error. ButtonName is string and not a Method.
End Sub
[2005] Application - Voice Modem Basics - How To Detect When The Call Is Answered Though
Jan 30, 2009I spent some time with data modems till I realized it's a voice modem that I'm going to need in my application. I see that there are some other commands for a voice modem, although nothing very elaborate. I would imagine you make the call as you would in a data modem ATDT etc and it looks like there is really just one command to send audio...
AT+VTX
AT#VTX
Not sure what this is all about except maybe just different standards? Still not sure about how to detect when the call is answered though. I won't be talking to another modem. Maybe the serial port itself has a pin change or something? You would think there would be a bit "somewhere" that the modem would generate when it quits ringing. I may have build my own outboard box to do this. (easy enough -- probably more reliable too -- modems sure need rebooting a lot it seems).
Here is the goal though --Voice modem calls out, call is answered, and I inject my audio from the PC sound card for a minute or so and then tell the modem to hangup.
