I'm trying to write a program that will send a keypress (and eventually i will do a mouse move / press also) to an appliction. i tried using the managed sendinput and while it works in normal applications it does NOT work in Directx applications. any suggestions? i am trying to figure out the pinvoke version of SenInput but having very little luck at the moment so if you happen to know what to do in order to get this to work please help.

If it's ANY application...this should do the trick. Just be sure to modify it for what you want...it's straight out of one of my toys.

using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;
using System.Windows.Forms;

namespace wiseKontrol.CommandClasses
{
class InsertText : BaseCommand
{
public InsertText()
{
this.SCommandName = "InsertText";
this.SMenuItemName = "Insert Te&xt";
this.SArgumentHelp = "Enter the text to be inserted:";
}

public const ushort KEYEVENTF_KEYUP = 0x0002;
public const ushort KEYEVENTF_KEYDOWN = 0x0000;
public const ushort KEYEVENTF_SCANCODE = 0x0008;
public const ushort KEYEVENTF_UNICODE = 0x0004;

public struct KEYBDINPUT
{
public ushort wVk;
public ushort wScan;
public uint dwFlags;
public long time;
public uint dwExtraInfo;
};

[StructLayout(LayoutKind.Explicit, Size = 28)]
public struct INPUT
{
[FieldOffset(0)]
public uint type;
[FieldOffset(4)]
public KEYBDINPUT ki;
};


[DllImport("user32.dll")]
public static extern uint SendInput(uint nInputs, ref INPUT pInputs, int cbSize);

public override void executeCommand()
{
INPUT structInput;
structInput = new INPUT();
structInput.type = 1;
structInput.ki.wScan = 0;
structInput.ki.wVk = 0;
structInput.ki.time = 0;
structInput.ki.dwFlags = 0;
structInput.ki.dwExtraInfo = 0;

foreach (char c in SArgument.ToCharArray())
{
structInput.ki.dwFlags = KEYEVENTF_UNICODE;
structInput.ki.wScan = (ushort)c;
SendInput(1, ref structInput, Marshal.SizeOf(structInput));

structInput.ki.dwFlags = KEYEVENTF_UNICODE;
structInput.ki.dwFlags += KEYEVENTF_KEYUP;
structInput.ki.wScan = (ushort)c;
SendInput(1, ref structInput, Marshal.SizeOf(structInput));

}
}
}
}

Yup. go to a text window and it works go to my directx application and it doesn't.

Anyone else have some ideas?

I was thinking maybe throwing in a windowshookex and using the journalplay think like one of the msdn files i was reading said but reading that was like slamming my face into a wall. i got nothing out of it but a headache.

That's odd...I use it just fine in Warcraft III to hold down my alt key for life checking =0 Well good luck finding a solution, I just tossed it out there since I had it lying around.

trying to use it in everquest and so far no luck. no CLUE wth is wrong.

i am relativly certai i tried this (Ox100 or Ox001 i forget which it was that it's defined as) but i will try again. i am nearlly certain what i need to do is either hook in and inject my own code (ala another post on this board from almost 2 years ago) OR provide an alternative wrapper directinput dll that emulates the current dll but with a direct pipeline to access the keystates (either of which is an inelegant time consumming and risky method of doing this)

oh well will play with it some more to try.

on the possitive side they no longer use directinput for mouse work and instead use the system mouse and htis is pretty simple to work with. so i can do that relativly easilly.

i would appriciate that greatly. in exchange i will package it into a nice little .net class library along with modified send cursor and send keyboard routines making everything in nice one package. figure other people have the same issue and would definatly like this also. if you have any form of repetitive stress syndrom not having to hit a button over and over just because a developer said to is so very nice. <clutches his wrist in agony> my wrist thanks you
