SendControl(int PNO, int SendType,HWND hwnd) &
功能：发送数据 &
参数：PNO:屏号 &
SendType:发送模式1为普通 2为SD卡发送 &
Hwnd:窗口句柄 &
返回值： &
1：发送成功 &
2：通讯失败&
3：发送过程中出错我在模块这样定义的DLL:'7发送数据Public Declare Function SendControl Lib &ListenPlayDll.dll& (ByVal pno As Long, ByVal SendType As Long, ByVal hwnd As Long) As Long程序是这样掉用的:Private Sub Command3_Click()StartSend

如果愿意，你可以把DLL和SDK发到资源里面让大家研究一下。光这样猜测，太有难度。
------解决方案--------------------
要返回值而已,你这样用不就有返回值,i=SendControl( 1, 1, 0 '屏号 发送模式1为普通 2为SD卡发送 Hwnd:窗口句),i就是返回值啊!

J it only takes a minute:
Could anyone please help how do I solve this error:
Native code library failed to load.
java.lang.UnsatisfiedLinkError: no ts-jni in java.library.path
I am using IDEA IDE as a first time, and have been using Resin_4.0.37 as a server to test my work.
As soon as I start my lcoal server in debug mode it stays for approximately 1-2 mins and then suddenly it drops down and get disconnected by giving me the above error.
I have set my Windows environmenta and have also did the following in my IDE intelliJ:
FILE-&Project Structure-&set Global Libraries-&a. Java path and b. Resin library path.
Can any one please suggest me, what am I doing wrong and how do I set native library in intelliJ IDEA to solve the mentioned error.
Any help would be appreciated. Also do correct me if I am doing something wrong.

If you run your program from IntelliJ then you can set the java.library.path in the VM options input field in the Run/Debug Configurations dialog.

环境：VS2012+WIN8 64
类型：C++编写的WDM驱动程序
测试：VM WIN7
用途：主要用于驱动程序中得到WIN32 API地址，也可得到自定义的DLL中的函数导出地址，记录内核文件相关操作以便以后查看。
说明：此段代码来源于网络，经修改调试而成。

1. 开发中经常会使用到VC的一个工具 Dependency Walker用depends.exe打开dll，文件名前有64标示的即为64位。
但是这个方式不是万能的，只能简单判断。很多都判断不出来。比如64位系统下
C:\Windows\System32\msvcrt.dll
2. 使用visual studio开发工具命令dumpbin一般位于vs安装目录bin子目录下，如C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\amd64&dumpbin.exe使用命令 dumpbin /headers yourdll.dll |find "machine"
machine (x64) 标示该dll为 64位。否则为x86下面(PE32+) 也是标示该dll为 64位。否则为PE32
