VB.Net中的SendMessage [英] SendMessage in VB.Net
问题描述
好的，我真的失去了它。我似乎无法绕过
SendMessage函数/方法。我想要做的是将文本/数据
发送到我知道
vb.net应用程序中的句柄的窗口实例。有人可以给我一个很好的代码示例
我需要使用下面的示例数据来创建处理这个代码。
Windows hwnd = 0xB0484
String text =" NM * 14 * ACCTNO * MMDDYY"
我一直在本地和在线帮助中查看它和
在网上搜索全部，我没有得到它。要么我不是b / b
理解它还是遗漏了什么。我现在真的很好
只需要一个好的代码示例。我试图从文本
文件中提取数据并将其以字符串形式发送到另一个应用程序，而无需调用
焦点到窗口。这样我可以在
这个其他程序上运行一批交易。
哦和另外一点信息我正在使用MS VB 2005 Express Edition作为
我的编码环境。
Ok, I am really losing it. I cannot seem to wrap my head around the
SendMessage function/method. What I am trying to do is send text/data
to an instance of a window that I know the handle of from within a
vb.net application. Can someone give me a decent example of the code
I
would need to create to process this using the sample data below.
Windows hwnd = 0xB0484
String text = "NM*14*ACCTNO*MMDDYY"
I have been looking at it both in the local and online help and
searching the web all over and I am not getting it. Either I am not
understanding it right or am missing something. I really right now
just need a good code example. I am trying to pull data from a text
file and send it in strings to another application w/o having to call
focus to the window. This way I can run a batch of transactions on
this other program.
Oh and one other bit of info I am using MS VB 2005 Express Edition as
my coding environment.

我不认为您可以使用SendMessage API发送字符串
消息。该函数只接受消息的整数值和
lparam和wparam。
谢谢，

I don''t think your can use the SendMessage API to send string
messages. The function only accepts integer values for the message and
lparam and wparam.
Thanks,

目标是什么样的窗口？如果它是标准的Windows控件
那么WM_SETTEXT消息可能是您想要的消息。

What kind of window is the target? If it''s a standard Windows control
then the WM_SETTEXT message is probably the one you want.

lparam和wparam都可以是任何指针大小的值，包括
字符串指针等。你实际应该作为参数传递什么
取决于消息。

Both lparam and wparam can be any pointer-sized value, including
string pointers etc. What you actually should pass as arguments
depends on the message.
