How to send network messages

[Jan B.]

Hi,

i'm searching a way how to send a message through
the messenger service. i found the corresponding
function in the "netapi32.dll". Now i got problems
while i try to use it.

Can anybody help me and say me how to do it or another
way to realize this feature?

Thx

The API is NetMessasgeBufferSender, and should be declared like this:

(Replace <Scope> with Public/Private/Friend)

<WatchForWrapping>

<Scope> Declare Function NetMessageBufferSend Lib "NETAPI32.DLL" (ByVal
strServer As String, ByVal strTitle As String, ByVal strFrom As String,
ByVal strBuf As String, ByVal intLength As Integer) As Integer

</WatchForWrapping>

Then can be called like this:

Dim strMsg As String = "This is a network message"
NetMessageBufferSend("Server", "SendToComputer", "SentFromComputer", strMsg,
strMsg.Length)

Error 123 is ERROR_INVALID_NAME, so yes, it may be because the \\ are
required, or you have accidentally misspelt a computer name.

Hi,

i tried nearly all types of names and used all possible
configurations. So i think theres another problem than
only the wrong name. i can use the name when i try it with
net send ... So i don't know.....

Ciao, Thx
Jan

Hi ,

thanks for your tip. Right now i use the shell command like
you told me. but since the program might run on machines
where the net command has been removed i wanted to use
some other method.
Your mailslot info is quite interesting but i need to
address the users instead of the machine.

Thx
Jan

Hi Jan,

You don't need to call any function in "netapi32.dll" if you only need tosend a message through the messenger service. The simplest way is to callShell in VB. You can use the following code to do this.

Shell("net send <destination computer> hello")

You could also use mailslot to programmatically send message. Just send themessage to "\\.\mailslot\messngr"

The following link may help:

If there's anything unclear, please feel free to reply to the post.

That is no topic for this newsgroup, to run a VB.net language application
you need to have installed the net framework on the computer running it.

@first: Hello,

for sure i got the framwork installed. i don't understand
why youre saying this is the wrong newsgroup since
i asked how to send a network message for the messenger
service out of a vb .net app.

feel free to explain yourself.

Jan

Jan,
Maybe I did understand this wrong

thanks for your tip. Right now i use the shell command likeyou told me. but since the program might run on machines
where the net command has been removed i wanted to use
some other method.

I thought that you did mean the .Net framework
