I haven't played much with MAPI; How about attaching certificate[^] with your message so that outlook may identify your mail as a 'safe' one ? Please look at this, and check whether this works for you... [Just a suggestion, and am not sure about this approach]
There are lot of samples on MAPI programmes here[^]; I think you may get some more ideas from there.

Hi,
Our project(client\server application) support redundancy(i.e there 2 running servers,one of them is the root and the other is the secondary,and there are multiple clients connected to each one of the servers.once the root server is down,the secondary becomes the root server and continue to serve the clients from the same location the other server stopped).
The servers uses PING messages between them to realize when a server(which can be the root server) is down(to switch to another root).
In addition,we wrote some kind of watchdog application,which is running on each server,and which is being notified by it's server(keep alive events).
In case that the watchdog didn't get such keepalive event for a predefined period of time(for example - the server is in endless loop) - the watchdog resets it's server in order to let another server to become a root server.
So far so good 
During one of our unit test,we encountered a problem which causes the operating system(Windows XP) of the root server to hangs(note that not only the server application hangs but the computer is not responding).
In such case the watchdog application is not working also,therefor - cannot reset the root server.
You probably ask yourself:
"So whats the problem?
The other server will try to PING to the other root server,and since the PING process will fail,the
other server will become the root server."
Well......you're wrong!!!!! 
For some reason,though the operating system hangs - it still response to PING request.
Now for the questions...
1. We're looking for an API which causes the operating system to hangs (so when we'll fiind a
solution we will be able test it.
2. Is there another way to stop PING handling while the operating system hangs?
3. Is there a built in watchdog mechanism in Windows XP that we can use(or another watchdog
application which runs in a lower level and can reset the computer in case that the operating
system hangs?
Sorry for the (very) lonk post...
With best regards,
Eli

Create a high priority thread with an infinite loop.
This should screw up the system quite bad.

I don't think it wil work since it is a dual-core computer - so only one CPU will be stucked..

You're right. It won't work.
You could try to starve memory using the /burnmemory switch.

Thanks for your reply,I will try that.
In case it is working - is it mean that ,for some reason,the operating system can't get enough physical memory(which is very weird because it is not consistent).
Thanks again,
Eli

That option is just to simulate a machine with less physical memory.

Goto Resource Menu. select toolbar. then select the last icon. this can be modified according to your needs. you just need to drag and drop the menu items to the place where you like.
All the best.

dear all
i have read something in internet how to call c++ .dll, and tried to declare functions in vb 6, but however after i compiled, the error was there:" can't find DLL entry point in xxxx.dll". so how to invoke the c++ member function in one .dll, someone can give me help to realize step by step. thanks a lot in advance.
note: probably one library has several classes, so how can i know which library i can use or how to use it?

Are you exporting the C++ class from the DLL?
If so, the member function names are mangled and exported.
Use a tool like depends.exe that comes along with Visual Studio and look at the exported function name.
Use the same name in your VB code.

thanks a lot. i have read the articles how to export functions names in .dll. but this .dll was created by user. so here i just got .dll. nothing else, so how to export the function names? thanks.
|
|
|
|
|
Do you mean somebody else has created the dll and not you?
If so, the functions have already been exported.
Use Dependency Viewer (depends.exe) and open the dll file.
It will list all the functions that have been exported.
Check the actual name of the function and use that in the VB code.

yes, somebody already created the .dll, i just would like to use it. so how i can use these function directly? also one library has several classes, how to use it properly? thanks..

my code is following:
Private Declare Function DataFormat Lib "icon_vc80_40d.dll" (ByVal cpIpAddress As String, _
ByVal dnsFlag As Boolean) As Boolean
Private Sub Command1_Click()
Dim a As String
Dim b As Boolean
Dim c As String
a = Text1.Text
c = DataFormat(a, True)
Text2.Text = c
End Sub
i used this code to test the .dll, but the error occurred: didn't find .dll file. or couldn't find entry point of .dll. what is problem?
Note: ICON_API icon::DataFormat::DataFormat ( const DataFormat& df,
bool cloneComponents = true
)
Copy constructor.
Parameters:
[in] df DataFormat object to copy.
[in] cloneComponents Specifies if a deep or shallow copy is made.
Thread Safety:
Not thread safe. The data being copied can change at any time.
could you help me to check, is this right? the Note above just showed dataformat() detail.

thanks a lot, i have documentation of .dll, so i know the actual function name, is this right? sorry, i dun know more this point. now i used the code to test one function DataFormat() what i posted in previous reply. so the error occurred: file not found: icon.dll. so what is problem? and also i have several classes in one library, how i can call the functions properly?thanks.

Open the .DLL file in dependency viewer and look at the right hand side pane.
