Reposting here since I didn't get any responce in the c# forum.
My app's written in c#, but the error's being generated by a win32 api call. I'm using the following 3 api calls as demonstrated in the msdn article to monitor changes being made to a folder over samba (FileSystemWatcher won't do this). In my test app the water class works perfectly. When I use my watcher class in my main app everything is fine with one copy running. With two copies though, FindNextChangeNotification returns false and generates errorcode 0x64006e as returned by Marshal.GetLastWin32Error(). Win32Exception.Message describes this as an uknown error, and no error codes with this large a value are listed in msdn, or winError.h. Looking at the code between my main app and my tester I'm not seeing any meaningful differences, and with an unknown error I don't know wehre to be looking. The biggest difference between the two is that when a change occurs my tester just throws up a message box, while my main app reloads all the files in the folder. (There're only a handful so the performance hit from loading everything isn't enough to justify the extra work needed to ID which file was modified).

you can't use the .Net framework in VC 6.0. You will have to use CString or the C-Runtime Library funcitons.

Thx Willy, but which C-Runtime Library funcitons i have to use instead of Timstart()?
|
|
|
|

The easiest way is to use CString LeftTrim, but if you can't use CString. You might be able to use StrTrim, but it will remove the chars from the left and right, so if that will not work for you, you will have to loop through the string.

FRIEND DONT INCLUDE DLL FILE
dll project generates two important files
1).dll
2) .lib
A)copy these both files in your main project debug dirctory
B)copy the header file of the all\required classes used in DLL PROJECT in to main project directory.
Include these header files wherever it does not identify class
if required.
C)IN MAIN PROJECT Goto Menu Project - > settings open the link tab inthat
Object\link modules type the name of lib file with extension
D) In addition copy the dll and lib in your main project folder also remember earlier i asked to copy in debug folder where your exe gets generated now i am asking just for safety.
REMEMBER DLL IS NOT HEADER FILE TO INCLUDE
still problem contact me

A program's message loop reads any pending message from the message queue and then dispatches that message back to Windows, which then calls your program's window procedure with that message as a parameter. Without MFC, you are responsible for both the message loop and the window procedure. MFC handles this for you.

I got this request from my boss.. :
Are you familiar with writing “message pumps”?
This is where you would “push” and “pop” off of dynamic arrays to control threading of commands to API’s.
Multiple threads can “push” messages onto the message stack using a single locking mutex and one single thread “pops” the messages off of the message stack and sends them to the API (using the same locking mutex).
--------------------------------------
what he means actually?.. yeaa we can send messages to the queue.. using sendmessage,postmessage..but should i go for win32 api ? where these messages would be processed by the wndproc ? but whatz the need for mutex here?

I'm curious why you are being asked to do something that Windows already does and does well. If you use SendMessage(), control does not return until after the window procedure has processed the message. If you use PostMessage(), control returns immediately.

i guess he's talking in context with the user defined messages.. i'll get back to you after getting a clear requirement.
thanks.

In terms of how the message is entered into the message queue (SendMessage() vs. PostMessage()), there is no difference between a user-defined message and a system message. If the default window procedure sees a message it does not care about (e.g., user-defined message), the message is ignored. If your window procedure sees a message it does not care about (e.g., system message), the message is ignored.

Collaboration Data Objects is an object library that exposes the interfaces of MAPI. Because it is based on COM, it is language independent. To collaborate means to work together, especially in a joint intellectual effort, much like Outlook does.

Hello,
I dont know, how to implementate a registration script
"hInstance needs to be the module / instance handle
of the module that contains your server registration
script (resource ID 102) .."
the server registration script is importand to
register my OPC Server.
RegisterServer()
HRESULT RegisterServer(void)
Return Values S_OK upon success, otherwise the result code
returned from the ATL registrar component.
The success of this operation is dependent on the application
including a registry script resource as part of its EXE.
The resource ID MUST be 102. An example resource script
is shown below:
HKCR
{
NDI.SimulationSvr.1 = s 'NDI Simulation Server'
{ CLSID = s '{1E52DE00-FA5E-11d2-91C6-F8E932000000}'
...
Best regards

I'm converting a project from a VC++ ActiveX control to a C++ .net control.
The mouse button handling will change mode so that if left button is pressed on thing happens, right button does something else, and both buttons does another thing. This works OK but after having pressed both mouse buttons and then releasing one of the buttons the control loses capture (Control::Capture returns false). Under ActiveX/COM it didn't behave like this.
I've tried tracking the capture state during the mousedown and mouseup event handlers but still can't see what's going wrong.
Anybody got any ideas?
Thanks,
Dan

The method that the above site provides may be useful to send e_mail on the old smtp protocol servers. This kind of servers dont need the user name and password when they are connected to send e_mail. But now most of the e_mail servers update e-mail system for security and against rubbish e-mails.They ask users to provide user names and passwords to be connected.
to send mail,you should follow:
1、use socket to connect to the smtp server .
2、send "ehlo the smtp server \r\n" to the smtp server . you will receive the "250" from the smtp server,which stands for ok.
3、send "auth login \r\n" .then will receive the "334" from the smtp server.
4、send "your user name\r\n" which is encoded by the base64 arithmetic. you will receive the "334" .
5、send "your password"which encoded by the base64 arithmetic. you will receive the "235" that stands for ok.
6、so much to write.then follow the above site to continue.
