Sorry for my late reply.
In this case the application is dedicated to the communication with RSLinx.
Here I attach the code where I cut many non intersting lines of code so it will not run if you try.
Then if yo need I can attach the complete version.
Anyway the lines that i am interested in are highlighted.

I need help on a project which requires me to make use of Expression Blend & WPF to create a software that can:
1. accept & analysis user ink input
2. search library/source/database for similar shape/character
3. display 4 results found
4. display user's choice on textbox
In case I didnt make myself clear, think of it as iPhone's chinese character writing software. Just that in my case im using some image symbols instead of chinese language. Im using Visual Studio 2008 & Expression Blend 2.

You didn't. What exactly are you expecting from us? What code have you written? What are you stuck on? What have you researched? All I see there is a vague set of requirements.

Perhaps you could start by posting this in the Silverlight/WPF forum?
Real men don't use instructions. They are only the manufacturers opinion on how to put the thing together.

hi. friends
small clarification in log4net.
i am new to log4net so any mistake correct me.
i have small program that uses log4net, and i have two appenders like
1.LogFileAppender (writes log to file)
2.ADONetAppender (writes log to DB)
then i have
<root>
<level value="DEBUG" />
<appender-ref ref="LogFileAppender" />
<appender-ref ref="ADONetAppender" />
</root>
when i use this config..my logs written in both
my question are
1. what is that "level value="DEBUG" or INFO " what dose it do and what is the different??
2. i have to write my write debug and info log to my log file and other error,fatal & warning logs to db how can i do that??
any idia of like???
thanks
joe

hi friends
i found the answer
1. it is to set the level like(debu,Info,Warn,Error,fatal)
2.it is possible by setting
(use any one of this code in said the specific appender)
this will set the top level
<threshold value="DEBUG"/>
this will filter the level
<filter type="log4net.Filter.LevelRangeFilter">
<levelMin value="DEBUG" />
<levelMax value="WARN" />
</filter>
Thanks

Hi,
I'm writing a generic DAL layer for my development team because we dont want to give access of connection to the developers. I'm stuck in terms of providing option to handle Transaction oriented queries. Could some one throw light?
So, lets say I've 3 queries which have to be executed under one transaction. Since developer dont have access to Connection they can not create transactions.
Shall I take array of queries and parameters from client and execute within the Transaction Block? Is it a right approach.
Note:- I'm not using ORM hence I can not use Command Patterns also.
Thanks
|

|
|
|
|

The application shouldn't know that multiple queries are required -- it should just call one API method and pass in the data. What happens inside that method might involve a transaction.
PlaceOrder ( Customer , Item )
Begin transaction
Insert order
Insert invoice
Adjust inventory
Commit transaction

I developed a DLL in C#
When I am trying to call it I get:
System.EntryPointNotFoundException: Unable to find an entry point named:
It means that DLL doens't export any methods visible from DLL. Dumpbin doesn't show any methods either:
dumpbin.exe -exports ActiveXTest.dll
Dump of file ActiveXTest.dll
File Type: DLL
Summary
2000 .reloc
2000 .rsrc
2000 .text
What's wrong????
The DLL looks ok.. according to documentation:
namespace Kosmala.Michal.ActiveXTest
public static void setHooks()
{
....
}
Here is how I call it:
namespace IWFHotkeyStarter
{
class Program
{
[DllImport("D:\\work\\iwf\\_ctrl-tab-modless_dlg_testing\\activex\\VSProjects\\AcriveXSourceCode\\bin\\Debug\\ActiveXTest.dll")]
public extern static void setHooks();
static void Main(string[] args)
{
Program p = new Program();
p.run();
}
private void run(){
Console.WriteLine("run<<");
setHooks();
Console.WriteLine("run>>");
}
}
}
Please help

Why are you using a DLLImport and an external function declaration? Why not just add a reference in Visual Studio in your IWFHotkeyStarter by right-clicking the References folder and clicking Add Reference, then browsing for the DLL.
Better yet add both projects to the same solution and use a Project Reference.
Forgive me if you're doing this for a specific reason, but I'm guessing it doesn't work because C# DLLs are not machine code. I've only ever seen DLLImport and extern used for native DLLs, whereas .NET DLLs are in IL, not native code.
Then you will have something like:
using Kosmala.Michal.ActiveXTest;
namespace IWFHotkeyStarter
{
class Program
{
static void Main(string[] args)
{
Program p = new Program();
p.run();
}
private void run(){
Console.WriteLine("run<<");
ActiveXTest.setHooks();
Console.WriteLine("run>>");
}
}
}

you seem confused. A DLL is one of these two:
1.
a bunch of managed code, invisible to DUMPBIN, no need for DllImport; just add reference, use a using statement, and use its public types as if they are part of your EXE itself. the DLL will be copied into your EXE's folder.
2.
a bunch of native code (hence not C#), visible to DUMPBIN; needs DllImport and C# prototypes; add reference is impossible, P/Invoke is required; the DLL gets located through the Windows PATH environment variable.

Hello, I've created a web performance test that logs me in to an internal site. I want to be able to hide the password in the code so I can check it into VSS. I see that creating CodedUI tests seem to encrypt the passwords (i.e. you see what looks to be a hash string instead).
Is there a way to more easily do that with web performance tests?
Thanks in advance for any assistancee.

Hi guys. I am looking for a simple FTP connection. I have an FTP Server running on my local machine. How do I connect to this FTP server using code? All the samples I find refer to a WEB FTP connection. Can somebody direct me to a simple ftp connection that connects to either a local FTP server or connection to an FTP server on a network?
Thanks guys.
Excellence is doing ordinary things extraordinarily well.

I expect FtpWebRequest to work similar to HttpWebRequest, so use the IP address and go ahead. Whether your server is local or on the Internet seems irrelevant to me.

You can use below API's...
Private Declare Function InternetCloseHandle Lib "wininet.dll" (ByVal hInet As Long) As Integer
Private Declare Function InternetConnect Lib "wininet.dll" Alias "InternetConnectA" (ByVal hInternetSession As Long, ByVal sServerName As String, ByVal nServerPort As Integer, ByVal sUserName As String, ByVal sPassword As String, ByVal lService As Long, ByVal lFlags As Long, ByVal lContext As Long) As Long
Private Declare Function InternetOpen Lib "wininet.dll" Alias "InternetOpenA" (ByVal sAgent As String, ByVal lAccessType As Long, ByVal sProxyName As String, ByVal sProxyBypass As String, ByVal lFlags As Long) As Long
Private Declare Function FtpSetCurrentDirectory Lib "wininet.dll" Alias "FtpSetCurrentDirectoryA" (ByVal hFtpSession As Long, ByVal lpszDirectory As String) As Boolean
Private Declare Function FtpGetCurrentDirectory Lib "wininet.dll" Alias "FtpGetCurrentDirectoryA" (ByVal hFtpSession As Long, ByVal lpszCurrentDirectory As String, lpdwCurrentDirectory As Long) As Long
Private Declare Function FtpCreateDirectory Lib "wininet.dll" Alias "FtpCreateDirectoryA" (ByVal hFtpSession As Long, ByVal lpszDirectory As String) As Boolean
Private Declare Function FtpRemoveDirectory Lib "wininet.dll" Alias "FtpRemoveDirectoryA" (ByVal hFtpSession As Long, ByVal lpszDirectory As String) As Boolean
Private Declare Function FtpDeleteFile Lib "wininet.dll" Alias "FtpDeleteFileA" (ByVal hFtpSession As Long, ByVal lpszFileName As String) As Boolean
Private Declare Function FtpRenameFile Lib "wininet.dll" Alias "FtpRenameFileA" (ByVal hFtpSession As Long, ByVal lpszExisting As String, ByVal lpszNew As String) As Boolean
Private Declare Function FtpGetFile Lib "wininet.dll" Alias "FtpGetFileA" (ByVal hConnect As Long, ByVal lpszRemoteFile As String, ByVal lpszNewFile As String, ByVal fFailIfExists As Long, ByVal dwFlagsAndAttributes As Long, ByVal dwFlags As Long, ByRef dwContext As Long) As Boolean
Private Declare Function FtpPutFile Lib "wininet.dll" Alias "FtpPutFileA" (ByVal hConnect As Long, ByVal lpszLocalFile As String, ByVal lpszNewRemoteFile As String, ByVal dwFlags As Long, ByVal dwContext As Long) As Boolean

Thanks for that, however:
1. I'm not the one asking for an FTP solution; you replied to the wrong message.
2. This is the C# forum, no need for VB code.
3. And why would we use P/Invoke when .NET itself has what is required.

Apart from that, what have the Romans ever done for us?

Pete O'Hanlon wrote: what have the Romans ever done for us?
Lots of good things came from the Romans.
They gave us nice roads, connecting major cities, sometimes in remarkably straight lines; admittedly, they haven't been upgraded soon enough (the roads I mean), so now we sometimes have a bit of a jam.
And then they gave you the Hadrian Wall, to protect you against neighboring savages. How can you forget all that?

Under other circumstances, yes, I am, very much so. I do appreciate the classics.
Questions in programming forums are always taken seriously though.
Well, maybe not really always...

Forgot to mention, I also appreciate Cleese's more serious stuff: his business training movies, seminars, etc. Enjoyed a couple of interviews he gave. Quite a guy.
