If any strings get changed in the unmanaged code you have to use a StringBuilder object.

Thank you. i'll test that as soon as i can 
this marshalling thing still confuses me a bit. do i have to tell the clr how to marshal the stringbuilder, or should it work when i leave all the marshalAs attributes away?

Hi,
Is the fact that your method return types are different, int vs. void, relevant or is that just a typo in the post.
Alan.

Hi,
yes that's a typo in the post. sorry.
the problem seems now to be solved. the guy who wrote the library said it's because the library uses delay load (what ever that means...).
we have now a version of the dll that works with c#
thanks

Hello,
I am trying to write a service in .NET 1.1 and .NET 2.0 which will catch a event and send it to SQL DB.
The issue is with .NET 1.1 service, the service on .NET 2.0 has no issues and is running without any problems. The service running under .NET 1.1 has a memory leak. I found out that when I use the property "EventLogEntry.Message", .NET 1.1 create for each entry 2 string variables with values "HKLM\System\CurrentControlSet\Services\EventLog". The second string is the same value only on the end of the string is the name of the eventlog file to which a event was written. Does anybody know if this is a bug in the .NET 1.1 framework or do I made a misstake somewere ?
This is a portion my code:
QueryApp = "INSERT INTO " + ComputerName + "_Application" +<br />
" (Category,CategoryString,EventCode,EventType,SourceName,TimeGenerated,TimeWritten,Message,UserName) values " +<br />
"(" + currentEntry.CategoryNumber + ",'" + currentEntry.CategoryNumber.ToString() + "'," + currentEntry.EventID + ",'" + Convert.ToString(currentEntry.EntryType) + "','" + currentEntry.Source +<br />
"','" + currentEntry.TimeGenerated.Month.ToString() + ". " + currentEntry.TimeGenerated.Day.ToString() + ". " + currentEntry.TimeGenerated.Year.ToString() + " " + currentEntry.TimeGenerated.Hour.ToString() + ":" + currentEntry.TimeGenerated.Minute.ToString() + ":" + currentEntry.TimeGenerated.Second.ToString() +<br />
"','" + currentEntry.TimeWritten.Month.ToString() + ". " + currentEntry.TimeWritten.Day.ToString() + ". " + currentEntry.TimeWritten.Year.ToString() + " " + currentEntry.TimeWritten.Hour.ToString() + ":" + currentEntry.TimeWritten.Minute.ToString() + ":" + currentEntry.TimeWritten.Second.ToString() +<br />
"','" + currentEntry.Message.Replace("'", "''") + "','" + currentEntry.UserName + "')";<br />
OleDbCommand commandApp = new OleDbCommand(QueryApp, connection);<br />
commandApp.ExecuteNonQuery();<br />
commandApp.Dispose();<br />
commandApp = null;<br />
QueryApp = null;<br />
if you need to see the whole code just tell me I will pase the whole function.
Thank you
Martin

Hi,
these are two ways to do that.
Convert.ToDecimal(txtPoints.Text.Trim()) <br />
<br />
or <br />
<br />
Decimal.Parse(txtPoints.Text.Trim()) <br />
Thanks,
Sun Rays

What is your question ? I see you are doing a conversion here.
|
|
|
|
|
You don't actually need to convert the value to a decimal to use it in a SqlParameter.Value. The conversion is useful to prove that it is a decimal, but isn't actually needed by the system.
|
|
|
|
|
be sure that you wrote only numbers in the TextBox.
or set it in the try catch to see what is the problem

I don't see your problem, but you can use Decimal.TryParse() to be sure that you have a decimal value in your textbox and avoid errors in your application.
Hope it helps.

it send data to tcp/ip port number, ex 8080, now i want to write socket program to read data from that port. Any body help me? How can i do that?
Thanks,

Create a new socket, bind it to 8080 port and use the Accept or BeginAccept methods (synchronous or asynchronous). When you have accepted a socket use the Receive or BeginReceive methods to read from that socket.

Why do everyone want to have their problems resolved by others with no sweat at all? Search the web and MSDN. I gave you enough hints. MSDN also has a few examples

He's sent you enough information for you to go and do some research on your own on google. That's the way this site works, it's not rentacoder where people give you code in exchange for money.
