hello

What are the common issues when you try to port your application to run on 64 bit windows? Is this pretty the only/first issue you'd run into?

Thanks

I found that marking my app as being 32 bit forced compatibility mode in 64 bit, which was all I ever needed to do ( of course, this means it runs as 32 bit ).

anyone who can give me one simple but good example to demonstrate that application domain has to be used.

because I found most examples for application domain can not demonstrate clearly that the necessity of application domain.

thanks.

thanks.

but I still can not find some concret examples. It seems to me most people did not use it often.

this may be the reason that it is hard to find some good practical examples.

I use an App Domain to load config files into a process and associate it with a DLL. I blogged about a variant of my code here[^].

Every .NET application will have an application domain associated with it and it will be created automatically. Creating your own application domains helps you when you are dealing with plugin kind of architecture. Each plugin can be loaded on a new application domain and it can work isolated.

If you are familiar with NUnit, they use a new application domain to load the assemblies specified by the user. This will help them to isolate user code execution and proper resource and memory cleanups. When an application domain is unloaded, all the memory associated with it will be cleared.

Hope that makes it clear Smile | :)

Deserialization Issue

Hello Guys,
I have an issue with Deserialization. I have 2 Projects and I want to extport data to a binary file (serialize) in the first Project, and i want to read that date using the second application Deserialize.
The first Aplication will be given to hte end user, and will generate a Binary file that i want to read using the Admin application (the second one).
When i try to deserialize i receive this error:
"Unable to find assembly 'Application Timing', Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'."
I think i know the cause of the issue. The binary formatter puts the Application name,version and info in the file when it serilizes it, but i don't know how to bypass this.

Any suggestions? Confused | :confused:

Kind regards,
Alex

There are two options:
1. Put the class definition in a separate assembly and deploy it in both applications
2. Use SerializationBinder. Here is an example: Draw with Mouse[^]

Hi all,

Using C#, is it possible to handshake a certain remote port using only the first two steps (SYN -> SYN-ACK), and then cut-off the connection without the final third step (ACK)?

The requirement is NOT to send the ACK, and as far as I understand, the Connect method of the Socket, handles all the 3 steps handshake automaticaly.
So is there a way to, somehow, stop after the first two steps?

Thanks in advance,
Danny

I guess following code would work for you:

        {
            for (int i = 0; i < this.webBrowser1.Document.Images.Count; i++)
            {
                this.webBrowser1.Document.Images[i].Style = "display:none;";
            }
        }

You're making a key-logger, therefore you're unlikely to get any help here.

If at first you don't succeed, you're not Chuck Norris.

Hi Experts
I had made setup on my PC.I wanted to run that setup on my clients PC without making changes in connectionstring and without attaching to SQL SERVER 2005...
I wanted that my log and mdf files should automatically take path of database.I have kept both the files in my debug folder.

Would better if you can provide a bit more. Anyway, why you have kept the files in Debug folder.When you prepare your final build, it should be in release mode which you can consider as your application directory.So try to code keeping relative path in mind and which you can store in your config file.
Same is applicable for your connection string which you should be keeping in your config file.Please visit this link.[^].

Iam Trying to Insert Array values in the database , but first value get inserted but when my loop increments and try to insert the second value iam getting the Error "exSql = {"The variable name '@BezierCusp' has already been declared. Variable names must be unique within a query batch or stored procedure."}Please help me out where iam wrong

SqlConnection con = new SqlConnection();
con.ConnectionString = "Data Source=localhost;Initial Catalog=InkDb;Integrated Security=True;
Persist Security Info=True;Packet Size=4096";
string qry = "Insert into beziertable values(@strokeIndex,@cuspIndex,@BezierCusp)";
SqlCommand sqlInsertCmd = new SqlCommand(qry, con);
sqlInsertCmd.CommandText = qry;
sqlInsertCmd.CommandType = CommandType.Text;
int count;
int i;
sqlInsertCmd.Parameters.AddWithValue("@strokeIndex", mInkoverlay.Ink.Strokes.IndexOf(stroke));
int cus;
cus = Convert.ToInt16(stroke.BezierCusps.GetValue(0));
sqlInsertCmd.Parameters.AddWithValue("@cuspIndex", cus);
//Using loop to get the all stroke.GetPoint , it will return Array(2dimension) , i want to add all values of array
//In the Database In the parameter Bezier Cusp ,but it show me the error that"exSql = {"The variable name '@BezierCusp' has already been declared. Variable names must be unique within a query batch or stored procedure."}
for (i = 0; i <= 100; i = i + 1)
{
val=stroke.GetPoint(i).X;
sqlInsertCmd.Parameters.AddWithValue("@BezierCusp",val);
sqlInsertCmd.Connection = con;
SqlDataAdapter sqlDataAdapter3 = new SqlDataAdapter();
sqlDataAdapter3.InsertCommand = sqlInsertCmd;
con.Open();
sqlInsertCmd.ExecuteNonQuery();
con.Close();
}
Iam unable to find out the Reason my table structure should be like this after Inserting
Stroke Index Cusp Index Bezeir Cusp
0 0 1st value of array(X componet)
1 1 2nd value of Array
like this it should insert the Record in this manner
tell me there any wrong logic iam using to insert the array values in database
