How do I load an Assembly dynamically in a NEW appdomain?
The assembly is in bytes[] array.

You should look for articles that deals with reflection and plugins.
YOu should be able to get the code you need from there.
I have a little plugin system on my page too (oldow it does not load an assembly into a new appdomain): http://cwizo.slogamedev.net/index.php?i=showcase&s=programs

_________________________________________________________
The Assembly that I need to load:
_________________________________________________________
namespace WindowsApplication4
{
public class TestDll : MarshalByRefObject,interfaces.Test
{
public string HelloWorld()
{
return "Hello World";
}
}
}
_________________________________________________________
interfaces.Test is in a seprate dll. code is as below:
_________________________________________________________
namespace interfaces
{
public interface Test
{
string HelloWorld();
}
}
_________________________________________________________
The code that I am using to load:
_________________________________________________________
AppDomain currentDomain = AppDomain.CreateDomain("mydomain1");
currentDomain.AssemblyResolve += new ResolveEventHandler(MyResolver);
domain.CreateInstance("TestAssembly, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null", "WindowsApplication4.TestDll");
static Assembly MyResolver(object sender, ResolveEventArgs args)
{
Assembly assembly;
AppDomain domain = (AppDomain)sender;
// Actually the assembly in bytes will come from database so temporarily loading it as below:
byte[] rawAssembly = loadFile("d:\\TestAssembly.dll");
assembly = domain.Load(rawAssembly);
return assembly;
}
I DO NOT FACE ANY PROBLEM IN LOADING THE ASSEMBLY WHEN IT IS NOT IMPLEMENTING THE INTERFACE. IT WORKS FINE IN THAT CASE.

I am guessing but I think that you should add refrence to the Interface dll in your TestDLL
but you should really post some error or something.

I get the following error:
{"Could not load file or assembly 'TestAssembly, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.":"TestAssembly, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"}
reference of interface.dll is added in Testdll. Testdll can not be compiled without the reference

Just you would normally, but you need to call it from within that AppDomain.

I have set up the tab order of the textboxes on windows form.
When I tab out of one textbox to go to the next one, I would like to do a calculation.
i.e. textbox1 has a value of 3
tabbing out of textbox1 I would like to go to textbox 2 and have a figure in it
i.e. textbox2 = 5
How is this tabbing done please?
Thanks

Do your calculations in the LostFocus or Leave event of your textbox.

First decide what will you use.
DirectX or OpenGL?

The problem with my program right now is that it will be ran on pIII-400's. When I switch language from english to chinese in my program, the program blanks out all the pictures, and takes a while to switch language. (ie, It looks like its frozen for a bit)
Is there any way to make it so that it finishes changing the stuff in the background first, and then update the visual, so that it doesnt loo likek its frozen? It seems like its busy updating stuff in the background thats why the UI doesnt get the response time.

All the GUI proccessing is done in one thread.
If you have any operations that are not realeted to the GUI, then you can create a new thread and do the proccessiin there.
That way the GUI will function normally.

how to execute a text file, which contains sql script of a database.
I need to execute this file in my code.. i tried this function:
private void ExecSqlFileProcess(String fileName)
{
if (! File.Exists(fileName))
{
MessageBox.Show ("Specified .SQL File Not Found.","Net Fare Database Upgrade Tool",MessageBoxButtons.OK);
return;
}
using (StreamReader sr = new StreamReader(fileName))
{
String line,line1;
String sqlLine= "" ;
while ((line = sr.ReadLine()) != null)
{
line1 = line.Trim();
int compareResult = String.Compare(line1, "GO", true, CultureInfo.InvariantCulture);
if(compareResult != 0)
sqlLine += line + Environment.NewLine ;
//sqlLine += line + c.ToString() ;
else
{
if(sqlLine != "")
{
try
{
int i = SqlHelper.ExecuteNonQuery(connectionString,CommandType.Text,"USE "+DatabaseName+" "+sqlLine);
}
catch(Exception Ex)
{
MessageBox.Show (Ex.Message.ToString(),"Net Fare Database Upgrade Tool",MessageBoxButtons.OK ,MessageBoxIcon.Error );;
sqlLine = "";
}
}
sqlLine = "";
}
}//While
}//Using
}
but i got the following errors for all stored procedure scripts..but it dropped the stored procedure..it only did not create it..following error comes:
'Create Procedure' must be first statement in the query batch.
Must declare variable @IATACodeName, @IATADescription..etc..

I am having a problem with this method:
private void UniversalRegEx(string szMyRegEx, string szWhatFor)
{
//The universal RegEx
//Set it (Query, What it will put as a heading)
Regex rxFind = new Regex((szMyRegEx), RegexOptions.IgnoreCase);
MatchCollection matches = rxFind.Matches(szTibiaProfile);
foreach(Match m in matches)
{
string szTemp = szWhatFor + ": {0}", m.Groups["mmatch"];
WriteLookup(szTemp);
}
return;
}
See the problem? It says this is wrong:
string szTemp = szWhatFor + ": {0}", m.Groups["mmatch"];
Thanks for the help.
Example of passed data:
//Get Character Name
UniversalRegEx(">Name <mmatch>[a-z]+)", "Name");
|
|
|
|
|
replace this line
string szTemp = szWhatFor + ": {0}", m.Groups["mmatch"];
with
string szTemp = szWhatFor + ": "+ m.Groups["mmatch"];

That works now, thanks. But what did I do wrong with the way I set it up? In my console app that works.
|
|

In your console app, this is a valid function call:
Console.WriteLine("Here is my string: {0}", myString);
but without this function:
"Here is my string: {0}", myString; //this is not valid syntax.
If you want to define a string like this, use the String.Format function.
String.Format("Here is my string: {0}", myString); //this is valid
Otherwise, use proper syntax:
"Here is my string: " + myString; //this is valid syntax.

Hi,
I need to display some DirectDraw surface (.dds) files in my application (Not my choice, that's the stuff I've been given). Is this possible without using DirectX? If not, can I somehow use DirectX to load the dds into a PictureBox?
Thanks.

You can initialize DirectX to draw into any control you want.
If you are looking for a quick way to do some DX you should look at this: http://www.3dlevel.com/gamedev/news.php
this is a game engine build with VB.NET and uses managed DX. Very simple, takes only a few lines to show a sprite or whatever...
So if you don't want to learn all the DX stuff this is defenitly the way to go.
