Hello everyone!
Okay. I have a game, and it has weapons. I have code like this:
<code>
abstract class Weapon
{
int power;
}
class W_Handgun : Weapon
{
public W_Handgun()
{
power = 40;
}
}
Well, there will be many different types of weapons. So I'd like to save all of the different types in an XML file instead of hard-coding them.
My question is, how do I do that? I know how to read XML files, but how do I convert something like <Handgun><Power>40</Power></Handgun> to the above mentioned class? I'm lost. (And excuse the smiley.)
Thanks in advance!

Look into XML serialization.

Oh, so that's how it's done. I won't use this method because it's an online game, and it'll be easy for people to hack it. But thanks!

At least I hope you won't die at 28

Trust me, I do too.

to store user preference in our application we have an 'hand written' XML file. (as opposed to XmlSerializer written one, which crash sometimes, on some user's computer, for some unknown reason.. but I'm digressing)
In this XML file I store object value, which I convert to string (when writting) and from string (when reading) with a couple of simple function which (should) do a reversible conversion (using TypeConverter) (functions below).
Unfortunately, for some Enum, (namely System.Windows.Forms.Keys) I got a culture dependent string, even though I specify CultureInfo.InvariantCulture as an argument in my ConvertXXX method with the TypeConverter. Even using 'new CultureInfo("en")' do not fix this behavior.
Any tip on how to fix these function (below) so they provide a truly culture independent reversible object=>string=>object mechanism?
===================================================
public static bool TryGetStringValue<T>(object val, out string ret)
{
if (val is string)
{
ret = (string)val;
return true;
}
TypeConverter tc = TypeDescriptor.GetConverter(typeof(T));
if (tc == null)
{
ret = val.ToString();
return false;
}
try
{
ret = tc.ConvertToString(null, CultureInfo.InvariantCulture, val);
return true;
}
catch (ArgumentException) { }
catch (NotSupportedException) { }
ret = val.ToString();
return false;
}
public static bool TryGetTValue<T>(object val, out T tval)
{
if (val is T)
{
tval = (T)val;
return true;
}
TypeConverter tc = TypeDescriptor.GetConverter(typeof(T));
if (tc == null)
{
tval = default(T);
return false;
}
if (!tc.IsValid(val))
{
tval = default(T);
return false;
}
try
{
tval = (T)tc.ConvertFrom(null, CultureInfo.InvariantCulture, val);
return true;
}
catch (ArgumentException) { }
catch (NotSupportedException) { }
tval = default(T);
return false;
}
===================================================

Doing this breaks databinding of controls
<br />
bindingSourceOnWhichControlsAreBound = bindingSourceWithData;<br />
similary like
<br />
dataSetOnWhichControlsAreBound = dataSetWithData;<br />
However when using DataSet you can do:
<br />
dataSetOnWhichControlsAreBound.Clear;<br />
dataSetOnWhichControlsAreBound.Merge(dataSetWithData);<br />
Is there something similar for bindingSource?
Tnx

I have a webservice already written and working.. I was able to pull the wsdl from the .asmx page, but I need to generate an XSD. Is there a way to generate the XSD from wither the wsdl or the existing service code? I'm spent the last hour searching the web and came up w/nothing.
Thanks in advance

Why do you want to generate XSD from WSDL ?
There are many free XSD generators available on net. Just google for it.

Hello
I want to create a form like that you can see in project properties page (Right Click on project name and select properties) in visual studio.net, Is that TabControl or just some buttons with custome effects.
Tank you

It's a custom control, as is much of VS.NET.

Hello,
If u want to get the application just which looks like vs.net then you can try CAB/SCSF from microsoft along with third party controls. and if u r looking for only some design consideration like tabbing, thn i think third party tools will help u in designing in that fashion. One of the third party tool i have used is Infagistics. For tabbing, docking and hide positions(as it is in vs.net) is provided by dockmanager control in Infragistics. There are many third party tools, which u can try as it comes with trial versions.

Tank you freinds
Can you give me a site url about this third party control you mentioned ?
Regards

I am writing a service and I want to load an assembly from within my bin directory where I'm executing from. Assembly.GetExecutingAssembly() returns null. Environment.CurrentDirectory points at the system32 folder. So how the heck to I get where I was loaded from???
Any help would be appreciated.

System.Windows.Forms.Application.ExecutablePath
|
|
|
|

This returns null in a windows service.

If you bothered to read my post instead of jumping in and providing something worthless then you would save from making yourself look like an idiot.
Well how about
System.Windows.Forms.Application.StartupPath
I just found that I use that in one of my services.

I haven't found that to be the case.
Two other methods that may work:
System.Reflection.Assembly.GetCallingAssembly().Location
System.Reflection.Assembly.GetExecutingAssembly().Location
|
|
|
|
|
FYI - I was half asleep while doing all this posting on the service. You kept asking how the ExecutablePath could return null and you are correct it did not return null. Per my original post that is the one call that returned a value: C:\Windows\System32
Obviously that was not useable. The reason I do not get the base folder is because I'm being called by the operating system in my OnStart and OnClose events. The AppDomain finally gave me the correct path since that tracks the base path of the current application domain regardless of the calling application domain.
I believe you asked about why do it in the events in one of your questions. I am managing WCF ServerHost entities which have to be started at OnStart and closed correctly at OnClose or OnShutdown. So I hope this clears all of your confusion regarding what I was experiencing vs. what you experienced.

System.Reflection.Assembly.GetExecutingAssembly().CodeBase;
this will return the path of exe of windows service now to get the directory path parse the string and get the folder path i have dome it for my self u can see it.
////
public string GivePath()
{
string originalPath =System.Reflection.Assembly.GetExecutingAssembly().CodeBase;
int length;
length=originalPath.Length;
string sp=@"/";
char c=System.Convert.ToChar(sp);
string[] splitstring=originalPath.Split(c);
int mylen=splitstring.Length;
string exepro =splitstring[mylen-1];
int exeprolen=exepro.Length;
int reqlength=length-exeprolen;
string truncstring=originalPath.Substring(0,reqlength);
int rellength=truncstring.Length - 8;
string string1=(truncstring.Substring(8,rellength));
//string msg=string.Empty;;
return(string1);
}
just relax

Come to think of it... how can Assembly.GetExecutingAssembly() return null ?! Are you calling from unmanaged code?
|
|
|
|
|
Thank you for the added property I needed.
Now I can give back to you for a faster way to get your path:
string originalPath = System.Reflection.Assembly.GetExecutingAssembly().CodeBase;
string location = originalPath.Substring( 0, originalPath.LastIndexOf(@"\")+1);
