VP3 is a video codec.
VP3 is the world's most efficient, open source video codec to date. With VP3, there are no platform limitations and developers are not required to pay the restrictive license fees that other open source codecs make mandatory.

Sounds to me like Comm1 is not defined on your form. What makes you feel it should be ?

I would like to get that count SavingCreditCard(9) in some variable? i would be glad if nayone could help me out.

u can do that in JS . Say document.getELementByID("ID") then open the watch window and check for options there . innerhtml or childrens or value can give u ur "SavingCreditCard(9)". U have to debug that in JS.

Dear Subrata,
i got your idea, it really helped me a lot.
My question is, " how to capture the innerhtml values, like [categoryIndex].value"?

I am trying to use a generic class to provide standard data access methods for DataSetS that were created using the wizards. I can't seem to define the TableAdaptor parameter correctly so that the generic recognizes the TableAdaptor Fill() method.
Calling program:
{
GenericIo genericIo =
new GenericIo<
SomeTableAdaptors.SomeTableAdaptor,
SomeDataSet.SomeDataTable>;
SomeTableAdaptors.SomeTableAdaptor tableAdaptor =
new SomeTableAdaptors.SomeTableAdaptor();
SomeDataSet.SomeDataTable dataTable =
new SomeDataSet.SomeDataTable();
genericIo.GetDataTable(tableAdaptor, dataTable);
}
Generic class:
public class GenericIo<t1, t2="">
where T1 : class, new()
where T2 : DataTable, new()
{
public void GetDataTable(T1 tableAdaptor, T2 dataTable)
{
tableAdaptor.Fill(dataTable);
}
}
Compiler error message:
'T1' does not contain a definition for 'Fill'
I have spent many hours trying different things with interfaces, abstract classes, generic constraints, etc. to tell the generic class that T1 does have a Fill method which works on a DataTable, but with no success.
It's either going to be a "no, it can't be done" or the slap-your forehead "Doh". Any guidance will be appreciated.
Thanks,
FShields

Again, with code cleaned up. My apologies.
<br />
Calling program:<br />
{<br />
GenericIo genericIo =<br />
new GenericIo<<br />
SomeTableAdaptors.SomeTableAdaptor,<br />
SomeDataSet.SomeDataTable>;<br />
<br />
SomeTableAdaptors.SomeTableAdaptor tableAdaptor =<br />
new SomeTableAdaptors.SomeTableAdaptor();<br />
SomeDataSet.SomeDataTable dataTable =<br />
new SomeDataSet.SomeDataTable();<br />
<br />
genericIo.GetDataTable(tableAdaptor, dataTable);<br />
}<br />
<br />
Generic class:<br />
public class GenericIo<T1, T2><br />
where T1 : class, new()<br />
where T2 : DataTable, new()<br />
{<br />
public void GetDataTable(T1 tableAdaptor, T2 dataTable)<br />
{<br />
tableAdaptor.Fill(dataTable);<br />
}<br />
}<br />
<br />
Compiler error message:<br />

This short bit of code works well for getting the VolumeSerialNumber using win32_logicaldisk:
ManagementObject disk=new
ManagementObject("win32_logicaldisk.deviceid='C:\'");
this.textBox2.Text = disk.Properties["VolumeSerialNumber"].Value.ToString();
However, I would like to get the manufacturer serial number. I know this is available in win32_PhysicalMedia, but I can't find anything that tells me precisely what the "serial number" is named.
|
|
|
|
|
A little Google goes a long way. All I did was search for "Win32_PhysicalMedia" and wallah[^]!!
It's called, oddly enough, SerialNumber. The problem you're going to run into is that there is nothing that says a manufacturer has to fill this field in. This field may come back empty for any given drive or media.
|
|
|
|
|
Yup. Did the Google thing. I always do before I bother all you hard working folks. Found the same thing you did, tried it, and my little app crashed -- thought maybe I hadn't found the right name after all.
I suppose, based on what you say, it might mean there is no serial for my harddrive.
Bummer.
|
|
|
|
|
The last time I did this, only 2 out of 6 of my drives filled in the Serial Number field...
|
|
|
|
|
That's too bad. It would sure make my life easier if it was a standard all manufacturers followed.
Thanks for the feedback.

i have written a c++ application now i want to override virtual event handlers in the c++ app with c#.
also i want to compile the c++ app - or part of it- as a dll that i can reference in c#. but i keep on getting an error saying it's not a com object...
problem
1. what type of project do i need to create for c++ to be accesible in c#
2. how do i override an event handler.
or
how do i call a c# method from c++ (instead of overriding the event handler. i'll call a c# method
in a different dll)
rather have something you don't need, than need something you don't have
|
|
|
|
|
ok i compiled the c++ with /clr now c# adds the reference

got it working with dllimport but cannot get it to call a c++ method
c#code :
<br />
using System;<br />
using System.Collections.Generic;<br />
using System.Text;<br />
using System.Runtime.InteropServices;<br />
<br />
<br />
namespace ConsoleApplication2<br />
{<br />
class Program<br />
{<br />
static void Main(string[] args)<br />
{<br />
int mine = tester();<br />
Console.WriteLine(mine);<br />
<br />
}<br />
<br />
[DllImport("touchlib.dll", EntryPoint = "tester",<br />
ExactSpelling = false, CallingConvention = CallingConvention.Cdecl)]<br />
static extern int tester();<br />
}<br />
<br />
<br />
}<br />
c++ code
<br />
int Touchable::tester()<br />
{<br />
return 5;<br />
}

Hi,
DllImport is used to call native code such as Win32 functions.
if your C++ dll is .NET code, just call the C++ class as if it were C#.
|
|
|
|
|
should i add a using <dllname.dll> ?
and for functions in a class do i need to call Class::function()?

donsolms wrote: should i add a using ?
yes
donsolms wrote: for functions in a class do i need to call Class::function()?
no
calling any CLR compliant language obeys the rules of the calling language, hence
in C# you need a using statement, and call as class.method(args) or object.method(args).
|
|
|
|

i can't get the using to work. i have the c++ dll in a namespace named touchlib and then a class named Touchable.
<br />
using touchlib;<br />
doesn't work, i have added a reference to the dll. a i missing something, maybe in the compiling of the dll? how can i be sure that the dll is managed c++? what type of vc++ project is managed c++?

Hi,
I dont remember the details for C++, but you did build the C++ dll, didnt you ?
so you know it is/isnt managed code.
if you were able to add a reference to it in your C# app, it must be managed code.
now Intellisense should show the available classes (C# and managed C++).
