Re: .NET 4.x --- WPF team is not going to take away System.Collections like they do with Silverlight right?!

look at example class Person design, you don't get to know property type until runtime.

I still don't follow what you're trying to say. If you're saying that you can't make Person generic, I don't see why not.

Silverlight is a subset of .NET and does not have all of the features of it, such as the example you provided. All .NET framework increments are designed to be backwards/forward compatible so that no applications are broken with each release.

i understand silverlight is a subset - however just that when people interpret taking System.Collection out (use only Generics) saying it's "obsolete" "deprecated" makes me bit nervous - we do need this facility just as much as Generics because there're times we don't know type until runtime.

You always have the option of using object -- List<object>

"obsolete" and "deprecated" just means that better alternatives are available (*usually*). The classes are still technically useable, but it is just no longer recommended. You can even still use the original Menu class from .NET 1.0 lol.

And yes, for generic collections, you can use Collection<object> without having any problems, but I see that someone else already suggested that.

DriveInfoEx.dll is not working on client PC

17-Feb-09 22:59

hey

Some guy just gave me a suggestion

class Person
{
Dictionary<string,> Properties;
}

While I don't know property type in compile time, I do know they all derived from Object!

So problem solved! Thanks!

You need to ship the DriveInfoEx.dll file with your application for it to work, and it must be in the same folder as the app (IIRC).

Try installing the latest version of the .NET Framework[^] on the client pc to see if that helps.

Hi all,

I got the following error on my application.

the Current thread must be set to single thread apartment (STA) mode before<br />
OLE calls can be made. Ensure that your Main function has STAThreadAttribute<br />
marked on it. This exception is only raised if a debugger is attached to the<br />
process.

Can someone comment on this, what means is.

Thanks a lot.

I appreciate your help all the time...

Try adding [STAThread] just above your Main function, like this:

[STAThread]
static void Main(string[] args)

Hi All.
I have Data grid and bind it to a bindingSource object.I set bindingsource DataSource property to a list of class A.
my list:

 List<da.viwpurchasedetail> lstPVirtualDetails = new List<cooky.da.viwpurchasedetail>();
my Bindingsource:bndDetails
   bndDetails.DataSource = lstPVirtualDetails;</cooky.da.viwpurchasedetail></da.viwpurchasedetail>
my grid:dgDetails
 dgDetails.DataSource = bndDetails;

Then I add some A object to list But Gridview don't display any thing Confused | :confused:

DA.viwPurchaseDetail details = new Cooky.DA.viwPurchaseDetail();

          details.discount = discount;
          details.name = lblProduct.Text;
          details.price = price;
          details.quantity = quantity;
          details.id = CurProduct.id;

          lstPVirtualDetails.Add(details);

But my grid don't display any thing.
What's problem?

How to run EXE by Coding in C#

am 200916-Feb-09 20:05

16-Feb-09 20:05

Hi All,

I want to run Exe using C# code. I have myprogram.exe and i want to run it
by passing "myfile.cs" parameter. I test it on commant promt but when i run it by following code EXE is not execute. Code is as

Process proc = new Process();
proc.StartInfo.FileName = @"E:\test\testEXE\myprogram.exe";

proc.StartInfo.RedirectStandardOutput = true;
proc.StartInfo.UseShellExecute = false;

procAStoCS.StartInfo.UseShellExecute = false;
procAStoCS.StartInfo.CreateNoWindow = true;

string str = @"E:\test\testEXE\myfile.cs";

procAStoCS.StartInfo.Arguments = str ;

procAStoCS.Start(); // Start

procAStoCS.WaitForExit();

i develop myprogram.exe in C#. Is there any special setting for Exe develop in C#, because if i use above code for running some other exe i.e. Notepad then it is working fine.

Thanks in Advance

does 'myprogram.exe' run in taskmanager?
is 'mygprogram' designed to take parameters?

hi
myProgram.exe is not running in Taskmanager. When i test this exe on command prompt by passing parameter, it runs as expected. Myprogram.exe is designed to take parameters.

Thanks

what is procAStoCS ??

Edit - Assuming there was some typo in the code you shared. What happenes or doesnt happen when you run this code i.e. the exe doesn't fire or the parameter is not passed to it ? what does proc.Start return ?

Process proc = new Process();
proc.StartInfo.FileName = @"E:\test\testEXE\myprogram.exe";

proc.StartInfo.RedirectStandardOutput = true;

proc.StartInfo.CreateNoWindow = true;

string str = @"E:\test\testEXE\myfile.cs";

proc.StartInfo.Arguments = str ;

proc.Start(); // Start

proc.WaitForExit();
this is code i m using to run myprogram.exe by passing myfile.cs argument.

Thanks

proc.Start returns a bool whether the invoke was success/failure. what is it in your case

bool result = proc.Start();

Is the process not being started or is your paramter not being passed ?
