Yes, if your new to this i would start simple. For my final project at uni i had to wrap an old C++ header file to .net. It was very tricky, but not imposible!
First have a google at wrapping C++ into .net, and get round the concept of IJW (it just works) that try a basic C++ concole app first in MC++ to wrap it into .net!
your first example wants to be simple, then move on to pinning parameters, this is a bit complex.
good luck

I heard on the MS parnetship sites that the VS2005 service pack 1 was shipping next week. But, the public potion of MS says Q3.
Does anyone know the truth?
I heard it has edit and continue for c#, so I can't wait.

1 line of code equals many bugs. So don't write any!!

What do you mean with "Edit and Continue"? I assumed it just meant you could change the code from the debugger and continue execution of the modified code directly. But since this is already available for C# in VS2005 without any service pack, you must be referring to something else?
|

|

It doesn't work for me. Is there a setting?
It barks at me if I try and continue. On the partnership sites it says ts not available till q03.

..its defintely in. I use it all the time. Had an idea that the service pack isn't out for quite a while yet, which is a pity as there's quite a few issues which need addressing.
Tools->Options, Debugging->Edit and Continue->Enable Edit and Continue.

I don't have the Debugging section in Tools->Options.
Although I have the VB setup because I like the VB shortcuts better. Is that an Issue?

As far as I'm aware it's due in q3. However, VS 2003 SP1 should be due any time now. Maybe that's what the confusion is?

We have used one listbox in windows form and we bind it with datasource from database.
Listbox allows multiple selected.
How can we retrive value of selected items from the list box??
we tried following thing
for(int i=0;i
|
|
|
|
|
What do you think is the selected value? 
You filled the list with a DataView (which is a set of DataRowViews), so SelectedItems[n] returns the selected DataRowView.
I hope you have already tried that:
MessageBox.Show( ((DataRowView)lstEducation.SelectedItems[i])[0].ToString() )

Along with the first post you can also set the DisplayMember and ValueMemeber to the column names you would like to display and key off of.

i made a webform in asp.net and i want to print that web form design by clicking the button in the webfrom.anybody know how can i do it?
thank you so much
|
|

|

Sure you can print it!  Attach to button this client script "window.print()" it's all you need to do. Also you can put two functions on your page
function window.onbeforeprint()
{
//Make you changes before printing, like
//hiding unnecessary while printing elements
}
and
function window.onafterprint()
{
//Restore previous state after printing
}

IS it for visual basic ,asp.net webform?
|
|
|
|
|
No, it's Javascript. If you would use ASP.NET to print anything, it would be printed on a printer connected to the server.

I am using Asyncallback in .net CF development. I added the callback in a button_click event, but as I run the program, it is fine to deploy the program, but as I click the button, error occured. The message is 'An unhandled exception of type 'System.NotSupportedException' occurred in System.Windows.Forms.dll', and it stopped at 'application.run(new form())' I used the begininvoke to start the callback, and endinvoke to get the result. Thanks for your help.

For size and performance reasons, the .NET Compact Framework supports only a subset of the .NET Framework. Control.BeginInvoke() and Control.EndInvoke() are two of those methods not supported by the .NET CF. You will need to use Control.Invoke() or some other asynchronous mechanism instead.

Thanks for your reply. So you mean that in .net cf, BeginInvoke() and EndInvoke are not supported. But as I opened a new thread, I can use BeginInvoke() and EndInvoke(). Here comes the source code.
button_click(....)
{
...
Thread myThread = new Thread(new ThreadStart(myThreadMethod));
myThread.Start;
}
myThreadMethod()
{
this.BeginInvoke(delegate, object)
}
I posted the detail of my question with some source code below, and thanks for your help.
I am using Asyncallback in .net CF development in a button_click event. There is no problem when I deploy the program, but as I click the button, error occured. The message is 'An unhandled exception of type 'System.NotSupportedException' occurred in System.Windows.Forms.dll', and it stopped at 'application.run(new form())' I used the begininvoke to start the callback, and endinvoke to get the result. I used ppc 2003 emulator, and vs2005. Thanks for your help.
Here comes part of my code:
private delegate int CalcDelegate(int input1, int input2, ref string strResult);
CalcDelegate mDeleg;
private void button1_Click(object sender, System.EventArgs e)
{
mDeleg = new CalcDelegate(Calc);
int input1 = Convert.ToInt16(textBox1.Text);
int input2 = Convert.ToInt16(textBox2.Text);
string strResult = null; // dummy parameter
AsyncCallback cb = new AsyncCallback(CalcCallback);
IAsyncResult ar = mDeleg.BeginInvoke(input1, input2, ref strResult, cb, null);
Thread.Sleep(1000);
}
private void CalcCallback(IAsyncResult ar)
{
string result=null;
int output = mDeleg.EndInvoke(ref result, ar);
textBox3.Text = output.ToString();
}
if I could not use BeginInvoke() and EndInvoke(), how can I change this code? Thanks.

I think you're second block of code is ok. The BeginInvoke() and EndInvoke() methods of delegates are supported by the .NET Compact Framework, as far as I can tell. (I believe the BeginInvoke() and EndInvoke() methods are implicitly created by the compiler, for each type of delegate declared, and not really a part of the Delegate class API itself.) It is only Control.BeginInvoke() and Control.EndInvoke() which are not supported (as used in your first block of code).

Hi,
Is it possible to integrate the module developed in c#.net in vc++.net?
If yes, then please let me know how it is done and using what?

Do you mean to say, going for C# to VC++ or the other way round?
The inteoperatability of .net for C++ is the IJW switch, this means visual studio .net will complile legacy C++ code, but the other way, how would an older version of visual studio know how to complile .net code?
you would only be able to upgrade code, not the other way round!
thanks

Can anyone tell me how to make a .Net Control, that performs some or the other function when added in MS-Word, or Excel.

I don't expect that your question, as currently stated, will receive a helpful answer. You'll need to elaborate.
