Is there any way that I can let the user enter a new record through a form and then add that record dynamically to a combobox (while user types), and give a new primary key to that new record?
Thanks

Well to give the user the ability to add to the combobox:
Textbox tbxText=new Textbox
tbxText.tex='insert user input; could be already created if on the form
Combobox cbxCombo=new Combobox
cbxCombo.Items.Add(tbxText.text)
This is pseudocode and not syntactically correct C# code.

Hi,
(condition ? result_if_true : result_if_false)
represents a value...
Console.WriteLine(x > y ? "X bigger" : "Y bigger (or equal to)");
is what you're looking for (note that if x > y is false... it doesn't necessarily mean that y > x).
Hope this helps.

Any way thanks for your time

Yuo are calling the WriteLine method of Console which is not an:

Try:
if (x > y)
{
Console.WriteLine("x is greater");
}
else
{
Console.WriteLine("y is greater");
}
You always pass failure on the way to success.

Can I create a subform in C#
In other words, can I put a form as a control on another form (like MS Access)
Mohammed Gouda

Hi,
yes.
a form of the same app is easy: see the Form.TopLevel property.
a toplevel window of another process is more difficult; I don't recall the details; you'll need
the window handle and call some win32 function. It has been discussed on one of the CP forums
some days ago.

Hi all
I'm stuck with a problem. I need to open video clips in my project, cut several clips from that video, and then encode those clips back to one video.
Opening and playing only those selected clips as part of the original I've figured out, but how do you output that back to an video clip.
Thanx

You can't do this natively in .NET, you will have to rely on third party SDKs.
Possibly consult the Windows Media Player SDK, Direct X SDK, or google for a SDK.

Good Day,
I have a ListView and I want to display a message box when an item is added.
Is there an EVENT that is being triggered when an item is added into the ListView?
Thanks!
|
|
|
|
|
No there is no event for that.
But it can be done. For example derive from the ListView and define an IBindingList[^]member to create a data bound listview. After that respond to the IBindingList.ListChanged event.
Also there is an article here[^] that discuses something similar.
Hope it helps!

Hi there,
is there a table control can be used in C# form in order to contain data I put during run time ( not data base table)
I need the table to organize the output ( which is some calculations performed by the application,
I read somewhere that there is a table control but must be added and referenced (dll), but I do not how!! 
help is appreciated
thanks in advance
There is always something to learn

[edit: misread table control for tab control]
Their is a table control which can either be a listview with detail view or the grid control. They are both included in the standard System.Windows.Forms namespace.

Hello all,
We are going to start a migration project, i,e from C++ to C#, i do not have any idea on C++ absoultely, there would be many problems while converting pointers, Multiple inheritance in C++ and etc, could anyone help me in providing some information about the issues in converting the C++ code to C# code?

if you want to have a clean result of the C# version, i don't think it can be done the way you have imagined, by converting the pointer, multiple inheritance and so on.
you have to understand first the whole idea what is in the program you want to convert in C++ version, and then redesign it in C# version. but unfortunately for you, you have to understand first the C++ version.

How can you possibly undertake this work if you don't understand C++? Do you seriously expect to gain an understanding of such a complex language from a single forum post?
Your company has serious problems if people are assigned to projects that they don't have the technical skills for.

We produce a product which assists with this (named very creatively as 'C++ to C# Converter'), however as the others have noted it is futile to attempt this if you don't already have a very good grasp of C++. A converter helps with the grunt work, but the most complex aspects of conversion are the areas that often need some manual adjustments and if you don't know C++ you'll have great difficulty ensuring that the original functionality is preserved. Also, some C++ code simply cannot be converted to C#.

I'm reading a text file using a stream read and my code goes like this
<br />
FileStream file = new FileStream("c:/data/theData.txt", FileMode.Open, FileAccess.Read);<br />
StreamReader streamReader = new StreamReader(file);<br />
<br />
String line = streamReader.ReadLine();<br />
<br />
while (line != "")<br />
{<br />
if (line.Equals("<data>"))<br />
{<br />
.....
}<br />
<br />
line = streamReader.ReadLine();<br />
}</data>
the problem is that whenever i run my program, this error occurs on runtime:
"Object reference not set to an instance of an object" and it's pointing at the
"if(line.Equals(""))"... what's wrong? i used to do this in java and it works..
