I don't get what you want. The combobox is on form1 and you want to interact with it ? To do this, you need to use a delegate, or pass a reference to the Form1 instance to whatever class wants to see the contents of the combo box. Either way, I would never expose the entire control, I'd add a property that sets or gets the bits you need access to.

You probably meant to ask in the ASP.NET forum ? What do you mean by a frame ? So there's a menu on one side for example, and the main page on the other ?

I have created a Class Library and within the class library I have a Windows Form. I compiled this class library and got the dll. This dll is now embedded on a HTML page using:
<object id="ndcObj" classid="http://nh-rajen/ntest/NDCDemo.dll#NDCDemo.NDCDraw" height="356" width="367">
Now I need to call a method within this dll from javascript within the page, lets say I do it onClick of a button on the page as:
function ChangeText()
{
ndcObj.setText('Test Text');
}
This however does not work and I get the error that the object has no such defined properties or methods. How do I expose my method such that I can call it from outside of the dll. The current method definition for setText is:
public static void setText(string txtValue)
{
this.textBox1.Text = txtValue;
}
Please help me out..
Thanks in advance,
Cheers,
Rajen

I didn't know javascript could talk to a .NET dll at all. So, you intend to distribute this dll to your end users machines ?

Yes. The javascript is able to access public attributes. However when it cannot access my public methods. I think there should be some trick to expose the methods inside the dll so that javascript is able to call them. Not sure how its done though..

If you're specifying the \ character in a constant string, you need to do one of these:
@"c:\schedule"
or
"c:\\schedule"
Otherwise, \ is used to define various special characters.

I have a requirement where I can drag-drop an item from ListBox to a Day on a month calendar. When a item is dropped on a Month Calendar a DragDrop event is raised. The event provides a DragEventArgs as parameter. This parameter provides X, Y screen co-ordinates. Can this co-ordinates be used to find out which day in the Month Calendar is the item being dropped?
Is there a way in which I can know which Day in the MonthCalendar is the Item being dropped?
Thanks in advance

One day, I intend to write a picture box derived control that does all the things that people try to do with it now, but it just can't do. Until I do, you need to ditch the picture box, draw the image in your own Paint handler, and draw your highlight over the top of it.

I'm having trouble with the following bit of code which generates an error at runtime. (it compiles fine) I've been working with C# for a total of about 3 hrs now, so go easy. 
Main Program:
namespace StealthLog<br />
{<br />
static class Program<br />
{<br />
[STAThread]<br />
static void Main()<br />
{<br />
string str = "test of write";<br />
<br />
StreamWriter sw = StealthLog.LogMgr.NewLogFile();<br />
StealthLog.LogMgr.LogToFile(sw, str);<br />
<br />
Application.EnableVisualStyles();<br />
Application.SetCompatibleTextRenderingDefault(false);<br />
Application.Run(new Form1());<br />
}<br />
<br />
<br />
}<br />
}
LogManager Code:
namespace StealthLog<br />
{<br />
class LogMgr<br />
{<br />
internal static void LogToFile(StreamWriter sw, string text)<br />
{<br />
sw.WriteLine(text);<br />
}<br />
<br />
internal static StreamWriter NewLogFile()<br />
{<br />
string headerString = DateTime.Now.ToString() + "---------------\n";<br />
string fullFilePath = Settings.Default.LogDirectory.ToString() +<br />
Settings.Default.LogFile.ToString();<br />
<br />
if (File.Exists(fullFilePath))<br />
{<br />
using (StreamWriter sw = File.CreateText(fullFilePath))<br />
{<br />
sw.WriteLine("test1");<br />
return sw;<br />
}<br />
} else {<br />
using (StreamWriter sw = File.CreateText(fullFilePath))<br />
{<br />
sw.WriteLine("test2");<br />
return sw;<br />
}<br />
}<br />
}<br />
}<br />
}
The problem is in the sw.WriteLine(text); in the LogToFile section.

This is your problem. Your overall class design is wrong, you should have the stream as a member and control it entirely within the class. Either way, a using block means the object is disposed of at the end of the block, so you're returning a stream, which you've also disposed of.

I have a listview that I am using and I want to hide the horizontal scroll bar (at all times) but not the vertical one (should run in auto mode). How do I do this? The data can only be displayed in the details view.
|
|
|
|
|
I found the answer so that it will hide the scroll bar properly if the data fits in the list view. It will still appear when the data is wider than the control but at least now it looks better.
this.lstGenerate.Columns[0].Width = -1;
