You have to decorate these strings in your .net interop interface/class/struct with a MarshalAs(UnmanagedType.BStr) attribute.
|

Tried adding MarshalAs attribute. It didnt make any difference.
Here is the code I am using..
public bool CreateFile([MarshalAs(UnmanagedType.BStr)]string file,string app)
{
FileStream fileStream = new FileStream(file,FileMode.OpenOrCreate);
/* write some stuff in the file here*/
}
Unfortunately, it is not creating a proper filename if the string is unicode.
The above function works correctly if I execute it directly from .NET(without MarshalAs attribut)
Any suggestion is welcome..This has me stumped for over a week now.
Thanks

Hi everybody!
I'm using the MS web browser control to host an HTML for use as HTML Editor.
I have to make additional changes to the HTML content before saving to document, so that I want my own save function. But I dont know how to mark the document status as saved, changed...so that it wont display prompt dialog when I close or navigate to another page.
All I want is to be able to get/set the status of the document MANUALLY.
can anyone help?
many thanks!
What U PAY is what U GET!!!

Hi,
I am using Mnemonic with label controls. I have set UseMnemonic true. In design time underline character appears but in runtime , underline character appears only after pressing Alt key not before that. What I am missing?
Any clue?

Isn't that the normal behaviour. With the exception of Office applications, everything else on my PC only shows the underline when the alt key is pressed. (Office applications, if you didn't already know, are developed using their own GUI toolkits separate from Windows - normally they are a little ahead of the curve, but when the Windows GUI catches up it does things a little differently)

Its a windows setting. Look under display properties, appearance, effects, last option, untick that

hi,
I have an application developed in MFC( VC++ 6.0 ) where the information all the parameters of CreateFont function of CFont is stored in a file. Now I am rewriting the whole application in c#. But I am not able to map all the paramters of CreateFont to the Font class of c#  and to provide backward compatibility it is important. Can anyone suggest me a possible workaround for this problem ????

It would be helpful to understand the format of the file.

hi,
The information about the font is stored in the follwing format:
1. LoByte (Point size for Font)
2. LoByte (Point size for Font)
3. LoByte(LoWord(Height))
4. HiByte(LoWord(Height))
5. LoByte(HiWord(Height))
6. HiByte(HiWord(Height))
7. LoByte(LoWord(Width))
8. HiByte(LoWord(Width))
9. LoByte(HiWord(Width))
10. HiByte(HiWord(Width))
11. LoByte(LoWord(Escapement))
12. HiByte(LoWord(Escapement))
13. LoByte(HiWord(Escapement))
14. HiByte(HiWord(Escapement))
15. LoByte(LoWord(Orientation))
16. HiByte(LoWord(Orientation))
17. LoByte(HiWord(Orientation))
18. HiByte(HiWord(Orientation))
19. LoByte(LoWord(Weight))
20. HiByte(LoWord(Weight))
21. LoByte(HiWord(Weight))
22. HiByte(HiWord(Weight))
23. Italic(byte)
24. Underline(byte)
25. StrikeOut(byte)
26. CharSet(byte)
27. OutPrecision(byte)
28. ClipPrecision(byte)
29. Quality (byte)
30. PitchAndFamily(byte)
31. Length of face name (L)
For Length L following 2 bytes will be repeated
1. LoByte (character of face name)
2. HiByte (character of face name)
Here the first inforation i.e.Point size for Font is the value which we get from the
CFontDialog::GetSize()
function and the rest of the information are the the parameters of the CFont::CreateFont( int nHeight, int nWidth, int nEscapement, int nOrientation, int nWeight, BYTE bItalic, BYTE bUnderline, BYTE cStrikeOut, BYTE nCharSet, BYTE nOutPrecision, BYTE nClipPrecision, BYTE nQuality, BYTE nPitchAndFamily, LPCTSTR lpszFacename ).
I am not able to map all these parameters to their corresponding c# values and thus cant open the application developed using the previous version( MFC ) and see the fonts properly.Any suggetions???

Hi,
I hope you can manipulate the follwing code and get information about the Domains
using System;
using System.Net;
class GetResolveInfo
{
public static void Main(string[] argv)
{
if (argv.Length != 1)
{
Console.WriteLine("Usage: GetResolveInfo address");
return;
}
IPHostEntry iphe = Dns.Resolve(argv[0]);
Console.WriteLine("Information for {0}", argv[0]);
Console.WriteLine("Host name: {0}", iphe.HostName);
foreach(string alias in iphe.Aliases)
{
Console.WriteLine("Alias: {0}", alias);
}
foreach(IPAddress address in iphe.AddressList)
{
Console.WriteLine("Address: {0}",
address.ToString());
}
}
}
Hope this will help you 
kss

On the class where your start up form is there is a static method called Main(). It kicks off the GUI. You need to make a descision here whether to launch the GUI or go command line. The parameters passed into the Main method are the command line parameters. If there are none then you can launch the GUI. If there are parameters then you could process them and exit.

I'm trying to return an Ampersand as a char using this code:
<br />
case 17:<br />
return '&';<br />
However, it doesn't return anything. So I tried using the unicode escape: \u0026. That didn't return anything either.
I've changed the fonts multiple times, but for some reason the ampersand just doesn't show up. Does anyone have a solution?

- What is "it" in the above phrase?
- What happens when you set a breakpoint at the return statement? Is it ever reached?
