What is mcWebService?
To install a web service, all you need to do is copy it into an IIS5 "application" folder.

It's not a WebService...he's having the obligatory problems with Windows Services that everybody seems to have...

I am trying to figure out how to set up a listview control so I can draw the items myself. Can anyone help me with this?
Thanks in advance for taking time to help me out!

I use this C# code to read a text file line-by-line, process each line and then write it back to disk. It works beautifully, if the file contains only the first 127 ASCII chars. The chars 128-255 are simply skipped. How can I fix this?
StreamReader sr = new StreamReader(m_sSrcFileName);
StreamWriter sw = new StreamWriter(m_sDestFileName);
try {
long savedBytes = 0;
do {
string oldline = sr.ReadLine();
string newline = ProcessLine(oldline);
savedBytes += oldline.Length - newline.Length;
sw.WriteLine(newline);
} while (sr.Peek() != -1);
Console.WriteLine(savedBytes + " Bytes saved");
return savedBytes;
}
Remember that the input files are not 2-bytes-unicode, but 1-byte-extended-ASCII.
Thank you in advance.

Have you tried System.Text.Encoding.ASCII?
eg. StreamReader sr = new StreamReader(m_sSrcFileName, System.Text.Encoding.ASCII);

Yep I tried your suggestion and now it does not get skipped, however it writes back the wrong char to the file: for example the ù char becomes ?... I also tried to set the same encoding for the StreamWriter but with no success... do you have other suggestions?

Have you tried the encodings such as UTF8?
Give them a chance! Do it for the kittens, dear God, the kittens!
As seen on MS File Transfer: Please enter an integer between 1 and 2.

Ooops, sorry, saw "ASCII", didn't see "Extended".
Hmmm... supported codes:
Encoding.ASCII
Encoding.Unicode
Encoding.BigEndianUnicode
Encoding.UTF7
Encoding.UTF8
While the U in UTF is Unicode, I'd lay good money that they are 7 and 8 bit versions, so I'm guessing leppie is right to suggest UTF8.

Nope. I tried every encoding, apart from BigEndianUnicode... and it does not work. Now I don't have time enough to do a deep debug session, but I promise that tomorrow I'll try again...

Seems Encoding doesn't support Extended ASCII - now that is bizarre.
You might be well advised to open a standard stream, rather than a text stream, read the whole lot into a byte array and convert that to a string (possibly using System.Text.Encoding.GetChars, at worst using a for loop).

1) How do I cause a certain tab in my tab control to be automatically selected when a user does the follow:
a) Clicks an option in the Tree Control.
b) Clicks an option in from the Menu on the top toolbar.
Many Thanks,

pls help this problem,
As you know, you can't delete minimize/maximize button in MDI child form
even if you set the FormBorder to None.
So I override resize method of childform.
But After that, I can't put button in groupbox of child form 'cuz
application lost focus when child form appears.
Here is very simple example,

Anyone has same problem with me?
I think this is another bug of MDI in .NET......

Hello,
I write program which uses some functions from legacy dll written in Delphi.
The problem is that Delphi have type "shortstring" which is very specific for this language and I can't marshal this type.
Pascal code:
<br />
...<br />
type<br />
TDLLIn = record<br />
....<br />
Typekey: shortstring;<br />
end;<br />
<br />
<br />
function Init(dllIn: TDLLIn): integer;<br />
begin<br />
....<br />
end;<br />
C# code:
<br />
public struct TDLLIn<br />
{<br />
....<br />
<big>[MarshalAs(UnmanagedType.AnsiBStr)]</big><br />
public string Typekey;<br />
}<br />
<br />
public class Wrapper<br />
{<br />
....<br />
[DllImport("DelphiDLL.dll", CallingConvention=CallingConvention.StdCall, EntryPoint="Init")]<br />
static extern int Init(TDLLIn dllIn);<br />
}<br />
I've tried marshal as AnsiBStr, as byte array (MarshalAs(UnmanagedType.ByValArray, SizeConst = 256, ArraySubType = UnmanagedType.U1)) and many others ways but still no success.
Marshaling Pascal shortstring is impossible for me.
If anyone found a way to do this please inform me.
Best regards
Adam Plucinski

Tried [MarshalAs(UnmanagedType.LPStr)] ?
MSDN[^].
You may also implement a custom marshaler (ICustomMarshaler). That's an advanced topic, but standard marshaling is supposed to work for standard types only...
sometimes it helps to look at the IL generated code

[MarshalAs(UnmanagedType.LPStr)] is rather for "PChar" Delphi type
I've tried all possibilities - custom marshaler it is last possibility but I must resolve internal structure of shortstring, maybe Borland will help 
|
|
|
|

If you can get a pointer on the actual structure of shortstring, you can hack it, that would avoid relying on Borland.
Btw, I am pretty sure lotsa people have or will have this problem too if shortstring is a lot used in applications.
Another possibility is to avoid direct use of a shortstring. For instance, if the DLL (or intermediate DLL) passes a char*, it could be the actual Delphi's dll job to convert this char* to shortstring. At this point, I don't know sh*t about Delphi.

I'm sure too.
Many Delphi programmers use shortstrings because if they use normal strings, which size is dynamically counted they must use Borland Memory Manager dll which of course must be instaled in system. They don't use PChar but they could.

You're right but if you are not author of this Delphi DLL you can't do this.
I was Delphi developer - but I switched to VS .NET

Use an intermediate DLL.
VS.NET String -> marshalled as char * -> DLL -> DLL function exposes a char * as input parameter -> the implementation creates a shortstring thanks to the constructor (delphi dependency here) -> this DLL calls the initial DLL, passing a shortstring as input parameter -> you're done.

Yes - with one dll it is no problem to do this.
..but academic problem still exists
when you have 10 dll's making 10 wrapper dll's is kinda boring
|
|
|
|
|
No, you need only one.
I am surprised that there is no article or existing workaround, if that's a real issue a lot of Delphi.NET developers have.
If that's a real issue, then don't miss the opportunity of writing a CP article. And get known!
