I'm not sure what 'IOW' highlighting is, but basicly, every time the user types a character in the control, it tests for regions (any text between say '[' and ']') and then draws a transparent box over that part of the text.

I'm not what IOW is too, but i need to draw normal rich box and then highlight sections od rich edit box, like section for input and another one output. And I need to know how to draw it.

I've managed to get custom drawing in a RichTextBox by adding this line in the constructor (of the derived class):-
SetStyle(ControlStyles.UserPaint, true);
then overriding 'OnPaint'. However, it's really hard to make the control draw itself, the only way I can do it is like this:-
protected override void OnPaint(System.Windows.Forms.PaintEventArgs e)
{
SetStyle(ControlStyles.UserPaint, false);
Refresh();
SetStyle(ControlStyles.UserPaint, true);
...custom painting here...
}
this code is the only way I've found of getting the text to be drawn, or the selection, and although you can then custom paint, it doesn't paint itself correctly, it uses the wrong font.
Any ideas anyone? By the way, neither Invalidate or Update cause the control to paint itself...

I have read leppies' code briefly and I think it's much better way how to do that than "tricks" like
SetStyle(ControlStyles.UserPaint, false);
Refresh();
SetStyle(ControlStyles.UserPaint, true);
... although much more complicated.

Well, just one thing is missing - finishing it
I need it for UI (at the end I want it look like Mathematica editor) of my symbolic math library and since I started writing the kernel couple days ago I guess there are other things to do than UI But I (generally) know how to do that, at least

Friends,
How do I get the number of records in a OleDbDataReader ?
How do we move to the first record, if we reach the last record ?
<br />
OleDbCommand cmd = new OleDbCommand( "select description from test", conn );<br />
OleDbDataReader odr=cmd.ExecuteReader(CommandBehavior.CloseConnection);<br />

I am not all that familiar with this DataReader problem and if I understand the problem correctly, you need to know how many items are in the result set before you process them and you wish to do this with only one query to the server. If your db provider supports multiple results sets you can execute one query such as:
SELECT COUNT(*) as CNT FROM MyTable
SELECT * FROM MyTable
Then in your code you would read the count from the first result and once you have the count, simply use the OleDbDataReader.NextResults member to switch to next result set which is you main query. This is one call to the server and in most cases will have little performance penalty.

How can I create Windows Installer setup package for my C# application if this option is not available/not working n my VS? are there any other FREE solutions?
Many Thanks,

Hi Jassim
You could try Inno Setup which is free. But you'll have to distribute the .NET runtime and stuff like that on your own (unlike the VS installer, Inno wont automatically find and add dependencies for you - you gotta add them to the setup yourselves)

Even the VS.NET installer requires you to ship the framework separately. Currently it just throws up a Message Box with a message informing the user that they need the framework to install the program (the message is customizable)
There is a bootstrapper sample on MSDN that is supposed to detect/install the framework if needed, but I couldn't get it to work/compile.

You've also got a merge module (.msm) to play with.
The cmdline with dotnetfx.exe has many options to check against the possibly existing run-time.

Yes, but if you include the merge module it will fail to build.
"ERROR: dotNETFXRedist_x86_enu.msm must not be used to redistribute the .NET Framework. Please exclude this merge module."
For some unknown reason MS decided they wouldn't let you include it in a setup project. I would think that defeats the purpose of having it in the first place; perhaps its for detected dependencies (mscorlib, etc).

I have this function exported in a Windows API DLL written in C:
TESTECS_API int fnTeste(char* pOutput)
{
char buffer[] = "0000MENSAGEM DE TESTE ";
memcpy(pOutput, buffer, sizeof(buffer));
return 0;
}
I need to call this function from a managed C# code, passing a structure as the char* parameter. The parameter cosists of a set of strings, each one representing a piece of that BIG string that is being copied to the strucutre in the unmanaged DLL.
Here is how I defined the code to call the DLL in managed code:
[StructLayout(LayoutKind.Sequential , CharSet=CharSet.Ansi)]
public struct Resposta {
[MarshalAs(UnmanagedType.ByValTStr, SizeConst=2)] public String FIELD1;
[MarshalAs(UnmanagedType.ByValTStr, SizeConst=2)] public String FIELD2;
[MarshalAs(UnmanagedType.ByValTStr, SizeConst=20)] public String Mensagem;
}
public class Win32API {
[DllImport("testecs.Dll")]
public static extern void fnTeste( ref Resposta r);
}
public class App
{
public static void Main()
{
Resposta r = new Resposta();
Win32API.fnTeste(ref r);
Console.WriteLine(r.FIELD1);
Console.WriteLine(r.FIELD2);
Console.WriteLine(r.Mensagem);
}
}
The result that comes out of this program is:
0
0
MENSAGEM DE TESTE
The result I´m expeting is:
00
00
MENSAGEM DE TESTE
The problem is that the marshaller is putting an \0 in the end of each string of the strucutre, even if I state that is a ByValTStr and implicit tells its size. Does anyone know how to "automatically" remove te zero terminator during the marshalling process, so that I get the expected result ? Does anyone know any other method that I can use to solve this problem ?
thanks in advance

Hi all,
is there any Grid Control free sources usable with C# for Windows CE ? Something like Dundas grid. As I might understand even DataGrid control is not supported under CE.NET in VS 7, so any info/links will be strongly appreciated.
Thanks in advance,

Looking at the documentation included with the final beta of VS.NET 2003 the DataGrid lists the Compact Framework as a supported platform.
I know next to nothing about the .NET CF though so they could be meaning something else by that.

May I ask you which build do you use?
I have VS.NET codename Everett Enterprise Architect
MS Development Environment 2003 beta Version 7.1.22.15 and
MS .NET Framework 1.1 Version 1.1.4322
That's what's written in About... box
Unfortunately DataGrid doesn't list .NET CF as supported platform
