Help!
I'm trying to retrieve data from database and put it on richtextbox control.
my problem is : the richtextbox control doesn't read the "\r" and "\n" character (13 and 10 in ASCII, return carriage and line feed). so the data was not displayed on different line but go through one line.
any information on it?
thankz a lot
regards

more information,
I try to display it in RTF Format.
I think RTF Format doesn't accept "\r" and "\n".
Am I correct?
anyway to make RTF Format could read "\r" and "\n" character?

...In fact, a carriage return line feed is never expected to be found in an RTF file...
Just found that in RTF Specification for Word2007.
I just replace the "\r" "\n" with "\line" in RTF and it worked for now..

Hi all,
What can I use within C# to replace the function:
LRESULT SendMessage(
HWND hWnd,
UINT Msg,
WPARAM wParam,
LPARAM lParam
);
Many Thanks in advance

OK, so I'm using PInvoke - doing the following:
[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = false)]
static extern IntPtr SendMessage(HandleRef hWnd, uint Msg, IntPtr wParam, IntPtr lParam);
But I'm receiving the following error:
Error 2 The modifier 'extern' is not valid for this item
Error 3 Expected class, delegate, enum, interface, or struct
Why ???

where did you find "HandleRef"? that's why the compiler expected class, delegate, enum, interface, etc I think..
try the code below.. I have no idea how to use it because it only return the message ID which I don't know how to process..
<br />
[DllImport("user32.dll", CharSet = CharSet.Auto)]<br />
private static extern IntPtr SendMessage(IntPtr hWnd, int wMsg, IntPtr wParam, IntPtr lParam);<br />

Where do I place it. At the moment I placed it here (is this correct?
...
using System.IO;
[DllImport("user32.dll", CharSet = CharSet.Auto)]
private static extern IntPtr SendMessage(IntPtr hWnd, int wMsg, IntPtr wParam, IntPtr lParam);
namespace WindowsService
{
...
Many thanks for the reply

Hi,

you have to put these lines inside a class, any class would do (I use LP_user32 for all
user32.dll functions).

Yep,
put it inside a class..
search in microsoft documentation for more info about windows messaging, the message type, and other info..

Ok, I'm trying this ....
class WindowsService : ServiceBase
{
[DllImport("user32.dll", CharSet = CharSet.Auto)]
private static extern IntPtr SendMessage(IntPtr hWnd, int wMsg, IntPtr wParam, IntPtr lParam);
But I receive this:
Error 1 The type or namespace name 'DllImport' could not be found (are you missing a using directive or an assembly reference?)

Visual Studio is kind enough to include the probable fix in the error message.
MSDN will tell you which namespace DllImport belongs to.

Is it possible to show a MessageBox from a Service developed in C# ?
Many Thanks

When you say "Service" do you mean that your C# program is running as a Windows Service? That's my assumption here, and yes it's possible. Whether or not it's advisable is another matter.
Now when I say "possible" I mean that the code will compile and build, and the .exe can be installed as a Windows Service and run. Often times one of the main reasons to develop a solution to run as a Windows Service is so that it can run even when no user is logged in to the computer. Now if that's the case, and the code finds it way down the path to where the MessageBox is .Show()'n, I don't know what will happen. Maybe nothing. Maybe it's displayed and causes the Service to stop executing until the nonexistent user clicks the unseen "OK" button.
Of course you could try it and see what happens. If you do, post your results here so everyone can know, too. Then try to find out if a tree falls in the forest....

If you need more information on the code...
//Method for converting a structure or object into a byte[]
public static byte[] RawSerialize(object anything)
{
int rawsize = Marshal.SizeOf(anything);
IntPtr buffer = Marshal.AllocHGlobal(rawsize);
Marshal.StructureToPtr(anything, buffer, false);
byte[] rawdatas = new byte[rawsize];
Marshal.Copy(buffer, rawdatas, 0, rawsize);
Marshal.FreeHGlobal(buffer);
return rawdatas;
}
//Method for converting a raw byte[] from a binaryReader stream to the original structure
public static object RawDeserialize(byte[] rawdatas, Type anytype)
{
int rawsize = Marshal.SizeOf(anytype);
if (rawsize > rawdatas.Length)
return null;
IntPtr buffer = Marshal.AllocHGlobal(rawsize);
Marshal.Copy(rawdatas, 0, buffer, rawsize);
object retobj = (Word)Marshal.PtrToStructure(buffer, anytype);
Marshal.FreeHGlobal(buffer);
return retobj;
}
These are the methods I use to convert to byte[] and back to my struct.
