The text wasn't cleared when you hit the keys because you're handling the keydown event and resetting the selection length to 0 before your KeyDown code is finished and before the textbox gets the keystroke.
What I'm guessing you have to do (I don't know what your requirements are) is in your KeyDown event handler, save the current SelectionStart and SelectionLength values before you change anything, then restore them back to what they were before after you're done making any changes.
private void textBox_Receivers_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e)
{
int saveSelStart = textBox_Receivers.SelectionStart;
int saveSelLength = textBox_Receivers.SelectionLength;
textBox_Receivers.SelectionStart = 0;
textBox_Receivers.SelectionLength = textBox_Receivers.Text.Length;
textBox_Receivers.SelectionFont = new Font("Arial", 8, FontStyle.Regular);
textBox_Receivers.SelectionStart = saveSelStart;
textBox_Receivers.SelectionLength = saveSelLength;
}
I have no idea why you would want to do this anyway. With every keystroke, you're resetting the font for your entire textbox to Arial 8pt. Why would you want to do this? Why not set it once for the entire textbox and be done with it?

hi, thx look for my solution:
<br />
private void textBox_Receivers_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e)<br />
{<br />
if(textBox_Receivers.Rtf.IndexOf("\\ul") >= 0) <br />
{<br />
if(e.KeyCode == Keys.Back || e.KeyCode == Keys.Delete || char.IsDigit((char)e.KeyCode) || char.IsLetter((char)e.KeyCode))<br />
{<br />
int SelectionStart_old = textBox_Receivers.SelectionStart;<br />
<br />
if(textBox_Receivers.SelectionLength != 0)<br />
{<br />
textBox_Receivers.SelectedText = "";<br />
}<br />
<br />
textBox_Receivers.SelectionStart = 0;<br />
textBox_Receivers.SelectionLength = textBox_Receivers.Text.Length;<br />
textBox_Receivers.SelectionFont = new Font("Microsoft Sans Serif", 8, FontStyle.Regular);<br />
textBox_Receivers.SelectionStart = SelectionStart_old;<br />
textBox_Receivers.SelectionLength = 0;<br />
}<br />
}<br />
}<br />

I don't get paid enough to fix other peoples code on command. You look for your solution - We help. Besides, I already gave it to you, if you would have bothered to read it.

I'm wondering how I can go about making a property list sorta like the one found in Visual Studio .NET. The way VS handles properties for Windows Forms is exactly what I need for a project I'm working on. Can anyone point me in the right direction to find out some more information on how to make this sort of thing?

I have a program that creates graphs which you can save and load.
I have successfully associated my icon to my program so that when I click on a graph file it opens the program  ( in registry ie. "c:\...\...\program.exe "%1"") however it does not load my graph I use the open file dialog do I need to write specific open file code?? Any thoughts would be great.
Cheers*

If you already associated your file type to your program
So did you handle the file path passed in main function?
ie the file you opened passed as command line argument to your program so you need to handle this issue
If you not associated your file type to your program by
using window explore or when you create setup project
use File Types Editor to do it

How do I do to play a raw data?
Like the data that's in the data chunk in a wav file.
The other values could I fix later.

Please tell me how to implement a method that will look to its own class and return (eg. an array) of all members of this class (its suppose to use reflection, this kind of reflection is called 'self' if I remember good...)
I tried something like that:
<br />
ble b = new ble();<br />
<br />
Type t;<br />
FieldInfo[] mi;<br />
t = typeof(ble);<br />
mi = t.GetMembers();<br />
<br />
foreach(MemberInfo mem in mi)<br />
this.listBox.Items.Add(mem.Name);<br />
<br />
and it wrote some strange stuff... I just want to have all the members of 'ble' class (eg. string s, int i, etc)

Hello
Suppose we have the next class:
class A
{
public int memberVariable;
public void Method1() {}
public void Method2() {}
}
And the next code somewhere:
Type type = typeof(A);
MemberInfo[] mis = type.GetMembers();
foreach (MemberInfo mi in mis)
{
System.Diagnostics.Debug.WriteLine(mi.Name);
}
So, we'll get something like this in output window:
memberVariable<br />
GetHashCode<br />
Equals<br />
ToString<br />
Method1<br />
Method2<br />
GetType<br />
.ctor
What is wrong? You have all your own members and inherited members.

My variables were private... there is no way ti display them?

try
type.GetMembers(
BindingFlags.NonPublic|
BindingFlags.Instance|
BindingFlags.Static
);

how to retrieve the type of each field? I mean, I would like to know that, for example, 's' is a string
further questions - is it possible to retrieve also information about arguments that funcion takes and the return type?
|
|
|
|
|
Type type = typeof(A);<br />
MemberInfo[] mis = type.GetMembers();<br />
foreach (MemberInfo mi in mis)<br />
{ <br />
System.Diagnostics.Debug.WriteLine(mi.Name + ": " + mi.MemberType.ToString());<br />
}
|
|
|
|
|
it doesnt work - I tried and MemberType gives exactly the same as MemberType.ToString() - it gives only general info (method, field, etc) and I want detailed information (string, int, char, etc)

You want ReflectedType. All your questions can be answered by MSDN[^] though.

Hi all,
I've built a Windows Service wich accepts arguments in the main function so I can execute the exe like <code>MyWindowsServ.exe –install</code>.
I can install the service, I can run it, and everything runs ok.
Now, what I wanted to do was to install the service so when it starts it can take some arguments as well.
If you look at the COM+ Event System service properties (for instance) in your control panel, you can see that the path to executable is something like this <code>C:\WINDOWS\system32\svchost.exe -k netsvcs</code>
Is there a way I can add these arguments to my ProcessInstaller or ServiceInstaller or something like that?
Thanks,
<i>vSoares</i>

You can pass startup parameter to windows service but however rather than acceptin arguments in Main Method Windows service accept arguments and handle them in OnStart MethodTo setup startup parameter
Open the windows Services MMC snap-in
Select your Service->Properties-->General
You will find Start Parameters you can write your start parameters in it To add this information when you install windows service you have to write start parameters in registry under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services
start up parameter stored in ImagePath
There are some articles at codeproject about custom installation of Windows service like
Install Service Using Script[^]
ServiceInstaller Extension That Enables Recovery and Autostart Configuration

I would like to be able to use some old ANSI C functions but have access to them using a new GUI built in C#. Basically I'm trying to take a comsole app and make it windows based. Is there anyway to do this? I have tried adding the reference but, even though the code is compiled under .NET, it doesnt seem to like it. ANy suggestions? Or am I SOL?
Thanks in advance

put your c code in dll and use this dll in your c# code
P/Invoke will help you to do this
look at question titled using c++ dll in this forum page
i provide link to P/invoke article
