It looks like your SettingsPropertyValueCollection is getting corrupted, so that the values in the _Indices HashTable doesn't correspond to the size of the _Values ArrayList.
The class itself should be pretty well tested, so there might be something in your code that is accessing some memory that it shouldn't. Typically that's only possible when using reflection, unsafe code blocks or calls to unmanaged code.
Despite everything, the person most likely to be fooling you next is yourself.

greetings,
I am trying to write a program that will communicate with another application using xml messages over tcp/ip.
The host machine has a public IP address and i will send the xml messages to a particular port number.
The documentation of the host application makes numerous references to socket programming so i'm guessing that is a hint to any potential users.
So I was wondering how i can use dot net (C#) to the following:
firstly, create the xml documents(xml messages)
secondly, send these xml documents over the network over tcp/ip sockets
thirdly, view the response from the host machine

Use XmlDocument to create XML. Then you can send the complete string of that XML (xmlDoc.OuterXml) using TcpClient. Then using TcpClient you can also wait for the response.
|
|
|
|
|
You can send them as byte array after adding headers to distinguish messages from each other.
Edit: removed typo

I have used the web browser control in my C# Windows Application. And i have written following code in that application for previewKeyDown event of webbrowser control.
But when user press the key M , Message box should be displayed once. But it is displayed twice.
Source code:
private void webBrowser1_PreviewKeyDown(object sender, PreviewKeyDownEventArgs e)
{
if (e.KeyData== Keys.M)
{
MessageBox.Show("User has pressed key M", "Key press alert");
}
}
actually event of key press occurs once. But message box is displayed twice . Need help ?
Thanks in Advance.

it comes only once in my test app. see first, if :
this.webBrowser1.PreviewKeyDown += new System.Windows.Forms.PreviewKeyDownEventHandler(this.webBrowser1_PreviewKeyDown);
called twice...
|
|
|
|
|
First message box comes but when you click on Ok button same message box appears again on the screen. that event occurs again. how this happens ?
|
|
|
|
|
Have you accidentally added the event hook twice somewhere? That would be the most logical explanation.

Hi
Is it possible using GDI+/.Net Framework to draw text along a path. For example, I want to draw a bezier curve that looks like an "S" shape, and I want the text to render along the shape.
Thanks
|

|
|
I'm sure it is possible. You'll probably have to create a custom text control in order to do so.

Hi,
How can set focus to the next row in the DataGridView? (triggering a event like button_click)

Hi,
I'm trying to change the background colour of my desktop. Here's the code I'm using:
RegistryKey rkWallColor = Registry.CurrentUser.OpenSubKey("Control Panel\\Colors", true);
rkWallColor.SetValue("Background", "0 0 64");
rkWallColor.Close();
I'm sure that I'm doing it right, but the desktop colour wont change. I've checked the registry key and it has been changed. Am I accessing the wrong key?
I'm using windows xp.
Can anyone see what I'm doing wrong?
Thanks

Changing only the registry values will not change the background color.
Have a look at the API: SetSysColors.
It is present in user32.dll
If you want to change the wallpaper and get related information, have a look at SystemParametersInfo which is also present in user32.dll
regards

Thanks, after turning my computer on this morning the background colour has changed, so it seems as though it is working, just not picking up the changes until a reboot..
I thought I should be able to do it through the registry keys as with changing the wallpaper (Which I'm already doing)?
I'll have a look at SetSysColors and see where I get.
Thanks

|

okay, after looking into it, it seems that I need to use a combination of the api, and registry keys.
I've got it working wonderfully!
Thanks you again for the gentle nudge in the right direction
