Oh great, blame the wife for giving an overly static/Shared and slow response. 
Most of my classes do have a couple of static data members, often for statistical purposes (counting or holding a list of all instances), and for logging parameters. But these are just tools, they don't reflect application-domain properties.

Now it all makes sense; I have fixed my earlier message accordingly.

What you need is a static class that can be shared between forms. You can use Session or Application state for this if you are using ASP.NET, however, if the object is large it may not be the best way to handle it.
You can also pass the value you are interested in from form1 to form2 via properties, events, constructors.

</specialSources>
</loggingConfiguration>
Everything works fine.
The only issue i have, is with the "Unprocessed Category" special source.
Reading the documentation from msdn for EntLib L.A.B., i undestood that when you try and log to a Category that is not specified, that LogEntry is directed to the Unprocessed Category source.
In the above example though, if i log a Verbose message, and define the category in the LogEntry to be let's say "Undefined" (which is not specified in the configuration), i loose that LogEntry completely. Ideally, when the application attempts to log, it should do the following steps:
-Get the LogEntry and pass it through the logfilters.
-If it passes through the logfilters, find the category that the logentry specifies, and pass it to the listeners in that category
(in our current case, category is "Undefined")
-If you can't find the category specified in the LogEntry,go to the "Unprocessed Category" special source and log it to the listeners specified in there.
BUT:
!!Last step is never executed. I do not get the log in my flat file!!
NOTES:
-I have double checked, and the filters for both
the listeners and the categories are not blocking the LogEntry because of the level of message (verbose, information, etc...)
-The other special sources ("All Events" and "Logging Errors & Warnings") work fine.
Any suggestions on why this is the case?
Any hints would be appreciated.

Shtel

Hi Experts,
This should be a very trivial question for you guys.
I have an object with me. This object is an object of a class who is inherting from an abstract base class. I want to know what is that base class.
Let me give you an example
Say I have 2 abstract base classes namely MyBaseClass1 and MyBaseClass2 which is inheriting from a Form class so my code would be something like this.
abstract public class MyBaseClass1 : Form
{
abstract public void MyMethod1();
}
abstract public class MyBaseClass2 : Form
{
abstract public void MyMethod2();
}
I have many forms which are inheriting from these base classes. For example
public partial class Form1 : MyBaseClass1
{
public Form1()
{
InitializeComponent();
}
public override void MyMethod1()
{
MessageBox.Show("mymethod1");
}
}
These forms will be opened in an MDI form. I want to know which is my active form. This i can get from the property of the MDI form ActiveMdiChild. But this property will return me a Form object. I want to know what is the base class of this form object i.e. whether it is MyBaseClass1 or MyBaseClass2. I also want to create an object of this base class if possible.
Please do let me know if I hv not explained my query properly.
Please help!
Thanks in advance!
Regards,
Samar

if (ActiveMdiChild is MyBaseClass1)
{
// your code hier
}
|
|

|

You have a few options, you can as previously stated use the is keyword and see if it's the type you are looking for.
An alternative is to actually look at the BaseType:
Type t = ActiveMdiChild.GetType();
Type baseClass = t.BaseType;
object something = Activator.CreateInstance(baseClass);
However, unless there is a common base class that you can cast to so that you can use it then you are back to checking the actual type and casting to that.
So depending on what you have and what you need you can either have a series of if statements checking for the types or the above method where you will be able to create and use your base class without necessarily knowing exactly what it is.
My current favourite quote is: Punch them in the face, see what happens!

Hmm.. This looks good but i wont get the methods of the base class object in the intellisense here. Is there a way of getting that too? Maybe i am asking for too much here.

Samar

I am having an issue with this. I need to create a folder in the current users application data folder to store settings but I cannot. Every time I try to use Directory.CreateDirectory(Environment.SpecialFolder.MyDocuments + "/JFE/Settings") Or anything else under SpecialFolder it will just create a folder in the application's directory with a name like Personal then inside this directory it will make the folders I requested. Why does it do this? I printed out the string for the special folder and looked at it and it is correct but for some reason it creates my folders in the current program's directory.

Try this:
Directory.CreateDirectory(Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments), "JFE/Settings"))
Good luck
PS: The big change is Environment.GetFolderPath. Path.Combine I just inserted because it's better to use that than concatenate the path using "+"

With that little information, no - no-one can help.
We would need a better description of the problem, and probably a small fragment of relevant code (use the "code block" widget to preserve formatting) to show us what you are doing.

Windows controls appereance by default depends on selected theme in windows.You can avoid it by creating your own theme independant styles for each of them.Similar job has already been done for MFC here at cp ^.

At first you have choosen wrong forum to post your question.You should post it to ASP.NET forum.
This article explains how to solve it and lots more.

I want to register a hotkey(for example:Ctrl+Shift+A) to do such a thing:
When I press the hotkey, I hope it will input a sentence "Hello!" at the position of current cursor in a outer active window, such as Microsoft Word,NotePad,etc.
Now I have completed the registration of the hotkey with:
[System.Runtime.InteropServices.DllImport("user32.dll")]
public static extern bool RegisterHotKey(
IntPtr hWnd,
int id,
uint fsModifiers,
Keys vk
);
.....
RegisterHotKey(Handle, 150, 2|4, Keys.A);
.....
private void ProcessHotkey(Message m)
{
IntPtr id = m.WParam;
string sid = id.ToString();
switch (sid)
{
case "150": SayHello(); break;
.....
}
}
.......
private void SayHello()
{
MessageBox.Show("Hello!");
}
It works well! When I press Ctrl+Shift+A ,a messagebox will say "Hello!". But how to get the current active window, and input the text to current cursor, no matter where the cursor is and which application it is in?

Have a look at the SendKeys class. It may be sufficient for your needs.

I try to use this:
Process myPro = new Process();
myPro.StartInfo.FileName = @"notepad.exe";
myPro.Start();
myPro.WaitForInputIdle(1000);
SendKeys.SendWait("Hello!");
It's OK. I created this process "myPro", but how to get the process of the current active window?
can you give me the detailed code? Thanks.

No. First of all, this isn't a "give me code" web site. People here ask specific questions, while others provide advice and suggestions.
Second, it depends on circumstances. In simple situations, the process your app launches, will become the active app with the topmost window, and hence get whatever SendKeys sends. But then, the user (or a second automation-oriented app, or any app that feels like it) may suddenly cause another window, maybe another app, to get focus. The safer way is to check using GetForeGroundWindow (which requires P/Invoke techniques), or to send a message using SendMessage, or to create real inter-process communication by adapting both applications.

Thank you! I have found the solution! I compared all the handles(Toint32) of processes with Getforegroundwindow's, but it will tell me there more than one window. I observed that just the first one is the real active window, so I use "break" to quit "foreach". It works! That's so strange.
The code:
Process mypro=null;
foreach (Process thisproc in Process.GetProcesses())
{
if (thisproc.MainWindowHandle.ToInt32() == GetForegroundWindow().ToInt32())
{
mypro = thisproc;
break;
}
}
try
{
SendKeys.Send(@"{ENTER}\begin{{}split{}}{ENTER} &= {ENTER} &= {ENTER}\end{{}split{}}{ENTER}");
}
catch (System.NullReferenceException e)
{
}
Now, if I press the hotkey Ctrl+Shift+A, it will send some strings or commands to any active window. I use this to input some fixed blocks which need to be repeated for many times.

Hi
can anyone help with the following
i use filesystemwatcher to watch a folder and add a new entry into a listbox everytime a new file is created, there is a second listbox that duplicates whats in the first but with some code allows me to change the file name via a text box, works ok as long as the item in listbox2 is highlighted when i change text, however if the listbox updates while i'm in process of changing text it removes the highlight from the item i'm editing and crashes if i press enter to confirm new file name.
Ther error i get is no doubt due to it not knowing what index to change as none are highlighted.
So how can i get it to keep the file i am changing name of highlighted until i enter the new text.
private void fileSystemWatcher1_Created(object sender, System.IO.FileSystemEventArgs e)
{
listBox1.Items.Add(e.FullPath);
listBox2.Items.Add(e.FullPath);
listBox1.SelectedIndex = listBox1.Items.Count - 1;
listBox1.SelectedIndex = -1;
listBox2.SelectedIndex = listBox2.Items.Count - 1;
listBox2.SelectedIndex = -1;
}
private void listBox1_Click(object sender, EventArgs e)
{
listBox2.SelectedIndex = listBox1.SelectedIndex;
}
private void listBox2_Click(object sender, EventArgs e)
{
int itemSelected = this.listBox2.SelectedIndex;
string itemText = this.listBox2.Items[itemSelected].ToString();
Rectangle r = this.listBox2.GetItemRectangle(itemSelected);
this.textBox1.Location = new System.Drawing.Point(r.X + 217, r.Y + 520);
this.textBox1.Size = new System.Drawing.Size(r.Width + 4, r.Height - 10);
this.textBox1.Visible = true;
this.textBox1.Text = itemText;
this.textBox1.Focus();
this.textBox1.SelectAll();
}
private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
{
if (e.KeyChar == 13)
{
this.listBox2.Items[this.listBox2.SelectedIndex] = this.textBox1.Text;
this.textBox1.Visible = false;
}
if (e.KeyChar == 27)
this.textBox1.Visible = false;
}
