I haven't had it happen since I got more than 512MB ram, and set a decent size page file, however I recall windows pops a message for you if you are running out of memory. It would ask permission to increase the size of the page file. Leave it to Windows I say.

If you have knowledge, let others light their candles at it.

It's called try/catch. That's the best you can do. Besides, what *is* low memory in windows? It pages to disk, so you shouldn't have to worry about it.

Yes, you can observe the GC.GetTotalMemory, query the WMI information or use the unmanaged APIs. But as you've been told above, this does not make much sense in general... Your question makes sense, if your application itself manages chunks of memory for specific purposes, such as caching.

P.S. The situation is different, if we are talking about some kind of mobile device...

It's generally pointless to try.

Reflection with Dynamic Objects (System.__ComObject)

I am trying to access a property on a System.__ComObject by name. I can do this for normal objects:

var mapping = m.GoogleMapping as SimpleGoogleMapping;
var propInfo = googleContact.GetType().GetProperty(mapping.PropertyName);
googleValue = propInfo.GetValue(googleContact, null);

googleContact is a normal class so this doesn't cause a problem.

I tried this (outlookContact is a ContactItem retreived using Outlook Interop, but during debugging, shows as a System.__ComObject):

var mapping = m.OutlookMapping as SimpleOutlookMapping;
var propInfo = outlookContact.GetType().GetProperty(mapping.PropertyName);
propInfo.SetValue(outlookContact, googleValue, null);

But propInfo ends up being null, even though the property name is correct. I've also tried:

var propInfo = typeof(ContactItem).GetProperty(mapping.PropertyName);

without success.

Edit: Using outlookContact.GetType().GetProperties() or typeof(ContactItem).GetProperties() returns an empty list, as does GetMembers().

Does anyone know how to achieve this with a dynamic object?

I am using .Net 4

You cannot query a COM wrapper for CLR properties since it does not have any. Have you tried to extract the properties directly from the assembly which defines the COM CoClass? Something like this:

using System.Reflection;

 //... somewhere

 const string sOutlookInteropAssemblyName =
  "Microsoft.Office.Interop.Outlook";
 const string sContactItemTypeName =
  "_ContactItem";

 //... somewhere (error handling ommitted) 
 
 PropertyInfo FindProperty(string pPropertyName) {

  Assemby tOulookInterop =
   Assembly.ReflectionOnlyLoad(sOutlookInteropAssembly);
  Type tContactItemType =
   tOutlookInterop.GetType(sContactItemTypeName);

  // this is what you want I assume...
  PropertyInfo [] tProperties =
   tContactItemType.GetProperties();
 
  return tProperties.Find(Property => Property.Name == pPropertyName);
 }

Huch, there is a lot of stuff which can go wrong, I just typed in the code without checking it, but I hope you get the point.

This is not your whole code - this is only Form1. My suspicion is that you might have a problem in one of the following lines:

Note newNote = new Note();
Search newSearch = new Search();
SRLS newSRLS = new SRLS();
Alarm newAlarm = new Alarm();
QuickLaunch newQuickLaunch = new QuickLaunch();
Calender newCalender = new Calender();
Time newformtime = new Time();

To prove this, you need to set a breakpoint in your Form_Load to see if you ever actually hit the Form_Load event. If you get the exception beforehand, then it's likely that your problem is in there (and the problem is that you have something that is recursively calling the same method).

Now, your coding style - it's never a good idea to leave default names for items you have any form of interaction with in your code, so you should rename things like button1, etc, to something much more meaningful. Also, you could condense a lot of your methods down. Take this one:

if (newAlarm.Visible == true)
{
alarmToolStripMenuItem.Checked = false;
newAlarm.Visible = false;
}
else if (newAlarm.Visible == false)
{
alarmToolStripMenuItem.Checked = true;
newAlarm.Visible = true;
}

That could be rewritten more succinctly (and clearly) as:

newAlarm.Visible = !newAlarm.Visible;<br />
alarmToolStripMenuItem.Checked = newAlarm.Visible;

You could get terser than that, but this is fairly clear in what it does.

Firstly a few presentation points:

If you ever post code again, use the "code block" and "inline code" buttons differently.
You used "inline code":

private void CMS_CheckChanged(object sender, EventArgs e)<br />
{<br />
// this needs help so moake sure if the boxes will be checked or not<br />
foreach (ToolStripItem item in ((ToolStripDropDownItem)sender).Owner.Items)<br />
{<br />
if (item.GetType() == typeof(ToolStripMenuItem))<br />
{<br />
if (item == sender)<br />
((ToolStripMenuItem)item).Checked = true;<br />
else ((ToolStripMenuItem)item).Checked = false;<br />
}<br />
}<br />
}

If you had used "code block" instead it would have preserved the formatting:

private void CMS_CheckChanged(object sender, EventArgs e)
   {
   // this needs help so moake sure if the boxes will be checked or not
   foreach (ToolStripItem item in ((ToolStripDropDownItem)sender).Owner.Items)
      {
      if (item.GetType() == typeof(ToolStripMenuItem))
         {
         if (item == sender)
            ((ToolStripMenuItem)item).Checked = true;
         else ((ToolStripMenuItem)item).Checked = false;
         }
      }
   }

See how much easier it is to read?

There is a "Preview" button at the bottom - try it and see if it looks readable!

Also, don't post your whole file - just the relevant bits! Otherwise we have to scroll through the whole lot to get to the reply button - this discourages people from bothering...

Secondly general good things to do in code:
In the example above (and others) you are casting the sender parameter directly to a ToolStripDropDownItem. What happens if you re-use the method? Answer: your program crashes with a "cannot convert" error. Instead, always check before you cast. Either use:

if (sender is ToolStripDropDownItem_
   {
   ToolStripDropDownItem item = (ToolStripDropDownItem) sender;
   ...
   }

ToolStripDropDownItem item = sender as ToolStripDropDownItem;
if (item != null)
   {
   ...
   }

I prefer the later as it makes the null check explicit.
This is part of what is called "Defensive Programming" and trust me, it is something well worth getting into the habit of!

Real men don't use instructions. They are only the manufacturers opinion on how to put the thing together.

I bet you have same kind of code (like the one given below) in Form2 also.

Form1 newForm1 = new Form1();
private void button11_Click(object sender, EventArgs e)
{
newForm1.Visible = true;
}

I'm not looking into your code, as you're abusing the CODE and PRE tags: regular text needs neither, multi-line code snippets need PRE tags so indentation gets preserved.

The most popular way to create an SOE is by referring to some property inside its own getter/setter.

It has been a while since I did winForms, but shouldn't you actually implement InitializeComponent if you are going to call it in the constructor?

Also give your controls reasonable names. Unless your app is replicating a phone or a calculator you should never have things like button7 and button9.

The WinForms designer implemented InitializeComponent in a Form1.Designer.cs source file, which is why you don't see it in the OP's source. Notice that the class is declared as partial - that allows a single class implementation to span multiple source files.

You probably have the Form2 creating a new Form1 but you didn't post that code.

A word of advice, next time put the question/problem/error before the code. At first I couldn't see what you were asking, if anything!

If you have knowledge, let others light their candles at it.

Well, your program contains an infinite (or too deep) recursion. We cannot really tell where, since you have not posted your whole program. As adviced above, set breakpoints in the constructors at InitializeComponent of both forms you are instantiating. Then, step into the code and observe what is happening there... Have you manually modified the IDE generated InitializeComponent method? Have you used Designer to put your form together or have you done it manually?

By the way (to the english native speakers): does the verb "to squrid up" really exist?

And what is the problem you have with this task?
If you want to add a button to an existing group on existing tab, I think it would be easier to do it in VBA.

protected override CreateParams CreateParams<br />
        {<br />
            get<br />
            {<br />
                CreateParams cp = base.CreateParams;<br />
                cp.ExStyle |= 0x20;<br />
                return cp;<br />
            }<br />
        }

but now i'm trying move a rectangle in this panel,when doing this the transparency goes and the panel goes to it normal back color. any one having an idea how to solve this

i'm using this panel to because under this panel there is another panel that contains a screen shot,so when i'm moving the rectangle in the transparent panel, use sees it as in the 2nd panel.
