You would take a screenshot of the actual desktop, and then chop it based on the box the user drags.

If it already exists; why?

Are you sure it's not enumerating the processes on the system and then capturing their windows?

How to set an item in a object's property(of array type) using Reflection

Hi All,

I have a class named "C1" which has a property name "P1", which is declared as below in class.

Class C1
{
...
Account1[] P1;// Here Account1 is another class/type
...
}

Now i have created an object of "C1" using reflection as below.

// object
Type objTempType = Type.GetType("C1");
object objTempObject = Activator.CreateInstance(objTempType);

Now i want to set value of first item in "P1" property(An array property) of objTempObject using reflection, which i can do without reflection as per below.

objTempType.P1[0].SomeFieldinAccount1Class = SomeObjectOrValue;

Could any one of you please give me some direction on how is that possible.

I checked all the possible ways do it using property/reflection related classes in C#, also searched many sites and forums to get answer but without any success...

Hi
Before you can set the SomeFieldinAccount1Class property/field value you need to intialize / create the element at position 0

objTempType.P1[0] = new Account1();

Hello nissims,

Thanks for your reply.

i have already created the first item in P1[0](before i try setvalue thing), I just didn't want to make my post a more lengthier one, so made the code hide.

You can use the Array class when operating on array properties with reflection.

Using only refection, what you want to achieve is done like this:

Type objTempType = Type.GetType("C1");
object objTempObject = Activator.CreateInstance(objTempType);

PropertyInfo p1Property = objTempType.GetProperty("P1");
Array p1ArrayValue = p1Property.GetValue(objTempObject, null) as Array;

Type itemType = p1ArrayValue.GetType().GetElementType();
object itemValue = p1ArrayValue.GetValue(0);

PropertyInfo someFieldProperty = itemType.GetProperty("SomeFieldinAccount1Class");
someFieldProperty.SetValue(itemValue, SomeObjectOrValue, null);

How to get item clicked event for ContextMenus Dropdown item clicked

<br />
ToolStripMenuItem firstItem = new ToolStripMenuItem("level1);<br />
     for (int i = 0; i<CenterTables.Length; i++)<br />
      {<br />
        ToolStripMenuItem subItem = new ToolStripMenuItem(CenterTables[i]);<br />
         firstItem.DropDownItems.Add(subItem);<br />
      }<br />
      contextMenuStrip1.Items.Add(firstItem);

in the above code centertable is a string array. I am adding the element of this array as sub menu/dropdown item for level1.

Now I need the following task:
1. No need to get the level1 selected item
2. need to handle the submenu seleted event
2. Need to get the sub menu/ dropdownitems that have been selected

How can I do that...

1st.:
Don't add event on top level item

2nd:
Yust add event handler for each sub menu

ToolStripMenuItem subItem = new ToolStripMenuItem(CenterTables[i]);
subItem.Click += new System.EventHandler(subItem_Click);
firstItem.DropDownItems.Add(subItem);

Also there is no Select Event, but Click.

3rd: You can get item in Event Handelr

This code is in event handler and gets ToolStripMenuItem from Object that is passet into event handler. So every SubItem with a can use same event handler and can be distinguished betwen them

ToolStripMenuItem mnu = sender as ToolStripMenuItem;

Hi all,

I am searching the Internet for articles on how to query exchange server 2003, without any result.... Can anyone perhaps provide me with a starting point? Struggling to get out of the block Sigh | :sigh:

More specific ... query the appointment items on a specific mailbox

Many thanks in advance.

Hi all,

Well I found an example: here[^], but I keep receiving an exception, more specifically:

On this line of code: WebDavResponse = (System.Net.HttpWebResponse)WebDavRequest.GetResponse();
Exception: WebException
Description: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.

Any ideas how I can fix this?

Many thanks again.

When requesting to https, you need to add a certificate with the request. Add that to ClientCertificates collection of request object.

To query exchange server and get all mails from inbox, you could do something like

string serverUrl = "https://yourdomain.com/exchange/userid/inbox/"
const string xml = "<?xml version='1.0'?>" +
        "<g:searchrequest xmlns:g='DAV:'>" +
        "<g:sql>{0}</g:sql>" +
        "</g:searchrequest>";

string query = "SELECT * FROM SCOPE('SHALLOW TRAVERSAL OF \"" + serverUrl + "\"') " + "WHERE \"DAV:isfolder\" = false";
string requestString = string.Format(xml, query);

WebHeaderCollection headers = new WebHeaderCollection();
headers.Set("Pragma", "no-cache");
headers.Set("Translate", "f");
headers.Set("Depth", "0");

WebDavRequest.Method should be SEARCH. Set the WebHeaderCollection to WebDavRequest.Headers property.

I have written a useful WEBDAV wrapper for one of our application. I can share as an article later Smile | :)

Hi Navaneeth,

Now I keep receiving the following error message, could it be that the WebDav is disabled on the exchange server?

The remote server returned an error: (440) Login Timeout.

Thanks again.

Not sure. I haven't experienced this so far. All I can suggest is to try adding more timeout value.

ErrorProvider SetError string constraint

Hi,

I am facing an issue when using ErrorProvider's SetError method.
It seems the character "&" is not displayed in the error description string.

<br />
string tempStr = "Input can not contain the characters: &,^,!";<br />
this.mainErrorProvider.SetError(this.inputTxtBox, tempStr);<br />

The above code displays the tool tip consisting of the provided string but the "&" character seems to be converted to "space" character.

I am using Visual Studio 2008 with project targeted for .NET 3.0 Framework.
Any help would be appreciated.
Thanks,

sysdeamon.
