Hello,
I'm working on a Mapi Agent using C#.
Everything works fine despite the fact I've to commit the nice Outlook Message
which is shown after Installing the Security Update for Microsoft if you try to send mails from other interfaces.
See the Knowledge Base Articel :
http://support.microsoft.com/default.aspx?scid=kb;en-us;263073
WD2000: Warning Message: "A Program Is Trying to Access ..." When You Send Mail Merge to E-mail After You Apply Outlook Security Update
and Information for Developers :
OL98: Developer Information About the Outlook E-mail Security Update
http://support.microsoft.com/default.aspx?scid=kb;EN-US;262700
The Problem is that I've to commit this windows automatically - because this agent should run by itself.
I already find out that I've to use the user32.dll with their functions FindWindow and SendMessage,
and that you have to use Spy++ to find out the WindowClass and the wParam and lParam in hex formate.
Indeed I'm right now at the point that I can find the window, and can send messages - WM_Command.
But the wNotifyCode is wrong, I've to send a BN_Clicked WM_Command but with my routine I send a Code 0 (send from a menue) to the Window
although I got the right hex codes.
So now my question : how can I send a BN_Clicked Message to the window?
Is there any other opportunity to commit the windows with "Yes"?
I'm grateful for any advice.
Here are some code snippets :
----------------------------------------------------------------------------------
The class for the user32.dll Import and their functions :
----------------------------------------------------------------------------------
public class Win32
{
public const int WM_COMMAND = 0x111;
[DllImport("User32.dll")]
public static extern int FindWindow(string strClassName, string strWindowName);
[DllImport("User32.dll")]
public static extern int FindWindowEx(int hwndParent, int hwndChildAfter, string strClassName, string strWindowName);
[DllImport("User32.dll")]
public static extern Int32 SendMessage(
int hWnd, // handle to destination window
int Msg, // message
int wParam, // first message parameter
[MarshalAs(UnmanagedType.LPStr)] string lParam); // second message parameter
[DllImport("User32.dll")]
public static extern Int32 SendMessage(
int hWnd, // handle to destination window
int Msg, // message
int wParam, // first message parameter
int lParam); // second message parameter
}
----------------------------------------------------------------------------------
----------------------------------------------------------------------------------
The Main Routine with the calling routines :
----------------------------------------------------------------------------------
System.Int32 iHandle
// Finding the window :
iHandle = Win32.FindWindow("#32770", "Microsoft Office Outlook");
// Send a Message
Win32.SendMessage(iHandle, Win32.WM_COMMAND, 0x000012A6, 0)

Hello,
i have developed a web service where the client sends to the server a signed xml document signed with "Infopath". When the server receives the document it is impossible fot him to valiadate the signatures. Here is my code:
(doc is a XmlDocument)
<br />
XmlNodeList nodeList = doc.GetElementsByTagName("Signature");<br />
SignedXml[] signatures = new SignedXml[nodeList.Count];<br />
<br />
for(int i = 0; i < nodeList.Count; i++)<br />
{ <br />
signatures[i] = new SignedXml();<br />
signatures[i].LoadXml((XmlElement)nodeList[i]);<br />
if (!signatures[i].CheckSignature())<br />
validSignatures--;<br />
}<br />
The xml document has been signed with a valid X509 certificate.
thank you for your help!

Hi,
I have different user controls associated with the tree nodes using 'tag' property, I want to display the user controls in the empty area in the form that contains the tree view control. Can any one please guide me how to access the user control using the tag property in the AfterSelect event of the tree view control?
|
|
|
|
|
You can cast the sender as a TreeNode object and then access it's properties directly. This will allow you to see what the Tag value is.
private void treeview1_AfterSelect(object sender, TreeViewEventArgs e)
{
TreeNode node = sender as TreeNode;
if(node != null)
{
}
}

I have done this, but still not able to access the original user control.
Let me explain again what I am doing
private void LinkUserControls()
{
treeview1.Nodes[0].Tag = _myUserControl;
}
private void treeview1_AfterSelect(object sender, TreeViewEventArgs e)
{
TreeNode node = e.Node;
if(node != null)
{
// i would like to make _myUserControl visible here.
// like
_myUserControl.visible = true;
_myUserControl.location = new System.Drawing.Point(50,50)
}
}
please guide

got the solution it worked as follows
private void treeview1_AfterSelect(object sender, TreeViewEventArgs e)
{
if(e.Node != null)
{
UserControl uc = (UserControl) e.Node.Tag;
uc.Visible = true;
uc.BringToFront();
uc.Location = new Point(225, 240);
}
}

How can I get a variable pointer (as IntPtr) ?
I am trying to compare between two objects, the objects are not the same but they could be from some place ...
Example - let say we have two classes one derived from another ...
public class A
{
protected h=0;
public virtual func()
{
h=0;
}
}
public class B:A
{
public override func()
{
h=1;
}
}
Now ... I'am creating the objects ...
obj1=Activator.CreateInstance(t1); //Type t1; class A
c.Invoke(obj1,null); //ConstructorInfo c; getting constructor from class A
the same with the other class...
obj1=Activator.CreateInstance(t2); //Type t2; class B
c.Invoke(obj2,null); //ConstructorInfo c; getting constructor from class B
From this point you can see in the debugger obj1,obj2 (with the variable h=0 in both)
Now I'am invoking my function...
//MethodInfo m1,m2; getting my virtual AND override functions each from it's class ... and after that running functions , with null as parametter...
object []parametersForFunction=new object[m1.GetParameters().Length];
//m1 or m2 doesn't matter they have the same parameters... virtual,override
m1.Invoke(obj1,parametersForFunction);
m2.Invoke(obj2,parametersForFunction);
I can't check "h" with the GetFields() couse its not public()..
My problem is here...
Now if wee go back to the debugger we can see that in obj1.h=0 and obj2.h=1
Somthing like this
obj1.A.h=0
obj2.B.A.h=1
My idea was to try the Marshal.ReadIntPtr(IntPtr,offset) so I can read obj2 after some offset, So I needed my variable Address. (somehow even in unsafe we cant do object *p=obj1; on objetcs...)
I tried Marshel.ReadByte and it's not working cause my object type could be anything...
Anyone have some idea ???
Thanks

You can use BindingFlags to get non-public members from an object.
Type.GetField(name, BindingFlags.GetField | BindingFlags.NonPublic)
|
|
|
|
|
Yes, but I still wanted to do this by comparing objects.
I want to know how to get a variable pointer as IntPtr and how to read from unknown type object from a specific place.

I don't think the framework would allow you to do that. You could mess up all the class info stuff including vtable. Plus you would have to know internal layout of the class data structure, and that might be system dependend (might work differently on mono or .netgnu)
You can download rotor and see how they lay it out.
If you try to get address of any managed type, you'll get error:
Cannot take the address or size of a variable of a managed type.

Hi Friends
I want to make a spyware. Please suggest me how the available spywares work
please let me know about their functionalities.
Where they check for the files, how they know which program is shareware etc.
Any pointers or help is appreciated.

From what I've seen of them. It is not something I wish to discuss.
softp_vc wrote:

The two big functions they perform are: (1) They irritate users. (2) They steal information.
softp_vc wrote:

Where would you normally check for files? The filesystem perhaps.

Not so sure about the help though. I don't want more spyware out there.

I can't help you with creating something to search for spyware because i wouldn't know where to start but if all you want to do is find out whats on your PC then try downloading SpyBot, it's free and worked well for me.

If any body knows please let me know.
I need the information urgently.

No one is going to help you write spyware, besides C# wouldn't be best suited for this anyway.

I told you, no one is going to help you with something like this. This is a C# forum, if you have a specific C# question please feel free to ask it here.

There are so many different registry keys and values, and so many different files, you'll find it VERY difficult to write your own software without doing a ton of research on the spybots themselves. You can't write an application that will find any and all spyware from the first annoyances that came out to the new ones noone has thought of yet. Your app has to be able to look for signatures, just like virus scanning software does, and must be able to read those signatures from a file. The signatures would include registry information, filename information, data on the procedures the spyware uses, like renaming and replacing of files, even signature information to find spy code in other files.
But, you'll have to do a mountain of research on spyware first. No two spyware's work the exact same way and just searching for simple registry values and filenames will not do you any good. Your software must be able to adapt to the ever techniques of spyware.
Why don't you ask the people who wrote SpyBot...

Hi
I’m looking for same sample c# code that can extract outlook/exchange email attachments from a specified folder to a folder on a file system. I need this to be a client app rather than using exchanges server side event scripting.
Thanks in advance.
