Thats a nasty set of requirements, I suggest you post some reasonable explanation why you need to TAKE OVER your users machine.

There are also Kiosk type applications[^] that may beet your needs

Im taking my own machine... Basically, I need to allow multiple mouse, but since windows wouldnt allow this normally, so Im thinking of writing an application (fully transparent) which be able to track the mouse movement/block input so that I can draw another fake pointer to act as second mouse... Not sure if this make much sense??

You may be able to cheat and use:

<s>SELECT * FROM WEBINFO Where REVERSE(filename) like '%pdf'</s>

Fixed that

SELECT * FROM WEBINFO Where REVERSE(filename) like 'fdp%'

what are the assemblies required for c# BHO to run in all environment?

I had a BHO.
When a web page is opened on IE, I try to replace the HTMLElement's text using

foreach (IHTMLElement HtmlElemen in (IHTMLElementCollection)document.body.all)
{
try
{
HtmlElemen.GetType().GetProperty("innerText").SetValue(HtmlElemen, "NewText", null);
}
catch(Exception e)
{
System.Windows.Forms.MessageBox.Show("Message:" + e.Message );
}
}

In some PC's the html element's text is replaced successfully with "Newtext",
but in some PC's it is not replacing.

And an exception message is obtained "Object reference not set to an instance of an object. "

How to fix this exception?

foreach (IHTMLElement HtmlElemen in (IHTMLElementCollection)document.body.all)
{
try
{
Type type =HtmlElemen.GetType();
if(type !=null)
{
type.GetProperty("innerText").SetValue(HtmlElemen, "NewText", null);
}

// same way check Innertext also has not null reference then set value to taht.
}
catch(Exception e)
{
System.Windows.Forms.MessageBox.Show("Message:" + e.Message );
}
}

If I try this code , a message(exception ) is obtained.
Message:Exception has been thrown by the target of an invocation.

I think, I was missing some assembly, what is it to get executed.

May anyone help?

Hi,

I don't think this is a problem with a missing assembly. As you already mentioned you should check wether the innerText-Property is set or not.

Do this by:

if(null != type) {
   if(null != type.GetProperty("innerText")) {
      ...
   }
}

That should fix the problem.

Sebastian

InnerText is not set, as I try to set the value it throws an exception.
How to fix, Can you explain with some code?

No it is not that InnerText is not set, it is that the Property "InnerText" for the object does not exists. You are using reflection to get the type of your htmlelement and it is possible that this type does not provide an InnerText-Property. There is nothing to fix, you only have to pay attention to this by using the code I provided before.

yes, the only difference is in the PC which has visualStudio, it is successfully sets the innerText Value of an HTMLElement.

I don't understand where I'm doing wrong?

Is it possible, that you could post a bit more of your code, e.g. the point where you get the elements from etc. Maybe this will guide us to the point of failure...

My BHO is build from the code of following link:
How to attach to Browser Helper Object (BHO) with C# in two minutes[^]

Instead of DocumentCompleteEvent I do all this replacement of innerText in a progresschangeEvent.
That's all, remaining thing is what I had posted upto now.

I was using vs2005.

Hi I make any File in PC, and I transfer him to PPC (Windows mobile)
How I can get the Modified date of this file ?
I try this:

DateTime GG;
FileInfo H = new FileInfo(@"c:\License.txt");
GG = H.CreationTime;
GG = H.LastWriteTime;
GG = File.GetCreationTime(@"c:\License.txt");
GG = File.GetLastAccessTime(@"c:\License.txt");
GG = File.GetLastWriteTime(@"c:\License.txt");

but I always get the Today date and time

thank's in advance

Yes the output is correct!!
because you have transferred the file only today!!! so that is the latest write time!!!

That is quite difficult to do AFAIK!

You can try implement this logic with the corresponding code!

1.Before File Transfer operation to your mobile device
--------------> copy the present Created Time, LastWrite time and lastAccess time to a temporary variable!

2.Copy the File!

3.And reset the Created Time, LastWrite Time and LastAccess Time from your temporary variable! since these are properties, you can able to set them! i believe!!!

So if your copy function performs all this three steps, then you will always get the creation date of file as same as your computer!!!!

It may work!!!

Have a Happy Coding.....

code 4 random number without repeating number in a row .

pls, i need code that will generate numbers,from 1 to 40 per row without repeatition.
It must generate the numbers without repeating any number in a row and any row must not repeat it self in the table. so it will generate all possible numbers per rows,in such a way that if i write down numbers 1 to 40 numbers randomly without reapeting any number row, i must find it in the one i generate from the winform gui and C# code.And another button will be able to print preview the table.
[confused]

thanks for ur assistance.

Winforms has nothing to do with it.

The way to get a sequence without repeats is, you fill a list with the numbers 1-40. Then you use a random number generator to pick a number out of that sequence. Then you remove thant number. So, the second time, you need a number between 0 and 38 ( because the sequence is 0 indexed ). So, every time you generate a result, you remove it from the possible result pool.
