I mean, I have a program that will change the color of a certain filename . See for example, I have test.doc in my drive C:\ "C:\test.doc", then I want to change it's properties "I mean the color of the filename (it's default name is BLACK.as what I've observe)."

Do you mean in windows explorer ? If this is possible at all, it would involve some sort of shell extension, probably best written in C++

Yeah, I though it, but it is possible to write it in C# language? Do you have any such idea (I mean, some code that give me some idea to how to?).
Thank in advance.

It's possible, but only by burying yourself in writing a ton of COM Interop code. This is not something you going to get any information on in a forum post since the topic could write an entire book.
Save yourself the overhead and write it in C++.

Hi
I am copying Files and folders from one drive to another using loop.
My problem is that when i copy it also copies system files and folders.
Is there any method or condition to skip them?
Thanks in advance

You can use the FileInfo class to first work out which are system files.

In the properties of the text box, there is a property named Password character : you just keep any symbol or anything on that..
TextBox txt = new TextBox();
txt.PasswordChar = new Char() {'*'};
txt.Text = "Hello";
This might work fine. .

I think you didn,t understand my problem

Hi there
Im a coding newbie and i'd like to find out how to edit cells in a datagridview control and write this back to a database.
To populate the datagridview, i'm using the sqldatareader object.
Any examples would be very much appreciated!!
Thanks

Try a search, there are literally 1000s of article/samples available. There is an excellent one on CP that should be easy to find.
You should do some research on using a datareader, I believe it locks the connection while it is active, therefore you will not be able to use the connection while the grid is active. Use a datatable instead.
Never underestimate the power of human stupidity

to set value in a cell, you must know its column index as well as row index.
dataGridView1[ColumnIndex, RowIndex].Value = "Myvalue";

Dude. ..
Its better not to use a SqlDataReader object. as it locks the connection, and it requires you to keep it open.
You can use SqlDataAdapter and fill the table in datatable. And bind datagridview datasource to that table.
e.g:
SqlConnection cn = new SqlConnection("Bla Bla");
SqlDataAdapter adp = new SqlDataAdapter("Select * from Products",cn);
DataTable dt = new DataTable();
adp.Fill(dt);
datagridview1.DataSource = dt;
The changes you make on gridview cell will automatically be reflected on to the table..
So no worry on that .. .

Hi,
I have recently invested in a security system for my house using low lux colour/infrared CCTV camera's and an internal 8 channel DVR card (T-S808R) for my pc.
The DVR card uses the Philips SAA7130 chipset to encode the video, and has 8 registered devices in the Device Manager. They are registered as "DVR Video recoding device", device type "Sound, video and game controllers" and manufacturer "SAA7130".
Since the Philips chipset should be standard, I recon I should be able to read directly from the hardware driver, however I am unsure of how to do this.
Another way would be to intercept the MPEG4 video file that is created on motion (there is less than 1 second delay) and to interpret this video file, however I am unable to read the file (using a framework like the Tao Framework) to extract individual frames.
Can anybody please give me some advice, preferrably to read from the video driver, that could guide me to getting at the actual frames of the images for possible image recognition functions.
Thanks in advance

I am trying to write a shell extension in C#, which shows an item in right-click context menu in explorer. But all examples which I try contain a lot of code and doesn't show anything (i assume I do something wrong, or don't do some important step  )
Many examples have static methods:
[System.Runtime.InteropServices.ComRegisterFunctionAttribute()]
static void RegisterServer(String str1)
[System.Runtime.InteropServices.ComUnregisterFunctionAttribute()]
static void UnregisterServer(String str1)
Should i call them, or they will be called automatically?
Does anyone have any ideas, or maybe knows any libraries/classes for that, where I can just call something like *.RegisterContextMenu(myMenu).. and ready ?

I am trying to read an Excel sheet to my program using OleDbDataAdapter into datatable , this is working fine except that if the excel column is text and taken into string field in the datatable its read as blank . anyone came across such a case .
I am using ,NET 2.o framework with visual studio 2005 - C# .
thankx

Actually , if the first data cell in the column is numeric , the full column is read as numeric and any text in the same column is read as blank .
and if the first data cell is text then the full column is read as text and any numeric cell in the same column is read as blank .
I have columns with mixed data , some numeric only and some are string .
any hints ?

In fact by default it ooks at the first 8 rows (odd number, really) and decides by that. Its a right pain, the last time I had this problem I ended up converting to csv and reading that.

If an instance of an object subscribes to a static event, even if the instance goes out of scope it remains 'alive' which could potentially cause serious memory problems.
Obviously, the subscriber unregistering itself from the delegate's invocation list solves this, but is there anyway to do this from the class with the event rather than relying on the subscriber over which we may not have control (if we're not writing that code)?
I rarely use static events, this is more out of academic interest.
DaveBTW, in software, hope and pray is not a viable strategy. (Luc Pattyn)Visual Basic is not used by normal people so we're not covering it here. (Uncyclopedia)

Maybe if you override the add of the static event and use a weak reference to store the delegate?
If that's even possible

I've just found a great article[^] on weak events. Some after dinner study there.
