hi there
thanks for the reply
I have built a programmer that i need to test. It uses the serial interface. my project includes me to build a programmer and create the software package. I am still trying to test my programmer but am confused on where to start with programming my software package. Do you have any ideas where i can start?
thanks

Do you know how your programmer works, that is, what you need to do to the serial interface on it to program a chip in the programmer? This might include holding a particular line (DTR etc) high while transmitting data in a particular format.
I don't know how mine works (since I have software that came with it), but I could find out if I needed to by connecting to another PC and monitoring the signals.
As a first stage, you need to investigate what you can and can't do from the CLR to talk to the serial port h/w in your PC.

I am using normal File.Copy method to copy files from remote servers to my local hard drive for processing them.
The issue is file.copy is not reliable and also system gets hanged many time while copying over the network.
so I have decided to use Robocopy (FTP cannot be used because of security reasons)
As it is a command line utility Can anybody help me in how can I use it in my C# progamme without using command line.

Hi,
To start a process use the function:
System.Diagnostics.Process.Start();
This function has a couple of overloads providing different kinds of options.

Use Powershell. Google "C# Powershell". If you are a big command line fan and use C# then Powershell is your best friend.

Hi all!
I know this sounds lazy but can someone please explain to me what REGEX actually does? I mean I've read some tutorials but REGEX was vaguely explained and besides I'd rather learn its actual uses coming from experienced programers rather than text book explanations
Thanks for all your posts! Its greatly appreciated!

simply put, regular expressions are used to parse text data or determine if a particular sequence of characters are contained in a string.
It is a very powerful sub-language used for many many tasks.

Regex or Regular Expression is Designed to Solve Some Problem Like
1-Search and Replace text
2-Validate Text By Pattern
3-Parse Text
So Regular Expression is String Pattern That Used To Manipulate text
So How its Work?
Regx have special characters that you can use them to Create pattern that will be proccessed by regx and get the result
The charachter represnt many type you need to search for Like char,num,white spaceand the repitition of all of this
Some of this Chars are
\d match Any digit
\D match Any nondigit
\s match Any whitespace character
\SW match Any nonwhitespace
. match Any character except newline
* match 0 or more characters
+ match 1 or more characters
? match 0 or 1 characters
{n}match n characters
For examle if you have string like this "Codeproject is great site"
if you want to match codeproject but you forget its name is it codeproject or codesource or any thing like that you
may write pattern like the following
Code.
this will match codeproject
this a brief info about regx its a large topic you will find here at codeproject articles and tools that will help you Yo understand it

Regular expressions are used to match text patterns. Like * and ? in DOS, or like % and _ in SQL LIKE, only much more powerful.

I have an UserControl in the main form. This UserControl contains Panel and this panel contains PictureBox.
I've tried to use this event handler: PictureBoxOnMouseEnter. This handler changes mouse cursor into cross.
It's simple, but when cursor enters the area, it changes for one nanosecond, and then turns back into arrow. Why? Panel, UserControl and even the main forms don't contain any mouse event handlers. There's no code for changing mouse cursor into arrow, but it changes spontaneously. 
Now I discovered that I'm not able to handle MouseWheel events of that PictureBox. And - of course - Panel, UserControl and Form don't work with mouse wheel at all.

Could someone please give me an example in c# on capturing the right click and paste mouse events from any forms/applications. I can capture/monitor this using the keyboard but cannot do so when using mouse cut/copy and paste. Need help please.
I looked at the Globalhooksdemo (project in code project) in c# but only helped me on keyboard cut/copy and paste.
Thanks in advance

There are no mouse messages for that. They are normal, non-input based, window messages. See WM_PASTE[^], WM_CUT[^], and WM_COPY[^].
You'll have to use either the WM_CALLWNDPROC hook or the WH_GETMESSAGE hook to capture these messages. I don't know which because I've never used them myself.

Hi there!
Right click on your datagrid on your designer then click property builder. Click on the columns tab you'l see there what buttons to add and whether its a link button or push button.
Hope that helps! Gudluck!

//MessageBox.Show(this.gDataGrid1[gDataGrid1.CurrentCell.RowNumber,0].ToString());
if(this.gDataGrid1[gDataGrid1.CurrentCell.RowNumber,0].ToString()!="")
{
this.m_iesd = IESDFAC.GetDataByCode(this.gDataGrid1[gDataGrid1.CurrentCell.RowNumber,0].ToString());
this.gDataGrid1[gDataGrid1.CurrentCell.RowNumber, 1] = m_iesd.desc.ToString();
this.gDataGrid1[gDataGrid1.CurrentCell.RowNumber, 2] = m_iesd.remark.ToString();
this.gDataGrid1[gDataGrid1.CurrentCell.RowNumber, 3] = m_iesd.tmu.ToString();

Hi Guys and Gals!!!
I need to show data in a column style, of which two columns are CheckBox-es.
Since ListView doesn't support more than one CheckBox, I've decided to use
a DataGrid for this task.
My problem is that I also need to disable some of the CheckBox-es. Sometimes,
even one of the two on the same row. I could not find a way to get access to
the CheckBox itself in the DataGridBoolColumn. 
I did use one of the examples on this site in order to paint my own CheckBox,
so that when the cell is selected, a real CheckBox appears insted. But I do
have some difficulties with that like bad refresh when the DataSet is changed
of bad response to mouse event and so on and forth...  
CAN ANYONE HELP ME WITH A WORKING CHECKBOX COLUNM ?!?!?!?!??!?!
Thank you all in advance,
Adam Crowe

I apologize for not mentioning this before, but my question regards to WinForms and not ASP.NET.
Thank you.

Is there a way to adjust the height of the rows in a listview? It seems that the function GetItemRect gets called when painting the control but it's not virtual so I can't override it. Will I have to do all the painting myself?
Thanks,
Rob Tomson

Hi Folks,
I just was experimenting with customizing the MenuItem class to suit my needs. I have introduced an accessor method which handles an additional string variable in my inherited class called PJMenuItem.
PJMenuItem pjmi = new PJMenuItem();
pjmi.ExtraInfo = "c:\\temp\\";
pjmi.Text = "HelloWorld";
cm.MenuItems.Add(pjmi.Text,new System.EventHandler(LaunchAction));
Now the problem becomes that each time the menuitem gets invoked via the LaunchAction event handler an exception message gets thrown. Stating that the specified cast is invalid. The event handler is defined as
private void LaunchAction(object sender, System.EventArgs e)
{
try
{
PJMenuItem pjmi = (PJMenuItem) sender;
MessageBox.Show(pjmi.ExtraInfo.ToString());
}
catch(System.Exception ee)
{
MessageBox.Show(ee.ToString());
}
}
Can anyone please tell me how I can overcome this exception error ???
thanks

You're using the wrong overload of the Add method. Passing a string as the frst parameter causes a new MenuItem to be created for you, with the supplied text as the caption and the specified handler. You need to specify the handler in your PJMenuItem constructor (and pass it to the base class constructor) then used the version of the Add method that takes a reference to the menuitem.

g'day Rob
Would it be possible for you to give me another example of your explanation as I am unable to follow through. The point I am having difficulty is with the part where you said i need to specify the event handler in the constructor and then passing it to the base class constructor.
I am refering to the following article on msdn about base class constructors:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/csref/html/vclrfbasepg.asp
But I cant seem to draw a correlation between the msdn article and your explanation.
I would really appreciate it if you could give me another example.
thanks.
