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!

I want the "enter" key to function with my getcode() instead.When i type the code in the code column.pressing enter will display the whole row.
private void GetCode()
{
//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();
this.gDataGrid1[gDataGrid1.CurrentCell.RowNumber, 4] = m_iesd.position.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.

okay, here it is. i have this
as my opengl window, on load, and this image i need to draw fullscreen. basically the code looks like this:
this.ClientSize = new System.Drawing.Size(640, 480);,
GL.glVertex3f(0f,0f,0f);
GL.glVertex3f(640f,0f,0f);
GL.glVertex3f(640f,480f,0f);
GL.glVertex3f(0f,480f,0f);, and
GL.glOrtho(0,640,0,480,0,1);. as previously stated, i want the image to be drawn in the exact amount of pixels that it came with. in case pointers arent enough and a whole source fix is needed, the source for tyhe entire program can be found here. thanks for your time

Rob,
EXACTLY what my App needed.Didn't even know there was such a thing as
"current culture". Many thanks.....
|
|
|
|
|
If you ever intend to write applications that might be used outside your country, you should read up on the CultureInfo[^]and System.Globalization [^] Name space. Most of the string formatting and comparison functions in .NET have overloads that expect culture specific parameters, and it is generally recommended that you use these to get predicatable results in all languages.
