I want to be able to trigger a button on the form from within the DataGrid with the Enter Button.
The variables are already in the proper places upon any change in the cell, .. so I just need to be able to capture Enter, and have it trigger a button.

i believe its the OnPreviewKeyMessage. You have to override it on the column
I'm not an expert yet, but I play one at work. Yeah and here too.

I'm new to xml docs, and I'm trying to use a third
party .NET lib that came with an xml doc file... would
like to be able to access the help but can't find info on
how to do this...
I've added the project to my solution, and I've verified
that the xml file exists in the location specified by the
projects output dir... built the solution but nothing
appears in dynamic help for the project/lib...
What am I doing wrong..???
thanks for any help..

The XML documentation generated by the compiler must be parsed by tools such as NDoc (which I help develop). To integrate the help into VS.NET, you actually have to do quite a bit of work that involves the Help 2 system. You can find more information on MSDN by searching for "VSHIK", the Visual Studio Help Integration Kit.
As far as "tooltip help" when you're typing in the VS.NET source window, the XML file for the assembly merely has to be in the same directory as the assembly itself. VS.NET will see that XML file and show the appropriate help based on what you're typing (class, method, parameter, property, etc.). It will not automatically integrate this into the help system (dynamic help, table of contents, index, and search), however.

What exact arguments do I need to send to this btnNew button to be triggered from the "clickBtnFromMethod()" ?
private void btnNew_Click(object sender, System.EventArgs e)
{
MessageBox.Show("New Clicked","New");
}
private void ClickBtnFromMethod()
{
btnNew_Click();
}
|
|
|
|
|
presuming your button is called btnNew:-
btnNew_Click(this.btnNew, EventArgs.Empty);

As I am new to C# programming I was wondering if you could help me. Attached is a xml file that I am simple trying to display in a grid control on a Windows form program. Unfortunately I keep getting the following error
An unhandled exception of type 'System.ArgumentException' occurred in system.windows.forms.dll
Additional information: Cannot create a child list for field fegdata.
Here is the code im using when a button is clicked.
DataSet dsFeg = new DataSet("fegdata");
string filepath = "C:\\FegData.xml";
dsFeg.ReadXml(filepath);
dataGrid1.DataSource = dsFeg.Tables[0];
dataGrid1.DataMember = "fegdata";
dataGrid1.CaptionText = dataGrid1.DataMember;
Any help would be greatly appreciated.

Do the following instead, as you have your DataSource set to the table and the DataMember referencing the DataSet name (completely backward):
DataSet ds = new DataSet("fegdata");
ds.ReadXml(@"C:\FegData.xml");
dataGrid1.DataMember = "tableName";
dataGrid1.DataSource = ds;
dataGrid1.CaptionText = ds.DataSetName;

IntPtr is just a data type that has a size of 32bits when running on 32bit hardware and 64bits when running on 64bit hardware.
That just makes it suitable for representing a pointer into memory.

See the System.Runtime.InteropServices.Marshal.Copy() method. It itself is unsafe, but doesn't require you to implement this in an unsafe context. Other than that (implementing the unsafe stuff in another assembly so you can mark your assembly as safe), you would have to pin the address and do it yourself.

Hi,
Does anyone know any free syntax highlighting control for c# windows forms?
Thanks
|
|
|
|
|
You might want to check out SharpDevelop[^]
I think they have a syntax coloring editor, not sure if its specific to c#.
Cheers,

I am declaring a variable holding an object, and a reference to that variable. Like so:
CWhatever oObject = new CWhatever("xyz");
CWhatever oReference = oObject;
Further more, I would like oReference always to refer to the object initially assigned to oObject. In C++ speak and using pointers, this would be something like
CWhatever * const pObject = new CWhatever("xyz");
Note it is not the object that is constant, but the reference.
I fail to find how C# supports such a restriction. Any clues (other than using managed C++)?
TIA,
Bernd

Its only valid at the class level (not the method level) but you can use the readonly keyword on your variable declaration. It will then be a compile error to change the reference outside of the constructor.
[edit]
duh forgot the handy example 
class Test {
private readonly MyClass foo;
public Test()
{
foo = new MyClass();
}
}[/edit]

Hi!
Is there any simple method to detect which Link on linkLabel has been clicked before context menu opening?
I've got linkLabel with context menu set to some contextMenu. When I click LMB, the linkLabel1_LinkClicked event fires ok. But RMB does not fire this - just contextMenu appears, without any info about current link. Any ideas?

if you set the ContextMenu property back to null you should be able to handle the RMB event as you want, then use the ContextMenu's Show method to show the correct context menu.
