Those parameters are not declared or initialized anywhere in the code you posted. Since the method is static I would hold them highly suspect.
Also you are doing nothing in the code you posted to verify a valid FilePath

Hi All,
I m using the infragistics ultraChart to show some data.
The problem is that the values on the X line, wil show automatically in decimal format. How can i change this to integers?
Thanx.

In C/C++, we may code:
union aa {
double bb;
char cc[8];
} a;
In this way we may verify the actual data stored in memory for the double. How do I do that in C#?
Thanks.

Does this [^] help (see Attributes on Structs paragraph at the bottom of the page)?

No, documentation is not helpful.
Well at least to those who refuse to read it. Yet somehow reading the same information in a forum post is helpful, go figure.

It really helps, thanks a lot.
Seems it doesn't take arrays as follow:
using System.Runtime.InteropServices;
[StructLayout(LayoutKind.Explicit)]
struct TestUnion
{
[FieldOffset(0)]
public double d;
[FieldOffset(0)]
public char[] c;
}
workaround would be:
[StructLayout(LayoutKind.Explicit)]
struct TestUnion
{
[FieldOffset(0)]
public double d;
[FieldOffset(0)]
public char c0;
[FieldOffset(2)]
public char c1;
[FieldOffset(4)]
public char c2;
[FieldOffset(6)]
public char c3;
}

Yes. I guess it is because arrays are allocated on the heap.

Yes, but not in the same way. You need to use the StructLayout and FieldOffset attributes on the struct and fields, respectively. For your example, the equivalent in C# would be
[StructLayout(LayoutKind.Explicit)]
struct aa
{
[FieldOffset(0)]
public double bb;
[FieldOffset(0)]
char[] cc;
}

Hi,
I need to build a application where I have a mainform and multiple runtime generated forms.
There are many good methods to pass data between 2 winforms but I have a problem to get it work with runtime generated forms.
Is there someone who have a simple sample where i can start from.
Thanks

I don't quite understand what you mean. What is the difference between a "winform" and a "runtime generated form"?
|
|
|
|
|
Sorry,with a winform I mean a standard form
|
|
|
|
|
What is a "standard form"? You have to explain what you mean by both things because I still don't know what you mean.
|

Hi Colin,
A Standard form is just a form you make with the interface from Visual Studio(the basic Form1.cs in a new solution for example).
The runtime form is a form that I totaly create from code when i hit a button.
private void button2_Click(object sender, EventArgs e)
{
Form frmRuntime = new Form();
frmRuntime.Show();
}
In realtime i have a form frmMain with a couple of buttons. Each button opens a form that is not visible in my solution explorer but is generated 100% from code. The problem is that I want pass de data (textboxes) from the code generated form to the main form (frmMain).

They will be somewhere in the Controls collection? So long as you have uniquely identified them (use the Name property), you can use the Find method on the ControlCollection
For example:
myForm.Controls.Find("MyTextBox");
NOTE: The above line of code will return an array of Control objects because it is possible to have multiple controls with the same name.

When I try to add the generated dll file, the visual studio didn't accept the dll file..
plz reply asap..
thnx in advance..
code for dll
--------------
#include <stdio.h>
extern "C"
{
__declspec(dllexport) void DisplayHelloFromDLL()
{
printf ("Hello from DLL !\n");
}
}
___________________________________________________________
code for C# program
--------------------
class HelloWorld
{
[DllImport("TestLib.dll")]
public static extern void DisplayHelloFromDLL ();
static void Main ()
{
Console.WriteLine ("This is C# program");
DisplayHelloFromDLL ();
}
}

Everything looks ok, are you sure the dll is where your program can find it? Also, you do not add it as a reference like normal .NET assemblies.
|
|
|
|
|
Perhaps your exports aren't correct. Try adding them explicitely to your .def file.

Hi
I have an enumerated type that has two elements : fixed and floating, but I can't use "fixed" because it is an identifier.
Any ideas how I get around this?
|
|
|
|
|
If you want to use a reserved word for that kind of thing you need to put an @ in front of it
enum MyEnumeration
{
@fixed,
floating
}
...
Console.WriteLine(MyEnumeration.@fixed.ToString());
