<pre>I wrote code to access structre from C# .net where structure is in C dll .when i debug the code i got garbage value in the variables.
here are the two files .
------------------------- StrcutreDisplay.dll---------------------------------
#include<iostream.h>
#include<conio.h>
#include<malloc.h>
#include<string.h>
extern "C"
{
typedef struct
{
char *fname;
char *lname;
}Detail;
__declspec(dllexport) Detail * Disp()
{
Detail *ptr=(Detail *)malloc(sizeof(Detail));
ptr->fname = (char*)malloc(50);
memset(ptr->fname, 0x00, 50);
ptr->lname = (char*)malloc(50);
memset(ptr->lname, 0x00, 50);
strcpy(ptr->fname, "larson");
strcpy(ptr->lname, "scolari");
return ptr;
}
}
----------------------------StructureExample---------------------------------
using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;
namespace StructureExample
{
class Program
{
[StructLayout(LayoutKind.Explicit)]
public struct Detail
{ // [MarshalAs(UnmanagedType.LPStr)]
[FieldOffset (10)]public unsafe char* fname;
[FieldOffset(10)]public unsafe char* lname;
}
// strucure DLL
[DllImport("StructureDisplay.dll")]
public static unsafe extern Detail * Disp();
static void Main(string[] args)
{
unsafe
{
Detail * var = Disp();
char* a = var->fname; //here i get garbage value and the value of this expression may be incorrect.it could not be evaluated because 'Cannot derefrence'(*var).fname' the pointer is not valid.
char* b = var->lname; // 'Cannot derefrence'(*var).lname' the pointer is not valid.
}
// IntPtr por = Disp();
//unsafe
//{
// Detail* ger;
// ger =(Detail )Marshal.PtrToStructure(por,typeof(Detail ));
//}
Console.WriteLine("hello world");
Console.Read();
}
}
}
------------------------------------------------------------------------------------------------
when i access that dll from c it works fine but through .net i get some garbage value.when i tried to convert char * to string by using a method of Marshal class (ptrToStringAuto() or ptrToStringAnsi())that time also i get some garbage value.My main question is why i am getting garbage value in char * a and char * b.
Any help appreciated.
Thanks in advance.</pre>

First, you have set the same field offset for your two members in the struct, which means that they occcupy the same memory area.
Second, you have set the field offset to ten. Why do you think that the structure starts with ten unused bytes?
If you use the fields offsets 0 and 4, it may have a chance to work.
Despite everything, the person most likely to be fooling you next is yourself.

With a description as vague as "doesn't work", it's not very easy to offer any guidance... What happens exactly when you try what I suggested?

hi...
could someone tell me the codes for this scenario..
if i click on the datagridview for example username
if i click that username that username will appear in a label or textbox...
thanks...

you heard something called CellClick even.
Then just get the value of selected cell and giv it to the Text property of your control(Label, TextBox ...)
And don't ask your question twice!!!

sory for asking twice...
i know what your saying but i dont know how to get the value of the selected cell...
can you tell me...
|
|
|
|
|
Try this
tbUserName.Text = gvUsers.SelectedCells[0].Value.ToString();

Try the CellEnter event:
void dataGridView_CellEnter(object sender, DataGridViewCellEventArgs e)
{
if (((DataGridView)sender)[e.ColumnIndex, e.RowIndex].Value != System.DBNull.Value)
Textbox.Text = ((DataGridView)sender)[e.ColumnIndex, e.RowIndex].Value.ToString();
}
