Hi
I have a form that has text boxes and combos bound to fields in an object. When the user is using the form they have the option to apply some default values to some of the fields. I was hoping that I would just have to either update the control with the value or just update the field in the object. When I update the field in the object, the form will not refresh with the new values until another field on the form is changed. If I update the control, the field in the object does not update.
My way around this was to update both like this
case "LOGCERT_LEVEL_":
logginCertCombo.SelectedValue = newValue;
staff.LogCert = newValue;
break;
To me that is a bit ugly 
Is there a way to do this automatically? My controls are bound like this
logginCertCombo.DataBindings.Add("SelectedValue", staff, "LogCert");
I've tried google and today it is not being my friend.
Many Thanks
The FoZ

Sound like you want to look at the .BindingContext for your Form in order to get the BindingManagerBase (which will get you a Property Manager versus a CurrencyManager because it looks like you are binding to a single business object) so that you can use .PullData() and .PushData() to sync your controls and DataSource ...

Thanks for you reply Gerry, but I'm not sure how to get this working. I've looked up the Currency and Property Manager Classes and where the classes contain the Push and Pull methods they are not visible.
I created a private CurrencyManager myFormCurrencyManager for my form and added
myFormCurrencyManager = (CurrencyManager)this.BindingContext[staff] after I bound the controls. This caused an invalid cast exception so I changed it all to a PropertyManager still with no luck.
Am I missing something else? Do you know of any decent examples?
Cheers

Sorry about that; didn't realize those methods were protected.
Here is a solution that works: use the DataBindings ReadValue and WriteValue methods; eg.
<pre>using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace WindowsFormsApplication1 {
public partial class Form1 : Form {
private TextBox fistNameTextBox =
new TextBox() { Location = new Point( 0, 0 ) };
private TextBox lastNameTextBox =
new TextBox() { Location = new Point( 0, 30 ) };
private Button readButtom = new Button() {
Location = new Point( 0, 70 ),
AutoSize = true,
Text = "Read from Source"
};
private Person aPerson = new Person();
public Form1() {
readButtom.Click += new EventHandler( readButtom_Click );
fistNameTextBox.DataBindings.Add( new Binding( "Text", aPerson, "FirstName" ) );
lastNameTextBox.DataBindings.Add( new Binding( "Text", aPerson, "LastName" ) );
this.Controls.AddRange( new Control[] {
fistNameTextBox, lastNameTextBox, readButtom } );
}
void readButtom_Click( object sender, EventArgs e ) {
aPerson.FirstName = "John";
aPerson.LastName = "Smith";
foreach ( Control control in this.FindForm().Controls ) {
if ( control is TextBox && control.DataBindings.Count > 0 )
control.DataBindings[ 0 ].ReadValue();
}
}
[STAThread]
static void Main() {
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault( false );
Application.Run( new Form1() );
}
public class Person {
public string FirstName { get; set; }
public string LastName { get; set; }
}
}
}</pre>

Thanks Gerry.
The foreach loop was exactly the thing I was after
foreach ( Control control in this.FindForm().Controls )
{ if ( control is TextBox && control.DataBindings.Count > 0 )
control.DataBindings[ 0 ].ReadValue(); }
Cheers

Hi Everyone,
I have placed a sample code below in which i need to type cast from struct to list<object>. In this below example how i can add emp1 to operation list
public struct Operation
{
public bool success;
public string msg;
public List<Object> ListTest;
}
public struct Emp
{
public int EmpID;
public string EmpName;
}
public class Class1
{
public Class1()
{
//
// TODO: Add constructor logic here
//
}
public void Method1()
{
Emp emp1 = new Emp();
Operation op = new Operation();
emp1.EmpID = 1;
emp1.EmpName = "Manoj";
op.success = true;
op.msg = "pass";
op.ListTest.Add(emp1);
}
}
Regards,
Manowj

And your problem is?
Looking at it, you are getting a "object not set to an instance of an object" exception, I suspect. Try:
{
Emp emp1 = new Emp();
Operation op = new Operation();
op.ListText = new List<object>();
emp1.EmpID = 1;
emp1.EmpName = "Manoj";
op.success = true;
op.msg = "pass";
op.ListTest.Add(emp1);
}
Or, by preferance, convert it to a class and handle it's internals better yourself!
BTW: use <pre> and </pre> blocks to preserve your formatting in future. It isn't too bad with a tiny fragment like this, but later...

I wouldn't want to convert it to anorexic XML.
Edit your OP to correct the code, and reflect the JSON requirement - you may get a more helpful resonse.

Hello,
I want to read and write in the notepad itself. I can write any text to notepad file but i can't able to read the text. Like if i have opened "sample.txt" file in notepad and i want to read the content of that file. Here is my sample code:
Process notePad = new Process();
notePad.StartInfo.FileName = "notepad.exe";
notePad.StartInfo.Arguments = "C:/Users/krinal/Desktop/1.txt";
notePad.StartInfo.UseShellExecute = false;
notePad.StartInfo.RedirectStandardOutput = true;
notePad.StartInfo.RedirectStandardInput = true;
notePad.Start();
notePad.WaitForInputIdle();
notepadhandle = notePad.MainWindowHandle;
//write text to notepad
SetForegroundWindow(notePad.MainWindowHandle);
SendKeys.SendWait("Testing");
using sendkeys() we can write to notepad, is there anything for reading?
Please help me out.
Thank you in advance.

Try to find the child window whose text you want (by using for example Spy++).
After that use:
int GetWindowText(HWND hWnd, LPTSTR lpString, int nMaxCount);
If this fails, you need to attach your main thread to the notepad ones.

Thank you,
I understand GetWindowText() method but what child window means?
Actually i am developing Text_To_Speech application, need to read notepad content text.
So i think my child window will be notepad. And i get content of notepad and use them from my application.

|

The main wnd is the full window with titlebar, menu, statusbar and so on.
But you need the text from the child edit window.
On my system notepad has the following windows (used spy++):
+ Window 000C0B3E "Unbekannt - Editor" Notepad
|--- Window 001D0848 "" Edit <--- thats the window with the text you want
|--- Window 00140B54 "" msctls_statusbar32

the "dsofile.dll" i have registerd using regsvr32 in command
and the second "Interop.Dsofile.dll" added as refrence in assambly and written some code using classe of the dll.
my doubt is
1.what is the diffrence of these two dll?
2.is it possible to Use the "dsofile.dll" in .net code (i am sure it not possible to add refrence as assably) any other way? and how
please give me some explation.

what about the question is it possible to add all the dll?
if i add like "mshtml.dll" which is in "c:\WINDOWS\system32" it says
"please check wethere the dll is valid assambly or a com component"
is it possible to import the dll as unmanaged dll?
thank You

Dear friend.
thank you for Your reply.
that was good solution for my problem ..... because i was adding another dll called "microsoft.mshtml" which took size of 7MB..
and
stancrm wrote: SHDocVw.dll
do not have windowStateChange event
but if i refer "microsoft.mshtml.dll" i get windowStateChange event. how to go about?
and i take for granted that it is not possible to add all the dll in .net (dll are diffrent 1.com dll 2.net dll and 3 system dll) is it correct?

Although Microsoft chose to have the same extension for these files, there are different "flavors" of dll files.
1. Native dll that has exported funtions - Use DllImport attribute to use functions in these dlls
2. COM dll (aka ActiveX dll) - Use 'add reference' dialog to add reference to these dlls - The VS IDE silently creates a RCW (Runtime Callable Wrapper), that is essentially a .NET Assembly that makes it easy to use your COM dll. This is what has happend in your case (Interop.Dsofile.dll is the RCW for dsofile.dll - you need both files for your app to run).
3. Managed dll (aka .NET Assembly) - These are created by .NET compilers and can be used directly from .NET clients. They can also be used by COM clients using CCW (COM Callable Wrappers).
Uhhh!!! Quite complex, isn't it ?
