Refresh won't work either because his code is not giving up control to allow the application's message pump to process the WM_PAINT messages and call the repaint code.

Refresh() is equivalent to {Invalidate(true); Update();} and the Update() method forces the control to repaint itselft executing any pending WM_PAINT messages bypassing the application queue. Update() is equivalent to the UpdateWindow() function. More info in: http://msdn2.microsoft.com/en-us/library/ms534874.aspx[^].
I might be missing something, but try this code here. It works perfectly if you can bare an unresponsive UI. My label is refreshing perfectly. Its a simple form with a label and a button to start the test:
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
doTest();
}
private void doTest()
{
label1.Text = "Starting Method 1...";
label1.Refresh();
anyMethodCall();
label1.Text = "Starting Method 2...";
label1.Refresh();
anyMethodCall();
label1.Text = "Starting Method 3...";
label1.Refresh();
anyMethodCall();
label1.Text = "Starting Method 4...";
label1.Refresh();
anyMethodCall();
}
private void anyMethodCall()
{
System.Threading.Thread.Sleep(5000);
}
}

Ok, I'm wrong, damn OS being smart and getting in the way 
My app fails to refresh if I try to move the window around.
During the first 2 calls to anyMethodCall() my UI is unresponsive and my label is refreshing perfectly but then the window will start to move perfectly according to my mouse requests even if the app is still executing calls 3 and 4. And whats worse, my label stops refreshing. This is due (I guess) to Windows (Xp in this case, don't know if 2000 or previous work the same way) detecting my window as unresposive and taking action.
DoEvents() will take care of this situation becuase it will inform the OS that my window is once again valid while Refresh() will not do that and the OS will keep on thinking its not responding.
So yeah DoEvents() is the best solution because you can't rely on the user not trying to move the window around. My bad

OK, but that wasn't the point behind using Application.DoEvents(). Try updating 6 or 7 controls during a blocking operation. Now you'e got to call Update on those controls, individually. Mking all the changes then calling Application.DoEvents() let's all those controls repaint themselves all at once, with a single call.

No big deal!  Everything has a purpose, even Refresh!

After you change the Text of the label, you're code doesn't go idle to allow the message pump to process the WM_PAINT message it receives because you changed the label. You need to call Application.DoEvents() to get your code to let the message pump do it's work. This is easily done if you move the code to change the label to a method:
UpdateStatusMessage("Calling method1...");
method1();
UpdateStatusMessage("Calling method2...");
method2();
UpdateStatusMessage("Calling method3...");
method3();
.
.
.
private void UpdateStatusMessage(string message)
{
label1.Text = message;
Application.DoEvents();
}

But the problem is that after starting App. I wish to close that App. through Exit Button, but at that time cursor inside TextBox1 so it execute OnLeave function 1st and then I've to again click on Exit button, But i want when I clike on Exit Button in that case OnLeave function will not execute.
How it is posible if any one know plz reply.
Welcome any tips...
Thanx & Regards

Create a flag and make it false when the user clicks the exit button.
In the onleave function, first check if the flag is true or not.

As U have only
5 controls in Ur form,
better try this:
Create a member as follows:
TextBox LastBox;
For the OnLeave event of 3 textboxes,write like this:
Text1_OnLeave()
{
LastBox=TextBox1;
}
For the OnLeave event of other controls,assign null to the member "LastBox".
Create a function as follows:
=============================
Validate()
{
if(LastText==TextBox1)
{
Code to validate Textbox1.
}
else if(LastText==TextBox2)
{
Code to validate Textbox2.
}
else if(LastText==TextBox3)
{
Code to validate Textbox3.
}
}
Call the "Validate" function in the OnEnter event of all the controls,
except ExitButton.
If U R not able to find a better solution, use this.
Regards,
Arun Kumar.A

1) Don't check string.IsNullOrEmoty condition "if it is not necessary (acceptable for values which may be left empty)" which is "I think" true for your TextBox1 with Default cursor
OR
2) Don't set default cursor on your TextBox1 when the parent Form is activated (Shown, Selected...)
OR
3) update a text changed flag to true in TextBox.TextChanged event and use:
if(_boolTextChanged == true)
{
Validate(); // write your validation code here
}
else
{
return; // The user hasn't done anything, why make him/her crazy, DON'T validate anything!!!
}
4) I prefer validating everything in one function when the user is finished with all modifications and presses for example the Submit Button which does not break down the nerve system of the user hearing a BEEP sound or ToolTip warning if the validation fails for the control he/she is currently modifying.

Hey,
When I use a Culture and a resourceManager but there is no resourcebundle for my culture? What does he do?
And can I automaticly let him determin which resourcebundle he has to take (for example get the country settings of windows XP and use these to set your culture? (Don't know but I think this can)
Thx!

Hi,
For pulling information about a dll, I have tried Assembly.Load("dll name"), it doesn't work and I understand that I need to pass a full name. My requirement doesn't provide the full name, only the name of the dll should be passed and I should get full name with version, culture inforamtion etc.
Can some one tell how to fetch the version, culture etc information when given a dll name which is there in GAC..
Thanks for your help.

What happens? Does it throw an exception? Does it silently do nothing? Crash your hard disk?
I think the method you want is Assembly.LoadFile().

Yes it throws exception..
Assembly LoadedAssembly = Assembly.LoadFile(@"c:\WINDOWS\assembly\mscorlib.dll");
Exception Occured: The system cannot find the file specified. (Exception from HR
ESULT: 0x80070002)
I tried both Load and LoadFile, getting the similar exception. Any clues?
Thanks

The issue that you have here is that there is no file "c:\WINDOWS\assembly\mscorlib.dll". If you go to the command line and type in dir c:\windows\assembly you will see that it lists directories. The version that you see in the Windows shell is a wrapper to make it convenient for managing GAC entries.

Yes, you are correct. Not aware of this point...
But how to find out the info about the dll which are in GAC, (only know the dll name)?
I am really struck here, Thanks for your help.
Satya

If you only know the DLL name, then you should use Assembly.Load(); Here's an example:
Assembly assem = Assembly.Load("mscorlib.dll");

It works only with mscorlib.dll, if you try with some other dlls it fails... I am trying to build an application which needs the full deatils of the dll and it uses this information to generate a binding file.
|

Well, the hack way to do this would be:
Assembly assem = Assembly.Load("mscorlib.dll");
if (assem != null)
{
string path = System.IO.Path.GetDirectoryName(assem.Location);
assem = Assembly.LoadFrom(System.IO.Path.Combine(path, "System.Xml.dll"));
}

In addition to what Pete said... why do you want to load that particular DLL? If you want to look at the contents of mscorlib.dll, I suggest you fire up wincv.exe. If you want to load any DLL, verify the path and use Assembly.LoadFile().
I think relative paths will work with Assembly.LoadFile(), but if it blows up, Path.GetFullPath() is your friend.

Vıkram.

Assembly.Load loads an assembly which is in the same directory with your application's executable.
Try Assembly.LoadFile or Assembly.LoadFrom but then your application can only run in FullTrust for security reasons.

When using Microsoft Visual Studio .NET, are there symbols defined by default with which I can determine which .NET framework is being used for the compilation?
I'm writing a custom control that inherits System.Windows.Forms.PictureBox. I'd like to override the OnMouseHover event handler but obviously this would not compile when I use the control in a .NET Compact Framework sollution.
So I was hoping to embrace the override with the #if compiler directive - something like this:
#if FULLFRAMEWORK<br />
protected override void OnMouseHover(EventArgs e)<br />
{<br />
base.OnMouseHover(e);<br />
}<br />
#endif
However, there is obviously no such symbol as FULLFRAMEWORK and I would prefer not to have to define it in every one of my projects that use this control. Is there a symbol that is defined by default that I could use for this purpose?

Hi,
AFAIK there are no predefined symbols.
I usually define either NET11 or NET20 in my Visual projects to discern different
.NET versions...

Hi all,
iam new to .net,iam getting problem at parsing the file.My sample file contains key value pair data,and key value is seperated by space and field is seperated by line.This is the sample code:

In above file GENEVAVERSION 5.0 is one key value field it is seperated by space and each fields are seperated by pipe symbol and each is in new line.
my problem is how to parse this file as xml.pls send me some sample code it is more helpful for me.
