I was thinking break will take me out of if() which was in the foreach().
But it was taking me out of the foreach().
So some parts of code was not executed. Instead of break I used continue.
So my problem was solved by this way:
foreach(char ch in <code>stb.ToString())
{
......................
if(ch.ToString()=="\n")
......................
}
The "\r" doesn't appear anywhere.
Performance is low for other reasons. I should think other solutions.
Thanks.

Just look up the DateTime and TimeSpan classes in the framework.
They hold everything you need.

DateTime d1 = ...;
DateTime d2 = ...;
TimeSpan diff = d2 - d1;
now diff will give you hours, months, days... whatever you need.

Hi all:
I am recently thinking is it possible to serialize an assembly (I descover it in run-time) and transfer it to the remote client. Thus, the client can execute it? Bellow are more on my idea
Server:
Discover some assembly that the client may need the function that I already pre-compiled as a .dll file in server, then the server load it and send the assembly to the remote client.
Client:
This is a generic client it doesn't have much functionality by itself, but it can discover what assembly have on the server. If the function the client is needed, server will load the assembly dynamically and transfer to the client. So the client have the function to use.
By implementing this, the client can be compact and dynamic in the function.
The client even can write the source code and compile the source into an assembly which will be stored in the server. And let other client to discover and use this assembly too.
Regards,
Joel

Im not sure if I understand what you mean. Why dont you just send the assembly as binary data, save it on the client machine and load and execute it via reflection?

Your best bet might be to go with .NET Remoting. Read the following article : Microsoft .NET Remoting: A Technical Overview[^]

I created a thread a little bit ago that has some code that demonstrates a problem that I have. Basicaly I'm trying to do double buffering and I "trick" windows.forms into painting the control onto a buffer, the problem is, is it also paints a black rectangle where the control is(I know it is also painting my control because I can scale the window and the control will go while the black box doesn't)... I also know it is the parent that is doing this and not the control since I have completely disabled the control's painting functions and still have the problem... It seems that either the form is excluding the region from being updated for painting by the form's OnPaint/OnPaintBackground("no need to paint behind a control") and painting it black, or that its trying to paint the control but there is some kinda "bug"...
I've overriden the forms wndproc and took out the WM_PAINT and it doesn't draw the black box, but does not render that area at all(which makes me believe that the form has excluded the controls region from being painted at all, I put painting the background on a timer, so the background is showing up... just not anything where that square is...)...
since I don't know much about how windows handles the control, I'm wondering if someone can help me out... I'm sure theres somethere where I can tell windows not to exclude region behind the controls from being updated... not sure if its in my PaintEventArgs or somewhere in the WinProc...
Anyways, thanks for any advice/help...
BTW, I do not have WS_CLIPCHILDREN set in my styles(override CreateParams)... which would seem to be the cause if I did.

My problem is ,
I want to make a secret form that I want to make it possible to see when key combination I defined pressed...
For Example :
when ( Shift + ALT + S ) pressed my secret form will be visible..
but I can only catch one key...
I tried something like ,
if(Control.ModifierKeys == Keys.LShiftKey && Control.ModifierKeys == Keys.LControlKey) Doesnt work && is invalid syntax for keys
then tried
if(Control.ModifierKeys == (Keys.LShiftKey + Keys.LControlKey))
no doesnt work...
if you could help me I would be glad..Thank you

Do the following:
Set the property "KeyPreview" of the form you want the key combination to be available in to "True", otherwise you won't get the keys if another control on your form receives and handles them before you do.
Then add an event handler for KeyUp to your visible form and add this code:
if (e.KeyCode == Keys.S &&
(e.Modifiers & Keys.Shift) == Keys.Shift &&
(e.Modifiers & Keys.Alt) == Keys.Alt)
{
MessageBox.Show("Secret combination pressed: Shift+Alt+S");
e.Handled = true;
}
else
{
e.Handled = false;
}
That's it.

I'm trying to build a Assembly that extract a compressed file when I start the Assembly. I have found samples that extracts the resources but no code to add resources programmaticly. Every sample I have read says something like this:
"The next step is to add the files you want as a resource to the project. To do this you right click on the project name, and select "Add Existing Items." This will bring up a dialog where you can select the files to add. This will cause VS.NET to copy the file into your project's directory if it is not already there. This file is now part of the project you previously..."
I have tried to use the System.Reflection.Emit.AssemblyBuilder class but when I try to build the project it's only saying that I can't use it due to it's protection level.
Please help me someone!
Sincerly, Richard

How many ways are there to pass values in windows forms.
My brain is 2 small for all the knowledge that I need.

Lots! Are you asking about a particular method? What exactly are you having problems with?

I want to open a new form and then retrieve a few values from the new form.
|
|
|
|

Dirty Method: Make all controls of the form public. Then you have complete access to everything.
Clean:
- Make public/internal properties/methods to read the values from the form.
- Let the form fire events when values are changed. These could be handled and evaluated.
If the new form ist shown modal you can also:
- Define a function in the new form which will show it modal and return the value you need. If you need more than one value you could insert some out/ref-parameters.
There will be thousands of possibilities to exchange values, but I think you should try it with properties (as mentioned above)

What a curious thing to say.
It is commonly known that humans generally do not exceed 10% usage of their brain's capacity. Therefore it is more likely that you are not utilising the capacity you have efficiently.
If you search Amazon for the author "Tony Buzan" you should find some books on how to more effectively utilise your brain so that you retain and recall information more efficiently.
Does this help?

I like my forms to fire events when values change or certain actions such as save are made.
Alternativly. get and setting of public Properties is also good.
A lot depends on your model of development and what the values are being passed for.

hello...
Is it possible to disable the windows shortcuts like 'Ctrl+Alt+Del' and 'Alt+Tab' ?
If anyone know how please tell me!

It's not possible to disable Ctrl-Alt-Del. But you can disable everything else... All you need to do is write an app that hooks the keyboard and doesn't allow such key combinations through.
You can either P/Invoke the Win32 API Hook functions or use the Application.MessageFilter.
Hooks of this type are covered in this[^] article by Michael Kennedy.
I did something similar and found it much easier to write in C++ and the resulting executable has the smallest of footprints compared to a managed code version in C#.
