hi buddies,
I am facing a big problem while usig Asynchronous socket communication for a simple server on chat application.
The problem is that, while sending message from server to client and from client to server the messages are breaking, ie intead of "Heloo how are u..". the client will reach the message as "Heloo ho" and "w are u..". Please help me with good solution to avoid this.
the code is just like http://www.codeproject.com/csharp/socketsincs.asp
please help me.......;P

Is there a way that I can have VIM like movement for my coding in C#? I am using
Microsoft Visual C# .NET version 7.1 (I think?) on Windows 2003. Any help would be much appreciated!

I will try to keep this question short and simple in compliance with codeproject standards. When working with MdiParent, I need to add some controls to the MdiParent. Then when displaying the MdiChild form, those controls on the MdiParent display in front of the MdiChild rather than properly being covered by the MdiChild.
To duplicate the conditions of the question. Create a windows C# form, set the isMdiContainer property to true, create a menu for the C# windows form, and then add the following code to the menu click event. Add a lot of controls to the MdiParent form including a picture box, a combo box, a text box and a panel control. After that create another windows C# form as the MdiChild form.
Add this code to the menu click event:
<br />
protected void MDIChildNew_Click(object sender, System.EventArgs e)<br />
{<br />
Form2 newMDIChild = new Form2();<br />
newMDIChild.MdiParent = this;<br />
newMDIChild.Show();<br />
}<br />
Helpful link: http://msdn.microsoft.com
After duplicating this, run the application and click the menu event. Note that the MdiChild form is behind the MdiParent form controls including the picture box, the combo box, the text box and the panel control that were added. How do I correct this problem?

Can someone point me in a direction on how to solve this problem?
I have to be able to find out if a file I am pointing to is local or not.
I can point to a file through the network neighborhood or through a networked drive. I think finding out if the file was accessed through the network neighborhood would not be a problem, its when I map a network drive. Once the drive is mapped, it is given a drive letter like any other local drive.
Help would be much appreciated.
PS.
This seems promising...
http://www.codeproject.com/csharp/mapnetdrive.asp[^]
My idea was to try to unmap the drive and if my attempt fails, the drive must be local. The problem is, that if I unmap a drive with a username:pw, I have to remap it with the same username:pw which I may not have.
For the network neighborhood,
Does checking the root of a file work?
ex.
\\NAME\c$

One possible solution is to use the WIN32 API function GetDriveType.
By passing in the drive as a string, the function will return the drive type as shown below.
int nDriveType = GetDriveType("Z:\\");
if (nDriveType == DRIVE_REMOTE)
MessageBox(NULL, "Network Drive", "Network Drive", MB_OK | MB_ICONINFORMATION);
Hope this helps.

Hello everyone,
I have installed Crystal Reports 9 additional to .Net 2003. Referencing to the newer items in the referenclist .net changes automaticly to the older .net parts of crystal reports engine, etc.
I tried to change the references externaly in the .csproj file but after loading the project the old configurations settings are set.
But using a sample project, all new references to crystal report components are correct.
Where are additional information placed to tell .net which references to use for ?
Thank You in advance
Frank

has anyone seen any goood firewals in C#. frankly i havent seen a single firewall in .net. Is it possible t make one (does .net have the power?
|
|
|
|
|
Yes, c# and all the .NET languages have the power. The question isn't whether .NET is capable, but whether it's appropriate. A poorly implemented firewall can be a bottle neck and a major security risk. First off, a firewall 'should' be hardware based whenever possible. Search on Google for a Java-based firewall; you won't find much. If you're really interested in how the sockets and communication works take a look at the Cassini web server source code. It'll get you on the right track in terms of working with ports.

Hello,
I am at the moment not so experienced with C# but I am learning.
I have the following problem.
On Form1 i have 1 textbox and 1 button. When I press the button it opens a send form (Form2).
There is also one button on Form2, when I press it, the value of the textbox on Form1 needs to change.
Is this possible?
I try to make textbox public but than i need a reference to the Form1 object.
This is ofcourse simplified representation of the problem i have.
If I do this on Form2:
Form1 form1 = new Form1();
form1.textbox.text = "test";
Nothing happens, and i suppose this is normal, because you create a new instance.
What i want to do is on Form2:
Form1.textbox.text = "test";
At compile I receive the following msg: An object reference is required for the nonstatic field, method or property.
I don't think that i have to make the textbox public static. I am a bit lost in this situation, is someone there who can halp me and clear things out.
Thanks

What you can do is pass the reference of Form1 to the Form2 constructor.
Then keep the instance in a global variable and you can set the text whenever you want.
The Textbox object would also need to be made public, or (better way) have a property on the Form1 class that will set the text when called.
Cheers,
Simon

Thanks for the fast reply.
Still for me it is difficult and i feel that i am lost.
Ofcourse i can make a public variable and when I close Form2, Form1 becomes active i can set the Textbox with the variable. But i don't like this work arround method.
Can someone show me a simple code example maybe?
Thanks.

Hellow,
I found the solution to my problem.
I resume here for in case other people were strugling with the same problem.
Form1:
make textbox1 to public
private void button1Click(object sender, System.EventArgs e)
{
Form2 _form2 = new Form2(this);
_form2.Show();
}
Form2:
private Form1 _form;
public Form2(Form1 form)
{
InitializeComponent();
_form = form;
}
So on Form2 you are able to do this: _form.textbox1.Text = "TEST";
You will see that the value in Form1 textbox1 will change to TEST
Greetings.
