Well for this, you can use the datagrid row properties to find out which are the changed/modified rows and likewise only update those rows in the DB.
Does that answer what you looking for?

I use an IPCChannel to relay information between 2 apps on the same PC. This all goes well. The problem is when I close the server side application, and then start it again I can not re-establish the IPCChannel untill I close the client app that connected to the previous server side app too.So I guess somewhere the .NET framework still keeps track of that IPCChannel. I tried to run Channelservices.UnRegisterChannel on the server side app before I close it and running an UnRegisterChannel on the client side too, but to no avail.
Does anybody know how I might fix this problem?
Thanks for any help,
Davy

Reinitiate the remoting setup request by dynamically performing the steps to register the channel and connect. You need to ping the Server and when it becomes online, reinitiate the remoting framework from the client.

Acctually I also dont know the answer perfactly coz I didnt realize the problem ,but I can suggest you one solution ,try that one and inform me if that works or not ,ok?
You should convert your string in to UTF8 encoding first and than send it,or you can use StringBuilder with UTF8 ,Which is there in System.Text namespace, try that out and let me know ok?

lo,
the text i want to encode comes form textbox.text, so this is a string
if i use encoding.utf8.getbyte(textbox.text) i get an error because it
is'nt a char[] char.
do you know how to solve this or am i going the wrong way here?

|
|
|
|
lo,
found the solution:
public Form1()
{
InitializeComponent();
port.Encoding = System.Text.Encoding.UTF8;
}
in case you'll ever need it :p
thx alot

i have application program taht will use
username and password
i ask about what is the best coding algorithm
to pasword and where i can find it

Hi,
You can try using MD5. There is an encoder built in VS2005. However you must know that MD5 cannot be decoded so if you want to test the input password with a stored one you should convert the input password to MD5 and then compare it with the stored password. Search MSDN for MD5.
Hope it helps.

Hello
I have a C# application that uses several Libraries (Crystal ...). The application always runs well.
Since a few days I focus the problem, that I can start my application only with the debugger (the Debug and the Release version).
If I start the *.exe directly, the application crashes ... Most times an 'Out Of Memory' exception occurs.
I added some debugging output and I see, that I enter the Main() but then it crashes ...
The application also crashes, if I take an old (former running) *.exe file.
Do you have any hint how I could handle it?
Thanks and best regards,
Martin

Hello!
I have an application that uses a tabcontrol with a couple of tabpages. However, I wonder if anyone knows if there is a way to make one of the tabs appear without clicking it?
Best regards,

Set either TabControl.SelectedIndex or TabControl.SelectedTab property.

Thank you for that answer. SelectedTab really solved my problem.

Yes. Use a timer to toggle between tabs, and on elapsed duration, send a click event to the tabcontrol with the required paramaters, simulating as if the user clicked. This will make teh tab control change the active tab, based on which tab index was passed in the event handler call

I have MyControl (Grid), and i override IsInputKey method in it.
protected override bool IsInputKey(Keys keyData)<br />
{<br />
bool bIsInputKey = true;<br />
<br />
switch (keyData)<br />
{<br />
case Keys.Left:<br />
break;<br />
case Keys.Right:<br />
break;<br />
case Keys.Down:<br />
break;<br />
case Keys.Up:<br />
break;<br />
default:<br />
bIsInputKey = base.IsInputKey(keyData);<br />
break;<br />
}<br />
<br />
return bIsInputKey;<br />
}
It work ok, but if i place MyControl on other control(TabControl for example), that don't respond to keys.
What i must do?
Thank's to all answers asap!
