Hi,
I am developing an application in which i use to select data from one grid remove that & display it to the second grid.
I store those data in a local mdb file . when i am selecting rows in bulk(around 50-70 at a time)and then wanted to cut and display in the second grid i am getting this error .
Please help.

The error means what it says. Your code is locking the MDB. Not sure what sort of help you're hoping for, when you don't post any code.

hi there,
I have a simple WPF window with a button in it.
now during runtime, i pass this button control to another function, and there, i want to know the parent of this control. ie the window, with the full namespace.
any way for this thru C#

We have a WPF forum. The control has a parent property, to know the type, you can use the GetType method, you can also use reflection. Any method that gets passed a control, sounds a little ugly to me.

Hi
Because of various graphics that i use in my app, I want my app to run under Windows Classic Theme regardless of the theme the user has selected before they run my app.
Where can I find info about the API calls I need to swtich tmeme at start up and to restore to users' chosen theme on exit?
Thanks.

Swapping the whole system theme is a little user hostile. It would be better to skin your app to make it look the way you want.

That's basically what I want to do, but using Windows Classic Theme for the skin instead of a custom skin, but didn't think of it that way.
Now all I have to do is find out how to do it - there are a lot of articles about skinning, so it is difficult to find the best article to look at.

Hi All 
I'm working on a little web browser that supports tabs and all is good but everytime I click a link that is supposed to open in a new tab or window, instead of opening a new window/tab in my own web browser that i am making, it chooses to open a new instance of the system's default web browser (Internet Explorer) and I have tried to find some articles/samples on the web but have been unsuccessful.
Does anybody know how I would go about allowing links to be opened in a new tab in the browser i am making?
Any suggestions would be greatly appreciated
thanks
jason

Well, unless I misse the memo ( possible ), the web browser control doesn't support tabs. So, you'd have to catch the event of a page opening, swallow it, and create your own tab, and open the URL there.

Reading the MSDN, it looks like the NewWindow[^] event is what you want.

Thank you Christian for yout time and help, that link was very useful. I'm actually wondering how I could've overlooked that page in the first place.
Well, I am now browsing the web with full tab support yay! Thanks again christian. Maybe I could turn this into an article??

Well, if you finish the project, then I'd imagine you could write an article which covers this and other things you learned along the way. People are always writing their own browsers, so I'm sure it would be well recieved.

I'm planning on adding a new type of favorites system, but also supporting existing favorites that have been created by other browsers, once that's finished I'll start writing the article. I'd love to see what others have to say about it.

hi,
zhe subject is that
class Class1 {
private string str = "class1.str";
private int i = 0;
static void StringConvert(string str) {
str = "string being converted.";
}
static void StringConvert(Class1 c) {
c.str = "string being converted.";
}
static void Add(int i) {
i++;
}
static void AddWithRef(ref int i) {
i++;
}
static void Main() {
int i1 = 10;
int i2 = 20;
string str = "str";
Class1 c = new Class1();
Add(i1);
AddWithRef(ref i2);
Add(c.i);
StringConvert(str);
StringConvert(c);
Console.WriteLine(i1);
Console.WriteLine(i2);
Console.WriteLine(c.i);
Console.WriteLine(str);
Console.WriteLine(c.str);
Console.Read();
}
tell me why "Console.WriteLine(str);" and "Console.WriteLine(c.str);"
zhe two sentence have two different results!
I know that zhe "string" is reference type!
but here i am puzzled!

While you are correct that string is a reference type, you cannot change which string the local variable str in Main is referencing from the StringConvert function since you pass it by value. All you can do is make the parameter to StringConvert refer to another string, which will have no effect outside the function.
In the case where you passed a Class1, you are modifying the reference contained in the object referred to by the parameter, which is the same object referred to in Main. If you had put the line c = new Class1(); as the first line in StringConvert, it would no longer change the value in Main because the parameter in StringConvert would now be referring to a different object.

i want to send mail to yahoo mail automatically using c# code.

I want a Porche.....
Seriously, what have you tried ? Why do you have a specific issue with yahoo mail ? A quick google leads me to believe that a lot of people are asking this, so perhaps the issue is that yahoo does not support sending mail through a third party, or through the protocols that .NET supports.

Yahoo doesnt provide free smtp/pop3 service so you cannot use your Yahoo id to send mails from any other email client.
To use Yahoo mail you wil have to buy the Pop3 Service from yahoo.

I have an application I made that simply gets the current directory using System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location goes up a directory level and then runs a file in that directory using System.Diagnostics.ProcessStartInfo and System.Diagnostics.Process.Start. The file works fine if I run it on my computer but if I put the file on a Shared Network Path I get the below error:

Obviously, if it can be fixed at all, then it requires you to set the right permissions on your intranet.

We were actually looking for a way to fix this through code. We don't want to tell everyone that uses our software that they have to change there intranet settings just to run one file.
