Hi,
is this .NET 1.x or is it >=2.0 ?
did you disable the cross-thread checking ? you should not.
seems like you try to create and show a form with a thread, and later hide it
from the main thread. This is illegal and will result in all kinds of anomalies.
IMO the right approach is to crate, show and later hide the WaitingForm in the
main thread, and do the "loading data..." stuff in some other thread (or maybe
a BackgroundWorker).
If the loading thread needs to update the WaitingForm, it must do so using the
Control.InvokeRequired property and Control.Invoke() method.
If unfamiliar, look it up on MSDN and/or read some CodeProject articles about it.

The .NET framework doesn't have any intrinsic ability to translate text from one language to another.
You would have to write your own language translator.
Alternatively, there are websites that provide language translation services. You could consider sending a translation request programmatically to one of these sites and screen-scraping the HTML to get the result.

Hello Gents.
Am trying to alter the way ALT+F4 closes an application and hope I can get some guru help here.
I have a component that calls an Windows form for a regstration page. On that Windows form I have two buttons.
One closes the application by:
System.Environment.Exit();
and the other button closes the application by:
System.Enviroment.Exit(-1);
The first only closes the form that runs inside the component, the later closes the whole application including what ever application who calls the component.
Now my problem is that when the form that opens inside the compoent is active and a user hits ALT+F4, then the only the component closes and not the whole application.
To me it seems that a standard ALT+F4 is like invoking System.Environment.Exit() and not System.Enviroment.Exit(-1).
Is there any way I can force ALT+F4 to close the whole application like System.Enviroment.Exit(-1) does?
Cheers,
Ronni

Found the answer...
private void form1_FormClosing (object sender, FormClosingEventArgs e) {
if (e.CloseReason != CloseReason.ApplicationExitCall) {
System.Environment.Exit (-1);
}
}

I was finally able to do that 1st step of getting data from Excel to the dataset. Now I am taking that dataset and converting into XML.
private string GetXML()
{
string XML = dsSource.ToString();
return XML;
}
And I get an error saying "The name 'dsSource' does not exist in the current context"
What should be the correct code? Please HELP!!!
|
|
|
|
|
It means that dsSource is neither declared in GetXML nor it is a 'global' variable. Perhaps you have declared it as a local variable in one of your methods.
|
|
|
|
|
I tried:
#region private dsSource GetXml()
string Xml = dsSource.GetXml().ToString;
#endregion
But it still gives me an error. that the name dsSource does not exist in the current context.

When I am using a varible inside a method (let's say 25 lines of code)
Should I create an int variable or Int32? What the heck is the difference?
I didn't get any requirements for the signature
|
|
|
|
|
There is no difference. int is a C# keyword that's simply an alias for System.Int32.
|
|
|
|
|
Oh, that clears it up then. I suppose string and String are the same as well?

The Framework classes have names starting with an uppercase letter,
such as System.String
C# has type specifying keywords in lowercase, each of them corresponds
to one of the System.Xxxx types. Yes string corresponds to System.String

Here's a hint: if you're in Visual Studio, hover your mouse over string, or double, or int, and it should pop-up a little info showing the aliased type.
