I solved it.
I set Major and Minor to be type of int instead of string and now it works with VersionInfo v = new VersionInfo(); x.Major = 1; x.Minor = 0; set in GetVersion() function where I read from Xml.
Now I have to use ToString() when using GetVersion().Major or .Minor, but that's not the problem.
Thank you both for your time.

First, I have ComVisible set to true for the entire assembly.
I have (abstract) base class A. There are interfaces IA and IAEvents for accessing properties of this object and exposing events.
[ClassInterface(ClassInterfaceType.None), ComSourceInterfaces(typeof(IAEvents))]
public abstract class A : IA
{
...
}
I then have a derived class B and an interface IB (IB also derives from IA).
public class B : A, IB
{
...
}
Given an instantiation of B, I can access (from COM) properties/methods defined in either IA or IB.
However, when I then add a IBEvents (deriving from IAEvents) and change class B to:
[ClassInterface(ClassInterfaceType.None), ComSourceInterfaces(typeof(IBEvents))]
public class B : A, IB
{
...
}
I can no longer access methods/properties defined from A/IA. Only those defined at the B level. Commenting out the attributes on B will make it work, but of course the new events from IBEvents do not exist. Is there some wierd trick with regards to inheritance and COM that is preventing this? Is it still possible to do what I want? I intend to have a great many classes deriving from A each with their own unique set of properties and events in addition to the 'base' ones defined in A.
Ideas?

Hi,
I made a few textboxes where a user would put data in.
If the first box has data entered, it should enable the next textbox.
The problem is, what can i do if the user presses a few times the spacebar.
Because the next textbox will be enabled.
Thanks in advance!

You can trim the Text property just like you would trim a string (thats just what the Text property is).
I am not sure if that was your problem, though. It reads like you are referring to setting input focus to the next textbox? Please clarify.
Cheers,
Sebastian

Hi Sebastian,
Maybe you understand the code better than my words 
private void Textbox1_TextChanged(object sender, EventArgs e)
{
this.Textbox1.Text.Trim();
if (this.TBLicensePlateCar.Text == string.Empty)
{
MessageBox.Show("Nothing is typed", "Information", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
else
{
this.data = this.Textbox1.Text;
this.NextTextBox.Enabled = true;
}
}
One char is enough to enable the next textbox. But is shouldn't be a space.

This line returns a new string, so you must assign it to something otherwise the trimmed copy of the string is lost. Probably what you wanted was
this.Textbox1.Text = this.Textbox1.Text.Trim();

Hi J4amieC,
That worked! Thanks.
I do get the messageBox twice now. Wonder how this keeps happening...
|
|
|
|

My guess: The text-changed event fired again.
Scenario:
User enters a "space" in the first textbox. The text-changed event fires.
The method gets called. The string is trimmed (now empty) and stored in the Text-Property. The new text (empty) is different from the old text (space) so the text-changed event fires AGAIN.
Completion of the first call occurs (MessageBox and all).
The method gets called again for the second text-changed event. This time, trimming yields the same string as before, so no change occurs.
Completion of the second call occurs (MessageBox and all).
You could either remove the handling from the text-changed-event during the trim (not sure if that works) or you could actually compare the new string to the old one and return immediately if they match.
And I am sure there is a better way 
Cheers,
Sebastian

Hi Sebastian,

Hi,
I'm testing a piece of hardware that receives network traffic and want to see exactly at what frequency it gets overburdened by the load of traffic. To do this I wrote a simple program that sends packets at a set interval.
My problem is the following: The hardware doesn't break up at intervals of 1 millisecconds, so I need higher resolution delays or timers in my program (somewhere in the order of 50 microsecconds or so) than the timers I've been using (Threading.Timer or Forms.Timer). I found an article on the net saying this is possible with C++, but I can't find any info on the subject in c#. Can anyone help?
Thanks in advance for any help I might get...

Hi Gurus,
I'm using the PropertyGrid control, and I want it to show a button.
But when I set the PropertyGrid.SelectedObject with a object that has a Button property, the PropertyGrid shows the buttons properties, and I want the button to be shown as drawn and clickable button without any access to its properties.
How can I do that?

Thanks
Sharon

There are three file Default.aspx, Default1.aspx and Default2.aspx.. Is it possible to call remaining two pages if I click on a Button in the Default3.aspx .? The pages are individual.. If i click on a button in Default3.aspx the page_Load Event of the remaining two pages has to be called/processed... I am using ASP.NET 2.0 and C#. pls give me suggestion. If you send code its great.
Thanks
Hosanna.

Sounds like your overall design is horribly wrong.
If you have code that every page should process, put it in a base class. If it's related to business logic, put it in your middle tier ( and perhaps call it from there in a base class ).

Simply restateing your question does not help anyone answer you more fully than Christian already has!

Seriously, I answered you, your page design is completely broken. You cannot do this, you need instead to write your pages properly.
