Hi,
I have a form with two buttons. In my form code am I able to override the form methods. But I cannot figure out how to override the Refresh method of the two buttons.
Here is what I am trying to accomplish
public override void Refresh()
{
this.Enabled = (cboCustomer.ToString() != "");
// "this" being the button itself
}
Thanks in advanced.

Valeria,
Thanks for your reply. I am sorry to be so dense on this, but still don't know how to implement.
One of the buttons I have was added to the form using the toolbox window.
public class SQLConnect : System.Windows.Forms.Form
{
...
private System.Windows.Forms.Button cmdConnect;
...
}
I have tried the to override the Refresh on the button with the following:
public void override cmdConnect.Refresh()
{
}
But c# does not like it.
Thanks for your help.

Valeria,
The reason is because I would like to set the "Enabled" property for that button based on a condition.
for example...
if (cboCustomer.ToString() == "")
this.Enabled = false;
else
this.Enabled = true;
Is there a better way (or best practice) to do this?
Thanks

Hi!
I have such problem:
I wrote DLL which contains many controls, it always attached to solution like a single project. All works fine till I try to change version of my DLL in AssemblyInfo.cs file...
After change all form which use custom control in designer look strange. All custom controls disappeared and on Task window has many errors like this one:
Could not find type 'MenuItemEx'. Please make sure that the assembly that contains this type is referenced. If this type is a part of your development project, make sure that the project has been successfully built.
All references in project are set well... Application start without any problems... but I loose opportunity to edit any form!!!! I can design it and after close and try to open again loose all control on form...
Does anyone can suggest how to fix this problem?
The main problem is that I can not change version number back... release of application was accomplished!!!
Good Luck

This does not help. I'll try such solution at the beging...
Even More:
- i clean all forlder bin and obj
- i clean GAC
- I clean NGEN images
- at the end i search all instances of DLLs on my comuter and delete them... (in hidden folder too)
- I rebuild control library
- register it Designers part in GAC (needed for IDE)
and nothing good happens... I still got the same problem... I spend more then three days trying to solve problem in differ menner. 
Good Luck

If your control library is strongly named (sounds like it is) then by default if the runtime can't find that specific version number it will fail to load. To get around this you can include a publisher policy which tells the runtime that when version a.b.c.y (or a range of versions) is asked for to use version w.x.y.z. You can also use a configuration file which does the same thing, but requires that whoever controls the .exe put some entries in the .exe.config file.

I have a lot of description to write for each property in a property grid. My problem is that I don't see any methods to make the description pane (or help pane) higher.
Is it possible to set a new height for the description pane in a property grid ?
Thanks for your help !

Nope. That's a function of the IDE, not your code.

I don't think he means the one in the IDE. I think he means his own property grid.

How do i make the scrollbar stay at the bottom of the page. Iam developing an application in .net in where im displaying a datalist in a window and I am adding items to the datalist at runtime. Its size goes on increasing and i want the scroll for for this to remain at the bottom so that im able to see the last item entered.

Without knowing exactly how you're displaying things, the general technique for this is to write code that selects the last item in the control (thus moving the view to make it visible). If that is out of the question, you could record the current selection first, then move back to that one after making the last item visible.
Certain types of controls behave better in this respect. Check to see which controls could possibly display the data you want, maybe one of them has a method that handles this easily.

Hi
You can create a Panel and set its Dock property to DockStyle.Fill (to fill the form) and move your objects (e.g Datalist) to the panel (except the statusbar)
Unfortunately, you can't handle the Scroll event because Panel doesn't have this event.

Can someone advise me on how to convert hex conversion in C#? I am currently trying to get the string in a textbox, say "20" and convert it to its hex form 14, and then display it onto another textbox.

From help (I did something similar to this) :
Console.Write("{0:X}", 250);
I'm not sure if you can do that directly to a string or if you need to use a StringBuffer class like I did.
This is some code how I retreived color codes in individual colors (in bytes) and converted them to hex strings.
<br />
StringBuilder oBuffer = new StringBuilder();<br />
string strColorCode = "";<br />
byte byRed = 0;<br />
byte byGreen = 0;<br />
byte byBlue = 0;<br />
<br />
<br />
byRed = oColor.R;<br />
byGreen = oColor.G;<br />
byBlue = oColor.B;<br />
<br />
strColorCode = "{0:x2}{1:x2}{2:x2}";<br />
oBuffer.AppendFormat(strColorCode, byRed, byGreen, byBlue);<br />
<br />
return oBuffer.ToString();<br />
There are only 10 types of people in this world....those that understand binary, and those that do not.

I just found out how to do the conversion, thanks to your format string :
strColorCode = "{0:x2}{1:x2}{2:x2}";
This is what i did :
short sh = System.Convert.ToInt16(tbTextBox.Text, 10);<br />
tbTextBox2.Text = String.Format("{0:x2}", sh);
