Right, that would be good. Or the numeric types should implement some sort of IDoMath interface and we could use that.
I also want an enum constriant.
|
|
|
|

If they made it so we had a Numeric constraint, or they implemented some common interface (INumeric), that would fix it for all the integral data types and enums too in one go.

I want enums separate from the other types. I have generic classes that should accept enums only. As it stands, I have to check at runtime and throw and Exception.

Thanks for your help,

Its hard to comment about it but a wild guess could be to check your dock and anchor properties.
|
|
|
|
|
The dock is fill.
and anchor is top and left.
I saw that if I set the parameter in an event such SelectedIndexChange it works.
but I feel that is wrong to do such a thing (and also it doesn't cover all the cases)
any other guess?
Thanks.

this comment made me think that may be its some code level change overriding the design view changes. Go through your code and make sure that your adjusted styles not being overridden at code level.

i got the code...
thank you...
if (gvcomments.Rows[pre_Index].Cells[CommonConstants.Created].Style.ForeColor == Color.Red)
{
gvcomments.Rows[pre_Index].DefaultCellStyle.Font = new Font(gvcomments.SelectedRows[0].InheritedStyle.Font, FontStyle.Bold);
}
else
{
gvcomments.Rows[pre_Index].DefaultCellStyle.Font = new Font(gvcomments.SelectedRows[0].InheritedStyle.Font, FontStyle.Regular);
}

handle related index change event and always keep track of previous index in some location. In this way you will always have a valid old index saved and before updating it to newer index you can make use of it.

Based on the Wikipedia definition of TCP Window Scale Option[^], it seems you don't achieve it at the application level.

Try setting up the binding BEFORE you read the data.

Hi,
I have a panel on a windows form.
In the panel, I have a label, I have set the visible property of the label as False in design time.
now at runtime, in a function I am trying to make label visible like this,
label1.visible = true;
but the label1.visible property does not change, it still has false value, but once the form executes completely, label becomes visible, I cannot understand, How this is happening.
can someone tell me that why the label1.visible property does not become true, when I explicitly assign true to it.
Thanks in advance,
Regards
Mahesh

It sounds like you are running a process that is holding up the UI, basically the form is not being refreshed until the process is complete. Adding the following line after settings the visible property of the label to true should work..
label1.Visible = true;
form1.Refresh();
Life goes very fast. Tomorrow, today is already yesterday.
