no, i dont want bankers rounding,
yeah i know your way is good, but a little bit long as i have to write it about in 100 lines in a big loop
so you can think 100 * 3 repeating lines will hard to understand and a little mistake can destroy the project

Hi,
you can put all three lines in a single one (not recommended).
you can turn it into a little method.
anyway, if you think you need it a hundred times, chances are there is something
wrong with your data representation to begin with. Normally there is no need to do so,
using arrays or collections should avoid a lot of code duplication (which normally is
a bad idea).

oh yeah, a method is good idea, thanks

public static double GetValue(string what)
{
return multiplierDivider * (int)(multiplier * Convert.ToSingle(what) + 0.5);
}
what do you think about it

No, it only rounds to an even number if the number is right in the middle of two possible results. I.e. both 1.00015 and 1.00025 would both be rounded to 1.0002, but 1.00014 would still be rounded to 1.0001.

Hi Guffa, you're right.
I forgot the details, since I decided long ago it was of no value to me.
I'm an engineer, so for me if 1.00015 rounds up, so should 1.00025
And I never understood the advantage, if any, of the banker's rounding.

The advantage is that in the long run it will round up just as many times as down. If you are doing millions of transactions, and the roundings doesn't even out in the end, you may loose a lot of money.
For us non-bankers, consistency makes more sense.

I am creating DataGridView dynamically could anybody tell me how to set
tab order for the same.
Truth Is The Simplest !!!!
|
|
|
|
|
tab order of DataGirdView!!!
AFAIK i know you are talking about column order of DGV, if yes then you can not change column order in one line, you need to delete all columns then add in the required order

i try the code,
<;asp:buttonfield buttontype="image" imageurl="~/Image/Blue hills.jpg" commandname="Select" />
but it accept single image .i want image folder or '<%# Eval("exe")%>'
|
|
|
|
|
you can't set imageUrl to a folder...
i think you should look at Repeater or adrotator control for that
|
|
|
|
|
i set image in my folder,
<asp:ImageButton ID="Image1" runat="server" ImageUrl='<%# Eval("filename")%>;'OnCommand="ImageButtonCommandHandler" Width="150px"/>
i show all image in grid view but how to show particular related .exe file in image click event.

Morning,
I've spent ages trying to sort this problem and I've got nowhere. I was just wondering if anyone here had some across it before.
The best way to describe it is with picutres
with problem[^]
As you can see on the above picutre the display is "mangled", showing through to the window below and generally looking corupt.
If I force a refresh (this.Refresh()) then it renders correctly as shown on:
without problem[^]
As the problem seems to occure everytime the data on the form is changed in anyway (add to table, resize form etc) I don't really want to manually force refreshes all the time in order to sort it.
At first I thought this problem was due to graphics card/driver issue on my development machine but after testing this on 4 other machines (all different specs) I'm not so sure as the problem was present on those machines as well.
Any ideas would be very welcome.
Thanks
Sam

Just a bit more info.
The DataGridView on the form is one that I have subclassed from System.Windows.Forms.DataGridView
It has the following handler declared in its ctor.
this.CellFormatting +=new DataGridViewCellFormattingEventHandler(DGVEnhanced_CellFormatting);
If I comment this out then the problem goes away. If I leave it in (even if the DGVEnhanced_CellFormatting function is empty and does nothing, then the fault resurfaces. Very strange...

I have wizard kind of Windows Application with Forms having Prev and Next buttons. Currently i have set the Location for all the Forms on Form_Load() method using this.Location = new Point(100, 100);
Now my requirement is that when using "Extend my Windows desktop onto this monitor” setting in Display/Settings Properties, the form should stay in the user’s selected monitor. When i go to the Next form it defaults to the main monitor.
I tried removed the size setting on Form_Load but when i navigate to the next/prev forms the location of the form is not properly set. It randomly positions itself.
How can i do this?

I'm not sure if I'm understanding you fully, do you mean you're using dual screens and you want the form to load on the screen it did last time?
There are a number of types of default form position.
Look at the form's StartPosition property.

Yes that right. I'm using dual screens and i want the next form to load on the screen as how the previous form occupied 2 screens. How can i do that?

Hi,
Below you see the string array which I am populating BUT I would like to populate dynamically becuase the dataset where the data is coming from may have different number of records each time.
Could you please correct the preferred method mentioned below as it seems I can not use .Add to add into the string array.
p.s. I do not want to use an arraylist
Thanks
Present method:
private string[] _securities = null;
_securities = new string[]
{
"XS0166639566 corp cusip","XS0184546371 corp cusip", "XS0307767474 corp cusip"
};
Preferred method:
private string[] _securities = null;
foreach (DataRow row in dsSecuritiesDetails.Tables[0].Rows)
{
//something to add here to add to the string array...
//i.e. _securities.Add(row["field2"].ToString()) + " corp cusip";
}
|

string[] _securities = null;
_securities = new string[]
{
"XS0166639566 corp cusip","XS0184546371 corp cusip", "XS0307767474 corp cusip"
};And then, whenever you need to add a string:
Array.Resize<string>(ref _securities, _securities.Length + 1);
_securities[_securities.Length - 1] = "The new string";
</string>

No, please don't do that.
There is no way of resizing an array in .NET. What the Resize method does is to create a new array with the desired size and copy all the data from the old array.
If you do this in a loop, the performace degrades exponentially to the number of items.

It was not about performance, why are you so upset?
He could use the StringCollection, but he simply wanted to use the string[] (I don't know why, ask him for that  ). I just offered a solution to what he wanted.
Peace

I'm not upset. I just wanted to point out that the solution is generally a bad method to use.
Eventhough the question didn't mention performance, some solutions scale so badly that they should never be suggested without explaining what happens when you use it with more than a minimal set of data.
Mircea Puiu wrote: I just offered a solution to what he wanted.
No, you offered a solution to what he thought that he wanted.
Just because he asked for it doesn't mean that it's the method that he should use.
People often don't know what to ask for. It's quite common that they ask for the solution that they think that they should use rather than a solution to the actual problem that they have.
