i tried to display the value "ImportStandard.ToString() " using messagebox it returned 1 only.
can u please tell me some other alternative.
|

This is an alternative:
MessageBox.Show(Enum.GetName(typeof(enumCatalogExportStandard ), ImportStandard));
But... it is impossible. The code:
enum alph { A, B, C }
alph ph = alph.A;
MessageBox.Show(ph.ToString());
gives me "A"... Please post the full code.

hi Gajatko,
i don't know why any alternative is not working in my m/c.
when i tried
MessageBox.Show(Enum.GetName(typeof(enumCatalogExportStandard ), ImportStandard));
gave me a null string as output.
i am sending the code snippets where ever i am using the enum related stuff in my code pls view.
public enum enumCatalogImportStandard { CatccImportAsISO, CatccImportAsFGDC, CatccImportAsNative };
enumCatalogImportStandard ImportStandard;
private void cmbTargetstd_SelectedIndexChanged(object sender, EventArgs e)
{
if (cmbTargetstd.SelectedItem.ToString() == "ISO")
ImportStandard = enumCatalogImportStandard.CatccImportAsISO ;
else if (cmbTargetstd.SelectedItem.ToString() == "FGDC")
ImportStandard = enumCatalogImportStandard.CatccImportAsFGDC ;
else if (cmbTargetstd.SelectedItem.ToString() == "Native")
ImportStandard = enumCatalogImportStandard.CatccImportAsNative;
}
private void btnApply_Click(object sender, EventArgs e)
{
CImportCatalogRecordService.ImportCatalogRecordService objImpRecService = new CImportCatalogRecordService.ImportCatalogRecordService();
//below statement returning number instead of string
objImpRecService.ImportStandard = ImportStandard;
objImpRecService.InputFileName = txtImportFolder.Text + "\\" + Rec;
objImpRecService.CatalogConnection = con;
objImpRecService.Execute(out MetadataID);
}
this is all my code Pls view.

Of course it returns a number. Change it to:
objImpRecService.ImportStandard = ImportStandard.ToString();

Hi,
Please consider the following interface in C++.Net
<br />
public __interface IAnimal<br />
{<br />
void Eat(String^ food);<br />
};<br />
when I try to implement this in a C# class...
class Dog : IAnimal<br />
{<br />
...<br />
}
It gives me an error "error CS0509: 'Dog': cannot derive from sealed type 'IAnimal'"
What am I doing wrong here?

Your definition of the IAnimal interface is incorrect. Try:
public interface class IAnimal {
void Eat(String^ food);
};
Take care,
Tom

Hi All,
I have one HTML Table. Table has 3 rows and 2 columns. It is just like this:::::
COL 1 COL2
+++++++++++++++++++++++++++++++++
Label1 Label1.Text
Label2 Label2.Text
Label3 Label3.Text
+++++++++++++++++++++++++++++++++
Now I want to take this information into DataTable by dynamically adding columns and rows to DataTable. Means in the 1st column, name of the labels and in the 2nd column,Labels's Text field. Plz give me the idea about it.
I m working on .net 1.1 + c#
Thank you............
Keep Smiling...........

You've answered your own question. Now all you need to do is write some code.
The MSDN documentation[^]shows you how to do this.

Hi Paul,
Thank you for reply. I have tried this code. But it gives me error.
<br />
DataTable dt3 = new DataTable();<br />
DataColumn dc1 = new DataColumn("Col_1",System.Type.GetType("System.String"));<br />
DataColumn dc2 = new DataColumn("Col_2",System.Type.GetType("System.String"));<br />
for(i=0;i<=2;i++)<br />
{<br />
dr = dt3.NewRow();<br />
dr["Col_1"] = "TOTAL less GST";<br />
dr["Col_2"] = lbl_total_less_GST.Text; <br />
dt3.Rows.Add(dr);<br />
} <br />
<br />
dt3.Columns.Add(dc1);<br />
dt3.Columns.Add(dc2); <br />
<br />
can you plz tell me where I m wrong???
Thank you
Keep Smiling ...............

Hi Paul,
Thank you for reply again. But I have done this like following:
<br />
DataTable dt3 = new DataTable();<br />
dt3.Columns.Add("TOTAL less GST");<br />
dt3.Columns.Add("GST"); <br />
dt3.Rows.Add(new string[] {"TOTAL less GST",lbl_total_less_GST.Text});<br />
dt3.Rows.Add(new string[] {"GST",lbl_GST.Text});<br />
dt3.Rows.Add(new string[] {"TOTAL",lbl_TOTAL.Text});<br />
Actually my table structure is static only label's text is variant. So i have done this.
thank you.
Keep smiling........

You're original code didn't make logical sense and there were undefined variables which prevented it from compiling.
I changed it to the following, which works:
DataTable dt3 = new DataTable();
DataColumn dc1 = new DataColumn("Col_1", System.Type.GetType("System.String"));
DataColumn dc2 = new DataColumn("Col_2", System.Type.GetType("System.String"));
dt3.Columns.Add(dc1);
dt3.Columns.Add(dc2);
DataRow dr = dt3.NewRow();
dr["Col_1"] = "TOTAL less GST";
dr["Col_2"] = lbl_total_less_GST.Text;
dt3.Rows.Add(dr);
dr = dt3.NewRow();
dr["Col_1"] = "GST";
dr["Col_2"] = lbl_GST.Text;
dt3.Rows.Add(dr);
dr = dt3.NewRow();
dr["Col_1"] = "Total";
dr["Col_2"] = lbl_TOTAL.Text;
dt3.Rows.Add(dr);

You must add DataColumn objects to a table before you bind to them. Also you have another error which will not be catched by any compiler. Make meaningful names! Col_1 and Col_2 tells nothing!
I would do it like this:
DataTable table = new DataTable();
table.Columns.Add("Name", typeof(string));
table.Columns.Add("Text", typeof(string));
DataRowView dr;
for (int i = 0; i < 10; i++) {
dr = table.DefaultView.AddNew();
dr["Name"] = "Name " + i.ToString();
dr["Text"] = "Some text no. " + i.ToString();
}
table.AcceptChanges();

Is the "double" type is faster than "float" type in .Net when using them in loops?
I sensed in my experience that it is true. somebody has any idea about it?
and why it must be true?
thank you

double and float have different precisions. Performance is not something I've ever taken into consideration when deciding to use one over the other.
I'm guessing that if you've seen double as being faster it is probably because the processor's native floating point representation is a double and floats (although they save memory) will be slower as a result because the processor converts them internally to doubles, processes it then converts it back. But, that is just my guess.

I think you are right.

That would be to line up on the word boundaries, I've always thought.

Hi Paul,
I am sure it is not related to memory alignment: double alignment is not
more relaxed than float alignment. If there is any difference in performance, one
should have a look at actual code (assembly rather than MSIL); it could prove
Colin's guess is right.

Hmmm, I think I might just write up a quick little app to do a fun little weekend investigation

Hi Paul,
any interesting results in your float/double perfo investigation?

Nothing really outstanding at this point. Seems to be a push between the two.

It's correct that the processor does all operations internally using doubles. Which ever type is faster also depends on several other factors, though. If you for example process an array of numbers, floats may be faster than doubles just because more of them fits in the processor cache.

Hi
for floating point operations Double is the most efficient type because those operations are optimized by hardware.

thank you all.
look at these codes
1.
for(int i=0;i<100000000;i++)
{
float f1=i/357;
float f2=i/546;
if(f1>f2/3454)
{
f2=f1;
}
}
2.
for(int i=0;i<100000000;i++)
{
double f1=i/357;
double f2=i/546;
if(f1>f2/3454)
{
f2=f1;
}
}
the first code consume 7.27 sec and second code consume 6.73 sec in my computer.
of course assignment statement is high time consumer.
somebody has any idea about it?
