I do this all the time, so much so that I create a method the inserts a row at position 0 in the data table. Create a new row based on the table, populate it (relevant fields only) with your default value and use table.rows.insert.
public static DataTable TableAddRow0(DataTable oTable, int iLabelCol, string sLabel)<br />
{<br />
try<br />
{<br />
DataRow oRow = oTable.NewRow();<br />
if (oTable.Columns.Count > 1)<br />
{<br />
oRow[0] = 0;<br />
oRow[iLabelCol] = sLabel;<br />
}<br />
else<br />
oRow[0] = sLabel;<br />
<br />
oTable.Rows.InsertAt(oRow, 0);<br />
return oTable;<br />
}<br />
catch (Exception)<br />
{ throw; }<br />
}

Hi,
I am using Visual Studio 2008, i am writing a small code for Net Compact Framework. I use Windows Mobile Emulator. Now my code is in Directory "c:\Works\UI\MyProj". Now when i use following command
string path = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase);
it returns \Program File\MyProj instead of "c:\Works\UI\MyProj". I want to access another folder in the same directory called Images. I use something like this
MyImage = new Bitmap(path + @"\Images\myImage.bmp");
but when i try to execute the aove statement it returns the following error
Could not find a part of the path '\Program Files\MyProj\Images\myImage.bmp'.
How do i access the Images folder in my project directory 
Regards
Hiten Parmar

Check out the System.IO.Path class. Specifically, you may find Path.GetFullPath() and Path.Combine() useful.
If your image is located in a subdirectory in the directory of your app, you could just do
MyImage = new Bitmap("Images\myImage.bmp");. You don't need the full path there.

Hi everyone,
Iv'e created small application that sends files to a server using ftp.
I got 2 network adapters on my machine.
when i monitoring the communication i see that each time a different network adapter is sending the package.
My question is can i select which network adapter to use in the code level (if yes how) or it should be a netwok setting.
thanks in advanced

Hi
I had an application of BHO. It had been developed using visual Studio 2005. Actually, it main aim is to read the text of HTML page and write that into a text file. I had checked this on IE6 and IE7 in various PC's. before that I had installed .Net Framework 2.0 also. If I register that dll in some pc's it works perfectly on both IE6 and IE7. but on some PC's it doesn't write the html page's text into a file? what may be the problem?
How on earth can I figure out why there is a difference? I have compared tools>internet options>advanced. The settings on both computers are identical. They also both have all 4 security zones at the same level and they both have the same general settings.

hello
VBA calling C# code anyone? I'm looking for an article/tutorial.
Thanks

Thanks - seen better ways to do this (than wrapping it in COM/ATL server) now with Excel 2008?
I remember I done ATL server way back don't like this. You've got to marshall data into BSTR and all that (even thrown out the book now), just don't like the mechanism.
For example, this looks about right: http://www.c-sharpcorner.com/UploadFile/jodonnell/Excel2003fromCSharp12022005021735AM/Excel2003fromCSharp.aspx[^]
This article shows you how to generate Excel doc with C#, setting cell value via Excel object model and all. But still to call say C# component/dll from Excel VBA code... seems like COM is the only way?
But

COM isn't ideal, but I don't know any other options unfortunatly. The example you posted seems to be about replacing VBA in Excell with C#. I doubt that you're looking for Excell-automation-article's, so that's not going to help either.
Seems COM is the way to go, sorry

haha - COM is still alive afterall.

Neither do I, and I've looked in the past. On the plus side as long as you keep your types within the allowed values on the .net side (this doesn't cause any sort of compile time error, the method's just not exposed in COM) all you really have to do is to tell the compiler to make it a com class. From proof of concept testing, it's reasonably painless.

Dear all,
I have a procedure that works nice I guess.
Exm-
CREATE PROCEDURE Insert_TeacherProfile
(@Ins_ID int, @Yr smallint, @Querter int, @Tcr_ID smallint, @Tcr_Nm nvarchar,
@Gender smallint)
AS
INSERT INTO TeacherProfile
(Ins_ID, Yr, Querter, Tcr_ID, Tcr_Nm, Gender)
VALUES
(@Ins_ID, @Yr, @Querter, @Tcr_ID, @Tcr_Nm, @Gender)
Now you can see the all field not allaw null except Gender(allaw null) field. But In the software when I pass no (null) value in Gender filed it show error. Anyway to pass null value in this query. I need two option, value or null anything I can be inserted. Is there anyway to do it inside this procedure?
If you dont understand tell me.
Thanks

WE have a SQL forum, but if you want to be able to pass null in then use isnull to change the nulls to a default value.

NOt sure how you are passing a null value to the gender field - show us the code and we may be able to help - also what is the error you are getting?

It is not clear. Are you looking for solution to pass NULL to the @Gender parameter? If yes, you can do this in procedure level or in code level. In procedure level,
CREATE PROCEDURE Insert_TeacherProfile
(
@Ins_ID int,
@Yr smallint,
@Querter int,
@Tcr_ID smallint,
@Tcr_Nm nvarchar,
@Gender smallint = NULL)
AS
.... Or use DbNull.Value as parameter value from the code.
yourCommand.Parameters.AddWithValue("@Gender",DbNull.Value)
|
|
|
|

I know this coad that you mentioned.
i also using this coad. My need is by using this coad when it dones get any value from textbox the procedure automatically get null.
Is it possible??
|
|
|
|
|
well if you textbox entry is stored in an integer
e.g. int gender = SomeMethodThatConvertsTextToAnInteger(myTextBox.Text);
you could make gender a nullable int
int? = SomeMethodThatConvertsTextToANullableInteger(myTextBox.Text);
then when you pass that value to the SP (using the code supplied earlier in this thread) its value will be null.
Or you can say somethiong like
if (myTextBox.Text == string.Empty)
yourCommand.Parameters.AddWithValue("@Gender",DbNull.Value);
else
yourCommand.Parameters.AddWithValue("@Gender",myTextBox.Text);

thanks but I have also done this method.
My original code is this that U have adviced but I want to do this job by procedure. SO that I dont have to code all this line or use if else.
Thanks anyway.

Sorry, I am not really following what you are trying to do. You must pass teh parameter to the SP (because you may give it a value) so you need to pass some value (even if it is null) to the parameter - there's just no getting away from that.
