depends on your definition of "blank line". Do you realy want to throw away a line holding a couple of spaces and/or tabs?

If you decide to use the suggestions made by others you might consider replacing
<br />
if(strdata == null || strdata == string.Empty)<br />
by
<br />
if (string.IsNullOrEmpty(strdata))<br />
It does the same thing, albeit 15 milliseconds more slowly, but IMHO it reads more easily.

wasn't a very good suggestion as the two cases need to be handled differently; a null indicates the end of the stream, whereas string.Empty is a line the OP wants to skip.

A valid point. However where legitimately testing for null or empty I still prefer IsNullOrEmpty().

That wasn't the hard part. Getting it to run under Windows 3.1 was more problematic.

I haven't played with 4.0 much yet so hadn't discovered that. Thanks for the tip.

It it's blank (and therefore empty, thus invisible), how do you know it's even there?

Hi
Here i am trying to do is i have one excel file has some data called emails.
Now i want to read that data from excel sheet and send to databese table.
How can i do it using c#.
try and try untill reach success..

There are several ways, probably the easiest is to read the excel file using ODBC - although you can also do this using SQL Server Manager and importing your data if its a one off load.

Hi Bob!!!

you can also upload excel file through SSIS which is included in MS SQL Server 2005.
|
|
|
|
|
1-set the database
2-if you want to show the process make DataGraidView and set it as the database
3-then copy all the data from excel file to DataGraidView
4-then each row insert it into data base
(there is a lot of articles in code project explain how to read write from excel file)

hi,
i have two forms and i m changing text of a control on second form from first form through a static property.now i show the second form but the text doesnt changes.wat is wrong?
|
|
|
|
|
Can you show your code?
Its difficult to tell what is wrong without seeing your code.
|
|
|
|
|
Post code or elaborate your question (preferably the first one ).
|
|
|
|
|
There could be so many things wrong, it is impossible to be definite. However, the first question for you is: why are you using a static property? You do realise that it is shared by all instances of the form?
Try using a public property on Form2, and use it in the form load event:
public string myText { get; set; }
...
private void Form2_Load(object sender, EventArgs e)
{
label1.Text = myText;
}
Then in Form1:
Form2 myForm = new Form2();
myForm.myText = "Hello World!";
myForm.Show(); If this doesn't solve your problem, then you will have to post relevent code fragments from Form1 and Form2 (enclosing in <pre>...</pre> blocks with the "code block" widget to preserve the formatting and make it easier to read) - don't just post your entire project, nobody wants to wade through loads of irrelevant code!
