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!

Hi..
I try to insert 2 textbox text in one field but i face a problem please help me
my code is
SqlConnection conn = new SqlConnection(connString);

MessageBox.Show("Record Inserted.");
}
finally
{
conn.Close();
}
Error IS
perator '&&' cannot be applied to operands of type 'string' and 'string'
|
|
|
|
|
Ofcourse, && is Logical AND operator.
You can use + operator to combine two strings. 
|
|
|
|
|
What are you trying to acheive?
If you want to concatenate two strings, then use the '+' operator.
qty.Text + rate.Text
|
|
|
|
|
Thanks For Good And Fast reply

Dear friends ,
I have Problem like these ...
i have C++ dll which returns "unsigned char *" - this contains image data
now i want that to be converted to c# "byte[]"
how to do that???
thank you
|
|
|
|
|
|
Dear friend
thank for the reply
and few clarification,
"unsigned char *" is a pointer array and is it possible to assign to simple char[] of c# without any address as such ??
unsigned char* buffer = new unsigned char[xSize*ySzie]; //Type in C++
byte[] ImageData =buffer; //C#
throws error as "Cannot implicitly convert type 'byte*' to 'byte[]",
do i need to change byte[] ImageData to byte[]* ImageData
Thank you
