Hi,
add a form to your project. Add two textboxes to the form. Add a button to the form. Hook up the button's onclick event handler to retrieve data from the database and compare this with the data in the textboxes.
Best,
Morten

Hi,
You might required to reach the required cells/range of cells to format the cells.
Excel.Application excelApp = new Excel.ApplicationClass();<br />
Excel.Workbook excelWorkbook = excelApp.Workbooks.Open(File_Path,<br />
0, false, 5, "", "", false, Excel.XlPlatform.xlWindows, "",<br />
true, false, 0, true, false, false);<br />
Excel.Sheets excelSheets = excelWorkbook.Worksheets;<br />
Excel.Worksheet excelWorksheet = (Excel.Worksheet)excelSheets.get_Item(fileName);<br />
Excel.Range excelCells;<br />
<br />
excelCells = (Excel.Range)excelWorksheet.get_Range("A1", "G1");<br />
excelCells.Select();<br />
The above example code will select a range of cells from A1 (column name) to G1 (column name). Now you have range of required cells to apply any specific format.
Here let me explian some formating tips interms of Font style and name.
excelCells.WrapText=true;<br />
excelCells.HorizontalAlignment=Excel.Constants.xlCenter;<br />
excelCells.Borders.LineStyle=Excel.Constants.xlSolid;<br />
excelCells.Font.Bold = true;<br />
excelCells.Font.Size = 9;<br />
excelCells.Font.Name = "Verdana";

Hi,
In line with the last post, you can use this line of code to retrieve the value from a specified cell and use string format.
excelCells = (Excel.Range)excelWorksheet.get_Range("A1",Type.Missing); <br />
excelCells.Value2 = "File Name";

One solution of this problem is create a web service and communicating with SOAP.

Are yo trying to connect to it from the DB itself? As in from one DB to another that's on a different server? If so then you more appropriately it should be posted in the SQL forums.
If you're doing this from C# then, unless its on a different vlan, then you need a web service (definition: Clickety[^]). If its on the same lan (read network) then you need to be more specific in specifying your connection string by specifying the server name or the IP address (more on that here: Clickety 2[^])
Web Services are not .Net specific, so don't blame your lack of understanding on .Net. There are many articles here that explain Web Services and give you examples. Here, I'll do your lazy work for you: (Clickety 3[^])
You also might want to try the ultimate answer tool. I mean this Clickety 4[^] rather than anything else.

There are two options of doing that.
1. You can access it via our normal ADO.Net by creating the connection to that server and doing what you want on that server.
2. If your database server is MS SQL Server then you can create what is called a linked server... in this case you have to connect to you own server and fire select and insert queries on the remote server.
Hope this helps..

Hi, i have a requirement of online exam. Just all the question and answers are in Database and retriving them and showing on the webpage.
Suppose if the question contains a code snippent, how to store it in database and how to show the same format in webpage?
Ex: How to store the below code in database as it is?
public static void main()
{
MessageBox.show("code snippent");
}
|
|
|
|
|
you have to append new line (\n) character in your string
|
|
|
|
|
yes, it is correct to store data using "/n".
But, suppose user posting a codesnippent in discussion forum like(Ex: posting message with code snippent in codeproject). User types message in textarea and submit the post. When i am reading the whole data will get in one string. How can i separate it for new line?
Ex: string strmsg = txtArea.text.Tostring();
now the strmsg contains whole text. How can split the strmsg for newline. How i know where the new line occurs

hi guys
i have a class named abc_voucher and another class
derived from abc_voucher named def_voucher,
but in my application i have a function and its return type is
generic list of abc_voucher and i am returning from this function the generic list
of class def_voucher which is derived from abc_voucher , but it gives an comlite time error ,,
though my return object is derived from the type which i am returning in function's signature ,
why is that ?
thanks in advance

Are you extracting the def_voucher list from the list that you retrieved that has the abc_voucher list? Is that what you're doing?

no i am not extracting
def_voucher is derived from abc_voucher , but it gives compile time error
public function abc as list(of abc_voucher)
dim list as new list(of def)voucher)
'
function body
'
return list
end function

Hi,
Sorry to tell you that, i am not getting what you are trying to achive appart from some class relation.
namespace CS<br />
{<br />
class Program<br />
{<br />
static void Main(string[] args)<br />
{<br />
B Obj = new B();<br />
List<A> _list =Obj.GetList();<br />
}<br />
}<br />
class A<br />
{<br />
protected int Age=0;<br />
public A() { }<br />
public A(int age)<br />
{<br />
this.Age = age;<br />
}<br />
}<br />
class B : A<br />
{<br />
<br />
public List<A> GetList()<br />
{<br />
List<A> GList = new List<A>();<br />
GList.Add(new A(21));<br />
GList.Add(new A(22));<br />
GList.Add(new A(23));<br />
return GList;<br />
<br />
}<br />
}<br />
}
Presumably, the above lines of code will give an idea on the route map.
