Why don't you use the MySQL Connector for .NET 1.0.5 from MySQL.com ?

MSDE not connecting in windows 98

I have made windows application using .NET 2.0 BETA 2.0(VC#) with MSDE(Release A) as database tool. Now when I install my application on Windows 2000,XP,2003, it works well. But When I install on Windows 98, application is not connecting to database..
On command prompt, using OSQL, I can list database, table and I can connect to database. But When I try to connect throught application using connection string then it does not work.
Please help me sorting out this problem.
Thanks
1) Connection String is same in all O.S. version and it is SQL Auth.
2) I wrote following things in setup.ini of MSDE
[OPTIONS]
SAPWD="NILESH"
INSTANCENAME="NILESH"
SECURITYMODE=SQL
3) In Windows 98, I have used MDAC 2.8

MSDE client tools

Friends,
I've just installed MSDE in my machine for the first time. What i've seen is that it only installed Server and no client tools, unlike SQL server 2000.

Are there any client tools available for MSDE (like Enterprise Manager or query analyzer of SQL-server 2000). If not, then how can i manipulate the database of MSDE and create or view databases??

If you have a licence for the Sql server client tools, then you can use that.

Otherwise you are stuck with the commandline tools or 3rd party applications.

I like to use this[^] when I'm working with MSDE. Not as friendly as the MS tools but does the job well.

Fastest way to copy table in SQLServer 2000

Let's presume I have Table1 and Table2 already created and with same strucuture. Table1 has all data. So is this fastest way to copy data:

INSERT INTO Table2
SELECT * FROM Table1

?

Tnx

I think this is the fastest. You can try comparing the performance with

SELECT * INTO Table2 FROM Table1

If they are in the same database this should be the fastest or close to it.
If you have the transaction log configured to not log it, then using SELECT * INTO Table2 will create table2 and won't be logged which is faster.

Hi All!

THIS variable is in btnOK_Click() :
here is my code in Form1:

..... 
public int GetID; 
.... 
public void btnOK_Click(object sender, System.EventArgs e) 
{ 
..... 
GetID=Convert.ToInt32(UserTable.Rows[0][0]); 
.... 
}

I want to put (this value=GetID) into the another variable in Form2 that named :MyGetID in Form2_Load():
Here is my code on form2:

....... 
Form1 myform1=new Form2(); 
........ 
private void Form2_Load(object sender, System.EventArgs e) 
{ 
int MyGetID;
MyGetID=:zzz:(?GetID); 
.... 
... 
}

infact I want to put the value of GetID(the variable in Form1) into the MyGetID(The variable in Form2)
How Can I do it ...?
Please Help me!
thanks!

Many ways, all depends on timing... When do you need the value exactly Wink | ;-)

Static variable in form1..

public static int x;<br />
myID = form1.x;

or

Change the form2 constructor, declare a local private variable.
(Note: you can have multiple constructors).

Class Form2{<br />
    private int var;<br />
    Form2(int x){<br />
       var = x;<br />
    }<br />
}

in form1 create as

form2 f = new form2(x);

or

as a property
public int x{get(...)set(...)}

Hope that helps.

hi,dear friend!
Via to:

public static int x;
myID = form1.x;

because of "x" is variable in a Event(btnOK_Click()),
,myGetID return a value=0(Zero),
but,using a property in form1 and form2 , I can solve the problem .
thanks again!
yours!

Hi
I have a select statement that returns (A int ,B int)
and another select statement that returns (C int , D int)
in a storedprocedure.
I need that sp returns a resultset as (A,B,C,D);
What should i do plz?

You can combine the two queries as following,

select Select1.A, Select1.B, Select2.C, Select2.D
from
(select A, B from Table1) as Select1,
(select C, D from Table2) as Select2

Please note that this will give you the cross product.

if they are scalar values you are dealing with then just do this.

<br />
declare @a int,<br />
@b int,<br />
@c int,<br />
@d int<br />
select @a = 1, @b= 2<br />
<br />
select @c = 3, @d= 4<br />
<br />
select @a as ColA, @b as ColB, @c as ColC, @d as ColD

Else, if it is a rowset, then do what alam_pune said,
but pull a join column from each of the sub selects in
order to join the rowsets to avoid the cartesian product

<br />
<br />
select Select1.A, Select1.B, Select2.C, Select2.D<br />
from<br />
(select A, B, PriKeyCol from Table1) as Select1<br />
	inner join<br />
(select C, D, ForKeyCol from Table2) as Select2 on select1.PriKeyCol = select2.ForKeyCol

assumption in form2, u already had a form1 variable, named as m_frm1 and have a property to assign the value to this variable
before showing form2, u need to assign instance of form1 to the variable m_frm1

the code should be something like this

Form2 frm2 = new Form2();
frm2.Form1 = this; //this here is form1 object
frm2.showDialog();
