Modify your code like this;
Control myCon = new Control();<br />
if (textBox1.Text == "")<br />
myCon = textBox1;<br />
if(myCon!=null)<br />
myCon.Focus();

It's not that your question is not detailed enough - it is that it is too broad a question to easily answer in one post.
You are asking about generic database connectivity, which can be found for looking at the ADO.NET documentation, or any number of articles written about database access.

Hi,
In the web application(C#) that i am developing, I use a javascript prompt window.
I need to get the value that is entered in the prompt window to a label control in the C# web form.
I could get the value into a text box using javascript code as:
document.getelementbyid('textbox1').value=-----
but if I try to get the value from the textbox to the label control(or from a hidden field), I am getting the value only after its posted back.Any solution for this?
Thanks,

I've been searching for some code to show how to print an image and scale it to the paper size and center it in the printable area. So far I've had no luck. Lots of examples on how to print text, but none for images. Does anyone have any examples, or know where a good example is?
Thanks.

Nobody knows how to print an image? Incredible.

If I write a pure C# application, only using the standart publi API, no interop, the same binary should work well on32 bit, 64 bits and perhaps on the compact framework as well if I link against it.
Now how could I achieve the same thing if I do interop and I have a managed C++ API?
let say I have a managed C++ module compiled for 3 different target but with always the same interface:
mycppmodule32.dll
mycppmodule64.dll
mycppmoduleCE.dll
let say in the C# code I also do some interop
internal class User32 // & CE ?!
{
[DllImport("USER32")]
public IntPtr GetHdc(IntPtr hWnd); // 4 byte IntPtr
}
internal class User64 // not sure it exists, but I assume....
{
[DllImport("USER64")]
public IntPtr GetHdc(IntPtr hWnd); // 8 byte IntPtr
}
Let suppose these DLLs are included as modules in my csharpdll.dll.
Now if I deploy all these DLLs, how could write a simple nice code in my C# dll which internally target whatever native lib is appropriate?
Is it possible (to keep it simple)?

Create a C# 'runtime' dll that you can conditionally compile. Then simply swap that out.

er...
thanks for answering!
what I was trying to do in a simple manner (if possible) is to have one library to run them all!
like imagine my program is a click once application, I would like (if possible) to avoid the x32 link, the x64 link, the CE link.
Just one link and it runs whatever the end-user machine.
Or also imagine the user "install" (i.e. copy) the file on one PC, and then he simply copy on an other PC and it sill works!
Conditional compilation is a clean way to have a build for a given platform.
But I wonder if there is a no hassel way to have one build for all platform that the user could simply copy without worrying about his pc's architecture....
you see what I mean?
is it possible? (in a simple way)
Note:
I did something like that on the PocketPC a while ago but it was akward.
Basically it was worked like that:
enum Platform
{
CE,
Win32,
}
public class OSUtil
{
internal static Platform Platform { get {} }
public Value AMethod()
{
switch(Platform)
{
case CE:
return OSUtilCE.AMethod();
case CE:
return OSUtilWin32.AMethod();
}
}
}
class OSUtilCE
{
static Value AMethod() {}
}
class OSUtil32
{
static Value AMethod() {}
}

No!
It didn't work like that, too simple!
Don't forget runtim verification when the method is launched, it worked like that:
enum Platform
{
CE,
Win32,
}
public class OSUtil
{
internal static Platform Platform { get {} }
public Value AMethod()
{
switch(Platform)
{
case CE:
return OSUtilCE.AMethod();
case CE:
return OSUtilWin32.AMethod();
}
}
}
class OSUtilCE
{
[DllImport("CEDll")]
static Value AMethodImpl();
static Value AMethod() { return AMEthodImpl(); }
}
class OSUtil32
{
[DllImport("Win32Dll")]
static Value AMethodImpl();
static Value AMethod() { return AMEthodImpl(); }
}
