Textbox accept numeric values only

[neera]

I am trying to make a textbox accept numeric values only and the
target device is Treo700w using WM5.

I have tried that with suggested SetInputMode() method and used the
code given in http://www.devx.com/wireless/Article/21291

I am not getting any error but not able to do that .
Is there anything else that we have to set for using SetInputMode()
method?

Thanks.

SetInputMode() should actually do the trick. If you use .NETCF 2.0 or higher
then theres no need to wrap it yourself (as demonstrated in
http://www.devx.com/wireless/Article/21291). Its included in the
Microsoft.WindowsCE.Forms namespace

Neera,
As Christian mentioned, there is no need to write a wrapper to do
this.
Check out these links,

Hope this helps,
Cheers,

Treo 700W is actually based on Pocket PC Platform instead of a
Smartphone platform. Although its referred as Smartphone by Palm and
we need to input 2 in the textbox when we press 'R' on its physical
keyboard as its used to type 2 in numeric mode after pressing the alt
key.

So we need a Pocket PC compatible code. Please let us know if any of
you have any suggestions.

// Get the handle

this.Capture = true;

IntPtr hWnd = GetCapture();

this.Capture = false;

int lStyle = BaseTextBox.GetWindowLong (hWnd, GetWindowLongParam.GWL_STYLE);

lStyle |= (int) es;

BaseTextBox.SetWindowLong (hWnd, GetWindowLongParam.GWL_STYLE, lStyle);

----------------------

public enum GetWindowLongParam

{

GWL_WNDPROC = (-4),

GWL_HINSTANCE = (-6),

GWL_HWNDPARENT = (-8),

GWL_STYLE = (-16),

GWL_EXSTYLE = (-20),

GWL_USERDATA = (-21),

GWL_ID = (-12)

}

public enum EditStyle

{

ES_LEFT = 0x0000,

ES_CENTER = 0x0001,

ES_RIGHT = 0x0002,

ES_MULTILINE = 0x0004,

ES_UPPERCASE = 0x0008,

CF 2 and onwards exposes property Handle which returns the IntPtr (hwnd) of
control, not need to capture anymore.

Thanks for your suggestions. I have tried with the given code That is
also so much helpful for me. But what I am trying to do is whenever
the key for 'E' will be pressed, '2' should be entered. by the given
code I can validate textbox for not accepting any character , only
number will be accepted but for that I have to press one extra key .
That extra key press I want to remove.

Please give some direction to solve the problem.
Thanks a lot.
