PasswordTextBox

[Cableguy]

Here's my 2nd dll

A PasswordTextBox....

This Textbox enables the coder to hide the input string using a character like "X" or "*", so that no-one can peek at the string...
and in this case I also implemented a simple encryption of the string passed back to the main basic4ppc code...Of course there's also an un-crypted string that can be passed....
This was only tested in the desktop...
This is also a work in progress, and probably will evolve to a Password Panel Input...

Please place your doubts, wishes or any kind of comments....

Hi Cableguy,

I'll get an error adding your password.dll library on the dektop saying:

An error occured. The format of th file "password.dll" is invalid.
(translated from the german message :sign0013

By the way, any help file available? A small textfile will do.

Sorry,

yesterday's Post was set kind in an hurry...

Here is the dll, a sample app and a txt...enjoy

PS:
the password property is not supported by the compactframework but is suported by the "normal" framework,wich you should have installed in order to this dll to work...

 

[Erel]

If it isn't supported by .Net CF then it will only run on the desktop.

If I extract your .zip file and open the sample I still get the error saying that the .dll has an ivnalid format... :sign0161:

 

[Cableguy]

Specci48, do you have the dotnet framework ( not the compactframework ) installed in your PC...?

This dll, at least for now, is only supported in the desktop....

Has anyone else had similar problems with this dll?

 

[Cableguy]

I just don't understand Why this dll doesnt work on the ppc....

The msdn states the passwordchar to be supported by bot cf 1.0 and 2.0 but I cant even load it to the program....

[Erel]

The FormLib library now supports SetPasswordTextbox which does this.
It can be downloaded here: www.b4x.com/Downloads.html

I just don't understand Why this dll doesnt work on the ppc....

Looking at the references for the DLL with Reflector I think the reason may be that you have compiled it as a full .NET Framework 2.0 library and not as a retargetable device library.

 

[Cableguy]

Agraham You were Right!!!!

I didnt realize it, becausse my first dll was built on top of dzt example project, wich was, of course, already set to work with the compact framework....

Thanks...

Working now, but some features dont work the same way in ppc as in desktop

text alignment is set to center: works on desktop but not on ppc
passworchar shows what ever char is set on desktop, but in ppc is always "*"

Any clues???

 

[specci48]

Yes, the .Net Framework 2 is installed on my pc and it works fine with a lot of other programs. But if I open your "Controls" sample or add the dll to a new project I'll get the error.

I don't really need the password field and since Erel updated his FormLib...

But I'm still wondering.

Updated Lib, should work now

text alignment is set to center: works on desktop but not on ppc

No idea why this doesn't work as long as you have set "Textbox1.TextAlign = TextBox1.TextAlign = HorizontalAlignment.Center". This is documented as being supported in CF 1.0 and 2.0.

passworchar shows what ever char is set on desktop, but in ppc is always "*"

This is supported under CF 1.0 and 2.0 according the the VS2005 documentation. However if you are running under CF 2.0 the following applies :-
"UseSystemPasswordChar property (This property is new in the .NET Framework version 2.0) has precedence over the PasswordChar property. Whenever the UseSystemPasswordChar is set to true, the default system password character is used and any character set by PasswordChar is ignored."

 

[Cableguy]

Thanks Agraham..

I did target cf 2.0 so perhaps thats the reason for the passwordchar not showing, no big deal...
The text alignment is set like this (and works on the desktop)
tb.textalign = HorizontalAligment.Center
being tb the textbox control's name...

In the desktop it works fine, but on the ppc is stays aligned to the left..maybe as result of the previous property?

 

[Erel]

Only multiline textboxes support changing text alignment (on the device).

 

[Cableguy]

mistery solved....

 

[agraham]

Found this (at last) in the VS2005 docs. Explains both of Cableguys' queries.

Textbox in the Compact Framework
-----------------------------------

Single-line TextBox controls, specified by the Multiline property, support only left alignment. Multiline text box controls can be aligned left, right, or center.

If Multiline is false, the .NET Compact Framework sizes the control to the Height specification, but only the first line in the TextBox is usable. The full .NET Framework keeps the height to one line.

The PasswordChar property is always an asterisk (*), regardless of what is specified.

A few days ago I did some hard disk cleaning, installed Basis4ppc to another directory ... and forgot to copy Dbasic.exe.config ...

So sorry for my unnecessary posts.
