Smart Device Framework Signature Panel - Draw Signature In Full WinForms App

May 15, 2011

I'm planning on using the Smart Device Framework 2.3 to use the signature control panel in a Windows Mobile 5 application using the compact framework 3.5.

The control has the option to save the signature as either a byte array of points, or as a bitmap. Now seeing as I want to store the signature in a sql compact database, I guess the byte array is going to be better. The trouble is, I'm not sure how to render that in a full WinForms application after I've transferred it back to the desktop.

I need to show the signature on a report, so it would need to be an image I could link/embed into the report.

Add Controls Dynamically And Display Information In Them On Windows Form?

Oct 4, 2009

Just like an array in a group box or a frame as i used in vb6.

If there are 5 customers details then when i load the form it will add (PictureBox, Label and a listbox) for each customer dynamically and display them with their information. Moreover, if i add 6th Customer information in the database then next time i load the form it should display his/her information as well. I did this in VB6 sometimes back but need a start to do in .net

Private Sub LoadCustomerInformation()
Dim Qry As String
Dim RS As New Recordset

Using A Lambda Expression With ByRef Argument Gives Incompatible Signature Error

Mar 9, 2011

Why does this:Private [Function] As Func(Of Double, String) = Function(ByRef z As Double) z.ToString

gives the following error:Nested function does not have a signature that is compatible with delegate String)'.

While this:Private [Function] As Func(Of Double, String) = Function(ByVal z As Double) z.ToString

Does not? (The difference is ByRef/ByVal)

Furthermore, how might I implement such a thing?

.net - Some Kind Of Error, Possibly When Viewing A Windows Form In The Designer?

Jun 24, 2009

I though I had solved this problem, but it is back:Code generation for property 'SelectedPeople' failed. Error was: 'Type 'ECS.Entities.Persistency.Person' in Assembly 'ECS, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' is not marked as serializable.'The property on the error message is a List(Of Person) and for some reason it trigger this error, for almost anything I do, and its getting really anoying.Okanswering to the answers here is a little more information about the problem.

Yes it is during design time, it happens bascially anytime a open a form that has a UserControl that contains the Selected property in it, sometimes it happens even if I don't have focus on the form, also if I try to compile/run it happens and the message come in the form of a Message Box with just a OK, ECS.Entities.Persistency.Person is just a LINQ to SQL Generated Class, this should not matter at all to the problem, although I have added the attribute before the posting.he reason that this happens is because the Designer attempts to put the property on the Property Panel, and for that to happen, serialization happens.tryed to hide the property from the designer by using this attributes.

<DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)> _
<Browsable(False)> _
Public Property SelectedPeople() As List(Of Person)

How can this be done?

Try

'some code taht will throw an error'

If ex.ErrorCode = 20 then

Determine If A Form Is Already Open In SDI Application?

Feb 2, 2010

My program has many forms that can be launched from the main form, and when launching a form, I need for my program to know whether or not there is already an existing instance of the requested form open before it launches the requested form.

So, if I have form "Search" with button "View" that launches form "Details", I need to know if the "Details" form is already open when the user clicks the "View" button.

Apparently, if I had developed my application as an MDI application intead of an SDI application, I could just do "If frmDetails.visible = True then DoStuff()", but the Details form's Visible property always comes back as False, even when the form is already open. If the form is always being reported as not being visible even when it is indeed visible, what method do I use instead to find out that the form is open/visible/in use?

Determine The Top Most (zOrder) Window Other Than The Form?

Dec 21, 2011

im trying to find the top most window other than my form or its parent form...Background:Im writing software for a TS-MFD (touch screen - Multi function display), it has a docked menu bar at the bottom with the option to pull up an onscreen keyboard. Now the keyboard ive written and works well but the only drawback is i need to specify what window to send the keys too, be it inside my own application or a 3rd party app such as notepad. I believe the answer lies an recursively looping through GetForegroundWindow() from user32.dll and ignoring "Keyboard" and "MenuBar", but I dont know how to advance to the next top most window, i only know how to get the top window...so my window order is likely Keyboard,Menubar,(then the window im trying to grab)?

Determine Which Control Called A Form?

Mar 3, 2010

I have three buttons on my main form, say Form1. Clicking any of the buttons brings up Form2 modally for input, it's a number pad. Now, depending on which button was clicked to get there, after the user enters his numbers, I need to change a specific label on Form1. In other words, btn1 clicked puts user input into lbl1 and so on... I could probably do this with a variable but wondering if there is a more elegant way.
