Create Dynamic Controls and Displaying Page by Page on the form

P: n/a
Esteemede Developers,

I would like to Thank All of You in advance for your sincere guidances.

I am developing a software using Visual C++ .NET Standard Edition with
Windows Form (.NET) template.

Briefly
--------------------------------------------------------------------------------------------
I need to create dynamically some controls on the forms, and display these
controls page by page on the form by using "Previous Page" and "Next Page"
buttons.

In detailed
--------------------------------------------------------------------------------------------
I will read some information from a file. The contents of this file include
Parameter information line by line. Each line is formatted. We may think
that, this file is a Table with some columns of a database.

Format of each line is similar to following:
Param_Number;Param_Name;Default_Value;Unit;Info1;

Firstly, I will read this file and determine how many rows exist. Then, I
will create dynamically some controls for each line. Dynamically created
controls are as below:
1. Param_Number : Label
2. Param_Name : Label
3. Default_Value : Label (contents of this field will change during the
running of application)
4. Unit : Label

This group of controls will be created on the form dynamically.

The number of rows ( number of parameters) may change file to file, but
row data format will be same.

My form's size will be maximized. I want to create control groups as much
as on the form one under the other. Let's say the number of parameter is
1000, and It is possible to dynamically create 50 control groups on the form.
This means than it is required to create 20 different pages on the form.

These are my questions...!!

**** How can I create dynamically controls on the form? ,
**** How can I show them page by page on the form.? and
**** How can I go through on the pages with "Previous Page" and "Next
Page" buttons?

I will receive some parameter values from TCP/IP socket periodically.
Therefore I have to change the received parameter values at the related
Labels in each page on the form.

I am requesting you to guide me ...

With this, I extend you and all yours with my bests.

Respectfully, yours

Bil Muh

This is VB.NET but I coded for 2 years in C++ and know this should make more
than enough sense to help you.

1. The first thing I always do is put a panel on my form.
You will stick all your controls on that panel, lets call it pnlMain.

Now create an object of your control. Lets say I want to put a checkbox on
there.
Dim oObjCheckBox As CheckBox = New CheckBox()
Give it all the attributes you want to give it
oObjCheckBox.ID = "chkIDOne"
oObjCheckBox.Text = "vbIsForGirlsandCPPRule"
Now stick it on your panel
pnlMenus.Controls.Add(oObjCheckBox)
You can put this in your onload, but just check for postback, otherwise you
will lose youre changes on your controls. If you can do this (which should
be very easy) the rest will be easy as well. Put controls on your panels and
managed it from there

Hope it helps a bit, an if anything is not clear or if I misunderstood
you...just reply

I thank You so much, Joe.

Your guidance will help me during my solution.

Please do allow me to ask my questions. Can you explain a bit more about
"postback" ? I could not understand what does it mean.

Is there some specific reason why you don't want to use a DataGrid control ?

I'm saying this because dynamically creating a few thousand controls might
turn out to be a real performance killer for your application, no ?

If you construct a DataSet from your file ( or stream or whatever ) and
fiddle a bit with a DataGrid you could possibly do paging very easily.

Actually, there is not any specific limitation in my application. Please let
me explaing my intention.

There is a one file that contains formated rows of data pertaining
parameters. The number of rows will not be fixed. Let's assume there are 1000
parameters in that file.
I am communicating with another computer via TCP/IP. Both computers have
the same file. My computer is client and other is server. Server generate
values for 1000 parameters and sends them to the client periodically.
At the client side, I want to display all recevied values for parameters
as quick as possible. I thought that having a Paging style display would be
user-friendly to observe the data. Due to having hundreds of parameters, I
want to display them page by page. But other solutions are acceptable.
My constraints are simple:
1) Be Fast,
2) Show All,
3) Enable dummies to understand immediately, how to observe other
parameters, that are not on that page...

For every parameters, I have to show the followings on the form:

Parameter_Name Parameter_Current_Value Parameter_Unit

That's all...

Can you explain me how to use DataGrid to display values Almost-Real-Time
in the cells and How to show them similar to Page by Page type, please?

My Best Regards...

First, you can create a DataSet instance.

Add a DataTable, with Columns: Parameter_Name Parameter_Current_Value
Parameter_Unit
... and then add a row for each line from your feed.

Conceptually, it's more or less the same as creating 3 Labels at the time,
the only real difference is that you can bind
the DataSet to a DataGrid control, and have the grid display the data
page-by-page.

I'm no expert on Windows Forms Controls like the DataGrid, but I do believe
strongly that with a little work you can get much more done with the
DataSet - DataGrid combination than by adding labels arbitrarily on your
form.

Sorry I couldn't be of more assistance,

I coded an example for dynamic control creation. You may find the source
codes below:

1) This source codes are for Visual C++ .NET v.2003
2) Open a project by using "Windows Forms (.NET)."
3) Name the project as : "Panel_Denemeleri"
4) Paste the below source codes to "Form1.h" code view.
5) Compile, Debug and Build the program :)
