Solution 1

There is no built in mechanism for saving a run-time created form: you will have to do it manually by traversing the form Controls collection recursively and saving the info you need to rebuild it in your application later (or by constructing "savable" information when you build the form at run time).

We can't help you much: we have no idea about your program and how it works.

i am using this

Dim newform As New System.Windows.Forms.Form
newform.Text = txtfrmnme.Text
newform.Show()

in this code this is just creating a form but i want to save in my project also with the name of form i have given in textbox

The form is already created in your project - all you are doing is creating an new instance of it in your code. You can't "add that to your project" because it isn't a new design-time object - it's an instance of the existing design time form and it needs code to actually make it visible.

What are you trying to achieve (not what are you trying to do to display it, but why are you displaying it)? There may be a better way to do what you want.

Please give me any reference or example to solve this problem

OriginalGriff 19-Aug-14 5:25am

I can't "solve your problem" because I don't know what your problem is: I suspect you are trying to do something completely the wrong way, and until I know what you are trying to achieve, I can't suggest anything that will help.

OriginalGriff 19-Aug-14 5:41am

No, sorry.
Try to explain it.

Member 11014751 19-Aug-14 5:50am

when i run my program it display a form there is a fields Text-box for giving name to new form when i will write the form name on text-box and click on button create-form so it is just showing a new form named textbox.text but it is not saving in my project ...

OriginalGriff 19-Aug-14 6:03am

Right - so you don't want it in your project because that means you need to ship Visual Studio and your complete source code with each copy of the application!

What you really want to do is save the form name(s) and open the form istances next time you run your app - which is a different thing, and a lot simpler.

Start by adding Settings: Open your project, and the "properties" branch in the Solution explorer, and double click on "Settings.Settings".
In the page that opens, create a new setting: Name = Forms, Type = string, Scope = User, Value is blank.
Save the page.
Now in your main form load event handler, read the string:
Dim allForms As String = Properties.Settings.[Default].Forms
Dim forms As String() = allForms.Split(";"C)
For Each formTitle As String In forms
Dim f As New Form()
f.Text = formTitle
f.Show()
Next

That way, you can have as many forms as you like, with the titles separated by semicolons.

Hope you understand what i am trying to say ......

Member 11014751 19-Aug-14 6:21am

It is giving error on properties.setting.....

property is not declared. it may be inaccessible due to its protection level

OriginalGriff 19-Aug-14 6:27am

Did you add the settings?

Member 11014751 19-Aug-14 6:27am

YES

Member 11014751 19-Aug-14 6:39am

Now what do i do ?

Member 11014751 19-Aug-14 6:40am

i am using visualstudio 2012

OriginalGriff 19-Aug-14 6:42am

OK, try using intellisense:
Type the part up to the "=", and then start on "Properties" - it should appear for you.
If it does, add the "." and start of "Settings", and so on.
Which part doesn't appear?

Member 11014751 19-Aug-14 6:47am

Sorry i didn't understand what to do ? :(

OriginalGriff 19-Aug-14 6:52am

Start typing the line:
Dim allForms As String = Properties.Settings.[Default].Forms
again from scratch, and see what part of it is being complained about...

Member 11014751 19-Aug-14 7:04am

Dim allForms As String = "till here it is OK" but when i start writing Properties there is no such property named properties

Member 11014751 19-Aug-14 7:05am

DO i have to import any Namespace ?

Member 11014751 19-Aug-14 7:14am

i have written like this
Dim allForms As String = My.MySettings.Default.Forms ( IT WORKS)

but there is no form saved in project

OriginalGriff 19-Aug-14 7:18am

Ah! Sorry - confusion between C# and VB... :blush:

No, there won't be: you need to add them to the property setting when you add the form (separating them with a semicolon) and use My.MySettings.Default.Save to store them first...

Member 11014751 19-Aug-14 7:26am

i am writing this but it is giving error

Dim allForms As String = My.MySettings.Default.Save

error : Expression does not produce a value.

OriginalGriff 19-Aug-14 7:46am

No, no... it's a different part of it...
There are two parts: The Form Load even which reads the strings and opens the forms, and the bit where you create the new form instances using your textbox. The second one of there needs you to add the title to the setting, and save the new value for later...
Dim allForms As String = My.MySettings.Default.Forms
allForms = allForms & ";" & "new title"
My.MySettings.Default.Forms = allForms
My.MySettings.Default.Save

See what I mean?

Member 11014751 19-Aug-14 7:44am

What to do please guide ...

Member 11014751 19-Aug-14 7:55am

I have written like this is it ok ?
But there is no form saved in my Project

Private Sub SaveForm()
Dim allForms As String = My.MySettings.Default.Forms
allForms = allForms & ";" & "Forms"
My.MySettings.Default.Forms = allForms
My.MySettings.Default.Save()
For Each formTitle As String In allForms
newform.Text = txtfrmnme.Text
newform.Show()
Next
End Sub

Member 11014751 19-Aug-14 8:17am

Any Changes in this ?
