But after run the solution, then stop and exit it and then try to enter designer the exception appears again and again until restarting VS. But I found the solution for it - everything to do is add below to your app. Since the abstract class public abstract class BaseForm: Form gives an error and avoid the use of the designer, I came with the use of virtual members.
Basically, instead of declaring abstract methods, I declared virtual methods with the minimum body as possible. Here's what I've done :. Since DataForm was supposed to be an abstract class with the abstract member displayFields , I "fake" this behavior with virtual members to avoid the abstraction.
The designer doesn't complain anymore and everything works fine for me. It's a workaround more readable, but since it's not abstract, I have to make sure that all child classes of DataForm have their implementation of displayFields.
Thus, be careful when using this technique. That's why you can design the form created by the project wizard without even building the project. Because of this behavior you also can not design a control derived from an abstract class. You can implement those abstract methods and throw an exception when it is not running in the designer.
The programmer who derive from the control must provide an implementation that does not call your base class implementation. Otherwise the program would crash. You could just conditionally compile in the abstract keyword without interposing a separate class:.
This works provided that BaseForm doesn't have any abstract methods the abstract keyword therefore only prevents the runtime instantiation of the class.

NET Framework template, you can install it from the Create a new project window. In the Not finding what you're looking for? Next, in the Visual Studio Installer, choose the.
NET desktop development workload. After that, select Modify in the Visual Studio Installer. You might be prompted to save your work. In the Configure your new project window, enter HelloWorld as the Project name. Then, select Create. After you select your Visual Basic project template and name your file, Visual Studio opens a form for you.
A form is a Windows user interface. You'll create a "Hello World" application by adding controls to the form.
In the Appearance section of the Properties window, for Text , type Click this , and then press Enter. If you don't see the Properties window, you can open it from the menu bar. If you've alphabetized the list in the Properties window, Button1 appears in the DataBindings section, instead. And all required prerequisites are selected automatically.
But if you want, you can either add or remove them from your prerequisites setup. Updates In this window, you should define how your application should be updated. Check 'The application should check for updates' and choose whether it should be updated before or after the application starts. If you choose to update it after running the application then you can mention whether you want to check each time it runs or can mention a time period, that it should check.
But it is always advisable to check before application starts, so users will get the latest updates each time they run the application. And specify a minimum required version, so that the end user will get the specified version of the application, if they have an older version installed on their PC.
If the updating location is other than the publish location then please provide the path. Save the settings and go to the form designer and add a label to the form. Save and go to "Build"??? If you wish make any changes to the publish settings that you completed earlier then click "Next" or click on the "Finish" button. Click "Next". And the deployment setup will be created in the published path.
