• Creating Accounting Application with C # - Part Two

In the previous article, we started our application development by creating the main window in MDI format. In this article, we will add some additional features to the form.

Flow of the article

• Open another window from Main Form as MDI child
• Forms used in this project and their use
• Storing data in Properties.Settings
• List of Properties.Settings.Default variables we used in this projects

Open another window from Main Form as Mdichild

First of all, let us add a form to the project. To add a new form to the project, put the cursor on the project name shown on the Solution Explorer. Right-click the mouse >> Add-New Item.

Or from the menubar, you can add the same by clicking Project >> Add Window Form.

Then, press on Windows Forms >> Window Form. After giving a suitable name, press OK button.

We have added a new form to our project. Now, we have to write the code to open the newly created form from the Main Window.

We can create an event. By creating an event, we are applying an action to the control. Firstly, select Firm and then double-click on Company Details. The system will automatically create an event for us.

Then, declare the form as given below.

Next, we can write full code as given below.

Here, with the ‘If statement’, we check whether the form is opened or not. If the result is null, we have to declare the class and if the result is not null, we just activate the CompanyDetails window. To get this type of result, we programmatically put an event as of Form Closed event.

And in the event, we assign the value to null.

Sometimes, we have to open the same window as multiple. For this, we remove the inline event as the code given below.

Then, we need to mention the MDI parent. Here, the MDI parent is the Main window. So, we put the code like below.

As mentioned above, let us create forms wanted in this project. The various types of form and their uses have been mentioned below.

Storing data in Properties.Settings.Default

Storing single data in Properties.Settings.Default is a very good idea as we can store data permanently and we can call with a simple code like a variable, we can open the Properties window as below.

Project -> Application Properties.

First, give an appropriate name and variable type (like string, intiger and bool). Then, you can give the initial value.

In our accounting project, we want to create some property item. In the table given below, I have mentioned the name of items with variable type and usage of items.
