I don't use local VS2015 LZ said this problem, this is my local code

 
//Form1. Cs:

Fa. MdiParent=this; 
Fa. The Show ();

Enclosing SuspendLayout ();

Enclosing IsMdiContainer=true; 
This. Name="Form1"; 
This. The Text="Form1"; 
Enclosing the Load +=new System. EventHandler (enclosing the Form1_Load);

//FormA. Cs: 
Private void button1_Click (object sender, EventArgs e)

FormB fb=new FormB (); 
Fb. MdiParent=MdiParent; 
Fb. The Show (); 
} 

CodePudding user response:

Added to the second method is the system automatically generated, I just put the main form of IsMdiContainer attribute set to true

CodePudding user response:

Your way is much document form on the second floor

CodePudding user response:

Your code has a problem, child form the default will only shut down, according to the main form closed won't appear what you said at the same time to minimize the situation

Thank you, is my own program error, can ask you A question, do you understand the multiple knapsack problem, I have N items, the weight of each item and the value is 1, the biggest desirable quantity each item is an array A [N], each item can not take, I want to output all the feasible solutions (including each item how much), are looking forward to your reply, thank you thank you, all give you, I'll add

CodePudding user response:

Arguably not, whether you use formB. Show (this), get rid of this
