C pictureBox cannot be added to Form1

string sqlstring = insert into table value;

sqlcommand slqcom = new sqlcommand(sqlstring, database connection object);

int i = ;

sqlcon_;

return i;

The form doesn't seem to have a self-refreshing method, you can only overload the form

Declare a static variable in form2 that holds the file path.

Write in the click event of each picturebox.

Assign a value to the static variable in form2, initialize the instance of the form2 object, and set the path to the picturebox in form2.

private static form2 instance = null;

public static form2 getinstance()return instance;

form2 constructor Bi Bo Li Hand Yu Xiang initialization instance = this;

public void setpicture(image image)

image;

The above generation of dismantling and punching codes are all in form2.

form1 when you click on the picturebox;

form2 defines the whole trace infiltration picturebox variable form1 picbox point pose naridge eggplant cherry strike event in form2The name of the global picbox variable. image=((picturebox)sender).

1.Set the modifiers property of picturebox1 in form2 to public

2.Write ** in the form1 button event.

form2 f2 = new form2();

= true;

There are many ways to implement this:

Here's a kind for you:

1.Define a class (e.g. backcolors) with a static variable (e.g. bcolor).

2.After pressing the button in form1, let = backcolor of the picturebox widget in form1

3.Add a timer to form2 to regularly refresh the backcolor=

Select grades from Class Schedule COU, Student Information Form STU

where and 'Someone's name' and 'Course name'

Is this hard? Isn't it okay to set the relevant properties directly? Why do you find it so hard to do so?

The tag property of the object created with form2 stores the information (path) of the selected **, and form1 obtains the ** information by calling the type, and then assigns the value to the **box

Instancepicturebox1 got the ** in 2.

In form1, button1 clicks

form2 f2 = new form2();

In form2, you add a field.

private image img;

public image img

Button1 click;;

That's it.

It's easy to do with GDI+.

graphics* g;

graphicspath mygraphicspath(fillmodealternate);

int offsetrx=m_ ;

int offsetry=m_ .y ;

rectf myrectangle(offsetrx,offsetry ,m_,m_ .y );

myrectangle);

matrix* mypathmatrix=new matrix();

g-> above are partial **.

Considering that you need to understand Wang and the internal process, so give you ideas.

First, set up a coordinate system, get the value of each pixel, and then replace it according to your rotation method. Usually this is very slow and wastes memory. It depends on the algorithm skills.

I've written a VB to get the RGB value of each pixel in the past, you can refer to it. Then replace the pixel values according to a certain pattern according to your coordinate system.

First define a button in form1, the function of the button is to get the ** path of the picturebox in form1, and pass the obtained path to form2, and set the ** path of the picturebox of form2 in the onload event of form2! Here's the idea.

Is there a function that is a private or protected modifier?

Then you can launch a new instance separately, and you're good to go.
