When picturebox1 sets picturebox2 as the parent container, the position of picture1 becomes the posi

After the parent container is set, the position of the child controls is calculated according to the coordinate system of the parent container, right? That's why the location is different from what you might expect.

Does moving in a straight line mean that the control runs directly to the target position or does it have the process of making the control move?

If it's the former, directly.

90-40);Past.

If the offset method doesn't return a value (I didn't turn on vs, I forgot what the definition of this method is) use a temporary struct variable to do the intermediate processing:

point p = ;

p;If it's the latter (with time changes). Then you need a timer to do that. Use a formtimer (definition seems to be in.

The properties to be set are: internal (time interval, generally set to 50, that is, 20 times per second, which is equal to 20 frames).

enabled=true, enable timer

tick+= handles events.

In the processing time, the above direct jump method is used to change the position of the control frame by frame, such as adding 1 to the XY coordinate every time. You can design the specific changes according to your needs.

If you follow the linear motion you said, you can calculate the position of the widget in the tick event by adding the current coordinates to: (target coordinates - original coordinates) the number of frames that moved before reaching the target.

Switch to form1 of the form application, press Ctrl+Alt+X to open the toolbox, enter pic in the search box, find the picturebox control and drag two of them to the form.

Also double-click picturebox1 to generate picturebox1 click event handling, otherwise an error will occur.

Do you have a picturebox control on your interface?

Solution:

2.General method: set the transparent color attribute of the form to your png transparent color, = ;

Make sure that all color changes on the form are transparent.

3.You try, maybe you can: the opaque one is set to the backgroundimage of the picturebox, and the transparent one is set to his image

Use the gid to reconstruct a new ** to achieve the effect of overlay.

If this doesn't work, set backgroungimage to the background ** and image to png

If you just want to select it, select it above the properties box on the right side of the software window.

1.Best Practice: Use.

gid reconstructs a new ** to achieve the effect of overlay, and the disadvantage is that it can only be displayed with a picturebox.

2.General method: set the transparent color attribute of the form to your png transparent color, = ;

Make sure that all color changes on the form are transparent.

3.You try, maybe you can: the opaque one is set to the backgroundimage of the picturebox, and the transparent one is set to his.

Needs to be implemented in **:

This is a bit cumbersome and can be done with quadratic linear interpolation, but it's best to do it with an external program such as PS or ACDSEE!

What you mean is that the child window passes a value to the parent window, for example, for example, your form1 must have an event that makes from2 show up.

private void button1_click(object sender, eventargs e)

You create a global variable in from2, such as public string urll;

Then write a property to from2, I guess you haven't learned it yet, it's similar to building a function, but there are no () parentheses, let's understand it this way;

public string geturl

The OK button in your from2 assigns a value to urll, which is the value you want to pass as follows.

private void button1_click(object sender, eventargs e)

Then go back to the ** above, and when you create from2, you have a geturl attribute, and the value is the value you passed. After you click OK in form2, you will go to the place where form1 creates a new form2 object, and you can try it if you don't believe it. See if you can be inspired.

It's easy to pass form1 as a parameter to the new form2.

That is to say: when creating a new form F2, when it is not modified, it is F2=New Form2(), now it is changed to, F2 =New Form2(this).

Define a form1 variable in the form2 class, and you're good to go.

Method 1: Set pictruebox1 in form1 to public

Method 2: Use form1 as a property member of form2 and assign form1 to form2 before the show after creating form2

Determines the click event () for the button

Professional program problems are recommended that you go to the programmer forum to ask faster, and many people on CSDN solve them quickly.

However, only if form1 is not destroyed.

Define a public class, put the attribute of ** in it, and the number in it, the class is static and can be accessed by all forms, one form changes the value, and several changes to the value in it, which can play the effect you said.

Add a dynamic picturebox and call the dynamic picturebox in form1 and form2 respectively
