Resizing forms

Mar 13th, 2009

hi all,
N good morning!

I am developing an application in vb. I had developed my application on my PC in 1024*768 screen resolution. When i rum my application in the same screen resolution then it runs properly but when i run my application on 800 * 600 sreen resolution then my some controls on form are not visible to user.

I try to solve this problem by using picture box and putting all controls on picture box but then also some controls are not visible to me.

Can anybody help me in solving this problem as soon as possible?

Thanks in advance.

Regards

you need to resize and rearrange the controls based on system resolution. You need to use X and Y coordinates of the screen.

Share your Knowledge.

This code is just for one of the aspects: the left position. But the principle is the same for the top position. And if you want, the height and the width.

Use ratios to find the value that you need. In each situation, you need 4 values. One value has to be calculated.

On loading you can extract the original height and width of your form. And on a resize event, you can extract the new size and width of your form.

The values that you might want to change are the left, the top, the width, and height positions of your controls. You don't need a picture box to manage your controls. The new top, left, height, and width positions can be calculated with ratios based on its previous position.

Here's one formula for finding the new left position using ratios:
CurrentLeft / CurrentWidth = NewLeft/NewWidth

Use the same principle for calculating a new top position, height, etc.

Hi,

Place the Image Control on the Form, Make its property :
Strech = True
and in Form's Re-Size Event Write this Code:

1.
Image1.Width = Me.Width
2.
Image1.Height = Me.Height - 300

I like sword. Attack or Defense.
