I just don't get it. Seems that the method Clone(Rectangle, PixelFormat was not found.

View 5 RepliesResolution-based Resizing?
Jun 7, 2010Usually I am a web developer so this is probably a very novice question. I recently made an app in VB2008, but I developed it in a huge reso (1920x1200). The person that will be using it still uses 800x600 reso. Is there any simple way I can resize the entire interface to fit any resolution? I didn't really think about it at all while I was making the program.
View 1 RepliesAny Way Of Automatically Resizing Forms?
May 2, 2011How to make my forms resize automatically. here's the situation. I have my intro screen, which a user may want to maximise. Once this is maximised, the whole program should stay maximised. Again, if the user chooses to restore the window to its default size, the whole program should remain in that default size. However, once the user clicks the button "Press here to start" on the intro screen, the form automatically reverts to its original size if it was maximised. I also need to be able to stretch the contents in the correct ratios to fit the new screen size.

Jan 26, 2011Lets say I want to create an array with 20 elements all set to a default value (let's say, 0)
But later, during runtime, I might want to resize the array. I might make it larger, to support 30 elements. The 10 new elements will have the default value of 0.
Or I might want to make my array smaller, to just 5. So I delete the complete the existence of the last 15 elements of the array.

View 2 RepliesForms - Resizing Controls Accordingly
Feb 12, 2011we all know how to dock or anchor controls so that they resize themselves accordingly when a form is resized. It works fine till we have rows of controls on left and right size of the form. But what if have three columns (Columns as in visual sense. I'm not talking about any column control containing other controls) of controls? For example a form having a bunch of controls in the left side, a bunch in the middle and a bunch in the right. There may be a few more bunches in the middle. Now while resizing the form, I want the controls to resize accordingly as well as change their positions to make space for the previous bunch of controls that are resizing.
I mean, while the user increases the form size horizontally, the controls of the second bunch should resize and at the same time they should move right because the controls of the first bunch are increasing horizontally too. When the user decreases the form size horizontally the same thing should occur in the reverse order. I can manage it somehow using nested split-containers but that's too cumbersome. I would like to know if there's some better way to achieve it, like setting some property etc.?
Forms And Resizing In 2008?
Aug 12, 2009Currently, my application is comprised of:a Main Form On this Form, lies an array of User controls, (pardon my terminology, i believe the more proper VB.Net term is Collection of controls). Within these controls are pictureboxes that have distinct graphics drawn on them. When I run this program, no graphics are drawn in the pictureboxes or it appears the graphics are overwritten. Also, it seems that the Form resizes uncontrollably varying in size on the screen and hits an infinite loop. I use the Form_Resize function for updating the size of the form. What could be causing this problem. What is the Paint method used for?Currently, to draw graphics on the Pictureboxes i am using the graphics object. I have two pictureboxes within the usercontrol for toggling back and forth for a more fluid refresh upon property updates.
From my reading, vb.net does not allow the ability to create an array of controls on a form, so I attempted to create an array of controls dynamically to try and stay as close to my vb6 application as possible because my knowledge is limited. This works, from what i can tell I know that in the Upgrade wizard the VB6.Compatiblity reference was used to try and mimic an array of controls, but I wanted to steer away from that and program strictly using VB.Net commands.
How To Prevent Form Resizing
Apr 26, 2011I want to prevent from resize of form. I set false MaximizeBox and I set FormBorderStyle to FixedSingle. I couldn't change the MaximumSize of form at runtime. If the user double click on the Tiltebar of the form the form resized. I couldn't prevent that
Then I write the following code at size changed event
If FormLoaded Then
Me.MaximizeBox = True
Me.WindowState = FormWindowState.Maximized
Me.StartPosition = FormStartPosition.WindowsDefaultLocation
Me.Size = InitialSize
Me.MaximizeBox = False
End If
MDI Child Forms Resizing
Jan 19, 2011Has anyone ever had or dealt with resizing issues on MDI Child forms? I am working on a VB.Net Windows applciation project I inherited from another devloper. When I took it over the forms had already been designed. There are one MDI Parent Form and two MDI Child Forms. When the application starts up the parent form and one child form open by default. Both the parent form and the child form will maximize, restore, and minimize. Although I have to move the parent form slightly, when it is not maximized I can resize it with the mouse pointer as expected. The child form will not resize and when I move the cursor to the border of the child form I do not even get the mouse pointer. Also, when both the parent and child form are maximized the vertical scrollbar on the child form is no longer displayed.
One potential problem is that there are lots of controls on the child form, which are inside several group boxes. When I comment out the controls, the blank form displays without the vertical scrollbar but will resize with the mouse pointer as expected. When I uncomment the controls the resizing does not work any more. The AutoSize propery on all of the controls is set to True. I tried commenting out the code setting the Autosize property to True on the group boxes only. The result of that is that the resizing still does not work and I lose the vertical scrollbar.I am trying to avoid having to redesign the form completely, however I am running out of alternatives. The project will not pass UAT if the resizing does not work.
Resizing A Form In Code?

If the user selects 2 players id like the second players score card to become visible on the Score Card window (easy enough with the visible property) and i would like the Score Card form itself to resize it self (at run time) to allow the second players score card to fit. How do i make the form resize to fit 2 players at run time?
