Forms And Resizing In 2008?
Aug 12, 2009
Currently, 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.

So, my question is, how do I programmatically resize a Form beyond the boundries of the screen?If I try to simply set the Width property for example, it will only extend the width of the Form to the edge of the screen and not beyond that (even the width that I specified extends the Form beyond the screen's edge).

How 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.

we 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.?

Has 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.

I have a basic windows form. I have one command button of the default size right in the middle of the form. I also set the anchors for the command button to keep it in the center when the window form is resized.The issue is when I maximize the the window form the command button remains in the center, but it has grown in size tremendously (almost taking up the entire form).I want to keep the command button centered when the form is maximized, but I also want to keep it the same size. Is there a property for the command button I am overlooking which will do this?

How do I get my Form1 to resize so that all the (components) buttons and datagridview, etc. stretch and grow with the screen, but stay in their relative positions? I've tried adding Panels around the elements and docking and anchoring, but, so far no success. Elements scatter and don't hold their position, etc. Is there an easy way to do this?

I am creating a form in vb.net and i want its size to change the form as soon as the user inputs the desired number of items. In my form I have two combo boxes: one for number of items and the second is for the choices, then when the user choose 5 items 5 text boxes will appear and if the choice is 25 then 25 text boxes will appear. Is there any way that I can change the form based on the input and number of text boxes?

I have a form that sits on the user's desktop. It's only purpose is to display specific information about the computer. The layout is basically setup like this:
[Code]...
I want to be able to give the user the option to display whatever data they choose. In doing so, I'd like the form to resize itself based on the how many labels are in the form and for the labels to align vertically.
Can anyone point me in the right direction? For the form, I was thinking I could get the location of the last label and offset it's size by the location, or something similar.

developed my app on a Vista laptop and deployed it on an XP desktop. When deployed the Form and even some controls are resized so text and portions of controls are not visible.Next I moved the project files and VB to the XP desktop and published the application on that machine. Same result, in fact the sizes were changed within the properties of the forms and controls within the project files

I'm trying to prevent resizing of the "headers" (columns) in my ListView control. I currently have the following:
vb
Private Sub savedColors_ColumnWidthChanging(ByVal sender As System.Object, ByVal e As System.Windows.Forms.ColumnWidthChangingEventArgs) Handles
[Code].....
This results in a System.StackOverflowException. How can I fix this or is there a more appropriate way to prevent resizing of the columns?

I'm trying to set up a system to resize multiple objects on a form (40+) when the form resizes. I've got it working but it's rather slow, when I resize the form it stutters a lot from looping through the objects to resize them. Is there a better way to do this that would not cause the stuttering effect?

I have a picture box on a form that changes size as needed. Both by resizing the form and by code.How can I resize the form automatically if I resize the picturebox in code. The client area of the picture box should not be clipped.Right now the picture box is set to dock fill, but if the code resizes it, the form does not follow it. Is there a binding somewhere I can use?

i have a problem with trying to get 2 forms to close at different times using a timer on each of the 2 forms.
This is my form layout:
Quote:
frmMain
Frm1
Frm2
Frm1 and Frm2 are identical to each other. FrmMain has 2 buttons on it. One button to call Frm1 and the other to call Frm2.Frm1 and Frm2 each has a timer. It counts down to 0 and then does a .close(). However, if i pause between clicking the second button they both seem to always disappears at the same time.I would do something like this...
Click on the first button (showing the Frm1 form)
wait about 10 secs...Click on the second button (showing the Frm2 form)they both are shown on screen...hen they both disappear at the same time.... which shouldn't happen since i clicked the Frm2 box 10 seconds AFTER Frm1... So Frm1 should hide before Frm2 does...but it does not.

Is there a way to be able to resize a form from somewhere other then the lower left? Normal the form is 1080x1024 but i have a few people with laptops that are smaller and there are scroll bars, but it opens too big for the screen and the resizing can only be done in the lower right. Is there a way to change that without having to adjust my form layout?

Usually 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.

I have a listbox and a panel. In my forms resize event, my listbox is always form1.width * 0.5 and then the panel is also, but it doesnt work very well. They overlap at a certain point but in theory, they never should. Is there something wrong with my logic?

Lets 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.

My full screen sized Form is locked in size when I reduce it in size by clicking on the "restore down" [ie] not to the minimized size. I mean "locked in size" by I cannot for instance "grab" it on a corner and to increase or decrease its size. I suspect the control is in the properties window but I cannot find it.
