In many apps I have needed to disable the maximize and resize features of the main window because the textboxes and buttons stay exactly the same without realigning or resizing automatically. How can I change it so that buttons maintain their proportions and that textboxes will stretch when the window is resized?
View 3 RepliesFor the resize I have a form to reduce and expend image code:
Dim source As New Bitmap(Form1.PictureBox1.Image)
Dim target As New Bitmap(Size.Width, Size.Height, PixelFormat.Format32bppRgb)
Using graphics As Graphics = graphics.FromImage(target)
graphics.DrawImage(source, New Size(16, 16))
End Using
As far as I know it resizes but when I save I get the default icon image instead of whats in the picture box?
I have a picturebox that I am importing an image to. I need it to expand but not expand past my buttons at the bottom of the screen. When I import the image it takes up the whole screen and covers up my buttons.
View 9 RepliesI'm trying to resize various datagridview objects at run time, using the following subroutine
Sub GridHeight7(ByVal grd As DataGridView, ByVal highest As Integer)
Dim jr%, w&
With grd
[code]....
It appears that that only the top property is passed to the subroutine, that is, rowcount and the others appear to have a value of zero. Using ByRef makes no difference.
I need to let the end user move and resize objects (like a textbox or button). There are several examples that demonstrate this in VB, but not in VB Express 2008, based upon VB.net.It looks like earlier you needed to access Windows API, but these calls does not work in VB.net. I understand that these call are replaced by "native" .net calls, but I cannot find any that does the job.
A typial example from old VB is:
Private Declare Function GetWindowLong Lib "user32" Alias "GetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long) As Long
This does not work in VB.net.
i have managed to get the form to resize according to the screen resolution but now im struggling to centre the objects on the page?

View 3 RepliesI'm starting work updating an UI for one of my company's applications and I'm running into a sticky issue. The parent control contains several panels, each of which can be turned on or off depending on user input.
The final panel in the user control contains another user control which gets resizes according to a toggle switch. Essentially, it "opens" up more information.
While the child control (ChildControl) is docked to Fill inside the parent control (ParentControl), when I add height to ChildControl I can't get ParentControl's height to get updated as well. Currently I'm handling the ChildControl.Layout event in ParentControl but I can't seem to reach that code. To resize ChildControl, I'm calling Me.Height += 200 in ChildControl.vb.

View 14 RepliesI have a VB.NET (VS08) app that I want to add context sensitive I have added the Helpprovider control and set the helpNamespace to the help file (chm) file.I then went to a control on the page and have been playing with the HelpNavigator properties to have the file open the the correct topic in the TOC, but have not been successful. I can get the file to open to the TOC but not expand and navigate to the topic.
I have tried setting the HelpKeyword to ( my topicid is pending_email_manager):

pending_email_manager
And, setting the HelpNavigator to TableOfContents, Topic and TopicID.
I have now wasted way too many hours on something that should be simple (and was simple in vb6).
I need to create a solution in which I populate some rows with data from a database.In those rows I put usernames and total values (total resulted from products selled in one month by every user)The idea is that I need to make somehow that when I click on one user (event CellContentClick on DGV) to expand the user in the way that I can see all products selled by that user in the selected month.I readed on the internet that I have to use datagridview inside the datagridview.I was thinking maybe I can have some expandable rows inside the datagridview (like in Excel) and when I click on + sign to expand the rows and to populate with selled products.

I have a routine which allows me to expand the size of my DataGridView within a TableLayoutPanel. Effectively it repositions the DGV to the first row and first column of the TableLayoutPanel that it is in using the SetRow and SetColumn methods of the TableLAyoutPanel. Then it sets the column and row span by passing the row and column count properties of the TableLayoutPanel to the SetColumnSpan and SetRowSpan methods. It work fine. There are two buttons on the form, One expands the DGV the other returns it to its original state.
My question is, how would I set this up if I wanted to do this for all the controls in this TableLayoutPanel and/or every control on every other TableLAyoutPanel on my form. I am assuming I have to use a class as I would have to create an abundance of public variables to pass the row/colum and row/column span starting positions to.[code]....
Actually, I'm not looking for the way to expand its width.I have a combobox with a given width.It may occur that one row of the data is partially hidden. I'd like to show the whole line by using tooltip or right-click context menu.What do you think? What's the best approach for this scenario? Anyway, I can't find how to 'catch' the row that I'm currently holding on or passing over by mouse.
View 6 RepliesI have a combo box on a form that is set to certain width. The data the combo varies and can be quite large. Is there a way that the combo box could be expanded to fit the widest data/text when the Combo is selected?It would be quite neat if it pop out of the form when selected! I guess I could create this effect by creating another form that opens when when that object is selected.
View 5 RepliesI know how to make things expand on mouseover, but how do i make it expand slowly? not that it has to take ages, but not instant either. I need to expand a listbox from width 20 to width 400 in an even manner.
Also, i would like to have the backcolor of the listbox to change from white into red for a brief second and then change to beige and stay beige until mouseleave, you know, make it look a little flashy and stuff.
make objects from the ToolBox using code instead of changing existing objects invisible then visible later?

I am trying to make a form expand from one size to another using a slider animation.
The problem is when I run it the form resizes but without the animation. I'm not sure how to use the animation when resizing the form. It works if the form is a set size and then I run the animation.
The form is borderless and starts out with a width of 11 and I want the final width to be 285.
The resize and animation are triggered by clicking on the form.
Here is the code.

Me.Width = mintformmaxwidth
