I created so many listviews in my project, that im too lazy to add to each listview a resize event with percentages. Is there any other trick, who just scales the columns so as they are?
View 3 RepliesI'm making an WPF-application that has a databound ListView. When loading the application, the width of the ListViewColumns will auto-resize, but when adding or changing an item it doesn't auto-resize. I've tried refreshing the listview, setting the width of the column to auto, -1 or -2 in both xaml and VB-code and I've tries changing the itemssource to nothing before refilling it with items.
This is the xaml code:
<ListView x:Name="lsvPersons" Margin="5,5,5,35" ItemsSource="{Binding Persons}">
<ListView.View><GridView>
<GridViewColumn DisplayMemberBinding="{Binding Name}" Header="Name"/>
<GridViewColumn DisplayMemberBinding="{Binding Gender}" Header="Gender"/>
<GridViewColumn DisplayMemberBinding="{Binding Age}" Header="Age"/>
[Code] .....
After pressing the button, a window will open to add a person. After the window is closed, the item is added to the listview with following code, which refreshes the items in the listview:
lsvPersons.ItemsSource = Person.getPersons()
So, what do I need to do to auto-resize the columns of the listview when an item is added or edited?
I'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.
How can I resize the height of the listview when the user maximizes the form. I used custom controls and it does not work properly with the anchor property. Do any of you had an alternative code that acts just like the anchor property? I will also place buttons below the listview and I would want them to to automatically always stay below the listview.
View 3 RepliesI am converting my company's VB6 program over to VB.net and I have hit another stupid little roadblock.
The old program had a ListView docked to the left side of the application screen. The user could place the cursor over the right portion of the ListView, the cursor would turn into the SizeWE arrows, then they could drag it, which would resize the ListView.
I am trying to recreate this. As far as I can tell there is no Property called "Resizable," or at least nothing is popping out to me. I do not believe that it is being done in the code.
Is there a property I am missing? If not, is there an easy way to do this within the code? (ie. is there a event that would make my life easier)
I am using Visual Studio 2008.
Edit: I see how how it was done in the previous program (you always seem to find it once you ask the question, don't you?). The old program had a invisible picture that was only a few pixels wide that when hovered over would change the cursor to SizeWE. You could then drag that invisible picture and that would hit an event that would then change the size of the ListView. This seems rather convoluted. My question still stands: Is there a better way to handle this dragging and resizing?
I have set up a Textbox Resize event, but when I execute the form, it doesn't allow me to change the textbox size. I'm not sure what code to show; this is a VB.Net book exercise that I'm running in VB 2005. [code] I have tried setting the Border to something beside 'Fixed'. All resize references I have found refer to Forms or tables. Is there a property that allows users to resize a textbox?

Is it possible to have the columns in a listview resize when the listview resizes for the form. Im using VB 2008 express edt.
View 1 RepliesI got a very simple question regarding resizing listview columns. I have a form with a listview anchored to it (top, bottom, left, right). The form is resizable and the user will be able to resize the listview columns manually. However, I need the listview to resize its columns automatically when the form is resized (especially when its maximized).
But, I don't want all the columns to resize, only the ones I choose. For example, the listview will have 6 columns in total (0-5). When the user resizes or maximizes the window, I need only columns 2 and 4 (or columns 3 and 5 or columns 1 and 5) to resize. Now, I have come up with two pieces of code as listed below.
Code Part A: The following code only resizes one column. When the form is maximized, only the column ID provided will resize and fill the rest of the control. It works perfectly but I need to be able to resize multiple columns (as explained above):
Public Sub lvResizeSingleCol(ByVal resizeColumn As Integer, ByVal listViewName As ListView)
Dim w As Integer = 0
For column As Integer = 0 To listViewName.Columns.Count - 1
If column <> resizeColumn Then
w += listViewName.Columns(column).Width
[Code] .....
Just want to ask how to restrict the column resizing if the current width of column is 0.
View 2 RepliesWhat's the difference between the SizeChanged event and the Resize event?
View 4 RepliesFollowing on from my post yesterday (how to anchor buttons/controls to various sides of the current form when the form is resized) I have run into another problem. I am setting the width of my datagrid to be 80% of the form width on a 'form resize' event with 10% of the width at either side so it remains centred in whatever size window is available. This works fine. (mydatagrid.width = me.width/5*4)
I then decided to dynamically set the width of the 2 columns in the datagrid each to 50% of the width of the datagrid. Again, this sub is called in the 'form resize' event. This fails because the datagrid hasn't loaded the data from my sql database when the first 'resize' event is triggered. I did a bit of testing (by placing a simple msgbox statement into the resize event and the load event) and it seems the 'resize' event is triggered three times before the form's load event.
how do I stop the resize event triggering when the form loads (or at least make the load event trigger first).
I've tired to use KeyPress event while in focus of my program's window in VB.Net, but it doesn't work.
For example I wanted to press the number "2" anywhere while in focus of the application and as effect the pixels of the window will change from 200,200 to 600,600 (hortizontal and vertical)

using VS 2010, writting small app which utilises wmp.dll (ver: 12.0.7601.17514 (size: 13.9 MB (14,633,472 bytes)).All works fine except on the openstatechange event the player object resizes every time to approx 250x250. Its driving me MAD!. I have even entered overiding height and width values which it rudely ignores...its a bad bad COM object.I have definately captured the event point where it resizes itself to the exit of the openstatechange event.
View 2 RepliesI have added three columns to the ListView control,
listView1.Columns.Add("id", listView1.Width / 3); listView1.Columns.Add("Name", listView1.Width / 3); listView1.Columns.Add("Address", listView1.Width / 3);
Assume the ListView1.Width is "30", then each column should be in event width of 10. Furthermore thereshould only be three columns becuase i have added only three columns. However, when i resize teh form, the listview controls shows an additional column.
How this was added? How do i fix this, so that when i add 3 columns it will have only three columns even when resized the form or not
how do i resize an object(listview datagridview) if the window is maximized? and how to properly place the buttons when maximized?
View 2 RepliesIn my application I have more then one form/dialogs, of course. My start up (main) form is called "StartForm" and when I want to access to some other dialogs, I open up dialog and I put StartForm on ".Enabled = False" so that user can't access to that form even if he click somewhere on it (StartForm is maximized to full screen and dialogs are small so StartForm can be seen in background when you open dialog). Ok, this works fine until I click on my application "link" in task bar...then, only my StartForm is visible and it's ".Enabled = False" so I can't do anything...I must kill process in task manager. Same thing happens when I open some other application and then come back to my application.
View 6 RepliesI have placed an tabcontrol with two tabs. the first tab contains an textbox (textbox1) and the second tab contains another textbox (textbox2).
View 3 RepliesSo I am playing around with the resize event. My form is 500 wide, my button.left is at 100. If I use:
Dim int As Double
int = button1.Left / Me.Width ' this = 0.2
'resize event
'Button1.Left = (int * Me.Width)
TextBox1.Text = (int * Me.Width).ToString
The number in the texbox is correct - proportion wise, but it won't set the button1.Left to this number. I'm sure this is because int is a Double where .Left is an integer?
I want to resize the form size on button click event.

I simply want to have a list of all graphics saved in specified folder displayed as miniatures - this suppose to be a sort of an image browser - it does not have to be done using ListView, so I'm open to any suggestions.
Back in the VB6 days, I could count on frmWhatever_Resize() to be fired when a form is loaded. That doesn't still seem to be the case. Since my resize event is filled with all the code I want that adjusts the size and placement of things, I decided to just call it from the end of the form's load event. That has no affect. I'm guessing that the form isn't actually shown until form_load is finished?
is there some other event that is fired when a form is shown, so I can call my resize code there?

Does anyone know if it is possible to resize an imagelist/listview image without repopulating the image list? I am using scroll bar to change the image size from 25 point to 256 point. When I leave the scroll bar the imagelist repopulates from the files list. This can be very slow when working with high resolution pictures. I don't want to limit the image size to 2 sizes by using large and small imagelist.

I would like for a user to upload an image to a file in my web application. However, before being saved I want to resize the image to a specified size. I have found code on the Internet to do what I want but I am having trouble adapting to meet my needs. Here is the part I am having trouble with:
' Resize Image Before Uploading to DataBase
Dim imageToBeResized As System.Drawing.Image = System.Drawing.Image.FromStream(FileUpload1.PostedFile.InputStream)
[Code]....
Rather than upload to a database I want to save the image to a folder in my web application. The problem I have encountered is that VB won't let me save a byte() to a folder. Not sure what I can safely change to adapt for my purposes. Why does it need to be changed to a byte() in the first place?
i need the code in vb.net for auto-resize of forms. for example i execute my project in a 14" monitor, the size of the form would be the same as the size of my monitor. now what i want to happen is if i execute my project on my other PC that has different resolution, the form would have the same size of it.
