Several years ago I developed a VB.Net 2003 WinForm application using SQL and the DataGrid control. The Datagrid is bound to a SQL dataset in the form load event. Everything work fine.
With the form opened, the user has the ability to size the datagrid control's column width and row height. I want to be able to capture the new row height as sized by the use?
I am working on a personal vb.net project that will allow me to capture a full-sized image of a given web page. I've been working on this for a few of days and have not found a method that is 100% reliable. Here's what i have tried so far...
METHOD #1 - Using WebBrowser Control and CopyFromScreen
Problem: Fails to capture the entire content of the page if part of it is off screen, obscured, or requires scrolling.

I have a user control when a user change its width I also change its height by coding in a certain ratio. I also written some code in resize event of the user cotnrol . Now the problem is how to capture the resize event for height change only as it is running two times first when user change the width and second when height is changed from code .

View 4 RepliesI have a situation where I have several listbox controls on the same asp.net page. They are currently autosized to keep data from truncating. However, I would like to be able to determine the width of the largest listbox and then alter the size of the other listboxes to be the same.
How can I access the size of the listboxes?
I have a request for a util to create a binary file of finite size. For example, the user might want to create a 10KB or 1GB or 400GB file for testing network transfers. I would also like the ability to create multiple files, for example, create 10x 10KB or 5x 1GB or 2x 400GB (so my user would enter qty=5 and size=1GB and have 5x 1GB files in a specific folder).

I'm looking to return a thumbnail image from a full size image stored as varbinary(max) in the database. I'll be using the thumbnails in a gallery-style view, so small size / efficient loading is crucial. I've been using an .ashx to return the full size image into a bound asp.net Image control, with the following code:
Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest
Dim conn As New SqlConnection()
[Code]....
I realize it's probably best to address the re-size at the upload, and stored the smaller image as a discrete column. But in the meantime, is it possible to program the handler to re-size the image on the fly? Ideally, I'd be able to pass an additional query string parameter, something like isResized from the image binding, allowing the same handler to be used for both full size and re-sized images.
I am new to WPF but what i am trying to to do is i have a parentGrid with 3 rows, the first two are a menu strip and a toolbar, the third row is a child grid that is populated with the choices that are selected from the tool bar. the problem is that i want the forms that load in the child grid to not have their height surpass what i have set that row equal to in the parentGrid.[code]

View 11 RepliesI have previously used the arguments of a contentsResized event on a Winforms richtextbox to get the new size of my RTB. I am now developing a WinForms app with a custom WPF RichTextBox. My whole reason for doing this is to use the out-of-the-box spellchecker. I need my RichTextBox to expand and collapse vertically as the text is changed. The elementhost will also have to resize to allow the whole RTB to display on-screen.

So I am hacking together an app which listens to traffic using SharpPcap library, it reconstructs the packets from sessions using the code from TpcRcon.
Listening and reconstructing part work on their own . What I want is on each packet arrival main window gets an event so it can display the packet , and when session is reconstructed display a complete packet (I am interested in HTTP ones) . -That is where it breaks with weird symptoms: for example right now it does not stop on invoking stop listening method - the sharppcap library function hangs there forever waiting on this line of code : m_pcapThreadEvent.WaitOne();//wait for the 'stopped' signal from thread
I also had it not working and crashing in sharppcap function because I had omitted one parameter in form delegate- which makes no sense, because form delegate does not deal with packet capture at all and only reacts on "New Packet" event from my "Listener" class (which is only there to notify main form)
My app starts as module main instancing class "Listener". MainForm has it
registered as friend with event and handles even "New Packet"
Main Form:
Private Sub uiListenStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btListenStart.Click
aLogger.AddMessage("Started Listening")

I have to Panels on a Form. The "upper" Panel is set to Dock = Fill the second "down" Panel is set to Dock = Bottom
Ok. - During the application I add some usercontrols in to the "down" Panel.
Now in one of the usercontrols, I have two group boxes (also set to Fill & Bottom) In the upper groupbox (Dockstyle = Fill) There is a Grid and below the grid, I have two RadioButtons.
On my developer machine, I can see the Grid and the Radiobuttons. On an other machine (other resolution, and other Display), I have the problem that, the RadioButtons are not visible anymore. - The user has to change the height of the "down" Panel by hand, so he can see the RadioButtons.
What I try to do now (and I don't get it working) is: Set the minimum heigt of the "down" Panel so, that both Groupboxes are visible and what is more important: that the commands are all visible.
calculate the height of the grid and the Radiobuttons depending of the solution and used display!?

View 1 RepliesI have a custom control that includes a DataGridView control. I would like to be able to adjust the heights of the rows on the dgv to fill the custom control on the target form whenever the custom control is resized. I am able to adjust the width of the various columns so that the dgv fills the custom control, but I have not been able to adjust the row heights in a similar way. I have tried the following code in the resize event of the custom control
for i = 0 to dgv.columns.count -1
dgv.columns(i).width = newwidth
next i
[Code]....
This doesn't cause an error, but the code does not change the row height. The column width change works fine.
I am able to change the row height by changing the font size at custom control compile time. I have not tried to change the font size at runtime, since this would not achieve what I am trying to accomplish.
I suspect that my problem is that I have not set one or more of the autoresize flags properly, but I have tried all the combinations I can think of.
