how to make the preview scroll (smoothly) with the mousewheel?
Private Sub print_preview_MouseWheel(sender As Object, e As System.Windows.Forms.MouseEventArgs) Handles print_preview.MouseWheel
If e.Delta............???
End Sub
I have a usercontrol I created. I added a panel and a vertical scrollbar to the right of it. I'd like to be able to scroll it with the mousewheel. The problem is there doesn't seem to be any events that fire on mousewheel. If I take the panel off then the usercontrol has focus and it will fire on mousewheel in the form. But with the panel on it doesn't seem to fire the mousewheel event of the panel, or the usercontrol within the control or even on the form. The best solution would be to have an event fire in the usercontrol but I'd even accept an event on the form and feed it back into the usercontrol.
I'm using vb.net and vs2005 if it matters.

View 2 RepliesI've dynamically added 20 pictureboxes to a panel and would like to see the panel scroll when I use the mouse wheel. To implement this I have tried to set the autoscroll to true on the panel control. Here is the code.
For i As Integer = 1 To 20:
Dim b As New PictureBox()
b.Image = Nothing
[Code]....
It works for "button" control, but not for the "picturebox" or "label" controls?
How can I implementthe scrolling affect using 'mousewheel'?
Is there anyway to make a picturebox move very smoothly, with my code it is very jerky and ruins the jumping effect i am currently using:

Case Keys.Left

View 16 RepliesI have a button that when the user clicks slides a GroupBox out. I intend to start with the groupbox hidden and with a width of one and when the button is clicked to make the GroupBox visible and increase the width with a for.. to.. next counter.
However when I run the code all that happens when the button is clicked is after a short time the groupbox appears full size. So the program doesn't "refresh" the view of the GroupBox while the for..next statement is looping.
How can I make the GroupBox expand smoothly and visibly?

View 9 RepliesI have a VERY FAST comp/connection. I am looking for better code that runs smoothly. I'd also like if it fails to load something like error.jpg or something, not just staying blank. I don't know where to throw this in the code. I have only loaded 1 PictureBox on the interface, but in the end, I want to load 6-10 on one form at one time.

I'm trying to make a slider, or a custom scroll bar, whatever you want to call it, in VB 2010. But I want it to act as an usual scroll bar. I simply can't make it stay inside my form, it just moves around. I have a photo of my code and my designer down the thread. What should I add? I tried to make it stay inside Panel1.
View 3 RepliesI am loading several command buttons into it (one in each grid box). I have the panel set to autoscroll. When TableLayoutPanel is set to AddColumns, all works well. However, I dont want horizontal scroll, I want vertical. When I set TableLayoutPanel to AddRows, a vertical scrollbar will not appear.

View 11 RepliesI can't get this to work. My program fills all the values into an Excel spreadsheet- no problems there. What I'd like to do is a print preview/print function. I can't seem to get my code right, all I get are blank pages in the print preview box.
Dim oExcel As Object = CreateObject("Excel.Application")
oExcel.Workbooks.Open("C:DailyLogsDailyLog.xlsx")
PrintPreviewDialog1.Document = PrintDocument1
PrintPreviewDialog1.ShowDialog()
oExcel.Sheet1.PrintPreview()
So as I see it, this should open excel, then navigate to the actual excel file. The print preview dialog should come up, which it does, and the excel sheet1 should be previewing, but it's not? I don't have any errors, just a blank print preview. At least thats how I see it, but obviously I'm wrong because it won't work.
I have an application which has multiple files .rtf I open it on a rich text box.
Here is my code for print preview
PrintPreviewDialog1.Document = PrintDocument1
PrintPreviewDialog1.ShowDialog()
I press the button for preview and it shows me the preview. But if I change the content of the rich text box with another file, the print preview shows me empty. How I can send it to a new preview?
Can anyone provide some details on a way to have a thumbnail image of a random file appear in a panel on a form? I'm working on a project that requires this functionality when a user clicks on a item in a checkedlistbox. This way users can auto-preview a file. All code that I found applies to actual image files, so I'm getting "Parameter is not valid" errors when attempting to create a bitmap thumbnail of a text file. Would a printpreview control work?

Because there are times that we need to set the top and bottom margin of the report.
On the left half of my screen I have a datagridview. On the right half I have a document preview pane.As I change rows on the left half, I use the CurrentCellChanged event to open the document associated to that row in the previewer.This works fine, however, the focus is then placed in the preview pane which prevents the user from being able to use the arrow keys to step down a row at a time.To combat this, I made the final event in my CurrentCellChanged routine set the focus back to my datagridview. Unfortunately, even this doesn't always work because of what seems to be a timing issue.If the document to be previewed takes more than a fraction of a second to open, the code to move the focus to the datagridview is executed but after the image completes drawing, the focus is moved back to my previewer.I don't want to use a timer to force a delay and a DoEvents causes me some other issues.Is there some other event I can use to determine when my preview pane is complete and then and only then set the focus back to my datagrid?
