View 3 RepliesReading Page Size Of Existing PDF?
Jan 6, 2011I need to read PDF Page size of an existing PDF. I have both itextsharp and acrobat used in my project. This is what I've tried.
Dim pagesize As Rectangle
Dim reader As PdfReader = New PdfReader(formfile)
pagesize = reader.GetPageSize(1)
If pagesize.Width = "396" Then
Testing = "Y"
Else
Testing = "N"
End If
I get page size as = {Rectangle: 396x309.6 (rot: 0 degrees)}
And Testing comes out = Y
This seemed great at first, until I found that I get those exact same values regardless of how big the pdf is...so now i'm back to square one not knowing where to turn. Interesting thing to note though When I hover my mouse over reader.GetPageSize(1), nothing shows up while debugging, but pagesize does get the value stated above.

View 2 RepliesForm With A Tab Control That Has 18 Pages - Click On A Tab It Opens The Page And Select A Textbox On That Page
Mar 8, 2009I have a form with a Tab Control that has 18 pages. When I click on a tab it opens the page and select a textbox on that page (txtTextbox1. Select() ). This works for the first 8 pages but not for the remaining 10 pages. Although on these pages I can mouse click on the textbox, enter info, save then click my Add button that clears the textboxes and has the code (txtTextbox1. Select() ). The textbox is selected just fine. The code for all my pages is the same except for the tab name and the control names. The tab key will move the selection to the next textbox in order on all pages and the Enter key is coded to do the same. The first 8 pages have a total of 256 labels, buttons, list boxes, textboxes and checkboxes on them.

View 1 RepliesAccess A Page Variable From User Control Placed On That Page From VB?
Dec 27, 2009I want to access a page variable from a user control placed on that page. All the solutions work in C# via casting to the page class. The problem is that this doesn't work in VB. The page class is not selectable from the Intellisense dialog. Manual typing results in the error type not defined. It is strange that C# can do this without a problem. What is the proper solution for this in VB? I had other cases where I needed to access a control on the main page. C# again uses a cast to the page class to access the control. This doesn't work in VB again. So how can I access the page class from a user control in generell?

Scroll An ASP.NET Page Under Control Of The Code-behind Page?
Jun 3, 2009I have an ASP.NET 3.5 page with some AJAX, some Validators and some business-rule validation done in the code-behind page (VB.NET).
The Validators set focus to the 'offending' control when an error is detected.
When a business rule is violated, I used the following code to generate some javascript "on the fly" and execute it to simulate the Winforms "MessageBox.Show" functionality:
Sub DisplayMessages()
Dim lblError As New Label
lblError.Text = "<script language='javascript'>" & Environment.NewLine & "window.alert('"
[Code]....
At the end of the "btnSave.Click" code, if everything went ok, calling that subroutine.
What I get is the page scrolling to the top and then back to where it was when the Save button was clicked.
For various reasons, 'MaintainScrollPositionOnPostback="True"' is in the Page directives at the top of the .aspx code. What I'd really like is to make that FALSE for just a moment so that the page resets at the top - again, only if everything is ok and only for this button (there are other buttons on the page that require the page to keep it's scroll position).

View 2 RepliesFind Properties Of An Existing Control
Sep 15, 2011I'm wanting to dynamically create some controls relative to controls already placed on the forum at design stage, how do I find the locations of the controls that are already placed?For example, I have a label called lblDateTime, its location is (13, 167) and its size is (65, 13).In my code, I want to place a new label below this label.I've tried to set the location and size properties of the new label using the location and size properties of lblDateTime.Size works, no problem, but the location of lblDateTime always returns as 0,0.[code]I want to set lblMessage DateTime. Location to (13, 180), but I'm actually setting it to (0, 13)What confuses me most is that Me.lblDateTime.Size is returning the correct values, so it's not like my code isn't finding the control.

Asp.net - Adding To Page Control Collection From Inside A User Control?
Feb 12, 2011I have an asp.net usercontrol which represents a "popup" dialog. Basically, it's a wrapper for the jQuery UI dialog which can be subclassed to easily make dialogs. As part of this control, I need to inject a div into the page the control is used on, either at the very top or very bottom of the form so that when the popup is instantiated, it's parent is changed to this div. This allows "nested" popups without the child popup being trapped inside the parent popup.
The trouble is, I can't find a safe way to inject this div into the page. A usercontrol doesn't have a preinit event, so I can't do it there, and calling Page.Form.Controls.Add(...) in Init, Load or PreRender causes the standard exception "The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases."
I thought I had found a solution by using. ScriptManager.RegisterClientScriptBlock(Page, Me.GetType, UniqueID + "_Dialog_Div", containerDiv, False) which seemed to work well normally, but recently a coworker tried putting an UpdatePanel inside the dialog and now she's getting the error "The script tag registered for type 'ASP.controls_order_viewzips_ascx' and key 'ctl00$ContentBody$OViewZips_Dialog_Div' has invalid characters outside of the script tags: . Only properly formatted script tags can be registered."
How are you supposed to add controls to the pages control collection from inside a user control?

VS 2010 Adding Properties To An Existing Class / Control
Sep 27, 2011Is there any way to add new properties to a control? For example, I'm using an "OvalShape" from Microsoft's Powerpacks, these are designated as "Cells". I would like to add properties to the class itself (if I had a physical class to edit) for different processes such as "energy level", "family number", "mutation", etc. General variables that are either Boolean, Integers, or etc. If there isn't a way to edit the powerpack class itself, is there a way I can use the ovalshape power pack in my own class and add extra properties to it myself?
