IF I open up IE, which I assume the WebBrowser control is based on, I can type the path of the PDF in the address bar, and it views it in the browser, just as it should.
When I do "navigate" to a PDF file, I do notice a short popup (and progress bar) before viewing the PDF in acrobat. It happens so quickly that I can't read it, but it looks like a download progress bar.
I'm having a problem with closing Acrobat. I'm using vb.net to sign a PDF file in running Acrobat. After I'm done I close Acrobat and try to delete the currently signed PDF file, but I get an error message telling me that file is being used by another process. I tried closing and setting to Nothing AcroApp, AcroAVDoc, AcroPDDoc JSO, but still that doesn't work. I tried releasing them with Marshal.ReleaseComObject(...) still no effect.[code]

Tried to look for a solution for this problem everywhere and can't seem to find it?I have found solutions related to sub-classing the document, but this method results in a Null Exception as there is no document.

AddHandler Me.WebBrowser1.Document.ContextMenuShowing, AddressOf WebContextMenuShowing

Some folders, when navigated to,show up in the webbrowser control with the followingcolumn headings:

I am writing a few web based apps which will require a webbrowser extension. I have already used the IE webbrowser control that uses the trident web rendering engine. I believe this is MSHTML.DLL? Anyway, some of the users of my programs have complained of a few things. Particularily,
1. It seems to be a slow browser, at least compared to other rendering engines out there (webkit and gecko are 2 known ones).
2. On the developer side, it seems to be low in features. The features are sufficient in most cases, but there are some "special" things that I need.
3. It has VERY low HTML (and especially HTML5) compliance.
My question is, how much work would it take to use a different engine (such as webkit .net, which I HAVE heard of) and be able to distribute it easily. Or, if you guys feel ambitious, we could try writing a brand new engine ourselves. I know how big of a job it is, and frankly, I have no clue where to begin. I would just like your thoughts and opinions on the matter.
i have created an app to load an access database into a datagridview, which contains web urls.

Ive tried to edit option on the webbrowser control, example javascript enable/disable. but found out that it uses IE's option and cannot be changed.So my question is: Is there a way to do a "webbrowser" without using the WEbbrowser control that is based on internetexplorer? If it is, can i change option example flash and so on?

View 2 RepliesI have a requirement for a new application development where I must present some information to the user for selection via drag and drop. VB offers the TreeView control which would work nice, however the user does not like the Treeview control's presentation. The user wants a control that work similar to the Mac's Finder control while in column view.
Apple's Mac Finder Control works similar to window's treeview. Finder has a nifty view capability that my users would like in some new development that is being done. The finder supports a "column" view. Similar to the treeview, it starts out in a root list. The difference being, when a user makes a selection and clicks on a node, the node doesn't expand, the sub nodes appear on the pane to the right of the list. Clicking on a sub node, will cause the pane to split again and the items within that sub node appear
to the right again.
This will happen again and again with the left pane getting narrower as the user drives deeper into the sub nodes. That is what I am trying to replicate. Obviously, once the user reaches the base list of items, we have to support drag and drop capability. Does anyone know of a control for VB.NET that work similar to the Mac's Finder control?
I'm writing an app that prints of batches of documents to clients for posting. The printer uses OMR to collate and fold the documents into envelopes automatically.The document inputs will either be Word or Adobe Acrobat. I have routines to print off each document type while adding OMR on the fly.
The issue I have is that when the routine for PDF is run, the Adobe file is not closing properly. So when the next clients batch is being printed, there is an error saying that the document is locked by another user or process.I'm using the Acrobat 7 reference library and have Acrobat 7 installed on my machine (full blown product, not reader,) I'm closing the PDDocument, the AVDocument and the application in the code and I've even wrote a routine to kill the process to no avail.

View 8 RepliesI've written an interface with a 3rd party web service in VB.NET. The final step in that interface involves the 3rd party delivering to us (as a stream) a PDF document. After streaming is complete I save a copy of the PDF on our servers, so that our users can view the PDF by clicking on a link in our system. The PDF opens fine in Acrobat X, but when I try to open it programatically I an error saying that "the file is damaged and could not be repaired". I can also open the file in IE just fine, with no issues, and the same code that displays this PDF works just fine on lots of other existing PDFs that predate the 3rd party interface.
I have emptied out temporary internet files as suggested in some posts I saw online. I also opened the PDF in Notepad++ and the %PDF tag is first, and the %%EOF tag is last, so there's certainly no corruption visible in the document source that I can see. Below is the (very standard) code we use to open PDFs into a separate browser instance on our site:
PDFFile = System.AppDomain.CurrentDomain.BaseDirectory & Request.QueryString("LetterPath") & Request.QueryString("Letter")
Response.Clear()
Response.ClearHeaders()
Response.BufferOutput = True

I'm currently working on my personal html editor. i have it where i can preview the page in a webbrowser. on maximized screen i can see the entire page as is. is it possible to keep the webbapage viewed, as viewed maximizied, in a resized browser with this size: 201, 106.
i know i won't be able to read much of the text, i just want to see the page preview, image location, etc. just a browser with view zoom properties.
I'm currently having an issue with VB.Net and Adobe Acrobat. The issue comes from exiting Acrobat but the Windows Taskbar still states that there is an Acrobat.exe process open. I have tried using Marshal.ReleaseComObject(), but it still hangs there. I do not want to have to rely on the "End Process" option on the Task bar in order to remove it.
Below is a snippet of the code that I am try to using:
Try
'Tries To Close Acrobat Application
acrobatApp.Exit()
System.Runtime.InteropServices.Marshal.ReleaseComObject(javaScriptObj)
[Code] .....
Although I am not sure if this could be a problem - I run a javascript saveAs script on the Acrobat side in order to make a copy of the file. This also could be a reason why it is hanging, but I ruled it out based on basic knowledge of saving files and exiting from other Acrobat/Microsoft Programs. Acrobat only closes when my application ends. (Currently) I am trying to make it consider the case if a user manually closes the Acrobat application.
I am creating a project with VB2008 Express Edition. The end result will be a CD containing tech manuals in pdf format which will be accessed via various buttons on a form. I am going to include Acrobat Reader Redisributable on the CD which the user can install by pressing a button on the form if required. What I want to do is this:- When the user inserts the CD into the PC, the form will load.When the form loads, I want to search the users PC to determine if Acrobat Reader is installed.If the Acrobat Reader program is not found on the system, then display a MessageBox to inform the user to install the reader from the CD.Would this involve searching the users registry? I would need to insert in my Form1_Load sectionTarget systems would be Windows XP/ Vista with programs on the C: drive as default.

Any way to do it without adding the complication of requiring ActiveX?
