Controls :: Adobe Reader Could Not Open PDF Because It Is Not A Supported File Type
Dec 10, 2012
I am using the code from: [URL] ....
Everything seems to work, expect when I try to open the PDF file Adobe Reader says:
"Adobe reader could not open 'filename.pdf' because it is either not a supported file type or because the file has been damaged (for example, it was sent as an email attachment and wasn't correctly decoded)."
I tried opening it in Adobe Photoshop and was not able to there either.

I read the thread on this topic and tried using "Process.start(mypdf.pdf)" to open the PDF file. I was able to get "Process.Start()" to work perfectly within VS2008 on the built-in server but not IIS; when I am in the development environment it works great, but when I deploy the application and run it it does not work. What happens when I run outside of the development environment, I can export the PDF file to the directory on the IIS server, and the client can also delete the file from the IIS server, BUT, inbetween the export and the delete commands, I have the Process.start command so that the user can open the file and do whatever they need to do; print it, print partially or save it locally ect.
After it exports the file to the server when the exectue "Process.start" occurs, the screen just blinks and there is no error message? I tried many options using Process.StartInfo but no luck. I also tried to to use Process.Start() with a text file (.txt) and had the same result, so it doesn't look like an adobe acrobat problem. I do have acrobat running on the clients as well as the server. I don't think it is a security issue being the exporting and deleting work. Is this the wrong command to use? The web server is IIS7, I am using VS2008 VB.NET and it is a Web application. I need to demo this to the client in 4 days and I need to have this working.

Our ASP.NET application allows the users to review any number of PDF forms. A simple listbox holds filenames and the forms are displayed inside a standard iFrame. The setup is simple and effective: when the user clicks on a filename, that filename is loaded into the iFrame, and shown to the user.
Users are allowed to digitally sign the forms. For appearance purposes, a bitmap of the user' signature is generated and placed in the appropriate location of the PDF form.
The bitmap file format is GIF, and the background is transparent.
We use iTextSharp for form-filling, and we also use iTextSharp to place the bitmap on the forms. Nothing special.
We can readily verify that the signature bitmap is correctly placed on the form, and that the bitmap itself is definitely transparent.
Problem 1:
After placing the bitmap of the user' signature on the form, the form is reloaded and displayed to the user (for verification) and, in most cases, the forms do not display the bitmap. Opening the PDF reveal that the bitmap has been placed and is definitely visible in Adobe Reader (9 and 10 - these are the versions available for testing).
Experimentation and quite a bit of research seems to suggest that the problem lies in caching. One of the possible solution/suggestion is to append a time-stamp or a GUID to the URL, when loading the form after applying the bitmap. In theory, this should prevent Adobe Reader from using a cached copy of the PDF form.
We have tried appending a time-stamp and/or a GUID, without any success: the forms still display without the bitmap. At the risk of repeating myself: the PDF form is correctly signed, and the bitmap is correctly placed. It is just not visible.
This problem seems common to users running the application on intranet web servers (IIS 7). The one application instance running on public web server (IIS 7) does not seem affected by this problem.
Problem 2:
As mentioned, the GIF file generated by our application has a transparent background. In almost all cases, Adobe Reader (9 and 10) seems to understand and respect the transparency of the bitmap.
In one very peculiar case (when the application is running on a Windows 7 64 bit machine with IIS 7), when the bitmap is placed on the form, it becomes opaque (complete loss of transparency).
Again, the problem seems related to Adobe Reader, because the bitmap being applied positively sports a transparent background.

In a VB.Net project I use the Adobe PDF Reader (AxAcriPDFLib) control to display a preview of a selected PDF document whereafter the user can double-click upon the selected listbox item to enjoy a full screen view of the relevant PDF document. see the attached sample in this regard. Is there any way to emulate this in ASP.Net?

I am trying to streamline the look of my site and I was wondering if there was a way to use the onclick of an image to open up a <input type="file.../>? I want the input to be invisible so it doesn't add clutter to the interface. Here is ultimatly the flow I would ideally have... Image click -> Javascript calls input open. User clicks "open" in the dialog, Input calls some Javascript that calls the click event of the inviable "upload" button. Boom. User clicks image, selects a new one, and I have it automatically on my server without the need for two more buttons... Anyone know if these types of events/functions exists and if so what they are called and how to capture them? Or should I stop making this over complicated and use the method that I know works?

I am running MS Vista with the 3.5 Framework. I just loaded VS2008 Express and VB 2008 Express. I was able to create a ClassLibrary project (vbproj) in VB2008. However, when I try and open that in VS2008, I get an error : vbproj cannot be opened because its project type is not supported. The thing is that I cannot create any projects in VS2008 excecpt for Blank Solutions, because there are no templates available to choose from when I attempt a FileNewProject in VS 2008.

I have some code in my vb.net code behind that queries a database, and if there is data, outputs it from the codebehind to a datalist on my asp.net page. In addition to sending the data to the datalist on the page, I need to take the value from "mbillaty" that is returned from the sql query, and have that value be the selected value for a drop down box also on the page. I can get either the datalist to fill, or the selected value for the dropdown box to be selected depending upon which bit of code I place before the other (ARGH), but I can't get them to both work together on the page. What am I doing wrong?

So bit the bullet and installed vs2010 finally. However, when loading an existing vs2008 project, I am getting this error: "The project type is not supported by this installation." the only thing special about this project is that it's a "web application projects" type. what I've tried so far are these steps, but none of these solve my problem:
(1) run "devenv /setup"
(2) regsvr32.exe "%ProgramFiles%Microsoft Visual Studio 10.0Common7IDEProjectAggregator.dll"

I was referring muddasar's one of the article for the validation. Below is my code and i am trying to validate the file upload selected file format on the submit button. I have 4 upload control and fu1 is mandatory field and others are not mandatory fields. Though i need to validate all the four uploads if the files have been selected. My full sample code is below for easy testing,
<asp:FileUpload runat="server" ID="fu1" />
<asp:Label ID="lblMessage1" runat="server"></asp:Label>
<asp:FileUpload runat="server" ID="fu2" />
<asp:Label ID="lblMessage2" runat="server"></asp:Label>
[code]...
I am doing slight mistake on the return to the main function. if i test indvidual function it works fine. whereas if i include the 4 functions in one function with the return statement, it's not validating. goes to to the server.

When the user clicks on "OPEN" button, It should open up that(.txt) file which is on the file server in ReadWrite Mode (like in notepad) without any Access Issues.
Or simply has to be openend as temporary READONLY .Txt File. So that the user can close after viewing it.
