HTML 5 Compatible File Browser Control

Has anyone seen a a plugin or sample demonstrating a html 5 compliant file browser control for APEX 4.x? I know of a pay to use plugin but my office is leery about buying a 3rd party plugin. I know there are jquery plugins available, but was looking to see if anyone had already done the heavy lifting.
Mainly we are looking to implement this to limit what types of files are uploaded by users, so instead of telling them AFTER they upload the file, we limit what type files they can upload BEFORE they have a chance to upload incorrect file types..
Thank you,

Found this old thread with what will suffice.. Adding a onchange event call to the documented javascript function will suffice to what they need: How to set "Files of type" when using a "File Browse" item.

for example.This is done to produce a unique file identifier in the <tt>apex_application_files</tt> view, and is the session state value of the file browse control that uploaded the file. The actual filename is available in the <tt>filename</tt> column.
How do i save the full path does anyone know?Generally, you can't.
For security/privacy reasons recent versions of browsers by default do not send local file path information from File Browse items to the server, nor expose the file path in the control's JavaScript methods. Firefox, Safari and Chrome only provide the filename. IE6 & IE7 still yield the path in Windows format. IE8/9 and Opera have adopted an irritating approach of replacing the path with a wholly imaginary "C:\fakepath\".
Changes to IE's security config setting “Include local directory path when uploading files” enables the path to be exposed in IE8/9, but unless you're working in an intranet environment where: IE is the only browser used; it's possible to make remote changes to this setting on every desktop; and this won't break/expose anything else, then you'd be strongly advised to rethink this requirement.

File browse control function panel

How to create a file browse control on function panel? Data type for file path is char*. By dropping a input it does not provide with the browse button.
Thanks

This help topic describes how to add the ... button on the function panel and associate a callback to it.
You could start from the example from samples\functionpanels\Customization\SelectColor.cws and write a function like this:
int DLLEXPORT CVICALLBACK SlectPath (FPCustomInfo *info)
   char path[MAX_PATHNAME_LEN];
   int parameter;
   FPCustom_GetSelectedParameter (info, &parameter);
    FileSelectPopupEx ("", "*.*", "", "select file", VAL_OK_BUTTON, 0, 0, path);
   /* additional processing to convert path into a string literal - enclose in quotes and
   replace special characters like '\' into escape sequences */
   FPCustom_SetParamValue (info, parameter, path);
   return 0;

File Browse field in other languages

Hi all
I'm using Apex 4.0.2 with theme Scarlet(21) and I'm writing from Italy (this could be important for someone to understand my Windows 7 settings).
When I put a File Browse control on a form, at runtime, I see the form with all the fields and label in English as I wrote them but my control is in Italian.
Is there a possibility to "customize" the control to obtain it in English independently from the local settings ?
Thanks a lot,
Massimo

Massimo,
I'm sorry.. I had different priorities today.

Dynamic action on File browse change event

Hi Experts,
apex version 4.1
This is what i'm trying to do..
i have a file browse control and a text field. when user selects a file, selected fiel's name (without file type extension) should be set to text field.
I tried adding a dynamic action to file browse control's change event and within pl/sql Set Value logic i queried the wwv_flow_files and tried to return the file name it didn't work. i got no data found error. i assumed file is being inserted into wwv_flow_files when a page submission happens.
In my second approach within the SetValue pl/sql logic i got the file browser control's (by directly accessing field, not by querying wwv_flow_files)value and did some string manipulation and tried to return only the file name. yet i got the same no data found error.
Any idea how can i implement this ?
Thanks in advance.

Hi,
I think PL/SQL approach will not work before you submit data to database.
Have you think use $v function to get value from file browser?

Visual Studio 2013. Viewing a PDF file via the Web Browser control in Windows 8.1

I am writing a Windows Forms application in which I need to view PDF files via the Web Browser control. When the control is given the Navigate() command, Windows takes over and asks which program I want to open the file with. All was fine with VS 2010 and
XP. I have un-installed "PDF Complete", which was the default PDF viewer, but I now get asked for an alternative.
Thanks in advance.
Mike Saunders

Hi Mike,
It seems that we could use Internet Explorer to open a local .PDF file if it has the Adobe Reader. I doubt that the web control would be related to it. Like the MVP's suggset in the following thread, maybe it would be related
to certain plug-in tools in your side like the adober reader.

How to force the File Path Control Browser button to the RT Target instead of the host machine?

I am building an application on a RT PXI system, and for one of the functions I would like the user to be able to use the browser button of the File Path Control to choose a directory on the PXI. However the browser button seems to only want open a file on the host PC, even though the application is fully deployed on the target. Note that I am controlling the PXI from a host PC.
If anyone has any suggestions that would be great. Thanks.

Hi,
Unfortunately, there is not a VI to do this. Are you browsing to these files from your host VI? In order to access the files on your PXI RT target, you'll need to FTP in and browse to them that way. You could programmatically do this, but there is not a simple VI to do so.

File path control - browse button colour/color

I can't change the colour of the browse button on a file path control. I'm using LV 8.5, but I think I have the same problem on 7.1
Is the only way to change the colour to customise the control? Every other part of it seems to take colours from the tools palette.
Thanks for any pearls of wisdom.
Jon.

I am able to change the path browse button color in 8.51 are you trying to change the button color or the color of the folder on the button. To change the buttoin color use the paint tool and make sure you hit the space bar so you are painting the left color (Background color I cant remember which is which). This probably doesnt work on system buttons.

File path control: invoke file browser activation

Hi there,
on the front panel of a vi I want a file path control to open automatically the file browser window when the user clicks into the path control. Is there any way to do that programmatically after the mouse down event has been fired? I couldn't find a suitable method so far.
Thanks for any hint,
Peter
Solved!
Go to Solution.

I should point out that the mechanism you (I am referring to the OP) are proposing is counter-intuitive. Web browsers have started to do this, but they do it claiming security issues. Frankly, I think the security concern is small compared to the annoying change in normal behavior, but that's my just my opinion - I can't change the way Firefox or IE works.
Do you not have the Browse button visible for the control? Clicking this displays a file browser. This is normal and expected behavior.

How to get full path in file browse item

Hi
I have a file item. When I submit the form and store and value in db, then the file path is stored as numbers and appended to the file name. I undestand that this is because of some wwv flow files index or something . How to get the file path? Anybody...

File Browse is emptied after failed validation

Why does the file browse text box get emptied after a failed validation? Is there any way to prevent this?
To further explain, create a form on a page with two page items, a text box and a file browse item, then put a not null validation on the text box. When you submit the page with a null text box, but with a file selected for the browse button, then validation catches and throws the error message back to the user when the page refreshes. However, the file browse text box is emptied, and the user has to reselect the file before resubmitting the page.
Is this a bug, or just the way it is supposed to work? Any way around it?
Thanks,
Kris

Hello,
>> Is this a bug, or just the way it is supposed to work?
This is not a bug. Actually, it has nothing to do with APEX. The behavior of the file browse item is controlled by the HTML standard, which clears the field for security reasons.
If you pay close attention to Denes example, you’ll see that even when the validation error page is displayed, the file browse item itself is being cleared. The JavaScript generated file path is the one that retain its value. I don’t have access to Denes code, but I’m assuming that in his uploading procedure he’s using the JavaScript generated path.
>> Any way around it?
Where the file browse item is concern, no workaround.
In your specific case, where the validation you need is “not null”, you can create a JavaScript validation, and fire it before submitting the page (as part of the submit button). That way, the browser will not clear the file browse item, because the page will not be submitted without proper values in your items.

Arie.

How I make the Web Browser Control to display a PDF in Windows 8

I have an application that run ok in previous version of windows, Where I can load a PDF file and the web browser control automatically use the Reader OCX of Adobe,, After Install windows 8 and download the reader for windows 8 still get and (X) where the document should be displayed. I use the following command in my program to force the windows 8 to use the same web browser (10) in my web browser control.
WebBrowser1.Navigate(DocumentName,"",Nothing,"User-Agent:Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; WOW64; Trident/6.0)")
But still get an (X). IF I use the URL that is in the property of the (X) and paste in my regular IE10, it open the PDF file.

Adobe Reader Touch is a Windows Store app and does not install a browser add-on/plug-in for "in-browser" PDF viewing.
You can either
Install Adobe Reader XI (desktop app) which installs browser plug-ins for Microsoft IE and Mozilla Firefox
Use Google Chrome, which has a built-in PDF viewer (enabled by default)

How to set "Files of type" when using a "File Browse" item.

Apex 4.0.2
Internet Explorer 7 +
I have a "File Browse" item on a page and need to limit the types of files display to just "text (.txt)" files. How can this be done? Currently, the "Files of type" list shows "All File (*.*)", "Pictures (*.gif,*.png)", and HTML (*.htm,*.html)". In the best case, I would like to not have the "Files of type" list and have the user just limited to text files. However, adding Text files (*.txt)" to the "Files of type" list is ok.
thanks,
William

Thought i'd do a bit of research after seeing Scotts wonderful ideas.
So it turns out, IE made the file item read only from version 8, for security reasons. Read more: http://blogs.msdn.com/b/ie/archive/2008/07/02/ie8-security-part-v-comprehensive-protection.aspx
File Upload Control
Historically, the HTML File Upload Control (<input type=file>) has been the source of a significant number of information disclosure vulnerabilities. To resolve these issues, two changes were made to the behavior of the control.
To block attacks that rely on “stealing” keystrokes to surreptitiously trick the user into typing a local file path into the control, the File Path edit box is now read-only. The user must explicitly select a file for upload using the File Browse dialog.
Additionally, the “Include local directory path when uploading files” URLAction has been set to "Disable" for the Internet Zone. This change prevents leakage of potentially sensitive local file-system information to the Internet. For instance, rather than submitting the full path C:\users\ericlaw\documents\secret\image.png, Internet Explorer 8 will now submit only the filename image.png.To resetting the actual items, suggestions I found were to replace the actual item. So instead of using $s, I just replace the element, with the existing element, causing it to re-initialise.
var htmldb_delete_message='"DELETE_CONFIRM_MSG"';
function fileCheck(el){
    if(el.value){
        var validFile = false;
        var validExtensions = ["csv"];
        var filename = el.value;
        var fileExtIndex = filename.lastIndexOf(".");
        var fileExt = filename.substring(fileExtIndex+1, filename.length);
        for(i = 0; i < validExtensions.length; i++){
            if(validExtensions[i] == fileExt){
                validFile = true;
                break;
        if ( !validFile || fileExtIndex == -1) {
            alert("Invalid Extension. Permitted files must end with: " + validExtensions.toString());
            var htmlContents = el.outerHTML || new XMLSerializer().serializeToString(el);
            $('#P16_BINARY').replaceWith(htmlContents);
}(obviously, replacing what you need to, to suit your page - i prefer scotts idea of passing in supported file types in the function, so would just pass in an array instead; but this is just for demonstration)
with an onchange="checkFile(this)" on the element attributes.
On a slightly un-related note, I found out IE doesn't support the wonderful indexOf function on arrays, that checks for the existence of the value in an array. Sucks.

Search have no access to files in control panel

I operate windows 8. Normally when I need for some files in control panel such as device manager, windows update. All I need is to search it from search button on the right side of windows.
However, one day most of the shortcut if not all are no longer accessible. It says, "This file does not have a program associated with if for performing this action. Please install a program or, if one is already installed, create an association in
the Default Programs control panel."
Please help me, thank you and regards.

Hello LW130003,
Do you mean you have the two issues?
1. Do you mean that you can’t use the search function in control panel? You can only use the search function by using the shortcut Win+S?
2. When you open any shortcut, you will receive error message ‘This file does not have a program associated with if for performing this action..’?
Please take the following steps for troubleshooting:
1. Create a new account, log on the account and check if the issue still exists in the new account.
If the issue doesn’t exist in the new account, please refer to the following article to fix a corrupted user profile.
http://windows.microsoft.com/en-us/windows/fix-corrupted-user-profile#1TC=windows-7
2. If you have issue in open all shortcut in Windows 8, please refer to the following article to restore the registry.
