Saving images on my database and calling the open file dialog

i want to be able to save image in my database or alternatively save them on a file system. meanwhile i want to allow them choose the name of the image in the folder by using the win_api_dialog.open_file. My platform is win2000. do i need to add any other thing to this like a particular library or just anything. please i need this help urgently.database os is unix ware.

Hello,
You can do this without using library. Suppose you have a table with BLOB data type column and one form which has image box to display and store image boxes.
Now by using READ_IMAGE_FILE read picture file. To write picture to file use WRITE_IMAGE_FILE. and
if you want to give users open file dialogue box then use GET_FILE_NAME builtin.
All the best.

Folder appears in Windows Explorer, but not in the Open File dialog

Hello,
I hope this is the right place to post this. If not, please let me know where is.
A friend just showed me a weird problem he is having with his computer. He is using Windows 7 pro, and has a folder under My Documents, in which he keeps his work files. He emails these files using Gmail, which he accesses via Internet Explorer.
All worked fine until a few days ago, when he noticed that when he clicked the link in Gmail to attach a file, his folder wasn't listed in the Open File dialog. He looked in Windows Explorer, and could see the folder OK. I tried opening Word and using the Open
File dialog there, and the folder wasn't visible.
If he clicks in the address bar, and adds the folder name to the path, it opens the folder, but shows it as empty. I actually has two subfolders. If he adds the name of a subfolder, then the Open File dialog shows the files in that folder.
I checked the permissions on the folder, and couldn't see anything odd. What I don't understand is how the folder can be visible in Windows Explorer, and not in the Open File dialog.
Anyone any ideas? Thanks

I can confirm - I'm having the exact same problem.
When I try to lookup or save a file from an IE file dialog some folders do not show up. I can type the folder name into the directory field and it then goes there, but this assumes you know the directory name and it's a PITB.
Firefox can browse to the directory directly.
It would be interesting if anyone else found a fix for this - I'll post here again if I find out more somewhere else, but there are not too many threads out there as far as I have found for now.
Found a solution over at answers at Microsoft dot com. (can post links here yet - will update once I can)
In short: There's a fast fix for this issue by resetting a hidden flag that IE sets for some folders. I believe this part of the "protected mode" feature, though I can't confirm and also have no idea how this would protect me from any intruders,
if only (unimportant) subfolders are protected ...
Anyway - if you know the name of the missing folder (e.g. from browsing the directories form windows explorer): in the parent directory that has the folder missing do a Search (in box at top right) for the missing
folder name. In my case the hidden folder shows up in the search - now right click -> Properties -> clear hidden flag. Note: this "hidden" flag is independent of the flags set in windows explorer - that's why you have trouble going there with IE and not
the file explorer from the desktop.

What does the open file dialog do 'under the hood' and is there a way to simulate it

What does the open file dialog do 'under the hood' and is there a way to simulate it?
I have a bug in my code (that I've posted about before, here) which I can't fix at the moment, but I do have a workaround.
Briefly, the bug:
I call a dll from a function node, to initialise and run a spectrometer. If I start up the PC, LabVIEW and run my vi the code runs without complaint, the first call to the dll to initialise the spectrometer doesn;t return an error but the spectrometer is not detected either.
I've tried various solutions, see the link above, and none work
The workaround:
If, at any time before running the code containing the function node I open an 'open file' dialog window, select the dll and click ok/hit enter then everything is fine. When I run the main code the spectrometer is detected.
I use an express vi to open the file dialog, I specify the start path and file name as constant inputs and just click ok/hit return when the dialog pops up. I don't do anything with the dialog outputs. In fact the vi that contains the open file dialog can be run before the project containing the bug is even open.
I have to do this everytime I turn the PC on.
So, either
1) Can somewone suggest a fix for the original bug?
2) What is the easiest way to simulate the enter keypress when the open file dialog pops up
or
3) Can someone tell me what the open file dialog does under the hood that somehow causes the dll to work and can it be simulated in straight LabVIEW
I suspect that the dll itself is dodgy ( I have in the past talked to the supplier but not got very far, and I will try again but I would like a quick, temporary solution too). I'm guessing that the file dialog is making some kind of check on the file, and possibly registering its presence with the OS (winXP). I tried using the file/folder exists vi to see if checking the file like that worked but no luck.
Any help greatly appreciated.
Dave

Hi David
I am very conscious about thread hijacking but this sounded like my issue so I hope you dont mind me asking about your issue. I am hoping that you have a spectrometer from the same vendor as me and its not just me seeing an Error 1097 issue. My spectrometer is from a company called Stellarnet.
So far I have unable to get it to work with other VIs. There is one condition where I can get it to work but its no good for me.
Case 1
I open the VI in a fresh labview environment with no other VIs in memory. The code runs with no issue.
Case 2
Labview is not opened. I double click the spectrometer VI in windows explorer. The VI opens but it fails to run resulting in Error 1097. Personally, I dont see the difference between this and Case 1 above and yet it fails.
Case 3
If I already have other VI's in memory and try to load the spectrometer VI and run it fails with Error 1097. This case is the one that most important to me. I have a test executive that will load test VIs dynamically and I can't get this to work. Same problem Error 1097.
I wanted to share what I have seen with you and to let you know that maybe somebody else has the same issue. I am convinced its the DLL but the vendor dis-agreed saying it was LabVIEW. I couldn't convince him otherwise.
Thanks in advance

Some qt only programs are crashing opening the "Open File" dialog

Hello Archers,
I'm having some trouble to find out what's crausing the crashes, so i can properly fill a bug report upstream.
Here is the issue:
* After an upgrade from glibc 2.13-5 to glibc 2.14-4, some qt-only apps are crashing when i open the "Open File" dialog. This only happens when using specific KDE 4.6.4 or KDE 4.6.5 styles, like Oxygen and QtCurve.
* Before i upgrade KDE from 4.6.4 to 4.6.5, i downgraded glibc and its dependencies to glibc 2.13-5 and the bug was gone. After upgrading KDE to 4.6.5, i didn't try the downgrade again because KDE 4.6.5 requires glibc 2.14 and the process of downgrading become unsustainable.
* I tried removing the crashing apps data from my home directory and the crash still exists. I also tried to create a new user and start the apps from that new environment and the apps crashes, so the bug is not user-specific.
* I tried replacing the binary nvidia driver with xf86-video-nouveau but the issue persists.
* The apps crashing (and not applying the kde theme) are the following:
=> opera 11.50
When opening the "Open File" dialog, it crashes with the following message:
------------- begin ---------------------------------
$ opera --sync

(operapluginwrapper:2349): Gdk-WARNING **: GdkWindow 0x740001c unexpectedly destroyed
The program 'operapluginwrapper' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
(Details: serial 547 error_code 3 request_code 18 minor_code 0)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)
------------- end ---------------------------------
=> vlc 1.1.10
When opening the "Open Directory" dialog, it crashes with the following message:

------------- end ---------------------------------
* Using other qt-only apps, like qmmp or UMPlayer the bug doesn't occur.
So, what do you thing of this? Am i the only one with this issue? I already reported the bug report on https://bugs.archlinux.org/task/24991 and https://bugs.opera.com/wizard/, but since i latter found out that this is not opera specific, i don't know where to fill the report.
Thanks in advance.

i had to install vlc and opera to test - but i'm afraid i don't get the errors you are seeing.
so far, qt designer is the only application i've found that crashes when opening file dialogs.
Ok, thanks for helping.

How can I change the default "file type" in the open file dialog when using Firefox on certain web pages?

I work for a bankruptcy attorney. We use the Court's file upload to file our documents. When I am on the Court's site and I have to pick a file to upload, the "open file" dialog box pops up. In Firefox, the default "file type" is always "image" files. I need it to be "all files". How can I change this setting?

Two observations.
First — "Tools-> ...." is specific to Acrobat X and XI. It did not exist prior to Acrobat X.
Second — Acrobat 9 Pro / Standard (nor earlier release) does not support viewing a PDF page containing a scanned image and performing a right-click ... Save Image As.
The context menu provided by Acrobat 9 Pro with a right-click on a scanned image is:
The context menu,from a right-click with the TouchUp Object tool selected, for Acrobat 9 Pro is:
So, to paraphrase what Paul Harvey used to say ... What's the rest of the story?
Be well...

When I hit the escape key to close out the open file dialog box, firefox hangs or crashes.

When I open the "open file" dialog box using the ctrl+O and then hit the escape key to exit the box, I get an error message which I'm not able to paste here.
it says something about a runtime problem and if I try the same thing again to reproduce the problem, it will sometimes just hang and windows vista will tell me the program is not responding.
I've checked to see if there are any crash IDs but none were found for this time frame.
I have even disabled all add ons.
I'm currently using vista 64 bit edition and Firefox 6, beta edition.

Hi,
Please also try right-clicking on the link corresponding to the language version and '''Save Target As''' to save the Firefox installer. If the problem persists, posting [http://answers.microsoft.com/ here] would also be helpful.

I want to change the default file type in the Open File dialog - e.g. from Word to All Files

I want to change the default file type in the Open File dialog - most recently specifically in Adobe Acrobat, from Adobe Files to All Files, so I don't have to do it again and again manually. Is this possible? Is it an OS setting or an app-specific setting?

The Apps set the default to the file type it can open, sort of. However, there normally isn't a type specified. All document types that the app can handle will be offered.
Adobe, and Microsoft, tend to roll their own dialogs, so they may not be standard. I don't have Acrobat, so I can't verify that. If Adobe is puting a file type selector in their open file dialogs, it would be up to them to store the preferences.
EDIT: I checked Reader, and i see what you mean. Not terribly useful.

Diappearing photos replaced by an exclamation point within a triangle. Prior to loading Lion I could put the image number in finder and locate the original file for that photo. How do I restore photos now?

I had problems with photos disappearing and being replaced by an exclamation point within a triangle. I can see the photo in the thumbnail summary but when you click on it, the screen goes black and the exclamation point within a triangle appears along with the info on the original image number (i.e., img_1120.jpg). Prior to loading Lion, I could go to Finder, enter the image number and locate the original file for that photo. I could then restore it for editing, copying into Print Shop directly, etc. That no longer works after installing Lion. How do I restore photos now? I have 100s of photos that I have been going back to the original files and restoring and I am frantic that I will no longer be able to get to the original files. Please help! Thanks

The ! turns up when iPhoto loses the connection between the thumbnail in the iPhoto Window and the file it represents.
What version of iPhoto? Assuming 09 or later:
Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Rebuild iPhoto Library Database from automatic backup.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one. .

My mac repeatedly reflows the screen and all the open file windows. why is this happening and how do I fix it? it happens while using Adobe InDesign 3.

this happens from time to time and I think in the past I have done a restart to make it stop. it's possible it only happens while using Adobe InDesign CS3 but I have not watched diligently enough to say for sure. the hard disk repeatedly, every 30 seconds or so, spins up and the entire screen reflows, finishing on the finder with open windows all opening in order. everything moves. then I need to go back to InDesign only to have it happen again. I don't necessarilly touch any keys or the mouse. as I type here it has stopped so maybe it really is an InDesign issue. does anybody know what's going on?

BDAqua and old comm guy,
thanks so much for the good advice. I used both of these and now the problem has stopped. first I checked the finder crash logs and yes, my finder had been crashing repeatedly.
next I removed the preferences files from the library, rebooted from the CD and ran disk utility to repair preferences. since then my computer has been stable.
there were some preferences that didn't get repaired when I ran disk utility. I am copying them here to refer to later if I need to. I don't understand what these mean to me:
Warning: SUID file "System/Library/Filesystems/AppleShare/afpLoad" has been modified and will not be repaired.
Warning: SUID file "System/Library/PrivateFrameworks/DiskManagement.framework/Versions/A/Resources /DiskManagementTool" has been modified and will not be repaired.

What is the open File Dialog box

I am using a "File Browse..." item. With firefox a user can click on the provided Browse button or the corresponding text area to choose a file. However with IE7 the file dialog box on appears if the user clicks on the browse button.
Can someone tell me what javascript can be used to open a file dialog box? (what is called when the browse button is clicked)
Thanks.

Thanks Carl,
I thought APEX was doing some crazy javascropt stuff because I forgot about a style I had set.
Anyway, I was getting an error if an IE7 user types in a crazy string into the file dialog box and hit submit (since it is not a file). So instead of preventing it I just used a try/catch block in my custom doSubmit. If anyone else runs into this here is a little javascript to help:
(I am used a uploading image, Carl has an example of that somewhere)
<pre>
function doSubmit(r) {
if (ser_changed.length > 0) {
     if (r == "UPLOAD" || r == "SAVE_CHANGES" {
          flowSelectAll();
          $x_Value('pRequest',r)
if (r == "UPLOAD") {
try {                              /// this is where my fix is.
          document.wwv_flow.submit();
catch(err) {
html_HideElement('AjaxLoading');
alert('Invalid file');
} else {
document.wwv_flow.submit();
               }//save changes and stuff as request.
else {
          var ans = confirm("You are about to exit the page without saving your changes!" + '\n' + "Click cancel to return to the page.");
          if (ans) {
          flowSelectAll();
          $x_Value('pRequest',r);
          document.wwv_flow.submit();
          }//when yes!
$x('CANCEL_BUTT').disabled=false;
               }//not save changes and stuff
          }//when there were changes made.
          else {
                         flowSelectAll();
          $x_Value('pRequest',r);
          document.wwv_flow.submit();
          }//where there were not changes made
     }//doSubmit
</pre>
<pre>
function html_Submit_Progress(pThis,topass){
          if(pThis.nodeName=='INPUT'){pThis.value='...Loading...'}

Greyed-out Files in the Open File Dialog Box

I recently installed Logic Express 8 and then attempted to open a Garageband project. I used 'File Open' from the menu. When I click on my Garageband folder the dialog box shows all the .band files as greyed-out. This is also happening with older version of Logic Express such as the Tutorial song file.
Anyone with a idea or seen this before?

It seems to be a rather glaring bug in LE8 that will hopefully be fixed in the next update. In the meantime you can open LE8 files by going to File/Open Recent after launching. From there, other files can be opened by clicking on the Media button on the top right and then the Browser tab. Find your file & double click to open it. Also, you can just double-click a file on your desktop to launch Logic.
GarageBand files can be opened by right-clicking and selecting "open with LE8."

Why the open file dialog form goes to SAP background.

I created a addon form and there is a button to open a file dialog. When I click it, this dialog went to the background of SAP. How to fix.Please

Setting up a relative path in the "open file" dialog window

Hello there,
I want to open a PDF file through a clickbox out of
Captivate. The path I have to put in there has to be absolute, I
guess.
Is there any possibility to put a relative path in there?
To get you a clue, what I want to do with that, here is my
intention:
I want to build up a splash screen for a Auto-Run-CD, where I
want to link some reference documents.
Thanks in advance for your suggestions,
Markus

Hi Markus
Normally all you have to do is just type the file name of the
file. Then ensure the Captivate output and the file you are linking
to are in the same folder. If you don't like that approach, I
believe Captivate will accept another relative path that is set up
perhaps like this:
Root level of CD
Documents folder
So the link would look as follows: Documents/SomeFile.PDF
Cheers... Rick

Saving word doc in database and retrieving

hai all,
Is it possible to save a word file in database and retrieve the word file in web dynpro application?
Thanks n Regards
Sharanya.R

Hi,
To save the wordfile to the database make use of lob types.
Make use of JDBC to do this.
retreiving
Make use of JDBC to fetch the previously saved doc.
Populate a context of type IWDResource(Nw04s onwards) or Binary(Nwo4).
Set the appropriate mime type
Create a filedownload and bind this.
