Image taken from server and display on the screen

Hello Sir

I'm new to the development of Blackberry, I use a webservie that returns the image in . Its a Web service written in DotNet Framework. I'm trying to convert bytes it so that I can conver bitmap and use it on the screen.

I think I'm losing a date when the dat of conversion to Byte]

connection_for_image image_connection = new connection_for_image();

raw Byte [] = image_connection.get (URL);
Dialog.Alert ("control returned 1 size =" + raw.length);

try {}

Bitmap_image bitmap = new Bitmap (Bitmap.ROWWISE_MONOCHROME, 50, 50, gross);

Image BitmapField = new BitmapField (bitmap_image);
Add (image);

} catch (Exception e) {}
Dialog.Alert ("catch" + e.getMessage ());
}

After running the above code a few image is displayed in black and white, but even once, is not the image I am downloading from webservice.

In the connection class that I'm parsing the data type in bytes using following code

data Byte [] = null;

I have String = d.MySplitName (content, "",")<>
data = i.getBytes ();
return data;

Here, I'm a little frustrated because you don't seem to listen to what I tell you.

"How to convert byte [] Base64Binary data.

"Is there a way by which I can convert the base64Binary byte data.

Please read carefully what I suggested that you make. You should be able to determine the raw bytes that has your Web server. The Web Service then converts it to text he sends you. You should be able to convert it to bytes that were originally used. You have enough information in this thread already do. Please confirm this part of the treatment before you do anything else.

"then use these data to display the byte [] in the bitmap file.

That's where I think your problem is. Look at the code I gave you in the last post. But you will need to know the format of the raw bytes that are stored on your Web server and sent to you. Then find a way to convert them into a Bitmap image on the device - method may depend on how the bytes are stored on your Web server. It might be that the bytes that are sent to you are already in a Blackberry bitmap format, but I doubt it.

So please make sure that you have correctly found the bytes of the raw image. When this is correct, you know that your network stuff working. Once you've done that, then you have to find a way to convert the bytes of the Bitmap image.

If the byte [] is supported by JSR 172 is not relevant at this stage.

How to retrieve the image BLOB from database and display the image in rtf file using the Oracle XML Desktop 5.6.2 publication server?

Hi all

Here I have the image BLOB in the database files,

I want to show the image to PDF using file to rtf using Oracle Xml Desktop Publisher,

Hi all

I found the solution for reading Image BLOB of data base & display in Pdf format.

(1) read the image from DB.2) and then copy the picture using IO. UtilsCopy method to copy the picture

(3) then encode with base64 converter then you will get the tag XML with Base64 as string then placed in your XML Code & preview the output, you will find the image

Photo = (BlobDomain) currentRow.getAttribute ("Image");

ByteArrayOutputStream OutputStream = new ByteArrayOutputStream();

	Byte [] imageByte;
	Byte [] b = null;
	try {}

	IOUtils.copy (photo.getInputStream (), outputStream);
	BS = outputStream.toByteArray ();
	outputStream.flush ();
	System.out.println("==="+BS.) Length);

Hello

I found the error.

It's in the URL sent by the server.

The URL consisted of http://google.com

But the format required to retrieve the image on several device would be http://www.google.com.

Thanks for anyone who tried to help him.

Apex 5 display image field, control width and height on the form page

Hello everyone,
I try to display the image from a blob directly column on the page, it does not work well, here's my question, how can control the width and height of the screen image field, because its changing dynamically the size of the screen according to the original dimensions, I want to set the dimensions.
Any help will be appreciated.
Concerning

set the width and height attributes in the attributes of the image html elements

for example Width = "200" height = "100".

In the latest versions of FireFox, there's a display option which allowed a change in the size of the fonts and objects on the screen temporarily on the fly. This seems to be missing from version 6.

You forgot to tell us something about your computer. You hear any sound from the computer at all once you turn it on, it? It sounds like the hard drive turning upward? You see absolutely nothing on the screen? Be more descriptive and include information about your computer (computer desk/computer laptop/brand-model), his age, and precisely what happens when you turn on the computer. It is a hardware problem and narrowing of component that failed is not possible without more information from you.

Images JPG, stored in DB, are not displayed on the screen/image.
Hi friends,

I have a form to save and retrieve images (JPG, GIF, TIF) to and from the DB, using WEBUTIL_FILE_TRANSFER. CLIENT_TO_DB and CLIENT_IMAGE. WRITE_IMAGE_FILE respectively.
It works fine, but with few JPG images, it stores in DB, but not displayed on the screen/image.
Second, if I try to retrieve and write the JPG to the operating system (using CLIENT_IMAGE. "" WRITE_IMAGE_FILE), he invited error "FRM-47101: cannot write the file image.

Environment:
Forms [32 bit] Version 10.1.2.0.2
Operating system XP Pro 2002 SP3
Oracle DB 11 g Enterprise Edition rel. 11.1.0.7.0 - 64 bit

Any help will be much appreciated.
Hello

Some recent JPEG formats are not supported by the forms. I can't tell you exactly what, but I have already noticed that some images could be made only by the forms. The only solution is to save the images with another program to transform the internal format to a recognize an or use a Java Bean able to read all of these formats.

Loginoff, save your settings and Windows stops no display on the screen, every time I stop my Windows XP Professional SP3

Hi all

Hi Patfaucher1974,

Your question seems incomplete. When you say "Windows is no display on the screen stop" means that you do not get the screen that says "closing Windows"?

-You are unable to shut down your computer?

-If so, can remind you to make changes to your computer between the calendar when things worked fine and now?

Try the steps listed in the article below and check if that helps you:

Firefox will not display on the screen even though with Process Explorer, I see active Firefox.exe but no CPU usage

I use Firefox as default browser v10.0.2 on Dell XPS8300 Intel Core i5 and Windows 7 Ultimate and Compaq Presario CQ57 IO IO Intel Core i3 and Windows 7 Home. More frequently on the (approximately 90% of attempts) that Dell (50% of attempts) Firefox will not display on the screen when I click the icon. Cannot display other programs when it happens. I expressly say display because I believe that Firefox has started. To work around the problem, I installed Process Explorer on both machines and launch this program first, then click on the Firefox icon. When the problem occurs I see process Firefox.exe in the list of processes; some CPU consumed but, then, no CPU activity. If I click on the Firefox icon, yet another process opens in the list of processes, but with the same answer - some consumed CPU and then no CPU activity. If I have 2 processes running and kill the process from the 1st, the 2nd poster and then everything is normal. If I do not open it treat a 2nd, but kill the 1st process then click the Firefox Firefox is displayed and all then is normal. This problem has occurred since the original on the two new machines installation. I have updated the video drivers on both computers.

OK, let's see if we can solve this problem and make it work for you!

First of all, if you start Firefox in safe mode (restart your computer first, then when you open Firefox, hold down the SHIFT key) it starts more reliable? This is usually caused by a defective module. If this does not help, then restart Firefox, go to the Firefox, then add-ons button and disable your extensions one by one until you find the troublemaker.

Also, try to update to Firefox 11, it has several bug fixes that might make life easier here.

Just as a few troubleshooting steps base to ensure that we have all the bases covered,
Run all Windows updates, install all required service packs, etc.

Update all of your plugins (Flash, Java, etc.): http://www.mozilla.org/plugincheck/.

Download and install MalwareBytes Anti-Malware, run a full scan. http://www.malwarebytes.org/. This check allows that there is no virus on your computer, causing problems. You can uninstall this program after having cleaned the infections.
