How can I forward next page, and then pop-up a download dialog box.

My require is that pop-up a download dialog box after forwarding next page.
I have read the coding in the processFormRequest of current page like below,
but I find out that it only can pop-up a download dialog box,
however, it can't forward the next page.
pageContext.setForwardURL("OA.jsp?page=/oracle/apps/xxfm/fm002/webui/TEST001PG",
null,
OAWebBeanConstants.KEEP_NO_DISPLAY_MENU_CONTEXT,
null,
null,
true,
OAWebBeanConstants.ADD_BREAD_CRUMB_NO,
OAException.INFORMATION);
//set default file name: [YYYYMMDDhhmm_IN.EXCEL,FILE_NAME.csv]
StringBuffer strFileName
= new StringBuffer().append((pageContext.getCurrentDBDate().toString().substring(0, 16))
.replaceAll("-","").replaceAll(" ","").replaceAll(":",""))
.append("_IN.").append(strExcelFileName).append(".csv");
//give csv file content
BlobDomain csvFileBlob = (BlobDomain)am.invokeMethod("createCsvFile");
//setenv
HttpServletResponse response
= (HttpServletResponse)pageContext.getRenderingContext().getServletResponse();
response.setContentType("application/octet-stream");
response.setHeader("Content-Disposition", "attachment; filename="+strFileName.toString());
System.out.println("fileName : "+strFileName.toString());
//download
InputStream fileIn = csvFileBlob.getBinaryStream();
long fileLen = csvFileBlob.getBufferSize();
int readBytes = 0;
int totalRead = 0;
byte blockgbyte[] = new byte[65000];
response.setContentType("application/x-msdownload");
response.setContentLength((int)fileLen);
while((long)totalRead < fileLen)
readBytes = fileIn.read(blockgbyte, 0, 65000);
totalRead += readBytes;
response.getOutputStream().write(blockgbyte, 0, readBytes);
fileIn.close();
response.getOutputStream().flush();
I don't know what's matter in the app, can you tell me how to deal with it.
Thanks in advance.

Hi there,
I have a similar requirement. User will download search results in a CSV file after which I want either the page to be refreshed or to be able to goto a Confirmation page or navigate to another page.
I tried using setForwardURL / forwardImmediately / redirectImmediately methods as well as redirectToDialogPage. Since we use pageContext.setDocumentRendered(false); and response.getOutputStream().flush(); methods, the HttpResponse is already committed.
Hence, the page does not redirect to another page as Request is processed and Response is complete. In case of methods like setForwardURL A JSP forward redirects the same request object to the target URL.
Can anyone help here to achieve the expected requirement?
Thanks.

How can I save a page and all its component parts in a single file, like IE does as an MHT - it's much easier for mailing to people where page address not available?? (as in output from an airline booking site, for example)

how can I save a page and all its component parts in a single file, like IE does as an MHT?
It's much easier for mailing to people where page address not available?? (as in output from an airline booking site, for example)
It is simply too painful to have to zip everything up into a single file to send. MHT format has been available for years now from IE, and with every new FF release it's the first thing I look for. I have been using FF for years, and hate having to come out of it, over into IE |(which I even took out of startup) and key everything in again, in order to send somebody something in a convenient format that they can open with a single click.
I can't believe this hasn't been asked before, so have you looked at it and rejected it? Have MS kept the file format secret?
Thanks

This is not really an answer just my comments on your question.
I am sure I recollect efforts being made to get mhtml to work with FF.
Probably the important thing to remember about .mhtml is that if other browsers do support it they may need addons, and may not necessarily render the content correctly/consistently.
There are FF addons designed for archiving webpages, you could try them, but that then assumes the recipient has the same software.
You could simply save the page from FF to your XP pc; then offline open it with and save it using IE, before then emailing using FF, and attaching the .mht or mhtml file that you have now created on your PC.
As an alternative method, in some cases it could be worth considering taking a screen grab of the required page, then sending that to the recipient as a single email attatchment using either a bitmap or jpeg file format for instance.
Something such as an airline booking may be designed with a print option, possibly it could be worthwile looking at sending the print file itself as an email attachment.

How can i hide a JFrame and then Show it again in runtime

How can i hide a JFrame and then Show it again in runtime??
Please, please help me
Its URGENT

Here's even an example:
import javax.swing.*;
public class HideAndShow extends JFrame
     public HideAndShow()
          super("Hello");
          setSize(200, 200);
          setVisible(true);
          try
               Thread.sleep(2000);
          } catch(InterruptedException e) {}
          setVisible(false);
          try
               Thread.sleep(2000);
          } catch(InterruptedException e) {}
          setVisible(true);
     public static void main(String[] args)
          new HideAndShow();
The JFrame will show, then hide, then show again. This is at runtime.

Hi Kurt,
The Mac IIci is not even powering on at all. Tried again with wih a tested power cable and no luck.
I think it's best that take this issue to the Older Hardware Community. Not only did I see a fair number of replacement parts for the IIci avaiable online, but there also vintage external floppy drives as well. I'm not giving up.
Thank you for your time and interest in helping.

How can I select next page when on shopping website

When I'm on a shopping website, like BLoomingdales for example, I can't select next page or page 2. It only stays on the 1st page. Why is this?

Hi,
if you have 3 pages in a smartform do this
DATA:L_NAME(17)   TYPE C VALUE '%HEADER-FIRSTPAGE'.
FIELD-SYMBOLS: <FIELD>.
if plant = '1000'. A page -> B page
ASSIGN (L_NAME) TO <FIELD>.
IF SY-SUBRC EQ 0.
    <FIELD> = 'PAGEA'.
ENDIF.
ENDIF.
else               A page -> C page
ASSIGN (L_NAME) TO <FIELD>.
IF SY-SUBRC EQ 0.
    <FIELD> = 'PAGEC'.
ENDIF.
ENDIF.
Thanks,
Nethaji.

Now my one report called accounts ledger
when i execute the report query it takes 1.03 mins for 515000 records..no issue with it ,
when i execute the report from report desginer for 515000 records its taking 26 mins . It is generating all
32000 pages.
Now same report i run from my web based erp application it takes 30mins to execute 32000 pages now

Hi Mithun,
Here are a few points related to performance issue. These might be helpful.
The performance of a report is related to:
External factors:
1. The amount of time the database server takes to process the SQL query.
( Crystal Reports send the SQL query to the database, the database process it, and returns the data set to Crystal Reports. )
2. Network traffics.
3. Local computer processor speed.
( When Crystal Reports receives the data set, it generates a temp file to further filter the data when necessary, as well as to group, sort, process formulas, ... )
4. The number of records returned
( If a SQL query returns a large number of records, it will take longer to format and display than if was returning a smaller data set.)
Report design:
1. Where is the Record Selection evaluated?
Ensure your Record Selection Formula can be translated in SQL, so the data can be filter down on the server, otherwise the filtering will be done in a temp file on the local machine which will be much slower.
They have many functions that cannot be translated in SQL because they may not have a standard SQL for it.
For example, control structure like IF THEN ELSE cannot be translated into SQL. It will always be evaluated
in Crystal Reports. But if you use an IF THEN ELSE on a parameter, it will convert the result of the condition to
SQL, but as soon as uses database fileds in the conditions it will not be translated in SQL.
2. How many subreports the report contains and in section section they are located.
Minimise the number of subreports used, or avoid using subreports if possible because
subreports are reports within a report, and if you have a subreport in a details section, and the report returns 100
records, the subreport will be evaluated 100 times, so it will query the database 100 times. It is often the biggest
factor why a report takes a long time to preview.
3. How many records will be returned to the report.
Large number of records will slow down the preview of the reports. Ensure you only returns the necessary data on the report, by creating a Record Selection Formula, or basing your report off a Stored Procedure, or a Command Object that only returns the desired data set.
4. Do you use the special field "Page N of M", or "TotalPageCount"
When the special field "Page N of M" or "TotalPageCount" is used on a report, it will have to generate each page
of the report before it displays the first page, therfore it will take more time to display the first page of the report.
If you want to improve the speed of a report, remove the special field "Page N of M" or "Total Page Count" or formula that uses the function "TotalPageCount". If those aren't use when you view a report it only format the page requested. It won't format the whole report.
5. Link tables on indexed fields whenever possible.
6. Remove unused tables, unused formulas, unused running totals from the report.
7. Suppress unnecessary sections.
8. For summaries, use conditional formulas instead of running totals when possible.
9. Whenever possible, limit records through selection, not suppression.
10. Use SQL expressions to convert fields to be used in record selection instead of using formula functions.
For example, if you need to concatenate 2 fields together, instead of doing it in a formula, you can create a SQL Expression Field. It will concatenate the fields on the database server, instead of doing in Crystal Reports.
SQL Expression Fields are added to the SELECT clause of the SQL Query send to the database.
11. Using one command as the datasource can be faster if you returns only the desired data set. It can be faster if the SQL query written only return the desired data.
12. Perform grouping on server
This is only relevant if you only need to return the summary to your report but not the details. It will be faster as less data will be returned to the reports.

Shweta

How can I forward an email and include the attached images?

I sent a client an email with attahced images (I attached the images, pictures I took). The client responded with the images attached to the response. When I try to forward that response to a third party the attached images become place holders only, no image.
Shouldn't my forwarded mail include the images? Short of re-attaching the images how can I get them included in the forwarded email?

I tested a few I forwarded to myself and I could still forward with attachments. You might try Redirecting it (Message menu).

How can I scan to PDF and then save as Word?

Don't know if the above got through or not.
When I scan in documents do I scan as jpg or tif when I want to convert to PDF then to MS Word?

Hi George,
I think I've answered this another post of yours. The best bet is to go straight from the scanner to a format that Word can read (most scanning software should offer that capability), and cut out the middleman (as much as I love Acrobat, it's not necessary in this case).
Best,
Sara

How can I combine the audio and video files from youtube downloads when they don't automatically combine?

I'm using YouTube Video and Audio Downloader. Sometimes the audio and video files combine automatically, sometimes they don't - remaining as separate " DASH - .m4a and DASH - .mp4 ". It used to be that when this would happen I could open up a "ffmpeg" window which would allow me to "manually" convert them to a combined .mp4 file. It was a "drag and drop" type of interface. For some reason I can no longer access that ffmpeg combining function. I tried clicking on ffmpeg.exe. I tried re-downloading ffmpeg several times, both from the Downloader options tab and from the ffmpeg website.
Thanks for your help.

Sounds like a question for the developer of the video download add-ons that you have installed.

How do I create a signature,and then add it to an e ailed document?

How can I create a signature and then use it to sign a document in e mail?

Not sure I understand the question correctly.
Open Mail and click on Preferences under the Mail menu. Click on the Signatures icon in the toolbar. You can set up your signatures there.
But if you are talking about adding a written signature, then you cannot do that within Mail. You would need to scan in an image of your written signature then manually add it to a signature you create in mail as a graphic image. That seems to work.

VB CS4 - How send many textframe to a document to fill page and then another

Hi,
Sorry by my bad english, I'm using CS4 and vbscript.
Need to take information from several fields in a database and send it to an Indesign document. Progressively fill a page and then another.
How do you add a textframe automatically for each field and the pages needed.
With my current code, I can put a box on every page. But I want to put the text fields below and once you fill the page, switch to another.
Thanks.
Jorge
Current code:
For i As Integer = 0 To myDataSet.Tables(0).Rows.Count - 1myPage = myDocument.Pages.Item(i + 1)
myTextFrame = myPage.TextFrames.Add
Dim myArray1 As String() = {"4p", "4p", "60p", "20p"}myTextFrame.GeometricBounds = myArray1
myTextFrame.Contents = myTextFrame.Contents + (myDataSet.Tables(0).Rows(i).Item("name")).ToString + vbCrmyTextFrame.Contents = myTextFrame.Contents + (myDataSet.Tables(0).Rows(i).Item(
"adress")).ToString + vbCrmyDocument.Pages.Add(idLocationOptions.idAfter, myDocument.Pages.Item(i + 1))

The Quiz Results slide's Continue button actions are set under Quiz Preferences > Pass or Fail > If Passing Grade etc. By default, the Continue button is set to just continue on to the next slide after the Quiz Results.
After the user clicks the Continue button on the Quiz Results slide any Pass/Fail actions you've set up there will be evaluated and executed.
So if the user achieved a passing score, and you set up an action such as Go to URL in Current Window for that case, then the user should find themselves redirected to that URL. If there was a different action for Failure, and the user failed, then that should happen. But either of these will only happen after the Continue button is clicked.
I tested this by setting www.google.com as the go to URL and it worked. To see if the URL is the issue, try using another URL that you know everyone can get to. If that works, try to find out why the URL you want to use is not working. If no URL works, something else is interfering with the action.
