Using a %% tag to write vb code in aspx file

Trying to create a pdf from an rpt. I used the wizard wich generated the code within the div tags. I authored the code inside the <%%> tags. I am following an article written by Edward Tanguay-How to create PDF files from ASP.NET pages. Can I refer to the Crystal Report filename outside the div code-block and refer to those elements inside my <%-block. Here is the code<hr /><%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %> <%@ Register TagPrefix="CR" Namespace="CrystalDecisions.Web" Assembly="CrystalDecisions.Web, Version=10.2.3600.0, Culture=neutral, PublicKeyToken=692fbea5521e1304" %><%@ Import Namespace="CrystalDecisions.CrystalReports.Engine" %> <%@ Import Namespace="CrystalDecisions.Shared" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"><title>Test Report</title> </head> <body><form id="form1" runat="server"><div><CR:CrystalReportViewer ID="CrystalReportViewer1" Runat="server" AutoDataBind="True"Height="947px" ReportSourceID="CrystalReportSource1" Width="845px" BackColor="Beige"/><CR:CrystalReportSource ID="CrystalReportSource1" runat="server"><Report FileName="CrystalReport1.rpt"></Report></CR:CrystalReportSource> </div><% Dim myDoc As ReportDocument = New ReportDocument Dim ExpOpt As ExportOptions = myDoc.ExportOptionsmyDoc.Load("CrystalReport1.rpt") ExpOpt.ExportFormatType = ExportFormatType.PortableDocFormatExpOpt.ExportDestinationType = ExportDestinationType.DiskFilemyDoc.Export()%> </form><button title="Click Me">Do me again<img src="icon-adobe-acrobat.gif" alt="WoW" /></button> </body> </html>

You're trying to put code tag in an auto-generated CrystalReportViewer aspx page, and putting code in the code tag.
That won't work - ASP.NET won't work like classic ASP.
In VS, drop a component - like a Button - on the page, then put your code in the codebehind for the click event for the Button.
Sincerely,
Ted Ueda

I am using Firefox 4.0. Face problem opening .aspx file / application, any solution?

webpage in form of Pop-up window (.aspx file ) is not getting opened in Firefox 4.0 browser. please suggest solution. The same webpage opened when opened with Google Chrome Browser 10.0.648.151.

If text on web pages isn't visible then you most likely have a problem with the font that is used on those pages.
As a test you can try to disable the website fonts and if that still doesn't work then try a few different default fonts.

Using filewriters to write to an already opened file

Hi,
I have used a filewriter to write some message to a file in a loop. Will i be able to write the messages for the rest of the iterations, if after the first iteration , i open that file in a notepad and check out if the message is being written properly?

If you open the file before the filewriter opens it, the file might get locked causing an IOException when you try to open the file. But that only happens when the file is locked by the program that opens it. Notepad doesn't doen't lock the files it opens so you can safely open it. You won't see the updates that are made to the file after you open it until you reopen the file.
You could also open it in you favorite browser, then you can hit the reload button to see the latest version.

Write PHP code above HTML tag

I've created a toolset that allows me to add Form fields that
we use in our system. But now I want to take that a step further. I
want to be able to write corresponding PHP code above the HTML tag
at a specific location. This while looping through the formfields
in the form and dynamically write the INSERT and/or UPDATE query.
The last bit I can probably figure out. What I would like to
know is how to write the code above the HTML tag between <?
?> or with a search/replace of the INSERT or UPDATE line in the
code.
Can anyone give me some hints or tips on this?
Thanks in advance!

Hi Bahare,
The <script> tag is used to define a client-side script, such as a JavaScript.
The <script> element either contains scripting statements or it points to an external script file through the src attribute.Common
uses for JavaScript are image manipulation, form validation, and dynamic changes of content.
You should write C# code inside asp.net (C#)(.cs).page. For more infomation,Please check

TS1292 Purchased gift cards about a year ago. Misplaced two of them. Found them yesterday, tried to use one today. Invalid. If the money is tagged to the card code why is it invalid? Now have to take photos of both sides and find receipt? Guess out $20?

Purchased gift cards about a year ago. Misplaced two of them, but Found them yesterday. i tried to use one today. Invalid. If the money is tagged to the card code why is it invalid? Now have to take photos of both sides and find receipt? Finding the receipt might take as long as .finding the cards. If I paid hard earned money for the card from a computer company why would that card not be in their data base waiting to be activated? I guess I am out $20 to Apple for not activating immediately! My account was hacked once so I won't put a credit card in and live with gift cards. Now I am getting hit for $20, two gift cards for ten each. I now question who and how people are making money?? Is my only solution, buy card, redeem code instantly, purchase item?

 Thanks

I have done exactly that in one of my applications.
I have extracted the image from the database as a byte array, and displayed it using a servlet.
Here is the method in the servlet which does the displaying:
(since I'm writing one byte at a time, it's probably not terribly efficient but it works)
 private void sendImage(byte[] bytes, HttpServletRequest request, HttpServletResponse response) throws IOException {
 ServletOutputStream sout = response.getOutputStream();
 for(int n = 0; n < bytes.length; n++) {
 sout.write(bytes[n]);
 sout.flush();
 sout.close();
 }Then in my JSP, I use this:
<img src="/path-to-servlet/image.jpg"/>
The name of the image to display is in the URL as well as the path to the servlet. The servlet will therefore need to extract the image name from the url and call the database.

Accessing a File within a zip, which was archived using Applet Tag

Hi,
Could Any one please tell me, How to Access a File from within an Applet. The File resides inside a zip which was Archived using <Applet> Tag.
Actually, I want to write an application which runs both online and offline. So I have chosen Applet and All the files Which I need are zipped and is Archived through <Applet ARCHIVE="example.zip">.
Now I want to access those XML files which are inside example.zip from my Applet.
How can I do that?
I think I will get security Exception.

Did you already try signing a jarfile? If no ->>
You can call a class inside a jar-file within the applet.
if this class should be able to acces files the jarfile
first has to be signed. to do this, you must generate a key.
the complete work:
1. write your applet
2. write a html-page with following code:
<APPLET code="guestbook.class" archive="guestbook.jar" width=600 height=400></APPLET>
3. make a zip-file with the guestbook.class, guestbook.form, guestbook$1.class, guestbook$... and rename it to guestbook.jar
4. in the console type:
keytool -genkey -alias YOURNAME
5. sign the key to your jarfile with:
jarsigner guestbook.jar YOURNAME
6. try the applet. a warning should appear which you have to answer
with YES then it should work
my trouble is that i cant acces files anyway because right now i don�t
alreadv have the clue to get the right (absolute?) path for the file. means i get an ioexception because the applet cant find the file :-((
does anyone know how to solve this problem then? my code is:
FileReader Stream = new FileReader("/members/Ui97u8g4f6b89mj90kh5gbr4ecf6KXC4/guestbook.txt");

How can I write HTML code in this forums

Sorry but I didn't know where to post this thread.....
How can I write HTML code in this forums?

Hello,
Every piece of code in your post should be wrapped with the forum tags [ code] and [ /code], without the blanks.
In case of the <a> tag, that is not enough. In this case, you have several options. The most elegant one is to use the entity name for the less-then sign - & lt; - without any spaces. Other options is to add a space between the less-then and the ‘a’ character (and make a note of it) or change the less-then character with a left bracket one.
When posting code, you should always use the forum preview option, just to make sure the forum software “understood” your code correctly.
Hope this helps,
Arie.

How to use nested tag in Struts

Hi..
Can any one guide me how to use nested tag in Struts. So far i already tried bean tag with no error but when i try to use nested tag i got error like
javax.servlet.ServletException: Cannot find bean: "" in any scope
Below are my class:
action class
session.setAttribute ("MyDetailList", detailList);
JSP page
<logic:iterate id="list" name="MyDetailList">
Company ID : <bean:write name="list" property="companyID" />
</logic:iterate>
For bean tag, i got no error at all and below are my code for nested tag
action class
session.setAttribute ("MyDetailList", detailList);
JSP Page
<nested:nest property="MyDetailList">
Make : <nested:text property="make"/>
Car ID : <nested:text property="carID"/>
</nested:nest>
When i run the code, i got error message
javax.servlet.ServletException: Cannot find bean: "" in any scope
Any body can help me?
zul

what am I doing wrong?You will notice above that I mentioned
YOU CAN'T USE CUSTOM TAGS AS ATTRIBUTES TO OTHER CUSTOM TAGS
(was that loud enough for you to notice this time)?
Try
<html:text styleId="instruction" styleClass="text" size="50" name="instruction" property="value"/>
//or
<html:text styleId="instruction" styleClass="text" size="50" property="instruction" value="<%= instruction.getValue() %>"/>
better alternative: populate your formbean with your action and just have:
<html:text styleId="instruction" styleClass="text" size="50" property="instruction"/>
If you set the "instruction" property of your formBean in the action, the value will be automagically reflected here.

Where i shall write html code in jdeveloper

Hello,
please tell me where i can write html code in jdeveloper.
Thanks

Hi catalina,
Html tags should not be used directly inside ADF faces pages which may lead to some undesirable results instead you can use ADF Faces tags itself using which you can do what ever you wanted to do with html tags.
If you still need to use html tags, you can use ADF Faces html tags.

Why does people use JSP Tag for their JSP page? (Urgent)

I don't know what benifit if I am using JSP Tag.
If anyone knows, pls give me an idea and the advantage of using JSP Tag in JSP Page!
Thanks in advance!

You have to read a little about JSP, JSP stands for JavaServer Pages, you can use jsp tags and you can use java code. If you dont want to use jsp tags then you should just write html file, if you just want to use java, then write java class or a servlet.
The need for jsp arised because people were inserting html code inside a servlet class..a big no no..and a headache. JSP separate model from the view...read a little about MVC-2 model view controller pattern.
Also read some tutorial on this website...good luck
