Can a link only change one cell in a table?
I've been learning Dreamweaver from a textbook, but I'm still pretty new to it, and I'm not sure what terminology to use here. I want my site to have a link that just changes one cell in a table when you click the link, rather than having it go to a whole new page. For example, you click a link and a picture changes but the rest of the site stays the same. So far, I've been doing this by just making several duplicates of an html file, and then just changing that one cell in each copy. It works, more or less, but then whenever I want to make a change to my page, I have to make the same change in all the copies. There's got to be a better way, right?
If this is too complicated to explain in a forum, perhaps someone could just tell me if there's a term for what I'm trying to do, and then I can just look for it in my book or search for it online.
Thanks for your help. Oh, and the version I'm using is CS5.
What you are asking for is called a 'disjoint rollover', which means 'something happens over here, and the effect is seen over there'. It's simple to do even manually. Take a look at this page -
http://www.murraytestsite.com/locrian.html
The code on the page is this -
<!doctype html>
<html>
<head>
<meta charset="UTF-8">
<title>Untitled Document</title>
</head>
<body>
<p><a href="#" onclick="document.getElementById('image').src='_img/masthead-logo1.jpg'">link</a></p>
<table width="347" border="1">
<tr>
<td> </td>
<td> </td>
<td> </td>
</tr>
<tr>
<td> </td>
<td> <img src="_img/masthead-logo.jpg" width="347" height="120" alt="" id="image"/></td>
<td> </td>
</tr>
<tr>
<td> </td>
<td> </td>
<td> </td>
</tr>
</table>
</body>
</html>
I used a table because you specifically asked about tables, but I wouldn't recommend using them for anything other than tabular data, and certainly not for general layout. The code could be re-written like this to completely eliminate the table -
<!doctype html>
<html>
<head>
<meta charset="UTF-8">
<title>Untitled Document</title>
</head>
<body>
<p><a href="#" onclick="document.getElementById('image').src='_img/masthead-logo1.jpg'">link</a></p>
<div><p><img src="_img/masthead-logo.jpg" width="347" height="120" alt="" id="image"/></p></div>
</body>
</html>
Better, huh?

You can use the config nodes in SPRO to set up number ranges for your cash journal documents.
IMG Path> FI Global Settings>Bank Accounting>Business transactions>Cash Journal
Define Number Range Intervals for cash Journal documents
Define Numbering Groups
Define Number Ranges for numbering groups
After defining the number group here, you assign that in "Set up Cash Journal" Check if there is any clash anywhere in your configuration for different cash Journals.

HT3702 Is there any limit to the number of itunes account that can be linked to the one credit card?
Hi. Does anyone know if there is a limit to the number of itunes accounts that can be linked to the one credit card?
Thanks,
NelliemayCraig,
It was image.cpp line 2770. I am told (by another person in the company that has seen this) that it has been seen on several machines, always PXI controllers, but not on all PXI controllers. I am told that it is not always image.cpp that reports the error, but for me it was always the same line of code identified by the error message. I did not have a chance to do any experimenting to find a particular threshold number of mnu files. I may be able to find error logs. I currently sent the controller to our IT department, doing a windows XP repair, just in case there was something corrupted in the system itself.
The error was reproducible. This installation at one time must have included real-time / FPGA, because on the opening screen I ge the drop-down ring for selecting a target. If I click on this drop down ring, I get the crash on line 2770, every time. If, instead I open an empty new VI, I am able to switch to the block diagram by selecting the window directly with the mouse, but if I try to pull down on the "window" menu to do "show block diagram", I get the crash on line 2770, every time. Because the user-defined mnu files are now deleted, I would have to create them again, or find a way to reinstall them, to reproduce the error at this point.

Numbering Group G1 can be used only for one CoCd and cash journal number
Hello,
I was trying to create a cash journal when I got the error message:
"Numbering Group G1 can be used only for one CoCd and cash journal number".
Does anyone have an idea what could be wrong?
Thank you,
BolaHi,
Please check whether more than one number range is maintained in transaction code FBCJC1. If yes, please keep only one as Cash Journal has only one number range. This is the internal number range for Cash Journal.
If you want different number range for accounting documents then create new document types and assign number ranges to it.

Adding JUST ONE CELL to a table within Pages
Hello,
I would like to add +just one cell+ to a table within "Pages" - but as far as I can see the program only offers to add whole lines or columns. (Within "MS Word", you have the possibility to "add cells" in a table - you can decide whether you want to shift the other cells downward or to the right.)
Do I miss something?
Thanks for your help.
nb.Maybe I should have said: Is there a function within Pages that is equivalent to the (very useful) one within Word. There isn't, I'm afraid.
Can I adjust only the size of one cell (with the mouse, by clicking on the vertical/horizontal line) without changing the size of the whole column/line? I guess that it should be working - I didn't manage to do it - might be kind of tricky.
As I said: Thank you!
All the best,
nb. -
F4 help for only a single cell in a table
Dear All,
The requirement here is to provide input help for only a particular cell in a table.
This cannot be achieved by assigning search help to the attribute of the context as this will render all the cells of that particular column with F4 help. I tried applying the cell variant concept but only go up to a certain extent.
I tried OVS as well. But for this to work we need to lead select the entry and then go ahead with F4, which will make is inconvenient for the user.
I even searched the forum for some answers, but i could only go to a certain extent with the help of those.
So, if anyone out there has any idea, please help me out. Also, if this is a repeat post by any chance (i think not) kindly provide me with the link of the original.
Thanks and Best Regards,

How do I run a video in one cell of a table when a user clicks a button in another cell?
In other words, I want to put 3 buttons in one cell of a table so that the user can run one of three Flash videos in a cell beside the buttons. How do I do that?
Header 1
Header 2
button 1 runs video 1
button 2 runs video 2
button 3 runs video 3
video 1, 2, or 3 is inserted here when the user clicks the buttonYou will have better luck if you find a Flash Player that uses a playlist. Direct links to FLV files don't work.
http://www.wimpyplayer.com/
http://www.woosterwebdesign.com/flvplayer/
http://www.longtailvideo.com/players/jw-flv-player/
http://flowplayer.org/
Another option is to upload your videos to YouTube.com. You can customize a YouTube player and populate it with videos you specify. Then paste their player embed code into your web page.

Can you write vertically in the cell of a table, can you write vertically in the cell of a table
can you write vertically in the cell of a table, can you write vertical
If you don't understand that my response was a smiling echo of the stammering question I really can't help you.
I guess that my 36725 points prove that I may be helpful. It seems that at this time you don't really know what are helpful answers.
Using spreadsheets since more than twenty years, I know that storing something in an auxiliary object floating upon a cell isn't a serious workaround to the asked question. We may be sure that more or less soon, the object will no longer be were it was supposed to be.
At this time, if we want to put a vertical text in a cell it's safer to insert a character, a linefeed, a character, a linefeed … which, one more time is echoing the stammering question.

Changing background color in JTable, only changes one row at a time...
I'm trying to change the color of rows when the 5th column meets certain criteria. I think I'm very close, but I've hit a wall.
What's happening is the row will change color as intended when the text in the 5th column is "KEY WORD", but when I type "KEY WORD" in a different column it will set the first row back to the regular colors. I can easily see why it's doing this, everytime something is changed it rerenders every cell, and the listener only checks the cell that was just changed if it met the "KEY WORD" condition, so it sets every cell (including the previous row that still meets the condition) to the normal colors. I can't come up with a good approach to changing the color for ALL rows that meet the condition. Any help would be appreciated.
In this part of the CellRenderer:
if (isSelected)
color = Color.red;
else
color = Color.blue;
if (hasFocus)
color = Color.yellow;
//row that meets special conditions
if(row == specRow && col == specCol)
color = color.white; I was thinking an approach would be to set them to their current color except for the one that meets special conditions, but the two problems with that are I can't figure out how to getColor() from the table, and I'm not sure how I would initially set the colors.
Here's the rest of the relevant code:
public void tableChanged(TableModelEvent e)
int firstRow = e.getFirstRow();
int lastRow = e.getLastRow();
int colIndex = e.getColumn();
if(colIndex == 4)
String value = (String)centerTable.getValueAt(firstRow, colIndex);
// check for our special selection criteria
if(value.equals("KEY WORD"))
for(int j = 0; j < centerTable.getColumnCount(); j++)
CellRenderer renderer =
(CellRenderer)centerTable.getCellRenderer(firstRow, j);
renderer.setSpecialSelection(firstRow, j);
import javax.swing.table.*;
import javax.swing.*;
import java.awt.Component;
import java.awt.Color;
public class CellRenderer extends DefaultTableCellRenderer
int specRow, specCol;
public CellRenderer()
specRow = -1;
specCol = -1;
public Component getTableCellRendererComponent(JTable table,
Object value,
boolean isSelected,
boolean hasFocus,
int row, int col)
setHorizontalAlignment(JLabel.CENTER);
Color color = Color.green;
if (isSelected)
color = Color.red;
else
color = Color.blue;
if (hasFocus)
color = Color.yellow;
if(row == specRow && col == specCol)
color = color.white;
//setForeground(color);
setBackground(color);
setText((String)value);
return this;
public void setSpecialSelection(int row, int col)
specRow = row;
specCol = col;
}If I'm still stuck and more of my code is needed, I'll put together a smaller program that will isolate the problem tomorrow.That worked perfectly for what I was trying to do, but I've run into another problem. I'd like to change the row height when the conditions are met. What I discovered is that this creates an infinite loop since the resizing triggers the renderer, which resizes the row again, etc,. What would be the proper way to do this?
Here's the modified code from the program given in the link. All I did was declare the table for the class, and modify the if so I could add the "table.setRowHeight(row, 30);" line.

Make Editable only for one cell
Hi,
Is it possible to make one cell editable in a non-editable column of a matrix?
I have made a column non-editable. Now, based on a CFL value (which is in another column) selected, i want to make that row's non-editable column as editable.
My code, which fails:
If objMatrix.Columns.Item("V_1").Cells.Item(pVal.Row).Specific.value = 0 Then
objMatrix.Columns.Item("V_0").Cells.Item(pVal.Row).Specific.Enabled = True
End IfIf is column set to non editable, you cannot allow to user change the vaule in any cell. The only way is set the column as editable and catch the events as
If pVal.ItemUID = "matrix" And pVal.BeforeAction = True And pVal.EventType = SAPbouiCOM.BoEventTypes.et_VALIDATE (for cghanges, gotfocus for accesing) And pVal.ColUID = "col" And pVal.ItemChanged = True Then
which will catch the changes of cell and if the cell isnt enabled for changes, set bubleevent to true. -
Activate only one cell in the table column
Hi experts,
I am facing a problem where in i need to allow only one cell for input in the complete table.
Suppose i have 4 rows and 5 columns, and i want to allow only one field for input in the complete table based on a condition.
Can someone help me how to achieve this?
Regards,
Madhuhi madhu,
what you ca do is, have an extra attribute in the node that is bound o the table, this attribute must be bound to the read only property of the cell. so according to your condition fill the attribute with 'X' or no value so that it will be in read only or editable mode.

# You are attempting to apply a rating, color label or flag from the Metadata pane of the Inspector. Regardless of the state of the Primary Only button if you set these adjustments from the Metadata pane then only the primary selection is modified. To apply a rating, color label or flag to a selection use the keyboard shortcuts or the *Metadata-> commands*.
