How do I save an ERD in Toad for Oracle as a .txp file or any other format that I can open in Toad Data Modeler?
I have tried to find a way to open the .erx files I have in TDM but it doesn't work that way.
Thank you
I have been looking for a way to do this for a very long time (about a year now) and it would appear that it just cannot happen.
No need to save it differently if you are using version 6.4. Simply select the Import from the File menu and Reverse Engineering wizard will take it from there.

How can I find the data source of my report? I recently changed laptops and moved my report to the new laptop, but I forgot the data source for my report. I used my database as a data source but because I am not sure on the path of the data source I can not refresh my dataset. Please help.
Other than the method mentioned by #mkRabbani using the Advanced editor, the simplest way is to
click on the "Gear" icon beside the Source Step
and it will open a pop-up using which you can identify the existing source and also replace the source to a different one.
Please note that this applies to all data source, not just excel (but with their own customizations)
If you are looking for the folder location of your data files, go to Power Query Editor and right click on the table you wants to know the source. Then click the Advance editor option and you will get the source as shown below-
I'm using Stata 11 on OSX, new to Stata. Someone has sent me a .do file and I want to amend it and run it.
If I open the file in Stata (using File > Open), I see the file appear like this:
I can click on text, but I don't seem to be able to edit or select it. It's almost like an image rather than a text file.
So, um, how do I edit the text?
All of my Googling suggests I need to use the "do-file editor" - I'm not sure if this is it, and if so, how I set it to edit mode!
Open a new .do file (ctrl+9). Then in that go file>open and open the .do file in the editor. That should do the trick.
I want to use some of the datasets available at the website of the Weka to perform some
experiments with Neural Networks.
What do I have to do to read the data?
I downloaded the datasets and they were saved as .arff.txt so I deleted the extension of .txt to have only .arff. So I used this file as an ipnut but an error occurs.
Which is the right way to read data?
Do I have to write code?
Please help me.
Thank you
I'm using Weka 3.6.6 and coc81.arff opens just fine. You are using Weka 3.7.x, which is the development branch of Weka. I suggest that you download 3.6.6 or 3.6.7 (the latest stable release) and try to open the file again.
There is also another simple throw...
open your dataset file in excel in my case MS Excel2010, format fields intype.
and save as 'csv',
then reload that csv file in the weka explorer and save on the local drive as arff format.
may be this help.
How can i make user to downlaoad a excel from the django app.i HAVE A MODEL WHICH gives the report.Now i want a option from user can download the file in excel form.ANy Solution
You can output the data as .csv which is easily imported into MS Excel.
http://docs.djangoproject.com/en/dev/howto/outputting-csv/
EDIT
After I wrote that I got curious if there actually was some way to do it directly to excel format and found:
http://www.python-excel.org/
That made me wonder why you didn't google your question before posted it here.....
I'm not sure quite what you're asking. If you're asking how can you generate output that's able to be read into Excel, IMO your best bet is using a CSV (see amoeba's response) as that's pretty generic. There are ways of using true Excel formats as well.
I'm thinking though that perhaps you're asking how you can have a user click a link (or whatever) and have Excel pop up with your data in it? (IOW, you've already generated the output).
I suppose I'd say a few things:
1) It shouldn't be specific to Excel, many users use things like OO.o (thus my CSV suggestion)
2) It's going to vary depending on their browser and how they have it set up. Personally, I don't like pages opening up the "proper application" so I turn all of that off - other people enable it.
I have a small Win32 console application which is essentially a test harness. I read data in, do some processing on it and currently just output some of the numbers to the console. This isn't a huge problem - I can get an idea of what the data looks like, but it would be much easier to analyse if there was a way of getting that information into a graph for each run of the software.
I've been getting to grips with GNUPlot recently, but can't work out a simple way to get the data sent to it. Has anyone tried this? ..or is there another graphing application I should try?
Excel and OO Calc are great tools and I've loaded .csv data into them for graphing data plenty of times myself. I was, however, hoping for a way to dynamically pipe data into a graphing application to avoid having to close/reopen excel and plot a graph each time I want to look at some data.
I think you can pipe data into GNUPlot (which is why I mentioned it) but the details of how to do so are rather scant.
A simple approach is to wtite the data out as CSV and then import it into a spreadsheet like Excel or OpenOffice to do the graph drawing.
Edit: Following your question, I got interested in GNUPlot myself - this is the simplest description of using it from the command line that I found: http://www.goldb.org/goldblog/CommentView,guid,f378e279-eaa5-4d85-b7d2-0339a7c72864.aspx
Never underestimate the power of Excel and a .csv data dump.
Writing data to a .csv file form C++ is not very difficult and there's lots of articles out there regarding the subject, for example: here, or just google.
Excel can easily load .csv's and then you can just use that to plot whatever graphs you require. THis is particularly useful if you just want a quick visual sanity check of results etc.
You don't really need to touch VBA to do this
In Excel you can set up a Data Connection to a file, it supports many files type but CSV does work fine.
Go to List item
Data Tab
Click Connections
Click Add
select the file
go to the connection properties - un-tick prompt for file name
set the required period.
close the connections dialog
select the start cell for importing the data - cell 1a on worksheet 2
click existing connections
select you data connection
flip to worksheet1 add your chart and hookup the data.
the chart will now update automatically
this is Excel 2007 - but think older version had this and I think OO can do it to.
You might also want to look into XMGrace which allows you to launch it and drive it dircetly from C/Fortran programs as shown here
Excel is completely script-able. Use the macro recorder to figure out the steps. Create the chart in its own sheet. Then save the chart using the GIF filter.
The actual import is something like:
ActiveChart.Export FileName:=something_dot_gif, FilterName:="GIF"
I just found an example of piping data into gnuplot on Cardiff University's website. Not tried it yet, but it looks promising!
[edit] ..and another which includes some notes for windows.
You can use MathGL - it can create a window (FLTK, GLUT or Qt) and display plot inside. Also it have large set of plot types and can work in console.
