Hi,
I am writing few programs which generate some data that needs to be plotted. I am currently using MS EXCEL to plot the graphs. I would like to know if there is a way to call the EXCEL application from C++ programs and make them generate the plots. I heard that using DLLs and Marcos its possible I dont know much about it. so can anyone help me.... pls
I am a new to this subject and any kind of help would be very much appreciated

Hi Jyothi,
I am not quite sure about excel, but I know that it is possible to control word and outlook from a C++ program, using what is called "office automation". In the directory where the Excel executable is stored, you should look for a file called "Excel9.olb" If you can find this, then you can import it in your Studio environment, which will give you all the functions you need to control excel. You will need to look for descriptions of the necessary functions on the inetrnet. Microsoft does have a number of usefull documents, but these are usually hard to find!
Good luck.

Can you simply generate a text file that contains the data numbers in ASCII format, saving it with the XLS extension and then open it with excell (also programmatically using ShellExecute)and then plot that data manually?
Or you need to prepare the graphs automatically?

Hi Russell,
Thanks for the reply. Its sound easy but I want my C++ program to open the excel application and plot it when I run my C++ program.

This is rough idea , you can create some addin Excel , and you can invoke it from your application . I think there is a way here.
Or one morething , when u invoke excel from c++ , you can specify macro file name to that.. so excel can open that macro . Then inside that macro u can do some stuffs.. (i am not an expert in macros. i don't know whether ur task is possible from macro or not)
If u can Dream... U can do it

If you need automatic plot you can choose one of:
1) learn xls format and save directly the data with tha graps
2) Use a different (and easyer) file format like CVS compatible with excell that leave you prepare grapsh
3) Use Macros in excell;)
4) Find a different (freeware if possible) program that leave you write a data file (easily) and set there the params to plot they
5) Prepare your drawing class (here there is an example: http://www.codeproject.com/miscctrl/graph2d.asp[^] )

It's success when I build a driver program in Win32 Free mode, but it's error in Win32 Checked mode, and report this error message 'Matching PDB file not found', I looked for the reason in google and can't find it. would you help me???
I like nature and smile ^_^

A .pdb file is Microsoft compiler specific mostly. It contains debugging information for individual obj files [rather than in obj itself]. Therefore, you need to do a rebuild when you move to a different compiler or platform.

Thank you, swati24n but I have rebuild more than 10 times, there are the same result. by the way, following are error message:
Generating Code...
Linking with DDK linker...

(C) Compuware Corporation, 1996-2004
MODULE=.\objchk\i386\test.sys

Error translating D:\test.sys: Matching PDB file not found.
Error executing d:\windows\system32\cmd.exe.

Not sure. Do you by any chance have the .DBG and .PDB in the same directory? It looks like the linker for the project is looking for the PDB generated for the module test.sys and cannot load it because test.sys is not built with the same compiler perhaps?
You can alway build your code without generating a PDB. Every compiler has a flag to do this.

There is test.pdb in the same directory(objchk\i386), when I disabled the pdb flag and the error continuing. I don't known how to solve it and it make me crazy

Well, I did my first lexical analysis (LANA) package in 1st year college as a "beginner" though even as a beginner I had about 3 years of programming already. I should rewrite it someday. maybe with a nice android body attached... hmmmm....
