Programming :: Generating Excel Charts From C?

Feb 24, 2011

how to generate excel charts from C, or if it's possible at all? For example, if I had 2 arrays that I wanted to export to excel and graph against each other. I know how to export it to a csv file, that's no problem, but I have no idea where to start with generating a graph of the data. I can't seem to find any examples anywhere. Just a simple example to show you what I mean: Code:

char arr1[] = {'a','b','c'};
int arr2[] = {10,20,30};
int main ()

Programming :: Making Existing MS Excel App Web Based

Jun 7, 2010

I have a LAMP based web hosting account (BlueHost). I have an existing simple MS Excel application which I would like to make it web based. However I am not sure what tools or features of PHP are out there that will aid me with this task. Here are some details:

1. I don't want to create an entire Excel program online. For that there are plenty of existing applications like Google Docs, MS's own online version of Excel, etc.
2. My current excel file uses some of the following excel functions:
a) SUM
b) Product Sum
c) Conditional Formatting (like changing font color if an amount is below a threshold, etc.)
d) Sorting (Date, Amount)
e) Drop Down Box to select pre-defined values

3. Ability to add/delete/modify a entry (row)
4. I don't care whether the application has the same look-n-feel as MS Excel.

As you can see it is a very simple home grown excel application with few basic mathematical functions. Here are some few thoughts that I have currently in my mind:

i) Just start coding intuitively as you would develop a normal web based application.
ii) Do (i) but use some of the PHP's excel oriented helper functions (COMs?) if there are any
iii) Use completely a different set of tools permitting that they run on LAMP environment.

I could have started with (i) but before making a costly mistake I thought I would get some opinion from the community to see if this is the right approach.

Programming :: Code For Generating A Pop-Up Window In C

Aug 4, 2010

Unfortunatelly since i have no background at all about GUI programming, i dont know even the keyword for that i want to generate a pop up window from my program (written in C) which show a message and an OK button. in my opinion, maybe i should use directly the Xlib library and not the GTK or QT library for example so the program can work almost on every linux system. A code snippet/hint for the pop-up window then?

Programming :: Generating Timer Interrupts In C?

Jul 23, 2010

I'm trying to understand how interrupts work. Is there a way to generate timer interrupts in C. Also can we enter into the protected mode of the CPU. Does OS (specifically, linux) place any restrictions on user programs entering protected mode. If it does not, do we just have an assembly language program which changed the mode, followed by the C code... I'm just trying to understand how things work at the lowest level. So I'm trying to write few snippets to test my understanding.

Programming :: Generating Makefile Ans Configure Script ?

May 17, 2011

I know how to manually writing a makefile for my project, but I am new in using makefile & configure file generation tools like automake to generate a makefile and a configure script file.

I had done research on tutorials for generating makefile and configure script file.

I know that I need to manually write two files (makefile.am and configure.in).

I use wxWidgets GUI library, libconfig library, and libpcap library to do my project.

wx-config is a tool that can return the library files and include directory for wxWidgets library.

When using g++ to compile my files, I need to add in this line "`/wxlib/bin/wx-config --version=2.9 --static=yes --unicode=yes --debug=yes --libs`"

How to add that line to the makefile.am file?

Programming :: VBA / Excel - Looping Through Image Controls Based On Cell Contents?

Jun 28, 2011

I have an Excel Spreadsheet which reports upon weekly performance. One portion of the worksheet looks at week over week increases /decreases. I've placed a number of image controls (15 in Total) next to cells which calculate week over week change. The image controls simply display an image depending on whether the value of the adjacent cell is positive or negative. So, here is my basic working IF statement:

Code:

Private Sub Worksheet_Change(ByVal UpDown As Range)
If Range("J26") > 0 And IsNumeric(Range("J26").Value) Then
Image1.Picture = LoadPicture("C:path oup_arrow.gif")
ElseIf Range("J26") < 0 And IsNumeric(Range("J26").Value) Then

[code]....

As you can see, this is pretty simple. What I'd like to do is find a way to loop through all 15 controls and avoid having 15 IF statements run on the Worksheet_Change() event. The cells containing the week over week values are all in the same column, but not continuous. Involved cells are: ("J26", "J27", "J33", "J34", "J35", "J36", "J37", "J38", "J39", "J40", "J42", "J43", "J44", "J45", "J46")

Programming :: AMD CPU Generating Way More System Load Than Intel Xeon CPU?

Oct 11, 2010

I am running some muti-threaded code that uses a lot of memory (~6GB). I have it compiled on a cluster that uses Xeon 5160 quad core CPUs with 4MB cache/core, 8GB of RAM and kernel 2.6.18 (x86_64) and I have also the same code compiled on another cluster that uses Opteron 2214 quad core CPUs with 1MB cache/core, 8GB of RAM and kernel 2.6.28 (x86_64). On the Intel cluster the code generates barely any system load when I look on top but on the AMD cluster it can generate over 50% of system load. On the intel machines my process can generate a constant load of 3, while the load generated by the process on the AMD machines is about 1.6.

Does anybody know what could cause this? Could it be the version of the kernel or the difference between the CPUs (for example, the much smaller cache of the AMD CPUS)? My software and all its dependencies are the same on both clusters. I am also using the exact same version of GCC to compile everything.

Programming :: Bash: Generating A Random LETTERS Sequence?

May 12, 2011

I tried googling around but i cant find anything related to this: everyone seems just interested in random numbers, so when it comes to random letters there is a lack of informations. However, i am trying to figure out a wait to get a random letters string that matches a simple rule: it must be a sequence of consonant+vowel. So for example, these are some 6 letters strings i would like to obtain: wolupa, tafoke, zewevu, cupimo.

Programming :: Generating Files With Different Names At Each Loop In Fortran?

Nov 7, 2010

I am trying to write a loop to open four main-data-files. At each open of the main-data-file, I want the loop to open another four sub-files and split the data from the mail-data-file according to the creteria and dump into the four files. When the loop goes to the second main-data-file, it shall generate another 4 sub-files with different file name. And the process goes on. That means I will have total of 16 sub files for the four main-data-files. Each four files from the 16 files shall have specific name on it. Based on the code which I given below, I would say when the file at UNIT=100 is opened, 4 new files needed to be opened as well. They are:

maximum_dist_001_064.dat
maximum_dist_065_128.dat
maximum_dist_129_192.dat
maximum_dist_193_256.dat

Ubuntu :: Office Software - Superscripts In Charts?

Jun 17, 2011

In the fall when I return to my full time studies in university, I would like it very much to use Ubuntu as my operating system on my main work computer, since it runs clean, fast, and stable.

However, the only thing that would stop me from doing this is some good office software. OpenOffice, Libreoffice, Koffice, etc all look nice, however I can't find a way in any of them to generate a chart with superscripted text on an axis title. I've even tried microsoft office web apps and google docs. If anyone knows a solution to my problem that would be amazing

Ubuntu :: Open Office Writer - Page Moves Around When Working With Graphics / Charts?

Mar 16, 2010

I am using OO 3.1 on Karmic 9.10. When working with Open Office Writer and either graphics or charts, a couple of things happen. First of all, the page position moves around. For example, if I click on a graphic I have inserted or on a chart, the page on my screen may shift up or down by a half inch or so. If I click back out in a text area, the page moves back to where it was. This is very annoying. Has anyone else had a problem like this? I have tried turning off compiz completely but it doesn't fix it
