Reading measurement file correctly

[Seessami]

I have a problem about reading a file. The file contains measurement results of a highpassfilter. I have tried to read the file but the measurement is displayed incorrectly.

I have attached the binary file and a jpeg of the filter.

Thanks in advance!

Hi Seessami,

which format has your file and how do you read it?

Hi mike,

I'm pretty sure it's a binary file. I have tried to read it as a binary file but it's not displayed correctly. My task is to update an application. The previous application has been made with visual basic i think, and i'm making a new version with LabVIEW. This new application has to read/write the measurement data in the same format as in the previous application.

Hi Seessami,

how do you read your data? Only to know it´s a binary file is not enough, you have to know the format of your file. How do you write the file?

Hi seesami,
                   What format is .cal? Have you used read to spread sheet function before?

Hi Mike,

I don't know how the current application reads/writes the data because I don't have the source code of the application. But I will find out the file format of the measurement..

I finally found out the file format. It has also other information besides the actual measurement data. Now I need to read the file. How can I unbundle all the data from the file? All the headers separately and the data itself?

Hi Seessami,

you can read your file with the Excel ActiveX functions. See this thread for some information about it.

I can read the data now

Now I have a problem in writing the file. I have made a vi that reads the data and I've inserted the write data vi as a subvi. The data seem not to be written in the same way. So what could be the problem in my write binary file_oma.vi?

Thanks again!
