Add a serious report printing tool to CVI!

Status: Under Consideration Submitted by Proven Zealot on 04-19-2013 03:35 AM 12 Comment

At present CVI is missing a serious report printing facility that permits to create flexible, professional and good looking reports.

A quick search in CVI forum shows that periodically somebody posts questions about reporting but available instruments at the moment are not satisfactory in my experience.

 

As far as I can tell, a good reporting instrument:

 

  1. Should integrate easily with CVI
  2. Should be fully documented, with some example for the more typical types of reports (text + table, text + graph, text + image...)
  3. Should not rely on external programs (some customers have rigid constraints on the software installed on equipment machines; additionally, asking them to have full Word or Excel or Diadem installed only for reporting is just not serious)
  4. Should not rely on ActiveX controls to be licensed separately (same as above)
  5. Should permit to include text and graphics (images, graphs...) and define headers, footers, page numbering and other common features normally present in reports
  6. Should output data directly to the printer or in PDF format
  7. Should have a preview facility both for development and for the user (something that NIReports hasn't and will never have)

Improved/Accelerated Graphic Performance

Status: Under Consideration Submitted by Member on 02-15-2011 04:56 PM 6 Comment

We have recently dropped CVI (as of 2009) as an option for use with our many data visualization applications.  The graphic performance is just too slow and clunky to put up with any longer and gets worse as we add features or try to make 'native looking' applications (that resize, animate, etc).  

 

Things like dragging/updating cursors is noticably clunky when you have more than one graph updating (linked cursors across more than one graph).  

 

Updating datasets in large tables is slow enough to watch it step through the rows.  Even using suggest tips like using ATTR_CTRL_VAL instead of SetTableCellVal, when a large table has to update... it's painfully noticeable. Basically any operation that updates a large portion of the UI.

 

Another example, try to resize and move controls (as most other applications do) on the EVENT_PANEL_SIZING?

 

I'm going to go out on a limb and guess that CVI doesn't use any graphics card acceleration? since workstation or netbook doesn't seem to make much difference in graphic performance.  

 

Our clients notice when our applications look 'clunky' and 'slow' when compared to smooth, responsive apps/interfaces from competitors.  It's often the little things that make a big difference in appearance.

Save panels as uir when the panel is dynamically generated

Status: Under Consideration Submitted by Member on 05-22-2012 08:10 AM 1 Comment

Hi,

 

I think it would be a nice tool to save a panel which is generated dynamically from a source code. If I have a database with many variables which I want to set on a panel as controls, I could write an import of this database, generate a panel automatically and could save this panel as UIR file. After this I could use this automatically generated UIR file in a project.

Add SetTableCellRangeAttributes to improve performance in the same way like SetTableCellRangeVals

Status: Under Consideration Submitted by Member on 02-21-2012 02:49 AM 4 Comment

Using SetTableCellRangeVals to update several thousands table cells is very effective.(better than using ATTR_CTRL_VAL)

I miss similar function for set atribute values in the same way. In example:i need  to set text to be bold or  set background color for each table cell separately.

Ithik that usability of SetTableCellRangeVals will be better if SetTableCellRangeAttributes will be avivaible because there will be the same program approach/logic for values and attributes,instead of mixing multiple cell vallue update and one by one cell attribute update.

Binomial Coefficients (a,b)

Status: Under Consideration Submitted by Trusted Enthusiast on 10-19-2010 02:38 AM 1 Comment

In the Advanced Analysis Library I'd like to see a function for efficiently computing binomial coefficients. The 'standard' definition

 

a! / ( b! * ( a - b )! )

 

is not efficient and susceptible to overflow. A better approach for example could be the calculation of ln (n!) using the gamma function as outlined in Numerical Recipes.
