I don't know if this fits your problem or not, but remember that there may be two data structures using the Clientdataset. USing Update is different than ApplyUpdates. Google Cary Jensen who did a series of articles on Cleintdataset behavior. ( I believe it was at delphi.About.com)

Look for the OnMouseMove event on the form or compnent that is receiveing the mouse messages. Place your popup menu code to trigger on the onmouse move event. You should be able to access and enter code for this directly through the object inspector window events page.

I also use BD2006. Another area I have struggled with in the IDE is the "Uses" statement. I have had numerous problems where errors are listed that the IDE cannot find files in the uses clause such as Classes or Sysutils and yet the paths are included in the options library paths. The IDE hold...

IF the file is visible from each location through your server, it should be accessible from each. The connection string may differ between locations depending upon how it is defined for access at other locations. Your network manager should be able to give you specific requirements to alter the...

I also discovered the "Absolute" keyword that allows the declaration of two variable types overlapping in memory. Var data array of byte; Int : Integer absolute data; aligns the data and int in memory.

Sggaunt, How do you get an integer or float into the data array of byte to begin with?

I may halve answered my question. I forgot that o character in shortstring sets length of the string and thought it was terminated by CR and/or LF. That would mean that my data could be truncated if those characters occured in the data string. Thanks for your snippet. I assume that Data is...

I am working on a project for a Cad program in which I must embed data in the Cad file. The tools for doing so in the cad program allow for embedding boolean, integer, double byte and string values, one at a time. There is a lot of data and the best way to store it would be in a single packet...

Yes, Handle it just as you would any other character.
