    <p>My program has several paths to be watched, such as<br/> C:\XML<br/> C:\MyProg\Raw<br/> C:\MyProg\Subset\MTSAT<br/> C:\MyProg\Subset\GOESW<br/> D:\Dataset\Composite<br/> D:\Dataset\Global<br/> E:\Dataset\Mosaic<br/></p> <p>I want to add 4 paths, namely C:\XML, C:\MyProg, D:\Dataset and E:\Dataset, to my CFolderWatch class instance for the purpose of folder watching insetad of all 7 above-mentioned paths as long as its "Include Subdirectory" switch is set to TRUE. Suppose all paths of being watched have been added to a vector container. </p> <p>Therefore, my question is: How can I find the "least common part" among the paths on the same logical drive? Thank you in advance!</p> <p>Detailed explanation to my question: 1. I got some user-defined directories. 2. I want to these directories to be watched. 3. Before watching, I want to do some preparatory job, for example, find the common part among the path(s) on the same logical drive to avoid possibly adding so many paths to my watching class. For instance, if there are 3 paths on the logical drive C: as follows: C:\test\Data\R1, C:\test\Data\R2, and C:\test\Data\R3, the common path is "C:\test\Data". So, we should add "C:\test\Data" to the watching module, not the three paths. What I mean the common path here is that it has at least one level of directory. If one path has no common path with the others, just returns unchanged. 4. First thing first, the algorithm should handle different logical drive(s). That is to say, all paths must be classified on the basis of their respective drive letter. Then, find the common path among the passed paths on the same logical drive letter. </p>

    3. CO@JB: "least common paths" don't include the case of "logical drive letter" only. for example, "C:\MyProg" is the least common part among the three paths such as C:\MyProg\Raw, C:\MyProg\Subset\MTSAT and C:\MyProg\Subset\GOESW on the same logical drive letter "C:\".

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
