    TreeView->AddObject

    I am working with the C++ Builder example on how to add objects to a TreeView. I have written code to add nodes to a tree, now I would like to expand this to add a structure as each node (so that I can store integer values as part of each node) I worked through the example code, created a...

    DB use

    Danny, I too had problems when I started out with Database programming in BCB, but it gets easier once you've seen a few examples. Try the following link - you should find all the info you need there http://www.thebits.org/tutorials/dbase.asp Regards, Andy

    I have a project written in BCB5 that i need to integrate into an older project written in BCB4 When i try to open my BCB5 project, I get a "Project Rule not found error" and the project won't open. Why does this error occur? Does this mean I have to write out my code from scratch in...

    DLL of a form & components...

    I've written a BCB project that displays a window and a webcam component and allows me to capture a frame from the webcam and save it as a memory stream. I need to write a .DLL that will show the form and perform the frame grab so I can pass the stream of data into Labview or Matlab. How can I...

    Time-Stamping??

    I have a ttreeview that is populated from a database. Once the treeview is populated, I can save it's contents to a file and in future load the treeview contents from that file (as long as the database hasn't been updated in the meantime) as it is faster than redrawing the tree from the database...

    Copying a list of files

    Wim, Thanks for the advice. I had already tried to use CopyFile and found that it didn't work. Having gone back to it I found that it wasn't working because I was specifying my target directory as "C:\temp\test\" not as "C:\\temp\\test" Having made the change it works...

    Copying a list of files

    An example would be good thank-you. I found a function called "CopyFile" that looked as though it would work for me, but when I implement it in my code, the files are not copied to the directory. Are there any other routines like "copyfile" out there?

    Copying a list of files

    I have a list of filenames (and paths) that I need to copy from one folder to another. I've set up a for-loop to go through all files but I can't find a filecopy procedure that seems to work? Can anyone help with this? Specifically, which libraries I need to include etc Thanks
