Feature extraction is kind of a broad topic! What types of extraction do you need to do? Thresholding? Edge detection? A good place to start looking is http://www.mathtools.net/C++/Image_Processing/index.html You might also want to check out the Intel Image Processing Library - that provides...

Solved problem - needed to add a "new" call inside the loop to create a new instance of my structure on each iteration of the loop

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...

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 header file that is used by a DLL and also by a GUI program The header contains a typedef that I need to change from INT32 to something else (as our new code already has INT32 defined as something else) When I change the defenition to myINT32 in the header file, and change all...

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...

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...

I have an urgent requirement to develop a GUI to display the output from a web-camera, and capture a frame from the camera and convert to data stream for sending to a client program running on the same network. Does anyone have any info on where to look for components to access the USB webcam...

i have a set of strings "C:\test\abc\file1.dat" "C:\test\test2\test3\file1.dat" and I need to turn it into a filename - "test_abc.dat" "test_test2_test3.dat" I have written code to produce the output required, but it doesn't remove the filename from...

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...

Following earlier posts, I have written some code to take records from a database and populate a treeview from those records. However, the code is not working 100% correctly and I am having trouble pinning down the problem I have included 2 tree diagrams - TREE OUT shows the tree my code...

Here's my code so far ------------------------------------------------------- void __fastcall TForm1::Button1Click(TObject *Sender) { //--------------------------------------------------------- // Variable Declarations //---------------------------------------------------------...

I am having big problems with a TreeView component in C++Builder. Basically I have a database table and I am trying to populate a tree based on the contents of the table. I take a directory string from the table, split it up, and then make nodes out of each of the strings, so...

I have a database table that holds file information (filename, filetype, directory etc) and on running my application I want to populate a treeview object to allow users to select files based on which directory they are in. (In other words, filenames are shown as leaves wheras the different...

I need to read in bitmaps and png files as binary data, change the header data by overwriting the first 20 bytes, then write out the data to a new filename. I have written code to do this in matlab (shown below) but for some reason I am having a complete block on how to do this in C++ Any help...

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...

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?

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
