DB/Reporting :: Lost On Dynamic Arrays - How To Fill & Check

Jun 10, 2009

I guess I'm the newbie. I've just started trying to learn Visual basic 2008 express edition. I'm an old cobol mainframer and I'm having a hard time understanding this language. My project is to read a log file looking for claim numbers and I need to check that each claim has a start record and an end record. I need to fill up a dynamic array because I don't know how many claims there will be. The array needs to hold a unique claim#, a start claim flag, an end claim flag.

Control Arrays - Fill Array With A Loop

Jun 17, 2009

I am trying to port a program I wrote with old VB 1 and I have many control arrays in the program, and it was so easy to do this in older versions of VB, now I am trying to find how to do this and all the answers I have found are a major productions, to replace something that was so easy to do? I would think that microsoft would make programming easer with each new incarnation. instead they are making it harder. doing away with the DATA and READ statement, now it is much harder to fill an array with a loop, now you have to enter each item in an array ONE by ONE. they did away with the ON statement, I had several ON statements, I had to make complex Select case constructs. to replace a simple one word statement?

To make an array of controls in OldVB all you had to do is Name a Second control the Same as the First, and a dialog pops up and ask if you want to make an array, you click Yes, and that's it, what could be easier than this?

Bitmap Array With Dynamic Contents

Apr 2, 2010

I'm working on a program that has to get a set of images and then scan them to find pixels that match colors in an color array. Anyway I think I got everything working but how to load the images in as bitmaps. See the images are dynamic, they change there filenames so I can't call them with a static call like Dim bmp2 As New Bitmap("c:button.gif").

So I am using a loop to feed the images into an array for bitmap but thats not working, anyway that I can do this as, right now the program gets all the filenames for the images from a text file that is sent in to us. All I need to do is have the program check each image for pixels that match our color list. But I cant get the images into the bitmap array.

Dynamic Array Of Byte Arrays?

Jun 24, 2009

A project requires to allocate a varying number of byte arrays (buffers).

It would be ideal if the following definition would be possible:

Dim ArrayOfBuffers() as buffer(10000) as Byte

The byte arrays must be ordered sequentially because they have to be written to a file by efficient procedures destinationFile.Write(ArrayOfBuffer(3),1000,1000)

The number of buffers will change during program execution sometimes. Therefore it would be nice to be able to do a ReDim on the data structure when needed.
