Have you ever needed to read a fixed length text file in Visual Basic? I have written quite a lot of applications where I will receive a fixed length text file from the mainframe. Tired of using the Left$, Right$ and Mid$ functions to parse each line for the individual elements of the line? Then read on. Oh, and thanks to Rockford Lhotka's, book on Visual Basic 6 Business Objects for giving me this idea.

Here is a useful function I created to solve a problem I was having in processing files for one of my applications. This function works better than trying to use the VB 'OPEN' command because it will always return the correct state of the file (even on a file that is being FTP'd at the time of the test.) See remarks in the FileReady function on it's use, as well as a sample at the end of this note.

Checks to see if a file exists.

This may be some help if you want to print with VB. It does not cover everything to do with printing but is a good start.(...No PrintForm...) Using X,Y, Coordinates.

Want to put an .ini file INSIDE your .exe file? Yep...it's another file attachment sample. I've commented it heavily for newbies. There are only 2 subs, very short and to the point. It should help get you off the ground if you've never done this before.

In All the other methods I've tried, I run into a barrier(around 170K+) where loading a file suddenly becomes very slow. I've tried many methods found here and in books, and none have proven to work as well as I was looking for. After a long search I ended up spending some off-time figuring a way out myself. This is what I came up with.(speed increases from 20 seconds@170k to .4 seconds@170k)

This code will count all of the lines in a text File. This code will work on any sized file, and is quicker than using LineInput or the FSO.

Lets you create A windows cabinet file (.cab) containing any file(s) of YOUR choice. Since a cabinet file is something windows uses. Once you make it, you can give it to anyone and they can open/extract it without special files. PLEASE vote and/or leave feedback/comments on what you think.

There are many methods you can use to return certain parts of a fully qualified path to a file. Here is the SHORTEST and FASTEST way to 1) return just the path, 2) return just the filename, and 3) change the extension of a filename. The code is so short that it is probably faster to keep it inline than to create additional functions. (I've done so here to better illustrate the parameters.

This project demonstrates how to extract large and small icons associated with files into an imagelist and displaying them in a listview with the filenames. The SHGetFileInfo function of the shell32.dll library is used, which makes the job much easier than before. The ImageList_Draw function in comctl32.dll is used to draw the icon in a picture box,from where it is placed into the image list. Other submissions on PSC do an OK job on large icons, but the small icons are a mess. Not here! Credits to Peter Meier for his DelRecent posting.

Project includes a very simple Class Module to talk to Excel with a demo project showing how to export the contents of a ListView to a workbook, and then create a pivot table from it along with page setup. The class module is pretty basic but I hope it helps some with ideas of how they can now add Export to Excel options to some of their projects. NOTE: The end user must have at least Excel 97 installed for this to work. KEYWORDS: EXCEL OBJECT CLASS WORKSHEET WORKBOOK PIVOT TABLE
