Very basic example of creating a user control. This one has actually turned out to be useful in an application I wrote. I kept the features to a minimum in this one so that it would be easier to see how it works.
This form can be used as a template for creating dynamic "Outlook" style forms in VB. Each frame resizes independently...and best of all, NO OCX!
Explains the usage of boolean logic in Visual Basic to evaluate complex operations in the terms of "Boolean Logic Gates" ...a concept any electronics techies out there will love.
Makes it easy to perform a clean "Shell & Wait" where your applicatoin kicks off an external application and waits for it to return before continuing. Many shell & wait examples I have found tend to overdrive the proccessor in a loop or require you to make API calls. This one uses the Windows Script object to take advantage of it's built-in wait parameter on the .Run method...scripting's version of Shell.
Lists all of the files in a directory matching the pattern entered in the form.
Explains how to create your own custom variable packages that store various data types in one variable and display the elements in the IDE drop-down list while coding. This is a seldom used but very powerful data type in Visual Basic.
Explains the concepts of Subs, Functions, and Parameters. If you are a little fuzzy on the difference, take a look.
Newest in the series aimed at teaching newbies (and not so newbies) about the commands that VB has available. This edition gives a basic outline of DateDiff() usage and, as always, some copt-and-paste sample code.
04/28/2001 - Describes the usage of the Choose() function; A really neat but seldom used command in VB.
To show the usage of the Chr() function.
Explains how to use the Visual Basic DateAdd() function to add and subtract dates.
Explains how to use the DatePart Function in Visual Basic.
Automatically rescales a form to keep the layout identical at any size. For those of you out there who lock your forms to a certain size because rescaling is such a pain, give this a try...you will love it! NOTE: Although this code works as is, it is JUST AN EXAMPLE. You should be able to take the same logic and apply it to all of your forms, but please note that this example does not handle every type of control. For special controls (dbGrid, etc.) you will have to write a little code yourself to make it work.
Amazingly easy method for editing flex-grids in place. This is an example that I created to help someone out who needed to edit a flex-grid in place and didn't want to get a third party grid. It is a good starting point for a custom grid control. Good, bad or ugly, comments are always welcome. M@
Explains the basics of using the App Object.
Explains the basics of using the Dir() command to get file and folder information.
Ever wonder how to create your own custom list of parameters for one of your functions? You know, like the MsgBox options list with items like vbQuestion, vbExclamation, etc? This article shows you how. It is easier than you might think.
Explains the basics of using collections in Visual Basic. These are a very powerful and often unused feature of VB.
Demonstrates one method of creating custom menus that can contain images, combo boxes, or any other Windows control. Although this is not the most powerful method, it doesn't require any API custom calls or any third party .ocx's (like the Office Toolbar). NOTE: This is a DEMO project. It is not a finished product. I realize that it has some pretty big limitations as it is, but it should be enough to get someone who needs to add VB controls to menus a good start. I made it simple to make it easy to understand. Please feel free to use it, modify it, and call it your own...but please don't tell me things like "It would be better if it had a calendar control" or something like that. Instead, modify it to include a date-picker, calendar control, or whatever and re-post it as an improvement. I am sure others would appreciate that and I sure won't mind.
*REPOST* Sorry all...I left out a form file. This one should be good... Completely formats source code text...(adds white space, blocks). Fully customizable...add new commands, change formatting preferences, etc. Currently set up for VB, but can easily be customized to any language. This is a port from an add-in I wrote last year. Someone was asking about some code that did this that Ulli took off of PSC when he got mad and left. I never saw his code (probably better than mine) but since I had it, I decided to post it. This works surprisingly well. NOTE: This project is for DEMONSTRATION. It is a quick port from a VB add-in. Therfore, it may have some bugs...but I don't know of any.
