Visual Basic Source Code for FREE Site - MY New Website with many articles, source code snippets, question and answers and more for ALL VB's.

• April 21st 08 - A new example for VB.NET 2005 and Visual Basic 2008 has been added that shows how to create a simple image or picture viewer and features a basic slideshow feature. The slide show will go through the list of images while having a simple pause before each image changes. There is a audio sound or music feature as well if you want to play a audio file while the slideshow is running. The example shows how to use a sortedlist with a key and value related to that key to hold the entire path of the image but making it so the user will only see the filename instead of having to see the entire path with the filename. There are basic picture/image Left and Right rotation features as well. Located in the VB.NET 2005/2008 - Examples page near the bottom of the page.

• April 8th 08 - A new example for Visual Basic 6.0 has been added that simply shows a couple ways on how to check if a file or a directory or folder exists at the specified path or not. It uses the Dir function and the FileSystemObject in the Windows Script Host Object Model to do the checking. Located in the VB 5.0 and VB 6.0 - Examples page.

• April 6th 08 - There were two new examples added to the site. One is for Classic VB and the other is for VB.NET. They are both on how to hide or show the caret (blinking cursor) for a textbox and combobox control using the HideCaret and ShowCaret API calls. Remember that the control whose caret you want to hide/show Must be the owner of the caret at the time of calling these APIs. Also when the control loses ownership of the caret it will reset the caret and you will have to call the HideCaret API call again. But if you want the caret (blinking, flashing; cursor or whatever you want to call it) to stay hidden try putting the HideCaret code in the controls GotFocus event. Which whenever the control gets focus, it will hide the caret from the user even if another control temorary gets ownership.

• March 24th 08 - Another example for VB.NET was added as well. This example uses the LinkLabel control to mimick a real webpage link. The control will look and act like a common link on a webpage. When the link is clicked, it will open the default webbrowser application and load the address specified in the LinkData property of the control. Compatible with all .NET VBs including Visual Basic 2005 and 2008.

• March 24th 08 - A new example for VB.NET has been added named Ultimate Textbox Manipulating. As the name entails it shows how to do Many things with the standard textbox control. Some of the codes are: searching, selecting text, page right/left, line right/left, page up/down, line up/down, getting line and character information, along with cut/copy/paste and adding, replacing, selecting text. Check out the example or the screenshot to see what all is available.

• March 13th 08 - I updated the VisualBasic.NET version of the Scrolling Textbox to Top/Bottom example. There is now another way to scroll the textbox editbox to the top and bottom my using the Windows API. It uses the SendMEssage API to be precise. I plan on doing the update to the regular visual basic version later on sometime.

• March 10th 08 - Added two new examples to the site. One is for VB.NET and the other is for Visual Basic 5.0/6.0. They are both on how to scroll/move to the top/beginning of a textbox controls text contents and likewise scroll or move to the bottom/end of the textbox controls contents.

• March 8th 08 - If the .info download server is down, you can replace .info with .org to try and get the download. Example: http://www.vbcodesource.info/myDownload.zip can be changed to: http://www.vbcodesource.org/myDownload.zip. I will try to eventually add a secondary/backup link on all of the website pages like I did on the VB Classic - Examples page.

• March 8th 08 - A new example for VB.NET has been added that will check a IP, URL, or UNC (Universal Naming Convention) name using the "IsDestinationReachable" Windows API call to see if it is reachable or not. It can return the to and from speed of the network used to try and reach the destination along with the type of network available. This can somewhat be considered a pinging example in a sense but you wouldn't get accurate reply times since the API will also get the Network type and the To/From speed before returning control to your application. But it would be good to see if a specified destination is available or not. VB 05/2008 already has a full Ping class for checking a destination. I would recommend you use that class if using those versions unless you want the network to/from speed or whatnot.

• March 5th 08 - An example for Visual Basic .NET has been added that shows how to convert Unix Time to a Structured Windows based time. It converts and displays the Unix time based on UTC Time and the Computers Local Timezone. The example displays the current Timezone and the Timezone offset compared to UTC (Coordinated Universal Time or Universal Time Coordinate) as well. This example is compatible with all versions of .NET including VB 2005 and VB 2008. A simple upgrade process is all thats needed for 05/08.

• March 4th 08 - A new example for VB.NET has been addded. Its basically a near clone of the VB 6.0 version that uses the GetPerformanceInfo() API Function to get various low level computer information. It mainly returns various memory info along with some thread and paging data. I am pretty much Computer Info'ed out so I may not be making anymore computer performance info data examples.

• March 3rd 08 - I went ahead and changed the download links to point to my www.vbcodesource.info web server. The original .org server is down and I don't have any idea when it will be running again. But anyways, all of the downloads and screenshots SHOULD be working. Please send me a feedback message if there is a download not working.

• March 2nd 08 - As you may already know is that the downloads are currently not working. Unfortunately the server that all of the downloads and screenshots are on is down at this time. All I can tell you right now is to try again later. Sorry :(

• February 19th 08 - A new example for Visual Basic 6.0 and 5.0 has been added on how to get high resolution timing using the QueryPerformanceCounter and QueryPerformanceFrequency API counters. This timer supports sub-millisecond resolutions which is better than timeGetTime and far better than the getTickCount timer. This timer will usually use a 3.6 Mhz clock on the motherboard for timing but sometimes it could use your processors rdtsc counter. Examine the QueryPerformanceFrequency returned data from its ByRef parameter to see what the ticks per second of the timer is. If the function returns a 0 then the computer does Not support the timer or you did NOT pass the APIs parameter ByRef(By Reference) which is Required. Do Not pass the parameters for these two (2) QueryPerformance APIs ByVal(By Value) because they WILL fail. You Must pass them ByRef. IF you need very precise timing, then this counter should be the way to go.

• February 18th 08 - Another example for Visual Basic.NET 2002/2003 and compatible with VB 2005/2008 has been added. This example shows how to perform basic Math calculations using string variables/objects. It shows the Addition, Subtraction, Multiplication, and Division based operators. The main purpose I guess is how to perform Math operations on Strings in a somewhat safer way. It basically uses the Val() Function which will examine a string and if the string is a number or if the string starts with a number then it will convert a object/string to a double or a Char to a integer type. IF the string contains no number or doesn't begin with a number then it will simply return a 0 which will keep your application from throwing a improper casting error message and/or crashing. A VB 6.0 version may be put up soon.

• February 17th 08 - A small example made with Visual Basic.NET has been added that shows how to use delegates and callbacks to create and use a higher resolution windows based API Event Timer. This example uses the timeSetEvent/timeKillEvent APIs which supports much higher resolutions than the original SetTimer/KillTimer APIs at about 1 milli seconds compared to 15-16ms. This timer is actually a part of the winmm.dll multi-media library that has most of the multi-media based apis like the Playsound and mciSendString apis. Anyways, its located in the .NET - Examples page.

• February 8th 08 - A new example made with Visual Basic.NET 2008 on using the Managed Windows API Timer from the DotNET Framework was added. The codes in this example is compatible with VB.NET 2005 but the project will Not load in 2005. The managed timer was added in version 2.0 of the framework which VB 2005 is based on. This example shows how to create a timer and have it call a function of your choice each time the specified interval has elapsed. This timer appears to be a managed wrapper around the SetTimer/KillTimer APIs from the User32.dll library that I made a example for VB.NET a few weeks ago. The resolution is only about 15/16ms. You can try using the Un-Managed multi-media timeSetEvent/timeKillEvent APIs which supports resolutions up to 1ms and is based on the winmm.dll library. I do have a example on these multi-media apis but never released it. I may do that later on though.

• February 8th 08 - The example on how to Clear All Textboxes, Manipulate or Set properties for all conrols on a form has been updated. The update has new codes that shows how to skip over or bypass controls specified in the code and clear or set the rest of the controls that are Not specified to skip.

• January 29th 08 - I added a new Control I made with C++ with _stdcall exports so it can be used by Visual Basic under the .NET - Controls page. The control will return some various basic cpu info like the model, vendor, stepping, clockspeed, ect... A example on how to use the library made with VB.NET 2002/2003 and compatible with Visual Basic 2005/2008 has been added to the .NET - Examples page.

• January 28th 08 - I meant to post this along time ago but forgot too. Microsoft now has available all of the Visual Studio.NET 2008 Examples that were included with the RTM (Released To Manufacture) versions as a seperate download. There are actually very MANY examples available for Visual Basic 2008 that covers everything from Excel, Powerpoint to LINQ, Tablet Based Programming, Server based, and Database programming. While the examples may NOT open with VB 2005, the codes in many of the examples should work with Visual Basic 2005 as well. Obviously examples like LINQ based source code won't work with .NET 2005 since LINQ was not supported until VS 2008. Anyways, Click this Link if your interested. The download is alittle more than 9 MB, so if you have Dial-Up it may take awhile. :)

• January 24th 08 - An example for Visual Basic.NET has been added that shows how to get the Textbox Controls - current line number (#) in VB.NET 2002/2003 (The VB 2005 and VB 2008 Textbox has a feature for this, but is Not in this example. Might add later), getting the total numbers of lines in the textbox, and getting the text/characters at the current line position.

• January 17th 08 - A new example for Visual Basic 6.0 (the code in the example is VB 5.0 compatible) has been added that shows how to use the GetEnvironmentVariable API call function to access some pre-defined variables and get/retrieve their values. You can see some Environment Variables if you go to the 'Start' then 'Settings' menu and click on 'Control Panel'. Click on the 'System' icon and then the 'Advanced' tab. Click on the button that says 'Environment Variables' which should display a window with pre defined variables and their values.

• January 16th 08 - I added Two (2x) new Examples for Visual Basic 6.0 (Codes should be usable in 5.0). Both examples are related to using two of the available system timers/counters. Since I have a few timer related examples for vb.net, I figured I would do the same for VB Classic. So one of these examples uses the GetTickCount API Function and the other example uses the timeGetTime API Function along with the timeBeginPeriod and timeEndPeriod API calls. The GetTickCount timer/counter supports about 15 ms resolutions, while the timeGetTime counter/timer supports up to 1 millisecond resolutions. Go to the VB - Examples page under Timing to check out the examples. I might make 1 or 2 more Timing related examples for the VB.COM (5.0/6.0) versions using a Very High sub-millisecond Resolution performance counter-timer(QueryPerformanceCounter) and possibly another on a super high resolution timer(RDSC).
