Usercontrols have nothing to do with it. You've obviously copy and pasted this code, do you have any idea what it does ? Resources are stored in your file and retrieved using a fully qualified name. You're building the name by asking what the name of the application that is running is, but that's not the name being used in your dll, which has a different name. Have a look at the string that's being generated, and then replace the application name with the dll name, that should work. I've never pulled resources from a dll before, but I'd imagine that would be the way forward.

Yes that is what i did, i couldnt find the rigght info just code. So let me ask the question the right way i would like to make a usercontrol that hosts a few bitmap images. what is the best way to do this or can you point me in the right direction. I am doing what i can to learn on limited resources and no real experience.

Easiest approach - why not just load the files from disc ?

i'm not looking for the easy way out. i want the images to load when i use the control on any app.

I think this will help. I understand what you were talking about. Thank you for your patience and help. I need all that I can get.
By the way any tips to gaining knowledge and experience would be very appreciated.
Thanks again.

To be honest, I was just thinking that I've been neither patient, nor helpful  Normally, I'd whip up a project to work out the definitive answer, but I'm under a little schedule pressure today, and still trying to keep my batting average up.

What's worked for me is to always learn why things do what they do, find a code sample and then use MSDN to nut it out, ask lots of questions in places like this one, and invest in good books, which I read at least twice. I nearly fell over today, I was away sick and some orders come in, I got two books, both over 800 pages, and one > 1000. I had no idea they were so big ( they are both ASP.NET, one on security and one on improving performance ). I've got a lot of reading to do....

Don't know if 've understoog your application but why don't you use an Imagelist to store and load images. It's easy to access and use.

i want to make a custom checkbox that uses several predefined bitmaps. how and where do i store the images and call them. i want to be able to use in any project. i have come close but the project i want to use it in has to be add to the usercontrol solution or it will not work.

I bound some textboxes to a well-defined datatable. By well-defined I mean I created each columnn of the table manually and defined the dataTypes of each column.
If I try enter in non-Date data into one of the textBoxes bound to DateTime Column, the original date value gets reverted once I change focus. This is GRRRREEAT! but how do I alert the user on why this has happened. I need to somehow intercept this event.

someone please send me an article/link to one on validating data entry controls for vb.net forms.
I have an application with 5 different developers working on their own forms. The challenge is to create some sort of base class that will force the developers to use the same validation controls and or regular expressions on string textboxes, date textboxes, integers and so forth.

I am an experienced VB.NET programmer who has a 13 year old son who wants to learn to program during the summer. Having been homeschooled for several years he is good at independent learning. Does anyone have any good recommendations for books, web-based classes, video tutorials, etc. that do a good job of teaching beginning programming using VB.NET? He could study it during the day, and then I could tutor him after I get home from work. FYI, he is an A student and learns quickly.

Hi Mark,
I just purchased and finished reading this book Mastering Visual Basic.NET[^] from Sybex. The coding starts out very basic and moves through VS.NET and the VB.NET classes. The coding may be just barely over his head at 13, but if he's making A's in school I'm sure the reading context is right at his level.
Otherwise, I have read several of the "Dummy" series of books relating to VB.NET, ASP.NET and Database technology, all of which where great reads because the content is almost humorous but can teach even the most veteran of us a few things here and there.
Hope this helps!

I recomand you to begin learning C# because it is more strong,security and logical language then VB.NET....
I was been programmiming in vb.net but i paste in C#.
here is one link http://www.projectw.org here u have to register and search for books, applications, and much things.
I hope this helps to you.

*sigh* I was hoping to recommend you learn C#....
The best thing to give him is the URL to this site, and a decent book. If he can ask you questions, and ask them here, then he should be right. Video tutorials/web based classes are a waste of time for anyone with more than 3 brain cells IMO.
MSDN samples are another good place to start.

Thanks. As a matter of fact, I do know C# and can develop with it. Before .NET I have about 10 years experience teaching and developing in C++. However, for various reasons, I simply prefer VB.NET - just as some prefer Mac's or Windows environments.
I have never used a video tutorial, so I appreciate your warning.

A video tutorial is like a teacher you can't ask questions  And online classes aren't going to offer any more than posting questions here will, IMO.

I was wondering if there is a way in VB6 to programmatically prevent a listbox from droping down?

I own a licensed copy of Visual Basic 6.0 and recently reloaded Windows XP and Visual Basic 6.0. I cannot use F1/Help - it gives message: "The MSDN collection does not exist." But Visual Basic 6.0 did not come with a MSDN CD/CDs. I had this capability before (Press F1, Help opens).
I know that MSDN is available online, but I need it on the road, local on my machine. I have searched long and hard for answers, but can't find how to re-install MSDN with my Visual Basic 6.0 package or anything online.
I'm sure I'm not the first one to have this problem. It might be useful to provide a solution on this site.
I am running Windows XP with SP2 updates. My Visual Basic 6.0 package includes one CD, plus Visual Studio 6.0 Service Pack 4 (I downloaded Service Pack 5). No MSDN CD.
When I run the setup.exe from the Visual Basic 6.0 CD, all the options I get are:
Microsoft Visual Basic 6.0
ActiveX
Data Access
Professional Features and Tools
Graphics
Tools
When I "Change Option" Microsoft Visual Basic 6.0, I get the following "sub"-options:
Microsoft Visual Basic Core Files
Package & Deployment Wizard
Wizards and Templates
WebClass Designer
Nothing about documentation. That won't happen, I suppose, unless I had a MSDN Libary CD, which the install asks for at the end of installing Visual Basic 6.0. But I know I never had a MSDN Library CD. How, then, did I have it working before? That is the current mystery.
I'll continue to be on the hunt for a solution.

"But Visual Basic 6.0 did not come with a MSDN CD/CDs" ???
Every version I have seen, Did come with the CD's
I don't know that this is of much help to you.
sorry,

You'r going to have to find that CD. The current versions of MSDN no longer integrate with Visual Studio 6, or any sub-version thereof.

Thanks, Dave and progload - I guess from two sources, I need that CD. I think I have a copy of Visual J++ from the Visual Studio 6.0 line - it's stored away in a trailer. Perhaps that box should include the MSDN CD with Visual Basic 6.0 Documentation?
