Which vb.net object is the best match for the vb6 collection class? Specifically, I would like to be able to access the Item property with an index or a key string. I wrote my own class that inherits from the collectionbase and uses an arraylist to hold values, but i'm missing the Item(string) property. I suppose I could iterate thru the...

When I'm changing a forms name in the project and this form is a startup form (set in the project properties), I get an error that the function "sub main" is not found. The visual basic should automaticly change it's name in the project properties as it changes it automaticly in the code window. Is there any fixes for it? (I'm using Visual...

Is there a way to overpass the impossibility of VN.NET to accept the multi heritage, that is to allow a class to inherit from TWO mother classes ? -- Bernard Bourée bernard@bouree.net

I have a program written in Visual Studio 2003 Visual Basic. I would like to move it to Visual C++. Is there an automated or relatively automated way of doing that, or do I need to recreate all the windows by hand?

I have come to greatly respect both Herfried & Cor's reponses and since the two conflicted, I wanted to get some clarification. My orginal post: Herfried, maybe your example here can get you to answer a question I've wondered about for a while. With Me.Label1 .Text = ... .Refresh()

I made a Usercontrol that must have AutoScroll set to true when it is used. So I set it to True in the Load event. However the property still shows in the properties window when the control is placed on a form. That's confusing. How can I make that property not show in the properties window?

Hi, The Multi column comboBox is a well spoken control, that a lot of people desire, and a lot of people buildtheir own. I tested a lot of them, but none really was what i wanted to have. But does anybody knows where I can find the best Multi column combobox? One that supports a lot of columns, possiblities to get the values in each column...

Variables that I would like to make available to all forms and modules in my program, where should I declare them? At the momment I just created a module and have them all declared public there. What is the normal way to do this? Thanks, Thomas --

I run this program and to exit click the X in the upper right corner. But apparently it isn't really ending the program. If I return to VB and make changes then try to rebuild the app it says the exe is still in use--I find it is still a process in Task Manager. What do I need to do to make clicking that X actually end the program? ...

Hello, I have this problem: I wrote some DLLs with VB.Net 2003 which I use with my programs. But I want to avoid that I have to go down to "DLL hell" and to copy all used dlls into each program directory. Does anyone have an idea how I can avoid that? Thanks in advance!

Hello, I am a newbye, and I'm trying to write a simple application. I have five tables with three columns; all tables are identical; I need to change some data in the first table and let VB updates the same data in all other four tables in the right places. I know it would be possible by using the ForeignKeyConstraint object. I have created...

I'm new to VB.net and I want to upgrade an application from VB6 to VB2005. The VB6 application uses an invisible WebBrowser control to access some pages and parse the content. Is there a better way with VB2005? Nothing wrong with the WebBrowser (besides the memory leaks), but since I don't need to show any web page content I was wondering if...

I am getting the following warning for the below function. I understand what it means but how do I handle a null reference? Then how do I pass the resulting value? Regards Warning 1 Function 'Dec2hms' doesn't return a value on all code paths. A null reference exception could occur at run time when the result is used.

when you guys have a solution for _ALL_ of those scenarios is when I stop VB 2005 doesn't support code reuse or portability I want to know what I am supposed to do.. am I really still supposed to cart around _TWO_ ide so that I can write VB6 scripts and test them; and then rewrite them into VbScript? and then I can take my VbScript...

I thought it would be nice to display some animated GIFs on some of my forms. I put a PictureBox control on a form, and loaded my GIF file in. It animates, but not properly. It seems very jerky and dwells on some frames longer than it should. Searching for this problem, I have found several people who have stated that animated GIFs don't work...

Can anyone tell me if its possible to do multiple event args in vb.net?

VS 2003, vb.net, sql native (MSDE)... I have railed against the inconsistency of the Nothing key word. The documentation says is will assign a default value for any datatype...well, not exactly. Here are 2 more examples: Example 1) dim x as string = nothing, the value of x is nothing (instead of string.empty). When you add a row to...

This is the scenario: I have a VB.Net project comprising of a few Forms. On Form1 I have more than 20 buttons. There is a very lenghty code written in click event of each and every button. Right now I haven't used any sub procedure. I mean to say I am writing the code directly in the click event. So it's become very lengthy and therefore to...

I'd like to develop scrolling text in an 'about' box, similar to the kind of thing you see in lots of apps (eg photoshop). I could use flash to do this, and I know how to, but I would like to know if I can do this in vb .net only. Thanks for any help. Bernie Yaeger

Hi Am having a problem with an app I wrote to test patch delivery. I contact a remote PC, and get it to run a patch which is installed on a server. It works fine if I use psexec for example and I know it's not NTFS/share-level security at fault - it's readable to everyone which is usually enough for scheduler or any other...
