Hello,
I downloaded following Chess program written in classical VB, however after trying to convert it to VB.Net code via the conversion wizrd I got numerous errors which I couldn't resolve. Since I'm not familiar with VB.net, I need someone instruct me on the problem or provide me the upgraded code.
Many Thanks in Advance

Which version of the converter are you using.
Although I have little to no experience with it I hear that the 2005 converter is much better than previous versions.Humble Programmer

I'm using visual studio 2008.
The problem is just about handling of arrays (as compiler listed the errors). But I think with a little work it can be surmounted.Real Eyes Realize Real Lies.

There's just WAY too much information to go over and way too many possible problems. There's no way to answer your question in the form you want.
Personally, I don't recommend the Upgrade Wizard at all. There is no coversion tool that will do a good conversion with no errors. You're just going to have to rewrite from scratch or find an example in VB.NET.

I am getting an error that I cannot reproduce in the dev environment..
Here is the information I have captured from the deployed app.
Please tell me what this means if it means anymore to you than myself. Also it would be cool if you could tell me why my stack trace does not show the line numbers like many other stack traces that I have seen.
This error is very random there does not seem to a consistent set of steps that causes it.
Error number 5
T Create__Instance__[T](T)
An error occurred creating the form. See Exception.InnerException for details. The error is: Exception has been thrown by the target of an invocation.

Hi,
in order to provide line numbers, the EXE (and the DLL files it depends on) need the presence of the PDB files next to the files they relate to.
The actual situation and problem description is too vague to work on.
|
|
|
|
|
So I would have to deploy in Debug mode this that correct?
If my understanding is correct the only problem that deploying like would cause is that somethings would not be optimized is that a correct assumption.Humble Programmer

|
|
deploy a debug build and include the PDB file(s), that is what I recommend.
|
|

| Do you know what the error could be referring to? Humble Programmer

Just on a hunch, are you using the "default form instance" facility that VB.NET provides to help with upgrading VB6 apps? My guess is that there is some problem that is occurring the first time you use frmClientCommon1.
Did you do what the error message suggested and look at the InnerException? The inner exception should provide you with more useful information about what is going wrong.
Also, as a general tip, think about what is different between the dev environment and production environment. Different connection strings needed? Missing data files? Registry settings? Basically anything that might be set up differently.

Hi,
Im looking for a good VB article that i need to use in a renewal automation for an insurance product. Found the hands on labs for windows workflow (VB.net) edition and half of its in C#, which isn't a problem but i have a tight deadline to follow.
Many thanks

You, more than liekly, won't find one for such a specific requirement. Your best bet is to learn from other examples and write your own. C# is easily convertible to VB.NET, so you've already got examples. If you were looking for copy'n'paste code, you will not find any.

I'm not entirely sure what your question is here. If you are looking for a good introduction or overview of WF, then I would recommend the Ode To Code articles[^]. I found these very useful when I was trying to get my head around .NET WF. Again, the examples are C# but as someone else pointed out, it's not hard to translate it to VB.

I am wanting to make a desktop application to go along with my website. The idea is to display all media mainly movie files in the desktop application and be able to stream them. I will be using a MYSQL database and a login system which I have already setup.
Could anyone help me on how I would go about displaying and streaming media content. For example how adobe media player does it but of course on a much smaller scale.
Snippet codes or ways of doing it would be great please. If you give me snippet codes, just display the main points, then i can build on it.
Thank you for any help received,
Robbie.

You may also want to look into Window Media Encoder[^] (free!)
The Flash Video Encoder and Flash Media Server, as far as I know, only come in Flash Professional, which can be found in Adobes CS4 products: Web Standard, Production Premium, Design Premium, Web Premium and Master Collection. None of these are free.

You can use VB6 DLL's in .Net, but you have to ensure it is public class and public methods, as it is these that VB.net will call.
Is it on the same machine or across a network?------------------------------------

It is an Extension DLL or a Regular Dll , if an extension dll then it can be used for the Same language in which it is written  Best Regards,

What exactly is a "regular" Dll? And what is a "Extension" Dll? Please explain, this wording is strange to me.
