This means that the machine needs MDAC 2.6 or better installed and it doesn't currently have that. It's a requirement of the .NET Framework so you have no choice but to upgrade it. You can get the latest versions here[^].

Then look into an obfuscation utility to make it harder to read. You can't encrypt it or make it the code can't be seen, but you can make it harder to read. The Professional version of Visual Studio .NET (and higher) comes with Dotfuscator, Community Edition. You can buy the Professional Edition, but I don't remember what it costs.

You can add a Merge Module to the project to get rid of the warning. Right-Click your installer project name, click Add..., then Merge Module... In the list that comes up, find dotNETFXRedist_x86_enu.msm and click on it, then OK.

The same way we any of the .NET Framework classes. Your .DLL (assembly) is just another set of classes. The developer adds a reference to your .DLL, then either imports its namespace or adds your control(s) to the toolbox.

Hi all,
I'am thinking if there's someway i can call an vb exe file when i try to access a certain folder, like at first your gonna select a folder where you're goin to bind your exe, then when u try to access that folder your exe will be launched instead of windows showing the content of that folder...

I doubt that is possible, if it is, it would involve a system wide hook. Not sure you can hook on the opening of a folder.

I don't know of any way to do this. It MAY be possible by writing a Shell Extension (warning! This involves LOTS of COM interop), but I don't know of any examples that are triggered by the selection of a folder, or anything else for that matter.

I don't know if this would work, but if you were to hide the folder and create a shortcuct to your program with the shortcut named the folder name and the folder icon. So when the user clicks on the what they think is the folder, it opens your program, and say, if your program is already open, it just redirects to the folder or something.

This is information that should be passed into the method by the caller. Since your .DLL can't determine what type of application is calling it, Application.StartupPath might not have any meaning.
But, if you're absolutely sure that the only thing that will call your method is a Windows Forms app, you can add a reference to the System.Windows.Forms.DLL, then do something like this in your DLL code:
Imports System.Windows.Forms
.
.
.
Dim path As String = Application.StartupPath

I don't see any error in this statement. What makes you think otherwise ? What error are you seeing ?
wait - operator is probably a keyword in VS2005, which means it's a word ( like string or dim ) which has special meaning in VB and so you can't use it for a variable name. Try calling it op instead or something.

Christian is right. "operator" is a keyword and can't be used as a variable name.
It CAN be done though. Although, I don't recommend doing this because it makes your code harder to read. To use a keyword as a variable name, you have to enclose the name in square brackets:
Dim [operator] As String
[operator] = "+"
It's best to just rename the variable to something else:
Dim op As String
op = "+"

im doing project on image processing that include inverse,threshold,smoothing filter,convolution and edge detection function. im using VB 6.0 and currently i only able to load the image. the image im using is bitmap type format. but im stuck at reading the pixel one by one. how am i going to do that? can you give me an example..

VB6 is pretty close to useless. Can you move to VB.NET ? Apart from being closer to a programming language (:P), you can actually get ALL those filters in C# from my image processing articles on this here site, which will convert easily to VB.NET.
They won't convert to VB6, nor do I think you have any real VB6 options to speak of.

Hi,
I want to populate my list box with data from a column in my table in an SQL Database.
Table name is tbltest, listbox is lstnames and column name is names.
I want to add names from tbltest to lstnames.
Please help.

Which part are you stuck on ? Do you know SQL ( tragically, lots of people fancy they are writing database apps but don't know SQL nowadays ) ? Do you know how to interact with your database in code ? I assume you know how to set the datasource of a listbox ?
