You might get an answer if you ask this in the ASP.NET Forum. Your question has nothing to do with VB/VB.NET.

Problem:On Adding a control to designer at a specified Mouse Position
Effect: Control moves to some Default Position
Expected Result:Control should be placed on those specified co-ordinates where mouse pointer is pointing

Drop all the "Problem, Effect, Expected..." garbage and just ask the question.
Are you seeing this with all the controls or just certain ones, which ones? Which version of VB.NET are you using? Are the controls snapping to a grid if you move them around with the mouse?

I am working on a complex project. To make it easier I decided to produce some components in 4 different namespaces. These components were later imported in to the main project with an import statement at the top of the main project.
The program works well and i was considering writing all my projects as classes and components until this afternoon when i decided to deploy.
I produced the installer without error. I was able to install in another computer but the program just would not run in this second computer. The error message was
Processid=0x5e8(1512), thrad id = 0x2dc(732)
what does this mean and what did i fail to do.?

It sounds like your .DLL's for your components didn't get added to the installation, or are not installed where the Loader can find them.

Why are there two .DLL's with the same name in your Setup Project?? Where did both of them come from and where are they being installed??
If you're app is using 4 different library .DLL's, I only see one in this project. You're missing 3 of them. You'll have to straighten out your duplicate .DLL problem and add the other three missing assemblies to your Setup Project, at least.

Because of the difficulty I experienced I decided to rewire the program a little
The original Windows Application had 4 Windows Control Library it needed to function properly.
I decided to lump all the user control inside a single WindowControlLibrary.
This is what I did:
I created a project in vb.net using a WindowsControlLibrary I called it NAWADriLCiLibrary.
It houses several user controls that are all used in a WindowsApplication1 I call DriLCalLc.
The database is in MS Access and is called Hydraulic.mdb
The database is in the window application.
The command buttons to save, edit, delete into the records of this hydraulic database are in the window application. These buttons are linked to methods and property of the user controls in the windowControlLibrary.
In my developer PC after I have produced the NAWADriLCiLibrary I build it, using the build menu – build solution on top.
Then I copied the NAWADriLCiLibrary.dll generated from the NAWADriLCiLibrary/bin/ NAWADriLCiLibrary.dll into the DriLCalLc folder. After this I set a reference in the code of DriLCalLc pointing to this. I did this by right clicking the add reference and selecting this .dll when the “add reference “box came up. To enable me use it in my code I then at the top of the code add an import statement
Imports System.Drawing
Imports System.Windows.Forms
Imports NAWADrilcALclLibrary
Public Class Form1
End Class
What am I required to do? How should I produce my Installer?
Also thank you for your guide I will read the text at the hyperlink now.

Do not set a reference to the .DLL file itself. Make your control library project part of the same solution as your application. In your application project, set the reference to the control library project. Do NOT copy .DLL's into the bin folders of your windows app project. This will lead to "unable to find version errors", or problems where you make a change to the library code and can't figure out why the changes don't show up in your windows app.
To this solution, add your installer project. Pick the Setup Wizard to make this a little easier and make sure you add the Primary Output from both the Windows application and Control Library projects.
That should about do it...

Also I have some questions to ask
1: What if I am developing the User control for third party use and do not want to share my source code.
2: How can I install the dotnetframework at the same time to avoid the message that always appears in my deployment build history?
Message:
WARNING: This setup does not contain the .NET Framework which must be installed
3: If the developer of the window application is not privy to the source code of the WindowControlLibrary How would the developer of the window application use this .dll
Thank you for your patience.

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[^].
ihe wrote: 1: What if I am developing the User control for third party use and do not want to share my source code.
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.
ihe wrote: 2: How can I install the dotnetframework at the same time to avoid the message that always appears in my deployment build history?
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.
ihe wrote: 3: If the developer of the window application is not privy to the source code of the WindowControlLibrary How would the developer of the window application use this .dll
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

pl anyone can suggest me where to declare the var operator iam jus beggner and this is my first ques.
pl solve

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.
