View 9 RepliesI have been making a order processing system for a friends company and have 99% completed it. i was going through everything double checking all the components and i put a "DotNetBar" component on the form but then deleted it as i didnt need it. i only have a trial version of the dotnetbar and do not plan on publishing the software with the component on.
so after i deleted the component from the form i built a test version of the system and installed it on a different computer but when installing an error appeared saying something along the lines of dotnetbar component cannot be found. i couldn't find any trace of the component in the page.designer.vb file.
im by far no expert in vb (this is the first real program i have developed for actual use), i cannot find any way of getting all traces of the component of the project.
I am creating an interface with several textboxes and HTML component and several buttons.But when I drag any textbox onto the existing form they line up vertically one under the another or they attach directly together on the same row.

Can someone tell me what I need to do gain this simple freedom in vb.net
View 3 RepliesI retired recently from a job where we had VS2010 Professional for doing ourdevelopment. Now that I'm retired I can't afford "Pro" and cannot find the component than looks like this (see above). Is/was that component left out of the "Express" version? Do I have to "load" it (and, if so, what name should I look for)? I vaguely remember it being some kind of container for other components.As a follow-up question - can anyone provide a (readable) example of creating a two dimension array of this item I could study?

View 3 RepliesI have an error that keeps regenerating when the form is closed and open back up.
1) Windows Form Application (Project: TestProject)
2) Add class in same project:
Public Class Test : Inherits System.Windows.Forms.TextBox
3) Drag and drop into the form within the project (works fine)
4) Close form
5) Re-open form... then error about the class Test in the project not defined
Actual Error: Type 'TestProject.Test' is not defined.
Is there a best way around this besides creating a separate project and putting the 'Test' class in that separate project and referring that separate project in the 'TestProject'?
Modified Added: By the way... i've used Global.TestProject.Test... but then again another error generate with the custom property within the 'Test' class.
I have a simple Win App VB project with a single form in it. I also have an Active X component which I am adding onto this form. This component is made in C++. On building the VB project i get the message "COM Reference 'CPPLib' is the interop assembly for ActiveX control 'AxCPPLib' but was marked to be linked by the compiler with the /link flag. This COM reference will be treated as a reference and will not be linked." but it compiles successfully. When i try rebuilding it or opening the view designer of the form VS2010 crashes. The project is locally creating two dlls namely "Interop.CPPLib.dll" & "AxInterop.CPPLib.dll". I have made the Embed interop types False for both these references.

View 13 RepliesI have a pretty large project built in vb.net under VS 2008. This project is heavy using SQL.
There is one part of the project, that I need to make a smaller project. So I am taking 6 forms out of 23 and adding them into this new project. Instead of adding the data set, I built a new one. With a different name. But it's connect to the same database.
First of all, is this a good way to make a sub-project, or is there a better way.
Secondly, I am running into a problem where my table adapters are not members of dataset. I get this error in the design code. I know it's not a good idea to manually change this code.

I've been assigned to start a new Logging Project from zero in VB.NET.The final exit of the main project is information organized in paragraphs like this:
[code]...
Every paragraph correspond to a database connection. Every connection is made with an entire diferent database.i need my logging project to save everything the user does, so the logging exit would be like the system exit but with exceptions and other important information like this: Paragraph's title 1 Paragraph's content 1.Paragraph's title 2 User wasn't able to see this information because an exception ocurred: System.WhateverException:couldn't connect to WCF.as you can see the exit is the same but i need to create a detail log because the information is delicate and the DBA needs to now wich user did what and what was the response of the system. Also i need it to be and independant project so i can re-use it in another projects. Seeing the final exit of both the main project and the logging project, what would you recommend me to use for logging in .NET?
i'm currently working on building a program that will take a MS Access database system produced by my company and create a VB.Net project with all the forms in it (obviously the code should be manually done, but to save time the forms and controls can be produced automatically).I have tried Googling and seem not to be able to find anything about this (which probably means I wasn't searching with the right keywords), I was wondering whether anyone knows any good resources on how to create the VB.Net project programmatically as I already know how to do all the access stuff.
