Create An Interfacing Software For The Micromouse
Oct 17, 2011
im doing a school project, which is to create an interfacing software for the micromouse. one of the task is to list all the calibrated values in the mouse from hyperterminal to the "textbox"s in my vb program. In the hyperterminal, normally when i pressed "3" and "enter", it will wonderfully display all the values that are calibrated in the mouse. But when i try to list values from a button i programmed in VB, only 1 or 2 values are shown.... why? this are the codes for the button to list value

I'm trying to interface .NET (C# or VB doesn't matter) with a Siemens PLC S7 200. I can't however get a connection set up. I'm working on a Win7 64bit machine but can't seem to get it working on 32bit either. I got two files:
Interop.OPCSiemensDAAutomation.dll
Siemens_s7-200.dll
From another project which I'm trying to migrate to a newer system. However I get a com exception all the time.
Retrieving the COM class factory for component with CLSID {01704EBD- 4B5-11D3-9C09-00105A3DD3AC} failed due to the following error: 80040154.
I've already tried libnodave and can't seem to get that working either.
I couldn't get Siemens PC-Access to install on this machine, will try on a WinXP 32bit later. I read something about I need an OPC server or something on the machine?

I have a 64-bit project(which has to be 64-bit as it is an Outlook 2010/64 bit addin) that needs to interface with another Dll of mine, whose job it is to scrape file metadata out of files using the windows Shell32 dll. Now, as you may of guessed, this is posing compatibility problems as I am crossing that 64/32 bit boundary.
I read an article (ok skimmed it, whatever) and from what I understand, it suggested that I use COM as an intermediary and to bridge this gap. So, My question is, can I build a shim DLL in say VB6 (i know, i know) that would act as my com reference and pass the calls on to my 32-bit dll from my 64-bit addin?
Do I create a VB6 COM Dll, reference my .NET assembly and pass all Public functions out via a similar interface, then reference the VB6 dll in my 64-bit addin? is it just that easy?

I am trying to interface with a Sylvac Gage over the Serial Port, but I can not get read any information sent by the gage.I am using the IO.Ports.SerialPort Object (called serialPort), and I can successfully write to the device. I can tell it to turn off by: serialPort.Write("off" & vbCrLf)But I can't seem to get any information back from the Gauge when I ask it to send information serialPort.Write("?" & vbCrLf)

Is it possible to make a virtual interface represents the value of an input? For example, if we have a program shows the level of a liquid in a tank and we want to represent the level virtually: as the calculated value of the level increases, the level (and color) filled in the tank shown, increases as well. Example: If the value is 100, the tank ( a rectangular ) will be shown full and green. If it is 0, will be shown empty and red.

Introduction: Probably a year or more ago I asked if was possible to use the Mathematical functions in Windows Calculator or use any DLL file it may use without a satisfactory answer. As I require the greater accuracy of Windows Calculator in String format. Would it be easy to keep switching between a Vb.Net Form windows based application and Windows Calculator and, using SendKeys, get results back to a Vb.Net application using Copy & Paste via the clipboard but to do this in an automatic fashion at all please?
What I am particularly interested in is getting Log10 or LogN results and also doing ARC or INVerse LOG10 or INVerse LogN calculations. But I require the greater accuracy of windows Calculator. Additionally, would it be possible to assign a keyboard keymap to each key in Windows Calculator so that, for example, the L key would be assigned to clicking the LOG10 button, ALT for the Hyp checkbox, SHIFT for the INV checkbox and so on?So imagine sending key sequences to Windows Calculator to completely automate it. And Windows Calculator has been updated too in WINDOWS 7, would that make it any easier to work with?

I've designed my own encryption application in VB 2008 that has a free tools section where users can choose a particular wizard to use from the drop down. The javascript wizards display the code required to put in their own sites. I already created wizards that users can well, use.I see people have their own "contact form wizards" on their websites all the time. Where users can use the wizard and get the displayed code to copy and paste on their sites. But trying to locate source codes to these things is very aggravating on the web.So what I want to do is create my own "form wizard" like out of javascript, that allows the user to put in some information then get the displayed code to put in their own websites. I'm not looking for the generator such as the online form generators.But the javascript source code(s) for the generator itself.Then I could simply put a form generator inside of my VB-app, that will allow the user to use the wizard, then get the html code to paste in their own sites. Preferably not the PHP one because the php backend is very difficult to put in a VB app.I know that it can be done. For example copying a web pages source code then putting it inside a string, then calling that string from a button click that will open the javascript page in the webbrowser inside the VB app.

I have used VB (versions 2 - 6) through many years; however, I am crash-course training myself into the VB2008 / VB2010 world kicking a screaming. I would like suggestions as to what SQL database access method should I focus more on in my learning process without making me feel that I'm a million years behind. I know I have WinForms where I can create a datasourse and drag / drop fields or tables on a form to create a grid (not really what I'm looking for).
My trouble isn't so much designing the form but in how I access the database. Theres XML, LINQ to SQL, ADO.NET, and many other methods. Not only do I need to grasp these methods quickly but I also need to know what type of projects I should create. What I mean is...I was thinking that I would design a WinForm app; however, I see that there are WPF apps and others to chose from. This is getting deep. I know it depends on the project that I'm working on. My plans are to write an app based off of either an SQL Express 2008 or SQL Server 2008 database. This first app will be standalone for now but may later become multi-user. I know I'm far behind on my learning curve coming from VB6. I have read a bit on VB2005 / 2008 / 2010. I own
both VB2008 and VB2010. I use VB2008 at work. I know ADO.NET is still alive but by what I read online, it's a dying method and is only kept for backward compatibility. XML and LINQ to SQL and other methods are all pretty new to me.

I'm in the process of trying to create a class that will allow me to create windows shortcut; Im using the following PDF file that gives me the shortcut file structure.
Ive been able to successfully load a shortcut file and parse its Lnk File Structure but now Im on the Shell Item ID List structure but I cannot find the Structure of the ITEMIDLIST anywhere
Furthermore I know I could use the Windows script object, but this is a dependency Im trying to avoid if I can, hence writing my own Shortcut class.

If I have a large number of classes, each similar to the other in certain aspects (they all share a common base class, but each does things differently), and I need to create Windows forms for each to allow easy changing of their values through a GUI? Create one matching form for each object in VS' forms designer, Or Use code to create the forms dynamically at runtime.
#2 makes the most sense to me, because a lot of these objects will share very common features of the form, notably "Ok" and "Cancel" buttons. But one object might need to draw a textbox on the form while another might need to draw a combobox. Not to mention, if I want to put icons on the "Ok" and "Cancel" buttons, I'd have to do this for each copy of the form in designer, and that sounds like it could get out of hand quickly.But is drawing forms through code sane? VS' forms designer is pretty sophisticated and designed to make life easier. Am I wise to consider ignoring its functionality and diving into the trench warfare of forms design through code? Or are there examples of automating form creation based on an existing object's properties?
