I've created a simple tool using a datagrid and adding functionality for cutting, pasting, deleting, adding rows, etc. The select users can create new, save, edit, delete from the database. Is there a better way to do this with some of the new technology from visual studio?
View 1 RepliesThis program is very difficult for me, but I must get threw it or I cannot finish... What I am doing is making a Database of foreign Languages with the spelling of the words and the pronounciation inside the database... The USER enters a paragraph of words into the translator textbox and pushed translate. The program has a DATABANK of words with the phonetic spellings and matches the word, then translates to phonetics. The problem is that new words keep appearing inside the language. So I incorporated a Database of 2 fields

Lately I've had to do a bit of programming in VB .NET. It hasn't been too difficult, but the lack of proper documentation or good tutorials has been annoying me. I'm used to finding a lot of relevant info when I google a programming question, or term, or method name - but it's been more difficult with VB .NET. Anyone know of any good tutorial/documentation sites for VB .NET?
View 3 RepliesI noticed how many of Visual Basic programmers want to develop a webbrowser. So now I had the thought: why not put our knowledge together and make a webbrowser that every other webbrowser developer gets a headache from trying to understand how we pulled it? I have the base function like opening a new tab, browsing, implementing favicon and changing from tab functions working.Accept browsing with it there will also be brought out a webdeveloper version of it.If possible i would like to us a other browser control then the webbrowser control standart in VB2008/2010.If you would like tovolunteer and develop a webbrowser with an entire team contact me via mail!

View 4 RepliesWe develop small applications for various customers. I now got a task to set up some coding guidelines for in-house and external programmers. (Management know nothing about development and only see the problem in transferring projects from one developer to another. Customers pay by the hour and development is a small part of total project so code quality is a non-issue)My first step is to set up guidelines for C# and VB.Net (SQL will probably come later).(Most code here is created with CTRL-CCTRL-V and testing is done with F5.I have tried to introduce unit testing / code review but that is not going to happen. Static analysis is the only way forward at the moment)I am most comfortable in C#/C++ (but sometimes work with existing VB6/VBA/VB.Net code) so setting up C# guidelines is pretty easy: [code] For VB.Net I need to replace StyleCop with some written guidelines but how do I set up the VB.Net compiler.Personally I never code without Option Explicit / Option Strict etc but if I do that on our VB.Net projects I get hundreds of warnings/errors (implicit conversions, default return type/value etc).The VB developers does not seem to have a problem working without help from compiler warnings. I do not think their productivity generally differs from C# developers (it is more a personal thing).I do not want to enforce my own preference for static checking so my questions is: What warning levels are reasonable/best practice for VB.Net development?

I am sure the screensaver wasn't meant to be used in this manner, but I have created an interactive screensaver for the company I work for which acts as a checkout station for calibrated measurement equipment.Part of this process is printing out a sticker using an SII SLP Label printer which is attached to the computer with the checkout station. Printing with the printer works just fine over the network from another computer (not running the program as a screensaver), but for some reason I am getting a -16 error (I believe that is "Unknown Error") when the program as a screensaver uses the local SLP printer. The only possible reason I can think for this happening is that screensavers aren't allowed to access printers. Is there some way to give the screensaver permission to use the printer? Currently the screensaver is able to access files on the network file share (such as the equipment database) just fine. If I were to create a TCP/IP server that acts as a proxy or go-between for the printer so that all the screensaver does is connect to localhost and tells the server to print would that work?

View 3 RepliesI am trying to sort my report on the values in a column. The underlying query consists of a director colum a movietitle column and a rating column, for every movie a director has directed there is a record which off course shows the rating in the ratingcolumn In my report I have grouped by Director and created two other columns which are called: Nr of Films and averageRating. in the design view i used two functions to accomplish this. the first is: count('the field of the rating') and sum('the field of the rating')/count('the field of the rating'). This is working... but now I would like to sort the column, Nr of Films. I think I have to do this with interactive sort of the textbox which holds the column name(i.e. Nr of Films)

I am wiring a startup script JavaScript function on Page_Load to fire like so:
ScriptManager.RegisterStartupScript(Me, GetType(Page), "page_init", "page_init();", True)
This function calls a couple of different functions to setup the page. One of those functions checks the document.readyState and makes sure it's "complete". This deals with images and I want to make sure everything has been fully rendered.
if (document.readyState == "complete") {
Everything works fine, until I need to write a byte array to the outputstream (using either Response.BinaryWrite or Response.OutputStream.Write() to give a file to a user. After that, the document.readyState is always "interactive", until I navigate off of the page and back. I have even used a setTimeout(myFunction, 1000); call if document.readyState isn't complete to recursively call the function until it is complete. It never reaches "complete".
I have researched this myself for quite sometime, and cannot figure out this behavior.
I have a problem reading data from an RFID-reader. I connect to the reader by tcp and wait for DataAvailable to be true, then reading the data until I got a end of data character. Then I just go back and waiting for a new DataAvailable. This is done in a own thread for the function.
There seems to be some kind of timeout, If I don't got any data in a couple of minutes, then it just sits there in the do/loop waiting for DataAvailable. I hold the card to the RFID reader, it beeps, but there is no data available. I don't get any exeptions, and the information says that the clientsocket is still connected. Are there anything more I can check?
If I put the card to the reader in a minute-interval it seems as this will never occur. So 2-3 minutes idle:ing seems to do this.
Here are my code to read data from the socket, I have taken away some irrelevant code:
Sub test(ByVal ip As String, ByVal port As Integer)

Im working on a HSD 32 bit data bus to serial converter via a microcontroller. Now first I want to make a sort of data sniffer to read the data bus (32Bit) .All on the controller side is working and the stream of bytes are coming in via RS232 as 4 bytes in HEX like FD,A5,45,8B . I already converted the bytes in Dec and ASCII to determine what is passed true the bus and how fast and stuff.. Now that is all correct and working very well if the LSB (least significant bit) of the 32 data bus is Data line 0 and the MSB (most significant bit) is Data line 31 but if that is not the case I need to invert the 32Bits (like as I would invert the connector on the bus) . How do I best do this using the 4 bytes I send from the micro controller.
Example:
(MSB) 01001000 01100101 01101100 01110000 (LSB)
HEX= 48 65 6C 70
DEC= 72,101,108,112
ASCII= H E L P
I need to invert it with a button to:
(MSB) 00001110 00110110 10100110 00010010 (LSB)
HEX= 0E 36 A6 12
DEC= 14,54,166,18
ASCII= (SO) 6 : (DC2)

My problem is when the new data comes out from the API, if it is equal to the previous data and it will appear 0. But what i want is the new data comes out is 0 and it will equal to previous data. e.g: first data comes out is 12.00, in above case, if the second data comes out is 12.00 but it will shows 0 which means unchanged. But in my case now, i want if the first data come out is 12.00, then if the next data is unchanged (0) and it will appear 12.00 and so on.
