Posting Data To A RichTextBox On A Form From External Objects
Apr 13, 2010
Background: My VB .Net application is a back-end solution that works with a proprietary Linux-based middle-ware messaging architecture developed by our company. My application references to the middle-ware DLLs, obtains connectivity, and subscribes to specific broadcasts with the middle-ware. When the broadcasts are received, it handles processes them and inserts/updates certain tables in a database. To do so, it has specific notification classes to handle each type of broadcast. These classes adhere to the inheritance model imposed by the middle-ware DLLs.

I am currently working on a form that performs several calculations and then submits it to a sql server. I was able to post test data to SQL when using command.CommandText = "<SQL insert statement, inserted values 'test, 5'>" followed by command.ExecuteNonQuery(). But now when i try to submit data using variables i get an "A first chance exception of type System.Data.SqlClient.SqlException' occurred in System.Data.dll"I am not a programmer, so sorry if my code looks a bit rudimentary...

Is there another way to easily make a POST request in .NET other than the WebRequest class? I have a very, VERY small piece of data I need to post: password=theword but WebRequest randomly, and I mean randomly, drops the data when posting to my server. I've tested it by using a chunk of code from my server that dumps the request to a console, and I can that the client is sometimes sending and sometimes not sending the POST data.The code that I'm using that uses WebRequest works in another project, when talking to IIS. The server being talked to (a minimal web server in another system) responds properly every time I POST data to it through Firefox. I've got a function in the same project that fires off a GET request, and that works. It just seems like my POST function isn't completing the transaction...something I've noticed in the past when asking WebRequest to handle small strings.[code]

I have a form which contains a fairly large number of values. I am currently submitting with a POST method, but I wish to convert this to do it with jQuery via AJAX. I have been experimenting with converting my code-behind "save to database" function into a Web Method. I am using a two-step function method, firstly preparing all the variables from Request.Form("parameterName") and then passing them all into a "saveData" function as follows:
[Code]...
From the post mentioned above, I can see I can send this string, but how do I process it server-side when recieved? The article implied that HttpContext.Current.Request.Form("parameterName") should work, but it doesn't... I'm guessing because I need to access it from the txtQuery variable..

this is not really a code issue, more of an events issue with objects. I want to be able to generate an output as the user inputs into each text box under the "further invoice details" section. For example, if the user inputs a value to amountrequired text box. Then a gross total is auto generated without the need to click a button.

If I use byte() instead of long, then i get ExecutionEngineException Exception.

I'm trying to write a vb.net application that works with a 3rd party application called FuzzyTech. Unfortionalty FuzzyTech is quite old so the only way I can interact with it is buy using DDE. FuzzyTech acts as a DDE server. After a bit of research I found a library called NDde which enables me to use DDE. I understand that vb.net does not natively supprt it as it is an old technology.
Now fuzzyTech seems to only respond to the DDE connect and pokes when in debug mode. The only way I can find to get the program in to debug mode is from the menu bar (Debug > Interactive). So I have written an application that runs fuzzyTech, grabs the window and then accesses the menu to put it in to debug mode. My code can then use DDE. I have all of this working ok (although it does feel like a bit of a hack). The problem is I don't want users to be able to see this happening.
I want fuzzyTech to be hidden.After more research I found I could hide the window on startup by using fuzzypProcess.StartInfo.WindowStyle = ProcessWindowStyle.Hidden. However when I do this my code to grab the window and send the menu commands then fails. I think this is because the window title becomes blank when hidden.So I need to know a way of controlling the program after it is hidden or hiding it after it is in debug mode. This is where I am stuck. I'm very new to programming and this has got me completely stumped.
Here is some of the code I am using:
Private fuzzypProcess As Process = New Process()
Private Sub LoadFuzzyTech()
Try
fuzzypProcess.StartInfo.FileName = projectPath & projectTitle & ".ftl"

I'm rewriting a legacy application in .NET. In the earlier version, I used a few control .INI files that could be edited by the advanced user to provide variation in certain program options. (The program also permitted override of these same variabes via menus and such.) I used the API functions to read the .INI files and rewrite them to alter the user's environment for subsequent runs.

I am trying to read data from an external device using MSComm control but the problem is I am getting wrong data. I am recieving 1 byte data but the first three bits are wrong so anything greater than 31 sent from the external devices is recieved wrongly. eg. if I am sending 63(111111) from the device then the input from MSComm control gives me 159(10011111).Due to this reason I tried SerialPort from .Net framework and was surprised to see that it is working properly.
