I have just started coding my Computing project for my A-Level, and I will admit, I am far more experienced in VB6 than VB.NET (as embarrassing as that is to say).I get extra marks for making everything presentable, so was wondering if it was possible to add icons into .NET buttons. For example if I have a button to add an entry to the database, I want a nice Web 2.0 looking icon (for which I already have) next to the text on that button.
I have been given the prep material for my AS Level (Year 12) computer programming exam based around dice cricket. Written in VB 2008.
In the exam we are supposed to change bits based upon the scenario. The scenario and skeleton code are attached.
I have looked through the code so far and made some guesses to what I think may be on the test:
[code...]
if there is anything I am missing which they think I could be asked on the test. I then have to go away and figure out how to program.
So by asking on here, I am not trying to find out coding answers - I do want to figure that out myself. I just want to see if there is anything else I possibly could be asked?
I'm not looking for anyone to complete my "home work" assignment for my A-Level computing as I've done this now and I think it's impressive. What I am now looking for is help in extending what I have done and making it better.
History:I have built my application in Visual Basic 2005 Express Edition. It is a Console Application. After filling in the questionnaire the user gets given results and all this information is stored in a .txt document (Notepad). I want the data that is put in to the application to send infomation to the user's e-mail address. I have been looking around the internet and it says it could do it but it needs Outlook express.
I have been writing code fore a rather large project in the past mounts And Im beginning to think about arcitecture of the program... Its just a complete mess. I dont know how to tackle so much code..Its beginning to be impossible to debug.Basically Im doing the following prosidures. Importing several a Excel files and getting the rfrequency data from these files..Displaying them in a litview and a datatable... so you are able to edit them..Doing some calculation and exporting the results back to a xls file.Problem is now that im going to add more functionallity to the program,. What im woundering about is, is there some good unofficial guides on how to program with OOP?
I am making a application to help manage your files and notes on different projects, you can organize your notes, images and videos, However i am stuck on what coding to use to manage the project, what my.settings etc.
i hav a problem in building a solution in vs 2008.I'm opening vb.net project in VSS repository.When i tried to build the application its giving lot of compile error.After examining the code i've found that the namespaces are not imported in *.vb file , hence the types used in the file are not accessible .I know that we can import namespaces at application level
I am getting a project-level conditional compilation constant error while trying to build my vb.net project. It reads:
project-level conditional compilation constant 'VB_VER=9.0,TARGET="exe",CONFIG="Debug",_MyType="Console",PLATFORM="AnyCPU",DEBUG;^^ ^^ TRACE' not valid: Character is not valid.
I recently upgraded it to the latest version (from 2.0), and I have a feeling that this has something to do with it.
But if I want to use the Project Properties, Reference tab to select a namespace to allow a project-wide setting, is it possible to alias that namespace?
I am coding an asset management system for telecom as my major project.It features submitting asset information,retrieving an asset information by entering the id of the user responsible for it,checking the number of live,stock and scrap assets and downloading it in an excel file and updating any asset information if needed.It has an admin login to it and even a change password form.
I am about to commence coding (actually recoding) on a project that accesses 100 tables of a database, more to added at later time. About half of the accesses are queries with joins and unions. I am more of a coder to not use wizards such tableAdapter, but code more by other methods. I have read some post of this site that suggest avoiding tableAdapters, not to use them in an Enterprise environmentl, but no reasons. I would like to hear from willing to bend my ear, pro or con.
I have a Web Service Application Project in Visual Studio 2008. This is supposed to be an ASP.Net 2.0 project and at some point this has been rebuilt using 3.5.VS has kindly added in project level imports to System.Linq and System.Xml.Linq, but when I have re-targeted the project at 2.0 these project level imports have remained.Because the Web Service Application Project does not have the detailed window for editing project references I cannot find how to remove these project level imports.There is no .proj file which is where I would assume these were included.I cannot now build the project as it fails, even though I only get warnings (no errors reported) such as this:Namespace or type specified in the project-level Imports 'System.Linq' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases.
I am creating an Excel add-in written in VB.NET. I would like to bind KeyDown and KeyUp events to the spreadsheet to record when the user presses and releases the arrow keys while navigating the spreadsheetIdeally, these events would be built into Excel alongside the native SheetActivate and SheetSelectionChange events, for example. Alas, they are not.
I really like the coding speed that vb.net provides, but I don't like the possibility to forget to declare variable types, return types of functions, etc. and that is why in each class I use[code]..
Is there a way to define those two options on the project/solution level?
I've started to use a Vista machine for development. In case it is significant: I'm using MSBee so that I can code in the Visual Studio 2005 IDE while still building against the 1.1 framework.On the Vista machine, when I tried to build a particular vb project, I got this error:
error BC30464: Namespace or type'Compatibility' in the project-level Imports 'Microsoft.VisualBasic.Compatibility' cannot be found.
The same project built fine on my old XP machine. I checked in this folder on my Vista machine:
C:windowsmicrosoft.netFrameworkv1.1.4322
...and sure enough, "Microsoft.VisualBasic.Compatibility.dll" was missing. So was "Microsoft.VisualBasic.Compatibility.Data.dll". Copying them from my XP machine to my Vista machine allowed me to build the project successfully.I'm just a bit puzzled as to why this happened. Why was "Microsoft.VisualBasic.Compatibility.dll" missing? I'm also not very comfortable with my chosen solution - copying the DLL manually. It works, but surely there must be a better way.
I have created a simple program which uses a two tier structure of SQL Tables.At the top level, one record holds the date of the activities and linked to it using its primary key as a foreign key, three subordinate tables hold time stamped records.The issue I have been unable to solve is that before adding any of the lower level records for a given date, a newly added top level record must be saved to the database.Doing this manually is simple - but can I rely on my users to remember to do this before they start plugging in the lower level data?I thought not, so I am looking to save the top level automatically.I've failed miserably but I refuse to believe that it's not possible.
Say we have a DataGridView on the main form. I can chose to establish its properties by code or by selecting them in the Properties panel. Is there a difference between these two techniques, a loading time penalty in any of the cases especially?
I love to experiment with linqpad, but now my task requires heavy computing power. Trying to do it on my computer is painful. My friend has a much more powerful computer than I -- can I execute some operations from my linqpad on his computer? I don't have RDP access, but I can run any .NET program on his computer.
If it is not possible, then is there any FREE service that provides computing power? Maybe a hosting trial or something. I know that Windows Azure offers a 30-day trial, but it has a very slow CPU module and in my country, MS partners cannot be expected to fix service sites when they go down.
I need to compute the percentage of games won and games lost. I keep getting errors and it's driving me up a wall. I've changed my code so many times that I don't really remember what it was like when I started.
Private Sub btnPercentage_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPercentage.Click Dim team As String
How would you take a numerical input from 10 text boxes and total it up and send it to a label. Then average the 10 numeric text boxes and send it to its own label. I am not asking for any code, I just need a hint or two to jog my memory. If this is not clear for you, I'll provide more detail.
I am using SQL EXPRESS EDITION 2005 and Created mdf data file using vb.net 2008. now i want to use this datafile in lan. i modified connection string "Data Source=.SQLEXPRESS;AttachDbFilename=ServerDataData1.mdf;Integrated Security=True;User Instance=True;Connect Timeout=60"it is showing security info error i want to use single database file for my application please help me with connection string. thank you
i am trying to make a robot that i can talk to(not yet) and tell it to goto places 1st task it to figure out how to use an inbuilt webcam in my net book and do an image Recognition for walls stars eg 2nd task is to see if i can get it to use my server to help compute the images because my net book is very slow 3rd is speech to text now can all of these be done in vb.net?
I have multiple level of For Each and in each level, i have a Linq that is the 'In' criteria as in:
[Code]....
It will go inside each for (because the value is not nothing), however, it will only loop (next) in the very inner 'For Each t In tFor'. After it is finish inner loops, the outer Fors' or Next will not execute... even thought there are more than one values in that 'In'... like 'sFor' or 'fFor'. i've noticed while debuging, while break at the for (for example 'sFor', before stepping in), i get the error message:
"Enumeration yielded no results" when i expand the result for that variable and it will not step into it. but if i do not expand the result, it will step in. It seem that some how, once an element is accessed for that 'In' collection, it breaks (meaning does not loop for the rest of the elements) the next for that collection is this a bug or am i missing something in Linq? BTW: i believe it has something to do with the SqlDataReader in the Linq. I'm working with IAsyncResult.
I've had experience with using hashvalues from String objects. E.g., if I have StringA and StringB both equal to "foo", they'll both compute out the same hashvalue, because they're set to equal values. Now what if I have a List, with T being a native data type. If I tried to compute the hashvalue of ListA and ListB, assuming that they'd both be the same size and contain the same information, wouldn't they have equal hashvalues as well?
Assuming as sample dataset of 'byte' with a length of 5 {5,2,0,1,3}
I am trying to write code to compute the Efield on a point P in both the x and y direction, from a charged ring. double y_eField = (_ke_value * _dq * (Sin_angle) / (Math.Pow(r, r)));Problem I am having is the code seems to follow the equation as given but the result it outputs is not correct at all.
I have a server that runs a thread that computes some data through function X. Then I have a client that communicates with the server and gets results from function Y. Now, both function (X and Y) share a common variable lets say varZ. When function X populates varZ when the thread starts on the server, the results are not propagated on function Y when accessed by the client through Remoting. But on the server side the results are correct in function Y! It's almost like when client calls function Y, it has no idea what is happening varZ is as far as the value set by function X thread in the server.
trying to understand DataGridView. I can sum columns with no problems and place the result in a textbox. My problem is multipling two column rows and saving it. I receive the following error when I go to save it. "Column mapping from source column failed because the data column is a computed column. So can I compute two column row to a third and save it, if so how. My code is below:
i made application for computing totient function but it doesn't give me any result this is a code Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
