I'm currently working in .NET 2.0 Visual Basic. The current project is an Active Directory Wrapper class library within which I have a Searcher(Of T) generic class that I wish to use to search the underlying directory for objects.
[Code]...
In short, I want to offer some kind of Expression feature to my users, unless it is too much work, as this project is not the most important one and I don't have like 2 years to develop it. I think that the better thing I should do is to write something like CustomExpression that could be passed in parameters to some functions or subs.
My coworker needs me to write him a regular expression for his vb.net app.I do not know vb and he does not know regex.The regex he needs is:/.*web id: ?(d+).*/iBasically he needs to search a string for something like "web id: 345" or "web id:2534" and retrieve the ID.He took what I gave him above and was able to put this together:
Dim strPattern As String = ".*web id: ?(d+).*" Dim strReplacement$ = "$1" GetWebId$ = Regex.Replace(LCase$(strNote$), strPattern$, strReplacement$)
First I'd like to say I am not fluent in Visual Basic, I down loaded Express 2008 and have easily completed the first few lessons. I have some programing exerpience. I have written a few simple programs with Autolisp for Autocad.Vdraft will only integrate with full blown VB programs. So, Maybe someone can write a simple program using Vdraft api which can be found at :
I'm trying to write a fraction expression on a picturebox, ExpressionBox, placed on the form at design time
Using gr As Graphics = Graphics.FromImage(ExpressionBox.Image) gr.Clear(Color.BlanchedAlmond) gr.DrawString(Expr(0), NormalFont, Brushes.Black, 40, 0) ' numerator gr.DrawString("Kapp=", NormalFont, Brushes.Black, 8, 13) gr.DrawString(Expr(1), NormalFont, Brushes.Black, 40, 24) ' denominator gr.DrawLine(Pens.Black, 0, 20, 300, 20) End Using
The exception occurs when the code is entered. I've used similar code elewhere in the program without problems, so why is this exception occurring here?
VS2010 VB.Net Windows Form (not WPF). Any Hello World level example for printing the text within a multi-line text box they can post? Ditto for a print preview? I need to write a simple envelope printing app and I need a good base to build upon.
I have a program with various settings, all stored in the app.config file. Often, I have a need to edit the connection string setting. I cannot do so using the My.Settings.myConnectionStringVariable method, as this is read-only. What I would like to do is have a big text box, and simply load the entire app.config file into it. The user could modify whatever they wanted, click save, and the program would save the new edits to the app.config file, and restart the program. I don't have a huge need to only pull out the connection string, as getting the text for the entire config file would suffice. However, if it is easier to pull out just the connection string from the config file, that would work too.
I've build a large program with many references. F.e.:
System.Data.DataSetExtensions System.Linq.Dynamic
I've to write a Dynamic Linq Expression: [URL]
In my case: Dim query As IEnumerable = ds.Sales.Where(strWhere)
But with System.Data.DataSetExtensions Where is misinterpreted. The compiler expects (Datarow, Integer, Boolean). If I delete System.Data.DataSetExtensions everything is ok with this expression, but I get many other errors, so I need this reference. What can I do that the Where is interpreted correctly?
I'm not sure if this is possible but I would like to associate a class name reference to a shared member method / property / variable. Consider:
Public Class UserParameters Public Shared Reference As Object Public Shared Function GetReference() As Object
[Code]....
In another part of the program I would like to simply call UserParameters and have it return Reference either by aliasing GetReference or the variable directly.
I am trying to emulate the Application, Request, or Session variable: Session(0) = Session.Item(0)
I'm currently trying to write a really simple game on which the player has to pursuit some figures on the screen. Since i'm just writing the prototype version i'm using a Panel wich i redraw 1000 times per second. Now, i want that every level is similar but not the same as past level, so i created a Level Class that contains the game objetcs of Player Class and the Figure Class, wich are the ones that have all the movement subrutines. So, with a Timer, 1000 times per second, i get the input from a joystick, pass it to the player objetc and update the position of the figure object. All this stuff is reported to an internal Panel that every level object has, wich i refresh and then pass it ByVal to the panel that the player actually sees. The problem i have is that after the first level ends, when the second level starts running, i can see the last frame of the fisrt level flashing behind the figures and it makes the game run a bit slower after every level. I tried keeping a copy of the inicial state of exterior panel and use it to clean the one i'm using on the levels but it didn't work...
I am trying to write a simple program which will simply have buttons to open spreadsheets, and a search facilities to look for spreadsheets with a title which is an invoice number. I have my basic forms layed out, all a need now is help with the code.
I am using Visual Basic 2008 Express, and just need a line of code for a button to open an application/spreadsheet. Also, is it possible to have a search box open a file automatically?
I recently started working with Vb.net and I am just trying to create a class that has two properties one is StoreName and the other is StoreImage. What I am trying to do is figure out how to create objects using this class? Each object will be a Store that has a corresponding Name and Image to go with it. Here is the code I have written so far although I am not sure if im headed in the write direction with the function. Also not sure if it matters but I am using ASP with VB?
Imports Microsoft.VisualBasic Public Class Store Dim NameofStore As String Dim ImageofStore As Image
VS2008 VB.net. I have a simple Product Class with 20,000 records: Product(1).partno = "3999399" Product(1).desc = "Bearing" Product(1).loc = "34"
This represents ONE sale only and may appear in 100's of other records Using LINQ how can I: Determine the total count of each partno and then sort by descending order
Example: Count Partno Desc Loc 3,232 3999399 Bearing Loc 34 2,323 3899388 Bushing Loc 35 etc.
I'm trying to make a simple Class that reads data from a SerialPort.The Device returns a number of lines of Strings.[code]However running this code in a Form with one TextBox Control (txtLog) Allways results in the "The operation has timed-out." Exception.[code]
I need to print a simple receipt to my EPSON-TM-T88V thermal POS printer with VB.NET 2010 on XP (eventually to run on Windows embedded POSReady) via USB.All I need to print is some text and a logo. I have my logo stored on the printer. So, I need to use Epson's ESC/POS commands. So, does it make sense to use Microsoft.PointOfService? Seems like a lot to go through to send some escape sequences to a printer!Apparently, the PointOfService system has not been updated to work seemlessly with VB.net 2010 (details below) That is why I wonder if I am taking the wrong path.IF this is the right path...here is what I did and where I am stuck.
For people trying to us the PointOfService classes in VB 2010:First you need to download and install the POS.net (Microsoft.PointOfService) - free download MS. Then you need to add references in your vb.net project. When you try to run it, you will probably get an error something like this:
{"This method explicitly uses CAS policy, which has been obsoleted by the .NET Framework. In order to enable CAS policy for compatibility reasons, please use the NetFx40_LegacySecurityPolicy configuration switch.
I'd like to write a simple Windows form that will make it easy to record a voice message before uploading it to a remote web server and sending the URL to the recipient(s):
[URL]
Currently, the user has to use Sound Record to record the message, use an FTP client to upload it to a web server, and finally, use an e-mail client to send the URL. I'd like to combine those three features into one.
I decided to make a simple temperature converter (C to F vise versa) for class since I already had made a calculator. But for some reason, it won't work because it can't convert from string to double. How do I fix it?
I have a simple class that I trying to populate from an XML document. The XML file has an attribute called TrackingID in the root node which I would like to get as a property. For some reason, when I deseralize the class, the TrackingID is null. Everything else populates fine. I have tried various attributes on the TrackingID property with no luck.
I have to write a program that uses a class...and I've got no idea what it is or how to do that.My program is a simple interface that adds up the users selections and quantifies them into a membership fee.
Code: Public Class Form1 Const FamMem As Integer = 90 Const SigMem As Integer = 50
I got all C# implementations on Google, so I converted it to VB.Net, but I am not able to convert 1 line where it gives error.My Class :
