I figure I should use 'Aggregate' but apparently I am getting it wrong First I get a list of my Entity objects Dim employers As List(Of myEntity) = (New XXXX()).getZZZ(userName, userType) Then I figured this would be a way to put all the names in a string Dim names as String = employers.Aggregate(Function(current, [next]) current.Name & " " & [next].Name)
I'm suppose to end up with a label box with my name spelled out in it using string manipulation. This is suppose to happen using the concatenated string to output the name into the label box. I don't have any error codes but I also don't have my name in the label either. [code] "Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. [code]
For my application, there is a login form in which users have the option for it to "save the login information" Kind of like MSN or other websites in which you go to a login page an the information is filled out. On my login form, I am using this code for my checkbox which is to "save login info"
Private Sub CheckBox1_CheckChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox1.Click Dim s As New System.Text.StringBuilder
I am writing a tool that logs stats for a first person shooter game. The game writes its information (including who killed who with which weapon) to a log file, which I read every so many seconds and parse so that I can write that information to a database.I am now having trouble parsing the weapon out of that string of information.
Some additional information is required: a weapon in this game can contain attachments (such as a scope, a grenade launcher, etc). Weapons can have either 1 or 2 attachments. Some weapons however cannot have any attachments at all.
Each log file entry that describes a kill contains a code that describes the weapon that was used. This code is a concatenation of either 3 or 4 parts:
<weapon>_<attachment>_mp <weapon>_<attachment1>_<attachment2>_mp where <weapon> is a code that describes a weapon and <attachment> is another code describing the attachment.This should be easy to parse by just splitting along the underscore characters, but there's a few catches:
1. Some attachments are able to kill players as well. Specifically: grenade launchers, flame throwers and underbarrel shotguns. In this case, the attachment is listed before the weapon:
<attachment>_<weapon>_mp Note also that in this case there is always only 1 attachment.
2. The biggest catch: some weapon names have an underscore in them (some even have 3 underscores)! So simply splitting along the underscore won't work in all cases; if the weapon name contains an underscore I'm splitting the name of the weapon..This makes the list of possible combinations a lot longer. The ones I can think of (I think these are all):
I have a dictionary that I want to access with a key that is the combination of a string (AcctNum) and a date (BalDate).It seems to me the simplest approach is to create the key by simply converting the date to a string and concatenating:MyKey = BalDate.ToString & "|" & AcctNum
I know I also have the option of creating a composite key by writing a separate class and overriding GetHashCode() and Equals() a la this solution. To me, the concatenated string is a simpler, if somewhat less elegant, solution. Am I missing some compelling reason why I should go with the composite key class approach?
This lookup is the crux of the project I am working on, so performance is my main objective (with readability a close second).
I'm creating a text box with auto-suggested. So, it works well. It suggests only first name, but I want it to suggest the full name (first and last name which two different columns). Take a look at the following code behind that worked as expected :
I have a form where a number of textboxes are programmatically created within a flowLayoutPanel and named by adding together 2 strings.
With the click of another button i hope to have all the values entered into these text boxes stored in a text file. However, i cant seem to find a way to add strings together to allow me to retrieve the values entered within the text boxes created.
Below is the code i have so far: BTW FLP is my flow layout panel and c is my calculated nmber of textboxes that are created.
Private Sub createTB(ByVal c As Integer) Dim x1 As Integer = 1 Dim y As Integer = 2
I'm trying to code a program but this error repeatedly shows up and I can't for the life of me figure it out EValue of type 'String' cannot be converted to 'System.Windows.Forms.TextBox'. It appears in relation to this code
My aim is to have a textbox in which a page of information is already written for the user to read. This box will have a vertical scrollbar, so I can't simply superimpose a button over the textbox. What I would like is to be able to have certain words underlined and in a different text colour (similar to a hyperlink), which, when clicked, will throw up a pop-up box.The purpose is to create a glossary such that if a new word is used in the textbox, I can allow the user to click on it
ive been trying for days to try to figure this out out on my own , and im wondering how i can have the user enter a string into a textbox and press a button and have that text appear on a label.
My user wants to have textbox fields that don't have any masks but wants those text fields to reformat any text that is entered as mm/dd if it is a real date entered. They won't be using the year.
I am trying to build a user control that will do exactly what the SQL 2005 Connect to Server interface do, eventually create a connection string and store in a app.config file. It should allow user to select server type, server name, authentication, user name and password. It should also automatically load available servers and domain login by default.
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?
sqlsub = "SELECT distinct field1, field2" sqlsub += " FROM tbl I Dim da As OleDbDataAdapter Dim lsdataset As New DataSet
[code].....
My prob is how should I bind the combo with field1+"("+ thpr+ ")" thpr is the string i get from function by passing field value 2 from query my combobox should be displayed as field1 + (thpr).
Following code sample should concatenate the value. Concatenated value has to be assigned to variable AlphaStr. But result is always null in the variable AlphaStr.
How do I display the concatenated records in my combobox? I have the following codes
Private Sub frmAssignSubjects_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load If cnn.State = ConnectionState.Closed Then cnn.Open() If rdoHS.Checked = True Then
[code].....
What should I put in the DisplayMember and ValueMember? If I will not concatenation, I just use "LastName" and "IDNO" in my DisplayMember and ValueMember respectively then records get to display in my combo.
I am writing a program for my A-level coursework But for some reason I got this build error this has never occurred to me before, I have no idea why I can't use string for the name of my form.
Dim Selvk As New Selvkost2 Selvk.PassedText = TextBox29.Text Selvk.Show()
[code]....
in my second form and the text passes. but I need to pass values from 20 textboxes. do I have to copy the code in my second form 20 times an declare passedtext2 and so on or is there an easier way to do this?
I am creatting an windows application software in which many controls like Buttons, textBox, combobox are remain same in 12 different form. In this 12 diff form the activity of those controls will remain same.The scenareo id
1. I have 12 forms.
2. Each form containing 3 labels (Country, State, City). These labels indicates 3 combobox from which we can select location.
3. Now I need to use these 3 controls in all 12 forms with same activity.
4. When I change forms to another, these buttons shud remain same.
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.
