View 3 RepliesI've run into another road block while programming my game. The problem is that when a player types North in room "Crash Site" They get the description of traveling to the next room "In Trail" as well as the description of traveling to the next room after that, "Deeper In Trail" before having to type north again. I've looked over the code several times, but can't find the problem....the conditions seem to be fine, but I'm guessing that's where the problem is..
Code:
ElseIf LCase$(txtInput.Text) = "go north" And Room = "Crash Site" Then
Room = "In Trail"

create a chat room? My current hosting is a linux server with mysql. I want to make a client that can connect to the database.(already done) and if the user exists, to open a chat form. I want this to be multithreaded, that way I can have up to 500 people chatting with each other at the same time, from different locations. (realistically will usually be around 50)I have found some winsock type examples, but I dont understand how I can adapt that to work with a linux server... Can anyone help give me examples? I guess I basically want an IRC.(Which I dont know how to implement.)

View 2 RepliesI am developing a hotel software product, and one of the features required is to be able to display the room numbers in the hotel, and then the status of them for each day of the month.
I am trying to create something similar to a DataGridView control where at the top the column names are the dates of the month, and to the left is the room numbers as rows. Please see the below screenshot of the function I wish to have. However I do not know what control or function they use to create this grid below (it is from an existing product). I need to not just be able to join multiple cells together when it is the same person in the room for multiple days, but also allow drag and drop ability.
Currently I have a DataGridView control and am able to simulate the below screenshot, however with a datagridview control I am unable to join cells across multiple columns nor allow drag and drop ability between rows.

I have changed my application. Now it has two separate datagridviews each using the code above (seperate bindingSource and GridView). One each in it's own splitcontainerpanel one above the other. My intent was to allow the user to view both at once or grab the divider and slide the panels up or down to only reveal the grid they want to view.Trouble is, when one grid it completely collapsed I get an error "No room is available to display rows".
Is there any way to build a web based chat room application by using VB.NET as behind code and put it with ASP.NET on the web so users can login the account and start to chat without keep refreshing the browser or frame and have a real time transaction, I know that I have to use .NET.Socket namespaces, but don't know exactly how. I have seen many examples of windows based applications, but I need to know how to put it on the web.
View 5 RepliesI'm trying to make a carpet calculator that will do the following:
1) How many metres of carpet are needed to cover a room.
2) How many rolls of carpet that will be.
3) How much full-width carpet will be left on the last roll.
The carpet is supplied in rolls that are 5 meters wide and 30 metres long. Any excess width is discarded. This means that rooms that are wider than 5 meters need several strips of carpet. The smallest space that will be carpeted is 1m x1m, the biggest is 20m x 20m. I only need whole meter lengths, so example if only 1.6meters of carpet were used to cover a room it would be rounded to 2 meters.
Here's the code that's giving me incorrect calculations. The number of rolls required to carpet the room seems to be the biggest miscalculation.
Private Sub btnCalculate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalculate.Click
Dim width, length As Single 'Defines variables.
If IsValidInput(txtWidth.Text) Then
width = txtWidth.Text

How would I create a multi-tcp chat room. Im having trouble handling them. I know you can store the connections as arrays or store then in hash tables. Is there a better way to data to a specific connected client. My way was to just broadcast the message to all the connected with the clients name (EX: Client1||MessageHere) || is the split. The client reads the message and sees if client name matches if it does then it will display it other then that it will not. I found out that my server was sending out useless data with this method. So is there a better way to handle/Send messages to a specific client?

View 2 RepliesSilverlight project with tabcontrol hosting canvas objects. I want to wrap my entire tabcontrol with a scrollviewer so that on a short display you can scroll vertically to see the whole area on my canvas.When I run my project my scrollviewer vertical bar is always showing even when there's more room vertically than needed for a scrollbar.
All I am trying to accomplish here is a min resolution of 1280x768 to be scrollable and anything bigger than that have the scrollbars hide. My laptop is only 768 tall, but my canvases were developed with 1280x1024 in mind. So I would like a way to set this up so that everyone can scroll or just see the canvas all at once depending on their resolution.
Anyone have any ideas why it is always visible? I've tried setting canvas width and height. I tried setting stretch on alignments on the outer grid. Saw both those tips while searching other issues similar to mine.
Some code:
<Grid x:Name="LayoutRoot" MinHeight="768" MaxHeight="1024" MinWidth="1024" MaxWidth="1280" Background="#FF6A6868" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
<Grid.ColumnDefinitions>

View 1 RepliesI have created a hotel booking system programme. However, I am puzzled as to how when the booking button is clicked it can search a database and find the best suited room (RoomType) and make sure that it is available (Date of Departure < system.date).
This data is held in two tables (Access):
Booking:
BookingID (Primary Key)
CustomerID (Foreign Key, Table:Customer)
Date of Arrival (Date)
Date of Departure (Date)
RoomID (Foreign Key,Table:Room) Room:
RoomID (Primary Key)
RoomType (Text)
RoomPrice (Currency)
Floor (Number)
This has all got to be done within a single button click. Any ideas as to how I can place this into my vb code?
I have a rough query for picking a room that is best suited:
Code:
SELECT roomID
FROM Room INNER JOIN Booking ON Room.RoomID = Booking.RoomID
WHERE Room.[Room Type] LIKE '" & Room_TypeTextbox.Text & "'"
AND Booking.[Date of Departure] < Now()
I have been trying for a while to get it to select a single matching record as there is a high chance that this query will return multiple records but im unsure on how to deal with that.
"No room is available to display rows." (VB .Net)
I am getting above exception when trying to set the grid property "FirstDisplayedScrollingRowIndex".
Form1 and Form2 are MDIchild form. Form1 has a datagridview, and form2 has a command button. On click of the command button the grid gets populated and everytime I click, certain number of rows get added to the grid at the end. After populating the grid i am trying to set the scrollingindex to the first row of the last set of rows added.
When form1 is closed or open and i perform the click event, the index gets set properly without giving any exception. But when I minimize form1 and perform click event, i get exception "No room is available to display rows." is getting diaplyed.

View 7 RepliesI have a panel wich inherits from FlowLayoutPanel. I add a lot of picturebox to it. I allow the user to navigate through them with arrow keys. Since I have a lot of PictureBox, most of them doesn't appear at the visible rectangle of the panel. I want this panel to scroll to the selected control when user selects it. For select a PictureBox I made a class wich inherits from it and override the OnPaint sub. I also have a field m_selected to determine whether the PictureBox is selected or not. On OnPaint sub if this field is set to true, I draw an orange border to notify the user that this control is selected, otherwise I draw a simple black one. In the panel I also have a m_currentsel field to save the control wich is actually selected. When user selects a control this field contains the selected control.
