Feb 4, 2010How would I check if a key is currently being pressed?
Also how would I detect if a key is pressed without using the KeyDown event. The reason I am not using the keydown event is when the user holds down a key it calls the event, waits a second than keeps calling it. I do not want the wait period if a user is holding down a key.

Asp.net - Some User Controls Not Loading When The 'Back' Button Is Pressed?
Dec 14, 2011I'm working with ASP.NET and VB.NET. I have a page which contains 5 user controls. the page itself does nothing, it just presents the user controls to the user.
The user controls work fine when I come on the page, or when I refresh, but when I go to another page, and press 'Back' only two of my user controls shows up, and they don't work like they're supposed to!
Short description of the controls:
2 controls which look if the user has to create something and shows an option to do so. (goes to the DB)
2 controls show an overview if needed (goes to the DB)1 control looks if the user is an admin (does not go to the DB, but looks in the securityContext)

Let The User Choose A Time With The Numeric Stepper?
Nov 12, 2010I have an application that, when I finish it, will generate a graph of data drawn from a My SQL Database. It's going to be a simple time graph, with time on the bottom and a few stuff on the y axis.What I want is for the user to be able to enter the date. I would like it to be like a numeric stepper. Before I had two numeric steppers in the form but I decided one would be best.The idea was it would be like this: mm:hh [UP/DOWN ARROWS HERE]I saw one that was in use in an actual program. It had it so when you clicked the minutes, it selected the minutes and you could change them. The you could select the hours and change them. How would I do this?
View 2 RepliesAllowing User To Switch From Metric To Imperial When Ok Button Pressed
Mar 3, 2011I am making a program that calculates various results with variables entered by the user. What I am trying to do is incorporate a function that will allow the user to switch from metric to imperial easily but only when the ok button is pressed. Now I got all the coding done for the metric and everything is working fine. My problem is when I use the radiobuttons to switch the entered variable in the text box to the desired unit it gives me a 0 or a random number in the textbox...
I also have labels indicating each variables unit which I easily managed to change with the text box using this code. :
'Change Labels to Metric
lblMDegreeC.Text = "Degree C"
lblMDegreeC2.Text = "Degree C"
lblMmm.Text = "mm"
lblMmm1.Text = "mm"
lblMmm2.Text = "mm"
lblMm.Text = "m"
lblMm2.Text = "m"
lblMm3.Text = "m"
lblMDegreeC3.Text = "Degree C"
I created all the coding to convert the metric variables to imperial. My problem is changing the textbox text when the user switches the units during run time. The labels change without a problem but the textbox never works. I have attached the coding for the file.
Numeric Up - Down Box - Display A Variable That The User Can Choose A Number For
Jul 24, 2011I am using VB .net 2010 express from microsoft. I have a numeric up down box to display a variable that the user can choose a number for. Then I have a text box that I want to display a result of the updown box * 1.5... So far I have the following... What do I need or need to change? I have the integer variables initialized or whatever with Dim statements as follows -
'speed variables
Dim CruisingSpeed As Integer 'cruise speed - updown box
Dim FlankingSpeed As Integer 'Flanking speed - will be cruise * 1.5

View 3 RepliesVS 2008 - How To Store User Numeric Index / Socket Number
Sep 7, 2009I have been working on recoding a VB6 client/server application of mine and have run into a bit of an issue with storing the players location on the tile map which means I will need to rework the way I am storing the user connections. In my VB6 application I would store the user's numeric index/socket number/whatever you'd like to call it as the Key, however, in VB 2008 I can't seem to find where, or if, the numeric index is stored. If this isn't possible then does anyone have an example of how they store user connections using some numeric index as the key of a hashtable?

View 3 RepliesVS 2005 Have The User Click On The Button The Button Stays Pressed While The ContextMenu Shows?
Mar 15, 2010I have a button on my form where I'm showing a ContextMenu when the user left clicks on it, I'm actually using MouseUp right now to show it.What I would like to have happen is the user click on the button, the button stays pressed while the ContextMenu shows, it returns to normal when the ContextMenu closes (Either a menu item was selected, the user hits the escape key or they click/tab to somewhere else). Also I'd like to position the ContextMenu in the lower left corner if the menu opens down or the top left corner if it opens up. So the left edge of the ContextMenu is flush with the left edge of the button.Moreso the button staying pressed until the ContextMenu is closed.
Edit: I'm also ok with this being it's own control inheriting the FW's Button that used the assigned ContextMenu as well.

View 4 RepliesNumeric And Non Numeric Data?
Jan 22, 2010I am reading a data file and storing them in an array of string.Data is random, could be like "1","2","133,18" but sometimes there can be missing values like "?".Once I load the data in the array, I want to check if at least a majority (like 60% of them) are numeric values.If yes, then I wanna track down the higher and lowest value in the array, and output a range of 5.Loop through the array
If 60% of them are numbers (integers or decimals) then find highest value, find lowest value end if produce range
If for example lowest = 1 and highest = 100, range of 5 means 0,20,40,60,80,100 (so 5 ranges are 0-20, 20-40, 40-60, 60-80, 80-100).Also if the ranges turn to have decimals due to weird numbers, I would like to round them up.My problem is, in order to find highest and lowest when there are non numeric values in the array like "?", how should I handle those? I was thinking of something like Double.NaN but I would have to have an array of doubles.
