Make A Settings Field Points To A Constant?
Jun 27, 2010
I would like to make a Settings Field (SKey) to point to a constant (Q)
Where the Settings Value will be modified by the user using Text box and public const Q = keys.Q so I can let the user modify a hotkey to what ever he wants I wished to use the following code for registering the Hotkey
Public Const Q = Keys.Q 'My.Settings.SKey should points to this variable
'There will be more constants for other keys
RegisterHotKey(Me.Handle, 1, HCtrl + HAlt, My.Settings.SKey)
the problem is:
the program use MY.settings.SKey as String and I cannot define it as integer where the input is a text

I've come across a very basic problem which I'm sure has a basic answer.Forgive me but I haven't programmed in years and this just a hobby of mine..My problem is that I need a drawn object (say an ellipse) to move to the cursors location when I click. Imagine an adventure quest style game where you view your character in birds eye view, and it moves according to where you click on the map.I can draw the image fine, and move the image around fine - it's more so the formula I'm using which I'm a little stumped on.I have certain requirements though.
1. I need a timer that constantly updates the drawn object's (lets say character from now on) location. Each tick will essentially be the character taking 1 step towards the cursor's location.2. At the end of each tick of the timer, it'll will invalidate the form/control to invoke the paint event, and of course, the objects location will be be updated.It sounded simple enough to create a linear equation based on the objects original location and the location of the cursor when I click.However, that will not give it a fixed speed.If say for example, the gradient (rise/run) between the cursor location and objects location is very steep, the object's y-velocity will be greater than that of the x-velocity

There are lots of questions about this but I've not been able to solve my problem using the answers to any of them (after many, many attempts..)
I'm working in vb.net creating an asp.net web application. I have an SqlDataSource and a GridView on my page.
I want to change the DoNotMail boolean value represented by a Gridview checkbox and automatically update in the database if the checkbox is checked from 0 (False, Will Mail) to 1 (True, Won't Mail) here is the code I used. [code]...
is it possible to do a two way sync on the entire gridview when the user hits a button so you don't have to do an update every time a row is changed? because the user might check the box and then check another box then uncheck a box and it would be a lot of updates...

When building a class library which contains many classes, all classes uses a lot of common constants and functions, what is the best to do:
1- Declare these constants and functions as public in a module.
2- In each class declare constants and functions used by individual class as private.
The first choice is good for easy and fast implementation, but re-using a class in a different project will require importing the module to the other project.The second choice require a lot of copy/paste for code snippet but a class can be re-used in different project easily.

look at this picture of my index form. It's resized, now you can't see the full labels text.
Example: under the first cover, there stands "Hardbass Chapter" and accetly it is "Hardbass Chapter
21 (2011)". It's not a problem that a peace cut off, but, I want to make that clear to the users,
with adding some points.

Is it possible with VB .NET to make the program use specific regional settings? More precisely , I want to make my application always use the English regional settings (those defined from Control panel > Regional settings) in order to always use (and calculate) the decimal numbers by using the dot symbol ( . ) as decimal separator , regardless the settings on the current PC (in order to avoid forcing the user to change his Regional settings) ?

Ok, so here is the problem. I need to pad the ID field to a length of 10 to make the display in the list box look right. I also only need to display the ID, last name, first name, and middle initial. I have no idea how to implement this in to the code. I included the studentList.txt if anyone feels inclined to run the program.

I have a field called PODate & TextBox txtPODate.text. It saves/updates fine when the txtPODate is filled. But when the txtPODate is blank, it throws an error. The problem is that I can't enter date for each record unless I got Purchase requisition converted into Purchase Order. Once it is converted to PO, I need to enter the date to update that filed. So, how can I make my program to accept blank date field.

I am a bit new to crystal reports even though I've been doing a bit of heavy lifting with it.I have this crystal report that has a datetime field.This field has a default datetime of 1753-01-01 00:00. Now I want this field to display only date like "01-03-2011" and also anywhere it sees the default date, it should display an empty string like To achieve this I used this formular (in the display string)
if CurrentFieldValue = DateValue('1753-01-01 00:00:00') then
''
else
totext(CurrentFieldValue)
This successfully changes the default date to empty string. But now I can no longer change the format to dates only.

As you can see I was playing with WithEvents but that didn't seem to help. In the above code all I was trying to get was some kind of reaction to the clicking of a checkbox - but nothing happens (no errors, either).
