Move A PictureBox Produces Incorrect Results?

Feb 17, 2011

Im working on a board game in vb.net. But Ive stumbled on a problem; for some reason Im not getting the correct location reference when I move my picturebox. Let me explain the procedure; First it locates the current position of Red1 with Red1Top and Red1Left, and assigns a number for its position; intCurrentSpot. Then it adds what ever was rolled from the dice intDieA to the current location; intCurrentSpot and the second case statement moves it to the new location. HOWEVER position 11 reads as position 10 and hence gives the user an incorrect reading to where the dice points. Ive checked the numbers over a thousand times and still getting an incorrect reading, what am I doing wrong or can I use something else to get Red1 location?[code]...

Sending The Same Series Of Emails With MAPI In VB5 Produces Different Results?

Oct 15, 2009

I am using VB5 on a Windows XP SP3 computer.I have an application that send emails to customers that have birthdays today and that bought a product from me today. If I run the application several times with the same search criteria with the same customers and the same date and time, I "may" or "may not" get the save Emails sent out.I am using a MAPI Signon prior to the birthday select and MAPI Signoff after the birthday select; another MAPI Signon prior to the sales today select and MAPI Signoff after the sales today select.I count the emails that are supposed to be produced in each select above and the counts are correct. It's the emails that may not agree with the counts.What could cause this?

Javascript And .net Returning Incorrect Results?

Nov 17, 2010

We are noticing this occurs BOTH in javascript and in VB.net 2.0. So basically both in server side and client side code. Basically if you run this equation 975328 - 153279.43 you get the following answer 822048.57000000007. However, if you run 975328 - 153279.4, 975328 - 153279.433, or 975328 - 153279.5 everything is returned correctly. WHY the system calcuates the 975328 - 153279.43 with an answer with 11 decimal places? Not to mention adding the 7 in the 11th decimal place, thus making the equation answer incorrect.Of course I know I can trim, set the answer to appropiate decimal places, etc., etc.the above is proven by just entering the equation into the immidiate window, thus ellimnating varibables such as object types, etc., etc.

DataTable Returning Incorrect Results In DataGridView?

May 18, 2010

I have been having an issue with returning records from a SQLServer database where the date the record was created is between 2 user specified dates. When I populate the DataGridView with the results, they are incorrect and do not follow any recognisable pattern.

For example, if I specify the dates 05/05/2010 and 12/05/2010 I get the attached data in the DataGridView.

Code:
Private Sub btnGo_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGo.Click

When Save results In A SQL Server Table / They Are Incorrect

Mar 10, 2009

When subtracting two doubles the result appears to be correct but when I save said results in a SQL Server table they are incorrect. I know their are problems with decimal values in the binary world but isn't there a work around for this?For example 421.2 - 418.9 = 2.3, but the result stored in the SQL Server table is 2.29!In the VB code I used Math.Round to round to two digits and the values appear correct during debugging but, as I've said, in the end they are off by .01. [code] decimal(10,2)BTW, I've tried numerous methods of getting the correct value but have not met with any success. I've used Math.Round on Val1 and Val2 separately, after the subtraction, and on the ResultVal. I've also converted the ResultVal to a string using Format(ResultVal, "#####.00") and then back to a number but still the value that ends up in the SQL Server table is wrong.

Click A PictureBox And Then Move That PictureBox With Keyboard?

Nov 11, 2009

Ok, so I have a new challenge for the D.I.C. Heads. I'm making a simple little game using VB controls. I know it's not the best idea in the world but it'll have to do for now!

Here is whats happening. I've created a class that inherits the PictureBox control that I want to use to place my game pieces on the playing field.

Dim pbArmyUnit(0) As ArmyUnit ' ArmyUnit is a Class that inherits Picturebox now I create the playing pieces at runtime as needed and append them to the array. Player currently buys the units and places them on the playing field.

[Code]...

On a side note how can I look at a stack of pictureboxes all created at runtime to determine whats at a particular location? Example. I move my army unit over top of the picturebox that shows my forest. How can I tell what picturebox I just moved on top of? does that make sense? I don't need code for this just directions on looking at the right info so I can figure it out.

I am creating my terrain at runtime as well since it's randomly generated. and I'm basically making an array of 192 pictureboxes with the appropriate terrain image as well as some other modifiers. Just like with my armies above I've inherited picturebox and created a terrain class array, this way I'm able to add my movement modifiers etc, directly to the picturebox I place on the screen. It's these pieces of terrain that I want to be able to check before allowing the unit to move into them! to get movement costs etc.
