Jun 30, 2009I'm trying to design a game using vb.net window application, my game is sokoban, a logic game where the character pushes boxes to the destination.I have already programme my picture to be move by my direction key, I trying to find out if it is possible for picture box to push picture box like when the character(a picture box) move to the box(a picture box too), the box will move also. and also the logic for creating obstacle for the game, as the picture that i have programme can move beyond the page, I'm trying to lock the obstacle in, so when i move the picture, it will be block by the picture box.

Manipulating Audio Files With .net?
Apr 2, 2012I need to be able to read audio files and manipulate them from within my own program (similar to how Audacity does it). Now, I'm not asking for something with a thousand effects and such, I just need the minimal as far as audio manipulation for .net goes. I really just need to be able to figure out pitches and frequencies being played at what times and the ability to move them all around.
View 1 RepliesManipulating Data From A Database Within VB?
Apr 30, 2010I'm creating a program that displays data from a Access database in DataGridView, and I'm able to "call" the database and display it in datagridview normally, but I need to be able to take the data from 3 separate columns and average them together, within VB.
My table basically displays 3 grades for a student, one column for the student's name and the other 3 columns for 3 separate grades, I need to be able to take the 3 grades from the same row and average them together, then display them in a separate column within DataGridView.
Here is my code so far, but this only displays all the records without the average:

Manipulating Output From Sql Command Asp.net?
Feb 10, 2011I am building a quiz application which has 5 categories. I am saving details like name, category and score to DB. Table where all data is saved looks like :
Name Category Score
John Windows 10
Tom Mac 5
On the start page i want to disable/enable categories if user has/has not took quiz yet (ie. if John has already completed Windows quiz but hasn't Mac then enable Mac Quiz, disable Windows and show Windows score).Whats the most elegant way of retrieving these values from database and then passing them to variable or boolean? What if search returns NULL (if quiz was not taken by John) and manipulating output from SQL Database? I am using vb.net 2.0 and SQL server 2005 and its an asp.net application.

Manipulating Text In Another Form?
Jun 1, 2010I'm trying to make a program that can handle menu order in restaurant.
In this program, there are Main form (frmOrder), Starter Form (frmStarter), Entree Form (frmEntree), and Dessert Form (frmDessert). Each category (Starter, Entree, and Dessert) contains 4 menus, and each forms other than main form have label for name, price (label), and quantity (textbox).
Main Form have 4 buttons (3 of them opens respective form of Starters, Entrees, Desserts. Last button calculates total), and it has big label that displays all the ordered menu. By default it has current time and date, so any ordered menus are supposed to be displayed on separate line (with quantity, name, and price with dollar sign).
Below is the code I wrote for frmOrders

I tried to see it works, but lblTape.Text (which is the big label that displays ordered menu) do not change. I did saw lblTape.Text got value it supposed to (item quantity & item name & item price) but it doesn't change when I close form and return to Main form. I'm not sure where I got trouble to end up like this...

.net - Manipulating Textbox Variables In Calculations?
Jan 2, 2012I have some code where I am trying to use variables in a tabpage. The first tabpage only has one text box for user entry (miles.text) and a button to do a calculation: traveltime = mileage/speed. The value from miles.text is stored into a variable called mileage while the speed used is stored in a variable called speed (me.speedtextbox.text).
Ordinarily, doing val(variable.text) works like a charm and it's not doing it in this case. When the user enters 100 for the mileage, it should be divided by 65 (the number in the database) and, therefore, the answer should be 1.53 hours. In my case, I'm getting "infinity" and whenever I do anything else with the variable, I get "when casting from a number, the value must be a number less than infinity." But it is! It's only 65 and I double-checked that the dataset said that too, which it does. Not sure why I am getting this error.

May 24, 2010Imagine I have a rectangle say 400px x 300px. All of this is very easy using Sytem.Drawing. DrawImage. But then I want to leave the left hand side as 300px but change the right hand side to 250 px. I can draw the box using 4 DrawLines but I don't know how to squash the image into the new shape. I want the right hand side of the shape to be 250, the left size 300 and the top and bottom 400px.I can't use DrawImage as it expects the left and right sizes to be the same. Is there a way to manipulate the image into the new shape?I've looked at other questions, but they only apply where the left and right hand side is equal.Any thoughts on how to squash an image into a shape which did not have parallel sides?

View 6 RepliesManipulating The Split Function For Two Arrays?
Aug 21, 2009I had a question regarding the split function used in Visual Basic. As of now I have written a function that brings in a string value. The string value returned will probably look like this "List1;List2; Field1,Field2". My goal is to use the split function for this string to put all the lists in one array and to put the fields in another array.
The problem is between where List2 and Field1 are. I don't want Field1 to be placed in the list array. I'm thinking there might be a way to do this by parsing but I'm not sure. Here is my current code below.
Dim s As String = GetSetting("ReOrderList", properties.SiteId)
Dim affectedLists() As String = s.Split(";")
Dim affectedFields() As String = s.Split(",")

VS 2005 - Manipulating Excel From Console App
May 5, 2012I'm setting up a console application that ...
1. Executes a stored procedure that populates a SQL table for reporting purposes.
2. Opens an Excel Workbook.
3. Refreshes the Workbook.
4. Saves the Workbook.
5. Closes the Workbook.
6. Sends the Workbook as an attachment in an e-mail using the SmtpClient class.
Now, steps 1 through 6 are inside of a loop as I would like to use the same workbook for all my report refreshes. My perfect solution is to iterate this loop as many time as needed to have all my reports automatically sent via email as an attachment. The first time through the loop, it works perfectly, however, the 2nd time through the loop, I noticed when the application opens up the workbook, the workbook opens up as a read-only copy even though I properly closed the workbook prior to re-opening it.
I've tried to force the open as read/write but then, the 2nd time the workbook loads, an exception is thrown. I'm on Windows 7 and I noticed that the folder properties has a read-only check box which I make sure is cleared before running the application but then when I stop/pause the application to inspect the folder properties, the check box is checked again. I'm not sure if this is why I'm having issues when I open up the Workbook a 2nd time or not.
