View 13 RepliesI am looking for assistance writing code, (VB 05), that would cause an object, (like a circle on screen), to get larger and smaller over preset periods of time, (about ten second increments).
View 6 RepliesI'm a little foggy on System.Type versus an actual class type (like Object or XmlDocument) in .NET... will this code correctly determine if the type of a particular object is equal to a class I specify?
// Given "myObject" (unknown type), and some class type (let's say "MyClass")...
If myObject.GetType.Equals(MyClass)
If TypeOf(myObject) Is MyClass[code].....
Which one is correct? Bonus points if you can provide some information on what a class identifier is versus what a System.Type is. :)
Note: The language doesn't matter here, VB.NET or C# is fine, the code above is pseudocode.
I have a problem with a sql query. Through the query I am trying to search database for any occurrences of string (can be anything) in a column using the SQL LIKE command. The problem is that it works fine for most of the strings say john, jim, ji"m , but does not work when i include the following characters which are ( ' , { , } , and a single quotation mark). MYSQL query takes care of these special cases by putting them in [] block whenever user enters them .But i am getting the following error when i go to query the database using the GetSelectCommand() in VB.NET
Exception Details: System.ApplicationException: Number of values provided must be equal to the number of placeholders in query.I have checked the query over and over again .. but its fine .My database server is Sql Server 2008.So my application throws the exception in this command:
Using reader As MustDisposeDataReader = _
pmSystem.DatabaseManager.GetSelectCommand(selectStatementBuilder.ToString(), New Object() {})
Where MustDisposeDataReader is an instance of a class in an internally developed library, which inherits from System.Object. pmSystem is an instance of the class PlanManagerSystem which implements the commandlayer. GetSelectCommand() takes the select command
I understand the concept of bytes and declaring variables to save on processing space. I understand that the max value that can be stored in a byte is 255. I cannot seem to wrap my head around my current issue. I don't have much experience working with byte manipulation.

View 2 RepliesI have been searching the internet trying to understand in its simplist form why this behavior happens.
Dim mysingle As Single = 456.11 Dim mybool As Boolean = mysingle = 456.11
In the lines above mybool becomes false. I found this behavior when putting the single into a double I found extra digits showing. The .net documentations states a single is an approimate value I gatehr a single is a 32bit floating point number? But why are extra digits appearing when I have explicitly said what the number is.. surely the memory should store that numbers either side of my number are 0 to fill up the memory location?

I've written a piece of code that takes 3 fields from a database and writes out the 3 added together, but with the middle field cropped down, so that the total number of characters is always 28, what I thought was the width of my listbox. I realised when I debugged though, that the listbox was docked and grew or shrank depending on the size of the screen.
Is there a way to determine how many fixed width characters will fit in a control, at run time?

View 1 RepliesI'm making an app with several forms and wanted to add a label to each form that, when double clicked, would resize the form to 10 x 10 pixels.
ControlBox, MaximizeBox, MinimizeBox, properties are set to false so there is no title bar. No text or icon. MinimumSize is set to 0,0.
I made a new project that consists of one form with one label to make sure there was nothing in my code causing the problem but still every time I double click the label the form is resized to 27 pixels high by 112 wide.
The exe can call functions and forms in the dll's that are part of the solution BUT is there anyway
for the dll's to access forms, dataset's etc in the main exe project?
It doesnt appear that it works that way.
I forgot to add this is a VS2005 application.
How about a Nibble etc.

View 1 RepliesI am trying to take a png file (around 2000 x 2400) and split it into 8 smaller images of 500 x 1250 each (2 rows of 4), each of which is saved as a png file. I then which to display these smaller png files in a picture box so that they look as if they were one image.
My problem is that when I display the png files in the picture box, lines that look like grid lines show up in the picture box at the points where the png files sit next to each other.
When I view the smaller png files in Paint it appears as if the left column (x=0)and top row (y=0) of each file is set to clear (or transparent). What shows up in the picture box is the background colour of the picture box.
This clear/transparent row and column are not added on to size of the smaller png files. They are still 500 x 1250.Not every file is affected. If the smaller files are created from the original bitmap in the following order[code]...
I'm trying to rotate a mirror, which I represented by a line across a specific point. I translated the point of rotation to the center, rotated by an angle indicated in a text box and then translated it back to its original position.
Here is my code :

Dim theta As Single
Private Cntr_X_blu_Mirror As Single = 5

I hope the code is good. The problem I encountered is that the line becomes smaller and smaller as I rotate it. and that's bad! Sometimes it even grows longer [I think when I rotate it in the oposite direction!]
Also, when I rotate it at 90 degrees, the rotation does not resembles a 90 degree rotation. It seems to be inclined at 45 degrees instead!
