What kind of apples do you want to know more about? Red apples? Green apples? Yellow apples? Apple the company? What does this have to do with any kind of Visual Basic question?
Why is common sense not common?
Never argue with an idiot. They will drag you down to their level where they are an expert.

And what about trace? Are you looking for something like this[^]?

They used to be seeds.
One of these days I'm going to think of a really clever signature.

That still doesn't help much, but I guess you are looking for something along these lines[^].

One loop is an indexer and the other is an enumator.
Indexers can modify the collection while you're iterating over it while enumators cannot.
Indexers are a little faster than enumerators, but also require you to know more about the size and types the array holds.

Thank You Dave. It clear my mind.
|
|
|
|
|
Just to add to Dave's comment - The for-loop is faster than the foreach-loop if the array must only be accessed once per iteration. (More Details with Benchmark Test[^]).

I'm having a problem I can't seem to find the source of in a program I'm developing. The following function parses an XML file to find the names of registry keys and associated values that are linked to the selection of a drop-down box in the UI. The function retrieves keys with no problem. when asking for the values, it always returns 0, and I can't seem to figure out why. Thanks for taking a look and any suggestions/solutions you may come up with.
I've included the source of the function below and a sample of the XML -
Public Function GetCfgOption(ByVal strSetting As String, ByVal intSelectedIndex As Integer, ByVal strDataType As String, Optional ByVal intOptIndex As Integer = 0) As String
Dim xmlSettings As New Xml.XmlDocument
xmlSettings.Load("SrcBench.xml")
Dim nodeSetting As Xml.XmlNode
nodeSetting = xmlSettings.SelectSingleNode("/CONTENT/Settings/" & strSetting & "[Index='" & intSelectedIndex & "']")
Dim nodeOption As Xml.XmlNode
nodeOption = nodeSetting.SelectSingleNode("/CONTENT/Settings/" & strSetting & "/Setting[@Index='" & intOptIndex & "']")
Select Case strDataType
Case "Key"
Return nodeOption.ChildNodes.Item(0).InnerText
Case "Value"
Return nodeOption.ChildNodes.Item(1).InnerText
End Select
Return Nothing
End Function
This function would be called like so:
GetCfgOption("FilterMode", intFilterModeIndex, "Key"<, 0>)
GetCfgOption("FilterMode", intFilterModeIndex, "Value"<, 0>)
GetCfgOption("FilterMode", intFilterModeIndex, "Key", 1)
GetCfgOption("FilterMode", intFilterModeIndex, "Value", 1)
This could be tested using a Console.WriteLine() statement. Calling the function with "Value" always returns "0".
The following is a section of the XML file being accessed:
="1.0"="UTF-8"
<CONTENT>
<Settings>
<FilterMode>
<Index>0</Index>
<Option>Bilinear</Option>
<Setting Index="0">
<Key>mat_forceaniso</Key>
<Value>0</Value>
</Setting>
<Setting Index="1">
<Key>mat_trilinear</Key>
<Value>0</Value>
</Setting>
</FilterMode>
<FilterMode>
<Index>1</Index>
<Option>Trilinear</Option>
<Setting Index="0">
<Key>mat_forceaniso</Key>
<Value>1</Value>
</Setting>
<Setting Index="1">
<Key>mat_trilinear</Key>
<Value>1</Value>
</Setting>
</FilterMode>
<FilterMode>
<Index>2</Index>
<Option>2x Anisotropic</Option>
<Setting Index="0">
<Key>mat_forceaniso</Key>
<Value>2</Value>
</Setting>
<Setting Index="1">
<Key>mat_trilinear</Key>
<Value>0</Value>
</Setting>
</FilterMode>
<FilterMode>
<Index>3</Index>

</Setting>
<Setting Index="1">
<Key>mat_trilinear</Key>
<Value>0</Value>
</Setting>
</FilterMode>
<FilterMode>
<Index>4</Index>
<Option>8x Anisotropic</Option>
<Setting Index="0">
<Key>mat_forceaniso</Key>
<Value>8</Value>
</Setting>
<Setting Index="1">
<Key>mat_trilinear</Key>
<Value>0</Value>
</Setting>
</FilterMode>
<FilterMode>
<Index>5</Index>
<Option>16x Anisotropic</Option>
<Setting Index="0">
<Key>mat_forceaniso</Key>
<Value>16</Value>
</Setting>
<Setting Index="1">
<Key>mat_trilinear</Key>
<Value>0</Value>
</Setting>
</FilterMode>
</Settings>

How to code the month control or datetimepicker to have month. I don't want to have 2 datetimepicker. Is there a way for user to only choose month then display that months data from 1st to 31st for example?
I have no idea how to do because each month has different days.
|

Get the month and year from the user then use the DateTime.DaysInMonth method to get the number of days in that month.
When you have those two things, you can make two DateTime objects using the month and year supplied by the user. Use the 1st of the month to start the date range and the number of days returned by DaysInMonth to create the second date value.
There's your date range. You just supply those two dates to a couple of parameters in your SQL query (PLEASE USE PARAMETERIZED QUERIES AND NOT STRING CONCATINATION!!) to retrieve the data.
If you don't know what a parameterized query is, Google for "VB.NET SQL Parameterized Query".
