Kind Of Make This Loop Work Faster?

Dec 10, 2009

Basically what i need is for something to look at the items in a list box then compare it to the contents that is in the database. The issue is that the listbox can have more than one of the same item. For instance, LstBox_Order.items(0) could be the same at any position in the listbox. This code works, but it is slow if there is like 10 or more items added.

How To Make It Work Without The While Loop

Jan 1, 2011

VB.NET While 1 = 1
Dim localRecv As New StreamReader(localClient.GetStream)
Dim aString As String = localRecv.ReadLine
localRecv.Peek()
MsgBox(aString)
End While

Basically "aString" will keep updating if new data arrives to the server. This way does work, and keeps MsgBoxing every time I get new data, but I don't wanna use While, I need something else, because It won't run any other code, just keeps looping that. :/

Make A 'like' Statement Or Use Some Kind Of Wildcard To Make The Statement Not Case Sensitive?

Jul 11, 2010

I'm building a listview search feature in my app. (See the code below). It works really well, except if you search "T" then the code removes all items, if you search "t" then it removes every item except for those starting with "t". Is there any way to make a 'like' statement, or use some kind of wildcard to make the statement not case sensitive?

VS 2008 Make A Function That Does What This One Does But Works Faster?

Oct 27, 2009

I have a function that I use quite a bit that I wrote more than 2 years ago. It works fine but recently I saw how it can use up a good deal of time under certain condition. Here's some code that uses the function SelectValue The function works so that if you had N which you plug into the function rising continuously while SelectLimit was set to 255 then SelectValue would match N until N reached 256. SelectValue would start to descend to 0 until it reached 0 and then it would again ascend to 255 and the process would repeat. So SelectValue(255, 255) would return 255 and SelectValue(256, 255) would return 254. SelectValue(257, 255) would return 253.

Option Strict On
Public Class Form1
Dim sw As Stopwatch

[code]....

The function works exactly as I want it to but if one of you knows a way to write this so that it will process faster then you can let me know. I get a result for processing time of 6.11 seconds on my computer for the above code.

PerformClick() Doesn't Work - How To Make It Work

Feb 2, 2011

I have an application that requires data be entered, and after entering, a button is clicked to process that data. Clicking the button works just as it should--the data is processed properly. In constructing a test module, I provide a set of data values, followed by:

btnWhatever.PerformClick()

Nothing happens. I have used this syntax for years, and it has always worked flawlessly. I have triple checked everything else and isolated the problem to the failure of the PerformClick(). The PerformClick() is in a test subroutine that does nothing but fill textboxes and labels with default data, then calls the PerformClick() on the button to begin processing. Again, the button works fine, the data is entered as it should be, but the PerformClick() does not fire the click event.

Using For Each Loop To Work With Controls

Jan 2, 2012

I can use the below code snippet to clear the text from each textbox on a form.
For Each ctl As Control In Me.Controls
If TypeOf ctl Is TextBox Then
ctl.Text = ""
End If
Next

But if I want to use it to ensure that all radiobuttons in a group of radio buttons are unchecked then it doesn't work i.e.
For Each ctl As Control In Me.Controls
If TypeOf ctl Is RadioButton Then
ctl.checked = false
End If
Next
I'm assuming it is because the checked property is not common to all controls.

Can't Get Loop To Work - ASP.NET | Dream.In.Code

Feb 21, 2010

I created this ASP.NET Web application and I can't get the amoritization table(MonthlyPaymentBox) to loop correctly. I think the problem is somehow in my code I am setting the TotalLoan = 0, but I just can't locate where that is happening. I assume this because instead of of starting the current balance at the users input, it starts at 0.
