Unable To CTRL-DoubleClick But The DoubleClick Event Has The EventArgs?
Jun 17, 2009Within my program, I'd like to allow the user to hold the CTRL key down while double-clicking with the mouse. Specifically, within the treeview control, I'd like to allow the user to be able to CTRL-DoubleClick but the DoubleClick event has the EventArgs parameter that doesn't provide any keyboard data.I'm guessing that this is possible, but I'm just drawing a blank on how to implement it.

Jan 12, 2011I have a bunch of VB.NET programs that have a general purpose logging function to log events, errors, exceptions, etc. It looks like this:
Sub LogMe(Msg as string)
LstLog.items.add(now.tostring & " " & Msg)
End Sub
I wrote a few VB.NET DLLs that contain classes used my my VB.NET programs. In thoses DLL classes, I would like to also trap some events, errors, exceptions, etc. But I want them to be logged using my main LogMe function. Here is some pseudo-code of what I was looking for:

I assume I will need to define Delegates to save my LogMe fonction pointer

View 3 Replies[2008] Make Sure That Each Call To The Function Is Much More Random?
Jan 15, 2009I have a function called DieRoll. In the function I have the following setup.
Dim objRandom as New Random
Dim intRoll as Integer
intRoll = objRandom.Next(1,7)
Return intRoll
Everything works as expected as far as generating a random number (1 - 6) is concerned, except for one problem. If I have a series of calls to the function one after another, the numbers come up the same. Is there a way to make sure that each call to the function is much more random?
Function Syntax - Call A Function With 2 Arguments When The Function Is Only Defined For One
Apr 1, 2010I'm trying to undersatnd the syntax of calling a funciton and it seem confusing when I'm using a web service in ASP.net. Maybe this question should be in an ASP forum, but it is a VB question. This simple web service allows you to type in your name and it response with an alert box with you name.
My question is, How can you call a function with 2 arguments when the function is only defined for one. I understand that the second argument is actually a method that handling the respons, but how can you interchange function arguments for methods and how do you know that there are methods for

Function Call For Multiple Textboxes Using Visual Basic Studio 2008
Feb 17, 2010I am working to make a function that will update the back color of a text box based on multiple variables values. I can write the code to do the calculation, but I am not sure how to make the function realize which text box to update (as I will have about 30 different boxes). Below is the code that I have for each box so far, but I will have quite a few more, and would rather use a function to reduce the amount of code, and also make it cleaner as well.
If sngPreviousPrimaryPropertyTotal >= sngPrimaryPropertyTotalCost Then
txtPreviousPrimaryPropertyTotal.BackColor = ColorProgramLightGreen
Else
txtPreviousPrimaryPropertyTotal.BackColor = ColorProgramLightRed
End If
[Code] .....
Or is there a way that I can tell the function that it's updating the text box that call the function in the first place? Say if txtBox1 has updated text and calls the function, then the function 'knows' to update txtBox1, but will update txtBox2 when it's called by txtBox2.

View 2 RepliesCall A Function From Inside Another And Suspend It Until The Called Function Is Finished
Jan 25, 2010How can I call a function from inside another function and suspend the calling function until the called function is finished? I hope I can get some replies because I don't know how to ask the question and make sense:).
Anyway what I am trying to do in steps:
1. The user clicks button1 which triggers the click event.
2. From the click event I call a function
3. I then pop-up a form, that has instructions for the user to read.
4. After the user has read the form he will click the "Done" button and return to the calling function.
The problem is the the calling function continues to execute. I want to stop execution of the calling function until the users clicks the "Done" button on the instruction pop=up. I know I can use a msgbox but the instructions can be lengthly and does not look good in a msgbox.
I have tried the Call method with return in the "Done" button click but I can make that work. I also tried a goto statement but I can get that to work either. In the call statement I said call frmInstruction.show() and it got there but as I said the calling function continued to execute.

Threaded Function Call Slower Than Calling Function Directly?
Sep 14, 2010I have a function where I am performing a lot number of database operations inside a Sub. The operation when called directly like:ExecProcess()
takes about 11 seconds to run.However, if I create a Delegate, and call the sub using BeginInvoke(), the very same process takes over 40 seconds to execute.Here's the threaded code:
Protected del As ProcessDelegate
Protected Delegate Sub ProcessDelegate()
del = New ProcessDelegate(AddressOf SELocal.ExecJob)
Dim cb As New AsyncCallback(AddressOf Me.ExecJobComplete)
del.BeginInvoke(cb, del)
Anyone know what may cause a function to take longer inside a new thread, rather than calling directly?

View 2 RepliesCall A DLL Function?
Nov 28, 2010I have created a new Class Library in visual basic and called it 'TestDLL'. I have a TestDLL.vb file where I put in this code
Class TestDLL
Function ReturnHello() As String
Return "Hello"
End Function
End Class
Then I clicked on the build tab and built the solution. I then copied the DLL 'TestDLL.dll' to C:TestDLL.dll
I am trying to use that DLL in a console application. I have tried this code but I get an error: System.EntryPointNotFoundException was unhandled Message=Unable to find an entry point named 'ReturnHello' in DLL 'C:TestDLL.dll'.
Declare Function ReturnHello Lib "C:TestDLL.dll" () As String I have added TestDLL.dll to the references for the console application and got that to work, however my goal is to load and unload different .dll files without restarting the application. I have a lot more code besides this, but I'm just trying to find out what commands I could use for just calling functions from DLL files.
There was something I was reading about assemblies, but all I get that to do is list the classes in my dll file. I will already know all the names and locations of the .dll files, and also the class and functions that they contain, because I will be building all of them. how I can get a simple function return in my console application.
