I've got a richtextbox but want to check the keypresses before they come in the textbox. So I thought of using the KeyPress event from the form, checking that key and than writing it to the richtextbox with the Text property.But the KeyChar is a char while the Text property expects a string, and when I convert the KeyChar to a string(ToString) it gives a error.Does anyone know how to fix this or has anyone another idea for checking the presses before writing them?

I have a rich text box with the following text in it:
word word
I am finding the endings of the word, that is, the string "rd". The following code finds the first occurance, but then fails to find the last occurance, and the variable "indexToText " changes to -1.After the first search, the debugger shows the startLocation at character position 4, so it is not past the second occurance but still will not find it.
indexToText = FrmMain.RichTextBoxPrintCtrl1.Find(searchValue, _
startLocation, eof, RichTextBoxFinds.None)
If I change the text to:
word word word
It then finds the first two occurrences and fails to find the last occurrence.No matter how many words I add, it always fails to find the last occurrence.

I have various input textboxes on my form. And based on entries made in each of the input textboxes, I update the display textbox. However, using AppendText message of textbox. I have my input textboxes set to accept only numeric values. So for each character inputted correctly, I update the display Textbox. Problem I have is when user selects Key.Back or Key.Delete, what I would like to do is do a Delete of last character in the display textbox, but I am yet to get this right. How do I delete the last character in the string that is contained in a TextBox using AppendText()

I have a problem with Asc() function as a blow picture,I will explain each step as I do.First I convert some values to ASCII code and store in value variable, then retrieve 3rd position of variable (4th line of the picture.)
and use Asc() function to find result which it show 63. (like 5th and 6th line).But I try to manually use Chr() function, the result become 2nd and 3rd line.So for the Asc("ˆ") func. result should be 63 or 136?

I was able to Mass edit This:
Reader.Position = (&H)
NumericUpDown281.Value = Reader.ReadInt16()
Reader.Position = (&H)
NumericUpDown280.Value = Reader.ReadInt16()
Reader.Position = (&H)

And there is at least 370 NumericUpDown's. Is there any way to search/find/replace all in one instead of typing:
Find what: NumericUpDown320.Value = writer.WriteInt16()
Replace with: writer.WriteInt16(NumericUpDown320.Value)
Each individually?
The write function will only write properly this way:
writer.Position = (&H)
writer.WriteInt16(NumericUpDown66.Value)
And not this way:
writer.Position = (&H)
NumericUpDown319.Value = writer.WriteInt16()

View 2 RepliesI want to make an numerical integration method with takes in an analytic function and integrate it over a specific interval. For the numerical integration procedure I want to use some procedures in nr.com. The problem is that these are programmed in C++ and they uses functors to pass a function to the integration method. How can I do this in VB 2010?
I want to initialize the function (i.e. set a=1,b=0 for function y(x)=a*x+b) and then pass the function to the integration method. Then when the integration method call the function it only calls the function with one parameter (i.e. x since a,b is already set)
What is the best way to do this in VB2010?I want to make a general integration method where I can pass any single valued function and integration limits.
I have just started using VB, and from what I have found so far it seems like the tools you have is
- to us a delegate for the function
- to use a lambda expression for the function
- send a pointer/adressOf
- to create a function class/structure and submit this to the function
As for now I am most inclined to create a function-class. But I am not really sure how.F.ex. I make different classes for each "uniqe function" I want to integrate, but how can I pass them to the integration function when I need to specify the argument type in the integration-function-call?This seems like a basic problem which applies to many Math operations, so I think it would be very useful to clarify this.
I'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
