I have written a C++ code to modify a string, the code is:
int Len = (nString.length());
char *szString = (char*)(nString.c_str()); // Convert to C string
for (int i = 0; i < Len; i++)
[code].....
I have this so far, but it is not working:
Dim i As Integer
Dim chrArray() As Char
chrArray = EncryptIn.ToCharArray

I have a notify icon and I use the 'Text' property instead of 'BallonTipText' because I just like it better and it fits well with my application. The only thing wrong with that is the 64 character limit. How can I determine the length of a string, remove all characters after the 61st character, then add three periods at the end of the new string? I've looked around and can't find any solution to removing all characters after the first X characters.
View 4 RepliesI have established how to use the click once system to include multiple project's exe's in a SINGLE click once deployment.
Now, with that said, it just adds the secondary project's exe(and its required files) to the install directory. Cool.
BUT, to avoid making a button that says 'Run Program 2' in Program 1's screen, does anyone know of a hack/mod to add another link to the start menu's folder?
So it'll show, Support for 'Project 1', Project 1, then add the link for Project 2?

I am writing a library in VB.NET in which I have added, among others, a class originally written in C# but converted into VB.NET. I don't know much about C# so therefore I have used online C# to VB.NET-converters. Now I am stuck with some code which I believe the online-converter was not able to "translate" properly.
When running the code I get the following error:
System.IndexOutOfRangeException was unhandled

Just wanted to know if you had some design code which was created, and that is all you have. Can you open this designer code and create the actual working main Form from this? I don't need this designer code for any specific task, just wanted to know if there is a command within VB Studio 2010 that creates the actual Form from the design code. For example; The following piece of designer code is for a simple program that finds the Circumference of a Circle.

I'm trying to convert an integer (0 to 255) into a 2-value hex string. For instance, if the integer was 255, the hex string would be "ff", if the integer was 15, the hex string would be "0f". The issue I'm having is trying to keep the leading 0. I've been able to overcome this by using an if statement to determine if the length is less than 2, in which I would concatenate a 0, but this is pretty inefficient I think. Here's my
Dim get_integer as Integer = TextBox1.Text Dim hex_value As String = Convert.ToString(get_integer, 16)
If hex_value.Length < 2 Then
hex_value = String.Concat(0, hex_value)
End If
how to improve this? I really would like to get away from using the if statement.

Just started programming with visual basic 2010 after programming a lot with vbs (Visual Basic script) it looks a lot like each other but there are a couple of differnces so here are a couple of questions.
1. What is a integer and what is a string?
2. Can i code an own sub? so it works at all times and not only when i " do something" (press a button or something like that)
for example: if progressbar1.value = 10 then msgbox " well done" now i can only add this line when i connect it to a button or something but i want to connect it to all the lines.
3. whats wrong with this line?: WebBrowser1.Navigate [URL]
Im trying to create an app that can Compile and run vb.net code while running. Like I will have a multiline textbox and a button that runs the code. The code should run as if it Were to be in a normal Sub. I've heard of system.reflection but all the examples microsoft provided have failed.
View 4 RepliesWhenever I want to modify a winform from another thread, I need to use ->Invoke(delegate, params)so that the modification occurs in the winform's own thread.
For every function that needs to modify the gui, I need another delegate function.Is there some scheme which allows me to limit the number of delegate functions needed? I have a controller class which handles the whole gui in one spot, I've thought about reusing delegates but that smells badly.I think that my question can apply to all languages where winform can run

I have a data entry form, a listview form and a couple of classes. Data is entered in the form, and it is stored in an array. This is then displayed in a listview. I can insert and delete just fine, but I cannot figure out how to modify. This is what needs to happen: With a row selected in the listview, modify is clicked in the menu strip.
Whatever information is in the selected row, it needs to be transferred to the data entry form where changes to it may be made. I have attached what I have so far, and a sample data file is provided in the root directory. I think I need to temporarily store the selected item, put it into the data entry form, delete it, and when submit is clicked have it re-inserted.

My VB.NET code is supposed to execute third party Javascript code in an attempt to fill in and submit a form. This process consists of five steps, and I have been able to submit the form when all the steps are kept separate (i.e. behind 5 separate consecutive button clicks). Now, what I'd like to have is one button to handle all the five steps.
The problem is that the form originally only appears after calling "webbrowser.Navigate" command, which apparently modifies the page's HTML code. I seem to be unable to detect when Javascript has finished loading the new HTML in order to fill and submit the form. I have tried a timer control to wait for a certain HTML element ID to appear, but in vain. [URL]
