Press A Key Based On Code Value
Jan 23, 2010
Example: When you press "a" you want your program to automatically press again the same char you pressed. You know the e.KeyCode which is 65 for "a" and the command which is SendKeys.[code..]
Simple enough and it works for every character. But if you try it lets say with the Caps Lock button then the value of key is "CAPITAL"which means that the command will execute as follows:
[code..]
Which will obviously send the text "CAPITAL" not the key "Caps Lock".The same thing happens with % (Alt) and Is there another way to press a key without using the SendKeys function?
Don't stay on this:
When you press "a" you want your program to automatically press again the same char you pressed.
Cause that is not what i want to do.

I've been using SendKeys in a program I am making but its really glitchy and does not work properly.
Is there an alternative way to simulate a key press within code?

I come to programming from a school of functionality rather than theory- writing programs to meet a goal or solve a problem.I haven't had any education in computer science so many aspects of the Visual Studio world are alien to me.Just for fun I wrote a very small program to help with a computer game.It's called the All Lucky Sevens calculator for Final Fantasy 7.If you haven't played the game it won't make much sense to you so I'll eschew the logic of why I wrote it, focusing on what it does.
Basically it performs a series of percentage calculations on a number input by the user, trying to convert the original number into one that ends in 77. So 6104 reduced by 7% is 5677 The question is, how difficult is it to convert VB.NET code to work as a web-based app. I thought .NET was designed to make it easier to do this? Is it relatively simple to convert VB.NET code into something that can be run from a website? If not, the solution is to rewrite it in a different language like Java or Flash.The actual programming of it would not be difficult, but I do not speak those languages and it would require rewriting all the nested loops and ifs.Forcing VB to round down a decimal to an integer was difficult enough, I daren't think how hard it is in a language I've never used before.

I think about CASE, but not very sure,
So if dropdown list.selectedvalue=sheet1 then

Is there any way to build a web based chat room application by using VB.NET as behind code and put it with ASP.NET on the web so users can login the account and start to chat without keep refreshing the browser or frame and have a real time transaction, I know that I have to use .NET.Socket namespaces, but don't know exactly how. I have seen many examples of windows based applications, but I need to know how to put it on the web.

I have a user control which is essentially a main menu I can place it into my MasterPage hard-coded, but I don't want that, I want to be able to dynamically place it with the code behind of the MasterPage.
<controls:mainMenu ID='MainMenu1' runat='server' />
So what I am looking to do is something like
if **condition is true ** _ response.write('<controls:mainMenu ID='MainMenu1' runat='server' />')
Of course, I know that won't work, but how would I place the control based on a condition in code behind on the master page?

I am new to VB and I have two detail listviews with one full of items that can be droppedinto the other. I have three groups in Listview1 and I would like different forms to open up based on the group each dropped item belongs to. I was able to open Form2 on drop by adding Form2.Show() at the end of the ListView_DragDrop handler sub, but this opens forevery item and I want different forms to open depending on the ListViewGroup the item belongs to.I set the items and groups in the property windows and not in code; I do not know if this makes a difference. So here is the code I have on Form 1 where the listviews are:Public Class Form1
Private Sub ListView_ItemDrag(ByVal sender As Object, ByVal e As _
System.Windows.Forms.ItemDragEventArgs) Handles ListView1.ItemDrag, _
ListView2.ItemDrag

I need some help in the creation of a program to generate a security code based on the current date. I need to create something that first multiplies the MMDDYY (ie X=MM * DD * YY) then also adds the MMDDYY then finds the remainder and then multiplies but a specified number. I would like to create a small program that sits in the system tray with this code displayed. The code will always need to be 6 characters, so I might need to pad it with zeros. It has been years since I took basic VB, and I am really rusty.

I have an old system developed in Visual Basic. How can I determine what Visual Studio version to use based on the source code files? I've tried to upgrade the application using VS2005, VS2008 and VS2010. With VS2005 when I attempt to upgrade the source, it says the system was developed in a newer version. I currently have VS2005 version 8.0.50727.42 installed.

I've one VB.net 1.1 based windows app. I recently added the app.config files. In code it works fine. But, when I compile the application, VS 2003 doesn't generate the appname.exe.config.(I read on google) I manually copied the app.config file to the Release folder. But the code is giving error that the file doesn't exists.

I have a grid containing rows flagged with different priorities. I want to color the high priority rows red, low ones blue, etc. I'd like to set the shade based on a mathmatically calculated gradient rather than arbitrarily assigning colors to specific priorities. How can I extract a single color from a single point along gradient?

I have a set of classes that mimics enums (see my other questions for specific details/examples). For 90% of my project, I can compile everything in at design time. But the remaining 10% is going to need to be editable w/o re-compiling the project in VS 2010. This remaining 10% will be based on a templated version of my Enums class, but will generate code at runtime, based upon data values sourced in from external configuration files.what my Enums class looks like. The templated fields, per that question, will be the MaxEnums Int32, Names String() array, and Values array, plus each shared implementation of the Enums sub-class (which themselves, represent the Enums that I use elsewhere in my code).I'd like to parse values from a simple text file (INI-style) of key/value pairs:
[Section1]
Enum1=enum_one
Enum2=enum_two
Enum3=enum_three
So that the following code would be generated (and compiled) at runtime (comments/supporting code stripped to reduce question size):
Friend Shared ReadOnly MaxEnums As Int32 = 3
Private Shared ReadOnly _Names As String() = New String() _
{"enum_one", "enum_two", "enum_three"}

I'm certain this would need to be generated in MSIL code, and I know from reading that the two components to look at are CodeDom and Reflection.Emit, but I was wondering if anyone had working examples (or pointers to working examples) versus really long articles. I'm a hands-on learner, so I have to have example code to play with.

I already know how to call insert, update, delete & select procedures in DataSet.xsd window. And I also know how to call queries by table adapters. But I just found out that its not possible to call all functions by queries (such as insert). It works when I test the query but when I try to add it, it says "Failed to get schema for this query". So I built a few stored procedures which do many functions (such as transaction, insert, update etc...). But I am unable to use these stored procedures in VB form. I found some tutorials mentioning that it can be done by defining connections and some other stuffs with which I don't want this to be. I want to call these procedures by writing code in VB code editor window with DataSets, TableAdapters, BindingSource etc...
