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 wished to have to add a code which would Wait for example to press right click while i am opening A game (MOHAA.exe)so it send to mohaa a singal of another key for example (p) and when I leave it it send the same key in brief While I am holding The right click i will do the same as i pressed (P) tell I leave the Right click It cancel the function of (P) There is 2 questions:1- How I can do the Hold Function Without Hot key Registration
[code].....i m trying to do it so tat when i press the print button, it will show up a message box saying these 2 lines then a okay button to close tat message box.
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.
how can i login when user type password and they press enter that login code can be activiate. What event can be using for this, i m using button_click event. need textbox typed value and press enter it should be login to that next form.
I just want to repeat a code block if a CheckBox it's checked...So, i'm very novice to programing in Visual Basic and i'm learning by myself doing little things like a Ping Tool.I have this code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Label1.Text = ""
I have a windows form that imports data from an xls file to sql2005. I have a browser button, a dropdown list for the sheet names in excel and a process button. Now the excel file has 3 sheets (sheet1, sheet2, sheet3) the columns and data type are not the same so I need 3 different queries to access this file,
I think about CASE, but not very sure, So if dropdown list.selectedvalue=sheet1 then run code
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.
The Timers based on System.Timers are multithreading timers, I can readBut if in my application I have two timers:1) Timer1 (based on Windows.Forms.Timers) that every 500 ms execute the program main code2) Timer2 (based on System.Timers) that every 1000 ms controls a secondary eventif in the Timer2_Elapsed event I insert the Thread.Sleep(30000)for 30 seconds ALL THE program stops, even the Timer1 controlled main code.
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.
What i am tring to do is execute certain code based on a variable held in a module someting like compiler directives, here's an example for lack of an explanation.[code]...
We have a Try/Catch block of code in our web application to trap a certain exception. What we want to do with this exception depends on the current time. If it is between 4:30PM and 3:00AM we will want to send an email, otherwise we will throw the exception.
Try 'Yada Catch ex as WebException Dim Time As DateTime = DateTime.Now
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 am trying to make a simple program to display a shipping charge based upon a selected zip code. Where can I find sample code that I can use as a guide? I can create the GUI but can't figure our the code.
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 some shared code I need to use both in a WinForm and a service. How can I test if my code is running in a service, so I can avoid problems with modal dialogs.
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:
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...
I'm looking for a library for Autocomplete support in text controls which remembers all previous entries of the user and provide auto-complete support for it.For example for "recent files" I use [URL] and it works great. Do you know something like that for this purpose?
UPDATE : This is a .NET Winforms application and I'm using normal Text Control.

I am trying to code a delete button for a browsing program based on data from a txt file. I have coded the buttons to sort(ascending and descending), append to the text file, search the text file, but I can not seem to get the delete function working. I am using VB 2010, this is what I have so far:
Code: Dim deleline As String Dim line As String Dim isFound As Boolean = False sr4 = IO.File.OpenText("Students.txt")
