i want to make a program that will 'clean' up a computer, so far i can make it delete temp files, clear history, empty the recycle bin, even startup windows disk defrag... basic stuff like that Now i want it to go into windows registry and add some preset values, for example: HKEY_CURRENT_USER // Control Panel // Desktop // MenuShowDelay is by default 400, but i want to set it to 200 or something...i would also need the program to figure out which OS the computer is running (xp/vista/7) and only use the appropriate key and value,
I want my application to startup thorugh registry if the specified checkbox1 is checked and to delete it from registry if the checkbox1 is not checked.With the following code im able to create registry but, im unable to delete it.I want it to work like it works for softwares for e.g Utorrent.
Code:
Private Sub CheckBox1_CheckStateChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckStateChanged If CheckBox1.Checked Then[code]....
I wrote an application to manage several installers and I wanted to throw in some registry settings as well. Unfortunately the following code is not writing to the registry, nor is it returning any exceptions.I'm running Visual Basic 2010 Express as administrator using Windows 7 64 bit, I can manually add the values, and I can add them from a .reg file manually but not even by calling the .reg file as a new process (it asks for permission, says it succeeded, but nothing changed).The key already exists, all I need to do is add two values.
I've been playing with a DGV. Let's say for my question here, I want a grid that is 10x10. I would like the font in each cell to be Arial 10 regular. Only one character will be in each cell (I'll use "M"). I would LIKE the cells to be 17 pixels by 17 pixels. But, if I manually force the column width to be 17, I get about half of my M and three dots "M...". I'm thinking this is a padding thing but as far as I can tell, everything is set to 0. See code and then more comments below:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load With DataGridView1
[Code]....
Question 1: How can I reclaim some of what seems to be lost space around the cell contents so I don't have to make them bigger than they need to be? I'd like them to be 17x17 with the single character centered within.
Question 2: Do I have to manually set the height and width of each row and column? I'm thinking the RowTemplate setting but can't seem to get it to work.
FYI: This is a new project with a DGV dragged onto the form. All changes have been made programatically.
Is there any way I can open a registry file that is not from the local machine? I have the software and system files from another PC and need to create a small code to read and get values from the files. The other PC is down and I just have the registry files so I ruled out the OpenRemoteSubKey method. However, the My.Computer.Registry.GetValue only works on the local machine.
i have problem with searching key value in registry I have that
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim itm As ListViewItem Dim root As RegistryKey Dim searchkey As String = TextBox1.Text
[code].....
But on line: For Each valueName As String In root.GetValueNames, it says: Object reference not set to an instance of an object.
My first time and first post here.I am trying to change specific registry key values (to enable fast user shutdown), but I get an error message when I try this. I will hopefully be implementing a number of the TweakUI functions, but in my own representation.
[Code]...
and I get the following error message:
"The specified RegistryKeyPermissionCheck value is invalid. Parameter name: mode" (I've changed the Security.AccessControl options but none of them are suitable)
I've only been using VB 2008 for about 4 months now, and had no coding expereince prior to this
I have tried to solve this myself and I know I am probably doing something really silly here what I have is two different registry values that control what is displayed in the combobox on my form RegistryKey1 has the following values:0,1 or it does not existRegistryKey2 has the following values2,3, or 4 the combobox has the following values 0,1,2,3 However here is the problem if the RegistryKey2 is 2 then it further has to be checked if RegistryKey1 is either 0,1 or does not exist
if it is 1 then the selectedindex = 0 if it is 0 or does not exist then the selectedindex = 1 if RegistryKey2 is 3 then the selectedindex = 2
This time i'm tring to work with registry values and so i'm using the following code Private Function RegKeyExists(ByVal hKey As Long, ByVal sKeyPath As String) As Boolean
I would like to get applications that run on start up as show them in a list box (Name Value & Data Value). The registry key where the information is stored is HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionRun. I have wrote code before the gets the subkey values and list them but I'm having trouble remembering how.
I am a newbie so please forgive me if my terminology is incorrect.I am trying to Update a Registry sub key value. I have done this a few times before with success. But this time is kinda different. I noticed a few things,like the sub key value is in HEX when I export the key (The value that I want to input is from a sub key that I exported) I can only get the registry to accept the command if I do not specify the registry value kind, but that doesn't do me any good if its not the correct value kind.
What im trying to achieve is editing the value of this key; But I've tried everything i can think of.. I've tried just entering the name and type etc. but nothing..I've decalred:
Imports Microsoft.Win32 and the code im attempting to use: Dim regKey As RegistryKey
[code]....
What i want it to do is create a key from the Drive Selection box i.e. 'H' then create two sub keys called 'DefaultIcon' and 'DefaultLabel' and assign values to their (Default) key but its not working.
I have little MD5 Check Sum app, and I want if i click on some file in the entire Windows OS, with right button, in the context menu there to be a button "Check MD5 Sum". Like when you install WinRar, the app assign values there for archive, and extracting.
I have a program which will search the entire registry for a keyword and display all the matching keys/values in a listview. The user can then select the desired keys/values and delete them. Since this a program that deals with registry, I want to give the users a way to backup the registry before they do the delete operation. I would like to know what is the best approach for this.
3 questions here: 1- Should I backup the entire registry ? 2- Should I backup only the keys/values that the user has selected in the listview ? 3 - Can I have the sample code or appropriate URL's which describes this.
Okay, so I have to convert letters to numbers, each letter in the alphabet is assigned a value that I've assigned. But I need to run through a textbox letter by letter, and convert that letter to the numbers that I have, and append. So if I had a textbox with "JANE", it would output 942383312318265498643 assuming that the following letter values were true
Previously I asked about sending emails. And now, I have a related question.How to use a preset message in the email ?
Dim strMessage As String = "Hi [USERNAME]..! You have not paid your due amount of Rs. [DUEAMOUNT]. The last date for payment is [LASTDATE]. I want it to be in such a way that, when a button is clicked, all users with pending amount will be selected (from db) and the above preset message is formatted with each user's USERNAME, DUEAMOUNT & LASTDATE, and finally added it to another table in my db.
Presently my idea is to use a SELECT query for getting all the pending users and then loop through each user (record) and add the preset message to a separate table (this table contains all drafted messages which will be then sent to the recipients), by replacing the USERNAME, DUEAMOUNT & LASTDATE using the Replace function.
I have a ton of MP3's that have an extremely high bitrate (like 200+) and I am trying to create a program that will 1. Read my MP3 Folder structure (DONE), 2. Create a list of MP3's that need to be rebit (DONE with UltraID3Lib), and 3. Resample the file to be a preset bitrate like 128... I don't want to have to reinvent the wheel on this one.
I have a connection to an access database, I have used the data sources tool provided because in this particular instance I don't want to do much with it other than display the records (which I can do) and edit them (which I'm haveing some trouble with).I have created a system whereby the database is connected to using the preset tools available like; BindingSource, TableAdapter, BindingNavigator etc.
I also have a button for edit. This doesn't work and I was wondering if anyone could help me with this? I can't really provide any code for this, because I didn't code the connection by hand and the code I have been attempting to use for editting the records in the database doesn't even sort of work.
How can I crop an Image to preset dimensions and size using code.I can do this with MS Office Picture Manager, but I want my users to do this from within the app. using the preset dimentiomns and sizes.[URL]
I'm trying to create classes, functions, etc that present a preset list of options to users (in the same way that messagebox control will show the available button options). A simple example is readFile(ByVal strPath as string, ByVal strFileType as string) where the user will see a list of acceptable file types when they put the comma after strPath.
I am rather new to VB and every now and then I get an idea of a small project I would like to work on to increase my skills. What I am trying to do is: 1. Input the sound from the microphone 2. Detect what pitch the sound is 3. Compare it to the pitch displayed
For example, lets say I was to have the button "Start". When start is clicked, a pre determined (Or possibly random) note is displayed through a Label for 5 seconds (Lets use C as an example). During this time, the user can attempt to match the note C. When the user sings through the microphone VB picks it up, detects what note the user is singing at, and then scores him over the 5 seconds based on the difference between his note and C. It would also be nice if I could display the volume of the microphone, but this is not too important.
how I can make my Application to automatically create preset folders with files when installing the application? The files should be under user/documents/MyApplication/Newpresetfolder
I am looking for assistance writing code, (VB 05), that would cause an object, (like a circle on screen), to get larger and smaller over preset periods of time, (about ten second increments).
a program and i need to have a button put a file into a folder, i know how the button works i already have it doing some other stuff. i just don't know the code to copy and past it to a folder.
