VS 2008 Changing The Path (environment Variable) Under VISTA With VB?
Mar 27, 2009
i need to change the "PATH" environment variable in a VB program (Visual Studio 2008). Here is the code i use to add the "C:TEST" folder at the end of the existing one.
test
Dim PathVal As String
PathVal = Environment.GetEnvironmentVariable("Path", EnvironmentVariableTarget.User)
Overreaching amateur developer that is outsourcing some of my work and doing part of it as well. I've been working on a dictionary/ thesaurus / spell check & suggestion application that I am trying to get to work on all applications within the windows environment.
I've used hooking to get key stokes and show output as the person is typing for definitions and spelling suggestions. This isn't accomplishing everything I want. Works fine for spell checking and suggestions but to click on a word that already exists or for touch screen interfaces to touch a word it doesn't work.
I was reading the Raw Input API on MSDN and thought that would work but my developer that I've hired is advising me that the RAW input's scope is only on the window that has focus and so cannot do low level hooking. I'm considering giving the effort but wanted a 2nd third fourth perspective prior to making the effort.[URL]
I have a form, and essentially, I want to open the .txt file when it is dropped on my program, in textbox2 in form1. I read you use Environment. GetCommandLineArgs(), but how exactly would you do it?
i compile my form with the below code when i run it on vista work fine without any problem but when i try to run in on XP cant run... that happened with any XP machine.[code]when i run my exe to other Vista machines work fine... but on xp NO.
with vb.net 2008 expressmy intention is to change the value of a variable to dbnull.value if the variable = ""so that i can insert null values in to the data base
Module sonsilaxa Public Function deFcheck(ByVal i As String) If Not i = "" Then
The following procedures sorts a listview column based on what the tag is, 'Numeric', 'String' or 'Date'. When you click on the column header the sort procedure kicks in. On the first click it will sort ascending and on the second click it will sort descending.
My problem is that when I click a second time it won't sort descending but re-sorts ascending again.It appears when the sortorder is passed to the ListViewColumnSorter.vb classes it changes back to ascending even though it's called as descending. I've bolded the offending variables using a Numeric search.Now here's the really iritaing thing, I have exactly the same code in another application and it works perfectly?
Private Sub lvwResults_ColumnClick(ByVal sender As Object, ByVal e As System.Windows.Forms.ColumnClickEventArgs) Handles lvwResults.ColumnClick SortMyListView(Me.lvwResults, e.Column, , True)
I am wondering if I can use VB.NET(I am using visual studio 2010 express) to get and set a environment variable.
I want to add path of my application on system environment. I want to preserve what is already there and then I wan to add my string. This can be done by getting value of PATH and then append my string then re writing it.
I have 2 questions here:
How to get/set system variable in vb.net 2010? Will it be on the fly, I mean will it be immediatly avaialble in dos prompt or there will be delay?
As just for experiment i opened a command prompt then updated the PATH variable manually and it was not updated. I am wondering it I do it through programe it will be same.
I think my title covers the high level, but for indepth; i need to be able to connect to a machine through and ip and set a enviroment variable, i have over 60 machines in different states all on one network that i need to do this for as well as someother things for the machine. currently this is being done through a PCEXEC command in a batch file they want more control on how this operates. I just really have no idea where to even start looking for the enviroment variable change(setting one on a machine that the app is running is simple we all know that. but on a external machine im lost) on a remote machine.
I have researched the Internet and found more than a few potential solutions, but I keep getting errors on a Windows 7 machine. Here's the scoop. I have an application written in VB.NET that launches a console application. The console application will run independently of my VB.NET app, so the user can close and restart the VB.NET app and potentially start a second session of the console app from the same installation.
I would like to ask about publish project in Vb.I am using OneTouch in Vb After I have publish the project, all information (database, images, other files ) will be put in this C:Documents and Settings ewuserLocal SettingsApps2.0
I am trying to change the DWORD value in a specific registry path. It starts with the user who is entering the value in decimal into a text box. Then with the click of a button, the application takes that value and change the existing value of the DWORD to the new one typed into the text box. I think I have manage to get it to work with "strings" but I seem to get stuck when it comes to the DWORD key. I have a feeling it have something to do with the hexadecimal value which is set by default. Do I need to create a converter?
I created a project in vb.net which is connected with database. The problem appeared when i changed the path which connect with the database, i made it relative. So some of the forms which contain the connection are working properly but in one form i got this error: [Code]
but, when I run it, it produces an error: Compile Error: Variable not defined and it points to the second "Environment" string, the one inside the parenthesis. Is there a reference that I should be enabling?
[ProgramFilesFolder][Manufacturer][ProductName][Version] is the Default. i Want to change the programfilesfolder to documents folder.
I already try this:
[DocumentsFolder][Manufacturer][ProductName] but it doesnt work. error in installing the product. ERRROR: "Could not access network location Polongo companyMC"
Iam changing the installation directory because when the application is installed in program files, my database can't add and edit record. having an error something like "operation must need an updateable query" because of that error i tried to install the appl in documents and there n error i'd encountered like when I install it to the program files folder.
I have VB6 Dll which I am referencing in vb.net ,I am calling the following function in it. It working fine in developemnt environment but not in deployement environment.
Error Method not found: 'Boolean MyUtils._MyUtils.LoadMyObjectRecords(ADODB.Stream ByRef, System.Array ByRef)'.
am running VB express (2008 edition). I have a class that holds 2 arrays (1 array represents the digits of the integer side of a number the other holds the decimal digits) I have overloaded all the operators to work with these numbers as if they were one. Each operator has the following format:
[Code].....
whats happening is that the sign of the b variable (and only the b variable) randomly changes. Almost allways at the statement bb=b (bb is in place so when I reach that point I know what the variable had before the calculation). I can watch it change as I step through the code (stepping over the operators) I can watch it change almost allways at the bb=b, but sometimes in other odd places (such as the d=a*yparam statement). I can change the values back to their original and step through the code(stepping into the operator this time) and it will not do it. It NEVER does it when stepping into the operator, only when I dont, and only sometimes. I have spent the last two days working on debugging this one problem, with every other variable in the function it works like it should and I am not sure what to look at next. I know it does you no good without seeing the code but didnt think pasting 8,000 lines of code would go over too well so I would be willing to send the source to anyone
I am trying to allow my VB.NET EXE to have a variable defined by the run command. The problem is I have no idea what the terminology would be for this type of run.
For example - the shortcut is set to do "myexe.exe debug" This would set a variable to "debug" which on execution my app knows to enable a debug mode.I've done it in batch scripts before - it just enables the "%1" variable or "%2" based on the location (e.g. test.bat hello world - hello would be %1 and world would be %2).Hopefully I explained it well. I tried searching for "variable in execution path" and "variable on execution" with other mixes, but none of those searches return what I am looking for.
I can't seem to get this to work. I am just a novice plugger and do some of these forms for my work occasionally. I am assigning a textbox result to a variable. I then want to use that variable in a path string i.e. ("c:some stuffvarname") but the variable looses focus once placed inside the quotes.
I am using Vb.net. I have a counter variable Dim rc as Integer This is a class level variable. loading the page for the 1st time, its value should be 0.But later I manipulate its value in various methods.My page reloads after most methods & the value of rc is re-initialized to 0. how can I avoid this. I need the page to reload but the counter should keep incrementing.
I am concatenating a variable onto a path(string), i'm using a message box to display this for testing purposes, I can see that the variable is starting on a new line, which in turn when i try to open the file it doesn't recognize that the file exist...
Dim Path As String = "C:UsersstefanDesktopUni WorkYear 4ProjectsProject SelectionProjectProjectinDebug" Shapetext = clickedShapes.Item(nextShape).Text.ToString.Substring(0, clickedShapes.Item(nextShape).Text.IndexOf(" ")) MsgBox(Path + Shapetext + ".txt")
How can I create a DLL declare statement with an environmental variable in it so as to make sure that I'm loading the system DLL from the right place, the system32 folder? For instance...
Declare Function GetExtendedTcpTable Lib "iphlpapi.dll" Alias "GetExtendedTcpTable" (ByVal tcpTable As IntPtr, ByRef tcpTableLength As Integer, ByVal sort As Boolean, ByVal ipVersion As Integer, ByVal tcpTableType As TcpTableType, ByVal reserved As Integer) As UInteger
The reason I'm asking is that there has been talk about people injecting invalid/malicious DLLs into folders along with applications and whatnot and I see this as an issue if you don't specify the SYSTEM directory. Yeah, I could specify it to load from c:windowssystem32 but what happens if a person doesn't have their Windows installed in c:windows? Hence the reason to use an environmental variable to find system32.
I am relativel new to using the .Net framework. I am trying to learn how to set the path of a file to a variable, and having no luck. I keep getting a message that indicates that the path can't be set. The error seems to be a runtime error. Here is the code
