VS 2008 - Writing To Vista Registry (Unauthorized Access)

Sep 19, 2009

I'm running Windows Vista with admin privilege and UAC is disabled but still unable to write to windows registry!
My.Computer.Registry.SetValue _
("HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRun", _
"Test", "C:Test.exe", Microsoft.Win32.RegistryValueKind.String)

I'm getting error "Unauthorized Access Exception was unhandled."
"Access to the registry key 'HKEY_LOCAL_MACHINE....' is denied."

I've googled the net and found that registry permission elevation is required for admin tasks, Is there away to take registry key ownership through VB.Net code??

File I/O And Registry :: Writing To The Registry?

Oct 27, 2010

I just bet the answer to this question already exists, however I saw no search mechanism under the forum. Anyhow, I would like to change registry data, and this code is asking for an instance to the object.

Dim RegKey As RegistryKey = My.Computer.Registry.LocalMachine.OpenSubKey("HKEY_CURRENT_USERSoftwa reAnyDWGSoftwareDWGtoPDFProSettings", True)
RegKey.SetValue("OutputPDFFileOpt", 1)

Finally, I want to apply this setting to the program on four different computers (local, and three others on the network).

Reading And Writing To 64 Bit Registry?

Sep 20, 2010

I need to read a value (and possibly adjust the value) in HKLMSoftwareMicrosoftWindowsCurrentVersionUninstall key on both 32 and 64 bit systems.I've tried accessing 'stuff' by compiling my widget as both a 32 and 64 bit app, but nothing is working. Then I came across some information indicating that this could be done from a 32 bit applicaiton using KEY_WOW64_64KEY [URL] somehow, but I can't figure it out.

1) Check the existing value of HKLMSoftwareMicrosoftWindowsCurrentVersionUninstall{ProductGUID}DisplayVersion handling both architectures.

2) If the value <> "" And <> Our Current Version Then

3) Write the Current Version to the value mentioned in step 1.

I wouldn't think this is that difficult as I've worked with registry before, but the 64 bit stuff is throwing me for a loop.It would be nice if I could compile my app to target AnyCPU then detect where its running on 32 or 64 bit. The app could then look and update in the appropriate location.I currently am set to use .NET 2.0, but could go to 4.0 if there is something in there that makes the above tasks easier.

Writing To Registry In Win7?

Jan 30, 2012

I have looked through more old threads than I can count and I just cannot get any of the suggestions to work. I did a little poking around MSDN as well. I am trying to use the registry to enable AutoLogon on a Win7 machine through code. I can read the current value with no problem but I am running into security problems when I attempt to change AutoLogon to "1". This is what I have done so far.

System.UnauthorizedAccessException When Writing To Registry Key?

Nov 17, 2009

My application needs to change the default signature of outlook and I need to change the value of a registry key for this. But I get a error that I probaly don't have enough permissions. Strange thing is, if I change it manually it doesn't complain.

Error:System.UnauthorizedAccessException : Cannot write to the registry key.

Happens at the 2nd line:

vb
Dim subkey = Microsoft.Win32.Registry.CurrentUser.OpenSubKey("SoftwareMicrosoftWindows NTCurrentVersionWindows Messaging SubsystemProfilesOutlook9375CFF0413111d3B88A00104B2A6676�0000002") subkey.SetValue("New Signature", Text.Encoding.Unicode.GetBytes("Eigen"), Microsoft.Win32.RegistryValueKind.Binary)

VS 2008 Error Catching With Registry Settings

Nov 4, 2009

I'm editing some settings in the registry and then adding items to a ListView.

[Code]...

If I'm not mistaken, the code will not continue in the Try block if the first part fails and then move on to the catch statement, correct? I'm adding and deleting a bunch of different entries in the registry and the computers I've tried my app on so far, have not failed. So I'm not able to test if this method will work for error catching. If there's a better method, I'd appreciate the info.

File I/O And Registry :: Writing Structures To Disk

Oct 21, 2010

My application uses structures that contain strings and arrays that I want to write to disk. I understand that I can create the fixed length data types in the structures by using "ReDim" and "String$", but my question is: Does VB reallocate the storage for the structure which includes these redimensioned members in-line (which would be necessary in order to write the contents to disk), or does it allocate heap and merely store a pointer in the structure?If only a pointer is provided, is there a straightforward workaround to allow me to create fixed length data types in a structure that could be written to a disk file?Or, Is there an I/O method that will handle the situation by recreating a contiguous buffer containing the structure before writing it to disk?

File I/O And Registry :: Analyzing Contents And Writing Manipulated Data

Jul 25, 2009

I am basically reading a text file with info like this:
"S1($=""ChW System Pressure"",V=134.00,%=""Pa""),S2($=""UPS_Batt Rm 1to4 Circ A Flow "",V=9.17,%=""DegC""),S3($=""UPS_Battery Rm Sec ChW Rtn"",V=-38.38,%=""DegC""),S4($=""Buffer Vessel BV-02 High Temp"",V=9.08,%=""DegC""),...

And I'm trying to write a program that read the data, filters the sections so that per line it does the bit before the brackets i.e. "S1" then a comma then the sections inside the brackets as comma separated values removing the double quotes and symbols I don't want etc. Basically dividing the separate S*'s onto different lines and separating the values with comma's. There are also other points which are a different letter than "'S" and the same to do with them to.

File I/O And Registry :: Writing Generic FileSave Routine For Collections

Mar 12, 2009

I want to write a generic file saving routine where the routine is passed data in the form of a collection and it sets a containsStructure flag. I wanted to be able to save the data from the collection, but if it is a collection of structures I want to be able to extract the data from the structure to write to the file.

The only trouble is, that I cannot do something like:
For Each s As dataStructure In data
Next
Since the compiler complains that dataStructure is not defined. Is there a way to code around this?

File I/O And Registry :: Text File Reading And Writing?

I've attached what I would do in VB5. I have searched around, but all the examples I find use a Textbox instead of an array. Can anyone show me how I can do this with VB 2010?

Getting Error On Only 1 Computer (out Of Many) When Writing To DB

Jun 8, 2011

I have written a program to track the membership of a local gym that works perfectly on every computer EXCEPT the computer at the gym. I am pulling out my hair trying to figure out what the difference is any why ONLY that machine throws an error.

Background: The program is written in VB.NET (2008) and calls a MS Access db (PROVIDER=Microsoft.Jet.OLEDB.4.0;). The computer in question is a Vista machine that is extremely slow (I think it's a Celeron with 512 RAM).

History: I have tested the exe on a Windows 7 machine in 32bit and 64bit. Tested on a 2000 and 2003 server with 32bit and 64 bit processors. Testes on a Mac running parallels with XP. Tested on machines with Office XP, 2003, 2007 and machines without Office (thinking it was a resource that was missing) Every machine works but the Vista machine.

The error occurs when the program is trying to update an existing table with a new value that is valid. The field is set to text so I know it's not a casting problem. The error message is a general exception that reveals no information. I can continue from the error but it does not complete the change to the db.

One other interesting note is that the database is accessed across the network so multiple people can use the program at the same time. Unfortunately the Vista machine is the "server" and is the home for the db. The other machines are laptops and are not always accessible on the network. If the program and db are local to the laptops then the program works perfectly. If the db is accessed across the network and the program is local to the laptop then the program crashes.
