Hello, I'm new to PowerShell, so the answer may be staring me in the face I'm building a script to modify various registry entries using a. The environment is a Win 7 environment, with PowerShell 3. I'm stuck on properly creating the values for binary entries. Create an array using a. Value new-itemproperty -path 'HKCU: However, if I run the new-itemproprty cmdlet with the -value property discretely entered as 00, I presume my error lies in the properties of the.
I'd like to expand the base script to additional registry keys, so I need to make sure I get values to populate properly from the array properties. Am I missing a blatant conversion step, or is my issue more subtle?
The issue is due to the data type from the csv file. The binary data is being stored as a string and when you write the value to the registry key the sting is converted to a byte data type. Value from a string to a CharArray. I can create the value directly with the cmdlet I've seen a couple of different iterations of the example you found some with parentheses as yours shows, others with bracket and they all throw errors, bracketed attempts give positional parameter errors or improper value format errors, depending upon how it's bracketed.
Those enclosed in parentheses throw expression errors. If I change the values in my input file to "0x00,0x00"-the script throws "Cannot convert value "0x00,0x00" to type "System.
If I run the cmdlet manually with the value as indicated in your example Including the value as 00,00 also works if entered in the example format. Additionally, simply including the value as 00,00 with type binary without the [byte] statements also works. Jonathan actually gave you a far more useful answer than me, and taught me something in reading it myself. Thanks for the input Jonathan Your cause is pretty much what I suspected Here is some helpful info about what you see when you look at the registry key http: Still no love using any of the methods It appears that if the input to -Value is evaluated to a single instance of 00,00, it is output as a single 0.
I did find a workaround for the specific case of 00,00 as the input for a binary registry value that should output to 00 00 in the registry I simply added a column to my csv and separated the instances of Now the csv looks like this: I know this is a limited solution, so please, any additional info would be appreciated and I'll keep digging as well Here's what I would do: Test out some example strings you find on the internet, For Example " 0x00,0xFF ".
Put it in a variable and try to convert it, once you've converted it successfully and pipe it to get-member to see if it's what you want. It's very possible that my original premise is incorrect For now, I've got a short-term solution that can be deployed for the point problem and similar problems that will give me the breathing room to build a more complete and correct long-term solution October 15, at 4: Here's the code-everything seems to work, except that the value is not as expected Thanks for any help!
