I have a small problem that I'm sure has a simple solution, although its only simple when you know how.
Using Windows8, I want to register my COM dll. I'm doing this via a .reg file. The problem comes with adding the InprocServer32 entry. For some reason the value that will point to my .dll file doesn't actually get added into the registry. The InprocServer32 key gets added but not the value.
I have this entry within the .reg file...
[HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{15C9923A-7847-4249-95C5-E521D8D614C9}\InprocServer32]
#="D:\COMTest\TestIObject.dll"
"ThreadingModel" = "Both"
There are several other entries that get added correctly, just not the 'value' of the InprocServer32. The ThreadingModel key and value are added as expected. Is the 'InprocServer32' key value protected against being added/changed in Windows8? If so what would be the correct solution?
You need to escape the backslash characters in the path:
#="D:\\COMTest\\TestIObject.dll"

I'm trying to see every file is a certain directory, but since each file in the directory is very large, I can't use sc.wholeTextfile or sc.textfile. I wanted to just get the filenames from them, and then pull the file if needed in a different cell. I can access the files just fine using Cyberduck and it shows the names on there.
Ex: I have the link for one set of data at "name:///mainfolder/date/sectionsofdate/indiviual_files.gz", and it works, But I want to see the names of the files in "/mainfolder/date" and in "/mainfolder/date/sectionsofdate" without having to load them all in via sc.textFile or sc.Wholetextfile. Both those functions work, so I know my keys are correct, but it takes too long for them to be loaded.
Considering that the list of files can be retrieve by one single node, you can just list the files in the directory. Look at this response.
wholeTextFiles returns a tuple (path, content) but I don't know if the file content is lazy to get only the first part of the tuple.
Salt has a state module to manage .ssh/authorized_keys
https://docs.saltstack.com/en/develop/ref/states/all/salt.states.ssh_auth.html
I am not happy with it, since it combines code and data.
The state file is for me some kind of source code.
The ssh-key is for me data.
I don't want to combine both in one file.
Is there an other solution which separates code and data?
you don't have to put them together in one file:
as per documentation: https://docs.saltstack.com/en/latest/ref/states/all/salt.states.ssh_auth.html
you can use this method:
thatch:
ssh_auth.present:
- user: root
- source: salt://ssh_keys/thatch.id_rsa.pub
- config: /%h/.ssh/authorized_keys
(contrary to the example in the documentation, i get an error if the config: value starts with a '%')
this keeps your keys in their appropriate files and only links them from your code by their filenames.
Please have a look at the OpenSSH Formula. openssh/auth.sls contains the code for a state that pulls all data from a pillar. In the root folder of the formula you find pillar.example that shows how to structure the data for a pillar.
Maybe this formula is a starting point for you.
I have used a dialog in OnFirstUIBefore() for users to input some information,
and stored them in property USERINF.
However, when I want to retrieve the value of USERINF inputted by user in feature_installed(),
what I get is a default value.
I have added the USERINF to SecureCustomProperties property, but still cannot get the modified value.
How can I fix the problem?
I've always written values like these to the registry, then used appsearch to get them out into the property again.
There is no built in way to persist values like these built into MSI.
I have a working WiX installer that correctly writes properties to certain INI files, which works fine, but I have a need to generate the name of an INI file on the fly, from the computer name, eg.
MACHINE(xxx).INI
where xxx is my computer name.
I have tried all sorts of combinations of properties and I just can't seem to get it working. Can anyone put me right ?
This is my latest attempt that doesn't work:
<Property Id="MACHINEINI" Value="MACHINE([%COMPUTERNAME]).ini" />
...
<IniFile Id="IniPermissions"
Directory="MYDIR"
Action="addLine"
Name="[MACHINEINI]"
Section="[ComputerName]"
Key="Permissions"
Value="TEST" />
I never see the value of MACHINEINI, as the filename that gets created is actually called
[MACHINEINI]
The value it writes in is correct, so I see the contents as follows:
[xxx] Permissions=TEST
(where xxx is my machine name)
I have tried using [ComputerName], [COMPUTERNAME], [%COMPUTERNAME]
When I build the installer, I get the following error:
C:\Source\blah\BLAH.wxs(50) : warning CNDL1077 : The 'MACHINEINI' Pro
perty contains '[COMPUTERNAME]' in its value which is an illegal
reference to an other property. If this value is a string literal,
not a property reference, pl ease ignore this warning. To set a
property with the value of another property, use a CustomAction with
Property and Value attributes.
The underlying Windows Installer table doesn't support this. Note that the FileName column is of type FileName. Only the Formatted type can take a [PROPERTY].
IniFile Table
You could need a custom action to write temporary records to the IniFile table to transform the file name. The advantage versus using a custom action to literally write the INI file is that rollback would be automatically handled for you.
It's not possible to tell you how to do this exactly since I don't know what language you'd want to use to write the custom action.
A simpler approach (from the installers perspective) would be to transform the [KEY] name inside a single INI instead of writing to different INI files.
i want my program to ask user "Do u want to set .mp3 file type always default open by this program?" (for first time only) any example to do this?
First, you will need to familiarize yourself with the Windows Registry.
Associations between programs and extensions are handled inside the HKEY_CLASSES_ROOT key.
Each extension appears as a sub-key.
As each key's default value you will find the associated key that handles most of the operations, currently supported, for that particular file type.
For example, you might find the .mp3's default value is set to "WMP11.AssocFile.MP3" or perhaps it set to "VLC.mp3", if you have installed VLC and configured it as the default MP3 player.
So, now you need to locate that key, again, inside HKEY_CLASSES_ROOT.
Although this may vary, you should find that "VLC.mp3" (or whatever key was associated with the .mp3 extension) has a sub-key called "shell".
Under "shell" you will find another sub-key called "Open".
And, finally, under "Open" you will another sub-key called "Command".
The "Command" key is the one containing the information used by Windows (and other programs) to open/start whatever application is currently associated with the ".mp3" (or any other) extension.
Once you understand and feel comfortable with the way associations are handled in the Registry, you should then use .NET's Microsoft.Win32's Registry class to navigate and query the required keys and their values.
Here's a very basic illustration of how the code would look like:
Dim mp3 = Registry.ClassesRoot.OpenSubKey(".mp3")
Dim associatedValue = mp3.GetValue("")
Dim associatedKey = Registry.ClassesRoot.OpenSubKey(associatedValue)
Dim defaultProgram = associatedKey.OpenSubKey("Shell\Open\Command").GetValue("")
MsgBox("MP3 Files Are Opened Using: " + vbCrLf + defaultProgram)
Hope this helps...
You need to set file associations. See this article on Code Project on setting File Associations in VB.NET.
An error shows up again after importing and declaring it like
Dim rgText As Registry.ClassesRoot.OpenSubKey(".txt")
and the error looks like this:
Type 'Registry.ClassesRoot.OpenSubKey' is not defined.
