I have a program with an associated file type. However, when I double-click a file to launch the program, I can't figure out where that path was passed to the program.
Initially I thought the file path would be in Environment.CommandLine, but the command line only contained the program path.
I specified the file association using the Publish Options in visual studio like so: extension: .ext, Description: Some File, ProgId: ProjectName, Icon: SomeIcon.ico.
You are right, it should indeed be passed as a command line argument and be available through Environment.CommandLine.
My guess is that something is wrong with the file association itself. Here is a dated but still useful TechNet article on how these things work. In particular, the "%1" in the screenshot below is essential.
I'm not sure about the DDE thing, so if you're not using it, turn it off.
As a guess, your file type association may not be configured properly. If you look in the registry at your "Open" command for your file type, the command is probably configured as "c:\your-company\your-app.exe", instead of as "c:\your-company\your-app.exe" "%1", which is what it would need to be if you wanted the file path to show up on the command line.

I have a single command line windows executable that has many options built into this exe file.
Eg:
(It can take screenshot)
ToolGo.exe printscreen c:\temp\filename.jpg yyyymmdd
(It can show up)
ToolGo.exe showIP machineA
I want to write another command line application, possibly in .net , where it can embed/build a wrapper around this ToolGo.exe file into my application without the user be able to use the ToolGo.exe, and also users can only access one function of this main exe file.
In the example I want this other tool to access only the print screen function in this new exe file.
The new application will have this:
Tool2go.exe printscreen c:\temp\filename.jpg yyyymmdd
But if someone types the following, it will not work:
Tool2go.exe showIP machineA
Or
ToolGo.exe showIP machineA
Any ideas how I can write this code to do this in a .net command line application?
This is a multi-part question, so I'll just give the main part of the issue as the answer with suggestions on handling the rest.
You can embed a .exe into your program by clicking on Properties and navigating the the Resources section, and adding that .exe to it.
After that, it's just a matter of extracting it locally so you can pass your commands to it, and handle it's responses. (I'm not really aware of any way to do so w/out first extracting the. exe; the .exe itself needs to run somehow after all).
To extract the embedded .exe, you do this:
' Extract the MyProgram resource (i.e. your .exe)
Dim b() As Byte = My.Resources.MyProgram
' Write it to the user's Temp folder
File.WriteAllBytes(Environment.ExpandEnvironmentVariables("%TEMP%\MyProgram.exe"), b)
By extracting it to the user's Temp folder, you can pass it your commands, and since it's 'out of sight' the user probably won't even know it's there to directly use it themselves, unless they're a bit more advanced and visit their Temp folder often. You can slightly help to avoid this, but extracting the .exe when your program starts, and then deleting it when it exits, so it only exists on the user's system while your program is running.
As far as what the user can and cannot type in order to pass to the program, you can simply handle the filtering with your program; since your program is the one passing the commands to the .exe, just don't pass any commands that you don't allowed, and pass the ones you do want allowed.
Is it possible to get the actual file, or the file that gets copied from version control to a location?
This sounds confusing. Basically I have the file path of the version controlled file, but I need an actual path to the file because I need to make a cconsole command using powershell.exe. The file will look something like this
$/MyTeamProject/MyProject/Development/MyPowershellScript.ps1
Now, I am looking for a vb expression to see if I can get the actual file and make call the powershell.exe command from console. Any thoughts?
You may use VersionControlServer.GetItem(String path) to obtain a reference to the Item. Then use Item.DownloadFile() or Item.DownloadFile(String localPath) to copy the file locally. I have a variation of this that creates a shipment based on multiple changesets.
I have a large batch of assorted files, all missing their file extension.
I'm currently using Windows 7 Pro. I am able to "open with" and experiment to determine what application opens these files, and rename manually to suit.
However I would like some method to identify the correct file type (typically PDF, others include JPG, HTML, DOC, XLS and PPT), and batch rename to add the appropriate file extension.
I am able to open some files with notepad and review the first four bytes, which in some cases shows "%PDF".
I figure a small script would be able to inspect these bytes, and rename as appropriate. However not all files give such an easy method. HTML, JPG, DOC etc do not appear to give such an easy identifier.
This Powershell method appears to be close: https://superuser.com/questions/186942/renaming-multiple-file-extensions-based-on-a-condition
Difficulty here is focusing the method to work on file types with no extension; and then what to do with the files that don't have the first four bytes identifier?
Appreciate any help!!
EDIT: Solution using TriD seen here: http://mark0.net/soft-trid-e.html
And recursive method using Powershell to execute TriD here: http://mark0.net/forum/index.php?topic=550.0
You could probably save some time by getting a file utility for Windows (see What is the equivalent to the Linux File command for windows?) and then writing a simple script that maps from file type to extension.
EDIT: Looks like the TriD utility that's mentioned on that page can do what you want out of the box; see the -ae and -ce options)
Use python3.
import os,re
fldrPth = "path/to/folder" # relative to My Documents
os.chdir(fldrPth)
for i in os.listdir():
with open(i,'r') as doc:
st = doc.read(4)
os.rename(i,i+'.'+re.search(r'\w+',st).group())
Hopefully this would work.
I don't have test files to check the code. Take a backup and then run it and let me know if it works.
My problem should be plain and simple to solve, but google is not helping me today.
I need to read/write a configuration file (config.xml) and, as i see so much problems with permissions with special folders, i decided for myDocuments.
Now, from File system (Setup), I added a custom special folder (myDocuments)
added a subfolder (g1OKweb) inside myDocuments
added the file (config.xml) inside g1OKweb
What I expect, reading around, is that during the installation g1OKweb should be created if not existing or older, and the same for config.xml, but it isn't.
Does someone have any clue?
Thanks in advance
Use Directory.CreateDirectory to create the directory before attempting to access the file. This will automatically create all parts of the path that do not yet exist. If the full path already exists, it will do nothing.
When opening the file, use a FileStream constructor overload that allows you to specify FileMode.OpenOrCreate. This will succeed regardless of whether the file already exists or not.
When you have opened the file, check to see if it is empty before parsing it. If it is empty, insert your XML root element first.
Does anyone know how to get hold of the path to the directory where the LINQPad script file (.linq) resides?
Or to the script itself for that matter.
Note that I'm not talking about the location of the "My Queries" folder, the one shown inside LINQPad.
I can save a .linq file anywhere on disk, and open it by double-clicking on it.
For instance, if I save the file to C:\Temp\Test.linq, and execute the program, I'd like to have either C:\Temp or C:\Temp\Test.linq.
Basically I'd like something akin to Environment.CurrentDirectory or Assembly.GetEntryAssembly().Location, just for the .linq file.
Things I've tried:
Looking through environment variables
Looking through the LINQPad assembly that is given to my script
Throwing an exception and looking at the stacktrace (contains a link to a temporary copy of my script somewhere else)
Environment.CommandLine.Dump(); - gives LINQPad executable
Environment.CurrentDirectory.Dump(); - gives C:\windows\system32
Assembly.GetExecutingAssembly().Location.Dump(); - gives temp directory
I've just added a feature to address this. You can test it now by downloading the 2.27.1 or 4.27.1 beta build.
To get the current query's folder, use the following expression:
Path.GetDirectoryName (Util.CurrentQueryPath)
I presume you mean programatically and not through the UI itself.
The path to the linq file directory is held in
%APPDATA%\LINQPad\querypath.txt
The next question after "How do I get LinqPad script directory" is "How do I set it?" below is how you do it and link to where I found the answer
Directory.SetCurrentDirectory (Path.GetDirectoryName (Util.CurrentQueryPath));
