I am writing a program in pure C, using win32 api.
I need to know the full path of a registered program.
For example if I write
ShellExecute(0,0,"chrome",0,0,SW_SHOW)
the chrome browser starts. How can I obtain "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" from "chrome" as ShellExecute does?
In this case Chrome has registered itself in the App Paths registry section. More details over on MSDN: https://msdn.microsoft.com/en-us/library/windows/desktop/ee872121.aspx
Finding an Application Executable
When the ShellExecuteEx function is called with the name of an
executable file in its lpFile parameter, there are several places
where the function looks for the file. We recommend registering your
application in the App Paths registry subkey. Doing so avoids the need
for applications to modify the system PATH environment variable.
The file is sought in the following locations:
The current working directory.
The Windows directory only (no subdirectories are searched).
The Windows\System32 directory.
Directories listed in the PATH environment variable.
Recommended: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths
The documentation tells you how the shell searches, and you can replicate that search.
The function SHEvaluateSystemCommandTemplate does exactly that. It performs the exact same search algorithm that is performed by ShellExecute. You just pass "chrome.exe" (or even just "chrome"), and the full path to the chrome executable is returned in the ppszApplication parameter.

I have Python 3.10.7 with the follwing packgaes installed using pip install in command line:
behave 1.2.6
selenium 4.4.3
These have also been added to the packagelist of the project using the project config in pycharm
Also behave is in the systme path as well along with python.
I am trying to use the behave command but I am getting the following error:
behave : The term 'behave' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
At line:1 char:1
+ behave features\myfeaturefile.feature
Following is my project directory:
Following is my project in pycharm:
I need help in fixing this problem as I am new to this tool. Thanks
First check if you have behave and python in the path variables.
Check if you can execute the below command
C:\demo>behave -h
If this does not return a list of help commands associated with behave, this means that behave is not in the path variables
Alternatively, you can check it via cmd using the "PATH" command. This will show you all the entries in the system path
C:\demo>PATH
PATH=C:\Program Files (x86)\Microsoft SDKs\Azure\CLI2\wbin;C:\Program Files\AdoptOpenJDK\jdk-11.0.11.9-hotspot\bin...
If behave or python are not in the path variables, you can set them using
set PATH=%PATH%;c:\PATH_TO_BEHAVE
NOTE: Setting path using cmd is only valid till the time the cmd window is open. Once you close it, the path variable will be rest to original values.
Behave, along with a few other .exe files is sitting in the:
C:\Users\chauhany\AppData\Roaming\Python\Python310\Scripts
As per your instructions #Manish Agarwal, I added the C:\Users\chauhany\AppData\Roaming\Python to the PATH from the command line and re-started the machine. But it didn't help. I then moved the behave.exe from the above location to my python 3.10 directory which is sitting in C:\Program Files\Python310 and python is in the system path, and restarted my machine again.
I then deleted and recreated my project with the new feature file (same directory structure).
If I now run the same command, that is, features\myfeaturefile.feature from
C:\Users\chauhany\PycharmProjects\martechBehaveProject>
I get a FileNotFound error
So I went to the folder where the file is actually sitting that is:
C:\Users\chauhany\PycharmProjects\martechBehaveProject\features\steps> and then re-ran the command and it worked.
I was under the impression that if you have just one feature file you don't have to specify the actual feature file and it can be run from anywhere in your project i.e., from any location which certainly is not correct.
I'm working with selenium. The script is in :
C:\Users\User\Desktop\Data Analytics Arg\Proyectos\datademia\Py_install\py_ejemplo.py . Venv is activated and chromedriver.exe is in C:\Users\User\Desktop\Data Analytics Arg\Proyectos\datademia\Py_install\chromedriver.exe
The script runs perfectly. Then I created an only .exe-file via terminal :
pyinstaller --add-data "chromedriver.exe;." --windowed --onefile py_ejemplo.py
Folders are created correctly (build and dist). The .exe file (py_ejemplo.exe) was created, but when I try to run it, I get this message:
I've been looking and still can't solve it... I've tried these solutions :
filenotfound
but didn't work for me...Could someone help me? I don´t know what's wrong...
Thanks in advance
I got the same problem but I was working with Firefox and geckodriver.
In my case, I copied the selenium folder from the virtual environment to the dist folder and it worked.
There are a few things you should ensure when packing a script with pyinstaller build with selenium web driver.
It may require to add driver executable when building. I.e. chromedriver.exe
It may also require to add some package files related to selenium such as getattributes.js file when building. It was required at my project.
pyinstaller will extract those files to temp folder in AppData for windows users. So in your code, your relative paths may require to be resolved with a sample function as below (if you are running your code in vs code or you are running through pyinstaller executable the paths should be resolved by function).
For item 1 and 2, you can use --add-binary and --add-data features of pyinstaller for each of them. It is also possible to do this in *.spec file with add-files list, following your first running of pyinstaller (see this explanation) I preferred command-line option as below.
pyinstaller ./app.py --onefile --noconsole --add-binary "./driver/chromedriver.exe;./driver" --add-data "C:\Users\YOUR_USER_NAME\.conda\pkgs\selenium-3.141.0-py38h2bbff1b_1000\Lib\site-packages\selenium\webdriver\remote;selenium\webdriver\remote"
For item 3, to resolve relative paths in your source code, you can use below function in related places (for example when accessing chromedriver.exe)
def resource_path(relative_path):
try:
base_path = sys._MEIPASS
except Exception:
base_path = os.path.dirname(__file__)
return os.path.join(base_path, relative_path)
Use above function once you need to access packaged executables and files in your source code. In below example, my chromedriver is inside driver folder in my workspace. But when it is accessed through pyinstaller executable, it will be extracted to temp folder in AppData, yet function will access it through sys._MEIPASS variable set by pyinstaller.
driver = webdriver.Chrome(executable_path = resource_path('./driver/chromedriver.exe'))
Hope it works.
I have clone a git repository in C:/Repo. I am trying to open a file which lies in the git at some location ,for example, git/program/slm/error.txt. I am using fopen() API in C language to open the file and the filepath I am specifying is "C:/Repo/git/program/slm/error.txt". The program seems to be working while providing the above mentioned path. But,I want to make this program generic so that it can work on other systems as well as in other systems it is not necessary that the git will be cloned in C:/Repo only,this is local to my system. git/program/slm/error.txt is the relative path and will be common for all the system.
Can anyone please help me how what filepathname should I provide to make it generic so that it works on all the systems?
Take your repository path as commandline argument and then when you want to access the file append the repository path and the relative path that you want to access.
I have an inno setup code which works fine. Can anyone tell me how to make a bat file from an inno setup code so that a single click will initiate the installation set up.I have done that for java class files.Any help is appreciated.
There should be no need for a .bat file. Inno Setup creates a stand-alone executable (by default named Setup.exe) that you can simply double-click like any other Windows executable.
The executable it creates is nameable either by renaming the Setup.exe to a different name (YourAppSetup.exe, for instance) manually, or by using the OutputBaseName value in the [Setup] section. You can control where the setup executable is created by using the [Setup] section value OutputDir. Here's an example, from the CodeExample1.iss' sample provided in yourInno Setup` installation:
[Setup]
AppName=My Program
AppVersion=1.5
DefaultDirName={code:MyConst}\My Program
DefaultGroupName=My Program
UninstallDisplayIcon={app}\MyProg.exe
InfoBeforeFile=Readme.txt
OutputDir=userdocs:Inno Setup Examples Output
This creates the default Setup.exe in the userdocs: (your My Documents folder), in a subfolder named Inno Setup Examples Output. To put it somewhere else, just change the OutputDir entry to a different location. For instance, to put it in a sub-directory of your source folder named Installer, just use
OutputDir=Installer
For more info, see the documentation, in the Setup Script Sections->[Setup] Section Directives branch.
To change the name from Setup.exe to something else, add a new entry:
OutputBaseName=MyAppSetup
I'm making a filesystem using FUSE, and know I have a doubt. When I use the "cd" command in the new filesystem, it changes to directories that doesn't exist.
For example, if the directory "m" doesn't exist, and I make a "cd m" it changes to that directory.
Which is the function that FUSE calls when the directory is changed? Why is the app doing the problem I describe?
Thanks!
Are you implementing getattr? and if so, are you making sure to return -ENOENT if the path they give you doesn't correspond to a file or directory in your system?
