Get the filename in Javascript from input file tag in Internet Explorer
Step 1: Create the HTML File Input Element
To get started, you need an HTML file input element where users can select a file. Here’s an example:
<input type=”file” id=”fileInput” onchange=”getFileName()”>
The `onchange` attribute triggers the JavaScript function `getFileName()` whenever a file is selected.
Step 2: JavaScript Function for Internet Explorer
Internet Explorer has its own way of handling file inputs, and the File API used by modern browsers is not fully supported. Here’s a JavaScript function to extract the file name in IE:
function getFileName() {
var fileInput = document.getElementById(‘fileInput’);
var fileName = ”;
// Check if the browser is Internet Explorer
if (navigator.appName == ‘Microsoft Internet Explorer’) {
// Use ActiveXObject for IE
var filePath = fileInput.value;
var startIndex = (filePath.indexOf(‘\\’) >= 0 ? filePath.lastIndexOf(‘\\’) : filePath.lastIndexOf(‘/’));
fileName = filePath.substring(startIndex);
if (fileName.indexOf(‘\\’) === 0 || fileName.indexOf(‘/’) === 0) {
fileName = fileName.substring(1);
}
} else {
// For other browsers, use the standard File API
fileName = fileInput.files[0].name;
}
// Display the file name
alert(‘Selected file: ‘ + fileName);
}
This function checks if the browser is Internet Explorer using `navigator.appName` and then uses `ActiveXObject` to extract the file name. For other browsers, it relies on the standard File API.
Conclusion:
Ensuring compatibility with Internet Explorer is still a consideration for web developers, especially when dealing with file inputs. By incorporating the provided JavaScript function by Hire tech firms, you can get the filename in Javascript from input file tag in Internet Explorer.
Remember to test your implementation across multiple browsers to guarantee a smooth user experience for everyone.
In this blog post, we’ll explore how to open Excel files in a directory using Python 3, providing a step-by-step guide for beginners and experienced developers alike.
Prerequisites:
Before diving into the code, make sure you have Python 3 installed on your machine. Additionally, install the `openpyxl` library, a popular Python library for working with Excel files.
pip install openpyxl
Step 1: Importing Required Modules:
To begin, import the necessary modules in your Python script:
import os
from openpyxl import load_workbook
Step 2: Setting up the Directory Path:
Specify the path to the directory containing your Excel files. You can use the `os` module to navigate and interact with the file system.
directory_path = ‘/path/to/excel/files
Step 3: Listing Excel Files in the Directory:
Use the `os.listdir()` function to retrieve a list of files in the specified directory. Filter the list to include only Excel files (files with a `.xlsx` extension).
excel_files = [file for file in os.listdir(directory_path) if file.endswith(‘.xlsx’)]
Step 4: Opening Excel Files:
Loop through the list of Excel files and open each file using the `load_workbook` function from `openpyxl`.
for excel_file in excel_files:
file_path = os.path.join(directory_path, excel_file)
workbook = load_workbook(file_path)
# Add your custom processing logic here
workbook.close()
Step 5: Performing Custom Processing:
Within the loop, you can implement custom logic to process the data in each Excel file. This could include reading and modifying data, extracting specific sheets, or performing calculations.
for excel_file in excel_files:
file_path = os.path.join(directory_path, excel_file)
workbook = load_workbook(file_path)
# Custom processing logic
for sheet_name in workbook.sheetnames:
sheet = workbook[sheet_name]
# Perform operations on the sheet data
workbook.close()
Conclusion:
With this comprehensive guide from Hire tech firms, you can now effortlessly open Excel files in a directory using Python 3. The combination of Python’s simplicity and the `openpyxl` library’s functionality makes this task accessible for both beginners and experienced developers.

Python, a versatile and powerful programming language, provides robust mechanisms for handling errors and exceptions. When your code encounters an unexpected situation, it raises an exception to signal that something went wrong. Printing these exceptions with informative messages can be crucial for debugging and understanding the cause of the issue.
In this guide, we’ll explore how to print exceptions in Python with custom messages.
The Basics- How to Print as Exception in Python
If you want to catch and know how to print exceptions in Python, you can use the `try` and `except` blocks. Inside the `try` block, place the code that may raise an exception. In the corresponding `except` block, catch the specific exception and print a custom message.
Here’s a simple example:
try:
# Your code that may raise an exception
result = 10 / 0 # This will raise a ZeroDivisionError
except ZeroDivisionError as e:
# Print a custom message along with the exception
print(“Custom message: Division by zero”)
print(e)
In this case, the program attempts to divide 10 by 0, triggering a `ZeroDivisionError`. The `except` block catches this exception and prints a custom message along with the exception details.
Adding Traceback Information
To enhance your error messages, you can include traceback information, which shows the sequence of function calls that led to the exception. Python’s `traceback` module facilitates this. For example:
import traceback
try:
# Your code that may raise an exception
result = 10 / 0 # This will raise a ZeroDivisionError
except ZeroDivisionError as e:
# Print a custom message along with the exception and traceback
print(“Custom message: Division by zero”)
traceback.print_exc()
The `traceback.print_exc()` function prints the exception and traceback, providing a detailed context of the error.
Customizing Exception Messages
If you want to raise a new exception with a custom message, you can use the `raise` statement. Here’s an example:
import traceback
try:
# Your code that may raise an exception
result = 10 / 0 # This will raise a ZeroDivisionError
except ZeroDivisionError as e:
# Raise a new exception with a custom message and include the original exception
raise Exception(“Custom message: Division by zero”) from e
This technique allows you to create more informative and context-specific error messages.
Conclusion
Printing exceptions in Python is a fundamental skill for effective debugging. By combining the `try`, `except`, and `traceback` features, you can create detailed error messages that help you identify and fix issues in your code. Whether you’re a beginner or an experienced developer, mastering exception handling is key to writing robust and reliable Python code.

If you are looking for custom software services with budget or infrastructure constraints, offshore software development is your answer. Going for offshore hiring implies connecting with a global talent pool and getting premium software development services without exhausting your resources.
Offshore Development Services In Simple Words,
Mean hiring a team of remote developers from a different country that incurs less development costs in comparison to their home country. Businesses hire offshore developers to leverage the flexibility and cost-effectiveness of remote hiring while experiencing the quality and dedication of in-house developers.
The best part of this is that you get the flexibility to either hire developers with expertise in one area or build a team of developers to get comprehensive services. This is why companies of all sizes, from startups to established firms, hire dedicated offshore developers per their requirements.
The traces of digital transformation are evident in this new business model. With easy access to required tools, techniques, and advanced technologies for facilitated collaboration, management, and communication with remote teams, businesses are more willing to experience offshore software services.
But just like every digital advancement, offshore development services also come with benefits and challenges. So, let us explore how hiring offshore developers can help you expand your business, along with common challenges and how to overcome them for effective hiring.
Benefits of Offshore Hiring
There are numerous benefits of remote hiring. You do not have to update your infrastructure, worry about the lack of space, or incur any additional hiring costs. But other than that, there are many other reasons to hire an offshore developer.
Some of the benefits you get to leverage when you hire offshore developers
Cost-Effective Development
Developing custom software solutions can be really expensive, especially if you hire an in-house team of developers. Maintaining resources as well as investing in both digital and physical infrastructure can get challenging.
This is why, hiring an offshore developer and building a remote team can be a better option from a business perspective. It can be especially beneficial for non-IT businesses as they won’t have to invest in IT infrastructure as it is not their primary function either.
By hiring an offshore team, you can easily expand your team with remote developers who will offer top-quality solutions at a comparatively lower price.
A Diverse Talent Pool
In the present scenario, you do not have to rely only on your local talent pool for hiring someone who has the required skillset and doesn’t clash with the budget. With offshore development services, you can easily achieve that.
Offshore hiring implies you get to choose developers from across the globe and shortlist the ones that fit all your criteria. This also gives you access to designing software products that fit international standards and quality.
Additionally, when you hire offshore developers, you get to know about different market trends across different areas, thereby helping you create tailored solutions for your international clients as well.
Quicker Development With Offshore Developers
Though this one requires very thorough planning and active participation from every team member, if done well, it can really boost your business. When you hire in-house developers, you get limited working hours when your resources can work on the said project.
But with a team of remote developers working from different locations and time zones, you can continue the development round-the-clock, with different members taking up the project as per their working hours.
Doing so can benefit IT companies the most as they can design custom solutions based on newly found insights about the specific market, thereby giving them a better position in the market than their competitors.
Saves Time to Focus on Core Business Activities
Industries like hospitality, medicine, education, and other similar ones that require IT solutions merely to streamline their processes need not invest their resources in hiring and managing IT professionals and infrastructure.
They can consult with a reliable offshore software development service provider and let the experts handle the technology-intensive part while the rest of the organization can focus on optimizing their core business operations for effective management.
This way companies need to invest less in the services that are secondary to their services and yet maintain relevancy by staying technologically ahead of their competitors.
Business Growth
When you hire offshore experts, you not only get high-level expertise and premium solutions but also get a first-hand insight into the different markets, their cultures, and know about various trends.
This will help you understand what products and services may or may not work out in different countries. You can even add or subtract certain features to design solutions in sync with the technical knowledge and adeptness of the people of a particular region.
So you can make mindful data-based decisions and not just rely on the guesswork of what may or may not work, thus saving your resources while increasing the revenue and leading to the company’s growth.
Challenges Involved in Offshore Hiring
Offshore hiring is now building its stronghold in the business realm because of all the benefits offered. But very rarely do we draw our attention to the challenges that often show up when you are in the middle of the hiring process or have already hired the offshore developer.
We have listed down some of the common pitfalls that you might encounter along with the best practices that can help you overcome them. This will help you streamline and facilitate remote hiring and maximize its benefits for your business.
Here are some of the top challenges that surround offshore software development
Challenge #1 – Communication and Language Barriers
Language plays a major role in facilitating effective communication across the whole organization. It can become the biggest barrier in software development as it can lead to misinterpretation and miscommunication
To foster clear communication and an effective development journey, ensure that there is one common language that both you and your team are familiar with. The most preferred language is English. This is especially required when you are hiring from countries with a different native language than yours.
Also, you can document the necessary information as tables, flowcharts, and documents to break down complex ideas and make it easy for everyone to understand.
Challenge #2 – Cultural Differences
Do you know that taking an afternoon nap is acceptable in Japan and in France, employees are expected to disconnect from work after their work hours are over, while in South Korea, it is expected that employees work for longer hours.
As much as it is fascinating to witness different work cultures, it can become one of the biggest obstacles when you hire offshore developers for your organization. Team members hired from varied geographical locations can have different work approaches and ethics which if not addressed early on, will create an awkward work environment.
To overcome this challenge it is essential to create awareness among employees about different work cultures and promote an active discussion between them about it. This will help them understand and accept the different nuances and be more considerate of each other’s work approach.
Challenge #3 – Multiple Time Zone
Remote hiring means multiple locations and their different time zones will pose a major challenge as every team member will be working as per their working hours. In most cases, this time gap affects communication, decision-making, and overall project progress.
To mitigate this challenge, it is essential that you carefully plan, communicate and divide the work among team members in a way that it minimizes the time gap between them. You can also choose the locations in a way that your and the team’s working hours overlap as it will increase the chances of having real-time communication.
Also, using cloud-based project management tools can also facilitate clear communication by centralizing the channels and facilitating collaboration. Offshore software development is an amazing option for round-the-clock development as well, provided you competently manage the remote team.
Challenge #4 – Data Security
One of the major hindrances in adopting offshore hiring is the fear of data breaches. This is a serious concern as well, for data is considered the most important element for a business to succeed. Also, these documents might also contain sensitive information which if made public can lead to far worse outcomes.
This is why it is advised to hire dedicated offshore developers from reliable sources and ensure that all the legal formalities, including, signing necessary documents are fulfilled.
To Sum Up
Any form of hiring whether it is offshoring or in-house, comes with its own package of unexpected surprises. While you can’t predict everything, being prepared about certain common things can make the process seem a lot less like an adventure and more like an experience.
And it goes without saying that connecting with a reputable source to hire offshore developers can take away the bulk of the burden off your shoulders. So, we as hire tech firms hope that these points will bring you clarity so that you can hire the best talent and expand your business beyond your own expectations.
