Platform-dependent.
How do you populate values of combobox using server side scripting as php?
I am assuming you already have a mysql connection function/string in placeNow select the databasemysql_select_db("db_name"); // Put the name of your database in place of db_name// Add the column you want data from in place of ID// Add the name of your table in place of table_name$query = mysql_query("SELECT ID FROM table_name");// This gets a bit complicated but it helps with debugging?>Select an option
What is ComboBox in Visual Studio?
ComboCox is a drop down list which can editable ot not. Usually people use it to give a user predefined choices.
Why is a combo box different from a list box?
A combobox holds a single value, the user selects that value by clicking on an arrow on the side of the box (Right by default) and chooses from a drop down list of values, which closes again when a value is selected. A listbox allows the user to select multiple values (Or a single value if specified) from a constantly displayed list of values. In the new Windows Presentation Foundation (WPF) a listview can be configured to contain controls and images and is often used to display data to the user in a completely customised fashion (Such as a twitter feed with images); A combobox would not be suitable for this purpose.
I need to set the SelectedItem of a ComboBox to the first string in the collection. I use VB.NET. What code do I need?
The integer for the first string in the collection is zero. The code is shown below: Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load ComboBox1.SelectedItem = ComboBox1.Items.Item(0) End Sub
How do you disable one combobox by selecting some values in another combobox using java script?

What is rapid prototyping?
Rapid prototyping is the speedy creation of a full-scale model. The word prototype comes from the Latin words proto (original) and typus (model). It is a group of techniques used to quickly fabricate a scale model of a physical part using three-dimensional computer aided design (CAD) data. Construction of the part is usually done by using 3D printing or "additive layer manufacturing" technology. Recently I have taken the services from Iannone 3D, who provides Rapid Prototyping and a reliable FDM 3D printing service in the New Jersey area.
How did Nazi Germany prepared for operation Barbarossa?
Firstly, Operation Barbarossa was known as the Invasion the the USSR. Operation Barbarossa started in June 22nd 1941. This of course started war on the Eastern Front. How Hitler prepared Nazi Germany for Operation Barbarossa is both Unusual planning but also Quite amazing. On December 5th 1940, Hitler received Military Planned on the Invasion of the USSR. This plan include -4 Panzer divisions would be used as Spearheads along with 4.5 million Infantry and 1,000 Aircraft, Also use 7,000 Artiller pieces which indluded 550 Anti-Tank guns. -The Main strategy was to Use the Blitzkrieg campaign which had a tremendous effect on France and Britain on the Following year. -Send Planes on spy missions withing deep of the soviet union (From occupied Poland to as far as Moscow. -Try to stable a Friendlyier relation with the Soviets All of this had a Huge involvement in How Nazi Germany prepared for operation Barbarossa. The 4 Panzer groups used during operation Barbarossa were: 1st Panzer Army - Lead by Colonel General Ewald von Kleist 2nd Panzer Army - Lead by Colonel General Heinz Guderian 3rd Panzer Army - Lead by Colonel General Hermann Hoth 4th Panzer Army - Lead by Colonel General Erich Hoepner Once Hitler ordered to start the Invasion, The Invasion plan was to attack 3 areas; Army Group North, Army Group Cental and Army Group South Army Group North and South had 1 Panzer Group each. North had Panzer group 1 and South had Panzer Group 4. Army Group Central had Panzer 2 and 3 groups. Army Group North First Goal was to conquer Lennengrad. Army Group Central First Goal was to Conquer Moscow Army Group South First Goal was to Conquer both Keif and Adonet Bason At the start before the invasion of the USSR, Only German Feild Marshals and Staff officers along with Infrantry was sent to the Front and Order Armed vehicles near west, so it made it look like that Germany was planning to Invade Britain and not the Soviet Union and Tanks would of been placed on the evening of the invasion. Once Operation Barbarossa started Hitler sent 127 divisions to Invade, Most of them was Infantry Divisions of 145,000 each with 100 tanks in Support
Which is better adonet or aspnet?
When exploring the realms of .NET technologies, ADO.NET and ASP.NET stand out as critical components, yet they serve distinctly different purposes. This article dives into the core functionalities of both, providing a clear understanding of their roles in software development. ADO.NET is an acronym for ActiveX Data Objects .NET. It's a part of the Microsoft .NET Framework, offering a rich set of components for database interaction. Primarily, ADO.NET is designed for data manipulation - from retrieving to updating data in databases. It supports disconnected data architecture, meaning data can be accessed and manipulated without a constant database connection. This model significantly improves performance, especially in web applications where resource utilization and efficiency are paramount. ADO.NET includes classes like DataSet, DataTable, and DataView, which are integral for handling data within .NET applications. On the other hand, ASP.NET is a web application framework developed by Microsoft. It allows developers to create dynamic web applications and services. ASP.NET is not limited to script languages and supports .NET languages like C# and VB.NET, offering a robust and scalable environment for building web applications. It's a part of the larger .NET ecosystem, providing tools and libraries that enable developers to create sophisticated web interfaces, APIs, and services. Comparing ADO.NET and ASP.NET is akin to comparing tools designed for different aspects of building software. While ADO.NET focuses on data interaction, ASP.NET is geared towards creating the web interface and business logic of applications. In real-world applications, these technologies often work in tandem. ASP.NET creates the front-end, handling user interactions and requests, while ADO.NET manages the data transactions, serving as the bridge between the application and its data sources. The choice between ADO.NET and ASP.NET doesn't really apply as they are not alternatives to each other but rather complementary technologies. A full-fledged web application would typically use ASP.NET for its web interface and business logic, relying on ADO.NET for efficient data handling and operations. This synergy allows for the creation of efficient, scalable, and robust web applications. In summary, ADO.NET and ASP.NET are both integral parts of the .NET framework but serve different purposes. ADO.NET excels in data management, offering tools for efficient database interactions, while ASP.NET provides the framework for building web applications. Understanding the distinct roles of each technology is crucial for developers working in the .NET environment, ensuring the right tools are used for the appropriate tasks in the software development process.
