Because Office does not display the Developer tab by default, you must enable it by using the following procedure:.

Almost any formatting or editing change that you can do by hand, can be done Beste Spielothek in Rabenwald finden VBA. To communicate with the serial port using Visual Basic, the MsComm control must be utilized to allow serial data transfer via a serial port Com1-Com4. How to send email from VB.

For example, the "GO" command outputs to port A, the integer value position. If the position is a variable , a string to set the port to the value of this variable would look like; MSComm1.

You may be many question how to communicate with microcontroller ,So, we can use concept on above to apply in your project ,process for communicate is like my exemple programming but you will be know protocol of those device.

Serail Port Project Page. VB Communication. This programming guide assumes the user has a basic knowlege of Visual Basic programming.

The teaching method used is to show a basic example of a VB6. To communicate with the serial port using Visual Basic, the MsComm control must be utilized to allow serial data transfer via a serial port Com1-Com4.

MSComm is a custom control shipped with VB5. Copyright c thaiio. Contact webmaster : webmaster thaiio. Here, the new name for the file is a parameter for the SaveAs method.

You use the same syntax to set a property that you use to read a property. The following code executes a method to select cell A1 in Excel and then to set a property to put something in that cell.

The first challenge in VBA programming is to get a feeling for the object model of each Office application and to read the object, method, and property syntax.

The object models are similar in all Office applications, but each is specific to the kind of documents and objects that it manipulates.

In the first line of the code snippet, there is the Application object, Excel this time, and then the ActiveSheet , which provides access to the active worksheet.

After that is a term not as familiar, Range, which means "define a range of cells in this way. In other words, the first line of code defines an object, the Range, and runs a method against it to select it.

The result is automatically stored in another property of the Application called Selection. The second line of code sets the Value property of Selection to the text "Hello World", and that value appears in cell A1.

The simplest VBA code that you write might simply gain access to objects in the Office application that you are working with and set properties.

For example, you could get access to the rows in a table in Word and change their formatting in your VBA script. That sounds simple, but it can be incredibly useful; once you can write that code, you can harness all of the power of programming to make those same changes in several tables or documents, or make them according to some logic or condition.

For a computer, making changes is no different from making 10, so there is an economy of scale here with larger documents and problems, and that is where VBA can really shine and save you time.

Now that you know something about how Office applications expose their object models, you are probably eager to try calling object methods, setting object properties, and responding to object events.

To do so, you must write your code in a place and in a way that Office can understand; typically, by using the Visual Basic Editor.

Although it is installed by default, many users do not know that it is even available until it is enabled on the ribbon.

All Office applications use the ribbon. One tab on the ribbon is the Developer tab, where you access the Visual Basic Editor and other developer tools.

Because Office does not display the Developer tab by default, you must enable it by using the following procedure:.

On the File tab, choose Options to open the Options dialog box. Under Choose commands from on the left side of the dialog box, select Popular Commands.

Under Customize the Ribbon on the right side of the dialog box, select Main Tabs in the drop down list box, and then select the Developer checkbox.

In Office , you displayed the Developer tab by choosing the Office button, choosing Options , and then selecting the Show Developer tab in Ribbon check box in the Popular category of the Options dialog box.

After you enable the Developer tab, it is easy to find the Visual Basic and Macros buttons. To protect Office users against viruses and dangerous macro code, you cannot save macro code in a standard Office document that uses a standard file extension.

Instead, you must save the code in a file with a special extension. For example you cannot save macros in a standard Word document with a. When you open a.

Examine the settings and options in the Trust Center on all Office applications. The default setting disables macro from running, but warns you that macros have been disabled and gives you the option to turn them back on for that document.

You can designate specific folders where macros can run by creating Trusted Locations, Trusted Documents, or Trusted Publishers.

The most portable option is to use Trusted Publishers, which works with digitally signed documents that you distribute.

For more information about the security settings in a particular Office application, open the Options dialog box, choose Trust Center , and then choose Trust Center Settings.

Some Office applications, like Outlook, save macros by default in a master template on your local computer.

Although that strategy reduces the local security issues on your own computer when you run your own macros, it requires a deployment strategy if you want to distribute your macro.

When you choose the Macro button on the Developer tab, it opens the Macros dialog box, which gives you access to VBA subroutines or macros that you can access from a particular document or application.

Another button on the Developer tab in Word and Excel is the Record Macro button, which automatically generates VBA code that can reproduce the actions that you perform in the application.

Record Macro is a terrific tool that you can use to learn more about VBA. Reading the generated code can give you insight into VBA and provide a stable bridge between your knowledge of Office as a user and your knowledge as a programmer.

The only caveat is that the generated code can be confusing because the Macro editor must make some assumptions about your intentions, and those assumptions are not necessarily accurate.

Open Excel to a new Workbook and choose the Developer tab in the ribbon. Choose Record Macro and accept all of the default settings in the Record Macro dialog box, including Macro1 as the name of the macro and This Workbook as the location.

Choose OK to begin recording the macro. Note how the button text changes to Stop Recording. Choose that button the instant you complete the actions that you want to record.

Choose cell B1 and type the programmer's classic first string: Hello World. Stop typing and look at the Stop Recording button; it is grayed out because Excel is waiting for you to finish typing the value in the cell.

Choose cell B2 to complete the action in cell B1, and then choose Stop Recording. Be aware of the similarities to the earlier code snippet that selected text in cell A1, and the differences.

In this code, cell B1 is selected, and then the string "Hello World" is applied to the cell that has been made active.

The quotes around the text specify a string value as opposed to a numeric value. Remember how you chose cell B2 to display the Stop Recording button again?

That action shows up as a line of code as well. The macro recorder records every keystroke. The lines of code that start with an apostrophe and colored green by the editor are comments that explain the code or remind you and other programmers the purpose of the code.

VBA ignores any line, or portion of a line, that begins with a single quote. Writing clear and appropriate comments in your code is an important topic, but that discussion is out of the scope of this article.

Subsequent references to this code in the article do not include those four comment lines. When the macro recorder generates the code, it uses a complex algorithm to determine the methods and the properties that you intended.

If you do not recognize a given property, there are many resources available to help you. For example, in the macro that you recorded, the macro recorder generated code that refers to the FormulaR1C1 property.

Not sure what that means? Be aware that Application object is implied in all VBA macros. The code that you recorded works with Application.

Select FormulaR1C1 in the recorded macro and press F1. The Help system runs a quick search, determines that the appropriate subjects are in the Excel Developer section of the Excel Help, and lists the FormulaR1C1 property.

You can choose the link to read more about the property, but before you do, be aware of the Excel Object Model Reference link near the bottom of the window.

Choose the link to view a long list of objects that Excel uses in its object model to describe the Worksheets and their components. Choose any one of those to see the properties and methods that apply to that particular object, along with cross references to different related options.

Many Help entries also have brief code examples that can help you. For example, you can follow the links in the Borders object to see how to set a border in VBA.

The Borders code looks different from the recorded macro. One thing that can be confusing with an object model is that there is more than one way to address any given object, cell A1 in this example.

Sometimes the best way to learn programming is to make minor changes to some working code and see what happens as a result.

Try it now. Notice the use of the XmlReader. Create method in above listing. You may be used to creating concrete implementations of an XmlReader, but if you try this technique, you should find it much more flexible because you can reuse the XmlReaderSettings objects in the creation of other instances of XmlReader.

The countries. The file name with full path is then passed into XmlReader. Create, along with the XmlReaderSettings instance. The read method continues to return true if the node was read successfully.

It will return false when no more nodes are left to read. XmlReader treats everything as a node including comments, attributes, elements and end elements.

That's where we are checking node type to be element. If not, XmlReader will return number of countries to be 12 including end elements because end element's local name is also Country.

XmlWriter works exactly like XmlReader except in reverse. XmlWriter is a abstract class that helps generate XML streams or files.

It is recommended in ASP. NET 2. The create method allows you to specify the features to support on the created XmlWriter using XmlWriterSettings.

This settings class has options for indentation, new lines, encoding and XML conformance level. Xml file using XmlWriter.

The XmlwriterSettings. Indent property includes indentation that makes the resulting XML document more readable.

ReadSubTree: This method reads the current node of an XmlReader and returns a new XmlReader that traverses the current node and all of its descendants.

XPathDocument is most efficient way to use XPath expressions over an in-memory data structure. XPathDocument allows you to move freely, forward and backward within the document.

MSComm Elemant. Setting Communication of Serial Port. Using Buffer for receive and sent data. Define MSComm Control properties to connect port.

We can using the MSComm properties allow the setting of communication parameters including port selection and port enabling functions.

Exemple If we want print data to port while we are typing data to keyborad ,we use event the KeyPress of Control TextBox.

Text End If TextShow. Text End Sub. Copy code in ListBox below. Using Even in OnComm procedure. Final Notes 1. Check your serial port programming manual for the correct number of characters to be recieved and add one for the carriage return.

The command sends both a carriage return and line feed thus two must be added to the number of characters expected.

For example, the "GO" command outputs to port A, the integer value position. If the position is a variable , a string to set the port to the value of this variable would look like; MSComm1.

You may be many question how to communicate with microcontroller ,So, we can use concept on above to apply in your project ,process for communicate is like my exemple programming but you will be know protocol of those device.

When the client start its get connect the server and send requests , and also receive the response from Server. Click the following link to see in detail of Client Socket Program.

Server Socket Program. Client Socket Program. Next step is to start Client Socket Program. Then you will get message in client screen Client Started , at the same time you check with server screen a message Accept connection from client.

If you want to test the communication , you click the button Click here to send data to Server in client window , then you can see changes in Server and Client screen messages.

Home C VB. In the above picture shows the communication interfaces. How to run this program? The Socket Programming has two sections.
