Using Adobe Acrobat 7.0 Browser Control Type Library 1.0 in VB.NET Applications



Hi. Can I use acrobat professional 7 to combine multiple documents from an ASP.net app? I added the COM object Adobe Acrobat 7 type library to my project. I don't know if this is the way and I want to know how can I use acrobat functionalities from my asp.net app.




adobe acrobat 7.0 browser control type library 1.0 vb net




If you have Acrobat Professional 7 installed on the server, then your ASP.Net web application can utilize the type library to communicate with the Adobe app. However, it is doubtful whether the license of Acrobat Professional 7 allows for server side usage involving document generation.


Well a picture box is meant to hold graphics while the adobe acrobat 7.0 browser control type library 1.0 will allow you display pdf files... So are you wanting to put this control into a picture box, or are you wanting to use one of those print to Tiff drivers to print the adobe pdf via the shellexecute API with the "print" verb and then use WIA 2.0 to load and display the output in a picture box???


Keysight Secure Instrument Communication provides a secure way to control instruments using HiSLIP protocol revision 2.0 (r2). HiSLIP r2 enables secure connections, which are achieved using the Transport Layer Security (TLS) for encryption and decryption. HiSLIP r2 also enables authentication: the server (instrument) authenticates its identity by sending an X.509 certificate to the client (VISA library) when the TLS connection is established. The client authenticates to the server using a server-supported SASL (Simple Authentication and Security Layer) mechanism.


In our example app, those are items holding JPeg-image filenames of a folder ondisk. On the UI-side you have a user control which represents the template foreach element of the data source. At runtime, for each element in the data sourceone tile based on this user control template gets created. Each item of the datasource is then data-bound to the instance of that user control, and the usercontrol is responsible for rendering the content. To this end, ourTileRepeater control has an ItemTemplate property. This property determines,which type of an element of the data source results in what user controltemplate type in the UI. And to make this approach even more flexible,TileRepeater also has a SeparatorTemplate property: It determines another typefor the items, which would serve as a visible separator at runtime.


Here is what happens behind the scenes at design-time when the user sets thevalues for ItemTemplate or SeparatorTemplate. When they determine which ofthe element types in the data source list should lead to what user control type(derived from TileRepeaterTemplate) for the actual rendering container atruntime, this happens behind the scenes.


If you however just use the editors (which again need to be provided by theclient process), a server-only control designer suffices. In that case though,you need to state the types in the required attributes as strings, and cannotuse typeof (in C#) or GetType (in VB). It would look something like this:


CustomControlLibrary.Protocol: This project contains all the classeswhich are necessary for the communication between the client and the serverprocess via JSON-RPC. The Designer SDK providesa series of base classes which are optimized for transferringWinForms-typical data types between the client- and the server-process. Atypical protocol library for a control designer builds on those classes.


The Property Browser now calls the EditValue method of the Type Editor andpasses the value of the property to set. But, again, the value is not theactual value of the property. Instead, it is the Object Proxy, which points tothe instance of the property type in the server process. This alsomeans the processing of the value must happen in the server-process. To thisend, the two ViewModel types to control the edit procedure need now to beused: one on the client side (CustomTypeEditorVMClient), and one on theserver side (CustomTypeEditorVM). The template creates both classes for you,along with the infrastructure methods to set them up.


Creating a DLL in C# or VB.Net is not that hard as long as you have object oriented programming experience or knowledge.After creating the DLL, I tried to reference it from Access VBA editor but kept getting the message"Can't add a reference to the specified file.". After some research on this issue, I learned some new tricks about (1) how to correctly create a DLL for Access or Excel (or any Microsoft Office applications or VB6 applications), (2) how to correctly register a C# or VB.Net DLL, and (3) how to correctly reference the DLL within Access VBA or Excel VBA.In this article, I'm going to show you how to correctly create a C# or VB.Net DLL in Visual Studio and use it inside MS Access, Excel VBA, or VB6 applications. Hope the tips can save you a couple of hours or days of headaches.1. Create a new C# (or VB.Net) project and select Class Library as the template type.Save the project (and solution) as SimpleCalc.Below I created a simple calculation class for testing. This class has two variable members and one Add() method.The method adds two integer numbers and returns the result.using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace SimpleCalc public class Calc private int numberOne = 0; private int numberTwo = 0; public void SetNumberOne(int number) numberOne = number; public void SetNumberTwo(int number) numberTwo = number; // Add two integers public int Add() return numberOne + numberTwo; 2. Configure project properties to make it COM visible.Open project properties dialogue window. Go to menu Project -> SimpleCalc Properties.When the project properties window is opened, click Application tab, and then click Assembly Information button.On the Assembly Information window, check Make assembly COM-Visible.Applications created in VB or VBA are COM-based applications. So the class library youcreated in C# or VB.Net must be created as a COM visible assembly. This allows COM-based applications to call the class library's member variables and methods.3. Register for COM Interop.In addition to making the DLL COM-visible, we also need to register the assembly as a COM component in the Windows registry. There are a few ways to do it based on your circumstances.For a development machine, we can check "Register for COM Interop" setting in Visual Studio. On the project properties window, click Build tab. Then check Register for COM Interop (Based on your version of Visual Studio, it could be on a different tab). This makes Visual Studio do two things automatically when the project is compiled. First, it will generate a .tlb type library file. Second, it will register class information for the COM component in Windows registry.The Register for COM interop property specifies whether your application will expose a COM object to client applicationsso that they can interact with your COM object transparently. Here is what is registered in Windows registry for the compiled assembly so that COM clients can use the .NET class transparently.Note that the path to the DLL is stored in CodeBase entry.To register the assembly on other computers such as production machines, you can register the assembly byusing RegAsm.exe. See this article for details.4. Compile the project.Build the solution. Then go to bin folder. Depends on whether your build is a Debug or Release build,you can find the DLL and .tlb type library file in either Debug or Release folder under the bin directory.In our case, it's D:\CSharp\SimpleCalc\SimpleCalc\bin\Release5. Copy the type library file to Windows system folder.Windows system folder C:\WINNT\system32 is the default location for DLLs and type libraries so we copy type library SimpleCalc.tlb to it.6. Reference the type library from Access VBA editor.First, create a new Access database and open Visual Basic code editor. In the menu cross the top, clickTools -> References...When the References window is opened, click the button Browse.Then browse to folder C:\WINNT\system32 and select file SimpleCalc.tlb and click Open.After done, SimpleCalc will appear in your reference list and you need to move down in the list to find and check it. Then click OKto close the Reference window.You may remember in the registry screenshot above, there is a DLL path value in CodeBase entry. VBA will use this registry informationto find which DLL to call. In our case, it's D:\CSharp\SimpleCalc\SimpleCalc\bin\Release\SimpleCalc.dll7. Use the DLL in your VBA code.To use the variables and methods in the C# DLL, we need to call the DLL inside VBA. Add a button to the Access form and then add a click event to it. In the click event we call a function called test() which is created within a VBA module. Below is a sample VBA to call SimpleCalc.dll. test() function invokes the .Net DLL by creating a new object from Calc class and then call its methods.Public Function test() Dim lngResult As Long Dim objCalc As SimpleCalc.Calc Set objCalc = New SimpleCalc.Calc objCalc.SetNumberOne (3) objCalc.SetNumberTwo (6) lngResult = objCalc.Add() End FunctionIf we debug and step through the test function, we will see the result is 9 as it's calculated inside the C# DLL and returned to VBA.You can see the result value either in Immediate window or by moving mouse over the lngResult variable.In this article, we have gone through the steps to create a .Net C# DLL and then use it inside Access VBA. It brings the power of .Netinto Microsoft Office applications. The limitation in this article is that Visual Studio registered our DLL and type library automatically for our development machine only. We haven't covered how to deploy the DLL to a production machine. In this case, check out this article about how to use Regasm.exe (Assembly Registration Tool) to register DLL on a target machine or production computer. Note that you can also create a setup package for your application and add regasm.exe as a custom command to the installer package.Happy Coding!Copyright GeeksEngine.comRelated Articles:1.How to correctly reference and call a DLL2.How to register a C# or VB.Net DLLOther Recent Articles from the MS Access category:1.Solved: MS Access error "The text is too long to be edited"2.Create MS Access Combo Box essential properties by VBA code3.Create MS Access Combo Box essential properties manually4.How to do text search in MS Access programmatically5.Solved - the size of the Access query result is larger than the maximum size of a database (2 GB)6.How to easily get a list of field names in MS Access7.How to count distinct records in MS Access8.How to do transaction based processing in MS Access9.How to open a document (local/network file or web page) from MS Access10.How to use ADOX to create unique composite index - the VBA approach11.How to do cross-table update queries in MS Access - the right way12.Three efficient ways to get the number of records by using VBA13.How to create a composite unique index (not as a primary key) in MS Access14.Use VBA to get the correct number of records in a Recordset object15.Disable Access Prompt when a record is changed, table deleted, or action queries run16.How to hide and unhide a MS Access object17.How to return multiple values from a VBA function (Part 3)18.How to return multiple values from a VBA function (Part 2)19.How to return multiple values from a VBA function (Part 1)20.Three ways to programmatically duplicate a table in MS Access by VBA21.How to correctly reference and call a DLL22.How to register a C# or VB.Net DLL23.Email address validation by Regular Expressions using VBA24.Fix MS Access error: Query must have at least one destination field25.How to unselect radio buttons in MS Access after it has been selected26.How to Change Query Timeout Value for MS Access SQL Queries27.What is Northwind Traders databaseCopyright 2023 GeeksEngine.com.
