How to Add Windows Forms in Visual Basic 6.0 by WinForms GridControl?
To add our WinForms GridControl in Visual Basic 6.0, we should follow the steps below.
Step 1: Create a new WF library project.
Step 2: Add form and necessary controls
to the project.
Step 3: Include below class libraries
for InterOp functions.
Adding InterOP function
using System.Runtime.InteropServices;
using System.Text;
using System.Reflection;
using Microsoft.Win32;Step 4: Need to register Com objects, code snippet below in the class file for com registration.
Com file
[ComRegisterFunction()]
public static void RegisterClass(string key)
{
StringBuilder sb = new StringBuilder(key);
sb.Replace(@"HKEY_CLASSES_ROOT\", "");
RegistryKey k = Registry.ClassesRoot.OpenSubKey(sb.ToString(), true);
RegistryKey ctrl = k.CreateSubKey("Control");
ctrl.Close();
RegistryKey inprocServer32 = k.OpenSubKey("InprocServer32", true);
inprocServer32.SetValue("CodeBase", Assembly.GetExecutingAssembly().CodeBase);
inprocServer32.Close();
k.Close();
}
[ComUnregisterFunction()]
public static void UnregisterClass(string key)
{
StringBuilder sb = new StringBuilder(key);
sb.Replace(@"HKEY_CLASSES_ROOT\", "");
RegistryKey k = Registry.ClassesRoot.OpenSubKey(sb.ToString(), true);
k.DeleteSubKey("Control", false);
RegistryKey inprocServer32 = k.OpenSubKey("InprocServer32", true);
k.DeleteSubKey("CodeBase", false);
k.Close();
}Step 5: Need to check COM object visibility in Properties -> Application -> Assembly Information -> Check Make assembly COM – visible.
Step 6: Need to check the register for COM interop via Properties -> Build -> Register for COM interop.
Step 7: Rebuild the application and generate the project assembly.
Step 8: Open Visual Studio Command Prompt as administrator. And execute the command below.
Regasm “Assembly file path” for example [“C:/GaugeWF.dll”]
regasm “Assembly file path” /regfile:GaugeWF.reg
regasm “Assembly file path” /tlb: GaugeWF.tlb
regasm /codebase “Assembly file path”By following the above steps generated assembly will be registered in the local machine, and so it will be exposed asan ActiveX control. And it can be tested by opening it in the VS ActiveX control test container.
Step 9: For testing functionality, open the Active-X test container in the location below.
C:\Program Files (x86) \Microsoft Visual Studio 8\Common7\Tools\tstcon32.exe
Step 10: Select Edit -> Add New Control -> above control will be available in this location, and by double clicking on it, that will be integrated in the VBA container.
