提问by kishan
I am new to VB Dot Net. I am using ComponentOne True OLE DbGrid in my form. Now I need to add Value Items to my column.So i tried this: TDBGrid1.Columns(14).ValueItems.Add(New TrueOleDBGrid80.ValueItem()) TDBGrid1.Columns(14).ValueItems(2).Value = 2 My code is compiling and running well. But when i try to run my exe on client machine it gives me Error: "Retrieving the COM class factory for component with CLSID failed due to the following error: 8007045a " for the above ValueItems.Add() line. Please, help me. Thanks
我是 VB 点网的新手。我在我的表单中使用 ComponentOne True OLE DbGrid。现在我需要将值项添加到我的列中。所以我尝试了这个： TDBGrid1.Columns(14).ValueItems.Add(New TrueOleDBGrid80.ValueItem()) TDBGrid1.Columns(14).ValueItems(2).Value = 2 My代码编译运行良好。但是，当我尝试在客户端计算机上运行我的 exe 时，它给了我错误：“由于以下错误，检索具有 CLSID 的组件的 COM 类工厂失败：8007045a”对于上述 ValueItems.Add() 行。请帮我。谢谢

The issue seems to be due to difference in the processor on which the application was created and is being run on. You might look for the respective dll in the following locations, use it in your project and see if it solves your issue: 64 bit machine : HKEY_CLASSES_ROOT\CLSID{###}\InprocServer32 32 bit machine : HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Classes\CLSID{###}\InprocServer32.
该问题似乎是由于创建和运行应用程序的处理器不同所致。您可能会在以下位置查找相应的 dll，在您的项目中使用它并查看它是否能解决您的问题：64 位机器：HKEY_CLASSES_ROOT\CLSID{###}\InprocServer32 32 位机器：HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Classes \CLSID{###}\InprocServer32。
