try { // call to Com Method } catch (COMException e) { if (e.ErrorCode == 0x80040154) // REGDB_E_CLASSNOTREG. { // handle this error. } } I would like to check if com exception is thrown due to REGDB_E_CLASSNOTREG then handle it. I tried with the code above but it gives warning: Comparison to integral constant is useless; the constant is outside the range of type 'int' I believe this error is due to 0x80040154 is not in Int32 range. Can you suggest any possible solution? or Is there any other way to check this? Use the unchecked keyword: catch (COMException ex) { if (ex.ErrorCode == unchecked(

Here's my problem: I have to call a web service with a secure header from a classic ASP page that returns a complex data type. For various reasons concerning a 3rd party tool it has to be classic ASP. We decided that I should create an external dll to do this - which I did (in c#) so it returns a dataset (Something ASP can understand). However now I need to expose that function to the ASP page. Because this is classic ASP I think the only straightforward way to do this is to expose this class library as a COM object. I need to know the down and dirty easiest way to accomplish this task. What

I'm thinking of rewriting a brand new VB.NET application in VB 6. The application runs under terminal services and makes heavy use of COM. For some reason, there is random weirdness with the application - Random Access Violation errors (WinDbg exception analysis points into dll's like comdlg32.dll, mscorwks) Random Buffer Overflow errors (same) Random errors in general - for example this line in Form.Load sometimes throws - Me.Icon = Resources.MyIcon I have followed all possible advice concerning resources, garbage collection, disposal patterns, etc... It just doesn't seem to do any good. I'm

I think this article has the same problem with me. However, there's no workable solution for my case. I'm using Windows Media Player ActiveX in my program. For some reason, I don't want to add a reference of it and convert to AxHost automatically by IDE. I create the instance by Activator and ProgID protected const string WMP_PROG_ID = "WMPlayer.OCX.7"; private dynamic _wmp; protected virtual bool init(){ try{ _wmp = Activator.CreateInstance(Type.GetTypeFromProgID(WMP_PROG_ID)); } catch{ return false; } return true; } I was tried to do this by Reflection , but I found that dynamic is suitable

So this is a more refined version of a question I asked earlier. I have been trying to sort this out for quite a while. I found a site that makes sense, but I can't implement it for some reason. I just want to be able to copy information from excel (tables, charts, ranges, etc) into the body of an outlook email. From here: http://pastebin.com/4VWmcrx6 It suggests: Using VB.NET to copy Excel Range (a table) to body of Outlook email Sub CopyFromExcelIntoEMail() Dim Doc As Word.Document Dim wdRn As Word.Range Dim Xl As Excel.Application Dim Ws As Excel.Worksheet Dim xlRn As Excel.Range Set Doc =
