runtime error 53 - "file not found"

[Vikas K]

Hi, I'm using VC6.0 DLL with VB.NET. XYZClient.dll is in the same directory as the VB.NET exe is present. But, still I get this runtime error on some PCs.It works on couple of PC without any issues. I tried on Windows XP as well as 2K. Results are intermittent. Any idea? In VB, function is decalred as below: Declare Function XYZOpenConnection Lib "XYZClient.dll" (ByVal IPAddressOrMachineName As String, ByVal usernameOfXYZUserGroup As String, ByVal applicationData As Integer) As Short Thanks Vikas

you can use the dependency viewer to look at the files on which XYZClient.Dll is dependent on. I guess on some of the machines these files are missing.

Do you need the VC++ redistributable installed on those PCs?

Actually, I had compiled the VC++ DLL in debug mode and it was the issue. The moment I had release mode DLL. it worked fine. Thanks Vikas
