Hi all, I have to make a call to an ActiveX component from C#. The ActiveX call expects a VARIANT *. I keep getting an exception (COMException) "type Mismatch" on making the call. The call I made was { Object Obj = new Object(); ActiveXCall(ref Obj); // Gives "Type mismatch" at run t...more >>

I'm writing an app that does real time data acquisition, and needs to respond to DMA-complete events that get signalled every 10mS approximately. Currently I have some native C++ code that works very nicely, with a dedicated 'daemon' thread that waits on a Win32 Event and kicks off the next DMA ...more >>

Dear all: I´m a bit confused after reading about exception handling in the ECMA standard. In Partition I, section 12.4.2, Exception handling, it says: "A user-filtered handler that runs a user-specified set of CIL instructions to determine whether the exception should be ignored (i.e. ex...more >>

hi, I am a bit confused about .NET framework. Does the functions avaiable in ..NET call the underlying Win 32 APIs or the fuctions are implemented in the framework itself ? Also there are some different APIs available for win98 and win2000. So if ..NET calls the OS APIs then does it detect ...more >>

Hi all, first of all, I'm a .NET newbie, and while I have done some basic research and browsing, chances are that my question is trivial and I should simply RTFM; I apologize. Also, if this is not the right newsgroup, let me know. We want to add a .NET wrapper on an existing C++ applicatio...more >>

Hi all. What's the difference, from the OS point of view, between Monitors and Mutexes? I'm almost sure that the Mutex object is a wrapper to the native win32 mutex (if I create a named managed Mutex, I can see it with winobj) Is there a relationship between the win32 native "CriticalSect...more >>

In very rare cases, we are getting an OutOfMemoryException coming out of String.PadRight(int, char). At the time, there is certainly plenty of memory free as far as I can see. The application is not using excessive memory (using around 80MB with around 300MB free and plenty of swap space). I h...more >>

Maybe someone knows how to solve this one. My context is the following: a VB.NET WinForms app gives the following error message when launched in the Internet Zone.

Hi. What is the difference between these two approaches? My thought is that CCW automatically loads the runtime, with default settings, while with CLR hosting you have control over each step of the runtime loading (type of GC and so on). Am I right? Have a nice day GV...more >>

I was recently set to release an app that used very common single instance code and hit the oddest issue. After many hours of full build tests I believe that it is duplicatable. Environment: ..Net 1.1 (v1.1.4322) Windows 2000Pro HyperThreading machine Issue: Install 2kPro on the HT...more >>
