When “Enable native code debugging” is enabled, output from consoles crated with AllocConsole is redirected to the debug output window instead. The reason this only happens in x86 and not AnyCPU is because you can only debug native code in an x86 application. Note that this behavior only occurs with consoles created with AllocConsole. A … Read more
I’d do it with a BSTR since it means you don’t have to call into native twice per string, once to get the length and then once to get the contents. With a BSTR the marshaller will take care of deallocating the BSTR with the right memory manager so you can safely pass it out … Read more
Based on your input I have done the following code: public class FileUnblocker { [DllImport(“kernel32”, CharSet = CharSet.Unicode, SetLastError = true)] [return: MarshalAs(UnmanagedType.Bool)] private static extern bool DeleteFile(string name); public bool Unblock(string fileName) { return DeleteFile(fileName + “:Zone.Identifier”); } } Thanks to Stuart Dunkeld, Alex K(+1) and Sven to show me the direction. UPDATE I … Read more
Well according to the MSDN DWORD is an unsigned integer with a range of 0 to 4294967295. So ideally you should replace it with uint rather than int. However, as you have spotted uint is non-CLS compliant so if your method is publicly visible you should use int and do the conversion. The corollary to … Read more
can it be that you are looking for System.Diagnostics.SymbolStore.ISymbolScope. Have a look at the class SymbolAccess, you can use it to gain access to ISymbolScope.GetLocals() that returns ISymbolVariable[] and GetChildren() again returning in this time an array called ISymbolVariable[] Now another interesting set of reference code samples is the Debugger extension lets you “snif” the … Read more
If the library is already registered, you can perform the following steps to have Visual Studio generate an interop assembly for you: Open to your Visual Studio project. Right click on ‘References’ (right under the project in your Solution Explorer) and select ‘Add Reference’. Select the COM tab. (If you don’t see this, you have … Read more
In the case where I am working with an existing C library, I prefer PInvoke. PInvoke, while a bit tedious and troublesome at times, is a fairly well understood technology that has an ever growing set of tools and internet documentation available. Generally speaking, whatever problem you run into, there is already a sample available … Read more
As mentioned in Dane Rose’s comment, you can either use __stdcall on your C++ function or declare CallingConvention = CallingConvention.Cdecl on your DllImport.
What you can do is Create a hidden window in your Console application which is used to handle the hotkey notification and raise an event. The code HERE demonstrates the principal. HERE is an article on handling messages in a Console application, using this you should be able to enhance HotKeyManager to run in a … Read more
This can be little bit late, but still. I tried all of the examples here, but no one was working for me in 32 and 64 bit mode simultaneously. Finally, I was required to examine all the signatures myself and create corresponding PInvoke routines. I think, somebody else could find this helpful. Disclaimer: the solution … Read more
