• Tryst Calling C++/CLI dll from C#

  I work on an app that controls a Canon camera in C#. Until now, I used a common C# wrapper for their SDK. They have a new SDK. So, I wrote a wrapper in C++/CLI. But, it stopped working, it gives an error : The specified module could not be found. (Exception from HRESULT: 0x8007007E). I found on my notebook that creating a vanilla C++/CLI dll with a simple method, and calling it from C#, compiles but gives this error. On my desktop, however, it works fine. So, I rebuilt the wrapper dll, and integrated it into my app. The same dll, with the same manifest file ( it's also got one embedded ), gives this error in my app, but runs in a very simple app ( which just calls the same methods ). I think the problem is WinSxS ( which has been an ...Show All

• reddfan How to create threadsafe application in VC++?Getting error "SystemExecutionEngine".

  I am developing an application in VC++.NET using Visual Studio .NET IDE. Application has a UI and worker thread. I am also using QF Framework. When application starts, it loads UI and starts worker thread. Worker thread deals with RS232 port. It sends/receives data over serial port. PC application generates requests at certain interval and writes it to serial port. On receiving response, worker thread updates it to UI control(RichTextBox). Application runs fine for 4-7 iterations and then fails with SystemExecutionEngine error .It runs for longer hours on certain windows machine and fails less than 4-5 minutes on some machine. When it crashes, it shows up in disassembly code at " NTWaitForSingleObj ...Show All

• Ben Corneau PSDK/calc-sample, please.

  Below is error when I try to build sample project: Calculator. I have VC++ express edition and sample is for that version of C++. I also have PSDK which I wanted to integrate with VC++ express edition by following instructions; but wanted to be sure VC++ express edition is working (which it is not) by using simple sample projects. Thank you very much for any assistance to get this sample project to run/compile. I plan to use VC++ instead of fortran for my research so I and other students/scientists may have a graphical user interface and ease of entering code. Assembly language was no fun but I got thru that. I would be grateful if anyone could point me to sample code to use in VC++ express edition (with PSDK integrated ...Show All

• Neotech internal compiler error (compiler file 'f:\vs70builds\6030\vc\Compiler\Utc\src\P2\p2symtab.c', line 4537)

  I'm getting the following error when trying to compile a C++ file in VS 2003 with SP1: fatal error C1001: INTERNAL COMPILER ERROR (compiler file 'f:\vs70builds\6030\vc\Compiler\Utc\src\P2\p2symtab.c', line 4537) It happens on the following line in my code: const char* p = "SomeText"; If I were to change this line to something like const char* p = "SomeOtherText"; then it would compile just fine. I've trying doing a complete rebuild, but the problem is still there. Any ideas what is going wrong That's pretty weird.  Something like this must be very rare, and together with the fact this is VS 2003, you'll probably just have to change your code in whichev ...Show All

• billqu textBox - 2 questions

  Hi all. I have a textBox controler in my win app that i write in c++. I insert data into the textBox in runtime. 2 Questions: 1) Is it possible to insert the data in LIFO that means that if i insert line "bla bla bla" then new line and then "yada yada yada" it will appear as yada yada yada bla bla bla Is it possible without clearing the box each time, writing new line and then filling with old data. (I have a lot of info and after a while the screen updates slow) 2) If the first question is answered and the data is inserted in LIFO, is it possible to show only the last X lines As i mentioned i have a lot of data comming in but only the last data is the relevant to see...
