• Visual C++ No memory leak detection in native lib when called via managed wrapper (c++/cli)?!

  Hi, I'm testing around with a native library (c++) and it's managed wrapper (c++/cli). The wrapper is called by a little c#-program. In the native library I inserted some pieces of code for memory leak detection like: #define _CRTDBG_MAP_ALLOC #include <stdlib.h> #include <crtdbg.h> and _CrtDumpMemoryLeaks(); It works "fine" (it detects memory leaks) when I call it from a native exe-project like: int _tmain(int argc, _TCHAR* argv[]) { VConcreteClass1* pObj = new VConcreteClass1(); return 0; } Then the output-window in my vs2005 shows: Detected memory leaks! Dumping objects -> .... But when I create an object of the VConcreteClass1 via VConcreteClass1* pObj = new VConcreteClass1(); and without delete pObj; then ...Show All

• .NET Development Complex Event Processing / Event Stream Processing

  Hi, I was wondering if anyone here has some experience building a CEP/ESP engine on top of the .NET Framework If so, could you give some starters how this scenario was approached Thanks! Tom Hi Salvador, thanks a lot for your reply! I'm having a two-fold use case that I want to target here within a financial trading solution domain. One is as you mentioned server side event processing, analyzing order flow and financial market data. However #2 is that the same engine should be applied to client front-ends. Goal is to provide a visual IDE for clients, so they can quickly build a rule set to analyze the subset of data they are receiving and trigger certain actions based on them. This cuts short the usage of ...Show All

• .NET Development manual IL code fails verification with "unable to resolve token"

  Hi, I'm trying to write a (naive concept test) script that adds a prologue & epilogue to methods. It modifies the output of ildasm on an assembly to create a new IL file which I in turn compile with ilasm. It works by adding the following lines to the begining of every method: call class [Reflex]Reflex.ReflexWriter [Reflex]Reflex.ReflexWriter::get_Instance() callvirt instance void [Reflex]Reflex.ReflexWriter::Enter() It works on very simple assemblies I compiled with C#. To challenge my naive idea, I tried running it on the fxcop executable. The executable compiled but peverify fails with many similar errors, I copied the first one here: [IL]: Error: [D:\Program Files\Microsoft FxCop 1.35\FxCopy_trac ...Show All

• Visual Studio Team System n mi Upgrade database to specified version in automated build task

  We are using team build to run a nightly build and deployment to our test environment. We are thinking about to create a DBScripter.exe app to upgrade our Oracle DB to the specified version. It will look for change scripts and handle the upgrade of the database to a specified version. What can be a good approach to integrate this in the build process I was thinking about calling this at the BeforeCompile Event and the Exec command. But if the return code is less than zero from DBScripter.exe I want to cancel the build. How can I check for the return code and cancel the build if there is any error I would also thinking about using the assembly info task to apply a custom build number to the assembly files.

• Software Development for Windows Vista Drivers signing question.

  Hi all! My product installs a boot-start filter-driver, but uses co-installer for its setup. I have successfully signed this driver using MS recommendations, but I have a number of questions and I would be very happy if someone could help me clarify them: 1. For LOGO certification - is it obligatory to install filter-driver through .inf file or I can use co-installer 2. Shall I generate .inf and .cat files if I use 'co-installer' way 3. MS docs say that .cat files must be signed with a cross-certificate. But what about .sys-files inside the driver package What certificate should I use - from Verisign or the cross-certificate 4. In case of '.inf-file' installation scheme, are the sign rules similar for device drivers and for filter-drivers ...Show All

• SQL Server Trying to connect to SharePoint database

  I am having trouble connecting to the SharePoint database on my web server. Our company intranet is accessed by http://webservername/ and the SharePoint site is accessed by http://webservername:2020/ (I wanted to put it on a different port to not interfere with our old intranet). Anyway, I need to connect to the DOCS table on the content database, but I can't seem to connect with SQL Server 2005.

• Smart Device Development Heyelp! Using SendKeys in Visual Studio 2005

  Ok, I've only been using VS for about a month now, writing a little form/program to run on a PDA. All working fine, but it was suggested the PDA 'ok' key (return key basically) should be recognised and move the cursor from one prompt to the next. All sounds simple enough................... Well, I can trap the ok/return in the KeyPress event, but I then want to input a 'Tab' so that you move to the next prompt. So, I thought use SendKeys. But it doesn't appear to be available in System.Windows.Forms Is there something simple I am not doing We are using Visual Studio 2005 Standard Edition. When I look through the help system, SendKeys is included, but for some reason it is not currently available within the environment that is set up ...Show All

• Visual C++ Return value incorrect

  Hi, I've got a very weird thing in my program, const bool getRunning() const { Lock(); bool t = m_bRunning; Unlock(); return t;} Where m_bRunning == true; it returns false. ( lock and unlock handles the thread safety ) after the Unlock(), t contains true. but the return value is always false. even weirder, with code optimalisation on, the function isnt even reachable. it just skips it. //DEBUG 0041B5FE call Gameye::CApplicationInfo::getRunning (411677h) 0041B603 movzx ecx,al 0041B606 cmp ecx,1 ECX contains 205 after this.
