  • Compiler #defines for g++ and cl

    - by DHamrick
    I am writing a program that is cross platform. There are a few spots where I have to specify an operating system dependent call. #ifdef WINDOWS ..do windows only stuff #endif #ifdef LINUX ..do linux only stuff #endif Are there any preprocesser directives that get defined by the compiler so I don't have to explicitly define them when I use the command line compiler. ie. cl -DWINDOWS program.cpp or g++ -DLINUX program.cpp I realize I could easily write a makefile or have a shell/batch script that will do this automatically. But I would prefer to use the same ones as the compiler (if they exist) by default.

  • Resharper 5 - enable/disable on the fly

    - by Cristi Diaconescu
    I want to disable ReSharper 5 when debugging - it slows things down more than I'm willing to take. Is there an automatic way to do this? The next best thing would be a toolbar button to manually enable/disable it. On the Tools - Options - ReSharper page there's a comment that the VS command Resharper_ToggleSuspended would do just this. The problem is, I can't find the command when I right-click a toolbar - Customize... - 'Commands' tab - Choose 'Resharper' category. Am I missing something?

  • Adding dlls in VS 2008

    - by Bart
    Hello, i would like to add some external .dll libraries e.g. glut32.dll (but it's only example) in vs 2008 using C#. Can you please tell me what should i do step by step? i am a little bit confused cause i found a lot of solutions to add dll files but they significantly differ.. some of them add dll's only using code, some using properties in vs, add references and in other tutorials there is about registering dlls in system. But how to put it all together? Regards!

  • Cannot create instance of 'Ribbon'

    - by user354433
    I'm having trouble using the Ribbon control from the Office 2007 RibbonControlsLibrary.dll. It works for most people but not for me. The fault I get is: Cannot create instance of 'Ribbon' defined in assembly 'RibbonControlsLibrary, Version=3.5.31016.1, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. Exception has been thrown by the target of an invocation The problem is probably not with the code since it works for other people. Its the Ribbon class thats causing the problem. If I remove any references to the Ribbon class but keep the references to RibbonWindow I don't get any exceptions. Any help appreciated

  • Sharing some info with all DLLs pulled into a process

    - by JBRWilkinson
    Hi all, We've got an Enterprise system which has many processes (EXEs, services, DCOM servers, COM+ apps, ISAPI, MMC snapins) all of which make use of many COM components. We've recently seen failures in some of the customer deployments, but are finding it hard to troubleshoot the cause. In order to track down the problem, we've augmented the entire source with logging statements where errors occur. In order to identify which logs came from what processes, the C++ logging code (compiled into all components) uses the EXE name to name the log. This is good for some cases, but not all - COM+ apps, ISAPI and MMC snapins all have system EXE names and the logs end up interleaved. I saw this post about shared data sections which might help, but what I don't understand is who decides what goes in the shared section. Is there any way I can guarantee that a particular piece of code writes into the shared section before anyone else reads it? Or is there a better solution to this problem?

  • How do virtual destructors work?

    - by Prabhu
    Few hours back I was fiddling with a Memory Leak issue and it turned out that I really got some basic stuff about virtual destructors wrong! Let me put explain my class design. class Base { virtual push_elements() {} }; class Derived:public Base { vector<int> x; public: void push_elements(){ for(int i=0;i <5;i++) x.push_back(i); } }; void main() { Base* b = new Derived(); b->push_elements(); delete b; } The bounds checker tool reported a memory leak in the derived class vector. And I figured out that the destructor is not virtual and the derived class destructor is not called. And it surprisingly got fixed when I made the destructor virtual. Isn't the vector deallocated automatically even if the derived class destructor is not called? Is that a quirk in BoundsChecker tool or is my understanding of virtual destructor wrong?

  • "Error opening associated documents" message when loading VS

    - by kumar
    When loading up a solution in VS2008 I get this message: An error was encountered while opening associated documents the last time this solution was loaded. Document load is being skipped during this solution load in order to avoid that error. It shut down immediately the first time I opened it. The next time I opened it, VS popped up a message box but did not shut down at first; however, it did shut down when I clicked a usercontrol or ASPX page. How can I find which document is causing the problem? Thanks...

  • Cannot work for 2nd iteration because of writing delay.

    - by karikari
    My code's IF-THEN does not work for 2nd iteration. This is due to, the jar processing take some time to write it result inside the output.txt. Since the writing is a bit late, my code's 2nd iteration will always read the previous written value inside the output.txt in order to pass it to the IF-THEN. For example, in 1st iteration: output.txt -- 0.9888 twrite.txt -- msg: ok 2nd iteration: output.txt -- 0.5555 twrite.txt -- msg: ok //the IF-THEN still gives this result which is based on previous iteration. it should be msg: not ok . since it is < 0.7 I need help, how to solve this 'delay' problem? HRESULT CButtonDemoBHO::onDocumentComplete(IDispatch *pDisp, VARIANT *vUrl){ ATLTRACE("CButtonDemoBHO::onDocumentComplete %S\n", vUrl->bstrVal); WinHttpClient client(vUrl->bstrVal); client.SendHttpRequest(); wstring httpResponseHeader = client.GetHttpResponseHeader(); wstring httpResponse = client.GetHttpResponse(); writeToLog(httpResponse.c_str()); if (isMainFrame(pDisp)){ m_normalPageLoad=false; FILE *child = _popen("javaw -jar c:\\simmetrics.jar c:\\chtml.txt c:\\thtml.txt > c:\\output.txt", "r"); fclose(child); char readnumber[10]; float f = 0; FILE *file11 = fopen("c:\\output.txt","r"); char* p = fgets(readnumber,10,file11); std::istringstream iss(p); iss >> f; if (f > 0.7) { wfstream file12 ("c:\\twrite.txt", ios_base::out); file12 << "Msg: ok"; file12.close(); } else { wfstream file12 ("c:\\twrite.txt", ios_base::out); file12 << "Msg: not ok"; file12.close(); } iss.clear(); fclose(file11); return S_OK; } return S_OK; }

  • Debugged Program Window Won't Close

    - by Marc Bernier
    Hi, I'm using VS 2008 on a 64-bit XP machine. I'm debugging a 32-bit C++ DLL via a console program. The DLL and EXE projects are contained in the same SLN so that I can modify the DLL as I test. What happens is that every once in a while I kill the program with Debug | Stop Debugging (Shift-F5). VS stops the program, but the console window stays open! If I'm sitting at a breakpoint and hit Shift-F5, it will terminate properly, but if the program is running full-tilt when I stop it, I often see this instead. The big problem is that I can't close these zombie windows. Using End Task in Task Manager does nothing (no message, no nothing). When I shut down the machine, it is unable to due to the orphans and I have to resort to actually turning off the power. I think this is connected to having the DLL and EXE project in the same SLN, as for months I worked on this project in 2 VS instances, one for the DLL and the other for the EXE. I would continually jump back and forth between the windows as I worked. This problem never happened until I put the two projects into a single SLN. The single SLN works a lot better, but this anomaly is very irritating. Any ideas anyone? UPDATE After a bit of searching (here), I found that it appears to have to do with one of the updates from last Tuesday (KB977165 or KB978037). Thank you Microsoft for your excellent pre-release testing.

  • programming question about numbers

    - by Syom
    it's a task, on which i think during whole day. i have four integer numbers a, b, c, d, and ineger x[1,40]. i must write a program, which can find the values of {a,b,c,d}, for which one of following equations is true for any (x<=40, x=1) x=a or x=b or x=a+b or x=a+b+c+d or x+a=c+d or x+a+b=c+d or ... x+a+b+c=d or ... it is very difficult to explain what i want to say. maybe the example will be helpful. example: if x=17, by {a=1,b=2,c=5,d=15} i can write x+a+b=c+d whole question is to present any x[1,40] by {a,b,c,d}. hope that you understand what i want to say, and thanks in advance

  • Signing 3rd Party Assemblies leads to them turnign invisible!

    - by Andrew
    Hi All, I followed OJ's instructions here This allowed me to successfully breakdown, then rebuild and sign some 3rd party DLLs. Here's what I did: Dissassembled Old.dll Rebuild and signed as New.dll (using the same *.snk that my VS2005 proj is signed with) Removed all references in my proj to Old.dll and added references to New.dll Replaced 'Imports Old.dll' with 'Imports New.dll' this final step fails. VS2005 won't recognise my New.dll Any clues?

  • Should I use a global var or call the function every time? C++

    - by extintor
    Im using: bool GetOS(LPTSTR pszOS) { OSVERSIONINFOEX osve; BOOL bOsVersionInfoEx; ZeroMemory(&osve, sizeof(OSVERSIONINFOEX)); osve.dwOSVersionInfoSize = sizeof(OSVERSIONINFOEX); if( !(bOsVersionInfoEx = GetVersionEx ((OSVERSIONINFO *) &osve)) ) return false; TCHAR buf[80]; StringCchPrintf( buf, 80, TEXT("%u.%u.%u.%u"), osve.dwPlatformId, osve.dwMajorVersion, osve.dwMinorVersion, osve.dwBuildNumber); StringCchCat(pszOS, BUFSIZE, buf); return true; } to get the windows version, and I am planning to use pszOS every a few minutes, Should I use pszOS as a global var or call GetOS() every time? What's the best option from a performance point of view.

  • Is MS Reporting Services suitable for stand-alone reports?

    - by JMarsch
    Hello all: I work for a ISV. Our product can use both SQL Server and Oracle as its back-end server. It includes a number of reports (currently in Crystal). We are investigating moving to Micrsoft Reporting Services, but I'm beginning to think that it's a bad idea. We want for our reports to look and feel as though they are a part of our application, and we will not require SQL Server (the customer can choose Oracle). Although I see the reporting services supports a stand-alone mode (RDLC), the boundry between what requires SQL server and what doesn't looks extremely ambiguous. (example, the stand-alone report builder appears to require SQL Server, most of the documentation appears to be part of SQL Server's documentation) It looks to me like if I want to keep my application DB-agnostic, I had better steer clear of Reporting Services. Have I missed the boat here?

  • Avoiding 'Buffer Overrun' C6386 warning

    In my code, I am using an array xyz of 10 objects. When I am trying to access an element of the array using an unsigned int index like this: xyz[level], I get 'Buffer overrun' warning. Logically, I am pretty sure that level won't exceed 10. How to avoid this warning?

  • Multithreading A Function in VB.Net

    - by Ben
    I am trying to multi thread my application so as it is visible while it is executing the process, this is what I have so far: Private Sub SendPOST(ByVal URL As String) Try Dim DataBytes As Byte() = Encoding.ASCII.GetBytes("") Dim Request As HttpWebRequest = TryCast(WebRequest.Create(URL.Trim & "/webdav/"), HttpWebRequest) Request.Method = "POST" Request.ContentType = "application/x-www-form-urlencoded" Request.ContentLength = DataBytes.Length Request.Timeout = 1000 Request.ReadWriteTimeout = 1000 Dim PostData As Stream = Request.GetRequestStream() PostData.Write(DataBytes, 0, DataBytes.Length) Dim Response As WebResponse = Request.GetResponse() Dim ResponseStream As Stream = Response.GetResponseStream() Dim StreamReader As New IO.StreamReader(ResponseStream) Dim Text As String = StreamReader.ReadToEnd() PostData.Close() Catch ex As Exception If ex.ToString.Contains("401") Then TextBox2.Text = TextBox2.Text & URL & "/webdav/" & vbNewLine End If End Try End Sub Public Sub G0() Dim siteSplit() As String = TextBox1.Text.Split(vbNewLine) For i = 0 To siteSplit.Count - 1 Try If siteSplit(i).Contains("http://") Then SendPOST(siteSplit(i).Trim) Else SendPOST("http://" & siteSplit(i).Trim) End If Catch ex As Exception End Try Next End Sub Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim t As Thread t = New Thread(AddressOf Me.G0) t.Start() End Sub However, the 'G0' sub code is not being executed at all, and I need to multi thread the 'SendPOST' as that is what slows the application.

  • Should I call class destructor in this code?

    - by peterg
    I am using this sample to decode/encode some data I am retrieving/sending from/to a web server, and I want to use it like this: BOOL HandleMessage(UINT uMsg,WPARAM wParam,LPARAM lParam,LRESULT* r) { if(uMsg == WM_DESTROY) { PostQuitMessage(0); return TRUE; } else if(uMsg == WM_CREATE) { // Start timer StartTimer(); return TRUE; } else if(uMsg == WM_TIMER) { //get data from server char * test = "test data"; Base64 base64; char *temp = base64.decode(test); MessageBox(TEXT(temp), 0, 0); } } The timer is set every 5 minutes. Should I use delete base64 at the end? Does delete deallocates everything used by base64?

  • Git/SVN for asp.net development instead of VSS?

    - by jrutter
    At work, we are using ASP.net 2.0 and VSS. VSS is a beast, we are continually having issues with people checking out files and there is no branching - makes it crazy. I know SVN/GIT is mainly used by open source developers, are there any downsides to ASP.NET developers using it? I have been pushing for SVN internally, but am thinking GIT might also be a great option. Our team is spread across 3 continents.
