  • Compiler doesn't find methods from base class

    - by Paul
    I am having a problem with my virtual methods in a derived class. Here are my (simplified) C++ classes. class Base virtual method accept( MyVisitor1* v ) { /*implementation is here*/ }; virtual method accept( MyVisitor2* v ) { /*implementation is here*/ }; virtual method accept( MyVisitor3* v ) { /*implementation is here*/ }; class DerivedClass virtual method accept( MyVisitor2* v ) { /*implementation is here*/ }; The following use causes VS 2005 to give: "error C2664: 'DerivedClass::accept' : cannot convert parameter 1 from 'Visitor1*' to 'Visitor2 *'". DerivedClass c; MyVisitor1 v1; c.accept(v1); I was expecting the compiler to find and call Base::accept(MyVisitor1) for my DerivedClass as well. Obviously this is not working, but I don't understand why. Any ideas? Thanks, Paul

  • printing long compilation lines with MS NMAKE

    - by Elazar Leibovich
    I have a legacy MS NMAKE Makefile I need to fix a few bugs in. There are some very long command lines I wish to debug that are being executed using the NMAKE trick of "inline files": dep: cmd @<<tmpfilename cmd_args.. << When changing the line to dep: echo cmd @<<tmpfilename cmd_args.. << NMAKE complains that the line is too long. Is there any other trick I can apply in order to view the command line NMAKE is actually executing?

  • Problem in VS2010 IDE in analog monitor in a dual-monitor setup

    - by Samik R.
    I am using VS2010 Premium with a dual-window setup. One of the monitors is on a digital (DVI) cable and other one is on an analog (VGA) cable. I have noticed that when I put VS2010 in the analog monitor, there are garbled texts and refresh problems while coding and/or scrolling. This does not seem to be the case when I put VS2010 in the digital monitor. Note that, I am not expanding VS IDE to use 2 screens, just making it 1 full screen, either analog or digital. Has anyone else experienced this problem? I also work with VS2008 and have not seen this problem in either screen. VS IDE has started using WPF from the 2010 release, not sure if this has something to do with it.

  • Where can I find a tool to convert a VS solution to a gcc makefile?

    - by Tim
    I know about CMake and bakefile already, but that is not what I am looking for. Is there a tool that will generate a makefile given a VC project? (or at least a first attempt at one) so I don't have to do all the work by hand? Alternatively, is there a tool that makes CMake files? Edit: Following the link below leads me to this: http://www.winehq.org/docs/winemaker That is a great help. I have not tried it yet.

  • ACCESS 2003 Excel 2003 : VBA for opening Excel file from Access and copying a pictre from excel the

    - by Justin
    So I have an excel workbook that has a nice global map of shaperange objects. With some very simple code I can change the colors, group and ungroup collections of countries into arrays, etc...and it works pretty well. However, I would like to bring this into Access. So I could copy and paste all the shapes into an access form manually, but then they become pictures and I cannot change the colors of the countries (shaperange objects) to have the map act interactively as I can in excel. So I am thinking that I know how to use excel functions from access, and how to open excel from access. Is there a way to copy an object from excel (I know the file name and the shape name that i mean to copy everytime), and bringing it back to access to paste on a form? Atypical, I know, all my Access questions are. Thanks!

  • CodeRush Tricks of the Trade

    - by dr. evil
    I was using CodeRush quite while ago and now I'm planning to use it again. I've install the trial but I forgot all cool features except Alt + Home (drop a marker). And when you don't know some cool tricks it's really like burning money (since it's not cheap for personal use) What do you like about it? What are your best features? My best feature is marker: Alt + Home (and use escape to go back) P.S Dear Devxpress, if you think I helped you by asking this question I can accept some donations, a free license of CodeRush would be nice! Currently What I like most ps/pi etc. shortcut to create properties cc to create constructors pressing tab to navigate between the references F12 to find references in new cool window Ctrl + Shift + . for recent files Ctrl + Shift + Q for jumping to any function / class fe/fi for "for loops"

  • Effective Method to Manage and Search Through 100,000+ Objects Instantly? (C#)

    - by Kirk
    I'm writing a media player for enthusiasts with large collections (over 100,000 tracks) and one of my main goals is speed in search. I would like to allow the user to perform a Google-esque search of their entire music collection based on these factors: Song Path and File Name Items in ID3 Tag (Title, Artist, Album, etc.) Lyrics What is the best way for me to store this data and search through it? Currently I am storing each track in an object and iterating over an array of these objects checking each of their variables for string matches based on given search text. I've run into problems though where my search is not effective because it is always a phrase search and I'm not sure how to make it more fuzzy. Would an internal DB like SQLlite be faster than this? Any ideas on how I should structure this system? I also need playlist persistence, so that when they close the app and open the app their same playlist loads immediately. How should I store the playlist information so it can load quickly when the application starts? Currently I am JSON encoding the entire playlist, storing it in a text file, and reading it into the ListView at runtime, but it is getting sluggish over 20,000 tracks. Thanks!

  • Fortran: output format dependent on a variable

    - by Flux Capacitor
    I would like to have a FORTRAN write statement formatted to depend on some variable. For example, I could write: write(*,'(3f15.3,3f9.2)') x,y,z,(var(i),i=1,nvari) where nvari = 3 But, what if, in some cases, I actually have 4 variables (i.e. nvari = 4) I would like to write something like this: write(*,'(3f15.3,nvari(f9.2))') x,y,z,(var(i),i=1,nvari) Now, nvari can be anything and the output will work as I like. How can I make something like this work?

  • Ant - using vssadd to add multiple file

    - by mamendex
    Hi, I'm trying to use vssadd task to add a tree of source files to a recent created project on VSS. But it happens to be adding only the folder tree, all files missing. <vsscp vsspath="$/DEV/APL_${version}" ssdir="${vssapl}" serverPath="${vsssvr}"/> The vssadd task displays the name of the folders it's creating: ... (vssadd) $/DEV/APL_0.0.10c/src/domain: (vssadd) $/DEV/APL_0.0.10c/src/mbeans: (vssadd) $/DEV/APL_0.0.10c/src/service: ... The script runs successfully but the files never get in the repository. Trying to use wilcards are no good, the task says it found no matching files and ss returns with a code of 100: <vssadd ssdir="${vssapl}" localPath="C:\Workspace\APL_Build*.*" recursive="true" serverPath="${vsssvr}" comment="Build ${versao} at ${to.timestamp}"/ I've noticed that vssadd does not accept fileset tag either, so I'm kind of lost here. Any tips? tks

  • Code Review "ToDo" Follow Up Items

    - by Blake Blackwell
    I am trying to institute code reviews at my company, and recently we had our first code review meeting. During the meeting, several positive suggestions were made and I added TODO comments in my code for following up. After reading suggestions on here on best practices for code reviews, I would like to follow up on all the items I corrected at the start of the next meeting. Is there a way to add a similar type of comment to the code such as FOLLOWUP so that I can quickly highlight through those code segments in the next meeting?

  • Get Process ID of Program Started with C# Process.Start

    - by ThaKidd
    Thanks in advance of all of your help! I am currently developing a program in C# 2010 that launches PLink (Putty) to create a SSH Tunnel. I am trying to make the program able to keep track of each tunnel that is open so a user may terminate those instances that are no longer needed. I am currently using System.Diagnostics.Process.Start to run PLink (currently Putty being used). I need to determine the PID of each plink program when it is launched so a user can terminate it at will. Question is how to do that and am I using the right .Net name space or is there something better? Code snippet: private void btnSSHTest_Click(object sender, EventArgs e) { String puttyConString; puttyConString = "-ssh -P " + cboSSHVersion.SelectedText + " -" + txtSSHPort.Text + " -pw " + txtSSHPassword.Text + " " + txtSSHUsername.Text + "@" + txtSSHHostname.Text; Process.Start("C:\\Program Files (x86)\\Putty\\putty.exe", puttyConString); }

  • Virtual destructor - How does it work?

    - by Prabhu
    Hello All, Few hours back I was fiddling with a Memory Leak issue and it turned out that I really got some basic stuff about virtual destructor wrong!! Let me put explain my class design. class Base { virtual push_elements()<br>{}<br> }; 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. But my question is "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 is wrong:)

  • What causes my borderless C++ app to crash when overriding WndProc?

  • Making an owner-draw button transparent against its arbitrary background in WINCE

    - by EndsOfInvention
    Hi I am trying to place an owner-draw button transparently onto a background. I have no trouble doing this when the background is a solid colour but if the background is an image I cannot seem to get the correct HDC (handle to device context) to Bitblt() the area that button covers. The HDC that is passed as part of the DRAWITEMSTRUCT gives me a button-default-grey area. If I attempt to get the parent of the HWND and then the device context of that i.e pdc = GetDC(GetParent(hWnd)); then the background that gets BitBlt'd is the background of the last painted window. I hope this question makes sense. this is the code I have: pdis = (LPDRAWITEMSTRUCT)(lParam); hdc = pdis->hDC; button = pdis->CtlID - IDC_BUTOFFSET; //pdc = GetDC((hWnd)); pdc = GetDC(GetParent(hWnd)); hbm = CreateCompatibleBitmap(pdc, Buttons_[button]->bc.Size.cx, Buttons_[button]->bc.Size.cy); SelectObject(hdc, hbm); BitBlt(hdc, 0, 0, Buttons_[button]->bc.Size.cx, Buttons_[button]->bc.Size.cy, pdc, Buttons_[button]->bc.Position.x, Buttons_[button]->bc.Position.y, SRCCOPY); TIA Best regards Ends
