• JesseD70 msvcr80.dll problems: version 8.0.50727.363 versus 8.0.50727.42

  I have a really strange problem. I'm using Visual C++ 2005 Express installed, and everything worked fine ever since I installed it. But at some point during the last few days something broke, and now I can't run my programs anymore. I started to investigate, and found this: A simple test program like this (test.cpp): #include <stdio.h> int main() { printf("Hello, world!\n"); } when compiled with cl test.cpp /MD results in three files, test.exe, test.exe.manifest and test.obj. The manifest contains: < xml version='1.0' encoding='UTF-8' standalone='yes' > <assembly xmlns='urn:schemas-microsoft-com:asm.v1' manifestVersion='1.0'> <dependency> <dependentAssembly> <assemblyIdentity typ ...Show All

• Programm3r Monitoring Child Process..

  Hi, I am writing an application which silently install netfx.exe redistributable. I want to catch events(start and end of the child process) and error codes in case if execution fails. I have tried using Piping but not sucess. I am not getting any bytes in the pipe for all the use cases which i have tried. I also tried one C runtime function which creates and wait for the termination of the process. It also return the Error codes for netfx.ex. But i am looking for more flexible solution like piping. Could anyone help me figure understand why piping is not working and how _wspawn() [i think i got the name right] works. Is there any other ways i can monitor and get error codes.

• Tovdb Integrated environment loses keyboard after debugging

  When exiting the debugger prematurely, (ie debug | stop debugging from a breakpoint or abort on an exception or assert), more often than not the keyboard interface is broken. The only keystrokes the IDE recognizes would be the short cut to a main menu, and while the menu is displayed, then any keystrokes seem to flow into the active window. I have to quit and reload Visual Studio to fix this. No other software is affected. Any idea what's going on Thanks, dw You don't specify what type of program it is, such as console program, but the program is probably doing something it should not do. Check the Task Manager to see if your program is still shown as a process (in the Processes tab) after y ...Show All

• celinedrules MoveWindow for dialog has no effect when invoked by message handler

  Problem: MoveWindow function for a dialog appears to not work when called from a message handler. Details: My dialog-based application needs to work in both landscape and portrait screen modes. Not only that, but it needs to detect when the user has chosen to rotate his/her display from portrait to landscape or vice versa, and adjust itself accordingly. When in portrait mode, the dialog is 1024h x 768w. When in landscape mode, it is 768h x 1024w I added a message handler ON_WM_SHOWWINDOW, which is called when the application is first displayed. I also added a message handler WM_DISPLAYCHANGE which is called when the system detects an aspect ratio change. Both of these message handlers call a member function that does the follow ...Show All

• Bulldog.NET Hello World app not "finding" header files?

  I am re-teaching myself Visual C++, and I am starting with the Hello World app (that I think we've all created early in our C++ lives). I get compiler errors that should be covered by the header files I'm including in the project. What am I doing wrong here Your reply just ended about 2 hours of painful, hair-pulling frustration. Thanks a million!! You need to inlcude the header file after the PCH header file otherwise it is ignored. Try: #include <stdafx.h> #include <iostream> You need to include <iostream> not <iostream.h> Yep i like this reply!! Thank goodness someone else had this problem before me otherwise i would've been there for hours!! thanks ...Show All

• DanBaumbach 'Is' in C++

  Hi! In C#, there is a keyword named 'is'. It compares whether one type can be converted into another. Is it possible to do something like this in C++ Thank you You can use safe_cast. See http://msdn2.microsoft.com/en-us/library/23b7yy6w.aspx . Ok, but my problem is a bit different. Perhaps my question was not significant enough. I've a class 'A', a class 'B' and a class 'C'. 'B' contains a property 'foo' whose type is 'A'. 'C' inherits from 'A'. Some other classes ('D' and 'E'), too. Now I want to check whether 'B' points to an instance of 'C'. 'B' could also point to an instance of 'D' or 'E'. In C#, it would be: if(B.foo is C) {  // .... } try { C^ c = safe_cast<C^>(B->fo ...Show All

• Prodigal Son Unmanaged C++ and VS2005: Hidden .NET Requirements?

  Hi everyone. While developing some unmanaged C++ DLL that uses COM and ATL, I've been having issues with deploying the DLL to other machines - those without .NET Framework v2. I've found out after some digging that changing the runtime library from its default to one of the debug libraries (and none of the DLL ones) removed this dependency, but introduced some crashes that im not entirely sure are related to my own application's logic. What is the proper way of creating unmanaged c++ DLLs in VC++2005, Who use ATL and COM Thanks in advance. Thanks for your answers, I've marked the one more relevant as the 'answer' for this post. I hope that its the source of the issues i was having. Just to be sure i'm d ...Show All

• Lucas Pasquali Presenting a C++ library (.lib) for use in C# project

  I have a collection of C++ programs and the C++ libraries they use. The libraries currently compile to a .lib format. Changing the project property to use a .dll results in multiple reference errors. Without having to go through the entire collection of source files, is there a way to create any kind of project in a .NET language that would provide a "wrapper" for the existing .lib files so that they could be used in that environment. Thanks. These posts really helped me along. The only trouble i'm having now are some more complex datatypes than a simple double. How would I go if the function in the lib expects some char* which is additionally used as a callback reference The definition of the function from the .libs head ...Show All
