I have tree control object created using CTreeCtrl MFC class. The tree control needs to support rename. When I left click on any of item in Tree the TVN_SELCHANGED event is called from which I can get the selected item of the tree as below : HTREEITEM h = m_moveListTree.GetSelectedItem(); CString s = m_moveListTree.GetItemText(h); H...
For example, if I declare a long variable, can I assume it will always be aligned on a "sizeof(long)" boundary? Microsoft Visual C++ online help says so, but is it standard behavior? some more info: a. It is possible to explicitely create a misaligned integer (*bar): char foo[5] int * bar = (int *)(&foo[1]); b. Apparently, #...
Suppose I have the following code: class some_class{}; some_class some_function() { return some_class(); } This seems to work pretty well and saves me the trouble of having to declare a variable just to make a return value. But I don't think I've ever seen this in any kind of tutorial or reference. Is this a compiler-specific t...
Is the a VS2005 C++ compiler flag like the Xmx???M java flag so I can limit the heap size of my application running on Windows. I need to limit the heap size so I can fill the memory to find out the current free memory. (The code also runs on an embedded system where this is the best method to get the memory usage) ...
My C(++) program, written and compiled using Visual C(++)/Visual Studio, runs fine on my own machine, but refuses to run on another machine. The error message I get is "This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem." ...
I have just installed a build server with a 64 bit windows server 2008 for continuous integration. The reason I choose a 64 bit server was to have more than ~3Gb of RAM. I had hopes that this machine would provide blazing fast builds. Unfortunately, the result are lacking greatly to say the least. My desktop provides faster builds tha...
I'm using C++ and accessing a UNC path across the network. This path is slightly greater than MAX_PATH. So I cannot obtain a file handle. But if I run the program on the computer in question, the path is not greater than MAX_PATH. So I can get a file handle. If I rename the file to have less characters (minus length of computer name)...
Hello all, Is there any API to get the currently logged in user's name and password in Windows? Thank you in advance. ...
Here's the code I want to speed up. It's getting a value from an ADO recordset and converting it to a char*. But this is slow. Can I skip the creation of the _bstr_t? _variant_t var = pRs->Fields->GetItem(i)->GetValue(); if (V_VT(&var) == VT_BSTR) { char* p = (c...
While I certainly understand the purpose of buffer annotations, I can't see what kind of errors __callback detects. Any ideas, examples? ...
What is the best way to disable the warnings generated via _CRT_SECURE_NO_DEPRECATE that allows them to be reinstated with ease and will work across Visual Studio versions? ...
What are the compelling features of MFC? Why would you select it for a new project? ...
My ClickOnce application uses a third party tool that requires the Visual C++ 2005 redistributable. The third party tool will not work if only the VC++ 2008 redistributable is installed. However, in Visual Studio 2008, the ClickOnce prerequisites do not allow a version to be specified for the VC++ redistributable; it will add a VC++ 2008...
Suppose you have a fairly large (~2.2 MLOC), fairly old (started more than 10 years ago) Windows desktop application in C/C++. About 10% of modules are external and don't have sources, only debug symbols. How would you go about reducing application's memory footprint in half? At least, what would you do to find out where memory is consu...
Hello all, Is there a direct API to get the currently logged in user's name with the domain? So, it would return something like "domain\user" when a machine is on the domain, but at the same time it would return "user" when the machine is not on the domain? If there's not, what's the best way to get this information? I noticed there's ...
I've been reading the legacy code,which invloves in the customized memory pooling system, then I found that the code uses _aligned_malloc. I wonder what is this function and when do I have to use it. ...
I want to access the call stack at runtime in a Native C++ application. I am not using the IDE. How do I display the call stack? Update: I have a function which is called from many points all over the application. It crashes on rare occasions. I was looking for a way to get name of the caller and log it. ...
I want to execute a certain batch file and redirect its console output to a text control in visual c++ or redirect the console output at the same time the logs/echo are showing. ...
In Visual Studio, we've all had "baadf00d", have seen seen "CC" and "CD" when inspecting variables in the debugger in C++ during run-time. From what I understand, "CC" is in DEBUG mode only to indicate when a memory has been new() or alloc() and unitilialized. While "CD" represents delete'd or free'd memory. I've only seen "baadf00d" ...
[NOTE: This questions is similar to but not the same as this one.] Visual Studio defines several dozen "Macros" which are sort of simulated environment variables (completely unrelated to C++ macros) which contain information about the build in progress. Examples: ConfigurationName Release TargetPath D:\work\foo\win\R...
