Anyone have any idea how one would programmatically detect the presence of a personal firewall?

Rich Edit control works ok but doesn't allow setting of TF_PLAINTEXT: SendMessage(mhEditCtrl, EM_SETTEXTMODE, TM_PLAINTEXT, 0); returns 0 which is supposed to indicate success according to the api docs. But it's not plain text because I can drag formatted text (with various fonts etc) into the...

random_shuffle produces the same random order each time. Is there any way the seed std::random_shuffle? (srand didn't help). #include <vector> #include <algorithm> #include <iostream.h> typedef struct {int i;} TESTSTRUCT; using namespace std; int main() { vector<TESTSTRUCT> vec...

I have a simple windows program which uses some wininet functions. However, I get &quot;unresolved external&quot; for all the wininet functions. When that happens in Visual Studio it means I need to add &quot;wininet.lib&quot; to the linker settings. However, I don't know how to do this on the...

In Visual Studio Project Settings -> c/c++ -> Code-Generation -> Use run-time library has three options: &quot;SingleThreaded&quot;, &quot;Multithreaded&quot;, &quot;Multithreaded DLL&quot;, (and these again for debug). Should I set this to &quot;Multithreaded &quot;if I'm using CRT functions...

When using the wininet function InternetFindNextFile(HFILE, WIN32_FIND_DATA*) to read an ftp directory, is the date for each remote file represented by any of the values in the WIN32_FIND_DATA struct? There are three date values in WIN32_FIND_DATA: ftCreationTime, ftLastAccessTime...

Anyone ever seen this warning when using winsock: Command line warning D4027 : source file 'wsock32.lib' ignored It goes away if I take wsock32.lib out of the linker settings (but of course so does winsock!). It doesn't seem to affect anything but I would like to get rid of it. Thanks in advance.

How do I get the local port of a connected socket? --Will Duty wduty@radicalfringe.com

Having witnessed part of the horror of yesterday's events from my midtown Manhattan office window (before our building was evacuated), I would like to express my deepest respects and/or condolences to anyone who was directly or otherwise affected by yesterday's events. - Sincerely William C...

I was having problems iterating/reading through files from an ftp server. When reading the whole of each file everything was fine but attempting to read just the first few bytes of each file caused a strange behavior: every second and third call to FtpOpenFile() failed with error 12003. It turns...

Is there any win32 way to split a file into two files? I mean doing so &quot;in place&quot;. For example, if I have a 1GB file and I want the first 500MB's to be one file and the second 500MB's to be another file, can it be done? I can easily do this by getting a file handle, copying the...

I have a component which fires a bunch of events. I have another component which is a wrapper for that component. The wrapper derives from DispEventSimpleImpl and therefore uses DispEventAdvise to hook up to the events in the first component. I found that although I was receiving all the events...

I am subclassing a dialog and want to put the callback procedure into a class which manages that part of an application. I get the following cast error: cannot convert from 'long (__stdcall ManagerObj::*)(struct HWND__ *, unsinged int, unsigned int, long)' to 'unsigned long' This occurs when...

I often see in programs (such as visual studio) a prompt indicating that a file which you have open has been modified by another user and whether or not you want to reload it. How would you go about doing this? I usually use CreateFile for windows programs to read/write files, but I usually...

Calling Unadvise() in a connection point sink causes an access violation in ReleaseMinDependency build but not in Debug build. Anyone ever seen this? --Will Duty wduty@radicalfringe.com

I am writing a program which will require allocating and deallocating a potentially large number of buffers. Is there any advantage to using malloc vs new vs GlobalAlloc vs LocalAlloc etc. ? I have used all of these methods to the same effect and never noticed any performance difference. Any...

I am able to fire events from an ATL object as long as the object is created as a full control. However, if the object is a simple ATL object, the component still compiles, registers, and works, except for the event-firing functionality. Watching the event firing code, the IDispatch pointer from...

Does anyone know how to make the system-clock dialog appear? --Will Duty wduty@radicalfringe.com

I have three child windows in the main HWND of a program. I am subclassing one of them so as to be able to do some custom mouse-handling in that child. The callback I assign only seems to stick if I use GetChildFromPoint() when I switch the procedures. Attempting to use the window handle itself...

I have a program where I allow the user to determine the length of the selected text in an edit control. The user makes a menu selection which calls a function which gets the menu selection length (or the length of text in the whole control if there is no selection). The length then shows up in...
