I have a window created with CreateWindowEx, with a caption. When I load the text using EM_STREAMIN the opening line of the text goes into the caption, replacing the intended title. How do I prevent this, so as to retain the intended caption ?

Although this is a very old question it may still be of interest. I have just been running GSL (1.8) in Visual Studio 2005, and had much the same problem with unrecognised symbols, even though I could see they were in the Libs, libgsl_dll_d.lib, libgslcblas_dll_d.lib. In my case I was using the Hybrid and Newton root finding algorithms. The symbol that was missing was gsl_multiroot_fdfsolver_gnewton. Eventually I found that I had to add GSL_DLL to the Property Page: Configuration Properties: C/C++: Preprocessor, Preprocessor Definitions. That surprised me, but clearly it is the way to link up with the GSL code. Raymond Mercier

In the end it was easy enough to run the function with its loop in a thread. "ThreadProcTCP" is a rather involved module, with a loop, but it all works fine.

if (hChild)
GetExitCodeThread( hChild, &dwExitCodeThread );
if (dwExitCodeThread!=STILL_ACTIVE)
hChild = CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)ThreadProcTCP, hWnd, 0, &dwChild );

Thanks, but I don't see how that can be made to deal with a loop. Raymond

Thanks, but I have so little experience with threads, I will have to bone up on it. Raymond

I have in a C++ module a for loop that can take some minutes to complete. I would like to add a pause/resume feature, and would also like to be able to stop it. However while the loop is running the program is totally unresponsive. Is there anything to be done ? Raymond Mercier

>>"I can't believe that you went this many years without it" (PlatformSDK). I don't know why you think that I do not already have the headers, since they come with the full installation of Microsoft Visual Studio .NET 2003, including its PlatformSDK. In wingdi.h I find the condition _WIN32_WINNT >= 0x0500, which is obviously satisfied in the XP that I am using. From I see that for XP _WIN32_WINNT = 501 So I only need to add #define _WIN32_WINNT 501 before windows.h, and then I can call the function I need. That is of course the only point that I had overlooked. Raymond Mercier

Thanks for the tip, but I should have mentioned that I have been compiling with VS 6 with Net Framework 1.1. Meanwhile I have managed (sort of) with these lines, which do allow me to get the function. I still fail to see why I have to go through all this, but not for AddFontResource, and I still have to put 0x10, since FR_PRIVATE is not recognized. static FARPROC fpAddFontRes,fpRemoveFontRes; HMODULE hLibrary; hLibrary=LoadLibraryW(L"gdi32.dll"); fpAddFontRes=GetProcAddress(hLibrary,(LPCSTR)"AddFontResourceExW"); fpRemoveFontRes=GetProcAddress(hLibrary,(LPCSTR)"RemoveFontResourceExW"); ..... nFontLoad=(*fpAddFontRes)(Bact,0x10,0); At least this works fine ! Raymond Mercier

Sorry, this failed to appear ! #define UNICODE // Save as Unicode -Codepage 1200 #include <windows.h> #include <Winbase.h> #include <WinGDI.h>

I am trying to include AddFontResourceEx(Fontname,FR_PRIVATE,0); but get the error message that the function and FR_PRIVATE are undefined. Of course I have wingdi.h in the opening lines : #define UNICODE // Save as Unicode -Codepage 1200 #include ; #include ; The error is produced when I try to compile. I have added gdi32.lib to the command line. What am I supposed to do about gdi32.dll ? Thanks for any help Raymond Mercier

Thanks again. It does as you say. Great game, this Vista ! Raymond

Thanks, that has cured it. Now I have to see how to run the program in debug mode within VisualStudio, but as administrator. Raymond

I want to install the file data.bmp in system32: hFile = CreateFile((L"c:\\windows\\system32\\data.bmp"), GENERIC_READ|GENERIC_WRITE, FILE_SHARE_READ|FILE_SHARE_WRITE, NULL, CREATE_ALWAYS, 0, NULL); When I run this hFile is given a value, so I write to the file, and close it. Why doesn't it appear in system 32 ? I have no trouble writing to other folders, but not to Windows, or even to C:. The problem seems to be pecular to Vista, and certainly doesn't arise on XP. Raymond Mercier

Thanks, but I have had a look at the site you mention, and can't see how it helps. I am looking for some kind of log file in the server which would record the fact that the file has actually been downloaded from the server to the client. I feel that if I knew something about asp I would know the answer. Raymond

Unfortunately the code that I wrote in the question Download Demo href="prog/Demo.zip" here got treated as an active line. So I repeat the question, is there some way that a notification of this copying can be recorded in the server ? For some people there must be an obvious solution, but not to me ! Thanks, Raymond Mercier

I have a website that allows the file Demo.zip to be copied from the server in the usual line:

Thanks, but I have already gone through that page on the way to Crypto. Raymond

That is what I did, and was able to compile some of the various crypto programmes, but each one has a different cryptolib.h, and none of them seem to be right for the aestest programmes. Raymond

Graham, Going back to the aestest samples I see that I need various headers. #include "cryptlib.h" #include "aes.h" // AES #include "modes.h" // CBC_Mode< > #include "filters.h" // StringSource These are not given in that CodeProject page, but when I look around I find something under these names in http://www.koders.com/cpp/... but the headers I find there sre not right for aestest. So where or the correct headers ? I had more luck in compiling crypto50 etc, but the versions of cryptlib.h in those versions of crypto are clearly not right either for the aestest examples. Raymond

Thanks to all who have taken the trouble to reply, especially for the link to the AES code. I think now that the 'phone home' method is a bad idea. I had put out a limited feature demo, but did feel that it would be better to make it time limited. My experience is that either scheme can lead to a sale. Raymond
