    - How to: Implement 'Always on Top' option Hi, Have a look at my code: Code Block private void button1_Click( object sender, EventArgs e) { int dhwnd; int hwnd; int wc; int rval; string wname = new String ( ' ' , 260); int index; dhwnd = GetDesktopWindow(); hwnd = GetWindow(dhwnd, GW_CHILD); wc = 1; index = 0; while ((hwnd != 0)) { StringBuilder sb = new StringBuilder (1024); rval = GetWindowText(hwnd, sb, sb.Capacity); if (sb.ToString().Trim().IndexOf( "Form1" ) > -1) { Console .WriteLine( "hwnd: " + hwnd.ToString() + ", Name: " + sb.ToString().Trim()); RECT rect = new RECT (); if (GetWindowRect(hwnd, out rect)) { SetWindowPos(hwnd, HWND_TOPMOST, rect.X, rect.Y, rect.Width - rect.X, rect.Height - rect.Y, SWP_SHOWWINDOW); } return ; } hwnd = GetWindow(hwnd, GW_HWNDNEXT); } } This Code works on Vista x64.

    - Converting C to C++ Hi all. I've taken the liberty in "dissecting" some code so i can understand it better. However, im having a hell of a time trying to figure out how to convert it from C to C++ . My error is this: error C2664: 'recvfrom' : cannot convert parameter 6 from 'unsigned int *' to 'int *' Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast Error executing cl.exe The offending code is as follows: if ((respStringLen = recvfrom(sock, echoBuffer, ECHOMAX, 0, (struct sockaddr *) &fromAddr, &fromSize)) != echoStringLen) DieWithError("recvfrom() failed"); if (echoServAddr.sin_addr.s_addr != fromAddr.sin_addr.s_addr){ fprintf(stderr,"Error: received a packet from unknown source.\n"); exit(1); } Im hoping i dont have to change too much, googling around i see others with the same problem but no solution. Any suggestions would be greatly appreciated. Thanx in advance! Tag: Visual C++ General DDK Visual C++

    - Makefile newbie - don't know where to start You can easily done this with your development machine(read the link provided above). But I don't think it is easy to make this happen in random machine(which maybe a new installed machine with nothing in it). Basically, you are tring to make first.exe a build tool, if you add a textbox in first form to allow user to specify the project file path to be build with, and re-direct the output message to another multi-line textbox on first form, wow, its a builder. A build process relies on many environments on your machine, for development machine, these environments has been set up correctly with the installation of visual studio, so simple call vcbuild.exe with appropriate arguments is enough. For a random machine, at least you will make sure following things: 1. Correct version of .NET Framework has been installed in target machine. 2. Everything that second.proj relies on are ready in their suitable places, resources, header files, source files, libraries, assemblies, and more. 3. Everything that first.exe relies on are ready in their suitable places, if you invoke vcbuild.exe, then you will distribute all tools that vcbuild.exe may calls during processing, e.g. cl.exe, link.exe, and more. 4. and maybe more... Put them all together, I'd recommend you install visual c++ 2005 express in target machine, with which you can build second.proj easily. hope it makes sense rico Tag: Visual C++ General DDK Visual C++

    - Mixed Mode : Should definitions be in the headers when creating static mixed lib? Hi, I found an elegant solution for my problem. (Thanks to Nishant's Book !) This solution will reduce the overhead of forcing C++/CLI syntax when native developers are trying to use my classes as well. Still memory management is a big topic, I think I have to study further before delving in. Thank you, -- Sunkyu // ============ LIB HEADER ====================== #include <string> #include <msclr\auto_gcroot.h> namespace Minerva { namespace MixMode { class MixMe { protected: msclr::auto_gcroot<System::Xml::XmlDocument^> _doc; public: MixMe(const std:: string& fileName); virtual ~MixMe(); }; } } // ============ LIB SOURCE ====================== #include "MixMe.h" using namespace Minerva::MixMode; using namespace System::Xml; MixMe::MixMe(const std:: string& fileName) { _doc = gcnew XmlDocument(); } MixMe::~MixMe() {} // ============ APP CODE ====================== #include "MixMe.h" #include <stdio.h> using namespace Minerva::MixMode; int main(int argc, char* argv[]) { MixMe* mix = new MixMe("Hello, world"); delete mix; return 0; } Tag: Visual C++ General DDK Visual C++

    - Function Definition - pointers I need to have a function that returns an address of the first element of the array or pointer basically and be able to read this pointer from another function. I am not sure about the syntax, I keep on getting errors. Here is what I tried: Code Snippet double* get_vector(); // supposed to return a pointer //in the function, at the end I return an address of a variable then in another function to write this to an array defined in my new function, I do: Code Snippet double *temp; temp=get_vector(); then I tried many other things but it doesn't work and if I don't get syntax errors, I am not getting the desired output. Do you know how to fix this Thanks. Tag: Visual C++ General DDK Visual C++

    - file seek then read thread-safety Frank, I'm using SetFilePointerEx and ReadFile functions. I'm guessing fseek and fread uses these functions underneath so those two calls also block out other threads Sdi, You're absolutely correct that another seek can come in between a seek-then-read operation and I'll need a critical section for it. It sounds like I'll need to create a windows equivalent of pread: int pread(handle, location, size, data*) { enter critical section seek read leave critical section } Thanks.

In other words, the "<" comparison operator causes a syntax error but "<=", "==", "!=" are just fine. This is because the compiler is confusing the "<" with the start of a list of template parameters. How do I tell it that that is not the case Tag: Visual C++ General DDK Visual C++

    - How to export a regular C++ class correctly from DLL Viktor.Prehnal wrote: Create a special header file in your DLL project that contains code similar like this. #pragma once #ifdef _GRIDDEPCTRLS #define GRIDDEPCTRLS_CLASS AFX_CLASS_EXPORT #else #define GRIDDEPCTRLS_CLASS AFX_CLASS_IMPORT #endif //_GRIDDEPCTRLS Than define your export class with that macro, e.g.: class GRIDDEPCTRLS_CLASS ECDialogClass { }; and it should work. We are using it a lot and did not encounter the problem you are describing. REM1: Do not forget to put _GRIDDEPCTRLS macro to your preprocesor configuration of your DLL. Thanks for reply. It returns to the beginning of the question now. Actually you told me is the exactly the Dll project being created with AppWizard. Once the class is declared with the GRIDDEPCTRLS_CLASS, all the members of the ECDialogClass will be exported. But I realy don't like to export those inline (and non-virtual) member functions because that cause the dll export-tabel becoming very large and being loaded more slowly. Expl: Code Snippet class GRIDDEPCTRLS_CLASS ECDialogClass { public : function1(); // Will be exported from the dll okay. function2() // Should have not being exported here. { return (m_dwSpecialColor);}; private : DWORD m_dwSpecialColor; }; Note the function ECDialogClass::function2 will be written to the dll by compiler & linker. However, modified class also can work just fine for applications: Code Snippet class GRIDDEPCTRLS_CLASS ECDialogClass { public : function1(); // Will be exported from the dll okay. //function2() // Should have not being exported here. //{return(m_dwSpecialColor);}; public : DWORD m_dwSpecialColor; }; But for a coder, because the m_dwSpecialColor should not be modified directly, It should not be a public member.

    - static operator += not recognized from outside assembly Brian Kramer wrote: It would be more helpful if you gave complete (but minimal) code. Have you tested the case that does compile When I defined it your way (a two-parameter operator+=), the compiler appears to use a temporary instance of X, rather than the x upon which I invoke operator+=. I have switched from using ' public static X operator += (X x,int amt);' to using ' public static X operator + (X x,int amt);' and this works properly. Evidently the first form is non-CLS compliant for C++/CLI while the second is CLS compliant for C++/CLI and the use of 'x += 3' will actually call the second form as 'x = x + 3' if the first form does not exist. This may explain why Microsoft has botched the implementation of the first form in both the compiler error case I found and the temporary instance case you found, and which I also saw when called internally in the same assembly. In essence the bad implementation seems to be saying to use the second form and not the first, since Microsoft has not got the first form correct.. For completeness sake, however, here is the code in an assembly using the first form which gives the error when called from outside the assembly: Header file ------- ---- #pragma once using namespace System; namespace TSEAssembly { public value class TestOperatorEmbedded { public: static TestOperatorEmbedded operator += (TestOperatorEmbedded it,int amt); static TestOperatorEmbedded operator -= (TestOperatorEmbedded it,int amt); int val; }; } Source file ------- --- #include "stdafx.h" #include "TSETestOperatorEmbedded.h" TSEAssembly::TestOperatorEmbedded TSEAssembly::TestOperatorEmbedded::operator += (TestOperatorEmbedded it,int amt) { TestOperatorEmbedded rit(it); rit.val += amt; return(rit); } TSEAssembly::TestOperatorEmbedded TSEAssembly::TestOperatorEmbedded::operator -= (TestOperatorEmbedded it,int amt) { TestOperatorEmbedded rit(it); rit.val -= amt; return(rit); } ---------------- Trying to call this from outside the assembly via: TSEAssembly::TestOperatorEmbedded emb; emb.val = 5; emb += 6; // the compiler error occurs here leads to a compiler error. However having the equivalent code inside the assembly compiles fine. The result in the latter case is as you say above, and not like it should work in any case. Using the seconf form always works properly. Since the first form is non-CLS compliant and I now know enough to use the second form, which always works, I am not going to bother issuing a bug report, but feel free to do so if you like.

    - CreateFile and GetVolumeInformation fail Hi there. I'm trying to get the informations - filesystem name, etc - of disk partition, and if unformatted volume, want to get like "unknown filesystem or unformatted". Also, I want to get the informations of partition which is formatted by linux filesystem and unmounted if linux filesystem driver is running. So I tested simply as follow: #include <stdio.h> #include <Windows.h> #include <Winbase.h> #include "test.h" #define DISK 2 #define PARTITION 3 main() { int i, j; char DevName[256]; int FileSystemFlag; char FileSystemName[64]; int BytesReturned, LastError; HANDLE hdrive; EXT2_PARTITION Ext2Partition; /* open */ hdrive = CreateFile(" \\\\.\\ " DEVICE_NAME, GENERIC_READ | GENERIC_WRITE, 0, \ NULL, OPEN_EXISTING, FILE_FLAG_NO_BUFFERING, NULL); LastError = GetLastError(); if (!DeviceIoControl( hdrive, IOCTL_EXT2_PARTITION, &Ext2Partition, sizeof(EXT2_PARTITION), NULL, 0, &BytesReturned, NULL)) { CloseHandle(hdrive); // return; } CloseHandle(hdrive); for(i=0; i<DISK; i++) { for(j=1; j<PARTITION; j++) { sprintf(DevName, " \\Device\\Harddisk%d\\Partition%d ", i, j); GetVolumeInformation(DevName, NULL, 0, NULL, NULL, &FileSystemFlag, FileSystemName, 63); } } } However, CreateFile failed and LastError code was ERROR_FILE_NOT_FOUND. DEVICE_NAME is defined as service name of the driver. Also, even in case of Harddisk0\\Partition1 which is NTFS, nothing was pointed to FileSystemName in GetVolumeInformation. It fails too though DevName is "C:" and LastError code is ERROR_INVALID_NAME. but I want to get the information from even unmounted volume. What is wrong I wish your advices.

Re: Visual C++ General DDK

einaros

If you want a general introcution to the inner workings of windows, you should check the Sysinternals book (I'm sure it's linked off the sysinternals.com site). I haven't read any device driver books apart from "The Windows 2000 device driver book", and that was pretty good. There are probably more updated resources available, though. I recommend you spend some time at http://www.osronline.com/.

Re: Visual C++ General DDK

Simple Samples

For books, the answer to most questions is the book reviews in accu.org; for example:

http://accu.org/index.php/book_reviews url=search.xqy%3Fx&term=Windows+drivers

For this, however, there is not much more than the book Einar suggested.

Re: Visual C++ General DDK

Bruno van Dooren

Read this blog post of mine.

It contains 2 links to introductory articles on device driver programming that I wrote. The articles themselves also have information on where to start and which tools / frameworks to use.

http://msmvps.com/blogs/vandooren/archive/2006/06/15/Is-it-possible-to-create-_2800_USB_2900_-device-drivers-with-Visual-C_2B002B003F00_.aspx

For books, read 'The windows driver model' by walter oney and 'Windows system internals' by mark russinovich.

Both books are a must-read if you are going to do driver programming.
