    - CFileDialog As you can see, the OFN_ENABLEHOOK is currently disabled in the code I provided to you. Anyhow: 1. this flag is inserted automatically by the CFileDialog contructor (I read the source code) 2. DoModal asserts if this flag is not used 3. I am not trying to use any special hook - just the default provided by MFC, which works fine with File | Open. My code is in fact almost a replica of the code that the framework uses when it processes OnFileOpen (again, I read the MFC source code) Thanks.

    - Printing strings of TCHAR[] into a file Hi, I'm having difficulty printing strings of TCHAR[] arrays into a file using CreateFile & WriteFile. When I try to write TEXT("1234567") to a file using WriteFile, the result looks like this in the file when opened with notepad or wordpad: 1 2 3 4 5 6 7 There is a space between every character, which makes sense since I'm using UNICODE character sets, but I don't want it to look like this when I'm writing to a file, is there a way to convert between the two character sets I've been trying to come up with a snippet of code to convert TCHAR into char, but no luck so far as the VC++ won't let me declare a variable length array and won't let me access TCHAR[] array by index. For example, I get a run-time error saying that "Access violation writing location" when I do this: myConvertFunction(TCHAR * str, int lengthOfStr) { char tempStr[lengthOfStr]; // <--------- this causes a compiler error str[1] = str[2]; //<-------------this causes a run-time Access violation error } Does anyone have any ideas for me I just want to be able to print TCHAR in UNICODE set properly into a file so that when viewed in wordpad or notepad that there are not spaces between all the characters.

    - Is it just me? Deleting handlers and functions w/VC2005 impossible My comments are too general Ok, I'll be specific, I thought I was. Open a formview app, or Dialog applciation in VC2005. Add a button...call it "Test" and give it a resource ID of ID_TEST Double Click the button and you can add a handler for it. VC2005 adds a functions called OnTest() where you can now add code. Now, this was just a test. My testing is done. I want to delete this button, the function and all remnants that it ever existed so my app is clean again. Or maybe I want to call it a different name, so I'll create a new one with a better name, copy my code and now I want to get rid of the old one. HOW DO YOU DO THAT I could do it with VC6 through the ClassWizard by selecting OnTest() and hitting the <del> key, or right-clicking and selecting delete from the popup menu. I've looked through the MSDN documentation, I've googled it, been a longtime member of ProgrammersHaven, CodeGuru and CodeProject and I haven't been able to figure out how to do this. If I sound frustrated it's because I've spent a good bit of time trying to figure it out and haven't found anything and since this is such a simple basic need (after all, if you can ADD something, shouldn't you be able to just as easily DELETE something ). Yes, I have gone through and deleted code by hand, and I hope I got all the references, but with the various entries VC2005 puts in Intellisense, browser files, resource files, message maps, etc. it's very difficult to know if I got it all. So if you want specifics then there it is. If you know what page of the VC2005 documentation that is on, I'm all eyes. Tag: Visual C++ General CWinFormsView VC2005 Visual C++

    - CHttpFile::SendRequest() hangs Hi all, I am using CInternetSession, CHttpConnection and CHttpFile classes to fetch the asp page. The code seems to run fine for the first time, but it hangs on the second call. here is the code i wrote:- Internet session is initialized in the constructor:- m_pSession = new CInternetSession("CHttpHelper"); CHttpConnection* pServer = NULL; CHttpFile* pFile = NULL; CString server; CString object; INTERNET_PORT port; DWORD a; DWORD dwRet; DWORD dwHttpRequestFlags =INTERNET_FLAG_DONT_CACHE; CString Page; char Buffer[512]; AfxParseURL(url, a, server, object, port); pServer = m_pSession->GetHttpConnection(server, port); pFile = pServer->OpenRequest( CHttpConnection::HTTP_VERB_GET, object, NULL, 1, NULL, NULL, dwHttpRequestFlags); if (pFile != NULL) { pFile->SendRequest(); pFile->QueryInfoStatusCode(dwRet); if (dwRet == HTTP_STATUS_OK) { int nCount = 1; while (nCount > 0) { // Read the Page in a String nCount = pFile->Read(Buffer, 511); if (nCount > 0) { Buffer[nCount] = 0; Page += Buffer; } } } } if (pFile != NULL) { pFile->Close(); delete (pFile); pFile=NULL; } if (pServer != NULL) { pServer->Close(); delete (pServer); pServer=NULL; } Thanks in advance. Note:- 1. The code runs fine when i add an AfxMessageBox("Run"); before pFile->SendRequest(). 2. It works fine with local asp page. Tag: Visual C++ General CWinFormsView VC2005 Visual C++

    - check for process availability using process-id Hi, I have a problem to check for process availability in a CRT based application. I'm using: pid = _spawnlp (_P_NOWAIT, cmd, buf->data, NULL) to start a background process and need help to check if the initialisation of the process fails. _spawnlp allready return an error if something happen during startup like cmd is missing but i want to wait for ~ 0.1 sec and just check for the pid still exists. the problem is that _cwait is blocking until the process is finished. under unix I'm using: waitpid (pid, NULL, WNOHANG) with: WNOHANG The waitpid() function will not suspend exe- cution of the calling process if status is not immediately available for one of the child processes specified by pid. how can I check I the process still exists with only the pid as argument -> thanks for help mfg Andreas Otto Tag: Visual C++ General CWinFormsView VC2005 Visual C++

    - how to GET a binary file using winsock 2 The first time you recv(), you must have received 48byte data, and you truncated it to 8byte(0x47 - 0x6e) by using strlen(). The second time you recv(), you must have received 128byte data, and you truncated it to 3byte(0x94 - 0x18). And I guess the seventeenth byte you have received is 0x96. My suggesting is, use return value of recv() (not strlen()!) to determine your data length. Tag: Visual C++ General CWinFormsView VC2005 Visual C++

    - Obtaining a memory address of a variable returned by a class member function Hello, I'm having some syntax difficulties. I want to set a pointer to point to a variable like this (CTREEITEM is HTREEITEM* , and GetSelectedItem() returns a HTREEITEM) : Code Snippet CTREEITEM = &pCtrl->GetSelectedItem(); In the past, I've done something similar: Code Snippet pCtrl = &this->GetTreeCtrl(); That worked as expected, but now I'm getting the compile-time error message "C2102: '&' requires l-value". I'm at a loss as to what to do. Please advise. Tag: Visual C++ General CWinFormsView VC2005 Visual C++

    - File Handler not working Howler72, Read my post above, you need to remove spaces in directory and file name initialization varibles. Your code, char userDirectory [40]= " " ;//<- remove this breakspace. char fileName [40]= " " ;//<- remove this breakspace. char dirAndFile [100]= " " ;//<- remove this breakspace. My code, char userDirectory [MAX_PATH]= "" ; // <- empty string, without a breakspace. char fileName [MAX_PATH]= "" ;// <- empty string, without a breakspace. char dirAndFile [MAX_PATH]= "" ;// <- empty string, without a breakspace. And everything will work greatly. Or almost greatly if you close handle, and check the returning values. :-) Tag: Visual C++ General CWinFormsView VC2005 Visual C++

    - Makefile project linking broken in Visual Studio 2005? In Visual Studio 2003 and earlier, you could make Visual Studio projects link against the output of a makefile project by setting the Output line. In VS2005 this seems to be broken. Is there something you have to do to get this to work One of the projects I have run into has a work around for this issue by making a separate library project with no files in it, that depends on the makefile project. To get the output of the makefile project to link in, it adds the output of the makefile project to the "Additional Dependencies" line in the separate empty library project. Any upstream libraries then need to depend on the empty library project instead of the makefile project. But this means you have to author 2 project files for every external library. Is there a better way to do this in VS2005 Tag: Visual C++ General CWinFormsView VC2005 Visual C++

    - whats problem with this code? msvs2005 Well, the code generators I've worked on (one of them trying to be highly compatible to VC on the ABI level while heavily optimized for performance for their own set of processors) used different intrinsics for compiler-generated initialization. Oc, VC doesn't ship with a stripped down version with just the compiler support code but other compilers do. But that code, also has the additional benefit of signaling required alignment to the codegen, which allows it use just a plain rep stosd without having to account for additional alignment on either side. While VC's optimization isn't really strong at the microlevel it's probably still smart enough to figure out that an inlined rep stosd is a much better choice than calling a plain dumb memset here. I don't quite get your argument about the size of the structure. It certainly is large enough to warrant using a loop-construct and certainly too small for vectorized execution to amortize set up costs. So, in conclusion, I actually believe it does make a difference for a decent codegen (and I'd even bet VC 7.1+ would be good enough here, too). But then, I don't have access to a copy right now. -hg Tag: Visual C++ General CWinFormsView VC2005 Visual C++

    - question about backups and .ncb files I wanted to make some backups from my source but the portable backup device has limited space and copying needs long. In order to save some space I wrote a script which will delete all folders with name Debug or Relesae. I think I don`t need that folders because I can recompile my source. What about .ncb files Them are quite big. I think them have basically just some informations which speed up reloading the project. If I delete them I need more time starting my project the next time, but no informations are lost forever. Is this correct Tag: Visual C++ General CWinFormsView VC2005 Visual C++

    - Reg 64-bit support Hi, I am relatively new to Visual C++ and require your help on this. I have C++ code which is required to run on both 32-bit and 64-bit Windows. Can I use Visual C++ 2.0 to compile the C++ code or I would need Microsoft Visual C++ 2005 to do this The http://en.wikipedia.org/wiki/Visual_C ++ says that Visual Studio 2005 Standard and Professional editions have x64 compiler support .But currently, I have only Visual C++ 2.0 . Can 64-bit compilation work with 2.0 or I necessarily have to go in for Microsoft Visual C++ 2005 Thank you very much in advance! Tag: Visual C++ General CWinFormsView VC2005 Visual C++

    - Draw to screen without using OnPaint() Hi, my (PocketPC) app normally used GAPI but I'm now moving it to DirectX to support WM6. (My app is written in VC++) I have a question: If I wish to clear the screen and draw stuff to it. If I call the below Render function in the OnPaint() function of my dialog everything is fine and dandy: LPDIRECT3DMOBILEDEVICE g_pd3dmDevice = NULL; // My rendering device VOID Render() { if( NULL == g_pd3dmDevice ) return; // Clear the backbuffer to a blue color g_pd3dmDevice->Clear( 0, NULL, D3DMCLEAR_TARGET, D3DMCOLOR_XRGB(0,0,255), 1.0f, 0 ); // Begin the scene if( SUCCEEDED( g_pd3dmDevice->BeginScene() ) ) { // do stuff here blah blah // End the scene g_pd3dmDevice->EndScene(); } // Present the backbuffer contents to the display g_pd3dmDevice->Present( NULL, NULL, NULL, NULL ); } But the problem I'm having is that I have a class that I normally make full screen and then draw stuff in it, like so: m_pFullScreen = new CFullView(); m_pFullScreen ->CreateEx( WS_EX_TOPMOST, AfxRegisterWndClass( CS_HREDRAW | CS_VREDRAW, 0, (HBRUSH)COLOR_WINDOW), _T("Full View"), WS_VISIBLE | WS_POPUP, 0,0, GetSystemMetrics(SM_CXSCREEN), GetSystemMetrics(SM_CYSCREEN), NULL, NULL); Then I had a function in this class called UpdateDisplay() which used to use GXBeginDraw() etc to draw to screen but now I wish to use the code above in the Render function. It does not work (Nothing is drawn to the screen). If the Render function is called from OnPaint then it works but if there is not an OnPaint() function(Which my CFullScreen class does not have as it is not a dialog) then it does not work Does anyone know how to solve my problem Thanks Harry Tag: Visual C++ General CWinFormsView VC2005 Visual C++

    - OpenFileDialog and SaveFileDialog crashes windows application " I am not familiar with .Net and such so I hope someone will help with it if relevant" If you are not familiar with .NET then why bother answering in the first place ShowDialog has a DialogResult as its return type so it cannot possible return an error. All it can do is to throw an exception which does not seem to happen in this case. OFDialog cannot contain uninitialized fields even in a Release build because .NET runtime always initializes fields and variables to default values (0, false, nullptr). "Please, whenever saying something such as " crash ", be more specific" Well, he was quite specific... the application just closes without leaving a trace. This kind of behavior is possible but it's not going to be easy to find out the reason so back to the orginal question: "Builds of my application that crashes does so consistently." And the other builds work consistently In addition do you change code between a build that works and one that does not work or you just rebuild the project And another thing: You say you are using VC2005 but the sample code you have posted is Managed C++, not C++/CLI syntax. That means that you are using /clr:oldSyntax option which is deprecated. If you don't have a lot of code you shoulld upgrade it to C++/CLI syntax and use /clr:pure or /clr:safe.

We are integrating .NET UserControls into MFC using the CWinfFormsView class. It works great except for a few things. The most important issues is TAB navigation and tooltips (running the same usercontrol on a modal WinForm works fine).

TAB navigation seemingly works, but often suddenly stops working at a specific controls (running the same usercontrol on a modal WinForm works fine)
