• Landon Parks DLGINIT structure

  I want to create the dialog dynamically in memory. The dialog contains some ActiveX controls. According to the description for CDialog::CreateIndirect, I have to provide a DLGINIT resource. But I can't find the details about this structure. Following is a sample of such structure in a .RC file: ///////////////////////////////////////////////////////////////////////////// // // Dialog Info // IDD_XXXDIALOG DLGINIT BEGIN IDC_YYCONTRO1 , 0x37a , 298, 0 init data 1 IDC_YYCONTROL2 , 0x37a, 186, 0 init data 2 0 END I could load the resource and create a dialog. But I can't generate the data on the fly since I don't know the structure, for example, what is the value 0x37a Thanks for any info. ...Show All

• Dots ATL8, depending library's

  Hi, i'm creating a activeX object (ATL8/COM) with Visual studio 2005. I was wondering when at the moment that i publish the client object, do the users need new updated dll's like with the new CRL when running a C++ application written in VC8 because that wouldnt be really effective ;) thanks already Ok thanks, i can live without it :) hardly but still ok but that would take one big advantage away from ATL, filesize. You can link the libraries into your dll. If you compile with VC8 and use the CRT, then yes, it will use the VC8 CRT. VC8 uses the VC8 CRT. All you can do is avoid using the CRT. I try to avoid it any how. ...Show All

• MFZ Application built with VS 2005 SP1 does not run on another computer

  Three executables were delivered from a development machine to a production machine, to which I do not have direct access at this time. One built with VC6 runs without a problem. One built with VC8 SP1 does not run due to an error that looks like vcredist was not installed. One apparently built with VC8 w/o SP1 does run. My questions - 1. How can one check with which version of VC was the 3rd executable was created 2. How can one check whether vcredist for VS8 was installed or not on that machine 3. Anyone knows of a problem with VC8-SP1 built images requiring extras beyond said vcredist TIA, Tzal. "I don't know what vcredist is but it probably is not the recommended solut ...Show All

• polymorphicx Compiler Crash

  OK I know I shouldn't have written it, it was a result of some slow responses on the machine that a class name got replaced by a bracket, and I;ve thrown away a lot of unnecessary stuff however:make a file containing typedef struct {} (; And the compiler will crash. .Net 2005, I haven't tried it on 2003 or Team System.

• mkrtchyan.arsen problem with /NODEFAULTLIB linker option

  Hello, I'm trying to compile a C++ code with /clr option and remove all references to the default library. I want to only analyze the output code and do not need to run it.

• Jon Derbyshire SetWindowsHookEx making all console apps come to a crawl.

  I have a case where my Windows process uses SetWindowsHookEx to inject a WH_KEYBOARD hook in all processes of the desktop. Everything works as expected except in the case of console applications; including cmd. While my process is running, in console applications, typing is very slow almost like there is a delay in each keyboard event. This is the case even if I have my KeyboardProc does nothing except call CallNextHookEx. All Windows processes are unaffected; it's only console apps. I debugged cmd and found that my DLL never gets loaded in the cmd process, which I would expect since console apps shouldn't bind to User32. I know of other hooks on my computer from other installed software that don’t have the same effect as my hook. A ...Show All
