  • new operator in DllMain of MFC Extension Dll

    - by Picaro De Vosio
    Hi, Dll best practices document from Microsoft available Here recommends avoiding use of memory management function from the dynamic C Run-Time (CRT) within DllMain. But DllMain function of MFC Extension DLL is dynamically allocating the memory for CDynLinkLibrary in the code snippet available at MSDN "http://msdn.microsoft.com/en-us/library/1btd5ea3%28v=VS.80%29.aspx". Is it a violation of Dll Best Practices or ok to use in MFC extension DLL? thanks

  • ASP.NET - What happens when a HttpCookie expiration has been crossed

    - by user70192
    Hello, I am creating some cookies in my ASP.NET application. These cookies expire 10 minutes after they have been created. I follow the approach described on MSDN as shown here: http://msdn.microsoft.com/en-us/library/system.web.httpcookie.expires.aspx My question is, when a cookie "expires", what happens? Does the browser automatically delete the cookie? Is it our responsibility as developers to remove the cookies if they exist and have expired? Thank you,

  • compact framework windows CE using ExtEscape to control the brightness

    - by mack369
    I need to be able to control brightness of my Windows CE 5.0 device. I've found that there is an API function ExtEscape to do that ( http://msdn.microsoft.com/en-us/library/aa453063 ) but it needs a structure ContrastCmdInputParm (http://msdn.microsoft.com/en-us/library/Aa447689 ) as a parameter. Since ExtEscape is unmanaged, I cannot pass a .net structure. What is the simplest way to call this function?

  • How to sign XML document or verify XML document signature with C++?

    - by Budda
    Subj. I need to sign/verify in native C++ (no .NET), using private key for signing, public key for verification. I saw few examples on MSDN (http://msdn.microsoft.com/en-us/library/ms761363(VS.85).aspx) that demonstrate how to sign the document with CSP (I don't know what this means). For my case I need to create a "key" from the binary data array... can somebody help me with that? Thank you in advance.

  • How to use the ListView_GetBkImage macro in C#

    - by MusiGenesis
    How can I use the ListView_GetBkImage macro: http://msdn.microsoft.com/en-us/library/bb761246(v=VS.85).aspx ... from a C#/WinForms application? I think this macro just wraps the SendMessage method, but I'm not sure. I couldn't find any C#-based samples on this. Basically I'm trying to get a LVBKIMAGE ( http://msdn.microsoft.com/en-us/library/bb774742(v=VS.85).aspx ) structure that references the Desktop's background bitmap.

  • What is the difference between the Control.Enter and Control.GotFocus events?

    - by jameswelle
    This may be a basic question, but I have to admit I've never truly understood what the difference between the Control.Enter and Control.GotFocus events is. http://msdn.microsoft.com/en-us/library/system.windows.forms.control.enter.aspx http://msdn.microsoft.com/en-us/library/system.windows.forms.control.gotfocus.aspx Is it a differentiation between capturing keyboard or mouse input or something else?

  • How To Read C# API From Java Background

    - by ChloeRadshaw
    I come from a Java background and have been using C# for the last year - So far the API docs I use are at MSDN (http://msdn.microsoft.com/en-us/library/ms132397.aspx). I tend to use the lightweight C# docs. What annoys me about that is that I don't see one page with details of the class, a list of members, a list of methods and properties like I would with a Java API definition. Is this possible?

  • Creating semaphores with unmanaged code in C++

    - by Dororo
    I've been using the MSDN Library to create semaphores, located at: http://msdn.microsoft.com/en-us/library/system.threading.semaphore.aspx However, the examples are using Managed code (requires /clr), and I need to use Unmanaged code because FreeType doesn't like working with Managed code it seems. How would I go about creating 2 simple threads which use a semaphore if I'm using unmanaged code? Many thanks for your help.

  • ConcurrenctBag(Of MyType) Vs List(Of MyType)

    - by Ben
    What is the advantage of using a ConcurrentBag(Of MyType) against just using a List(Of MyType)? The MSDN page on the CB (http://msdn.microsoft.com/en-us/library/dd381779(v=VS.100).aspx) states that ConcurrentBag(Of T) is a thread-safe bag implementation, optimized for scenarios where the same thread will be both producing and consuming data stored in the bag So what is the advantage? I can understand the advantage of the other collection types in the Concurrency namespace, but this one puzzled me. Thanks.

  • Using Message Boxes in Windows 7 style

    - by Meta
    After reading the MSDN article about proper user interface here: http://msdn.microsoft.com/en-us/library/aa974176.aspx I want to modify the message boxes I use in my applications to reflect those guidelines (for example, have the Main Instructions in a larger font, better named Buttons, etc...). My question is, is there an API that allows you to easily build those kind of message boxes (a la user32\MessageBox()), or do you actually have to build your own message boxes which follow the guidelines?

  • Server 2008 R2 - Unable to install any printer drivers

    - by toffitomek
    My problem is exactly this same as described here: Server 2008 R2 - Unable to install any printer drivers Options - google groups I have few Windows 2008 R2 (no SP1) servers in remote offices, mostly in Domain Controller, and many of them have problems installing ANY printer drivers. following errors show up in Event Log when adding printer driver under Print and Document Services/Print Management/Print Services/ /Drivers OR trying any other way to install drivers: EventID 215: Installing printer driver - failed, error code 0x57, HRESULT 0x80070057. See the event user data for context information. EventID 215: Installing printer driver Canon iR C2380/2550 PCL6 failed, error code 0x0, HRESULT 0x80070057. See the event user data for context information. EventID 215: Installing printer driver Canon iR C2380/2550 PCL6 failed, error code 0x490, HRESULT 0x80070057. See the event user data for context information. in this particular server case this is problem with Canon iRC 2380i printer with Canon Generic PCL6 Driver, but it seems to apply to any driver and any printer (tried different drivers, different versions, PCL, postscript, etc) I'm using 64 bit drivers that should be working on this platform. Any help will be appreciated.

  • Group policy waited for the network subsystem

    - by the-wabbit
    In an AD domain with Windows Server 2008 R2 DCs users are complaining about delays in the bootup process of the clients. The group policy log reveals that the client is waiting ~ 20-50 seconds for "the network subsystem": Event 5322, GroupPolicy Group policy waited for 29687 milliseconds for the network subsystem at computer boot. This appears to be domain-specific as machines joining a different domain from the same network do not experience any delays and Event 5322 reports <1000 ms wait times at startup. It happens on virtual and physical machines alike, so it does not look like a hardware- or driver-related issue. Further investigation has shown that the client is taking its time before issuing DHCP requests. In the network traces, I can see IPv6 router solicitations and multicast DNS name registrations as soon as the network driver is loaded and the network connection is reported "up" in the event log (e1cexpress/36). Yet, the DHCPv4 client service seems to take another 15-50 seconds to start (Dhcp-Client/50036), so the IPv4 address remains unconfigured for a while. The DHCP client's messages in the event log are succeeding the service start of the "Sophos Anti-Virus" service (Sophos AV 10.3 package), which I suspect to be the culprit - the DHCP client service dependencies include the TDI Support driver which might be what Sophos is using to intercept network traffic: Network Location Awareness seems to break at startup as a side-effect, I see that off-site DCs are contacted due to what seems like a race condition between the GP client and the DHCP client / NLA service startup. I could set the Group Policy Client service to depend on NLA, yet this still would not eliminate the delay. Also, I am not all that sure that this is a good idea. Is there a known resolution which would eliminate the startup delay?
