  • Connect to server in VMWare player while host is not connected to a network

    - by blockcipher
    Hello, I have a linux server VM on my host machine using VMWare player and if I'm on a network, I can connect to the web server on the VM via a web browser. However, I tried to do the same while I was disconnected from a network and I couldn't. The networking is set to Host-only and I did use dhclient/ifconfig to make sure that yes, I did have an IP address assigned to the VM. While I can work around this, the purpose of the VM is to allow us to demo our app from any machine and that machine may not be connected to a network. Thanks.

  • Windows 7 - Explorer fails to load with UAC enabled

    - by mfranklin
    While running an InstallShield based installer, my Windows 7 machine became unresponsive. After forcing a reboot, I can log in to the system, but explorer does not run. I can log in as a different user without issue and when I change modify UAC to its lowest setting, I can log in as the user that was performing the install. However, if I re-enable UAC, I am unable to get explorer to run again on login. I have checked the HKCU\Software\Microsoft\Windows\CurrentVersion\Run and RunOnce, but don't see anything that isn't configured to run in the user that I can successfully log in as. I completed the installation of the software as the "good" user without issue.

  • EU Digital Agenda scores 85/100

    - by trond-arne.undheim
    If the Digital Agenda was a bottle of wine and I were wine critic Robert Parker, I would say the Digital Agenda has "a great bouquet, many good elements, with astringent, dry and puckering mouth feel that will not please everyone, but still displaying some finesse. A somewhat controlled effort with no surprises and a few noticeable flaws in the delivery. Noticeably shorter aftertaste than advertised by the producers. Score: 85/100. Enjoy now". The EU Digital Agenda states that "standards are vital for interoperability" and has a whole chapter on interoperability and standards. With this strong emphasis, there is hope the EU's outdated standardization system finally is headed for reform. It has been 23 years since the legal framework of standardisation was completed by Council Decision 87/95/EEC8 in the Information and Communications Technology (ICT) sector. Standardization is market driven. For several decades the IT industry has been developing standards and specifications in global open standards development organisations (fora/consortia), many of which have transparency procedures and practices far superior to the European Standards Organizations. The Digital Agenda rightly states: "reflecting the rise and growing importance of ICT standards developed by certain global fora and consortia". Some fora/consortia, of course, are distorted, influenced by single vendors, have poor track record, and need constant vigilance, but they are the minority. Therefore, the recognition needs to be accompanied by eligibility criteria focused on openness. Will the EU reform its ICT standardization by the end of 2010? Possibly, and only if DG Enterprise takes on board that Information and Communications Technologies (ICTs) have driven half of the productivity growth in Europe over the past 15 years, a prominent fact in the EU's excellent Digital Competitiveness report 2010 published on Monday 17 May. It is ok to single out the ICT sector. It simply is the most important sector right now as it fuels growth in all other sectors. Let's not wait for the entire standardization package which may take another few years. Europe does not have time. The Digital Agenda is an umbrella strategy with deliveries from a host of actors across the Commission. For instance, the EU promises to issue "guidance on transparent ex-ante disclosure rules for essential intellectual property rights and licensing terms and conditions in the context of standard setting", by 2011 in the Horisontal Guidelines now out for public consultation by DG COMP and to some extent by DG ENTR's standardization policy reform. This is important. The EU will issue procurement guidance as interoperability frameworks are put into practice. This is a joint responsibility of several DGs, and is likely to suffer coordination problems, controversy and delays. We have seen plenty of the latter already and I have commented on the Commission's own interoperability elsewhere, with mixed luck. :( Yesterday, I watched the cartoonesque Korean western film The Good, the Bad and the Weird. In the movie (and I meant in the movie only), a bandit, a thief, and a bounty hunter, all excellent at whatever they do, fight for a treasure map. Whether that is a good analogy for the situation within the Commission, others are better judges of than I. However, as a movie fanatic, I still await the final shoot-out, and, as in the film, the only certainty is that "life is about chasing and being chased". The missed opportunity (in this case not following up the push from Member States to better define open standards based interoperability) is a casualty of the chaos ensued in the European Wild West (and I mean that in the most endearing sense, and my excuses beforehand to actors who possibly justifiably cannot bear being compared to fictional movie characters). Instead of exposing the ongoing fight, the EU opted for the legalistic use of the term "standards" throughout the document. This is a term that--to the EU-- excludes most standards used by the IT industry world wide. So, while it, for a moment, meant "weapon down", it will not lead to lasting peace. The Digital Agenda calls for the Member States to "Implement commitments on interoperability and standards in the Malmö and Granada Declarations by 2013". This is a far cry from the actual Ministerial Declarations which called upon the Commission to help them with this implementation by recognizing and further defining open standards based interoperability. Unless there is more forthcoming from the Commission, the market's judgement will be: you simply fall short. Generally, I think the EU focus now should be "from policy to practice" and the Digital Agenda does indeed stop short of tackling some highly practical issues. There is need for progress beyond the Digital Agenda. Here are some suggestions that would help Europe re-take global leadership on openness, public sector reform, and economic growth: A strong European software strategy centred around open standards based interoperability by 2011. An ambitious new eCommission strategy for 2011-15 focused on migration to open standards by 2015. Aligning the IT portfolio across the Commission into one Digital Agenda DG by 2012. Focusing all best practice exchange in eGovernment on one social networking site, epractice.eu (full disclosure: I had a role in getting that site up and running) Prioritizing public sector needs in global standardization over European standardization by 2014.

  • VSTO - Outlook 2007 How do I show a user property even when it's not present?

    - by Yandros
    I have added user property in a mail folder, let's call it UserProperty01. Some of the folder items have this property, some don't. I need to show in the folder's view if that property is set or not, so I added another property called UserProperty01Present, and I set it to true when I set the original property and false when I deleted it; then I added it to the folder's view. The problem is that the little checkbox appears checked in those mails where the property is set, blank in those where the property was deleted... and nowhere at all in those where the property was never set in the first place. My question is, is there any way to show the blank checkbox when the property is not set? The only alternative I found so far is looking in every mail item and setting it to false when it's not set every time the folder is opened; needless to say, I'm not very happy with this solution. Is there any other way? Thank you for your time.

  • Regex to ensure group match doesn't end with a specific character

    - by AJ
    I'm having trouble coming up with a regular expression to match a particular case. I have a list of tv shows in about 4 formats: Name.Of.Show.S01E01 Name.Of.Show.0101 Name.Of.Show.01x01 Name.Of.Show.101 What I want to match is the show name. My main problem is that my regex matches the name of the show with a preceding '.'. My regex is the following: "^([0-9a-zA-Z\.]+)(S[0-9]{2}E[0-9]{2}|[0-9]{4}|[0-9]{2}x[0-9]{2}|[0-9]{3})" Some Examples: >>> import re >>> SHOW_INFO = re.compile("^([0-9a-zA-Z\.]+)(S[0-9]{2}E[0-9]{2}|[0-9]{4}|[0-9]{2}x[0-9]{2}|[0-9]{3})") >>> match = SHOW_INFO.match("Name.Of.Show.S01E01") >>> match.groups() ('Name.Of.Show.', 'S01E01') >>> match = SHOW_INFO.match("Name.Of.Show.0101") >>> match.groups() ('Name.Of.Show.0', '101') >>> match = SHOW_INFO.match("Name.Of.Show.01x01") >>> match.groups() ('Name.Of.Show.', '01x01') >>> match = SHOW_INFO.match("Name.Of.Show.101") >>> match.groups() ('Name.Of.Show.', '101') So the question is how do I avoid the first group ending with a period? I realize I could simply do: var.strip(".") However, that doesn't handle the case of "Name.Of.Show.0101". Is there a way I could improve the regex to handle that case better? Thanks in advance.

  • What's the deal with char.GetNumericValue?

    - by mgroves
    I was working on Project Euler 40, and was a bit bothered that there was no int.Parse(char). Not a big deal, but I did some asking around and someone suggested char.GetNumericValue. GetNumericValue seems like a very odd method to me: Takes in a char as a parameter and returns...a double? Returns -1.0 if the char is not '0' through '9' So what's the reasoning behind this method, and what purpose does returning a double serve? I even fired up Reflector and looked at InternalGetNumericValue, but it's just like watching Lost: every answer just leads to another question.

  • PHP: Display comma after each element except the last. Using 'for' statement and no 'implode/explode

    - by Jonathan
    hi, so I have this simple for loop to echo an array: for ($i = 0; $i < count($director); $i++) { echo '<a href="person.php?id='.$director[$i]["id"].'">'.$director[$i]["name"].'</a>'; } The problem here is that when more than one element is in the array then I get everything echoed without any space between. I want to separate each element with a comma except the last one. I cant use 'implode' so I'm looking for another solution... Anyone?

  • Objectdatasource always passes 0 and startIndex and pageSize in asp.net 2.0

    - by 101873438432680351218
    I have a DevXpress ASPXGridview, and I am using ObjectDataSource for custom paging. This is my objectDataSource code on aspx page. <asp:ObjectDataSource ID="ObjectDataSource1" runat="server" SelectMethod="GetItems" EnablePaging="true" TypeName="BLL.Item" StartRowIndexParameterName="startIndex" MaximumRowsParameterName="pageSize" SelectCountMethod="GetTotalItems" > <SelectParameters> <asp:ControlParameter ControlID="hfNumber" Name="number" Type="string" /> <asp:ControlParameter ControlID="hfDesc" Name="description" Type="string" /> </SelectParameters> </asp:ObjectDataSource> When I put breakpoints in BLL code, I see that it always executes with startIndex and pageSize as 0. It does pass the other two selectparameters correctly. Also the SelectCountMethod (GetTotalItems) never gets executed.

  • union marshalling issue in C#

    - by senthil
    I have union inside structure and the structure looks like struct tDeviceProperty { DWORD Tag; DWORD Size; union _DP value; }; typedef union _DP { short int i; LONG l; ULONG ul; float flt; double dbl; BOOL b; double at; FILETIME ft; LPSTR lpszA; LPWSTR lpszW; LARGE_INTEGER li; struct tBinary bin; BYTE reserved[40]; } __UDP; struct tBinary { ULONG size; BYTE * bin; }; from the tBinary structure bin has to be converted to tImage (structure is given below) struct tImage { DWORD x; DWORD y; DWORD z; DWORD Resolution; DWORD type; DWORD ID; diccid_t SourceID; const void *buffer; const char *Info; const char *UserImageID; }; to use the same in c# I have done marshaling but not giving proper values when converting the pointer to structure. The C# code is follows, tBinary tBin = new tBinary(); IntPtr tBinbuffer = Marshal.AllocCoTaskMem(Marshal.SizeOf(tBin)); Marshal.StructureToPtr(tBin.bin, tBinbuffer, false); tDeviceProperty tDevice = new tDeviceProperty(); tDevice.bin = tBinbuffer; IntPtr tDevicebuffer = Marshal.AllocCoTaskMem(Marshal.SizeOf(tDevice)); Marshal.StructureToPtr(tDevice.bin, tDevicebuffer, false); Battary tbatt = new Battary(); tbatt.value = tDevicebuffer; IntPtr tbattbuffer = Marshal.AllocCoTaskMem(Marshal.SizeOf(tbatt)); Marshal.StructureToPtr(tbatt.value, tbattbuffer, false); result = GetDeviceProperty(ref tbattbuffer); Battary v = (Battary)Marshal.PtrToStructure(tbattbuffer, typeof(Battary)); tDeviceProperty v2 = (tDeviceProperty)Marshal.PtrToStructure(tDevicebuffer, typeof(tDeviceProperty)); tBinary v3 = (tBinary)Marshal.PtrToStructure(tBinbuffer, typeof(tBinary));

  • SQL Duplicates Issue

    - by jeff
    I have two tables : Product and ProductRateDetail. The parent table is Product. I have duplicate records in the product table which need to be unique. There are entries in the ProductRateDetail table which correspond to duplicate records in the product table. Somehow I need to update the ProductRateDetail table to match the original (older) ID from the Product table and then remove the duplicates from the product table. I would do this manually but there are 100's of records. I.e. something like UPDATE tbl_productRateDetail SET productID = (originalID from tbl_product) then something like DELETE from tbl_product WHERE duplicate ID and only delete the recently added ID data example: (sorry can't work out this formatting thing) select * from dbo.Product where ProductCode = '10003' tbl_product ProductID ProductTypeID ProductDescription ProductCode ProductSize 365 1 BEND DOUBLE FLANGED 10003 80mmX90deg 1354 1 BEND DOUBLE FLANGED 10003 80mmX90deg SELECT * FROM [MSTS2].[dbo].[ProductRateDetail] WHERE ProductID in (365,1354) tbl_productratedetail ProductRateDetailID ProductRateID ProductID UnitRate 365 1 365 16.87 1032 5 365 16.87 2187 10 365 16.87 2689 11 365 16.87 3191 12 365 16.87 7354 21 1354 21.30 7917 22 1354 21.30 8480 23 1354 21.30 9328 25 1354 21.30 9890 26 1354 21.30 10452 27 1354 21.30 Please help!

  • Storing XML in SQL 2005 XMLNS issue

    - by Mike Mengell
    I'm trying to store XML in SQL 2005. I have a very simple table with an Id and a XML column. When the XML contains the attribute xmlns my searching doesn't work. This is my XML; insert into XMLTest (ItemXML) values ( '<MessageType> <ItemId id="ABC" xmlns="ss" /> <Subject>sub</Subject> </MessageType> ') And this is my Query; select itemid, ItemXML.query('(/MessageType/ItemId)') from XMLTest order by ItemId desc If I change the attribute xmlns to anything else my query works. I don't think I know enough about XML to understand what SQL is doing with the namespace. But it must be processing it and storing it differently maybe? Anyone had this issue?

  • How do I stop Opera from caching a page?

    - by nishkarr
    I am trying to get Opera to re-request a page every time instead of just serving it from the cache. I'm sending the 'Cache-control=no-cache' and 'Pragma: no-cache' response headers but it seems as if Opera is just ignoring these headers. It works fine in other browsers - Chrome, IE, Firefox. How do I stop Opera from caching pages? What I want to be able to do is have Opera re-request a page when the user clicks the Back button on the browser.

  • Who Knows AppWeb HTTP Server And It's Embedded PHP?

    - by Andi
    Hi all, on my search for a fast but comfortable web server I dropped into the homepage of EmbedThis(TM) AppWeb(TM) HTTP server. This one has 2 licencse models, GPLv2 and a commercial one with support. On the first view it looks good: the footprint is not too big, it is fast and it has a lot of configuration otions. The most important thing would be a fast PHP execution using a built-in PHP library. Unfortunately this PHP library doesn't include every option, especially "gettext" which one I need for I18N. My target platform is Linux on an embedded device with an ARM based CPU. Does anybody have experiences with the issues mentioned above? Kind regards, Andi
