  • ComDlg32.ocx Error: Object doesn't support this property or method

    - by abhilashca
    I'm developing an html editor using ComDlg32.ocx (Commom Dialog Control), using HTML and VBScript. My exact requirement was to prompt Open/Save/Color/Print/Font dialog boxes.Ive written code for prompting Save file dialog box. Also I've added a license file using LPK Tool onto my webpage. My html-source looks like: <body> <!-- lpk file --> <object classid="clsid:5220cb21-c88d-11cf-b347-00aa00a28331"> <param name="LPKPath" value="License/comdlg.lpk" /> </object> <!-- Microsoft Common Dialog Control --> <object classid="CLSID:F9043C85-F6F2-101A-A3C9-08002B2F49FB" codebase="http://activex.microsoft.com/controls/vb6/COMDLG32.CAB" id="objComDlg"></object> </body> Now, here comes my error. Whenever I try to call the vbscript for prompting the Save File dialog box, Im getting an error as : Object doesn't support this property or method: 'objComDlg.Filter' If I comment out the objComDlg.Filter then the error move on to objComDlg.DialogTitle and thus it goes on. And my VBScript look like: FILE_FORMATS = "Rich Text Format (*.rtf)|*.rtf|Microsoft Word (*.doc)|*.doc|ANSI Text Document (*.txt)|*.txt" objComDlg.Filter = FILE_FORMATS <--- Error shows here objComDlg.DialogTitle = "Save As " objComDlg.Flags = cdlOFNFileMustExist Or cdlOFNHideReadOnly objComDlg.CancelError = True objComDlg.ShowSave Does anyone have an idea why this is happening? Is there any proper documentation for using this particular ActiveX control? My current development is in stand-still due to this error. Any help will be appreciated. Looking forward for your response. BTW, I'm using Windows XP SP3 and IE8 for my development. Thanks.

  • Update BIOS on Sun Fire X4150 server

    - by Massimo
    I have some Sun Fire X4150 servers with a very old BIOS release (1ADQW015), which seems to have some compatibility problems with WMware ESX Server 3.5 and Windows 2008 R2 virtual machines; so I want to update the BIOS on them. The problem: according to this page, if your servers run ELOM (mine do), you first need to update to the latest ELOM release, then to the interim transition release, then finally you can update to the latest one. Ok, I'm willing to do that... but it looks like Sun (now Oracle) will happily let you download the latest firmware DVD (3.3.0), but it will not let you download the transition release (2.0) if you don't have a support contract. Well, I actuall don't care at all about the servers' management controllers (we don't even use them), so upgrading from ELOM to ILOM is totally irrelevant to me; but I need to update the servers' BIOS. So my question is: can I update the servers' BIOS to the latest version without doing the full ELOM-to-ILOM migration, or will this not work (or even make the servers unusable)? Do BIOS versions and SP ones need to be matched, or can one be updated without bothering with the other? Bonus question: if this whole ELOM-to-ILOM thing actually is needed in order to update the BIOS, can that 2.0 CD-ROM be obtained without having a support contract with Sun/Oracle (which we are definitely not going to sign, being that quite old hardware)? Update: I tried upgrading only the BIOS on one of the servers, and it didn't boot anymore. So it really looks like a full firmware upgrade is needed, and the management controller and BIOS versions should be kept in sync. So... where can I find that *&!£%$% 2.0 CD-ROM? Or at least the transition firmware that can be found on it?

  • When should I be cautious using data binding in .NET?

    - by Ben McCormack
    I just started working on a small team of .NET programmers about a month ago and recently got in a discussion with our team lead regarding why we don't use databinding at all in our code. Every time we work with a data grid, we iterate through a data table and populate the grid row by row; the code usually looks something like this: Dim dt as DataTable = FuncLib.GetData("spGetTheData ...") Dim i As Integer For i = 0 To dt.Rows.Length - 1 '(not sure why we do not use a for each here)' gridRow = grid.Rows.Add() gridRow(constantProductID).Value = dt("ProductID").Value gridRow(constantProductDesc).Value = dt("ProductDescription").Value Next '(I am probably missing something in the code, but that is basically it)' Our team lead was saying that he got burned using data binding when working with Sheridan Grid controls, VB6, and ADO recordsets back in the nineties. He's not sure what the exact problem was, but he remembers that binding didn't work as expected and caused him some major problems. Since then, they haven't trusted data binding and load the data for all their controls by hand. The reason the conversation even came up was because I found data binding to be very simple and really liked separating the data presentation (in this case, the data grid) from the in-memory data source (in this case, the data table). "Loading" the data row by row into the grid seemed to break this distinction. I also observed that with the advent of XAML in WPF and Silverlight, data-binding seems like a must-have in order to be able to cleanly wire up a designer's XAML code with your data. When should I be cautious of using data-binding in .NET?

  • What is a good programming language/environment for Linux database applications?

    - by Dkellygb
    I could use some advice on my move from the Windows world to Linux. For my business, I have used VB6 and Microsoft Access with both Access databases and SQL server in the past. The easy to use forms, report writers and programming language were perfect for CRUD apps and analysis for our small hotel/restaurant business. After using Linux at home for some time I would like to convert our small business. Our server is already a Linux box using Samba. I am happy with the OpenOffice.org applications instead of Microsoft Office. The only thing which is holding me back is a desktop database application where I can develop the forms and reports we require. Base does not seem to be up to the job yet from my experience. I would like something like VB.Net with visual studio (express) but I would like to avoid Mono – I just don’t see the point of it. (You can correct me if I’m wrong.) But a good collection of forms, controls and a good report writer would be ideal. I have looked at web based stuff like Ruby on Rails, but I think a webserver for our 5 pc network is overkill. I don’t mind running a proper database on our Ubuntu 9.10 server. I may have exposed a few prejudices above but my mind is open. Any thoughts?

  • DAS vs SAN storage for serving 2 to 4 nodes

    - by Luke404
    We currently have 4 Linux nodes with local storage, arranged in two active/passive pairs with storage mirrored using DRBD, running virtual machines (actually using Xen Hypervisor) for typical hosting workloads (mail, web, a couple VPS, etc.). We're approaching the (presumed) maximum IOPS of those servers, and we're planning to migrate to an external storage solution with two active nodes, with capacity for up to four active nodes. Since we're an all-Dell shop I've done some research and found the MD3200 / MD3200i products should be the ones we're looking for. We are pretty sure we won't be attaching more than 4 hosts on a single storage and I'm wondering if there is any clear advantage for one or the other. In theory I should be able to attach 4 SAS hosts to a single MD3200 (single links on a single controller MD3200, or dual redundant SAS links from each host to a dual-controller MD3200), or 4 iSCSI hosts to a single MD3200i (directly on its 4 GigE ports without any switch, again with dual links for the dual controller option). Both setups should let us implement live VM migration since all hosts can access all the LUNs at the same time, and also some shared filesystem like GFS2 or OCFS2. Also, both setups should allow full redundancy of the whole system (assuming dual controllers in the storage). One difference I can see is that the DAS solution is actually limited to 4 hosts while the iSCSI one should be able to grow to more hosts (adding two GigE switches to the mix). One point for the iSCSI solution is that it would allow us to start out with our current nodes and upgrade them at a later time (we can't add other SAS controllers, but they already have 4 GigE ports each). With the right (iSCSI|SAS) controllers I should be able to connect diskless nodes and boot them off the external storage which I think is a good thing (get rid of any local storage). On the other hand, I would have thought the SAS one to be cheaper but it seems like an MD3200 actually costs a little less than an MD3200i (?) (please note: I've used Dell gear in my examples since that's what we're looking for but I assume the same goes with other vendors) I would like to know if my assumptions above are correct, and if I'm missing any important difference between the two setups.

  • Hiring my first employee

    - by Ady
    A few years ago I moved to a new job having been programming for 2 years using C#, however this new company was mainly using VB6. I made the case for .NET and won, but one of the consessions I had to make was to use VB.NET and not C# (understandable as most of the other developers were already using VB). Three years later it was time to move on, but when applying for jobs I couldn't get past the recruitment agents. I realised that when they were looking at the basic requirements (5 years experience) that they could not add 2 and 3 together to make 5. They were looking for 5 years in VB or C# not across both. Frustrated I decided to combine my skills with a designer friend and start my own company. After two years of hard graft we are now looking for our first employee (a programmer), and this question has hit me again, but now I see the employers perspective. Why take the risk of someone getting up to speed when you have thousands of applicants to choose from. So my question is this, if I define the requirements to be too narrow, I could miss the really great candidates. But if they are too broad it's going to take ages to go through them all. This will be our first 'employee' so the choice needs to be good, I can't afford to make a mistake and employ someone naff. Another option would be to choose a bright university graduate, and train them up (less of a risk because we can pay them less). What have others done in this situation, and what would you recommend I do?

  • How to provide js-ctypes in a spidermonkey embedding?

    - by Triston J. Taylor
    Summary I have looked over the code the SpiderMonkey 'shell' application uses to create the ctypes JavaScript object, but I'm a less-than novice C programmer. Due to the varying levels of insanity emitted by modern build systems, I can't seem to track down the code or command that actually links a program with the desired functionality. method.madness This js-ctypes implementation by The Mozilla Devs is an awesome addition. Since its conception, scripting has been primarily used to exert control over more rigorous and robust applications. The advent of js-ctypes to the SpiderMonkey project, enables JavaScript to stand up and be counted as a full fledged object oriented rapid application development language flying high above 'the bar' set by various venerable application development languages such as Microsoft's VB6. Shall we begin? I built SpiderMonkey with this config: ./configure --enable-ctypes --with-system-nspr followed by successful execution of: make && make install The js shell works fine and a global ctypes javascript object was verified operational in that shell. Working with code taken from the first source listing at How to embed the JavaScript Engine -MDN, I made an attempt to instantiate the JavaScript ctypes object by inserting the following code at line 66: /* Populate the global object with the ctypes object. */ if (!JS_InitCTypesClass(cx, global)) return NULL; /* I compiled with: g++ $(./js-config --cflags --libs) hello.cpp -o hello It compiles with a few warnings: hello.cpp: In function ‘int main(int, const char**)’: hello.cpp:69:16: warning: converting to non-pointer type ‘int’ from NULL [-Wconversion-null] hello.cpp:80:20: warning: deprecated conversion from string constant to ‘char*’ [-Wwrite-strings] hello.cpp:89:17: warning: NULL used in arithmetic [-Wpointer-arith] But when you run the application: ./hello: symbol lookup error: ./hello: undefined symbol: JS_InitCTypesClass Moreover JS_InitCTypesClass is declared extern in 'dist/include/jsapi.h', but the function resides in 'ctypes/CTypes.cpp' which includes its own header 'CTypes.h' and is compiled at some point by some command during 'make' to yeild './CTypes.o'. As I stated earlier, I am less than a novice with the C code, and I really have no idea what to do here. Please give or give direction to a generic example of making the js-ctypes object functional in an embedding.

  • Practical refactoring using unit tests

    - by awhite
    Having just read the first four chapters of Refactoring: Improving the Design of Existing Code, I embarked on my first refactoring and almost immediately came to a roadblock. It stems from the requirement that before you begin refactoring, you should put unit tests around the legacy code. That allows you to be sure your refactoring didn't change what the original code did (only how it did it). So my first question is this: how do I unit-test a method in legacy code? How can I put a unit test around a 500 line (if I'm lucky) method that doesn't do just one task? It seems to me that I would have to refactor my legacy code just to make it unit-testable. Does anyone have any experience refactoring using unit tests? And, if so, do you have any practical examples you can share with me? My second question is somewhat hard to explain. Here's an example: I want to refactor a legacy method that populates an object from a database record. Wouldn't I have to write a unit test that compares an object retrieved using the old method, with an object retrieved using my refactored method? Otherwise, how would I know that my refactored method produces the same results as the old method? If that is true, then how long do I leave the old deprecated method in the source code? Do I just whack it after I test a few different records? Or, do I need to keep it around for a while in case I encounter a bug in my refactored code? Lastly, since a couple people have asked...the legacy code was originally written in VB6 and then ported to VB.NET with minimal architecture changes.

  • is there a Universal Model for languages?

    - by Smandoli
    Many programming languages share generic and even fairly universal features. For example, if you compared Java, VB6, .NET, PHP, Python, then you would find common functions such as control structures, numeric and string manipulation, etc. What has been done to define these features at a meta-language (or language-agnostic) level? UML offers a descriptive reference of software in every aspect, but the real-world focus seems to be data processes. Is UML relevant? I'm not asking "Why we don't have a single language that replaces the current plethora." We need many different tools (at least in this eon). I'm not asking that all languages fit a template -- assembly vs. compiled languages are different enough to make that unfeasible (and some folks call HTML a language, though I wouldn't). Any attempt would start with a properly narrow scope. In line with this, I wouldn't expect the model to cover even a small selection with full validity. I would expect however that such a model could be used to transpose from one language to another (with limited goals -- think jist translation).

  • Why do you use a 3PAR SAN? [closed]

    - by Starfish
    If you use a 3PAR SAN, I’d like to hear what you think about it, particularly compared to the HP EVA. What do you see as its advantages over other SANs like the EVA? What’s so special about the ASIC? We had HP quote us an EVA P6500 and 3PAR V400 with equivalent storage and the 3PAR was nearly twice the cost. My site has two EVA SANs with a combined capacity of ~80 TB. We want to replace the older and larger of the two. We’ve been looking at the EVA and the 3PAR to see which would be a better fit for us. I’m struggling to understand how the 3PAR differs from the EVA from a practical technical standpoint. When I read the sales literature and speak with the HP sales engineers, they spend a lot of time talking about how the 3PAR is better because of its ASIC. It’s ASIC this and ASIC that, but when I press them on how a 3PAR with thin provisioning is better than an EVA with thin provisioning, I can’t get a straight answer. Meanwhile, one of my colleagues, who has more say regarding which SAN we get, is enamored by the 3PAR, and he can’t explain clearly to me why he wants it over the EVA. Our needs are pretty simple. We have 10 servers running VMware and ~100 VMs. We use VMware’s thin provisioning currently, but we would like to start using thin provisioning on the new SAN. We don’t have a need for SSDs or migration between storage tiers. We plan on having FC or SAS drives for our most used data and SATA/FATA drives for the lesser used data which is how we have the EVAs configured. We also do not need any SAN-level snapshotting or replication.

  • Using SetParent to steal the main window of another process but keeping the message loops separate

    - by insta
    Background: My coworker and I are maintaining a million-line legacy application we inherited. Its frontend is written in VB6, and as we're devoting almost all of our resources to converting it to C#, we are looking for quick & dirty solutions to our specific problem. The application behaves in a plugin-ish manner. There are up to 20ish separate ActiveX controls that can be loaded at once in a grid-style layout. The problem is that the ActiveX controls do all of their processing on their own UI thread, and as a lot of it is blocking waiting on network access, the UI gets very soupy. When our hosting C# app loads these controls, it becomes unresponsive because of how many controls are chewing up UI resources doing nothing. To top it off, the controls are fragile and will crash at the slightest provocation. When they are hosted in the main C# app, it creates serious instability. The best my coworker and I have come up with so far is starting a process per ActiveX control. This process, which we call the proxy, is another winforms app. It uses named pipes to communicate with the hosting process. The hosting process creates a window, loads an ActiveX control of our choice (via some reflections & AxHost magic), and tells the main process what its window handle is via the named pipe. The main process uses a combination of SetParent, and SetWindowPos to move the proxy application into itself to emulate a plugin. Size updates are sent via the named pipe. This works well enough until the ActiveX application does some sort of lengthy process and we click around on the main window while it's working. For awhile the main window is responsive, but eventually it becomes unresponsive as the child window waits for its UI thread. How can we keep the child windows on their own complete thread while still getting the benefits of SetParent? (please let me know if anything isn't clear!)

  • Technology Plan - Which tools should I use?

    - by Armadillo
    Hi, Soon, I'll start my own software company. My primary product/solution will be a Billing/Invoice Software. In a near future, I pretend to expand this first module to an ERP. My app should be able to run as a stand-alone application and as a Web-based application (so there will be, probably two GUI for the same Database). My problem, now, is to choose the right tools; I'm talking about what programming language(s) should I use, what kind of database should I choose, and stuff like that. I'm primarily a VB6 programmer, so probably I'll choose the .net framework (vb/c#). But I'm seriously thinking about Java. Java has 2 "pros" that I really like: write once, run anywhere and it is free (I think...). I've been thinking about RIAs too, but I just don't have any substantial feedback about them... Then, I'll need a report tool. Crystal Reports? HTML based Reports? Other? Databases: I'm not sure if I should use SQL-Server Express or PostgreSQL (or other). I'd be happy to hear any comments and advices Thanks

  • What should a self-taught programmer with no degree learn/read?

    - by sjbotha
    I am a self-taught programmer and I do do not have any degrees. I started pretty young and I've got about 7 years of actual programming work experience. I believe I'm a pretty good programmer, but I admit that I have not played much with algorithms or delved into any really low-level aspects of programming such as how compilers work. I have worked with other programmers with and without degrees. Some were good and some not; having a degree didn't seem to make any difference as to which pot they fell into. Since then I've come to realize that it does depend on the school where the degree is obtained. Some people suggest that you really should get a degree; that there are things you'll learn in the process that you won't learn in the real world. Of course there is personal growth and discipline learned from completing a task of that magnitude, but let's just concentrate on the technical knowledge. What would I have been taught in a GOOD CS course that would aid me today and what can I read to fill the gap? I've heard the book "Algorithms" mentioned and I plan on reading that. What other books would you recommend? Edit: Clarification on 'actual work experience': Have worked for 2 small companies on teams with fewer than 5 people. About 2 years experience with Perl, Python, PHP, C, C++. About 5 years experience in Java, Applets, RMI, T-SQL, PL/SQL, VB6. 7 years experience in HTML, Javascript, bash, SQL. Most recently in Java designed and helped build an N-tier Java app with web frontend and RMI.

  • How To Replace Laptop HDD Without Losing Data?

    - by Ishan
    Hello, I recently went to Dell Service center and they tell that HDD is faulty and needs to be replaced. I have a Studio 1457 laptop with 500 GB HDD and don't want to lose the data(purchased in May 2010, still under warranty). I have searched a bit and I think it may be best to use a disk imaging software for this task. However, I don't know about a good software. I have following steps in mind: Get a 1 TB External HDD. Make an image of existing 500 GB HDD and store data on external disk. Install new HDD and install a brand new Windows copy and then install the software on it. Using the same software I used to make image, restore the old HDD image on new one. However, I have some questions in mind. First, is this possible? Second, I live in a country where piracy is a big issue and I am sure the support executive who will come to change HDD will have a pirated copy. But I have genuine Windows 7 Pro and don't want to lose it. Now, Dell does not supply and OS disks, so I can't install it on new HDD! If I follow above steps, which version of Windows 7 will be retained? One in the image(authentic) or one in the new HDD(pirated). I am ready to purchase a good software for this task and my budget is $50-60. Since laptop is under warranty, new HDD will be free. One last thing, I have created a Windows Migration file whose size is 70 GB. Can it be used to move from Windows 7 Pro to Windows 7 Pro?(In case I get a genuine copy of Windows 7!) Any other method to save all the data? Thanks in advance.

  • Webforms vs. MVC. Once you start using MVC.. Do you ever go back to webforms?

    - by punkouter
    I checked out MVC months ago and didn't really get it.. but recently as I have become a better programmer I think it is making sense.. Here is my theory.. tell me if I got it Right In the 90s for Microsoft Devs we had Classic ASP. This mixed VBscript and HTML on the same page. So you needed to create all the HTML yourself and mix HTML and VBScript. This was not considered Ideal. Then .NET came along and everyone liked it because it was similiar to event driven VB 6 style programming. It created this abstraction of binding data to ASP Servier controls. It made getting Enumerated data easy to get on the screen with one line. Then recently Jquery and SOA concepts are mixed together.. Now people think.. Why create this extra layer of abstraction when I can just directly use .NET as a data provider and use jquery AJAX calls to get the data and create the HTML with it directly .. no need for the Webforms abstraction layer.. Sowe are back to creating HTML directly like we did in 1999. So MVC is all about saying Stop pretending like WEb programming is a VB6 app! Generate HTML directly! Am I missing anything? So I wonder.. for you people out there using MVC... is it the sort of things that once you get used to it you never want to go back to webforms??

  • Advice on using .Net WorkFlow State Machine. What would you do?

    - by jlafay
    So I've been tasked at work to write windows services to replace some old legacy VB6 WinForms apps currently running as services, consistently repeating tasks day-to-day. To give some general background, they have there own state machines built in to handle decision basing and not utilizing threading. A lot of the senior developers here thought it would be worth a try to look into WorkFlow to replace the state machines rather than write my own business logic and try threading it programmaticly. So it's WF vs. the "Old College Try" I suppose. My concern is that there aren't many books on the topic, and since it was implemented in .Net I've heard very little about it being used. I brought this up at work and another developer mentioned that it's because Biz Talk never really caught on and it was designed for that. So is it broken? Do you think it will be supported long enough to not worry so much? I don't want an ill-functioning process injected into my services, my new babies at work, and then have WF's keel over. Leaving me with having to replace them with my own code in the event of an emergency; which does not seem like much of a grand scenario to me. Any suggestions, recommendations would be super.

  • Skip new Windows 7 user selection and go to login prompt

    - by Doltknuckle
    We've begun our migration to windows 7 and we ran into an interesting issue. When we hit "CTRL+ALT+DEL" we are brought to the "User selection Screen". Normally, this screen will have an icon for every local user for the machine. These machines are Domain members with "Fast User Switch" disabled so no user names are listed only the "Other User" option. If you click "Other User" or hit enter, the system moves on to the normal login screen where it prompts for user name and password. Here's the issue: We want to find a way to skip over the part where a user selects "Other User". We essentially want the system to always assume that we always want "Other User" and to go directly to the login screen when a user hits "CTRL+ALT+DEL". What I find odd is that the "Other User" doesn't show up until we've had more than one domain user log in. Right after we re-image the machine, the login process goes directly to the user credential prompt. Anyone have any ideas?

  • Is Ubuntu a viable replacement of Windows XP for small enterprise environments?

    - by Alex. S.
    Hi all, I'm a newbie systems administrator, so any advice would be great. I would like to setup ubuntu 8.04 lts in a small office of consulting in management (around 50 workstations) instead of Windows XP. I would install MS Office 2007 via WINE (*). It would be a fresh installation, so the migration would be less of a pain. The new setup would also include a small server as document repository and a backup server by now. Later, I would install another goodies like a IM server, a document management solution, and whatnot collaborative tool. What do you advice in this scenario? Do you think is viable? Should I try to convince my managers this is a good idea? I consider myself as a fair experienced user in both systems, and I'm the only guy in charge of everything. I need to cut costs down, and I think that antivirus and antimalware software are a waste of money and time. Is this good idea?, or should I resign and try to lock down the Windows systems and install AV software? Is there anything else in this setup I'm not foreseeing? (*) The only catch in my test machine until now had been that Office SmartArt doesn't work properly, the rest of Office 2007 may seem ok.

  • Generalized strategy for file server virtualization in Xenserver

    - by Jamie
    I'm not shopping as much as I'm looking for some guidance on good idea / bad idea strategies. I'm sure I'm not in the "best practices" budget range. Currently, I have 3 dell poweredges running xenserver in a pool. Each node has a ubuntu file server, serving about 6TB. One is the primary, the other two are rsync targets for backup. The 6TB is stored on their respective local storage disks as an LVM of 3x2tb virtual disks. The fileserver VM disks are also stored on the node local disks. Each node also runs a smattering of light-weight VMs for web, development, windows VMs, and stuff like that. Several of those VM's disks reside on a QNAP NAS to play with live migration. These VM's are often clients of the primary file server (like all the mail, web content, user files are stored on the file server, not on the mail, web, and samba VMs). This all works fine, and is a major step up for us. The downside is that the QNAP is a single point of failure. And the only thing the QNAP is doing is serving migratable VM images, not client data. Someday the poweredge local arrays will be full, and we will have to reinvent ourselves again. Is it wise to have heavywieght vms (like the fileserver, with its 6+ TB disks) on a SAN or NAS? Would it be better to keep the VMs lightweight, have the VM images on a SAN or NAS, and use 2 or more NAS act as NFS-serving file appliances? A hybrid SAN/NAS that can serve iscsi for images and NFS for the client vms? It seems like live-magration would be a misnomer if you have to migrate a fileserver with its entire 6+ TB disk. I recognize there are plenty of ways to skin the cat. We've already skinned it a few ways. What makes sense?

  • Virtualize SBS 2003 - P2V vs migrating to new VM

    - by jlehtinen
    I need to virtualize a SBS 2003 server in my work environment. I need some tips on what people think is the best way to proceed. Background: The SBS 2003 server is the primary DC for the domain and also hosts FTP, RRAS(VPN), DNS, and file shares. Exchange is NOT used, neither is SQL server. DHCP is done via a firewall appliance. I have added a Server 2003 VM to the domain and promoted it to the DC role. AD/DNS is replicating here correctly. This was mainly done to provide fault-tolerance to the domain, I was not intending to make this VM the primary DC. I've already asked about buying upgraded licensing for Server 2008/2012 but was refused due to cost. Options: I see (at least) two routes I could take to complete this. From what I've read option 2 is the "preferred" method, but there's a few steps where I'm not clear on what to expect. Option 1.) P2V the primary DC Power off primary DC Power off secondary DC (to prevent USN rollback in case P2V has issue) P2V (cold clone) primary DC Boot new PDC VM Allow new hardware to detect Remove old NIC hardware from device manager Assign old IPs to new virtual NICs Reboot PDC VM, confirm connectivity and no major issues Power on secondary DC, confirm replication Option 2.) Create new VM, transfer roles, remove original DC from domain Create new VM, install SBS 2003 Do I need the original SBS install discs for this? MS migration doc mentions this. Add VM to domain, promote to DC role Does this start 7 day timer where two SBS servers can be in same domain? Set up RRAS on new VM Set up IIS/FTP on new VM Move file shares to new VM Transfer FSMO roles to new VM DC dcpromo original primary DC out of domain

  • Migrate Maildir between courier and dovecot servers

    - by DeaconDesperado
    I have several tarballs that make up all the previous emails for two or three accounts on a mail server. This machine we be shut down within a few weeks and so I need to migrate all the previously subscribed IMAP folders to the new server. The old machine ran Dovecot with exim and delivered all mail to a virtual user folder on the server in maildir format. The new machine uses courier and postfix, also configured to deliver through maildir. The new server is already setup and all clients are successfully logging in, the problem is migrating their old conversations. I've tried moving the old message files directly and deleting the imap db that records which messages have already been fetched, but nothing has been successful. The outlook clients present an error for every message saying that the "message can no longer be located on the server." Keeping the files chronologically sorted is not an object, I just need to migrate the old conversations over. Is there a way to do this in a batch operation that will allow the clients to login to the new server and treat these old messages as though they were new? What is the protocol for this kind of migration?

  • What issues might I have in opening .NET 2.0 Projects in Visual Studio 2010?

    - by Ben McCormack
    The small software team I work on recently got approved to upgrade to Visual Studio 2010 (we're currently using VS 2005). We have several ASP.NET 2.0 and WinForms (in .NET 2.0) projects in production. I've been tasked with downloading VS 2010 and seeing how well it plays with our current projects. What issues should I be aware of when targeting older applications in VS 2010? If I open a VS 2005 project in VS 2010, will it still place nicely when my teammate goes back to open the project in VS 2005? Will we have to upgrade projects to work in VS 2010 (assuming the projects themselves aren't upgraded to .NET 4)? Can I use VS 2010 to edit legacy VB6 apps (just kidding)? I'm excited to work with the newest software, but we're concerned about running into development snags on production applications that are already working just fine. NOTE: I started a bounty in hopes of getting a more detailed answer to this question. Perhaps the answer really is as simple as those already provided, but I'm interested in more feedback regarding our options to transition from using VS 2005 to VS 2010.

  • Does migrating 2 domain controllers between 2 datacentre requires both virtual machines to be shut down at the same time?

    - by Imagineer
    I was attempting to migrate 2 virtual machines that are domain controllers between 2 datacentres running ESX 3.5 and ESX 4.1. I was advised to shut down both domain controller at the same time during the migration process. This is to avoid USN Rollback and other replication issues. The following are the steps that I was planning to perform: 1. Shutdown both DC. 2. Copy both VMs files across to new datacentre using Veeam FastSCP (connection to both vCentre through IP address instead of hostname) 3. Power them up at new datacentre. 4. Configure Network interface/DNS/DHCP for both DCs in new datacentre I have tried to use Veeam FastSCP rather than VMware Standalone Converter is because its copying rather than converting. Someone also suggested that I use backup and restore app like Veeam backup and replication software. Sounds like a simple job, but after shutting down both DCs, the transfer rate using FastSCP is so slow registering only 1KB/s as oppose to the normal 1MB/s (or more). When that attempt to transfer failed, I tried to cold clone both DCs resulted in the both ESX hosts get disconnected. I have tried troubleshooting by referring to this - VMware KB - Diagnosing an ESX Server that is Disconnected or Not Responding in VirtualCenter It seems that the DNS being down is the caused of all unusual occurrence. The moment I powered up the DCs via VMware console command, the ESX host were able to connect to the vCentre again. How can I avoid such a pitfall again? Am I doing it correctly? Any help would be greatly appreciated! Thank you.

  • Using rsync to migrate files between windows servers: problems with Excel spreadsheets

    - by HorusKol
    We've been migrating about 220 GB of data from a Windows 2003 Server to a Windows 2008 Server, and because of the time it would take to copy that data and the necessity of keeping it available for users, I came up with the idea of using rsync on an Ubuntu server to broker the migration. (I might have gone for a proper Windows solution - but the applications I found were a bit pricey for a one-shot like this - and permissions are not a problem). All well and good - and today I'm making the last sync and confirming that the new server is up-to-date using diff, but I"ve noticed an odd thing with Excel spreadsheets (.xls). Every instance of an Excel spreadsheet that has already been copied in a previous in a previous synchronisation is being marked as "already up-to-date" by rsync. However, when I then run a diff, I'm told that the files differ. I'm manually copying them, as there are but a handful, but I was wondering what might be causing this. No other filetype in the entire 220 GB tree has had any problem like this - just the Excel/xls files. It'd be great if someone could come up with an explanation.

  • Migrating JBoss installation and install it on a PHP server

    - by David Martinez
    I'm configuring a new dedicated server that is going to run 3 sites, 2 of then are migrating from a old server. Each site have it's own domain and dedicated ip. 2 of this sites are already up and running on php (one of then use cakePHP), the third site is a migration from an old server and it runs on JBoss. 1) Is it possible to have both Jboss and php running on the same Apache instance, or would I have to install a new one? 2) Can I just move the old JBoss server directory to the new server and start the server with the shell script? From what I red here JBoss is distributed as a zip/tgz file with the server structure, so moving it from the old server to the new one should be the same. I want to do this because the old server is already configured, and it have 2 JBoss instances. I didn't develop this site and I don't have experience with JBoss. I have some documentation of the site, but it is not much, mostly server structure and the technology they used. The new server runs on CentOS with CPanel, I have full root access to the server. This question is similar to this one How can I run JBoss Application Server and Apache on the same server? but there he didn't have a dedicated IP for each domain.
