I have a question about deploying application, my application need gdiplus.dll for load images.
Does windows xp contain GdiPlus.dll as default?
Many Thanks!
I don't think it is a guarantee, but in my experience it has almost always been there already. There is a GDI+ redistributable:
Edit: Here they state quite plainly that GDI+ "is included in Windows XP". So unless you are deploying to one of those other operating systems, it sounds like you can assume that on Windows XP that it is already there.
Microsoft's DLL Help Database will tell you for each DLL exactly which versions of which products ship it. You can search it for your specific DLL and see, for example, what is the earliest OS version that ships with it.

I have minimal exposure to RPM, Windows installer mechanics, and WIX. That said, I'm interested in making a cross-platform installer tool (Linux, Windows) that supports upgrading and downgrading (versiona and patches) of my own product. I don't believe this is a topic to be approached lightly; I would like to learn the science of the art (or the art of the science). If I succeed, and build a minimally successful installer tool, it would have these features:
does not depend on a platform-specific tool (such as Windows Installer).
reads XML or a declarative syntax to fulfill installation requirements.
attempts to minimize steps to upgrade or downgrade one of my products (rather than requiring a complete uninstall and re-install).
does not require knowledge of interim product versions, in order to jump versions (i.e. can upgrade one of my products from version 1 to version 3, without passing through version 2).
I'm convinced that "the key" to achieving this goal is by seeing versions as a "point A to point B" problem, which implies that A and B are described by two XML "version" documents that hold info about all the parts and actions (files, or platform specifics such as registry entries). My installer tool would "join" or compare the two documents and determine a minimal set of changes to transform A into B. To some extent, I believe this is precisely what Windows Installer does.
Of course there are further complexities, but that is the point of this post. Where is "the bible" of information on this topic? Remember, I want to make my own installer - not use a platform-specific one. For those who care, my products are usually written in C++ or C#.
Or perhaps I should study something like Steam which is cross-platform and has "automated game updates" as part of its capabilities. In my case, the problem of online deployment is already handled. It is just the final installation step I'm examining. Does Steam use native installers (such as an MSI)? If yes, then that is not what I'm looking for.
In short, what path should I pursue to become somewhat competent on the science of this topic?
I'm not an expert and others can give you better answers but...
Don't declaratively list steps required to install your product - You'll end up making assumptions which will eventually prove wrong. Instead, you should be looking at defining the final state of the installation and let the installer worry about how to make that happen.
Another consideration is that being downgradable may involve huge complications depending on your product - Would it have to down-grade database schemas / file formats / ??? In short, every version of your app will need to be both fully forwards- and backwards-compatible (or at least fail gracefully). Also consider the scenario where V1 of your app stores settings in a file. V2 comes along and adds more settings. You downgrade to V1 - What should it do when changing settings? preserve the V2 settings? dump them? Do some of the V2 settings change the impact/meaning of the V1 settings? Are these decisions to be made by your app or your installer?
Anyway, all that aside, I'd say you need at the least:
A central server/farm with complete files for every version of your App and some API/Web Service which allows the installer to retrieve files/filesets/??? as appropriate (You may be able to tie this into a source control system like svn)
Some way of specifying the desired post-install state of the system in an environment-agnostic way (Think install paths - /usr/??? - should the map to C:\Users\??? or C:\Program Files on windows? Also don't forget it might be a 64-bit machine so it could be C:\Program Files (x86).
A very clever installer written for multiple platforms with as much code re-use as possible (Java, Mono, ???)
The installer should do (simply):
Determine the desired version of the product.
Download/read the appropriate manifest.
Compare the desired situation with the current situation (NB: What is currently on the local system, NOT what should be on the system according to the current version's manifest)
Generate a list of steps to reconcile the two, taking into account any dependencies (can't set file permissions before you copy the file). You can make use of checksums/hashing/similar to compare existing files with desired files - thus only downloading the files actually required.
Possibly take complete backups
Download/unpack required files.
Download/unpack 3rd party dependencies - Later .Net Framework Version/Similar
Perform install steps in atomic a manner as possible (at the very least keeping a record of steps taken so they can be undone)
Potentially apply any version-jump specific changes (up/down-grade db, config files, etc.)
verify installation as much as possible (checksums again)
None of this addresses the question of what to do when the installer itself needs upgrading.
A technique I've used on Windows is that the installer executable itself is little more than a wrapper with some interfaces which loads the actual installer dynamically at runtime - thus I can move files about/unload/reload assemblies, etc... from within a fixed process that almost never changes.
As I said above, I am definitely not an expert, just a novice who's done some of this myself. I sure you can get more complete answers from others but I hope this helped a little
I thought this would be somewhere on the Web, but I couldn't Google it:
Given the complexity involved in creating an MSI package (compared to NSIS, InnoSetup, etc.), what would be a compelling reason to go through all the mess (using MSVS's crappy setup project wizard, learn a whole new langauge/ecosystem just to make the installer (WiX), or pay heavy license fees (InstallShield)) for the sake of making an MSI installer?
Would be nice to have real world opinions or experience (even to prove that MSI is really worthless) other than the obvious MSDN page, for instance :)
I don't think there is one prime advantage for all situations. Here are some things I like about it, vs other kinds of installers:
Install logic and code is contained in a database, which is in an accessible format.
I like this a lot when I'm debugging. Rather than rebuilding your installer, you can directly edit the database with a tool like Orca (free database editing download from MS), then run the install again to test your changes. Update your custom code, temporarily condition something out, change the order of operations, whatever you need to do.
Patching. The Installer service and its corresponding tools know how to create patches containing deltas of updated files, rather than complete files. It allows maintenance sizes to remain reasonable.
Administrative Images. The installer can create an administrative image. If you've generated patches, you can apply the patches to the administrative image, and new installations can then be run from the administrative image rather than the original installer. Like slipstreaming patches in OS images. If you're pushing your app out to a large number of machines, it's pretty cool to not need to push a bunch of patches out post-install.
Other interesting features include transforms, run from source, detect and repair, component sharing, and so on.
Take a look at this:
https://serverfault.com/questions/11670/advantages-of-using-msi-files
MSI (or ClickOnce) was required to obtain the Windows Vista Logo Program (Microsoft official certification). I believe this requirement was removed with Windows 7, but it's still easier to get certification with MSI (see here).
You don't need to buy any expensive 3rd party installer package though. If you're going for MSI, I suggest you use WIX and learn it. Once you're familiar with it, it works pretty well.
Another good read is:
Windows Installer: Benefits and Implementation for System Administrators
I've been a full time setup developer for 14 years. My first 7 years were InstallScript Setup.exe style projects and my last 7 years have been MSI based. At first I resisted MSI and then after 6 months of using it I became a true believer in how much better it is.
I'm pretty certain that there are enterprises that require MSI formats to remote bulk install an application on thousands of machines. However I don't deal with such organizations so don't know for certain.
At the moment I have no images being picked up at the moment, and this is off a completely default Sitecore Xpress install.
I think this version is based on a 6.0 release
I have installed it on a XP machine (no images) and then tried running it through WebMatrix, still with no images.
I am at a loss really, and I have been grasping at straws a little.
Unfortunately I don't have much expirience with the Xpress edition.
But one thing is that you need to have the mime-types setup on the webserver for the .ashx's to work properly.
Though this should be done for the most common kinds, it's usually not done for .flv files, so they wouldn't work.
There will be some stuff registered in the web.config file about files types (at least in non Xpress editions) and also in App_Config/Filetypes.config (though the ones in the web.config will be commented out in the Filetypes.config and should stay that way).
I hope this can help somewhat.
I've been given the task of re-engineering a really old VB3 application. As part of this I have an XP virtual workstation upon which I've installed VB3 Pro, so I can create a running verison of it to help me emulate it, but the VB3 app uses a control called VBSQL.VBX, which didn't come with VB3 Pro, apparently. I've checked Microsoft's site, but there are only seven pages in the search result for VBSQL.VBX, and none of them offers an install.
Does anyone here have any idea where on earth I can obtain VBSQL.VBX?
Via http://support.microsoft.com/kb/111490, "Microsoft SQL Server Programmer's Toolkit for Visual Basic".
It looks like they offer the .ocx here: http://support.microsoft.com/kb/186893, possibly there is a VBX as well?
Whenever I run into an issue like this I usually end up creating a mock object with the same public members as the class in question. Sometimes it works out better as I can fake the data I want to pass around so I can run tests that would otherwise prove difficult.
If you can't find this file this is the approach I would recommend.
I'm trying to implement a version control system, but as most of us know designers don't feel comfortable with version control systems. I'm looking for a solution mostly for our designers using Photoshop, Flash and other design tools.
It's not a big deal to use a version control system, like VSS 2005, with our frontend and backend coders, but we have some serious problems with our designers. They mostly refuse to use version control systems, and they are right at some points, mostly on productivity level. They mostly work on more than one file, and on more than one application like Photoshop and Flash.
I don't know if version controlling is the right answer or not. Maybe we have to implement a backup system, but there has to be a versioning system, I think. I and our designers are very tired of doing the same thing or going back to the previous designs over and over again.
It would be wonderful to know how digital agencies overcome this problem. If version controlling is the answer, please share your tips on how to make designers comfortable with version controlling.
EDIT 1: Maybe it would be great to have a solution like Dropbox, as it doesn't disturb you with check-ins/check-outs. All you have to do is to open up a file, work on it and save it, the rest is handled by Dropbox.
EDIT 2: We are on Windows, so no chance to implement anything other than Windows support :(
Thanks...
I haven't actually ever done this with graphic designers, but is it possible that Subversion's WebDAV support might work for them? You can mount a WebDAV share as a drive under Mac OS X and Windows XP & Vista, I believe. Each save becomes a new revision in the repository.
And as for your second, hidden question: Yes, you do need to implement a backup system. At least if you value your data.
Adobe has it's own version control, Version Cue, which is bundled with the Creative Suite package. http://www.adobe.com/products/creativesuite/versioncue/sdk_overview/ Apparently, Eclipse can plug into this. I haven't tried it extensively, but I know it integrates nicely into the file dialog in Creative Suite.
NOTE: Version Cue has been discontinued by adobe after the release of CS5:

Adobe Version Cue maybe?
You might want to try subversion because there are plugins for windows explorer and max OS X finder. integration with the filesystem has been a big help for me on projects where non-developers had to work with source control. This includes projects that have had designers.
Another key thing that helped was having a good directory structure for the files the designers and other non-developers worked with.
I just came accross ConceptShare and it's pretty great...it's not automated version control but you could use it for that and it's a great way to collect and document feedback.
You can try Subversion (installed on a local or remote server) plus Adobe Creative Suite plug-in that would face the designers - Pixelnovel Timeline
It's compact, has previews of all versions (submitted via the plug-in), works for Photoshop, Illustrator & InDesign.
If developers also use Subversion, everything (code & design) can be kept in one place.
Instead of trying to integrate a version control system with lots of applications on different operating systems, you might want to have a look at copy-on-write file systems such as http://en.wikipedia.org/wiki/Ext3cow. That way your designers won't even notice a difference; all they will have to do is save their work to a network share on a linux/samba server using ext3cow.
I'm both a designer and coder. I usually version control code (text data) with git, and simply use "save as" with a version name for graphics (binary data). And I run Apple's Time Machine on top of all that, for safety.
To me, version control on graphic files would just be a burden. I'd have to roll back to see changes, and you wouldn't even get one of the great features of version control: see the changes you did in a specific commit just by looking at diffs. The log feature is nice though, to see how you progressed in time, and notes, but to me personally it's not worth it.
Take a look at Perforce - it has a plugin and tools that allow you to use it from within designer tools such as Photoshop, its also super fast and integrates well with Visual Studio - runs on Windows as well as Linux
What I did once was create a "Snapshot" shortcut on the desktop that added and committed everything from a specific directory.
If every designer commits to their own branch (trivial with a DVCS but easy with SVN too) there will be no conflicts, and the cross-branch merging can be done at intervals by someone who isn't afraid of it.
I've been having my eyes on GridIron's Flow for a while now. It looks like a competent version control suite that has some neat asset management features such as visualization on graphics between versions and relationships between different assets. Flow has support for handling files for adobe photoshop, illustrator, flash etc. However as of now (early january) GridIron hasn't released Flow yet other than having to announce the beta program.
Most digital agencies that I know of that mainly do web development use Subversion for version control. To avoid conflicts on image files an artist will lock the files he or she will work on. That way, another artist won't do the mistake of overwriting changes. This requires some coordination among artists and devs so that noone steps on anyone shoes. Also, if someone forgets to unlock, there is the possibility to break locks.
If you're into distributed version control you might want to take a look at Mercurial as it has good support for Windows and has some neat cheat sheets. The Ruby kids are using git but is rather lacking in Windows.
Before using version control with artists, at least make sure they know the basics of version control and let them fool around with it in a sandbox. Also make sure they've set up some basic rules of conduct when collaborating with each other and interacting through version control (i.e. ways to make sure they don't destroy each others works or step on each others toes).
